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.

graph.
VS. time
Answer herede
SUBMIT
Answer:
The correct answer is - velocity (velocity VS. time).
Explanation:
Acceleration is a vector quantity that is the rate of change in the velocity at a change in time. The formula for the acceleration is a = Δv/Δt., where a is acceleration and Δv is the change in velocity and Δt is the change in time.
In a velocity-time graph, velocity is denoted on the Y-axis whereas time is denoted on the X-axis. The Slope of a graph found is the ratio of the velocity over or VS. time.

Some orchids produce two types of flowers, one with only anthers and the other with only carpels. And on some orchids like this, the flowers look very different from on another. An explanation for this difference is
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.

The number of possible genetically different gametes for an organism equals
2N, where Nis the number of pairs of chromosomes. If an organism has four
pairs of chromosomes, how many different gametes can it produce?
O A. 16
O B. 4
O C. 8
O D. 32
Answer: it’s 16
Explanation: i took the quiz
If an organism has four pairs of chromosomes, 16 gametes can it produce. So, the correct option is A.
What are Gametes?A gamete is defined as the reproductive cell of an animal or plant while the female gamete is called the ova or egg cell, and the male gamete is called the sperm in the animal cells. Ova and sperm are haploid cells with each cell containing only one copy of each chromosome. During fertilization a sperm unite with the ovum to form a new diploid organism.
When the organism has four pairs of chromosomes, 16 gametes can it produce. In seed plants, the pollen is called the male sperm that produces the gametophyte while the female gametes are contained within the ovary of the plant.
So, the correct option is A.

n a simple food chain, wolves eat deer and deer eat shrubs. A pack of wolves has a total biomass of 1,000 kilograms. Approximately what biomass of shrubs must have been eaten by deer to support that wolf pack, assuming that only shrubs, deer, and wolves exist in the food chain
Answer: 100000 kg of biomass of shrubs must be eaten by deer.
Explanation:
According to the Lindeman 10% law :
When energy is transferred from one tropic level to another successive tropic level, only 10% of the energy gets transferred while the remaining is lost in the environment.
We are given:
Biomass of the pack of wolves = 1000 kg
This means that 10% of the biomass of deer is 1000 kg
Biomass of deer will be:
[tex]10=\frac{1000}{x}\times 100\\\\x=\frac{1000\times 100}{10}=10000kg[/tex]
Now, this biomass of deer is 10% of shrubs' biomass.
This means that 10% of the biomass of shrubs is 10000 kg
Biomass of shrubs will be:
[tex]10=\frac{10000}{y}\times 100\\\\y=\frac{10000\times 100}{10}=100000kg[/tex]
Hence, 100000 kg of biomass of shrubs must be eaten by deer.

SUBMIT
Answer:
A
Explanation:
Conduction is the exchange of energy as warmth or power starting with one iota then onto the next inside an article by direct contact. Conduction happens in solids, fluids, and gases. Nonetheless, solids move energy most proficiently since the atoms in solids are most firmly stuffed, and the particles are nearer together, as displayed in this figure. For fluids and gases, the thickness of the particles are by and large lower than those of solids and the particles are farther separated, so the energy move is less productive.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.
