Which phrase describes transmutation?(1 point) the conversion of protons to neutrons through nuclear changes the conversion of one substance to another through chemical changes the conversion of an atom of one element into a different element through nuclear changes the conversion of energy to matter through chemical changes

Answers

Answer:

B

Explanation:

PLEASE MARK AS BRAINLIEST!!!!!

Transmutation is conversion of an atom of one element into different element through nuclear changes.

Transmutation consists of the conversion of stable nuclei into other nuclei if they are bombarded by fast particles.

Specifically, an atom can be transmuted by making particles or atoms collide with it at high speed, that is, to accelerate a particle is to increase its speed by some mechanism that imparts energy to it.

Thus, the transmutation of an element requires that there be a change within its nucleus, and in particular in the number of protons.

The neutrons or protons must have enough energy to overcome the nuclear forces that prevent their passage or exit from the nucleus of the atom to be transmuted.

Therefore, we can conclude that transmutation is conversion of an atom of one element into different element through nuclear changes.

which combination of cells and growth factors would serve as the control group?​

Answers

Answer:

These stimuli, called growth factors, are naturally occurring proteins specific to certain groups of cells in the body. They include nerve growth factor, epidermal growth factor, and platelet-derived growth factor.

Explanation:

Hope this helps.

Growth factors are defined as the proteins that bind to specific receptors, which activate the cascade of signal transductions. The growth factors lead to proliferation, apoptosis, and development.

Different types of growth factors stimulating the signal transduction are:

1. Nerve growth factor is controlled by the gene NGF. It provides the instructions to make the beta protein, which is important for the survival and development of the nerve cell.

2. Epidermal Growth Factor is a type of factor that stimulates cell development and cell proliferation. It generally stimulates the fibroblasts and epithelial cells.

3. Platelet-derived growth factor regulates cell division and growth. These factors help in healing and repairing the wound and walls of the damaged blood vessels.

Thus, the growth factors when bound to specific cell receptors control the various activities of the cells.
