What can fatty acids do to help with PDCD

Answer:

In genetics, a trait is considered dominant when it is expressed in the phenotype of a heterozygous individual, meaning that it only requires one copy of the dominant allele to be expressed. On the other hand, a recessive trait is only expressed when both copies of the allele are present in the individual's genotype.

To provide the best evidence that a trait is dominant, we would need to observe the trait in the phenotype of all individuals who carry at least one copy of the dominant allele. This means that if an individual has one dominant allele and one recessive allele, they should still show the dominant trait in their phenotype.

In practice, this could be demonstrated through a series of crosses between individuals with known genotypes. If the offspring of a cross between a homozygous dominant individual and a heterozygous individual all show the dominant trait, this would be strong evidence that the trait is dominant. Similarly, if the offspring of a cross between two heterozygous individuals show the dominant trait in a 3:1 ratio, this would also support the idea that the trait is dominant.

In general, the best evidence for a dominant trait would be consistent expression of the trait in the phenotype of individuals who carry at least one copy of the dominant allele. This can be observed through controlled breeding experiments and statistical analysis of the resulting offspring.

Explanation:

The evolution of the rock pocket mouse is a great example of how natural selection can lead to the adaptation of a species to its environment. The mutations that occurred on the Mc1r gene allowed some individuals of the population to have a different fur coloration than the rest of the population. This new fur coloration provided a selective advantage to the mice living in the darker volcanic rock environment.

The darker fur of the rock pocket mouse provided camouflage against predators, allowing them to blend in with the dark rocks and avoid being seen. This made them less likely to be preyed upon by predators such as owls and snakes, which hunt by sight. As a result, the mice with the darker fur were more likely to survive and pass on their genes to the next generation.

Over time, as the population of the rock pocket mouse continued to be exposed to predation, the proportion of individuals with the darker fur coloration increased. This is because the individuals with the darker fur coloration were more likely to survive and reproduce, passing on their advantageous traits to their offspring. Eventually, the population became dominated by individuals with the darker fur coloration, and the rock pocket mouse became a distinct species.

This process, in which mutations that provide a selective advantage become more common in a population over time, is known as natural selection. In the case of the rock pocket mouse, the mutations that occurred on the Mc1r gene allowed the mice to adapt to their environment and avoid predation, ultimately leading to the evolution of a new species.

Gametes are the sex haploid cells produced by a diploid germ cell through meiotic division. Parent 1) Gamete 1: W, gamete 2: W, gamete 3: W, gamete 4: W. Parent 2) Gamete 1: w, gamete 2: w, gamete 3: w, gamete 4: w.

Gametes are sex haploid cells (n) that result from meiotic division. During meiosis, a diploid germ cells divides into four haploid cell -the gametes-.

Each gamete carries half the genetic material of its parental cell. It contains only one of the alleles.

In the exposed example, we need to determine the parental gametes of two snapdragon plants concerning flower color.

Snapdragon plants express incomplete dominance for flower color, meaning that

First, we need to determine the parental genotype of a cross between a homozygous plant for white flowers with a homozygous plant for red flowers.

Parental 1: WW ⇒ White phenotype

Parental 2: ww ⇒ Red phenotype

The whole progeny resulting from this cross will be pink, Ww.

Now, we need to determine the parental gametes.

The germ cell is WW. This cell divides into four haploid cells carrying only one of the alleles. So,

Gamete 1: W

Gamete 2: W

Gamete 3: W

Gamete 4: W

The germ cell is ww. Repeating the same reasoning as before, this diploid cell divides into four haploid cells carrying only one of the alleles. So,

Gamete 1: w

Gamete 2: w

Gamete 3: w

Gamete 4: w

Now we can make the Punnett square representing the cross and using these gametes.

Parentals)  WW   x    ww

Answer:

Inherited disorders that are X-linked are passed down from parents to their children through the X chromosomes. Males have only one X chromosome, inherited from their mothers, and therefore only one copy of any X-linked disorder. In contrast, females have two X chromosomes, one inherited from each parent, and therefore have two copies of any X-linked disorder.

Because of this difference in the number of X chromosomes between males and females, the frequency of an X-linked disorder will vary between the two sexes. In particular, males will display the disorder with greater frequency than females. This is because males have only one copy of the disorder, and therefore will always display the disorder if they inherit it. In contrast, females may not display the disorder if they inherit a healthy copy of the X chromosome from one parent and a copy of the disorder from the other parent. Therefore, the correct answer is (B) Males would display this disorder with greater frequency than females.

A) Turkey feet grass

Explanation:

Grassland biome is one of the biomes that makes up the Earth's biosphere. Due to the characteristics of this biome (grassland), it favours the abundance of grass species over trees and shrubby plants. These characteristics include a low annual rainfall, soil's susceptibility to wind erosion etc.

Based on these characteristics, an organism that will thrive in this biome must be structurally adapted to it. This is the case of the Turkey feet grass mentioned in the question. The Turkey feet grass possess very deep roots to prevent soil loss in windy areas, and to help anchor the plant. This is as a result of soil loss common to the soil of grassland biomes.

The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.

Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.

While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

The symptoms of anorexia nervosa and bulimia nervosa overlap at a large extent. Both are eating disorders in which the individual, affected by any of those, tries to lose weight in unhealthy manner. But there are some key differences between both the disorders.

People suffering with anorexia tend to reduce their food intake to lose weight. It includes extreme dieting and in some cases people stop eating or eat minimal.

People with bulimia continue to eat. Unlike people with anorexia they binge, or overeat large amount of foods. The repetitive cycles of binge-eating lead to self-induced vomiting or starvation which further leads to weight loss.

Whereas excessive exercise is common in both the disorders.

One difference between anorexia nervosa and bulimia nervosa involves  The amount of food that is typically consumed.

What is anorexia?

The eating disorder anorexia nervosa is marked by weight loss (or inadequate weight gain in growing children), difficulty maintaining a healthy body weight for one's height, age, and stature, and, in many cases, a deformed perception of one's own body.

People of all ages, genders, sexual orientations, races, and ethnicities are susceptible to anorexia. For hundreds or thousands of years, historians and psychologists have discovered evidence of people exhibiting anorexia symptoms.
