Answer:b

No mitochondria,anaerobically

Explanation:

The red blood cells have no mitochondria and generate energy anaerobically.

The red blood cell gets energy carrier ATP from glycolysis of glucose or lactic acid fermentation. Both of these process occur in cytoplasm.

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children

vova2212 [387]

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

║ A ║O

O║AO║OO

There is a 50% of probability of having O offsprings with AO and OO.

║ A ║A

O║AO║AO

O║AO║AO

With AA and OO, the probability is 0%

║ A ║O

A║AA║AO

O║AO║OO

With both parents having AO, blood the probability of having a OO offspring is 25%.

In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.

The reason for the change in the hands of the chimpanzee include:

Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
Sexual reproduction ( Doesn't represents a reason for the change)
Differences in enhancer sequences( Represents a reason for the change).

<h3>What is mutation?</h3>

Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:

When there is spontaneous break down of deoxyribonucleic acid (DNA).
Change in a single nucleotide of the DNA.
when there is additions or deletions of nucleotide in a DNA strand.

A change can be noticed in an animal such as Chimpanzee when the following occurs:

Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.

Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

Anastasy [175]

In cardiac muscle

a. an action potential spreads throughout the Z discs.

b. intercalated discs connect the muscle fibers together.

c. calcium enters the cell from storage chambers called intercalated discs.

d. potassium is released from the sarcoplasmic reticulum

Answer:

b. intercalated discs connect the muscle fibers together.

Explanation:

Intercalated discs are components of the muscles found in the heart(cardiac muscles).

Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.

Intercalated discs are made of up desmosomes and gap junctions.

Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.

the correct order of events in the nutritional processing of this food is ingestion- digestion- absorption- egestion.

Explanation:

1.) Ingestion involves taking food, drink, or another substance into the body by swallowing to aid in digestion.

2.) Digestion involves the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.

3.)Absorption involves the in take of the digested food into the bloodstream

4.) Egestion involves the removal of undigested food substance from the body.
