List the angles in order from smallest to largest. Note image in not drawn to scale
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.

Fraternal twins, while conceived at the same time, are not genetically identical.
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.
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.

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?
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 these forms when air moves in the directions shown by the arrows
in the diagram?
A ) Valley Breeze
B) Land Breeze
C ) Mountain Breeze
D ) Sea Breeze
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.

Which statement best describes energy release in cellular respiration? (1 point)
Stored chemical energy is broken down and released in the cytoplasm.
Stored chemical energy is broken down and released in the cytoplasm.
Stored chemical energy is broken down and released in the mitochondria.
Stored chemical energy is broken down and released in the mitochondria.
Stored chemical energy can be used immediately and is released in the cytoplasm.
Stored chemical energy can be used immediately and is released in the cytoplasm.
Stored chemical energy can be used immediately and is released in the mitochondria.
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.

1. What is the major source of energy for the brain
Explanation:
glucose
The mammalian brain depends on glucose as its main source of energy. In the adult brain, neurons have the highest energy demand [1], requiring continuous delivery of glucose from blood.
hope its helpful to you #
The major source of energy for the brain is glucose. Metabolism of glucose provides energy to the brain.
What is the brain?The brain is a body part that operates the various functions of the body. It is present in the head of the body. It is divided into two parts, the left brain, and the right brain.
Energy is something that is produced by the metabolism of food. Energy7 is required to carry out all the processes of the body. To walk, run, work, eat, everything requires energy.
The main source of the energy in animals and plants is glucose. The food we eat converts into energy by the process of respiration. The energy is transported into all parts of the body by blood circulation.
Thus, glucose is the major source of energy for the brain.
