Which statement describes the blood type of a person with the alleles IAIB? It is type AB because A and B exhibit incomplete dominance. It is type AB because A and B are codominant. It is type O because A and B are codominant. It is type A because A and B exhibit incomplete dominance.

Answers

Answer 1
Answer:

It is type AB because A and B are codominant.

Explanation:

It is the existence or the absence of the type of proteins such as A and B decides the type of blood in a person. These proteins A and B are present on the cells surface of red blood. The presence of two combo of A and B results in the four type of blood such as Type A, Type B, Type AB and Type O. In Type A blood the proteins that is present is only A. In Type B the B protein is only present. In Type AB, the proteins present are A and B. In Type there will be neither presence of A nor the presence of B.

The genotype is responsible for the generation of the type of blood. These genotypes,  iAiA or Iai produce type A protein. The genotypes iBiB or iBi  produce type B proteins. The genotype iAiB  produce the proteins A and B. ii genotype produces type O protein.

Answer 2
Answer:

Answer:

It is type AB because A and B are codominant.

Explanation:

Both A and B are dominant, O is recessive.

A plant without enough water may wilt and close its stomata (leaf openings). This decreases the rate of photosynthesis because _____.

Answers

the plant no longer is allowing the necessary carbon dioxide required for photosynthesis to enter through the stomata. The plant also needs to be able to release oxygen,the byproduct of photosynthesis through the stomata. The stomata are also responsible for theamount of water inside the plant. By closing when there is not enough water, the stomata prevent loss of additional water due to evaporation.

A plant without enough water may wilt and close its stomata (leaf openings). This decreases the rate of photosynthesis because chloroplasts don't have acess to the sunlight.

How many moles of oxygen are needed to burn 1.33 moles of methyl alcohol (CH3OH)? 2CH3OH + 3O2 2CO2 + 4H2O

Answers

Well, it takes 3 moles of oxygen to completely burn 2 moles of methyl... 

So for every 2 moles of methyl, you need 1.5 times as much oxygen (3 divided by 2) 

That makes your ratio 1 : 1.5 

You need 1.33 moles of methyl so you multiply both sides of the ratio by 1.33 = 1.33 : 1.995 

 1.995 moles of oxygen are needed

Answer:

A.  0.877 moles

B.  0.997 moles

C.  1.330 moles

D.  1.995 moles

E.  2.660 moles

Which option is a balanced equation for cellular respiration?

Answers

The answer is; B

C6H12O6+6O2→6CO2+6H2O+36ATP

In respiration, glucose is broken down to produce ATP that is the energy currency of the body. The process of respiration occurs in three processes; the pyruvate cycle, the Krebs cycle, and oxidative phosphorylation.  Water and ATP are the ultimate products in the biochemical process of breaking down glucose molecules. Oxygen is consumed. The equation has to be balanced on both sides due to the rule of conservation of matter in thermodynamics.


C6H12O6 + 6O2 -> 6CO2 + 6H2O

Choose the best answer that describes what is happening during the process of mitosis. the stage during which the cell carries out normal cellular functions, and makes copies of its DNA.

the stage of the cell cycle during which the cell's nucleus and nuclear material divide.

the method by which a cell's cytoplasm divides, creating a new cell.

Answers

Answer;

The correct answer would be the stage of the cell cycle during which the cell's nucleus and nuclear material divide.

Mitosis or M-phase is one of the phases of cell cycle in which nucleus and its content (genetic material)  divide into two daughter cells.

It sub-divided into various stages namely prophase, metaphase, anaphase and telophase.

Prophase:

  • Chromosomes are condensed by the end of this phase.
  • Spindle fibers grows and attach to the kinetochores of the chromosomes.
  • Nuclear envelope, nucleolus and other organelles disappear.

Metaphase:

  • All the chromosomes are aligned at the center of the cell forming the metaphase plate.
  • Two kinetochores of each chromosome are attached to the microtubules of opposite spindle poles.

Anaphase:

  • Sister chromatids are separated and pull towards opposite poles.
  • The cell elongates.

Telophase:

  • Cell continues to elongate.
  • Nuclear membrane and nucleolus reappear forming two daughter nuclei each with a set of chromosome.
  • Chromosome decondense to form chromatin.

It is followed by cytokinesis which results in the formation of two daughter cells.

The Krebs cycle is considered a cycle because?

Answers

While the Krebs Cycle does not use oxygen directly it does need oxygen to accept the hydrogen ions after they've participated in the electron transport chain. So this makes it an aerobic process.
