Answer:

Joint.

Explanation:

A joint can be defined as the location where two or more bones make contact.

Also, a ligament refers to a short elastic band-like tough fibrous tissue that holds the bones of a joint together so as to keep them in place. This joints are able to move (lengthen and shorten) as a result of the presence of muscles.

Basically, this junction known as joints are typically found in vertebrates and it allows for movement and structural support.

Hence, the ability of the human body to make movements such as sitting down, kneeling, standing up, bending, walking, running etc., is solely dependent on the joints. Thus, without joints all vertebrates would be completely rigid and static.

When cells communicate by the signaling process, one cell produces a _________________BLANK that must be received by the _______

velikii [3]

Answer:

1. Signaling molecule

2. Signaling receptors

Explanation:

Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.

For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.

Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.

Choose the best explanation of the difference between evolution and natural selection. Question 7 options: A) Evolution is the i

Bess [88]

The correct option here would be A. Evolution has to do with species changing over time while natural selection is a process that leads to evolution.

<h3>Evolution and natural selection</h3>

Evolution refers to the gradual changes to the morphological and or physiological characteristics of living organisms over time as a result of constantly trying to adjust to their environments.

Natural selection, on the other hand, refers to one of the processes through which evolution takes place. It refers to forces that select for or against traits in organisms.
