How can a population grow?
Answer:
The population of the world is continuously growing. This not just causes over-population but reduces employment rates. Not only the population itself was growing, but also the doubling time was decreasing, which basically means that growth itself was growing. This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age.

Predict what would happen if the cytoplasm of the cell is dysfunctional?
The cell will keep doing its normal activity as long as it contains a nucleus.
The cell will not be able to access chemical substances that it needs to function.
The cell will lose its nucleus.
The cell will not be able to reproduce to create an identical cell.
Answer:
The cell will not be able to access chemical substances that it needs to function
Explanation:
Without cytoplasm, all there is in the cell is the nucleus, so the cell can't perform maintenance or make energy, or function at all. Without cytosol, there would be no medium in the cell for the organelles and solutes to move through.
If the cytoplasm of the cell is dysfunctional, the cell will not be able to access the chemical substances that it needs to function. The correct option is B.
What is cytoplasm?The gel-like substance that fills a cell is called cytoplasm. It serves as a catalyst for chemical reactions. It offers a foundation for other organelles to function within the cell.
A cell's cytoplasm is where all of the processes for cell division, growth, and replication take place. The only component of a cell other than the nucleus without which it cannot perform maintenance, produce energy, or otherwise operate is the cytoplasm.
There wouldn't be a medium in the cell for the organelles and solutes to pass through without the cytosol.
Therefore, the correct option is B. The cell will not be able to access the chemical substances that it needs to function.

Explanation:
Without adequate protein, children and teens' physical growth and brain development may be stunted.
A.
True
B.
False
Answer: the answer is true/a
Explanation:
Children who are malnourished–not just fussy eaters but truly deprived of adequate calories and protein in their diet–throughout this period do not adequately grow, either physically or mentally. Their brains are smaller than normal because of reduced dendritic growth, reduced myelination, and the production of fewer glia (supporting cells in the brain which continue to form after birth and are responsible for producing myelin). Inadequate brain growth explains why children who were malnourished as fetuses and infants suffer often lasting behavioral and cognitive deficits, including slower language and fine motor development, lower IQ, and poorer school performance.
A baby’s birth weight–and brain size–do depend on the quality of his or her mother’s nutrition during pregnancy. Pregnant women should gain about 20 percent of their ideal pre-pregnancy weight (e.g., 26 pounds for a 130-lb woman) to insure adequate fetal growth. This requires consuming an extra 300 calories per day, including 10-12 extra grams of protein.

5. After a signal is transmitted from the eyes through the optic nerve, which part of the
the visual information?
O A. The frontal lobe
O B. The occipital lobe
OC. The limbic lobe
OD. The temporal lobe
Answer:
The answer is B. The occipital lobe.
Explanation:
The brain receives signal or information for vision through one of the five senses, the eyes. The brain processes the visual information in the occipital lobes of the cerebrum. The occipital lobes are one of the four main lobes of the cerebral cortex. The eyes transmit this information to the visual cortex. The visual cortex takes processes the information so, we are able to see the things.

What do you call the stronger genes expressed in the hybrid, represented as capital letter?
Dominant Genes;
Because they are most likely to be expressed, when it goes between a dominant and a recessive gene (Hh), H would be expressed while h would just be carried.
Dominant Genes are stronger genes expressed in the hybrid.
What are dominant genes?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
How do you determine dominant genes?Dominant alleles are seen as an uppercase of a letter; for example, B. Recessive alleles are seen as a lower case of a letter; b. In order for a person to show the dominant trait, one of the person's parents must have the dominant trait (which is an uppercase letter).

Place the following concepts in the correct order to explain how you can get shocked
after walking across the floor and reaching out to touch a doorknob or other object.
large electrical potential difference, induction, conduction, charging by
friction, static discharge
b)
none of the above
charging by friction, induction, large electrical potential di..vrencu, static
discharge
O d) induction, large electrical potential difference, conduction, repulsion
e) charging by friction, induction, conduction, static discharge
Answer:
The correct answer is option c.
Explanation:
When someone walking across the floor the friction is the concept that works in between the feet and floor or rug or carpet which makes the exchange between floor to the person. Now the body of an individual has a static charge at the moment.
When the person touches the doorknob or any metal, electrons move from the body of that individual to the handle or knob through the fingertips as static discharge due to the electrical potential difference and the person gets an electric shock.
Thus, the correct answer is option C.
When NAD+ becomes NADH, it is being
NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.
Explanation:
When NAD+ becomes NADH, it is being reduced.
What is NAD+ and NADH?NAD+ is a coenzyme that is involved in many metabolic reactions. It is a dinucleotide, meaning that it is made up of two nucleotides. The nucleotides are nicotinamide adenine dinucleotide (NAD) and adenosine diphosphate (ADP).
NAD+ is oxidized when it loses an electron. This leaves the nicotinamide ring with an extra hydrogen atom, which gives NADH its name. NADH is a reduced form of NAD+.
The reduction of NAD+ is a necessary step in many metabolic reactions. For example, NADH is used in glycolysis, the process by which cells break down glucose to produce energy. NADH is also used in the Krebs cycle, the process by which cells break down carbohydrates, proteins, and fats to produce energy.

There appears to be some relationship between population density and the presence of large dead zones. Can you explain why dead zones seem to be more prominent in areas of high
population density
Nitrogen and phosphorus runoff from sewage and agricultural activities in high population centers leads to the formation of dead zones.
People in these high population areas have over fished their coastal waters, leading
dead zones
The abundance of cruise ships in these high population centers results in the production of large amounts of pollution, leading to the formation of dead zones.
This is a random correlation and not a result of population centers causing the dead zones
Answer: Dead zones can be defined as an area of significant pollution.
Explanation:
Dead zones are associated with waters with low-oxygen content and the organisms suffer from hypoxic conditions. These areas include the waters of oceans, lakes and other types of water bodies.
The dead zones are created due to human activities. The high density population of human kind require space to survive. They use and contaminate the nearby source of water body. The agriculture pollutants contains fertilizers and pesticides which contains nitrogen and phosphorus that runoff into the water body. Also the sewage discharge also increases the nitrogen content in nearby source. Thus makes the water body oxygen deficient.
The large population of human kind may depend on fishery as source of food thus they may create a dead zone in nearby water body by overfishing and depleting the population to a level of zero.
The cruise may introduce oil contaminants in the water body which can reduce the oxygen availability of the water hence, kill the organism and create a dead zone.
Answer: Nitrogen and phosphorus runoff from sewage and agricultural activities in high population centers leads to the formation of dead zones.
