A newly developed drug causes users to lose some muscle control and slur their words, The drug also results in a slowing of central nervous system activity. Depressants slow the central nervous system.

Signals are sent from the brain to the rest of the body, including the internal organs, via the nervous system. Thus, the nervous system's activity regulates a variety of functions, including the capacity to move, breathe, see, and think.

The nerve cell, or neuron, is the building block of the neurological system. There are around 100 billion neurons in the human brain. A neuron has a cell body, which contains the cell nucleus, as well as distinct extensions known as axons and dendrites.

Different neuronal types control or carry out various functions. For instance, motor neurons help the brain send signals to the muscles that cause movement.

Therefore, A newly developed drug causes users to lose some muscle control and slur their words, The drug also results in a slowing of central nervous system activity. Depressants slow the central nervous system.

Answer:

The answer is D, the host is only negatively affected in a parasitic relationship.

Answer:

D

Explanation:

Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.

Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.

Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Answer:

C. The organism undergoes binary fission and creates genetically identical offspring

Explanation:

This because binary fission is the means of reproduction in prokaryotic organisms like bacteria. This refer to the process where a single cell divided into two or more and each looking more exactly like the parent cell..

the process of binary fission, a particular parent cell replicate its genetic material or DNA and then divides into two parts by a process called cytokinesis and each new organism produced then receive one copy of DNA. This occur in bacteria

Answer:

Both earthquake and volcanoes are concentrated in specific regions.

Explanation:

The distribution of earthquake on earth is concentrated in specific zones where the plate tectonic meets or fuse with each other. Volcanoes are also concentrated in specific regions on the earth. Most volcanoes are concentrated on the edges of continents, on island chains, or long mountain ranges beneath the sea. There is a great relationship between earthquake and volcanoes because volcanic eruptions is the cause of earthquake in a region.

Answer:

a mutation in the germinal line changed the phenotype to bright flowers which were capable of attracting more pollinators compared to yellow flowers. Subsequently, this mutation was selected by natural selection, thereby increasing its frequency in the population

Explanation:

A mutation is any change in the nucleotide DNA sequence of the genome of a particular organism. Mutations can be divided into 1-germinal mutations (i.e., mutations that occurred in the gamete cells) which can be passed on to offspring, and 2-somatic mutations (i.e., mutations that occurred in the somatic cells), which cannot be inherited. Moreover, mutations can be neutral, deleterious or beneficial depending on the environment in which the organism lives. When a germinal mutation is beneficial, the organism carrying the mutation will have more chances to survive and reproduce (i.e., a higher adaptive fitness), thereby the organism will have more chance to pass this mutation to the next generation and the mutation will increase its frequency in the population.

Answer:

When a person jumps out of a moving vehicle, he falls forward due to inertia of motion. One example of Newton's first law in real life is, when you are walking with a glass filled with water, you will notice that the water spills at certain locations when you walk at faster pace. The water inside the glass will remain at rest until you move.

Explanation:

Answer:Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

An object at rest stays at rest.

Explanation:

The VDJ recombination is defined as the process where the T cells as well as the B cells are randomly assembled from the different gene segments. These are mainly known as the variables (V), the diversity (D) and the gene (G). This is done in order to generate the unique receptors which is also called as the antigen receptors so that they can collectively recognize the different types of the molecules. It mainly occurs in the constant region of the light chain.
