why is repetition important in science?

The Cell-mediated response results in the production of macrophages to use phagocytosis on pathogens. The correct option is C.

Cell mediated immune response occurs when an invading antigen causes the release of cytokines (Interleukins), differentiation of T cells and production of macrophages.

Macrophages are produced through the differenciation of monocytes. They are further activated during an infection through the macrophage-activating cytokine (Interleukins).

Phagocytosis is the process used by immune cells such as macrophages  which involves ingesting and eliminating pathogenic microorganisms.

Cell-mediated response dosent result to differenciation of helper T cells into cytotoxic T cells rather it leads to the activation of cytotoxic T cells. Therefore B is wrong.

Cell-mediated response dosen't lead to the production of antibodies therefore option D is wrong.

Answer:

Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. ... Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.

Explanation:

because speed is time rate at which an object is moving along a bath, while velocity is the rate and direction of object's movement .

Answer:

In plants, carbon dioxide (CO2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized. ... This type of reaction is called a reduction reaction, because it involves the gain of electrons.

Answer:

First thing is that word “autonomous” given in the question is actually “ autosomal”.

Now let's start solution:

Frequency of dominant allele “A” is denoted by p.

Here p = 0.6

Frequency of recessive allele “a” is denoted by q.

According to Hardy - Weinberg equilibrium

p + q = 1

Hence q = 1 - p = 1 - 0.6 = 0.4

Now in question what is asked is about frequency of recessive phenotype (aa).

According to Hardy - Wienberg equilibrium frequency of recessive phenotype is q2 (q square).

Frequency of recessive phenotype is = q2 = 0.4 x 0.4 = 0.16

Now Number of recessive phenotype in a population of 10000 is

= frequency of recessive phenotype x total population

= q2 x 10000

= 0.16 x 10000

= 1600

Answer:

C. I and III

Explanation:

A mutation needs to occur in a gamete cell in order to be passed down to the next generation.

If it occurs in a somatic (body) cell, the mutation will only be present in that organism.

On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.

So, since sperm and egg cells are gametes, mutations in those cells would get passed on.

The correct answer is C. I and III

Answer:

if a special effects artist mixes two different liquids in a bowl and they both are too white !

after heats those liquids

its forms curd like substance

its either will be white, its can increase its colour as darkish white or lightly yellowishblack

when she heats the bowl, a new compound forms and it will be white before heating and after heating it may be white or other dark color.

A compound composed up of two or more elements which are chemically combined with a fixed proportion by their mass.

For example, Water, Sodium Chloride,  Ammonium Chloride etc.

They have fixed melting and  boiling points.

Formation of compound is a change in chemical reaction and the components of compound are mixed in a fixed proportion.

Two major types of compounds are covalent and ionic compounds.

Covalent compounds refers to formation of covalent bond among two nonmetals, like water or methane. These molecules are neutral and weak.

When metal react with non metal it form Ionic compounds, are held together by opposite charges, so the bond is stronger than covalent compound.
