Answer:

Option D

Explanation:

Small, non polar and uncharged particles moves across the membrane by the process of simple diffusion in order move in and out of the cell

These substances includes,carbon dioxide, oxygen, ethanol, water, urea et cetera.

The large polar and charged molecules such as carbohydrates, fats, protein and ions cannot freely diffuse through the membrane and are transported by the help of carrier protein as they are too large.

Hence, the correct answer is option D

Answer:

Earth's primordial soup

Explanation:

Alexander Oparin was a Soviet biochemist who proposed theories for the origin of life through a book he called "The Origin of Life". He claimed that life on earth came about as a result of a gradual chemical evolution which is a mixture of carbon-based molecules that he called Earth's primordial soup (or sometimes called "organic soup").

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{\text{Equal and Opposite Force on the Person}}$

<h2>_____________________________________</h2><h2> $\Huge\textbf{3rd Law of Motion}$ </h2>

$\large\texttt{"To Every action there is always an equal and opposite reaction"}$

Consider two bodies A & B which collide with each other. If $F_{AB}$ be the force exerted by the body A on Body B. Then Body B will also exert force $F_{BA}$ on Body A which is equal in magnitude but opposite in direction.

$F_{AB} = - F_{BA}$

The force exerted by Body A on Body B is called Action, and the force exerted by the Body B on Body A is called Reaction.

What question was investigated based on the data graphed here?

Semmy [17]

Answer:

<u><em>The correct option is D) Does the amount of radiation from the sun affect air temperature?</em></u>

Explanation:

The graph represents the effect of Sunlight or global radiation on the temperature of the air present in the atmosphere.

As we know, as the amount of radiation increases, the temperature of the Earth also increases. This phenomenon is perfectly illustrated in the graph mentioned in the question. Hence, D is the correct option.

Other options like option A are not correct because the graph does not illustrates the parts of the Earth which receive the most global radiation over a year.

Some types of muscular dystrophy are X-linked recessive disorders. A mother who is a carrier for muscular dystrophy has children

marissa [1.9K]

D gene is an X-chromosome-linked gene. a) 100% will have the disease, XdY // 0% will be carriers. b) 0% will have the disease // 100% will be carriers, XDXd.

<h3>What are the séx-linked genes?</h3>

These are genes that can be found only in the X-chromosome. The inheritance pattern expressed by these genes varies from the one expressed by genes located in autosomal chromosomes.

In the exposed exampe,

- muscular dystrophy are X-linked recessive disorders

- woman ⇒ carrier for muscular dystrophy ⇒ heter0zyg0us ⇒ XDXd

- man ⇒ doesn’t have muscular dystrophy ⇒ X-chromosome with the dominant allele ⇒ XDY

- XD ⇒ chromosome rarrying the dominant allele

- Xd ⇒ chromosomes carrying the recessive allele

Cross: Man x Woman

Parentals) XDY x XDXd

Gametes) XD Y XD Xd

Punnett square) XD Xd

XD XDXd XDXd

Y XdY XdY

F1) 1/2 = 50% of the progeny will express the normal phenotype, XD-

1/2 = 50% of the progeny will have muscular dystrophy, Xd-

100% of the girls will be normal and carriers, XDXd

100% of the boys have muscular dystrophy, XdY

a. What percentage of their sons will have the disease, and what percentage of their sons will be carriers?

Considering only boys,

100% of them will have the disease, XdY
0% will be carriers.

b. What percentage of their daughters will have the disease, and what percentage of their daughters will be carriers?

Considering only girls,

0% of them will have the disease,
100% will be carriers, XDXd
