Waterborne pathogens can enter coastal waters via leaking sewer pipes and untreated wastewater.
Sewage and untreated wastewaters are filled with microbes some of which are capable of causing diseases to humans and livestock if given the opportunity. Hence, the seeping of these waters into coastal water is a risk to humans who might want to swim or make use of coastal waters.
Precipitation, changing of tides and the interactions of marine organisms and plants will ordinarily not form pathways through which pathogens can gain access to coastal waters.

Draw the basic structure of a nucleotide with its three parts.
Answer: This picture has the answer
Explanation:
The nucleotides which are found in the DNA molecule are made up of nucleoside moieties and phosphate molecule. These are of five types which include adenosine, guanosine, uracil, thymine, and cytosine.
What is a nucleotide?Nucleotides are the organic molecules which consist of a nucleoside and a phosphate moiety. The nucleotide molecules serve as the monomeric units of the nucleic acid polymers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all life forms on the Earth.
A nucleotide is one of the main structural components, or the building blocks, of DNA and RNA molecules. A nucleotide consists of a base which has one of four nitrogenous base which could be purine and pyrimidine such as adenine, thymine, guanine, and cytosine plus a molecule of sugar and one molecule of phosphoric acid.

in turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, what is the probability of an individual offspring having yellow feather?
50%
0
25%
100%
Answer:
50%
Explanation:
trust me because the heterozygous is so weird but I know this.
In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.
What will be produced in turkeys a dominant gene?In turkeys a dominant gene, R, produces the familiar bronze color; its recessive allele, r, results in red. Another dominant gene, H, results in normal feathers; its recessive allele, h, produces feathers without webbing, so that they resemble tufts of hairs.
Two bronze turkeys with normal feathers were mated, and their offspring consisted of eight bronze with normal feathers, three bronze with hairy feathers, two red with normal feathers, and one red with hairy feathers.
Since, this offspring received a recessive red, r, allele from each parent and a recessive hairy, h, allele from each parent, both parents must heterozygous for both characters: RrHh.
Therefore, In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.

What happens to the states of matter when the temperature changes
They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)
If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)

Answer: If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will D. complete the cycle and divide. G1 checkpoint occurs between the G1 and S phase of the cell cycle. When the cell is grown sufficiently and produces all components of DNA replication it enters in the S phase.
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide.
What is cell cycle?The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.

Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?
Group of answer choices
A. Antibodies in the vaccine provide the body with nonspecific immunity to an antigen.
B. Fever and swelling develop which is the first response in killing a pathogen.
C. An inactivated or killed virus stimulates the body to develop specific immunity to that type of virus.
D. Heathy bacteria causes the body to release toxins which will protect the body if later exposed to different type of bacteria.
Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

PLEASE ANSWER ASAP.
Explain what friction, corollas, and a low pressure gradient does to an air parcel. IF YOU CAN PLEASE GIVE A SHORT ANSWER.
Answer:
sorry big answer Answer with Explanation:
Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.
Air parcel - refers to a body of air that is "imaginary."
Pressure gradient - the change in pressure across a given distance.
Pressure gradient force - the net force that is being directed from high pressure to low pressure.
When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.
However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.
Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."
When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.
