S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?

Answers

Answer 1

S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.

S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.

In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.

It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.

gene regulation can occur only during transcription and translation.

Answers

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.

while a neuron membrane is depolarizing its __________.

Answers

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.

Answers

ANSWER:

The potential energy of the book is 245 J.

mass m = 10 kgheight above a reference point h = 2.5 m

Use the formula for potential energy. ( g = 9.8 m/s² )

[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]

the type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only.

Answers

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.

Answers

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.

Moreover, photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Hence, the primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process. It's not particularly efficient by human engineering standards, but it does the job.
