They are all mechanisms of Evolution and can change allele frequencies in populations
Natural selection, mutation, genetic drift and gene flow are all capable of causing varying changes in allele frequencies in a population. and these changes leads to the violation of Hardy-Weinberg assumptions
Hardy-Weinberg assumption states that; for a population to experience an unchanged allele frequencies, certain conditions must be met by the population such as ; absence of natural, random mating , absence of migration and absence of mutation.
Hence we can conclude that Natural selection , mutation, genetic drift and gene flow are all mechanisms of Evolution and can change allele frequencies in populations

What are S-strain and R-strain bacteria?
Answer:
When Frederick Griffith discovered two strains of Streptococci in 1923, the bacteriologists were intrigued by the differences between them: the S (smooth) strain, which produces colonies that are smooth and shiny on a lab plate; the R (rough) strain, which lacks a polysaccharide coat and produces colonies that are rough and irregular on a lab plate.

the type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only.
Explanation:
A single parent reproduction is called Asexual reproduction
Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes is not altered.
What is asexual reproduction?The whole gene pool of their single parent is inherited by the children that are produced by asexual reproduction from either unicellular or multicellular organisms.
With asexual reproduction, just one parent is necessary, two parents participate in sexual reproduction, which results in children with distinct genetic makeup.
A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization, budding is an example of asexual reproduction.
Therefore, with asexual reproduction, just one parent is necessary.

[tex] \huge \bf༆ Answer ༄[/tex]
The acceleration produced by that boy is Zero .
_____________________________________
Want to know how ? here's the reason : -
As he is running with a constant velocity, so there's no change in velocity and Acceleration is defined as " Rate of change in Velocity " and since there's no change in velocity and direction (because he is moving in a straight road) hence Acceleration is 0.

The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as
The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.
Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.
Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.
Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

Name the 2 different types of endoplasmic reticulum and explain the function of each type endoplasmic reticulum to the cell . (ie - what does each one 'produce', or make for the cell)
Answer:
The surface of the rough endoplasmic reticulum (ER) is covered in ribosomes, while the smooth endoplasmic reticulum is not covered in ribosomes.
Explanation:
Hence their terms, rough and smooth endoplasmic reticulum, the smooth is like a fine tube whereas the rough consists of ribosomes on its surface. Both the smooth and rough endoplasmic reticulum work together, delegate tasks and are the site for production and storage of proteins.
Smooth ER is responsible for storage and lipids production, while the rough ER is responsible for production of proteins and some hormones.

while a neuron membrane is depolarizing its __________.
Given what we know about the depolarization of neurons, we can confirm that while a neuron membrane is depolarizing its sodium gates are fully open.
Throughout the human body, sodium is often used to cause shifts in membrane potentials, as well as a variety of other metabolic processes, due to the electric charge of this ion. One such example is the neuron, which uses a flood of sodium ions to depolarize its membrane.
During depolarization, the membrane potential changes from a negative charge to that of a positive one. This is caused by the rapid flooding of sodium into the cell, which increases the positive charge in the interior of the cell and thus affects the membrane's potential.

[tex] \qquad {\boxed{\sf P.E._{grav} = m \times g \times h}} [/tex]
[tex] \sf P.E._{grav} = (10\:kg) \times (9.8\: \frac{m}{s^2}) \times (2.5\:m) [/tex][tex] \sf P.E._{grav} = (10\:kg) \times (24.5\: \frac{m^2}{s^2}) [/tex][tex] \sf P.E._{grav} = {\boxed{\sf {245\:J}}} [/tex]Therefore, the potential energy of the book is 245 J.

gene regulation can occur only during transcription and translation.
The statement described is false, gene regulation is a process that can occur at any time during the expression of a gene.
Gene regulation includes all those processes that affect the action of the final products of genes, that is, the regulation of the synthesis of macromolecules is called gene regulation or expression.
This regulation can be carried out at any stage of the synthesis or maturation of the macromolecules, and taking into account many variables it will be developed at the most appropriate point.One of the most important regulation points is carried out at the level of transcription, since this is the initial stage of transfer of genetic information, control is achieved at the beginning.Therefore, we can conclude that the pathway that leads from DNA to proteins is made up of multiple stages, and gene regulation can occur at any time during them.
