Two layers<span>The structure is called a "lipid bi-layer" because it is composed of two layers of fat cells organized in two sheets. The lipid bi-layer is typically about five nano meters thick and surrounds all cells providing the cell membrane structure.</span>

Explanation:

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Katen [24]

Answer:

They had a large brain size of 700 to 1,250 cubic centimeters and large brow ridges with a nuchal torus at the back of the skull.

Explanation:

<em>Homo erectus</em> was one of the species of the homo genus which were considered the first species to have the human-like the feature that is they can stand upright on two legs and were therefore referred to as the upright man.

They showed many evolutionary advances over their ancestors called Homo Australopithecus as they showed encephalization. Encephalization refers to the increase in the size of the brain due to more neuronal complexity and neurogenesis and they possessed about 750 to 1250 cc brain size.

They showed torus at the back of the muscle which can hold the muscle of the neck and also showed the large brow ridges in the front of the skull.

Thus, the selected option is the correct answer.

The taxon species may be defined by reproductive isolation and _____.
ivann1987 [24]
<h3><u>Answer;</u></h3>

Morphology

The taxon species may be defined by <em><u>reproductive isolation and morphology </u></em>

<h3><u>Explanation;</u></h3>
  • <em><u>A taxon is a group of one or more populations of an organism. </u></em>
  • <em><u>Morphology is the form or the appearance of a particular organism, </u></em>while <u><em>reproductive isolation is the separation of organisms by some type of barrier.</em></u>
  • <em><u>Reproductive isolation is a type of mechanisms that prevent two or more organisms or populations from exchanging genes through reproduction. </u></em>This occurs when two organisms or species are separated for too long such that they can no longer reproduce with each other due to different adaptation and changes in the environment.
  • <u><em>Morphology and reproduction isolation may be defining characteristics of taxon of species.</em></u>
