5 steps in the Nitrogen Cycle

Fixation - Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use.

Nitrification - Nitrification is the process which converts the ammonia into nitrite ions which the plants can take in as nutrients.

Assimilation - Assimilation is the process by which plants and animals incorporate the NO3- and ammonia formed through nitrogen fixation and nitrification.

Ammonification - After all of the living organisms have used the nitrogen, decomposer bacteria convert the nitrogen-rich waste compounds into simpler ones.

Denitrification - Denitrification is the final step in which other bacteria convert the simple nitrogen compounds back into nitrogen gas (N2 ), which is then released back into the atmosphere to begin the cycle again.

Differentiate between active natural immunity and passive natural immunity?

Bingel [31]

Explanation:

A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one's own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body.

A cytoskeleton is:_______.

Softa [21]

Answer: e

Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.

1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.

2. The cytoskeleton provides support and shape to cell.

3. It help in transporting substances through cell.

4. It help in phagocytosis.

5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.

6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.

A cleft chin is a dominant trait. One parent is heterozygous for cleft chin, and the other parent does not have a cleft chin. Wh

Sunny_sXe [5.5K]

Answer:

2 out of 4

Explanation:

Let the allele for cleft chin be represented by A, while the alternate recessive version would be a.

A parent that is heterozygous for cleft chin would have the genotype Aa.

A parent without cleft chin would have the genotype aa.

Aa x aa

Aa Aa aa aa

Aa - cleft chinned = 2/4

aa - normal chin = 2/4

Thus, two out of every four (2/4) of their offspring would have cleft chin.

Wewaii [24]

The correct answer is B. Genetics

Explanation:

In health, a risk factor is a variable that can make a patient more likely to develop a disease or condition. Additionally, some of these factors can be controlled or changed by the patient, while others cannot be modified. Factors that can be controlled include stress, diet, weight, alcohol intake, and habits. This does not apply to factors such as age or genetics, for example, in the case of genetics, this is determined by the genes of each parent when a human being is formed, and therefore there is not any way to change this; although factors such as diet, stress, or smoking affect the expression of mutations in genes. Thus, the risk factor Jack has no control over is genetics.
