In an experiment the setup that provides the basis of comparison is known as

Surface water (rivers and lakes) are the most available source of fresh water. The other sources of fresh water are largely unavailable.

Water on earth could be fresh water or salt water. The difference between the two is that freshwater is not salty. There is a limited quantity of available freshwater on earth.

Fresh water is found in glaciers, surface lakes and rivers and groundwater.The order of decreasing availability of fresh water on earth is ice> Groundwater > lakes and rivers (surface water).

Unfortunately, the source of freshwater that can easily be obtained for human use is surface water (lakes and rivers). There is only about [tex]1\frac{2}{3}[/tex]% available freshwater in rivers and lakes. About 87% of the world's fresh water supply is locked away in glaciers.

Given the limited availability of fresh water sources, the possibility of an water challenges in the world can not be over emphasized. Definitely, there may not be enough water in the future hence water conservation efforts must be taken seriously.

Stem cells are typically found in that of babies, because they can become anything the body needs. Such as when a pregnant person has been hurt the baby inside will send stem cells to the injury to help repair what was damaged. Many people think that by retrieving stem cells they can be used to   assist in recovery of people with regeneration of blood vessels and nerves and or even cure Alzheimer's.

Explanation:

Blood concentration is approximated by the distance from the source.

The concentration of blood at a point P(x,y,z) on the surface of sea water is approximated by the distance from the source where the blood moves. Point x is the place where the concentration of the blood is the highest because at this point the source of blood present.

At point y, the concentration of the blood is lower as compared to point x but higher than point z, while on the other hand, at point z the concentration of blood is the lowest due to its presence farther from the source so we can conclude that blood concentration is approximated by the distance from the source.

In order for an organism to decompose to the point that only dry bones will remain, it is estimated that in warm and humid environments the process will take roughly three weeks, In which case the options of Days 26-43 as well as after day 50 are correct.

Decomposition is what happens to any dead organic material. Decomposition is when the organic material is broken down into smaller compounds, organic or not. This process is affected by a variety of conditions including:

and so on. Each of these factors can greatly impact how fast something will decompose.

The question at hand gives us the conditions for the fastest decomposition, given that this process is accelerated in warm and humid conditions. When in these conditions, it is estimated that an organism can take a minimum of three weeks to reach the stage in which all that is left is the skeleton (dry bones).

Three weeks consists of 21 days, however, option 6 that states "Days 18-25" is not being included given that during days 18-21, elements other than bones may still be present. For this reason, the correct answer is any day after day 21, that is, days 22-50+. Therefore, options 5 and 3 can both be considered correct as in those days only dry bones will remain.

Color of seeds Mendel chose to cross

Explanation:

This variable does not depend on the other variables you are trying to measure, so it is independent.

In Gregor Mendel cross, the variable does not depend on the other variables you are trying to measure, so it is independent.

Mendelian Crosses: In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation).

Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.

A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.

Limit fishing around reefs would not help to protect the diversity of coral reefs.

Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs. 

Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.

Coral polyp colonies are bound together by calcium carbonate to build reefs.

According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.

The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.

Hence the correct option is B.

Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.

Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).

Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.

Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.

How is the shape and size of red blood cells related to their function?

This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. Many RBCs are wider than capillaries, but their shape provides the needed flexibility to squeeze through.
