Which best explains why all of the Earth’s freshwater is not available for human use?
Answer:
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
Explanation:
99% of liquid freshwater on Earth is Stored as Ground water
Much of it probably isn't accessible to us Human.
About 71 % of Earth is covered in water, and the Ocean holds most of it but this is salt water, almost all fresh water is stored underground

Which of the following mixtures forms a solution?
A. melting ice
B.
sand and water
C. boiling water
D. alcohol in water
Answer:
D. alcohol in water
Explanation:
All the other answers do not form a solution. Melting ice, as well as boiling water, is still pure water. Sand and water are two different substances, however, sand does not dissolve in water to create a homogeonous solution, leaving alcohol and water, which DO combine into a homogeonous solution.

Identify ONE process that causes the metamorphism of an igneous rock into a metamorphic rock.
Answer:
Heat
Explanation:
Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.
Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.
What is metamorphic rock?Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.
Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.

7. An extremely rare X-linked recessive genetic disorder known as Norrie disease affects the eyes
and can lead to blindness and in some cases hearing loss. There are only 400 known cases of
Norrie disease worldwide. Explain why it is virtually impossible for a baby girl to be born with
Norrie disease.
Answer: Girls need to inherit two affected chromosomes to develop the disease, and it may also happen that the affected chromosome is inactivated in the eye (if it has only one)
Explanation:
Norrie's disease is an inherited eye disorder affecting males, which is characterized by abnormal or immature development of the retina (light-sensitive nerve tissue lining the back of the eye) and possible deterioration of the iris (colored part of the eye) and eyeballs. X-linked recessive inheritance is one of the ways in which a genetic trait or condition is passed from parent to child when there are mutations in a gene on the X chromosome from either the father or the mother. Females possess two X chromosomes, while males possess one X and one Y chromosome. In males, the presence of a mutation on the X chromosome causes the disease, since it is the only X they possess. In females, both X chromosomes need to be affected if it is a recessive condition.
So, the disease is inherited in an X-linked recessive manner, which means that almost all affected individuals are male. However, the sons of affected males will not have the mutation since they only inherit the Y chromosome, while all their daughters will be genetic carriers of the mutation because they inherit the affected X chromosome, although without clinical symptoms but being carriers. On the other hand, the mother will pass one of her two X chromosomes (which may or may not be affected) randomly to both her male and female offspring (if they are male, they will be affected and if they are female they will be carriers unless they also inherit an X chromosome from their father). So the only way for females to develop the disease is for their two copies of the gene to be mutated if both parents have the mutation.
But female carriers could be affected by inactivation of their X chromosome with the correct sequence. X chromosome inactivation is a random process that happens separately in individual cells during embryonic development. That is, one cell may inactivate the paternal X chromosome, while others may inactivate the maternal X chromosome. This is because a dosage compensation is necessary, since the Y chromosome in males is not homologous to the X, it does not have the same genes, so if females would express both X chromosomes, they would have twice as many genes as a male. All the descendant cells of each of these original cells will maintain the same pattern of X chromosome inactivation.
In females, one X chromosome is inactivated in each tissue in an arbitrary manner. Then, in addition to having to inherit two affected chromosomes, it may also happen that the affected chromosome is inactivated in the eye (if it has only one).

40. What characteristic of the yeti crab contributes to its name?
-It is mentioned in mythology.
-It is covered with setae.
-It is found in the Himalayas.
-It is larger than other crabs.
Answer:
-It is covered with setae.
Explanation:
The yeti crab is given the name Yeti as it has hairs on its legs and thus resembles those of the yeti that lives in the snow-capped Himalayas. The crab has been know to be discovered during the southeastern pacific expedition of the microplates. Satae is a type of hair that grows on the body of animals or organisms. The crab is noticeably 15 cm long and the fur covers the legs and claws.Who is known as the father of Natural selection?

Which of the following describes an impact of floods on ecosystems?
Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.
Ouch. You step on a tack and jrk away without even thinking. Then you decide to pick up the tack and put it on your desk. Which body systems are involved?
Answer: The body systems that are involved are:
--> Nervous System and
--> muscular system.
Explanation:
The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:
--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.
--> The muscular system: This system enables the organism to move from one location to another.
Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.
The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.

How are the Hawaiian honeycreepers an example of adaptive radiation?
There were a large variety of honeycreepers that first inhabited the island. They found many different niches, so they were all able to survive.
The honeycreepers that first inhabited the island were able to adapt as the island changed, so that population of birds was able to survive.
There was a diversification of honeycreepers (each with different beak shapes) to help fill various ecological niches.
Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.
