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.

1. What is the major source of energy for the brain

Answers

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.

If you cross two organisms that are heterozygous for a trait, what percent of
the offspring would you expect to express the recessive phenotype?

Answers

Answer:

25%

Explanation:

Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.

An advantage of having a set of criteria for defining mental disorders is that it offers a framework and terminology that can be shared among researchers and doctors. It involves defining mental disorders.

A mental disorder is any condition that causes distress and/or impairment of individual functioning, thereby affecting mental health and wellbeing.

The standardized systems represent systematic classification procedures whose objective is to define mental disorders in order to be systematically used by healthcare facilities and scientific research.

The most widely used and accepted standardized systems include the 'International Statistical Classification of Diseases and Related Health Problems' and the 'Diagnostic and Statistical Manual of Mental Disorders'.

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.
