Albinism, caused by the non-production of tyrosinase, is an autosomal recessive condition, a woman of normal pigmentation, whose father was albino, marries an albino man. What is the probability that of 6 children procreated, the first is albino, the second is of normal pigmentation, and of the next 4, 2 are of normal pigmentation and 2 is albino?
Select one:
a. 37.5%
b. 25%
c. 50%
d. 9.5%

Answers

Answer 1

The probability that of 6 children procreated, the first is albino, the second is of normal pigmentation, and of the next 4, 2 are of normal pigmentation and 2 is albino is C. 50%.

How to calculate the probability?

Probability simply means the likelihood that something will occur.

In this case, albinism, caused by the non-production of tyrosinase, is an autosomal recessive condition whereby a woman of normal pigment marries an albino man.

In this case, there are 3 albino and 3 normal pigmentation based on the information.

This will be:

= 3/6 × 100

= 50%

The probability is 50%.

Some plant tissue is exposed to a concentrated solution, which causes the plant cells to lose water. As a result, the plant wilted.

State the scientific term used to describe the appearance of cells within the wilted plant tissue.

Your answer

Answers

Plasmolysis is the loss of water by plant cells after being placed in a solution with a higher concentration of solute than the cells. This is called a hypertonic solution. Osmosis causes water to flow from the cell into the surrounding liquid.

Plasmolysis is the process by which cells lose water in hypertonic solutions. When cells are in a hypotonic solution the reverse process cytolysis or cell lysis occurs resulting in a decrease in external osmotic pressure and a net flow of water into the cell. When plants are not watered the extracellular fluid becomes isotonic or hypertonic causing water to leave the plant cells.

This causes a loss of turgor pressure. You will probably notice it as a wilt. In more concentrated solutions cell contents lose water by osmosis. They contract and move away from the cell wall. Cells are limp It is cytolyzed. When a high concentration of salt is placed on the outside of the cell membrane water leaves and binds with the cell. As water is lost by this movement, the plant cells shrink and die. Because of this, salt can kill plants. It leaches water out of the cells.

the half life of plutonium-239 is 24,300 years. If a nuclear bomb released 8 kg of this isotope, how many years would pass before the amount is reduced to 1 kg?

Answers

The number of years passes before the amount of 8 kg of plutonium-239 will reduce to 1 kg is equal to 72900 years.

What is the half-life of a radioactive element?

The half-life period of the radioactive element can be described as the time required to reduce its original amount to half after disintegration.

Given, the original amount of plutonium-239 (N₀) = 8 kg

The amount remaining after disintegration (N) = 1 kg

Consider that 'n' is the number of half-lives.

N ×2ⁿ = N₀

1 ×2ⁿ = 8

2ⁿ =8

2ⁿ = 2³

n = 3

Now, the number of half-lives (n) of plutonium-239 = 3

Half-life of plutonium-239 (t½) = 24300 years

t = n ×t½

t = 3 ×24300

t = 72900 years

Therefore, 8Kg of plutonium-239 will take 72900 years to reduce to 1 kg.

Those messages are sent to the hand using sensory neurons.

Axons are long single fibers that carry messages from the cell body to the dendrites of other neurons or other body tissues such as muscle. In muscles, this electrical message causes them to contract or shorten. Think of catching a ball. The brain tells neurons to send electrical signals to the neuromuscular junction. This releases neurotransmitters into your finger muscles, which contract to catch the ball.

Motor neurons release chemicals that are taken up by muscle fibers. This causes the muscle fibers to contract and the muscle to move. Neurons carry messages from the brain through the spinal cord. These messages are sent to the muscles, directing muscle fibers to contract and causing the muscles to move. Neurons that are sending signals release chemicals called neurotransmitters. This chemical binds to receptors on the surface of receiving neurons.

A group of ranchers was very concerned about a local wolf population that they thought was preying on their livestock. After several attempts, they persuaded a court to authorize a hunt in order to eliminate the wolf population in their area. The court set a quota of 200 wolves, to be eliminated over the course of six months. 15. State a negative effect that the removal of these wolves might have on the habitat. 16. How would this hunt affect the biodiversity of the area's natural ecosystem? 17. Suppose that you are a local environmental offi- cial in the area. Propose a plan that would pre- serve the wolves yet keep them away from the ranchers' livestock.

