Explanation:

6.Saturated fatty acids do not contain double bonds(only single bonds) .Unsaturated fatty acids contain one or more double bonds.

7.There are 3 classes of lipid which is triglycerides, steroids and phospholipids.

8.Triglycerides

-Provide insulation that keeps you warm while protecting your internal organs with a layer of padding.

-When you don't burn all the calories you consume, they converted to triglycerides and stored for future use.

Steroids

-It plays a role in cell repair

-It also plays a role in formation of new cells

Phospholipids

-Protecting cells

-Insulating cells

What is a scientific theory?

Vadim26 [7]

A scientific theory is a specific type of theory used in the scientific method. The term "theory" can mean something different, depending on whom you ask.

"The way that scientists use the word 'theory' is a little different than how it is commonly used in the lay public," said Jaime Tanner, a professor of biology at Marlboro College. "Most people use the word 'theory' to mean an idea or hunch that someone has, but in science the word 'theory' refers to the way that we interpret facts."

Effectus [21]

Similarities and differences are explained below

Explanation:

Differences:

somatic nervous system:

It is part of the peripheral nervous system associated with the voluntary control of body movements through the skeletal muscles and mediation of involuntary reflex arcs.
It has sensory and motor pathways.
It controls muscles and movement.
System responses are based on skeletal muscle contraction.

Autonomic nervous system:

The autonomic nervous system is subdivided into the sympathetic nervous system and parasympathetic nervous system
It possesses only motor pathways.
It controls glands and internal organs.
This system works automatically, without a person's conscious effort.

Similarities between the somatic nervous system and the autonomic nervous system:

Both have motor pathways

Both the system use nerve impulse

Both the system Weaken Myocytes

Both the system use glucose as an energy source for the muscles that they control

Both the system are controlled by the CNS

Both possess neurons

In a population of 10,000 individuals of Monstera deliciosa, four individuals have a variegated phenotype that is caused by the

Mariulka [41]

Under the assumption of this population being in Hardy-Weinberg equilibrium, the probability for the fixation of the var recessive allele equals 0.02 = 2%

--------------------------------

Available data:

N = 10,000 individuals ⇒ Large population

4 individuals have a variegated phenotype

variegated phenotype is caused by the recessive var allele

No selection, no additional mutation ⇒ we can assume Hardy-Weinberg equilibrium

We need to know the probability for the fixation of the var allele.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of variegated individuals in the population.

There are 10,000 individuals, and only 4 have variegated.

So, the phenotypic frequency, F(Var) is 4/10,000 = 0.0004 = 0.4%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(vv) = 0.4%

Finally, we can get the allelic frequency by taking the square root of this value.

F(vv) = q² = 0.0004

f(v) = q = √0.0004 = 0.02 = 2%

According to these calcs, the probability for the fixation of the var allele is 2%, and the probability that all individuals express the variegated phenotype is 0.4%.
