advantages:Physical barriers play an important role in preventing microbes from reaching tissues that are susceptible to infection. At the cellular level, barriers consist of cells that are tightly joined to prevent invaders from crossing through to deeper tissue.

Physical barriers play an important role in preventing microbes from reaching tissues that are susceptible to infection. At the cellular level, barriers consist of cells that are tightly joined to prevent invaders from crossing through to deeper tissue.

Immune system is a large network of organs, white blood cells, proteins (antibodies) and chemicals. This system works together to protect you from foreign invaders (bacteria, viruses, parasites, and fungi) that cause infection, illness and disease.

Disadvantages of physical barriers in the immune system is causing immuno deficiency disease.

here's your answer.. Option (C): the sun

Answer:

The correct answer is - Ploidy is the number of sets of chromosomes in a biological cell.

Explanation:

Ploidy is the number of sets of the chromosome in a living cell. Ploidy is known for different condition such as haploid, diploid, and aneuploid, and many more depends how many homologues chromosome numbers are present in the cell.

Diploid cells are common in many organisms where one chromosome come from the mother gamete and the other from the father gamete and makes the homologues chromosomes. In diploid homologues, chromosome are 2n where n is the number of homologues of each chromosome.

In haploid there is only one set of each chromosome and mainly takes place by meiosis. In aneuploidy is the condition where the number of homologues chromosomes are not as the normal genome of the organism for example in humans instead of 46 chromosomes there 45 or 47 chromosome found.

Answer:

meiosis

Explanation:

meiosis occurs first in the sex gametes while mitosis occurs later in growing cell

Answer:

The correct answer is - decreased population size at all levels.

Explanation:

A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.

It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

answer : Permeable Rock layers allow the flow of fluid like substances through them, While Impermeable rock layers do not allow the flow of fluid like substance through them.

Explanation:

Permeable rocks are rocks containing pores through Fluid like substances can penetrate through in the rocks. examples of Permeable rocks are ; Sandstones and Chalk

While an Impermeable rock is a rock that does not allow the flow of fluid like substance through it due to the absence of pores in its rock layers . examples of such rock are ; Clay and marble  

Although some permeable rocks might exhibit low level of permeability as well but generally Rock sample with pores are classified as permeable rock layers.

moving the magnet faster thats the answer i can give not sure bit by incerasing coils electrycity is more produced

Moving the magnet faster  would not produce more electricity when a magnet is moved.

A substance or thing that creates a magnetic field is called a magnet. The most noteworthy characteristic of a magnet—a force that pulls on other ferromagnetic elements, such as iron, steel, nickel, cobalt, etc.—as well as the ability to attract or repel other magnets—is caused by this invisible magnetic field.

An object made of a substance that has been magnetized and produces its own persistent magnetic field is referred to as a permanent magnet. A common example is a refrigerator magnet used to keep notes on the door of the refrigerator.

Ferromagnetic materials are those that can be magnetized and are also those that are powerfully drawn to a magnet (or ferrimagnetic). These comprise some naturally occurring materials as well as the metals iron, nickel, and cobalt as well as their alloys.

Therefore, Moving the magnet faster  would not produce more electricity when a magnet is moved.

Answer:

B. Being able to plan in advance for a genetic disorder in a child.

Being able to plan in advance for a genetic disorder in a child is an advantage for a parent who sees a genetic counselor. So, the correct option is (B).

A genetic disorder is a type of disease caused in whole or in part by a change in a DNA sequence away from the normal sequence.

It can be caused by several reasons like

1. Monogenic Disorder

It is caused by a mutation in one gene

2. Multifactorial Inheritance Disorder

It is caused by mutations in multiple genes

3. Combination of gene mutations and environmental factors.

4. Damage to chromosomes by the changes in the number or structure of entire chromosomes, the structures that carry genes.

Genetic counseling helps parents for better understand test results and treatment options, helps deal with emotional concerns, and provides referrals to other healthcare providers and advocacy and support groups.

Thus, being able to plan in advance for a genetic disorder in a child is an advantage for a parent who sees a genetic counselor. So, the correct option is (B).

Answer:

Fishes use a different vision mechanism than mammals and other land animals. They have rods and cone photoreceptors to see the colorful visions and adjust their focal point by moving the lens closer to or away from their retina.

In the water bodies, a difference in the amount of light moves with the depth because water absorbs the light and this change occurs due to the optical nature of water.

The light bounces once it back in the retina, leads to the gain of the small packets of energy of light a second chance to be trapped by photoreceptors. However, vision remains blurry. The changes and distortion of the light-absorbing molecules present in the eyes of fishes make it tough to perceive a clear vision.

The soil will move farther when you pour water gradually.

The presence of rheumatoid factor autoantibodies states that it is an autoimmune process. There are other autoantibodies also associated with this type of arthritis that are rheumatoid factors (RF), anti‐keratin antibodies (AKA), anti‐filaggrin antibodies (AFA), and anti‐perinuclear factor (APF).

Explanation:

I’m pretty sure it’s phenotypes

Answer:

a).Don't know if you meant to write 3x10^10km and 2x10^10km

I'll solve with this... If they aren't the values... You can then input the real values.

Distance = Total length traveled.

D= 3x10^10 + 2x10^10

D= 5x10^10Km

b) Displacement:

Since it went vertically... Then went horizontally in the second phase... It is forming a right angled Triangle and the Displacement would be the Hypotenuse of this triangle.

Disp.= √ (3x10^10)²+(2x10^10)²

Disp.=3.61x10^10km.

Explanation:

Answer:

4 percent (4%)

Explanation:

A single crossover occurs between two (non-sister) chromatids belonging to homologous chromosomes. In this case, 16 percent of the meioses have a single crossover, thereby it will produce 8 percent of the chromosomes with the original (parental) combination in the progeny and the remaining 8 percent should be recombinants. From this result, it is reasonable to conclude that half of these recombinants should be 'Br' (and the other remaining 4 percent should be recombinants 'bR'), and therefore the answer is 4 percent (4%).
