What is the direct result of this biological process?
a) duplication of genetic material
b) formation of mutations within cells
c) fertilization of an egg with a sperm
d) generating new combinations of alleles
Answers
Answer:
C
Explanation:
The direct result of this biological process is generating new combinations of alleles. The correct option is d.
What are chromosomes?Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.
"Allele" is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. When chromosomes cross over happens, the alleles changes and a new combination produces.
Therefore, the correct option is d. generating new combinations of alleles.

A male shark has 40 chromosomes in each of its sex cells. How many would be present in its body cells?
Answers
Answer:
80 sex cells would be present in its body cell
If a male shark has 40 chromosomes in each of its sex cells, then the number of chromosomes that would be present in its body cells is 80.
What are Chromosomes?Chromosomes may be defined as thin, thread-like structures that appear during the process of cell division. Chromosomes are typically found in the nucleus in the form of chromatin thread and these threads are made up of DNA, RNA, histones, etc. Chromosomes were first discovered by E. Strasburger in 1875.
It is a significant feature of the germ cells or sex cells that they usually contain half the chromosomes in their cells as compared to the normal body cells. These types of cells undergo meiosis.
The half number of chromosomes from each parental cell is successfully fused in order to produce an organism that has normal chromosomes.
Therefore, there are 80 chromosomes that are present in the body cells of a male shark if it has 40 chromosomes in each of its sex cells.

komori t. the effects of phosphatidylserine and omega-3 fatty acid-containing supplement on late life depression
Answers
Consuming PS (phospholipid) and omega-3 fatty acid supplements, such as Komori T., lowers stress levels, promotes relaxation, and has a beneficial impact on mood.
What are omega-3 fatty acids and phosphatidylserine? Why should people with late-life depression take their supplements?A phospholipid is PS. The phospholipids in cell membranes play a crucial role. Since PS is involved in cell-to-cell communication and the delivery of biochemical instructions into the cell, which ultimately affects the function of the cell, it is particularly abundant in the brain and nerve cells.
You can obtain omega-3 fatty acids via food or supplements, and they aid in the development and maintenance of a healthy body. They provide energy and support the proper functioning of your immune system, heart, lungs, blood vessels, and other organs.
Particular fish tend to include two important ones, EPA and DHA. Alpha-linolenic acid (ALA), a different omega-3 fatty acid, is derived from plant sources including nuts and seeds.
PS lessens older people's depressive symptoms. In a study, depressed senior participants who took an omega-3 supplement reported a significant improvement in their depressive symptoms. Those who saw the highest benefits also experienced a return to normalization of their increased cortisol levels and circadian rhythms (sleep-wake cycle).

Starch is a complex carbohydrate found in plants which contains approximately 200 glucose molecules. Predict the function of starch and explain your prediction
Answers
Answer:
Explanation: Complex carbs are polysaccharides (which is a carb whose molecules consist of a high number of sugars). Starch is a great carb for plants because the type of carb starch is will allow the plant to store energy to give it strength and to support it's life. Thus starch will create chemical energy for the plant. So for example if there was all of the sudden darkness around the plant due to clouds, storms or overcast- the plant wouldn't be getting the sun it needs to grow. So it could break down the starch and use it.

Is the ant nebula or blinking nebula bigger?
Answers
An identifiable luminous component of the interstellar medium known as a nebula can be made up of cosmic dust in addition to neutral, ionised, or molecular hydrogen.
Like the "Pillars of Creation" in the Eagle Nebula, nebulae are frequently areas where stars are being formed. These areas are where gas, dust, and other material formations "clump" together to generate denser regions that eventually attract other matter and reach a density where stars can form. Planets and other objects of the solar system are thought to be formed from the material that is left over.
Young bipolar planetary nebula Mz 3 in the constellation Norma has four different high-velocity outflows, dubbed lobes, columns, rays, and chakram, in addition to a bright core.
A planetary nebula called NGC 6826 can be seen in the Cygnus constellation. Despite the fact that other other nebulae also display this "blinking," it is often known to as the "blinking planetary."

In this group of people with post-stroke spasticity in three 12- to 42-week clinical trials who had >/=1 therapy with a particular BoNTA formulation at doses spanning from 100 to 400 U, the formation of NAbs was uncommon (1/191).
What is Spasticity?Spasticity is a characteristic of altered skeletal muscle function along with paralyzing, enhanced tendons reflex activity, and increased tone. Its name comes from the Greek word spasms, which means "drawing, pulling." It is also known as an unusual "tightness," "stiffness," or "pull" of muscles in everyday speech.
Clinically speaking, spasticity is the result of excessive velocity-dependent muscular contraction brought on by the motor neurons' loss of inhibition. In the end, this results in hyperreflexia, which is an accentuated deep tendon reflex. The medication baclofen, which works as an agonists at inhibitory GABA receptors, is frequently used to treat spasticity.
The most prevalent type of cerebral palsy, that is a collection of persistent movement issues that do not become worse with time, is spastic cerebral palsy. Baclofen's effectiveness as an anti-spasticity medication is influenced by the inhibiting effects of GABA.
