Answer:

FALSE

Explanation:

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one elect

A positive feedback loop causes a self amplifying cycle in which a physiological change leads to even greater change in the same
iVinArrow [24]

The given statement is TRUE.

A positive feedback loop causes a self amplifying cycle in which a physiological change leads to even greater change in the same direction.

A negative feedback loop is a process in which the body senses a change, and activates mechanisms to reverse that change.

What is a positive feedback loop?

In nature, a positive feedback loop happens when the outcome of a reaction increases that reaction. A positive feedback loop pushes a system further away from the equilibrium goal if we consider a system in homeostasis. It takes place when something needs to happen quickly and does this by enhancing the effects of a product or event.

<u>Example</u> : Ripening of fruit

In nature, there is a strange phenomenon when a tree or bush may suddenly and silently begin to ripen all of its fruit or veggies. This is the first instance of a beneficial biological feedback loop we've found. If we see an apple tree with many apples, they all appear to ripen over night, going from being unripe to ripe to overripe. The first apple to ripen will mark the start of this. It releases ethylene (C2H4) via its skin when it is ripe. The apples nearby ripen as a result of being exposed to this gas. As soon as they are ripe, they too begin to generate ethylene, which continues to ripen the rest of the tree in a manner akin to a wave.

Based on the information above, which of the following is true about the process in which the genetic code stored in DNA is used
DanielleElmas [232]

Answer:

D.This process requires the interaction of several different cellular structures,

Explanation:

We don't have the information above. However, this process occurs in all cells, and it requires energy. Semi-conservative refers to the fact that, during DNA replication, each new molecule of DNA is made up of one strand of the original DNA molecule and one strand of a new molecule.

The synthesis of proteins from the information in an mRNA molecule does require several structures in the cell, including the nucleus, ribosomes, endoplasmic reticulum and Golgi apparatus.
