Answer: The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. This is the process called Photosynthesis, by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.

Explanation:

During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food). The photosynthesis process occurs in all plants and algae, as well as in some bacteria species.

One of the largests causes of deforestation and forest degradation is the agricultural expansion. Agricultural expansion is used to make large-sacale livestock ranching and plantation overtacking small-scale farming, the expansion of the plantation needs wide and flat areas to be able to be used for crop purposes, being the direct driver of almost 80% of tropical deforestation (Brasil is one of the countries that is going through this kind of deforestation in Amazon region). The acceleration and intensification of the agricultural expasion has resulted negative impact to rainforests, loss of biodiversity, and general changes to climate in the locals affected by the agriculture advance.

Explanation:

This question is a dihybrid cross involving two genes, one coding for feather color and the other for beak length. The alleles for green feathers (G) and long beak (L) are dominant over the alleles for yellow feathers (g) and short beak (l).

According to this question, a male with genotype GGLl was crossed with a female with genotype Ggll. The following combination of gametes is produced by each parent:

GGLl - GL, Gl, GL, and Gl

Ggll - Gl, Gl, gl and gl

Using these gametes in a punnet square (see attached image), the following offsprings in the following proportions will be produced.

Green feathers, long beak (GGLl, GgLl) = 8/16 or 1/2

Green feathers, short beak (GGll, Ggll) = 8/16 or 1/2

Hence, the probability of short beaks (ll) in the offspring of the cross is 1/2.

Answer:

The correct answer is: C.

Muscle cells require more energy for contraction than any other cell. Hence, option C is correct.

The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).

It generates ATP through the process of oxidative phosphorylation. Small chromosomes found in mitochondria are found there. In most cases, mitochondria and consequently mitochondrial DNA are exclusively passed down from the mother.

Muscle cells contain a large number of mitochondria because they require more amount of energy for contraction. Hence, option C is correct.

The electric potential at a point on the axis of the annulus a distance z from its center is given by:  \(V = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

To exploit the angular symmetry of the problem, we can consider a circular ring of radius r and thickness dr, with charge density λ. The potential dV at a point P on the axis of the ring, at a distance z from the center of the ring, due to a small element of charge dq on the ring is given by:

\(dV = kdq / sqrt(r^2 + z^2)\)

where k is the Coulomb constant.

We can express the charge density λ in terms of the total charge Q on the ring and the circumference C of the ring as:

λ = Q / C = Q / (2πr)

Substituting this expression into the equation for dV and integrating over the entire ring, we get:

\(V = ∫dV = kQ / (2π) ∫dr / sqrt(r^2 + z^2)\)

To evaluate the integral, we can make the substitution \(u = r^2 + z^2, du = 2rdr,\)  to obtain:

\(V = kQ / (4πz) ∫du / sqrt(u) = kQ / (4πz) * 2sqrt(u) = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

Therefore, the electric potential at a point on the axis of the annulus a distance z from its center is given by:

\(V = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

Answer:

Berries. High in fiber, berries are naturally sweet, and their rich colors mean they are high in antioxidants and disease-fighting nutrients.

How to include them: When berries are not in season, it is just as healthy to buy them frozen. Add to yogurt, cereals, and smoothies, or eat plain for a snack.

Fish. Fish can be a good source of protein and omega-3 fatty acids, which help prevent heart disease.

How to include it: Buy fresh, frozen, or canned fish. Fish with the highest omega-3 content are salmon, tuna steaks, mackerel, herring, trout, anchovies, and sardines.

Leafy greens. Dark, leafy greens are a good source of vitamin A, vitamin C, and calcium, as well as several phytochemicals (chemicals made by plants that have a positive effect on your health). They also add fiber into the diet.

How to include them: Try varieties such as spinach, swiss chard, kale, collard greens, or mustard greens. Throw them into salads or sauté them in a little olive oil. You can also add greens to soups and stews.

Nuts. Hazelnuts, walnuts, almonds, pecans — nuts are a good source of plant protein. They also contain monounsaturated fats, which may be a factor in reducing the risk of heart disease.

How to include them: Add a handful to oatmeal or yogurt or have as a snack. But remember they are calorically dense, so limit to a small handful. Try the various types of nut butters such as peanut (technically a legume), almond, or cashew. Nuts are also a great accompaniment to cooked veggies or salads.

Olive oil. Olive oil is a good source of vitamin E, polyphenols, and monounsaturated fatty acids, all which help reduce the risk of heart disease.

How to include it: Use in place of butter or margarine in pasta or rice dishes. Drizzle over vegetables, use as a dressing, or when sautéing.

Whole grains. A good source of both soluble and insoluble fiber, whole grains also contain several B vitamins, minerals, and phytonutrients. They have been shown to lower cholesterol and protect against heart disease and diabetes.

How to include them: Try having a bowl of oatmeal for breakfast. Substitute bulgur, quinoa, wheat berries, or brown rice for your usual baked potato. When buying breads at the supermarket, look to see that the first ingredient is “100% whole wheat flour.”

Yogurt. A good source of calcium and protein, yogurt also contains live cultures called probiotics. These “good bacteria” can protect the body from other, more harmful bacteria.

How to include it: Try eating more yogurt, but watch out for fruited or flavored yogurts, which contain a lot of added sugar. Buy plain yogurt and add your own fruit. Look for yogurts that have “live active cultures” such as Lactobacillus, L. acidophilus, L. bulgaricus, and S. thermophilus. You can use yogurt in place of mayonnaise or sour cream in dips or sauces.

Cruciferous vegetables. These include broccoli, Brussels sprouts, cabbage, cauliflower, collard greens, kale, kohlrabi, mustard greens, radishes, and turnips. They are an excellent source of fiber, vitamins, and phytochemicals including indoles, thiocyanates, and nitriles, which may prevent against some types of cancer.

Answer:

Melanin absorbs dangerous UV rays that can do severe skin damage. But melanin can't absorb all the UV rays, and some people don't have much melanin in their skin.

Explanation:

The sun is by far the strongest source of ultraviolet radiation in our environment. Solar emissions include visible light, heat and ultraviolet (UV) radiation. Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide. UVA is not filtered as significantly by the atmosphere.Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced. Consequently, the people and the environment are exposed to higher levels of UV radiation, especially UVB.

Ozone depletion is caused by human-made chemicals released into the atmosphere and will continue until the use of chlorine and bromine compounds is drastically reduced. International agreements, in particular the Montreal Protocol, are gradually succeeding in phasing out the production of ozone-depleting substances. However, the long life span of the chemicals already released will cause ozone depletion problems to persist for many years to come. A full recovery of the ozone level is not expected until 2050.Most UV-A does reach the surface, but UV-A does little genetic damage to tissues. UV-B is largely responsible for sunburn and skin cancer, though it is mostly absorbed by ozone before reaching the surface. Levels of UV-B radiation at the surface are especially sensitive to the amount of ozone in the stratosphere.

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.

The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.

Assuming a diallelic gene,

Allelic frequencies

Genotypic frequencies

The addition of the allelic frequencies equals 1

p + q = 1.

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example,

Alleles          Frequencies

Genotypes

We need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate  genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).

Genotypic and Phenotypic frequencies

F(S^AS^A) = p² = 0.6² = 0.36

F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48

F(S^BS^B) = q² = 0.4² = 0.16
