The answer should be NEURONES (nerve cells).
Neurons transmit electrical signals called NERVE IMPULSES from the cell body through the axon to the end plate. The junction between the end plate and the adjacent cell is called SYNAPSE. impulses passes through the synapse by diffusion of chemicals.

Which one of the following is NOT a characteristic of the carrying
Tems11 [23]

Answer:

<em> The carrying capacity is determined only by the density-dependent factors.</em>

Explanation:

The maximum number of organisms of a particular species that an environment can hold is known as the carrying capacity of that environment. The carrying capacity depends on density-dependent factors as well as density- independent factors like weather, sunlight etc.

Beyond the carrying capacity, the organisms will begin to fight with each other for limited resources. The environment will become unstable as the resources will be scarce and individuals will be more.

Alexandra [31]

The question is incomplete as it lacks te end part of the question. However, the missing part is as follows:

In the F2 generation, all possible combinations of these traits were expressed in ratios consistent with Mendelian inheritance. Identify the four dominant traits, and enter them in ALPHABETICAL order in the blanks provided. [x],[y],[z],[a].

Answer:

The correct answer is :

x)axial

y)full

z)round

a)violet

Explanation:

True breeding organisms are organisms that carry two same alleles of a particular trait or character either dominant or recessive. In this given case the two breeding plants have four distinct traits, round, terminal, violet, constricted in one parent and wrinkled, axial, white, full in other.

In f1 there would be only dominant alleles for these characters will be expressed, that is already given in the question-

round, axial, violet, and full

The alphabetical arrangement of the dominant alleles are-

x)axial

y)full

z)round

a)violet

DanielleElmas [232]

Amniocentesis or Amniotic Fluid Test or Amnio is the process to examine genetic defects, fluid infection or sex determination by inserting a needle into the Amniotic fluid surrounding the unborn fetus.

<u>Explanation:</u>

<u>Amniocentesis</u>

Amniocentesis is a prenatal diagnosis which is used to determine genetic defects, fluid infection or sex determination by inserting a needle to draw a small sample of fetal cells through the amniotic fluid surrounding the unborn fetus.

The prime aim of Amniocentesis is to detect chromosomal deficiencies and cure the fetus with all possible processes so that the baby may be normal and healthy at the time of delivery.

This process is performed when the woman is 15-20 weeks pregnant. The test has the tendency to spread quick and possesses the probabilities of miscarriage.
