It is known as a transgenic organism. This procedure is otherwise called "genetic engineering." Genes of one species can be altered, or qualities can be transplanted starting with one animal types then onto the next. Genetic engineering is made conceivable by recombinant DNA innovation. Living beings that have modified genomes are known as transgenic.

vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.

2. neurons that detect chemicals such as those found in food. Chemoreceptors.

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.

4. the structure that gives the response to an environmental change. Effector

5. neurons that detect electrical fields. Electroreceptors.

6. secretion of hormones into the blood stream to affect distant processes. Endocrine.

Explanation:

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

A man who smokes heavily has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, ma

Naya [18.7K]

Answer:

The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.

Explanation:

The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.

What identity status has an individual adopted who has neither experienced an identity crisis nor commitment?

PolarNik [594]

Answer:

Identity Diffusion

Explanation:

A person whose identity status is Diffusion has not had an identity crisis and has not yet fully realized their social identity or personal traits. Moreover, this person is not seeking to make a commitment to establish his or her identity. It is almost like identity Foreclosure; however, in that stage, the person adopts some traits and qualities of friends and parents.
