Beans may be tall or short depending on one locus, and they may have long or stubby pods, depending on another locus. A tall, stubby plant was crossed with a short, long plant. The F1 plants were all tall and stubby. Which of the following PHENOTYPES do you expect to occur least often in the F2?"
a. "tall, stubby"
b. "short, stubby"
c. "short, long"
d. "tall, long"
Answer:
c. "short, long"
Explanation:
The question being described involves two different genes; one coding for beans length and the other for pod length. According to the question, beans may be tall (T) or short (t) while they can also have have long (L) or stubby pods (l).
From the phenotypic ratio result of the F1 generation, which were all tall and stubby, it is clear that tall bean (T) and stubby pods (d) are highest balloon. According to Gregor Mendel's ratio of dihybrid cross; 9.3.3:1, the least occuring phenotype, which is 1 of 16, can be "short, long".

non of these
cold water
warm water
Answer:
warm water
Explanation:
Kinetic energy refers to the energy that possesses an object due to the motion of its molecules. Kinetic energy is positively associated with temperature. When heating water, water molecules gain kinetic energy and move faster than the molecules of cold water. In consequence, the temperature of an object can be considered as the average amount of kinetic energy that its molecules carry.

What usually happens as more farmland is converted to urban land?
A. People grow more crops
B. The amount of cropland increases
C. People eat more fresh foods
D. Food prices increase
Food prices increase when more farmland is converted to urban land. The correct option is D.
What are farmlands?Farmland is land that is temporarily covered in agricultural crops (areas with numerous crops are only included once), temporary grazing or mowing meadows, market and kitchen gardens, and land that is temporarily fallow.
Urban development entails transforming a region into an urban state in a variety of ways, including physically, geographically, economically, and societally, through changes in population and land use.
Food security decreased agricultural output, and agricultural labor is only a few of the repercussions of turning farmland into urban expansion. Because there is less land available for crop cultivation as a result of urban growth, local food prices may rise.
Therefore, the correct option is D. Food prices increase.

D.life processes of animals
Helppppp I will make brainliest
The process of photosynthesis adds oxygen to the atmosphere. Option C is correct for the given statement. In the atmosphere, nearly 21% oxygen is present.
What is the gas constituent of the atmosphere?In the atmosphere, different gases such as oxygen, nitrogen, carbon dioxide, and water vapour are present. These differ in composition, with oxygen accounting for 21%, nitrogen accounting for nearly 78%, and carbon dioxide accounting for less than 1%.
The oxygen is produced by the process of photosynthesis that is undertaken by green plants. The phytoplankton, algae in aquatic habitats, and plants of the terrestrial ecosystem do photosynthesis because of the presence of chloroplasts.
This oxygen is used by animals and plants for cellular respiration. Others are incorrect options because forest fires increase carbon dioxide in the atmosphere, animals take oxygen from the atmosphere, and rock weathering does not add oxygen.
As a result, option C is the correct answer because photosynthesis produces oxygen for the atmosphere.

