is the result of oxygen poor blood, which appears blue in veins.
A)Hemotosin
B)Methemeglobin
C)Hemolethoglobin
D)Blood Platelets

Answers

Answer:

The correct answer is - B) Methemeglobin.

Explanation:

Methemeglobin is a blood disorder due to the mutation in the hemoglobin which is known as the result of oxygen-less blood. In this disorder, the tissue did not get enough oxygen and appeared to be purple, or blue.

In this mutated form of hemoglobin iron atoms present in ferric instead of the ferrous state and therefore not able to bind with oxygen. It appears blue in veins and tissues look blue or purple.

Why is it important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high?

Answers

Answer:

These characteristics of water allows excellent working in the steam engines.

Explanation:

It is very important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high because due to large heat of vaporization, steam or vapors of water carries a huge amount of thermal energy. This large amount of heat energy is released when the steam condenses due to loss of kinetic energy. This property of water making it an excellent working fluid for heat engines as compared to any other fluid.

How are photosynthesis and cellular respiration related?

A. The products of photosynthesis are the reactants of cellular
respiration

B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.

C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.

D. Cellular respiration provides the energy for photosynthesis.

Answers

Answer:

I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.

Explanation:

Photosynthesis is  the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.

Answer:

A. The products of photosynthesis are the reactans of cellular respiration

Describe one type of factor that controls cell division.

Describe how damage to one of these factors can affect the cell division process.

Thanks!

Answers

The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.

Factors Affecting Cell Division
Nutrients. The nutrients present in the cell affect cell division. ...
Genetics. Genetic code regulates cell division. ...
Chemicals. Exposure to toxic chemicals such as pesticides and some cleaning chemicals can cause cell mutation. ...
Stress. Stress affects cell division.

Numerous cell cycle regulatory components, including cyclins, cyclin-dependent kinases (Cdks), and cyclin-dependent kinase inhibitors, regulate the cell cycle (CKIs).

What is a factor that controls cell division?

Positive cell cycle regulators cyclins and Cdks activate cell cycle components that are necessary for the beginning of the subsequent cell cycle phase.

The Influences on Cell Division Nutrients. Genetics: The nutrients in the cell have an impact on cell division. Cell division is controlled by genetic code and chemicals. Cell mutation can occur as a result of exposure to hazardous substances like pesticides and some cleaning products. Stress. Cell division is impacted by stress.

Therefore, numerous cell cycle regulatory components, including cyclins, and cyclin-dependent kinases Cdks.
