Answer:

Most living things are composed of different kinds of cells specialized to perform different functions.

Explanation:

This is because all of the cells in our bodies start from a single fertilized egg.  As cells divide and grow different genes are expressed, resulting in different cell types. Cells differentiate because specific enzymes turn genes on and off in various cell types. Most living things are composed of different kinds of cells specialized to perform different functions.

Marina86 [1]

For most athletes, the period in their yearly training cycle during which it is recommended to begin calorie restriction so as to lose significant amounts of stored body fat is the off-season or early in the preseason. Restriction of energy intake late in the preseason when there is rigorous training or during season when there is competition may impede training, recovery, or performance.

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.

Advantages and disadvantages of both unicellular and multicellular organisms
Brut [27]

Unicellular Organisums:

Unicellular organisms don't live as long and multicellular organisms. Unicellular organisms are smaller and they are faster at reproduction. Disadvantages- Unicellular organisms only have one cell that is used to function their entire being. Short life span, can't grow lager then multicellular organisms.

Multicellular organisums:

Intelligence and Evolution.

Bigger Is Better.

Less Stress Equals A Longer Lifespan.

Cells Can Take Care Of Each Other.

More Energy Is Needed For Normal Functioning.

Infection Becomes A Possibility When Multicellular.

Takes Longer To Reach Maturity And To Breed
