Answer:

Their similarity

Explanation:

Pharyngeal pouches are structures in vertebrates that develop in different parts of the body mainly in the face or neck. The similarity in their position and structural indicates a similarity . These structures provide evidence of evolution that the organisms evolved from the same ancestry.

MULTIPLE CHOICE

mojhsa [17]

Answer:

The correct answer is the growth of the offspring to adulthood.

Explanation:

A life cycle is illustrated as the stages of development, which take place during the lifetime of an organism. A life cycle ceases with the death of an organism. Generally, the animals and plants go through three fundamental stages in their life cycles, beginning as a seed or fertilized egg, developing into an undeveloped juvenile, and eventually turning into an adult.

During the stage of adulthood, a species will reproduce, forming a new generation. A life cycle can constitute more than three fundamental stages on the basis of the species. For example, the life cycle of a human being comprises five main stages.

Calculate the weight of an object of 30 kg on Earth. 2. Calculate the weight of an object of 30000 g on Earth. 3. Calculate the

Dima020 [189]

Answer:

1. 294N

2. 294N

3. 19.6N

4. 19.6N

5. 4.9N

6. 4.9N

7. 80N

8. 185N

Explanation:

The weight of an object is the force that gravity is having over it, and we measure it in <u>Neutowns (N), which equals Kg x m/s².</u>

To find the weight of an object, we use the formula F= m x g.

F stands for force, m for the object's mass, and g for gravity, which is the force that attracts objects to Earth, and we measure it by the acceleration that an object has during free falling.

<u>The Earth's gravity is 9.8 m/s²</u>

1. We use the formula F=m x g

F= 30kg x 9.8 m/s²

F= 294 N

2. We have to convert the 30000g into kg to use the formula

30000÷1000= 30kg

30000g equals to 30Kg, so the object's mass (m) is 30Kg.

F= m X g

F= 30kg X 9.8 m/s²

F= 294 N

3. F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

4.We have to convert the 2000g into Kg.

2000÷1000= 2Kg

The object's mass (m) is 2Kg.

F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

5. F= m X g

F= 0.5 kg X 9.8 m/s²

F= 4.9 N

6.We have to convert 500g to Kg.

500g÷1000=0.5Kg

The object's mass (m) is 0.5 kg

F= m X g

F= 0.5 Kg X 9.8 m/s²

F= 4.9 N

7. The gravity on the moon is different from the one on Earth. In the formula, instead of 9.8 m/s² for the gravity (g), we use 1.6 m/s².

F= m X g

F= 50Kg X 1.6m/s²

F= 80N

8. The gravity (g) on Mars is 3.7 m/s², so we have to use it in the formula where it says g to find the object's weight on Mars

F= 50Kg X 3.7m/s²

F= 185 N

Galina-37 [17]

Answer:

<h2>5.storage of energy</h2>

Explanation:

Proteins are important biomolecules that are a type of macromolecule.
This macromolecule is made up of a monomer that is called amino acid.
There are many functions of the protein molecules in living organisms.
They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
They also play an important role in the immune system.
The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.
