Answer:

Functional specialisation explains how the two cerebral hemispheres are specialized in different types of mental activity.

Explanation:

The nervous systems of all animals have in common a number of basic functions, the most notable of which are control of movement and analysis of sensation. What sets the human brain apart is the variety of more specialized activities it is capable of learning and the integration and control of the different functions. In 90% of the population the left cerebral hemisphere specializes or controls the ability to speak and write, and the ability to understand spoken and written language. In the remaining 10%, the right hemisphere or both hemispheres dominate spoken or written language. The right cerebral hemisphere perceives tactile stimuli and spatial vision relationships better than the left hemisphere. Another area, the posterior-parietal lobe is related to the tactile abilities, it is particularly involved in the abilities to name and point out the parts of the body, one's own and of others, as well as in the abilities to name, distinguish, recognize or draw the fingers of the hand. The parietal lobe is particularly involved in perceptual accuracy in locating stimuli, in estimating line orientation (parietal-frontal lobe) and in the ability to estimate the number of stimuli presented in the central visual field.

Match each type of cell junction with its description.

Ne4ueva [31]

Answer:

Tight junctions - prevent liquid from seeping between cells

Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves

Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells

Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials

Explanation:

1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.

2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.

3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.

4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.

What are the FIVE ways an object's motion can change?

Lisa [10]

Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.

Why does population size of a species rise and fall around the carrying capacity, rather than immediately stop growing and flatt

salantis [7]

Answer:

soarce google

Explanation:

Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

Which structural component is found in DNA but not in RNA?

Over [174]

I believe the correct answer is B. Deoxyribose

<h2>Explanation:</h2>

The nucleotide of a DNA is slightly different to that of RNA due to an addition of a hydroxyl (OH) on the sugar molecule on the RNA nucleotide located on position 2 of the nucleotide.

<h2>Further Explanation:</h2>

The DNA and RNA molecules are almost similar.

<h3>1. Nitrogenous bases</h3>

They both have a nitrogenous base on position one. The nitrogenous base can be one of the 5 bases Adenine, Cytosine, Guanine or Thymine which can be coded by their alternate Uracil in the right places. They are considered to be the building blocks of the DNA and RNA molecules.

<h3>2. Phosphate group</h3>

Located on position 5 of the nucleotide of both in RNA and DNA is the phosphate group. It has important functions including forming part of an ATP molecule to provide the body with the required energy. They also activate proteins through a process called phosphorilation for example in the cAMP cycle they activate protein kinases.

<h3>3. Ribose</h3>

On the second carbon position there is a ribose sugar. It has only one oxygen molecule linked to each one of the 5 carbon atoms. On the second carbon position, the oxygen molecule is bound to a hydrogen atom forming a hydroxyl (OH). It is only in the RNA that the ribose sugar exists giving it its name; Riboneucleic acid.

<h3>4. Deoxyribose</h3>

The prefix deoxy- means that lack of oxygen. That is where the name deoxyribonucleic acid (DNA) comes from. On the second carbon position of the nucleotide is where there is lack of the oxygen molecule that usually binds to the carbon and hydrogen molecules leaving a hydrogen only bound to the 2nd carbon position. This sugar is only found in the DNA molecule. This small lack of an oxygen bound to the hydrogen allows specific enzymes to be able to identify the difference between a DNA molecule and an RNA molecule.
