Answer:

A. Plants

Explanation:

Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.

The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.

Answer:

B

Explanation:

So lets go over facts of mieosis and mitosis:

Meiosis is sexual reproduction

Mitosis is asexual reproduction

Meiosis in animals is how they reproduce

Mitosis in animals is how they regenrate their cells

Mitosis copies the orgninal cell.

Meiosis mixes a male and female egg and sperm to form a zygote

Ok, knowing this. We can find our answer.

Since we know meiosis is sexual, and mitosis asexual, we can get rid of C.

We also know that meiosis is in animals, and so is mitosis, so we can get rid of A.

Finally we can get rid of D, since we know due to the male and female genetics(and through the swapping of chromesomes during prophase)that genetic variation occurs in meiosis, but since mitosis copies a single cell, it is not genetically varient.

<u>So the answer must be C, which states that Mitosis has genetically identical cells, while mieosis does not. </u>

Hope this helps! ;)

densk [106]

Answer:

STRESS TEST

SYSTOLE

DIASTOLE

Explanation:

A standard exercise stress test employs an EKG (electrocardiogram) to watch closely any variation in the heart's electrical activity, the heart valves, the activities of the heart muscle, if the heart does not have shortage of blood flow during exercise and to study how heart functions when undergoing physical activity.

Diastole and systole are two levels of the cardiac cycle. They are seen during heart beats function as it pumps blood using a collection of blood vessels that transports blood to each and every singular part of the body. Systole is produced during contraction of the heart to pump blood out, and diastole is produced during relaxation of the heart when it contracts.

Let's consider, 120/80 mm Hg. The up figure stands for the level of pressure in the arteries when the heart muscle contracts --- systolic pressure. The below figure stands for blood pressure as seen when the heart muscle is between beats--- diastolic pressure.
