The role is speeding up chemical reactions
Explanation:
A valid experiment must have results that can be repeated.
The probability of life evolving into a complex form is one of the factors in the Drake equation. Drake himself estimated that probability as 1.0, for what that's worth.
<span>He had that confidence precisely because descent-with-variation seems pretty certain to be a universe process because it's so straightforward. If you have something that reproduces imperfectly, eventually more complex versions will be the result. Even the "natural selection" part is optional if you were just imagining searching through the vast space of genetic possibilities, but finite resources make selection inevitable.</span>
Answer:
Absorption
Explanation:
Epithelial tissue aid absorbtion, secretion, and excretion of substances. In the intestines, it aid absorbtion of nutrients during digestion.
The columnar epithelium possess pillar-like and column-like cells located in the lining of the stomach and intestine. It aid absorption and secretion.
The types of animal tissues are the Connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connectuve Tissues arises from the mesoderm. All connective tissue is made up of three major components: fibers (elastic and collagenous fibers), ground substance and cells.
Basic functions of connective tissues includes binding and supporting, protecting, insulating, storing reserve fuel, and distribution of substances within the body.
