Recall the chemical reaction of photosynthesis: 6CO2 + 6H20 - C6H12O6 + 602. Why are forests
referred to as "carbon sinks"?

Answers

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?

Answers

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.

Answers

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.

Answers

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.

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.

pairs of chromosomes, how many different gametes can it produce?
O A. 16
O B. 4
O C. 8
O D. 32

Answers

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

Answers

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.

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.
