2. How does homeostasis
affect the body?

Explanation:

high temperature and low rainfall this leads to the need for adaptation to conserve water and tolerate extreme heat one of the main environmental pressures for cacti is water

Deforestation increases the risk of floods in an area tree roots improve soil water retention.

When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.

When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.

Thus, option "D" is correct.

Rapid mitotic cell division without growth, as seen in the first few divisions following the formation of a zygote, is called cleavage.

A zygote is the fertilized egg cell produced when a female gamete (egg, or ovum) and a male gamete combine (sperm). The zygote is the embryonic stage at which a genetically distinct organism emerges.  All organisms, with the exception of bacteria, reproduce sexually, and a common feature of this process is the joining of haploid gametes to create a diploid zygote. All of the components required for development are present in the zygote, but they only exist as an encoded set of instructions that are localized in the chromosome genes. The new zygote's genes do not actually begin to create proteins until several cell divisions after cleavage.

Explanation:

The limb bones are similar across these species because they share a common ancestor BEST explains this common skeletal structure.  

The three similar bone structures; humerus, ulna and radius that is found in the arm or forelimb of humans, horses, goats, and mice are known as homologous structures. These structures are found in different organisms and because of their similarity suggest that the organisms have evolved from a common ancestor. The structures are usually similar in form but they may not necessarily have the same function in the organisms.

Organ in which alcohol absorption occurs: Stomach and small intestine walls Blood stream Elimination of alcohol from the body: Liver

When a person drinks, the body absorbs alcohol, circulates it, and eventually eliminates it. Below are the organs or systems in the body where each of these steps takes place:

The organ in which alcohol absorption occurs: Alcohol is absorbed by the stomach and small intestine walls.

The bloodstream is where alcohol absorption occurs. The blood circulates throughout the body and transports alcohol from the stomach and small intestines to other parts of the body.

When alcohol enters the bloodstream, it is diluted, making it easier for the liver to break it down and eliminate it.

In addition, when alcohol enters the bloodstream, it may be found in all tissues of the body, including the brain, kidneys, lungs, and heart. The elimination of alcohol from the body: The liver is the primary organ responsible for metabolizing, or breaking down, alcohol.

Alcohol is eliminated from the body by the liver. The liver breaks down alcohol using enzymes that convert it to acetaldehyde, which is a toxic substance. The liver then converts acetaldehyde into acetic acid, which is a less toxic substance. Finally, acetic acid is broken down into carbon dioxide and water, which are eliminated from the body through urine and exhalation.

Yes, Carl will need to use a food web for the most accurate representation. A food web is a complex diagram that shows the network of relationships between different organisms within an ecosystem, including producers, consumers, and decomposers. It accurately shows the flow of energy through a system and how different species interact with each other. A food chain, on the other hand, only shows the transfer of energy from one species to another in a linear fashion, which doesn't accurately represent the complexity of a desert ecosystem.

Yes, Carl will need to use a food chain or a food web for the most accurate representation of the flow of energy in an ecosystem.

In most of the natural ecosystems energy comes from the sun, and it is consumed by the producer organisms. It is then passed on to the successive trophic levels in the form of food. Hence, the energy flows from the prey species to the predator species, not in the reverse direction.

A cloudy euphotic zone would affect phytoplankton by restricting their ability to obtain sunlight for photosynthesis. As a result, zooplankton could suffer from a reduced population of phytoplankton to feed on. Animals that rely on phytoplankton as a food source would also suffer when their population is low.

Organisms in the aphotic zone, which is beyond the reach of sunlight, are less likely to be affected by sediment clouds. The productivity in the affected area would decrease due to the limited availability of sunlight. The term "euphotic zone" refers to the vertical space and distance in the ocean water where sunlight can penetrate.

A cloudy euphotic zone would affect phytoplankton by restricting their ability to obtain sunlight for photosynthesis. Phytoplankton rely on sunlight as an energy source for photosynthesis, and a cloudy euphotic zone would limit the amount of sunlight reaching them, thus reducing their ability to carry out photosynthesis effectively.

As a result of this storm, zooplankton could suffer from a reduced population of phytoplankton to feed on. Zooplankton are dependent on phytoplankton as their primary food source. With a decrease in the population of phytoplankton due to limited sunlight, the availability of food for zooplankton would be reduced, potentially leading to a decline in their population.

Because phytoplankton are considered producers, animals that feed on them would suffer when their population is low. Phytoplankton form the base of the marine food chain as primary producers. When the population of phytoplankton decreases, organisms that rely on them for scarcity of their food source, impacting their survival and reproductive success.

Organisms in the aphotic zone will not likely be as affected by thick food, such as small fish and other zooplankton, would experience a clouds of sediment in the water. The aphotic zone is the region of the ocean where sunlight cannot penetrate. Therefore, organisms that inhabit this zone, such as deep-sea organisms, are adapted to survive in low-light or complete darkness conditions. They are not directly dependent on sunlight for their energy needs, so they are less likely to be affected by sediment clouds in the euphotic zone.

Productivity in this area would become reduced. With the limitation of sunlight reaching the euphotic zone due to sediment-rich runoff, the availability of energy for photosynthetic organisms like phytoplankton would decrease. As a result, the productivity of the area, in terms of biomass production and food availability for higher trophic levels, would decline.

The term "euphotic zone" accounts for vertical space and distance in the ocean water. The euphotic zone refers to the upper layer of the ocean where sunlight can penetrate, enabling photosynthesis to occur. It is the depth range where there is sufficient light for photosynthetic organisms to carry out their metabolic processes. The vertical extent of the euphotic zone varies depending on factors such as water clarity, turbidity, and the angle of the sun, and it plays a crucial role in determining the distribution and abundance of marine organisms.

Answer:

Ptolemy

Explanation:

Ptolemy is the earliest earliest astronomer and mathematician in the list who lived and worked in the second century AD. Nothing is known about his personal life but his scientific work is well known.

He made his observations using naked eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center.''(Khan Academy). His argument was that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.

Although Ptolemy made significant contributions in Astronomy but he was wrong in positing that the earth did not move at all. This is inconsistent with our present day knowledge about the celestial bodies. Also, his work missed out other planets that were yet to be discovered then such as Uranus, Neptune, Pluto etc.

After a few hours of incubation, you test the flasks for the presence of cAMP bound to CAP. Flask A (contains glucose) is a control and produces a low level of cAMP bound to CAP.

Flask B (contains glucose and lactose) produces the highest level of cAMP bound to CAP because the cells are glucose-depleted and lactose is present. Therefore, the correct answer is a&b: Flask A and Flask B. Flask C (contains lactose) produces a lower level of cAMP bound to CAP than Flask B because glucose is absent, and cAMP production is reduced in the absence of glucose.
