Answer: 1. Repair and Maintenance

Protein is termed the building block of the body. It is called this because protein is vital in the maintenance of body tissue, including development and repair. Hair, skin, eyes, muscles and organs are all made from protein.

2. Energy

Protein is a major source of energy. If you consume more protein than you need for body tissue maintenance and other necessary functions, your body will use it for energy. If it is not needed due to sufficient intake of other energy sources such as carbohydrates, the protein will be used to create fat and becomes part of fat cells.

3. Hormones

Protein is involved in the creation of some hormones. These substances help control body functions that involve the interaction of several organs. Insulin, a small protein, is an example of a hormone that regulates blood sugar. It involves the interaction of organs such as the pancreas and the liver. Secretin, is another example of a protein hormone. This substance assists in the digestive process by stimulating the pancreas and the intestine to create necessary digestive juices.

4. Enzymes

Enzymes are proteins that increase the rate of chemical reactions in the body. In fact, most of the necessary chemical reactions in the body would not efficiently proceed without enzymes. For example, one type of enzyme functions as an aid in digesting large protein, carbohydrate and fat molecules into smaller molecules, while another assists in the creation of DNA.

5. Transportation and Storage of Molecules

Protein is a major element in transportation of certain molecules. For example, hemoglobin is a protein that transports oxygen throughout the body. Protein is also sometimes used to store certain molecules. Ferritin is an example of a protein that combines with iron for storage in the liver.

6. Antibodies

Protein forms antibodies that help prevent infection, illness and disease. These proteins identify and assist in destroying antigens such as bacteria and viruses. They often work in conjunction with the other immune system cells. For example, these antibodies identify and then surround antigens in order to keep them contained until they can be destroyed by white blood cells.

Answer:

Sí, ya que su función es matarlas o impedir que aumente el número de estas.

Explanation:

Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.

Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.

The cell cycle is an essential process of growth and function. It has many phases which divide the genetic material and the cytoplasmic organelle equally into new cells. The cell cycle is crucial for survival.

Option 1) Mitochondrial DNA released into the cytoplasm is the process that does not occur in the animal cell cycle.

Therefore, mitochondrial DNA is not discharged into the cytoplasm.

The death rate of the mouse population is significantly affected by the overpopulation of its predators like cats, owls, snakes, etc.

The Population may be defined as a group of individuals belonging to the same species living in the same area at a given time period of time.

According to the context of this question, if the number of predators of the mouse population is higher than that of the mouse, the death rate is generally found to be higher.

While if the population of the predator is low, as compared to the mouse, then the death rate is probably less. Other factors like space, food, mating partners, etc. may also describe the death rate of any species.

Therefore, the death rate of the mouse population is significantly affected by the overpopulation of its predators like cats, owls, snakes, etc.

Explanation:

It doesn’t matter where u take ur observations

The statement which is not important in an experiment is to perform the experiment in the same location where the observations were done in. Thus, the correct option is D.

An experiment may be defined as a scientific procedure that should be followed in order to estimate, discover, and observe a given testable hypothesis to demonstrate a valid and accurate conclusion.

The Scientific experiments should also be performed under a controlled environment where all data must be recorded and keep them consistently.

In demonstrating the valid outcome of any scientific experiment, it is required to alter only one source of variable and estimate the value of others on the basis of it.

Therefore, the statement which is not important in an experiment is to perform the experiment in the same location where the observations were done in. Thus, the correct option is D.

Answer:

Explanation:

The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism. The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.

The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water.

These same molecules can serve as energy sources for the glucose pathways.
