Which phrase best describes a point source of water pollution?
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

Answer:
C. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on.

What is the phenotype of a person whith the genotype I^Ai?
Answer:
Type A
Explanation:
Mode of inheritance for blood is tricky, but type A and B are codominant, while type A and type B are dominant over O. So in this situtation
I^Ai is A because type a is dominant over o
in wetter climates plants usually have more stomata and grow faster. Suggest why
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.

Explanation:
This tall, branching saguaro cactus provides nesting sites, food, and water
to other animals of the Sonoran Desert.
Which term best characterizes the role of the saguaro cactus in its desert
ecosystem?
The term biotic factor best characterizes the role of the saguaro cactus in its desert ecosystem.
What is an Ecosystem?An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, space, and shelter.
Saguaro cactus provides nesting sites (space), food, and water to other animals of the Sonoran Desert and allows them to survive and reproduce in a much better way. This refers to the biotic factor of an ecosystem.
Therefore, the term biotic factor best characterizes the role of the saguaro cactus in its desert ecosystem.

How is salinity affected when precipitation increases
Answer:
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

Which statement is true regarding meiosis in cells?
O In anaphase I, sister chromatids are pulled apart at the centromere.
O In prophase II, homologous chromosomes are paired up in a tetrad.
O The daughter cells do not undergo cytokinesis at the end of meiosis
The products of telophase I are two haploid daughter cells..
answer : the last one is true, yeah !!
d :: the products of telophase 1 are two haploid daughter cells ..
Chromosomes finish migrating to opposing ends of the cell in telophase I. Cytokinesis then creates two daughter cells. Therefore,option (D) is correct.
What happens is telophase I?The parent cell has two poles at Telophase I of the meiotic cycle, each with a full complement of haploid chromosomes (which still have their sister chromatids). Now, a cleavage furrow forms, separating the cytoplasm of the cell in two (a proccess ultimately called cytokinesis).
The homologous chromosomes divide into distinct nuclei during telophase I. The cell restores its nuclear membrane, deconstructs the microtubules and spindle fibers, and then initiates cytokinesis. After then, the cell enters a phase of rest known as interkinesis.

Populations can have variety, despite being made up of
the same species. If a population has different expressed
traits, this can be due to different inherited alleles. The
frogs below are the same species, but they have different
shades of green based on their inherited alleles. In a
particular environment, lighter green frogs are easier to see
by predators. Explain how natural selection could lead to a
change in allele frequency.
Answer:
The lighter frogs will be eaten and will not be able to reproduce offspring with the light green trait. Darker green frogs will be able to reproduce more dark green frogs. Eventually most/all frogs will be a darker green because they carry a trait that improves chances of survival.

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.
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.

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
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.
