Which phrase best describes a point source of water pollution?
Answers
Pipe releasing wastewater from a paper plant describes a point source of water pollution.
What is Water Pollution?
Water pollution is defined as the release of toxic substances into surface and subsurface of water bodies such as oceans, seas, rivers, lakes etc. where these toxic substances interferes in the daily lifecycle of the natural functioning of ecosystem.
Water bodies can be polluted through different methods including pathogenic microorganisms, fertilizers releases and plants nutrients or release of the radioactive substances.
Pollutants enter the water environment from two main types of sources:
- Point Source
- Non Point Source
What is Point Source of water pollution?A point source as the name suggest is the single source of pollution which is specific and identifiable.
It is easy to identify and thus can be easily tracked and suitable actions can be taken to either reduce or prevent the pollution from point sources.
Example- Pollution cause through pipe discharge
What is Non Point Source of Pollution?A non point source of pollution is referred to that kind of pollution where there is no specific source and pollution is causing either from one specific source or through different sources.
It is also called as Diffuse Pollution and it impacts larger area.
It is often associated with particular land uses as opposed to point sources.
Example- Urban land use, Agricultural land use

A change in one base of the gene sequence is known as point mutation.
Explanation:
Question 2 is incomplete.
3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.
In Point mutations there is substitution of one base for another.
Example: TAT TGG CTA
TAC TGG CTA
The TAT changes to TAC which shows point mutation.
4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.
When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.

A species of fly can either have the dominant trait of red eyes, or the recessive trait of brown eyes. If one heterozygous fly mates with a brown eyed fly, what percentage of the offspring would you expect to have
Answers
Answer:
The correct answer would be -
50% heterozygous red flies and 50% recessive brown eyes flies in offspring
Explanation:
This is given that a species of fly has two traits for the eye red eye which is the dominant trait and can be represented by R and the brown eyes trait which is recessive and represented by r.
Given: heterozygous fly which means have both traits gene but as Red is dominant it will have red eyes mates with recessive brown eye fly.
Rr × rr
gametes: R, r and r, r
then,
R r
r Rr rr
r Rr rr
There is 50 % recessive brown eyes flies in offspring and 50% heterozygous red eys offspring.

Tim scraped his knee during a fall and it needs to be repaired. The closest skin cells begin sending out growth factors through paracrine signaling to tell all nearby skin cells to start replicating to repair the damaged area.
What are the next steps once the message is sent?
A) The growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells start dividing.
B) The growth factors are packaged into a vesicle and secreted from a cell that acts upon target cells near and far. The cells start mitosis.
C) The growth factors are packaged into a vesicle and secreted from a cell that acts upon only a target nearby cell. The cell starts swelling up.
D) The growth factors are packaged into a vesicle and embedded into the plasma membrane where it is detected by other cells. The cells produce more proteins.
Answers
Answer:
It is B all the other answers are for other types of injuries, knee scrapes don’t swell, it might divide, and it would produce more protein
Explanation:
Tim scraped his knee during a fall, and it needs to be repaired, so the growth factors are packaged into a vesicle and secreted from a cell that acts upon target cells all nearby cells. The cells start dividing, which is present in Option A.
What happens during cell repair?When the cell breaks, then the nearby cells release the paracrine signaling that goes to the cells and stimulates the cells to make the mitosis process and divide, which includes DNA replication, protein synthesis, and RNA synthesis, and then from the original cells, the daughter cells are formed and fill the gap that is formed in the injury and the far cells don't get the signal as the paracrine factors acts nearby.
Hence, Tim scraped his knee during a fall, and it needs to be repaired, so the growth factors are packaged into a vesicle and secreted from a cell that acts upon all nearby cells. The cells start dividing, which is present in Option A.

Answers
Answer:
A wetter climate slows the rate of transpiration allowing for there to be more stomata present on each leaf. Plants lose a lot of water when they open their stomata to get carbon dioxide for photosynthesis, especially in hot, dry deserts. Cacti lose less water by only opening their stomata at night.
