Oil spill or a discharge from pipe from a factory or sewage system. Since this is a single point of origin water pollution, this type of water pollution furnish itself to relatively easy remediation.
What is point source water pollution?
Point-source water pollution is the one type of water pollution which is easy to recognize because it generates from a single source or event and affects a specific area.
The negative effects of single point origin is deteriorating water quality which damage the environment, health conditions.
Destruction of biodiversity is another negative effect of water pollution depletes aquatic ecosystems and prompt unbridled proliferation of phytoplankton in lakes called as eutrophication.
The solution to reduce water pollution is reduce carbon dioxide emissions to prevent global warming and acidification of the oceans. Another is to reduce the use of chemical pesticides and nutrients on crops.

Describe how increasing light intensity affects the rate of photosynthesis.
As light intensity increases in photosynthesis so does the rate of photosynthesis. The more light there is the more photosynthesis in the thylakoid membrane is activated. However, the light intensity can only increase up to a certain point before the rate of photosynthesis no longer increases. Once there is a sufficient intensity of light, the ATP and NADPH that come from the light reactions will be in abundance. For the remaining part of photosynthesis to occur (the Calvin cycle), carbon dioxide is needed.

DNA is a nucleic acid molecule that undergoes a replication process to form a new daughter strand. The blue segment is the parental strand, and the yellow is the daughter strand.
What is replication?Replication is the process of the central dogma that duplicates the copy of the parent strand into new daughter strands. The two helixes of the parent strand get separated to make the complimentary copy of the new strand.
The daughter DNA is semi-conservative and are complementary structure made from the duplication of the parent strand with the help of the replication enzymes.
Therefore, the daughter strands are the semi-conservative copies of the parental strand.

5. A mother's diet is very important throughout her pregnancy but especially during the first
trimester. Vitamins and minerals provide essential nutrients during this stage of
development. Vitamins A, D, and Beta Carotene help bones and teeth grow and harden,
Vitamin E is used in the formation of red blood cells and muscles, and Vitamin C helps build
a healthy immune system. Which of the following would most likely result from a poor diet
during the first trimester?
A. Less production of urine
B. Response to outside stimulus
C. A functioning nervous system
D. Abnormal development of the heart and lungs
Poor nutrition during the first trimester of pregnancy can have negative effects on both the mother and the unborn child. A poor diet is more likely to cause improper heart and lung development.
What is the dependence of the bones ?The growth of bones and teeth depends on vitamins A, D, and beta-carotene, whereas the development of red blood cells and muscles depends on vitamin E. A robust immune system may be built using vitamin C.
Without these nutrients, the baby's heart and lungs could not develop normally, which might result in life-threatening medical issues. Because the body is unable to absorb the essential nutrients from meals, poor nutrition can also result in reduced urine output.
Dehydration from this may result, which may further contribute to healthcare issues. Additionally, because the baby's nervous system could not be fully formed, a poor diet during the first trimester can result in a diminished reaction to external input.
Problems with motor and cognitive development may result from this. To sum up, a bad diet throughout the first trimester might result in major medical issues for both the mother and her unborn child. A poor diet is more likely to cause improper heart and lung development.
In addition, a poor diet might cause issues with motor and cognitive development, reduced sensitivity to external stimuli, and decreased urine output. It is therefore essential that pregnant women eat a balanced diet with the necessary vitamins and minerals to ensure the health of both mother and baby.

Construct a family pedigree of two unaffected parents with a grandson who suffers from sickle cell disease.
KEY:
Yellow = CarrierGrey = Not a carrier and not affectedBlue = AffectedReasoning:
If you take a close look you can see that the child affected by sickle cell has a sister who is not affected, and you may be wondering why. Well, this is because sickle cell is a s3x linked trait, X and Y chromosomes. And you know that males have one X and one Y, while females have two Xs.
Sickle cell is inherited by the X chromosome, and since males don't have two of those chromosomes then if their X chromosome is faulty, they don't have a back up chromosome, unlike women. For a woman to have sickle cell, she would have to have two faulty X chromosomes inherited by both of her parents.
