What prevents lipids from mixing with water?

The NET reproduction per individual per unit time (r) is _____ per mouse per month in a population of 1,000 mice where 500 mice

Phantasy [73]

Answer:

0.1

Explanation:

The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size

Given that:

Population size of mice = 1,000; Birth = 500; Death = 400,

Net reproduction rate (r) = (births-deaths)/population size

r = (500 – 400)/1000

r = 100/1000

r = 0.1

The Net reproduction per individual per unit time (r) is 0.1

Explain further the idea that indicates that all of life is related and can be divided into three major clades, often referred t

padilas [110]

All of life can be divided into three major clades because it is believed that all branches of the tree of life have the same evolutionary origin.

<h3>What is evolution?</h3>

Evolution is descendence with modification, which generally is due to the process of natural selection.

Evolution indicates that all organisms derive from an ancestral organism (it is related to the cell theory).

In conclusion, all of life can be divided into three major clades because it is believed that all branches of the tree of life have the same evolutionary origin.

Biologists use the fluid mosaic model to describe membrane structure.

allochka39001 [22]

<h2>The correct answers are enlisted below:</h2>

Explanation:

Three correct statements are:

Statement: 1.
Statement: 2.
Statement: 3.

The cell membrane is comprised of a phospholipid bilayer that remains interspersed with protein molecules.
Each phospholipid molecule is comprised of:

A glycerol molecule linked with the help of ester bonds to,
one phosphate group,
two fatty acid (saturated or unsaturated) molecules.

Being hydrophilic in nature, the phosphate group faces outside the lipid bilayer forming hydrogen bonds with the water molecules.

Being hydrophobic in nature, the fatty acid molecules faces to the interior of the bilayer avoiding contact with water and forming hydrophobic interactions with each other.
The saturated fatty acid molecules have a straight hydrocarbon chain as they lack any double bonds. However, the unsaturated fatty acid molecules possess multiple double bonds that generate a kink or bent in their structure. The kink causes the molecules to occupy more space in the bilayer and also help these molecules to move laterally about their position, thereby generating fluidity in the membrane.
The lateral movement of the lipid molecules also causes the lateral movement in the interspersed protein molecules.
The interspersed protein molecules has various functions like, they act as channel proteins, carrier proteins, receptor proteins, etc.
