Answer:

Two factors determine whether a molecule will cross a membrane:

1. the permeability of the molecule in a lipid bilayer and

2. the availability of an energy source.

The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of lipid and is highly soluble in the nonpolar environment of the lipid bilayer.

boyakko [2]

Answer:

homologous

Explanation:

<em>Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.</em>

Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.

The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.

The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.

The moon.

Explanation:

High tides and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon.
