blagie [28]

Answer:

Increase in eosinophils.

Explanation:

The leukocytes are the white blood cell that plays an important role in the immune system. The white blood cell include eosinophil, basophil, neutrophil and monocytes.

The allergic reactions that are caused by hay fever or asthma is marked by the excess increase in the number of eosinophils in the body. The eosinophils are the first to reach at the site of parasitic infections and protect the body during the allergic reactions.

Thus, the answer is eosinophils.

Veronika [31]

<u>Answer:</u>

Option (C)

There is no change in mass during a chemical reaction;

<u>Explanation:</u>

The law of mass conservation can better explain this phenomenon. According to the rule, "Energy can not be either produced, nor can it be lost."

In simpler terms, the total masses of all substance involved in a chemical reaction are same. Furthermore, the total atoms on either sides, i.e., reactant side and product side are the b.

BabaBlast [244]

Answer:

The main function of the DNA polymerase is to synthesize DNA by the process of replication.

WILL MARK BRAINLIEST! (= 20 Points)
erastovalidia [21]

Answer:

1.Carbon dioxide is converted to sugar used for food. - 1. Location- A

2.Carbon trapped in fossil fuels is converted to carbon dioxide. - 2. Location- C

3.Organic carbon is converted to fossil fuels. -3. Location- E

4.Carbon dioxide is converted to carbonates.- 4. Location- D  

5.Sugar is broken down and converted to carbon dioxide.  - 5. Location- F

Explanation

1. Carbon dioxide is converted to sugar used for food: The carbon dioxide is converted into sugars by the process of photosynthesis, which occurs in the green plants. Plants trap carbon dioxide and sunlight from the atmosphere, to synthesize their food.

2. Carbon trapped in fossil fuels is converted to carbon dioxide: The fossil fuel produced deep inside the earth, acquired by the factory. From the factory the carbon dioxide liberated to the atmosphere.

3. Organic carbon is converted to fossil fuels: The organic carbon obtained after the degradation of organic matter is responsible for the synthesis of fossil fuels.

4. Carbon dioxide is converted to carbonates: The carbon dioxide from the atmosphere gets dissolved with water of the water body and termed as carbonic water.

5.Sugar is broken down and converted to carbon dioxide: The glucose or sugar as a source of food in plants gets broken down into carbon dioxide and water by the process of respiration.

Which of the following made cells unique protobionts?
Lelu [443]

Answer;

b. Their ability to pass on genetic information.

Explanation;

-Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure.

-They exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings.
