Different types of selection may occur within a species in response to environmental change. Which of the following would provide evidence that stabilizing selection is occurring in response to environmental conditions?

A shift in a population's frequency curve from an intermediate phenotype to an extreme phenotype
A shift toward equal distribution of all phenotype frequencies, including intermediate and extreme phenotypes
An increase in the frequency of extreme phenotypes and a decrease in the frequency of intermediate phenotypes
An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes

Answers

Answer 1

An increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes favors stabilizing selection. Therefore, the correct statement is option D.

What is stabilizing selection?

Stabilizing selection is a natural selection favoring intermediate phenotypes over extreme phenotypes. When the environment is stable, individuals with intermediate traits will be more fit than those with extreme traits.

Individuals with intermediate phenotypes have high chances of survival due to stabilizing selection, resulting in an increase in the frequency of intermediate phenotypes and frequency of extreme phenotypes decreases.

Stabilizing selection results in reduction of the genetic variation within a population, as extreme phenotypes are less likely to survive.  The reduction in genetic variation results in more homogeneous population.

Therefore, an increase in the frequency of intermediate phenotypes and a decrease in the frequency of extreme phenotypes is a type of stabilizing selection.

Which would be true of sexual reproduction?

a
increases survival rate
b

c
increases genetic diversity
d
produces identical offspring

Answers

Answer:

c increases genetic diversity

Explanation:

Answer:

C. increases genetic diversity

Explanation:

First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

by the data if...

A. traits independently assorted in

B. the traits for white fur and red eyes were
always inherited together.

C. all the F1 offspring had the same phenotype.

Answers

Answer: B

the traits for white fur and red eyes were always inherited together.

Explanation:

The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.

What is law of independent Assortment?The law of independent assortment selects alleles of two extra genes into gametes independently of each other.The allele acquired for one gene is unrelated to the allele obtained for another.Mendel's experiment constantly shown that the progeny's distinctive combinations are always unique from their parents'.He formulated the Law of Independent Assortment on this premise.

So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

Based on one of the four scenarios below, create an explanation for how Natural selection works, incorporating all of the 5 concepts that contribute to it.

1. Galapgos Darwin's Finches

2. Caribbean Anoles

3. Giraffe lab

4. In a field that is mostly green because of regular rain, the coat color of the mice species that lives there is mostly dark colors. Over a period of 10 years, there is a drought, and the grass has a lot more dead material, making the field have a much lighter over all color. What happens to the population of mice (coat colors) and why?

5. Make up your own scenario (tell me it) and then describe how natural selection would take place with changes.

Answers

Answer:

Population of mice having dark coat colors decreases by changing of features of natural selection.

Explanation:

The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.

humans?

A)malaria and ebola

B)sickle cell anemia and malaria

C)cytochrome c disease and plasmodium fever

D)iron-deficient anemia and yellow fever

Answers

Answer:

sickle cell anemia and malaria

Explanation:

Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.

The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.

What is sickle cell mutation?

The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.

The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.

Which 3-carbon molecule is one of the final products of glycolysis? (1 point)
oxaloacetic acid
NAD+
O pyruvic acid
O ADP

Answers

Answer:

pyruvic acid

Explanation:

Glycolysis involves the breaking of glucose molecule into two molecules of a 3-carbon compound called pyruvate (pyruvic acid) & two other molecules of ATP

Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Thus, option C is correct.

What is the significance of glycolysis?

Glycolysis is the metabolic process by which glucose produces cellular energy, glycolysis is significant.

The most crucial source of energy for all living things is glucose. Most cells in the human body prefer glucose as a fuel because red blood cells cannot use anything else.

Most living things engage in some form of glycolysis. It represents the initial phase of cellular respiration.

It is a glycolysis route that results in the partial conversion of pyruvate from glucose. The common mechanism for both aerobic and anaerobic respiration is glycolysis.

Therefore, pyruvic acid is a 3-carbon molecule which is the final products of glycolysis.
