What is 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.

Explain Newton’s First Law and give an example of it
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.

in VDJ recombination occurs in the Group of answer choices variable region of the heavy chain. constant region of the light chain. variable region of the light chain. Both the light and heavy chain.
Answer:
constant region of the light chain.
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.

12. Which has NOT been linked to acid precipitation?
a. Toxic metal poisoning
b. Lower blood pH
c. Respiratory problems
d. Damaged monuments
Answer:
D
Explanation:
Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).
What is Acid Precipitation?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).

Hemophilia is a rare recessive genetic disorder in which the recessive version of the gene does not produce blood-clotting factors. A woman whose father had hemophilia marries a normal man. They have two children: a boy and a girl. What are the chances of the boy being a hemophiliac? _________ What are the chances of the girl being a hemophiliac? _________ Show your work with a Punnett Square.
Answer:25 , 0
Explanation:
XX©(mother being the carrier as her father was hemophilia- females can only be carrier of hemophilia ) when crossed with normal father produces offspring XX©, XY, XY©, XY. Therefore chances of boy being hemophilia=(1/4)*100=25.
Chances of girl being hemophilia= 0.

what is the importance of ATP and NADPH?
Answer:
The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
These electrons are used to produce NADPH as well as ATP in a series of reactions called the light reactions because they require light. NADPH and ATP formed by the action of light then reduce carbon dioxide and convert it into 3-phosphoglycerate by a series of reactions called the Calvin cycle or the dark reactions.

7. The _____________ is a collection of buried, long-dead organisms and can tell us information about prior ancestors - the _____________ a fossil is, the ______________ it is in age and the ___________ related it is to modern organisms.
Answer:
Fossil.
Explanation:
Fossil is a collection of buried, long-dead organisms that can tell us information about ancestors of an organism. The physical features of fossil provides information about its relationship with modern organisms. The fossil which is present in very deep in the soil are more older than the fossil that is present in less depth. We can find age of the fossil by using radiometric dating methods which tells us about the existence of fossil on the earth.

Describe the relationships among amino acids, chromosomes, proteins, and genes in the cells of a jackalberry plant. Make sure to include how gene expression is related to protein synthesis.
Answer:
The jackalberry plant is a multicellular organism whose cells contain chromosomes. The chromosomes contain genes that are transcribed to produce messenger RNAs, which are then translated into proteins
Explanation:
The Jackalberry tree is a plant, i.e., a multicellular organism. Multicellular organisms have chromosomes in the nucleus of each cell. A chromosome is a long DNA molecule that contains part (or even all) of the genetic information of a particular organism. Genes are specific segments of the chromosomes, which are expressed in a process called 'transcription' where a gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, these mRNAs are used to synthesize proteins by a process called 'translation'. In an mRNA molecule, each specific triplet of nucleotides is known as a codon and corresponds with a specific amino acid during protein synthesis. Thus, the mRNA sequence dictates the correct order of amino acids (i.e., the building blocks of proteins) in the polypeptide chain.

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.
In the presence of arsenate poisoning glycolysis is interrupted. ATP production proceeds via a reaction that involves 1,3-bisphosphoglycerate. a net production of 2 molecules of ATP occurs. All of the above None of the above
Answer:
glycolysis is interrupted.
Explanation:
The presence of arsenate can poison the process that inhibits ATP production which occurs during the process of glycolysis. Arsenate inhibits ATP formation during the process of glycolysis by substituting arsenate for the phosphate anion in a process known as arsenolysis. Arsenic has to inhibits cellular respiration by inducing mitochondrial enzymes and uncoupling oxidative phosphorylation.
