Answer:
physiologist
Explanation:
A physiologist is a person or a professional who studies and does experiments to see the function and behavior of plants and animals under normal circumstances as well as abnormal circumstances. They also study and learn the impact of the human life on the species and how the specimens they interact with each other.

Humans now use drained salt marshes exclusively for agriculture. c. Humans have begun to use salt marshes for landfills. d. Humans have begun to use marsh land for housing and commercial development.
Answer:
. Humans have come to value salt marshes and now seek to preserve and restore them
This is the portion of a wet land that is constantly flooded by tides,,and as the salt water carried by the tide regresses, it drained this portion of land leaving a wet land.This wetland is called salt mashes.They are ubiquitous,in the estuary habitat.
The soil layer is mostly of deep mud and peat.The latter contain decomposing plant material carried by the tide.The oxygen level is usually low,due to activities of bacteria abundant in the soil.Its vegetation contain some covered grasses,herbs,and shrubs,because the constant flooding depleted the soil nutrients.
Humanity has come to realized that these wetlands has some benefits
1.it Protect the shorelines from being washed away by erosion.This is because it reduced the momentum of erosion by buffering the effect of the waves,reducing it speed and therefore reducing the damaging effect of the erosion.,
It also reduces flooding by reducing run off, by allowing rain water to sink deep,therefore prevent stagnancy of water on the soil surface, slowing down the pace,which would have removed the topmost layer containing nutrients
It also improve the quality if water available,because he debris carried the tides serve as the sever to filter the water,separating sediment,improving quality.

Which of the following pH levels will most likely NOT affect enzyme activity
7
3
12(high ph)
2 (low ph)
Answer:
7
Explanation:
It is a neautral pH (pure water has a neautral pH).. Every enzyme works at an optimum pH and different enzymes work best at different pH.
The pH levels that will most likely NOT affect enzyme activity is 7
Enzymes are those soluble proteins found in the body which help in food digestion.
Enzymes are sensitive to the acidity or alkalinity of their environment.
Some enzymes require an acidic medium which is from 0 to 6 in the pH scale while some require an alkaline medium which is from 8 to 14 in pH scale.
Also some enzymes work best in neutral medium which is at pH 7.
However, enzymes are highly affected in extreme pH such as 1, 2, 3 ( low pH indicating high acidity) and 12, 13 14( high pH indicating high alkalinity).
This is because bonds holding the complementary active site of an enzyme break at extreme pH, preventing substrates from binding to it.

How can resource conservation benefit the environment?
A. Resource conservation can help preserve natural habitats.
B. Resource conservation can reduce water pollution.
C. Resource conservation can reduce air pollution.
D. All of the above
Answer:
D is the right answer
Explanation:
By conserving resources, we can protect the air, water, and land for future generations. It doesn't take much effort to use less water, electricity, and other resources at home and work. With small changes, you can have a significant impact on creating a more environmentally friendly world.
Resource conservation can benefit the environment in the following ways:
Resource conservation can help preserve natural habitatsResource conservation can reduce water pollution Resource conservation can reduce air pollutionWhat is resource conservation?Resources are substances used to achieve a goal or objective. They can either be natural or artificial.
However, during the process of using these resources, a lot of damage can be done on the environment, hence, compromising sustainability.
The conservation of resources i.e. wise use helps reduce the risk of pollution or negative effect on the environment.

Answer: The answers seem correct.
1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.
2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.
3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.
Explain why the plants from year 2-4 may not be
present in year 25-50
Answer:
ecological succession.
Explanation:
The plant may not be present in 25-50 years due to ecological succession. in ecological succession, the vegetation such as small plants that is present replaces by the more suitable vegetation such as trees because the vegetation (small plants) did not receive nutrients and sunlight so they are unable to grow and finally dies due to lack of basic needs. So that's why plant may not be present 25-50 years.

The community of the animals and the plants along the abiotic factors is called an ecosystem. New plants can benefit the species and the invasive can harm the species.
What are the effects of the plant introduction in an ecosystem?The introduction of new plant species in an ecosystem affects the ecosystem and the species habiting the area as it can become part of their chain if gets adapted to the area.
The introduction of the non-native or invasive species will harm the organism of the ecosystem as they can be harmful or toxic for the organism living there and hence, reducing their population.

The Earth is made up of 75% water. Sources such as oceans, lakes, and
rivers have an important role in keeping Earth's surface insulated and
warm. What property of water provides this protection?
O Ability as a solvent
O Cohesion
Hydrogen bonds
O Specific heat
Answer:
The correct answer is - specific heat.
Explanation:
Water has an important property named specific heat, which is an amount of heat required to increase the temperature of a given amount of a substance. So, to increase the temperature of 1 g water to one degree, the amount of heat is required is the specific heat of the water.
Specific heat helps in regulating the change in temperature of the earth due to its requirement of a proper amount of heat to increase the temperature of water to extent of boiling similar happen in colling as it is required to release a proper amount of heat.
Thus, the correct answer is - specific heat.

After exercise, capillaries close to the surface of the skin become
; this process is called
. More blood supply goes through the capillaries so more heat is lost from the
.
Answer:
Body temperature is monitored and controlled by the thermoregulatory centre in the brain. This centre has receptors sensitive to the temperature of the blood flowing through the brain. If the core body temperature is too high, the thermoregulatory centre causes the blood vessels supplying the skin capillaries to expand so that more blood flows through them. Since the blood flows through the entire body, it can take the excess heat from the core of the body to the skin, where it can be lost. When a blood vessel of any sort increases in diameter, we say that it dilates. Because the dilation is related to the vascular (blood) system, this process is called vasodilation.
