Which statement describes natural selection
Answer: You didn't put any statements lol
Explanation:
But basically natural selection is when organisms with the most favorable traits will survive and reproduce. (ex. there are 2 strains of bacteria - one that resists antibiotics and one that doesn't. The one that resists the antibiotics will strive and reproduce because that will be the more favorable trait that will be able to be inherited by future generations.)
Can someone help me with this question, please!!
Answer:
Genotypic- 1:1
Phenotypic- 1:1
Explanation:
For this problem, I will use the letter A to represent the alleles. The first parent's genotype would be Aa, and the second parent would be aa. Then, using a punnet square to cross the two parents the outcome is Aa, Aa, aa, aa. This means there is a 50% of a mixed individual and a 50% of a purebred recessive. Both phenotypes also have a 50% chance of being expressed. Since the percentages are equal both ratios are 1:1.
A dichotomous key uses the _________ characteristics of organisms for identification purpose.

How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.

A man with homzy type A blood and a woman with heterozygous type B blood want to know the probability of having a child with type AB blood.
Answer:
[tex]\frac{1}{2}[/tex]
Explanation:
Homzy. type A blood = AA
Heterozygous type B blood = Bb
Punnett square
| B | b
A | AB | Ab
A | AB | Ab
The ratio is = 2:2 = 1 : 1
The total number of outcomes are 4
The number of AB are 2
Thus the probability is [tex]\frac{2}{4} = \frac{1}{2}[/tex]

If the allele for an attached earlobe (e) is recessive to the allele for an unattached earlobe (E), what will be the relative frequency of e in a population?
a. It could be more or less frequent than T.
b. It could only be equally as frequent as T.
c. It could only be more frequent that E.
d. It could only be less frequent than T.
Answer:
It could be more or less frequent than T.
Explanation:
As demonstrated by the Hardy-Weinberg principle, the dominance or recessiveness of an allele does not determine its frequency in a population.
In the given scenario, the relative frequency of e in a population will be It could be more or less frequent than T. The correct option is a.
What is allele?An allele is one of two or more DNA sequence versions at a given genomic location. For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent.
The Hardy-Weinberg principle demonstrates that an allele's dominance or recessiveness does not determine its frequency in a population.
Thus, the correct option is a.

How does population growth differ between developing countries and developed countries? What might account for these differences?
Answer:
Developing countries have a low life expectancy because things like water might be populated/scarce, the air may be polluted and immunisation might not be possible. But developed countries are more likely to have safe drinking water, and vaccines.

How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.
Write the definition you have of The Law of the Conservation of Energy (don’t cut and paste):

All of the following can take material into cells except
O active transport
O exocytosis
O endocytosis
O passive transport
Answer:
The correct answer is - exocytosis.
Explanation:
All of the given options of the transport mechanism are the transport of the substances either into the cell or out of the cell or both. Active transport is the transport mechanism that involves the transports of substances from the lower concentration region to the higher concentration region and utilize energy.
Endocytosis and exocytosis are the forms of active transport, however, endocytosis involves taking material into the cell and exocytosis out of the cell. Exocytosis is the form of active transport as it requires energy to moving materials from within a cell to the exterior of the cell.

Define the following :
-self-concept
-self motivation
-volunteer
-self-image
-Adolescents
Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities. When we speak of self-image we refer to the image that our subconscious has of ourselves. Adolescence is understood as the period of human development after childhood and before adulthood, in which the biological, sexual, social and psychological changes necessary to form a socially mature individual and physically prepared for reproduction take place.

Do you think that government should institute measures to control the human population? Give me your honest opinion please:)!
Answer:
Although I think the human population does need to be slowed down, I do not think it is right for any government on earth to try and control it. That is like trying to play God and I don't think that's right.
Explanation:
.
Answer:
Look below.
Explanation:
Personally I say it is a two way anwer a yes and a no (mostly no). A yes because if their is a carrying capacity for a state or area, it obviously needs to be controlled to avoid problems such as food shortages. A no because the govt is "weird" (my opinion dont come at me). This whole virus suspiciously just appeared. I speculate that this virus was manipulated by the government to control the human population. I could be totally wrong but this could be a possibility to control man kind. So yes government should institute measures to control the human population, if its under understandable circumstances. And a no if the government does it without human kind knowing and hurting the population to decrease vastly.

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution
Answer:
Cytochrome c is known to play a role in the electron transport chain and cell apoptosis. However, a recent study has shown that it can also act as an antioxidative enzyme in the mitochondria; and it does so by removing superoxide (O2–) and hydrogen peroxide (H2O2) from mitochondria.Therefore, not only is cytochrome c required in the mitochondria for cell respiration, but it is also needed in the mitochondria to limit the production of O2– and H2O2.
