Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?
Answers
Answer:
There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?
A. Biome
B. Community
C. Ecosystem
D. Habitat
Answers
Answer:
habitat
Explanation:
The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.
What is a habitat?
A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.
Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.
So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of interacting biotic and abiotic factors in an area
Thus, the correct option is D. Habitat.

Which statement best explains why these siblings are genetically different from each other?
A.One chromosome from each pair randomly passes to the sex cells during meiosis and leads to differences between the siblings.
B.One chromosome from each pair randomly passes to the sex cells during fertilization and leads to differences between the siblings.
C.Mutations occur during meiosis and lead to differences between the siblings.
D.Mutations occur during fertilization and lead to differences between the siblings.
Answers
Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.
Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.
Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.
During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.

Answers
Answer:
C.
Explanation:
Please do brainless :)
Mountain breeze refers to the fact that the surface breezes are coming from the mountain and blowing into the lowlands. Thus, option C is correct.
What is the movement of air in mountain breeze?The air cools during the night and flows into the valley from the mountainside.
As a result, the breeze blows in the other direction; it travels from the mountains to the plains and valley floor. This wind is therefore referred to as the mountain breeze.
As the air rushes in to fill the space, the air pressure decreases and a gust of wind is produced. A valley breeze, on the other hand, develops when cooler air in the valley falls to fill the space left by the warm air rising.
Therefore, Mountain Breeze in which air move from high pressure to low pressure.

Stored chemical energy can be used immediately and is released in the mitochondria.
Answers
Answer:
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. The energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
So the answer is Stored chemical energy is broken down and released in the mitochondria.
Explanation:
In cellular respiration, stored chemical energy is broken down and released in the mitochondria. The correct option is B.
What is mitochondria?Mitochondria are the membrane-bound organelles that create the maximum of the chemical energy necessary to power the biochemical reactions of the cell.
The mitochondrial energy is stored in a small molecule referred to as adenosine triphosphate (ATP).
Cellular respiration is the way by which organic fuels are oxidized in the presence of an inorganic electron acceptor, encompassing one as oxygen, to give enormous amounts of energy and pressure the majority production of ATP.
Cellular breathing is the way by which cells in plants as well as animals break down glucose and convert it into power, which is then used to perform work.
The goal of cellular respiration is simple: to provide the energy that cells require to function.
Thus, the correct option is B.

List the angles in order from smallest to largest. Note image in not drawn to scale
Answers
Using sine rule and cosine rule, the angles from smallest to largest is A,B,C.
Using the cosine rule;
a^2 = b^2 + c^2 - 2bc cos A
When;
a = 9 cm
b = 16 cm
c = 18 cm
9^2 = 16^2 + 18^2 - (2 × 16 × 18) cos A
81 = 256 + 324 - (576) cos A
81 = 580 - 576 cos A
81 - 580 = - 576 cos A
cos A = (81 - 580)/ - 576
A = cos-1[(81 - 580)/ - 576]
A = 30°
Using the sine rule;
a/sin A = b/sinB
asinB = bsinA
sinB = bsinA/a
B = sin-1(bsinA/a)
B = sin-1[(16 × sin30)/9]
B = 63°
Now;
A + B + C = 180(Sum of angles in a triangle)
C = 180 - ( A + B)
C = 180 - ( 30 + 63)
C = 87°
The angles are A, B, C.
