Can someone explain question 4?

Answer:

Sunlight.

Explanation:

Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.

Answer:  the given protein segment contains 20 amino acids

The given segment of the polypeptide chain is made up of four different types of amino acids, and each amino acid is connected to each other by the peptide bond, and the chain elongates from the N terminal to the C terminal.

There are 20 different standard amino acids that take part in polypeptide chain synthesis, and those are categorized into some particular types such as hydrophobic amino acids, hydrophilic amino acids, charged and uncharged amino acids, etc., and different compositions of the amino acids make different types of proteins. The polypeptide chain is generally synthesized from the N terminal to the C terminal, and here in the given diagram, there are four amino acids, and each amino acid has an amino group, a carboxylic group, a hydrogen group, and one side chain bonded to a single central carbon atom.

Hence, the given segment of the polypeptide chain is made up of four different types of amino acids.

Answer:

F. The genes for black hair were activated by specific temperatures

Explanation:

The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that its cold.

Rabbits regulate their body temperature by using their ears. A fever or a dip in body temperature could be indicated by extremely chilly or hot ears. Thus, option F is correct.

In general, rabbits thrive in cooler climates. In the fall, rabbits stop shedding their fur and develop a thick coat of fur that keeps them warm in the winter. Low temperatures of 32 degrees don't really bother them.

Strong back legs offer rabbits the speed they need to run away from predators. Their feet have fur on the bottoms for warmth and strong claws for traction.

Answer:

Air masses have fairly uniform temperature and moisture content in horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the the underlying surface properties where they originate.

Answer:

Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells

Explanation:

The correct answer would be that each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells .

Cell differentiation occurs when a specific segment of the DNA of a cell is expressed during gene regulation and control. The segment of DNA expressed would be dependent on the function the cell is meant to perform. Thus, if cell A is meant to perform an excretory role and cell B is meant to perform a digestive role, even though cells A and B contain the same DNA, different segments of their DNAs would be expressed so that each cell becomes adapted to its role.

Answer: The theory states that the earth's crust is divided into massive slabs known as tectonic plates.

Explanation:

These plates move on the mantle which is a layer made of magma, which consists of semisolid rocks.The heat from earth's core causes convection currents much like in a beaker full of water.But, here the force developed by the magma is so great that it slowly moves the plates like boats on sea over millions of years.
