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

Sea surface temperature
Sea surface temperature is the measurement of the temperature of water closest to the surface of the sea/ocean. The image illustrates the effect of climate change on sea surface temperatures. The temperature has risen over the days in most part of the world from 1901 - 2015 due to change in climatic conditions caused by human and natural factors.

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.

Some giraffes have acquired longer necks by stretching to reach food and passed the trait to the D. Giraffes just started out with long necks and haven't changed.

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.

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.
