Why are cetacean are smarter than primates?
Answer:
well no duh we humans we smart and we invented half the stuff in the world
Explanation:
Answer:
Evolution and different environments.
Explanation:
Primates are intelligent in their own ways, such as motor control, the use of hands and feet simultaneously, control of both hands for different things at the same time.
Dolphins for example, however, they lack the limbs that primates do, so they don't need motor control as much as primates. They evolved to be very social animals, and that allows them to excel in groups while maintaining a pattern seeking brain much like primates, without the motor control capabilities.

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.

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

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.

A 20.0 gram sample of a certain radioisotope decays over a
period of 19.2 hours. After that time, only 2.50 g of the isotope
remains. Calculate the half-life.
quantity of the substance remaining = initial quantity of the substance * (.5)^(time elapsed/half life of the substance)
2.50 = 20 * (.5)^(19.2/x)
The half-life period of the given sample of the radioisotope is equal to 6.41 hours.
What is the half-life period?The half-life of a radioactive substance is defined as the time that is required to reduce the original quantity of a radioactive element to half after decay.
Half-life of a radioactive element is the characteristic of the element and does not depend upon the initial amount of the radioactive substance.
Given, the original amount of the radioisotope, N₀ = 20.0 g
The remaining amount of the radioisotope, N = 2.50 g
The time for which decay occurs, t = 19.2 hours
Consider that k is the rate constant of the decay of radioisotope,
[tex]k =\frac{2.303}{t} \times log \frac{N_0}{N}[/tex]
[tex]k =\frac{2.303}{19.2} log \frac{20}{2.50}[/tex]
k = 0.108 hr⁻¹
The half-life time of radioisotope can be calculated from the below mentioned formula:
[tex]t_{\frac{1}{2}} =\frac{0.693}{k}[/tex]
[tex]t_{\frac{1}{2}} =\frac{0.693}{0.108}[/tex]
[tex]t_{\frac{1}{2}} =6.41 hrs[/tex]
Therefore, the half-life period of the given sample of the radioisotope will be to 6.41 hours.

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.

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.
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.

Which description accurately describes the cell membrane?
a. a single permeable layer of phospholipids that have hydrophobic heads and hydrophilic tails
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
c. a single permeable layer of phospholipids that have hydrophilic heads and hydrophobic tails
d. a semi-permeable double layer of phospholipids that have hydrophobic heads and hydrophilic tails
e. a barrier of polypeptides that prevents molecules from entering or leaving the cell
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
