Cells can regulate what they need or don't need to maintain their own health. True False

Biology
1 answer:
Yakvenalex [24]3 years ago

True. This is called cellular homeostasis. This happens when cells are able to produce and excrete materials within their environment to regulate processes like cellular respiration, phagocytosis, and pinocytosis. If cells are not able to do this, mutations and excessive cellular division may occur causing abnormalities in specific organisms.

What does it mean if a population is in Hardy-Weinberg equilibrium? Be specific.
Andrej [43]

Answer:

The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.

It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.

Restriction endonucleases are especially useful if they generate sticky ends. What makes an end sticky?
Mazyrski [523]

The question is incomplete as it does not have the options which are:

A) single-stranded complementary tails

B) blunt ends

C) poly-A sequences

D) 5' cap

E) interference

Answer:

A) single stranded complementary tails

Explanation:

Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.

The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.

The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.

Thus, Option-A is correct.