In addition, biomes encompass a set of ecosystems such as tundra, rainforest, savannas, wetlands, among others. On the other hand, an ecosystem is a community of organisms that interact with other organisms and abiotic factors. According to the above, the correct answer is D. Ecosystems are always smaller than a biome becaause biomes includes ecosystems with similar features.
A protein has a molecular mass of 400 kDa when measured by gel filtration. When subjected to gel electrophoresis in the presence of sodium dodecyl sulfate (SDS), the protein gives three bands with molecular masses of 180, 160, and 60 kDa. When electrophoresis is carried out in the presence of SDS and b-mercaptoethanol, three bands are again formed, this time with molecular masses of 160, 90, and 60 kDa. Determine the subunit composition of the protein (how many and what sizes) and why you observe the different banding pattern under the two conditions.
Answer:
subunit composition
how many: 4 subunitswhat sizes: 160 kDa, 60 kDa, 90 kDa, and 90 kDa.Explanation:
SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. However, the detergent can not disrupt disulfide bridges, so these bonds remain together. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be. The speed of displacement in the electromagnetic field is inversely proportional to the protein size.
On the other hand, b-mercaptoethanol acts as a reductive agent, breaking disulfide bonds. This chemical produces a complete denaturalization resulting in the unfolded protein. If disulfide bridges kept two protein subunits together, the b-mercaptoethanol separates them.
So, the most important data we need to consider here is that SDS can not disrupt disulfide bridges, while b-mercaptoethanol can.
Available data:
A protein has a molecular mass of 400 kDaSDS → three bands with molecular masses of 180, 160, and 60 kDaSDS + b-mercaptoethanol → three bands with molecular masses of 160, 90, and 60 kDaSDS
180 + 160 + 60 = 400 kDa
SDS + b-mercaptoethanol
160 + 90 + 60 = 310 kDa
The difference between them is 400 - 310 = 90 kDa, meaning that there is a subunit of 90 kDa that is not being detected by SDS alone.
From both measures ( SDS and SDS/b-mercaptoethanol) we can assume that subunits 160 kDa and 90kDa are the same. So the difference is in the left subunit ⇒ 180 and 90, respectively.
180 - 90 = 90 kDa
We can assume that the 180 kDa subunit is composed of two 90 kDa subunits joined by a disulfide bridge. SDS alone could not disrupt this bond, so it detected a unit of 180kDa. b-mercaptoethanol detected this bond and broke it, generating two 90 kDa units, which migrated together in the gel, so they were expressed as the same band.
This difference suggests that the protein is formed of 4 subunits. One of them is 160 kDa, another one is 90 kDa, and the last two subunits are 90 kDa each.

Pancreatic cells that are responsible for creating several digestive enzymes (proteins) [Ribosomes]
Explanation:
Mitochondria are cell organelles whose main function is energy generation during respiration. They generate energy in the form of ATP which is then used by the cells and tissues for various metabolic function. Mitochondria are abundant in cells whose energy requirements are high such as muscle cells. Therefore, insects flight muscles will have an abundance of mitochondria.
Cilia are finger-like projections on respiratory surfaces whose sweep-like movements help to move particles and fluids out of the airways. In the trachea, the cilia trap particles like bacteria and viruses and then move these trapped particles along with mucus up to the pharynx where it is either coughed out or swallowed into gastrointestinal tract. Therefore, respiratory surfaces like the trachea will have an abundance of cilia.
Lysosome are cell organelles which function to destroy and digest foreign and cellular proteins in the cell. They have an abundance of proteolytic enzymes which degrade proteins at acidic pH. Therefore, white blood cells that engulf and destroy invading bacteria will have an abundance of ysosomes.
Chloroplasts are plant cells organelles which are the sites for photosynthesis. It is abundant in the leaves of plants where photosynthesis mainly take place. Therefore, leaf cells of cacti will have an abundance of chloroplasts.
Golgi apparatus is a cell organelle that helps process and package proteins and lipid molecules, especially those that are to be secreted outside the cell, packaging them into vessicles. They also make and secrete mucus. Therefore, goblet cells lining the intestinal tract that secrete mucus will have an abundance of Golgi apparatus.
Ribosomes are cell organelles whose main function is to synthesize proteins, both for intracellular and extracellular purposes. Proteins such as hormones, enzymes etc, are synthesized by the ribosomes. Therefore, pancreatic cells that are responsible for creating several digestive enzymes (proteins) will have an abundance of ribosomes.

