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.

Since we can't drink ocean water due to its salt content, why is polluting the oceans so much a concem for people? Write your response in the essay box below.
answer:
we can't pollute water because there are creatures and organisims that live in the water so if we pollute it then they will die, besides you can filter the water to get rid of salt then you're able to drink the water and also use it for many other purposes.
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.

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

5. One of the most important steps to achieve a more sustainable future is to reduce a. Water conservation b. Overconsumption c. Population growth d. Both B and C
Answer:
B.
*Read the explanation plz
Explanation:
A actually increases sutainability, and C is just wrong. It's technically saying that we should not let humans be born, we shouldn't let people get pregnant, which of course no one is gonna listen to. So B is right because if we consume too many things, the next generation won't have as many resources as they need to survive.

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.
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.

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.
In which stage of mitosis do chromosomes first appear?
A
prophase
B
metaphase
anaphase
D
telophase
Answer:
Hi, there
Prophase
Prophase is the first stage in mitosis, occurring after the conclusion of the G2 portion of the interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.

Pls answer quick
Answer:
Fungi
Explanation:
Fungi (such as mushrooms) are eukaryotic and multicellular. They are decomposers, which means they feed on dead and decaying organisms. If the question was only asking for one that feeds on dead and decaying organisms, the answer could also be bacteria, for they are also decomposers, but bacteria are prokaryotes and unicellular.

why animals need to move quickly
Answer:
Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.
