Answer:
Following are the responses to the given question:
Explanation:
Increased [tex]CO_2[/tex] gases in the water may hasten photosynthesis, enabling crops to develop and grow more quickly. Some [tex]CO_2[/tex] is absorbed and more oxygen is expelled as the frequency of rate of photosynthesis.
The higher plants grown means greater water filtration. Natural selection will run its course if the water is less polluted, as well as the fish may not need to pass mostly on full-body plate characteristics to their descendants.
Which type of reproduction provides organisms with the following disadvantages? Organisms must grow until mature enough to produce sex cells. Finding a mate uses energy and takes time.
A. Asexual Reproduction
B.Sexual Reproduction
Answer:
The answer is B.
Explanation:
Sexual reproduction is a type of reproduction in which you have to find a mate of the same species to reproduce.
Describe why certain traits increase in frequency in a population. Provide ONE example to support your response.
Answer:
When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
Explanation:
Because of having dominant traits certain traits increase in frequency in a population because they have.
What are traits?A phenotypic trait is a specific variant of an organism's observable characteristics. Phenotype refers to any measurable, observable and obvious characteristics of an organism. It can be either hereditary or environmental, but usually occurs as a collection of both.
When any allele tends to determine the phenotype, when passed from parent to child, it called as dominant allele. In case of homzygosity as well as heterozygosity, dominant allele can express itself.
Recessive in contrast is, when genotype is homozygous, the trait expressed is referred to as recessive trait. Therefore, certain traits increase in frequency in a population.

What is cell theory ?According to the cell theory,
Cells make up every living thing. They can be either unicellular or multicellular in nature.The simplest form of life is the cell.Existing cells give rise to new ones. They are not the result of spontaneous generation.Eukaryotes are thought to have developed from prokaryotes approximately 2.7 billion years ago. The main difference between these two types of creatures is that eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells have not.
Therefore, option (C) is correct because prokaryotes are the simplest cellular organism while eukaryotes are complex multicellular.

2. What nutrients do you need to stay alive? How do you obtain them?
Answer:
Explanation:Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.

Among Delta-back stripped fish, there are two genes that segregate independently of one another. Suppose the alleles at the first locus are A (dominant) and a (recessive) and the alleles at the second locus are B (dominant) and b recessive). If an AABB fish mates with an aabb fish, and their offspring are inter-crossed, the proportion of F2 fish that show a recessive phenotype at the first locus and a dominant phenotype at the second is:
Answer:
4/16
Explanation:
It is given that the alleles of the first locus = A dominant and recessive a
The allele of the second locus = B dominant and the recessive b.
Now if fish with AABB mates with the aabb fishes, then to tell the proportion of the F2 fish which shows either the dominant phenotype at the [tex]$\text{first locus}$[/tex] and also a recessive phenotype at the [tex]$\text{second locus}$[/tex].
So for this, the recessive phenotype at the [tex]$\text{first locus}$[/tex] as well as the recessive phenotype at the [tex]$\text{second locus}$[/tex] is in the ratio of 4/16.
Which organ system gives instructions to the muscular system and the circulatory system during exercise?
Answer:
Nervous system
Explanation:
The nervous system can be divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The autonomic nervous system is a part of the PNS which is concerned with the control of involuntary physiologic processes. During the exercise, the sympathetic nerves of the autonomic nervous system are in charge of preparing the body for physical activity by increasing the respiration rate, heart rate and blood pressure. The sympathetic nerves can also increase energy for the muscles by reducing insulin release and increasing blood glucose.

12. Where is the rate of primary production the lowest?
a. upwelling along coasts
b. in the middle of the current gyres
c. along the Equator
d. around Antarctica in the summer
e. coasts
Answer:
Option B, in the middle of the current gyres
Explanation:
The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.
Hence, option B is correct

Explain why sweat accumulates on a person's skin in a hot humid
Environment
Answer:
In humid conditions where surrounding air cannot hold further water vapour, sweat evaporates slowly, if at all. As a result the body heats up. it is difficult for the sweat to evaporate and in high humidity conditions we tend to sweat more. This explains why it feels so much hotter in high humidity.

The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.
The attack by snakes is acting as a selective pressure on the frogs´ population. It is an ecological pressure that is modeling the frogs´ phenotype.
Animals that suffer more attacks are the blue ones, followed by green and red frogs. Those that suffer the fewest number of attacks are the yellow individuals.
So natural selection will be acting on this population favoring the alleles that code for yellow color. Genes that express yellow color increase more the frogs´ fitness than genes that code for the other colors. So natural selection increases the frequency of genes coding for yellow color and will decrease the frequency of the other alleles. Probably the less favored will be genes that express blue.