Recall the chemical reaction of photosynthesis: 6CO2 + 6H20 - C6H12O6 + 602. Why are forests
referred to as "carbon sinks"?
Answer:
Because they absorb and store more carbon in form of CO2 during photosynthesis than they release
Explanation:
A "sink" as opposed to source is a site where something is deposited or stored rather than produced. Plants in the forest vegetation are capable of a unique process called photosynthesis, in which they manufacture their food using inorganic carbon as powered by light energy. The photosynthetic equation is given below;
6CO2 + 6H20 → C6H12O6 + 602
Based on the equation above, carbon dioxide is required for photosynthesis and is obtained from the atmosphere via the stomata on the leaves. This means that carbon in form of CO2 must be stored in the plant prior to photosynthesis, hence, FOREST is referred to as CARBON SINKS because it absorbs and stores more carbon (CO2) during photosynthesis than it gives out.
Why are forests important for helping to control the rate of climate change?
Answer: Forests are a stabilizing force for the climate. They regulate ecosystems, protect biodiversity, play an integral part in the carbon cycle, support livelihoods, and supply goods and services that can drive sustainable growth.
Explanation:
The forest helps to maintain ecological balance, carbon cycle and rainfall.
How forest maintains ecological balance?"Ecological balance is a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession."The forest prevent soil erosion and maintain soil fertility. It establish oxygen and carbon balance in nature.It absorbs harmful gases like carbon from environment. What is carbon cycle?"The carbon cycle is biogeochemical cycle by which carbon is exchanged among the biosphere, hydrosphere and atmosphere of the earth."Forests takes up carbon from atmosphere and gives out oxygen.Forest helps in decay, disturbance and renewal of carbon.Hence, the forest regulate rainfall, ecological balance and carbon cycle.

Suppose that you compare the amount of food needed by four groups of lizards, each of which has a metabolic rate that is expected for its body size. There are 10 lizards weighing 10 g each, 5 lizards weighing 20 g each, 2 lizards weighing 50 g each, and a single 100-g lizard. Assuming equal digestibility, similar food, and so on, the _______ lizards need the most food.
A. 10-g
B. 20-g
C. 50-g
D. 100-g
E. All of the above need the same amount of food.
Answer:
The _10 gr__ lizards need the most food.
Explanation:
Metabolic rate: Refers to the energy used by the organism during a period of time. Small animals have higher metabolic rates than big animals to maintain energy levels. In general, small animals are more active than big animals. The amount of food needed by the animal to keep energy and body mass depends on the individual´s metabolic rate.
If small animals have a higher metabolic rate than big animals, then they need more food to maintain their energy levels. The relationship size-metabolic rate can be applied to different species -such a mouse and an elephant-or to the same species -like the one of the exposed example-.
So, in comparison, and considering their body sizes, 10 g lizards have the highest metabolic rate, meaning that they need the most food -again, considering their sizes- to keep energy and body mass constant.

6. Discuss how polymorphism in the cnidarians might have influenced adaptive radiation of the group.
Answer:
Explanation:
The class Anthozoa of the phylum Cnidaria includes a wide range of corals and marine animals. Cnidarian polymorphism: Medusa and Polyp are two phases wherein cnidarians vary their morphology for adaption, resulting in them mostly existing as dimorphic zooids. Finally, as the medusa stage develops, these colonial polyps might differentiate into specialized forms.
Medusa forms possess velum, manubrium, defined radial canals, and accompanying ring canal, as well as other components like ocelli and statocysts, demonstrating their adaptability to their survival. Polyp stages have adaptive radiation, including such stolon and structures like hydranth and planula, to help them escape predators. Other structures commonly found include gonangia and gonopore.
Hydra is a kind of freshwater animal belonging to the class Cnidaria. Hydra is diploblastic, which implies it has two tissues: nerve and muscular tissue. Mesoglea is a gel-like material that separates the epidermis and the gastrodermis. Charles Darwin used these finches in his experiments to illustrate how changes in the environment, allelic alterations, and mutation effect affected the species' adaptive radiation.

Answer:
The Orchids is the diversified structures of flowers, in fact, they have unique feature. Even with the pollination, they have several mechanisms of pollination. Few of them include:
1. Few orchids have self-fertilization where the anther converts from solid-state to a liquid state without any aid of an external pollinating agent.
2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.
3. This happens through an external pollinator resulting in a diversity of species.
4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.
5. These types depend on ants and other insects to get pollinated.
6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
