Answer:
Origin
Explanation:
Chromosomal mutations are changes in the normal structure or number of chromosomes. Changes in chromosome structure can result from errors in meiosis or from exposure to radiation or other damaging agents. Certain changes in chromosome number can result from nondisjunction during either meiosis or mitosis. Both structural mutations and nondisjunction can play a role in trisomy 21, commonly known as Down syndrome.
Answer:
Yes.
Explanation:
Yes, both structural mutations and nondisjunction can play an important role in trisomy 21 which also called down syndrome. In this type of syndrome, extra copy of chromosomes is present in the cell. Down syndrome is a genetic disorder that causes various defects in the children such as learning problems, facial features, vision and hearing problems.

Fossils of canines were found on opposite sides of a mountain range. The fossils are from species that are anatomically similar, but the climates were extremely different on each side of the range. Which type of evidence for evolution do these fossils exemplify?
A. vestigial structures
B. analogous structures
C. coevolution
D. biogeography
The phenomenon described in the question is an example of coevolution.
What is coevolution?Evolution refers to the changes that occur in organisms as they metamorphose from one form to another over a given time interval. The changes that occur in one specie usually affects the changes that occur in related species. This is known as coevolution.
Hence, if fossils of canines were found on opposite sides of a mountain range and they belong to species that are anatomically similar, but the climates were extremely different on each side of the range, it is an example of coevolution.

What does one newton exerted over a distance of one
meter equal?
Answer:
One Joule.
Explanation:
One newton exerted over a distance of one meter equal to one joule.
Joules is the S.I unit used for the measurement of scientific quantities such as work and energy and it was named after the prominent English physicist, James Prescott Joule.
Given the following data;
Force = 1N
Distance = 1N
Therefore, we know these parameters or quantities are directly related to work.
Mathematically, work done is given by the formula;
Work done = force * distance
[tex] W = F * d[/tex]
Where,
W is the work doneF represents the force acting on a body. d represents the distance covered by the body.Substituting into the equation, we have;
[tex] W = 1 * 1[/tex]
Work done = 1 Joule.

Species can change over time and adapt to their environment.
A. True
B. False
Answer:
True
Explanation:
This statement is true. A species can always change over time and adapt to their environment.
What are species?A species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. It is a class of plants or animals whose members have the same main characteristics and are able to breed with each other.
Moreover, it is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behavior or ecological niche.
Hence, species can change over time and adapt the conditions according to their environment.

A track and field coach is trying to decide what beverage is the best pre-training beverage for athletes to drink before a daily training session. The coach has chosen three beverages: a soda, a Gatorade, and water for the athletes to drink before training. The coach will then collect data on their performance during the period of time while training.
Afterward, the coach will track the performance of the athletes over an eight week period to see how their performance has changed.
What is the best Hypothesis for the experiment above? Explain why that is the best Hypothesis.
Answer:
The correct answer is - "which beverage would help athletes the best if he takes it before a daily training session".
Explanation:
The coach is trying to decide which beverage is going to help best for the athletes before their training session. He tried soda, water, and Gatorade and compare the data he gets after his experiment.
According to his experiment, he wanted to find the best beverage that will help athletes best. For this, the best hypothesis would be "which beverage would help athletes the best if he takes it before a daily training session", as it provides the real idea of the experiment.
All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?
a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.
Answer: b
Explanation:
Camels ears are lined with fur to keep out sand and other blowing matter
The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.
What camels are adaptations for heat and dehydration?Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.
Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.
Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

bond forms between a hydrogen atom with a partial positive charge on one
molecule and another atom, such as oxygen, with a partial negative charge on an adjacent molecule.
Answer:
Due to difference in the values of electronegativities.
Explanation:
A covalent bond is formed between hydrogen atom with a partial positive charge on it and another atom, such as oxygen, have a partial negative charge on an adjacent molecule. This is because of the difference in the values of electronegativities. The hydrogen atom has lower electronegativity value as compared to oxygen so the shared pair of electron is slightly attracted by oxygen atom towards itself and formed partial positive charge on hydrogen and partial negative charge on oxygen atom.

Ion pumps and phagocytosis are both examples of
________.
a. endocytosis
b. passive transport
c. active transport
d. facilitated diffusion
Answer:
A
Explanation:
EDGE2021
Ion pumps and phagocytosis are both examples of active transport. Therefore, the correct option is C.
The movement of molecules or ions across the cell membrane against a gradient of concentration, from an area of lower concentration to an area of higher concentration, is called active transport. In this whole process energy must be used in the form of ATP (adenosine triphosphate).
Ion pumps are membrane proteins that actively transport ions across the concentration gradient across the cell membrane. These ions include sodium, potassium, calcium or hydrogen ions. The ion concentration imbalance required for many cellular functions is maintained by these pumps.
On the other hand, phagocytosis is a type of endocytosis in which cells engulf large molecules or solid particles and internalize them. Energy is required for the formation of pseudopods and for the solubilization of substances in the phagosome inside the cell.
Therefore, the correct option is C.

Which of the following is not a step of Natural Selection?
Overpopulation
Survival of the Fittest
Underpopulation
Variation
Answer:
im pretty sure it is underpopulation.
Answer:
I think it's B. survival of the fittest since it's mostly just a phrase people say. I don't think underpopulation because, I'm pretty sure that's used when there not enough of an animal in an area, so while it could be the answer I don't think it is. And overpopulation is used when there's to much of an animal in an area so like with underpopulation it could be the answer but I do not think it is. And Variation is a step in Natural Selection so that's definitly not it. So since Survival of the fittest is mostly just a phrase people say I think that's the answer. Sorry for wasting your time if I'm wrong.
