First let's take a look at the two squares close to the electron transport chain. As you can see, the two boxes are connected, which means there is some type of "conversion" occuring. Oxygen goes in and water comes out. (In other words, upper square = oxygen, lower square = water).

Now, the box that is far from the rest corresponds to the mithocondrial matrix of a mithocondrion, since we're talking about .

The two boxes connected to the ATP synthase are aso connected to each other, one going towards the ATP synthase and the other going out. Now, we just have to guide ourselves with logic. It's called "ATP synthase", which means the product will be ATP. So, ADP goes in and ATP comes out.

I think some ellimination would do good to answer this question. First of all, salmon contains a reasonable amount of B12 and iron and has high amounts of protein, of course. So options B., D. and E. are incorrect.

Nor salmon nor garlic butter contain fiber, so option A. is also incorrect.

Answer:

C.

Image 5 -

The Krebs cycle, the electron transport chain and respiration (aerobic) are closely related, because in anaerobic respiration we obtain oxygen, which functions as an electron acceptor in the electron transport chain, which produces NAD+ that is later used in the Krebs cycle to produce NADH and FADH2 that are used as electron carryiers in the ETC.

Answer:

C.

Hope it helped,

Humans have 46 chromosomes in each somatic cell. a. How many chromosomes does a child receive from its father? b. How many autos
GarryVolchara [31]

Answer:

Explanation:

<u>a. How many chromosomes does a child receive from its father?</u>

Every person receives half of their chromosomes from their father and half from their mother. For that reason, if humans have 46 chromosomes in each somatic cell, 23 of them come from the father.

<u> b. How many autosomes and how many sex chromosomes are present in each somatic cell? </u>

Each somatic cell has 46 chromosomes in total; of which 22 pairs are autosomes and 1 pair are sex chromosomes. Therefore, 44 chromosomes are autosomes and 2 chromosomes are sex chromosomes (the X and/or Y chromosomes).

<u>c. How many chromosomes are present in a human ovum? </u>

The human gametes (ovum in women and sperm cell in men) have half of a somatic cell's genetic material, so that when they combine in a zygote to create their child, they form an initial cell with 46 chromosomes in total. The ovum therefore has 23 chromosomes: 22 autosomes and 1 sex chromosome.

<u>d. How many sex chromosomes are present in a human ovum?</u>

As I mentioned in the previous question, a human ovum has 1 sex chromosome. That way, when it combines with a sperm cell, which also has 1 sex chromosome, they form a zygote with <u>a pair</u> of sex chromosomes (one that comes from the mother and one from the father).

Fever results from the stimulations of the hypothalamic thermoregulatory center by: A prostaglandins B granuloma C opsonin D All
FrozenT [24]

Answer:

A prostaglandins

Explanation:

Fever is the abnormal body temperature that is caused by pyrogens.Pyrogens  are the chemicals produced by pathogen. Fever is protective mechanism of body to fight against pathogens. It is actually the immune response that spread to whole body with elevated temperataure. The elevated temperature helps to deal with pathogen more efficiently.

The interleukins released be immune cells in response pyrogen ultimately lead to release of prostaglandin E2. Prostaglandin E2 reset the hypothalamus thermoregulation. The hypothalamus feels the body temperature is cool although how high is the body temperature.

What do you think is likely to happen if the sphincter at the base of the esophagus does not function properly?
dangina [55]

Answer:

When the lower esophageal sphincter is atrophied, a disease called achalasia occurs, in which there is no relaxation of the esophagus when the food is swallowed,  it is difficult for the food to go down to the stomach. Some symptoms are that the food, once swallowed, can not pass and gets stuck.

Regurgitation, chest pain and weight reduction may also occur.

Label the components of the neuromuscular junction with the most appropriate and specific term provided.
natka813 [3]

The neuromuscular synapse is a chemical synapse between a motoneuron and a muscle cell (muscle fiber). The neuromuscular synapses consist of:

• the pre-synaptic cell-motoneuron that sends signal by releasing the the neurotransmitter from the synaptic vesicles  

• synaptic cleft, place where neurotransmitter is released, between motoneuron and muscle fuber

• post-synaptic cell also called endplate -the muscle cell that receives the signal via receptors.
