Answer:
Question 1=To make sure your body can work correctly, even when it does many things at once,
Question 2= It helps your blood flow while you are eating it also helps digest and when in danger it also helps send signals to your brain.
Explanation:
The human body is made up of different structures; these are known as cells, which in turn group together to form tissues. Tissues come together to build organs, and organs make up systems (or apparatus).
The human body is organized in different levels of increasing complexity called levels of organization.
Living systems have chemical bases, but the quality of life itself arises at the cellular level. The interactions between the components of each level and the levels below it, allow the development of the next level of organization.
The levels range from subatomic particles to complex organisms, which in turn form communities that are related to each other by the flow of energy and matter. Each of the parts that make up human body allows it to fulfill a specific function.
The association between cells, as we have already seen, gives rise to tissues, which in turn will form organs. Therefore, they are vital for any human being to develop
In addition, very important metabolic reactions are carried out within cells, such as obtaining energy to be able to undertake vital processes. There are many types of cells that work in human beings, each one fulfills specific functions that mesh to give life.
Therefore, we can conclude that the levels of organization of the human body help it to fulfill vital processes, be more functional and increasing complexity.

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.

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.
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.

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.

A Change in Leaf Color
Leaves go to a lot of trouble to turn red in the fall.
By Emily Sohn
September 17, 2006 at 11:00 pm
Every autumn, traffic creeps along New England’s roads as visitors look everywhere but at the road. These tourists flock to the region as soon as leaves begin to change color from a summery green to spectacular shades of red, orange, yellow, and purple.
“Being in the Northeast during autumn is just about as good as it gets in this country,” says David Lee. He’s a botanist at Florida International University in Miami.
Lee studies leaf color, so he’s biased. But plenty of other people share his admiration. Areas of the United States with especially colorful fall displays attract thousands of leaf peepers.
Even as they “ooh” and “aah,” few people know what makes many plants blush in the autumn. Research has shown that leaves change color when their food-making processes shut off. The chemical chlorophyll, which gives leaves their green color, breaks down. This allows other leaf pigments—yellow and orange—to become visible.
No one knows exactly how global warming will alter forests and affect fall colors.
But “there’s still a lot we don’t know about this,” Lee says.
It isn’t clear, for example, why different species of plants turn different colors. Or why some trees become redder than others, even when they’re standing right next to each other. And no one knows exactly how global warming will alter forests and affect leaf-peeping season.
In summer, when a plant is green, its leaves contain the pigment chlorophyll, which absorbs all colors of sunlight except green. We see the reflected green light.
The plant uses the energy it absorbs from the sun to turn carbon dioxide and water into sugars (food) and oxygen (waste). The process is called photosynthesis.
When chlorophyll breaks down, yellow pigments in leaves become visible.
As days get shorter and colder in the autumn, chlorophyll molecules break down. Leaves quickly lose their green color. Some leaves begin to look yellow or orange because they still contain pigments called carotenoids. One such pigment, carotene, gives carrots their bright-orange color.
But red is special. This brilliant color appears only because the leaves of some plants, including maples, actually produce new pigments, called anthocyanins.
That’s a strange thing for a plant to do without a reason, says Bill Hoch of the University of Wisconsin in Madison. Why? Because it takes a lot of energy to make anthocyanins.
Answer:
No, they don't.
Explanation:
Trees need leaves for photosynthesis because leaves contain chlorophyll. As the article states, the food-making process stops after these trees lose their leaves. Some trees keep their leaves all year long.
According to the article, trees do not make their own energy every day. This is because the process of energy is accomplished by photosynthesis which is usually carried out by the leaves. But trees generally lost their leaves during a particular time of the year.
What process is used by plants to make energy?The process that is used by the plant in order to make energy is known as Photosynthesis. With the help of this process, all green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
There are some plants that hold leaves for the entire year. In these plants, energy is made every day. But in nature, these plants are very few. Plants carry out the process of photosynthesis when they need energy in the form of glucose which is also transferred into the storage form of energy in starch.
Therefore, trees do not make their own energy every day. This is because the process of energy is accomplished by photosynthesis which is usually carried out by the leaves.

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.
