The factor in the Southwestern desert ecosystem that is abiotic is precipitation.
What are abiotic factors?Abiotic factors are the non-living components of an ecosystem influencing the living organisms' distribution in an area. Precipitation is an abiotic factor that provides water for plants and animals to survive and is a very important part of the ecosystem.
In the Southwestern desert ecosystem, the low precipitation levels resulted in an arid environment which results in the presence of a unique array of plant and animal species that have adapted to survive in these conditions.
Temperature is also another important abiotic factor in the Southwestern desert ecosystem. The high temperatures during the day and low temperature at night influence the behavior and survival of the animals and plants that live in this environment. Wind patterns, soil type, sunlight, etc. are other abiotic factors.
Therefore, the factor in the Southwestern desert ecosystem that is abiotic is precipitation.

1. Explain the factors that
have contributed to an
increase in the survival rate
of the human population.
How have these factors
contributed to the
homeostasis of the
population within its
environment? Explain.
Answer:
I am answering just from my knowledge
The factors that have contributed to an increase in human population are two main e.g Increase in birth rate and decrease in death rate.
Increase in birth rate is due to more food production and food supply.Massive increase in agricultural productivity.More life expectancy etc.There is a decrease in death rate beacauseof eradication of diseases,better hygiene,cleanliness and development in medical facilities. Similarly, populations of organisms respond to external factors for a collective benefit. All populations must have an adequate amount of food, water, shelter, and space. ... Biotic factors like predation and competition for food are also limiting factors.the technologies used to achieve this transformation have caused unprecedented changes to Earth’s environment, altering ecosystems to the point where some may be in danger of collapse. The depletion of the ozone layer, erosion due to acid rain, and damage from global climate change are caused by human activities. The ultimate effect of these changes on our carrying capacity is unknown. As some point out, it is likely that the negative effects of increasing carrying capacity will outweigh the positive ones—the world’s carrying capacity for human beings might actually decrease.good luck
The factors that have contributed to an increase in the survival rate of the human population are natality, mortality, immigration, and pathogens presence.
What do you mean by Survival rate?Survival rate may be defined as the time duration in which a particular organism survives from their birth to death.
Natality is the number of individuals born in a specific period of time, mortality deals with the number of dead individuals, and immigration means the entry of other individuals into a particular location. Apart from all these one factor i.e. pathogen presence also affects the survival rate of human population to a large extent. That we all see during corona virus times. All these factors contributed to the homeostasis by maintaining an equal degree of balance inside as compared to the outer environment.
Therefore, the factors that have contributed to an increase in the survival rate of the human population are natality, mortality, immigration, and pathogens presence.

Explanation:
A dehydrated person enters the hospital. The traditional procedure to treat a dehydrated patient is to add saline (salt) solution to their blood. Saline solution is a mixture of salt (solute) and water. However, the nurse accidentally gives the patient distilled (pure) water. What will happen to the person's cells?
Answer:
The cells will taking-in water and hemolyse
Explanation:
If water is given to dehydrated patients instead of a saline solution, the cells of the patients will take-in water from the surrounding solution by osmosis because distilled water is hypotonic to the red blood cells. The cytosol has a higher concentration of solutes than distilled water. When this happens, the cells become turgid and burst out its contents, a condition known as hemolysis.

What is the function of the valves within the heart and veins? to ensure the production of blood within the body to ensure coordination of the heart cells for pumping blood to ensure that foreign materials do not enter the heart to ensure that blood flows in one direction only
Answer:
to ensure that blood flows in one direction only
Explanation:
Here, we want to select which of the options is the function of valves within hearts and veins.
Basically, valves serve as control mechanisms in the circulatory system.
By control, it means that they actually dictate the direction in which the blood will flow.
Hence, valves ensures that blood types which is supposed to flow from the heart does not flow towards it and blood types that are meant to flow towards it does not flow away from it
An example of this can be seen in the case of oxygenated and deoxygenated blood.
Both have different flow mechanisms which are controlled by the actions of the valves
Answer:
D. To ensure that blood flows in only one direction

How does heat transfer between the atmosphere and the ocean affect regional climate?
Explanation:
Both the ocean and the atmosphere transport roughly equal amounts of heat from Earth's equatorial regions - which are intensely heated by the Sun - toward the icy poles, which receive relatively little solar radiation.
The ocean and atmosphere are constantly in a process of energy exchange (heat transfer) as the ocean bodies serves as heat trap which absorbs the larger portion of the Sun's radiation, which is distributed to surrounding areas as sunlight subsides, with the ocean water also losing moisture due to evaporation.
Areas very close to the ocean, topical regions experience the highest level of evaporation and they inturn experience the highest amount of Rainfall. Hence, dictating the regional climate of the tropics.
Ocean currents also play a major role in ensuring distribution of heat, precipitation and warmth between the equatorial and tropical regions, Hence, patching a sort of balance in regional distribution of heat and Rainfall.

Describe organisms that are able to produce enough energy for life processes with no oxygen available.
Answer:
Plants
Explanation:
Plants turn carbon into oxygen....
Organisms that are able to produce enough energy for life processes with no oxygen available are - prokaryotic organisms such as some bacteria and archaea and eukaryotic organisms such as yeast and lactic acid formation in mammals.
Oxygen is essential for most of the time in the production of energy However, many organisms carry out metabolism without oxygen, or can switch from aerobic to anaerobic cell respiration when oxygen is absent.
Fermentation is a process that uses an organic molecule to regenerate NAD+ from NADHAnaerobic cellular respiration is a process that uses either inorganic molecules or organic molecules to accept electrons.prokaryotes use anaerobic respiration. For example, the group of archaea called methanogens reduces carbon dioxide to methane to oxidize NADH.Thus, the correct answer is - prokaryotic organisms and some eukaryotic organisms.