Answers

Explanation:

The wolf, like other large predators, is a key species in the functioning of ecosystems, since they regulate food chains from the top link. Now, with the excessive hunting of this great predator, there is an ecosystem imbalance because the food web where the wolf is involved would be destabilized. The absence of these carnivores can cause populations of their prey such as herbivores (moose) to increase dramatically and the vegetation of the natural area to be affected due to excessive herbivorous activity. This can cause biodiversity to be affected because the riparian forests (willows, poplars, alders) can be destabilized and therefore also the banks of the rivers. Therefore, the loss and deterioration of habitats is the main cause of biodiversity loss.

We can conclude that the correct answer is:

Answer:

15. Ecosystem imbalance due to the destabilization of the food web where the wolf is involved.

16. The absence of these carnivores can cause populations of their prey such as herbivores (moose) to increase dramatically and the vegetation of the natural area to be affected due to excessive herbivorous activity. This can cause biodiversity to be affected because the riparian forests (willows, poplars, alders) can be destabilized and therefore also the banks of the rivers. Therefore, the loss and deterioration of habitats is the main cause of biodiversity loss. In fact, many scavenger species (magpies, eagles, ravens, bears) depend on wolves because they can prey on the remains of wolf prey. If there is damage to the vegetation of the natural area due to the excessive hunting of wolves, many birds would be affected, as well as beavers, amphibians, reptiles, and fish.

17. First of all, new or novel herding devices and herding methods must exist so that wolves do not get used to them and lose their natural wariness and caution. Increasing risk perception in wolves can help reduce livestock deaths caused by wolves. On the other hand, it is also possible to build pens to keep the cattle overnight in a small paddock, instead of fencing off large paddocks of many hectares. Finally, sheep and goat farmers around the world have been seen to use guard dogs to guard their livestock against carnivores and in most cases, the mere presence of the dogs seems to help keep wolves away from livestock.

Keeping a good record of the number of wolves in a natural area can be a valuable tool in resolving cattle-wolf problems. Observation records can help identify trends, problem areas, and vulnerable times of the year, helping to increase the effectiveness of preventative measures. For example, keeping good records helps identify grazing areas where predator problems repeatedly occur.

Meiosis is a cell division process that produces four haploid cells (gametes) form one diploid cell (sex cells). It is divided into two stages (meiosis 1 and 2) with four phases each. Story in the explanation.

What is meiosis?

Meiosis is the cell division process through which a diploid cell (2n) produces four haploid daughter cells (n).

After DNA replication there are two meiotic phases.

The first one is a reductive phase, in which homologous chromosomes separate. In the second phase, the cell suffers a new, not reductive division.

Story

I am a chromosome from a sex cell. I suffer a few modifications when the cell enters the cell division process.

There is a reductive first stage called meiosis I. During this phase, I go through 4 steps,

In the prophase, I condensate and become visible. My homologous chromosome gets near me, and we interchange fragments of our bodies. This event is the crossing-over.

During the metaphase, my homologous and I align in the equatorial plane, where all chromosomes arrange before being separated.

Once the anaphase begins, my homologous and I separate. Each of us migrates to opposite poles.

When I reach my pole, I get together with other chromosomes, and a nuclear membrane surrounds us. This phase is the telophase.

The cell suffers cytokinesis, and two haploid cells are formed. I am in one of them.

The second phase is called Meiosis II. Before this phase, we duplicate.

In the prophase, my duplicated chromosome and I stick together. Now I am a chromatid, and my duplicated form is my sister chromatid. We are visible, and we are together.

In the metaphase, my sister and I migrate to the equatorial plane of this new haploid cell.

In the anaphase, some enzymes break the bonds that keep my sister and me together, and we migrate to different poles again.

In the telophase, I reach a new pole where I join other chromosomes. And again, a new nuclear membrane surrounds us.

Cytokinesis occurs again. I am now part of one of the four haploid cells (gametes).
