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.

Javier decides to test which type of fertilizer works best on his begonias. He sets up flowers in 20 pots and divides them into groups of five. He waters three of the groups with three different brands of fertilizer and the last group with plain water. After 2 weeks, he measures how much each plant has grown.
What is the independent variable in this experiment?
What is the dependent variable in this experiment?
What is the control group in this experiment?
Answer:
The correct answer is :
The independent variable -types of fertilizers
The dependent variable - the growth of plants
The control group - plant gets water only
Explanation:
In any scientific experiment or study, the subject of the research gets a variable treatment that is manipulated or changed to check the different variable which shows the response to change made, variables that manipulated called as the independent variable. Types of different fertilizers are independent variable in this experiment.
The variable that shos response to a change in the independent variable called the dependent variable, the response in this study is the growth of the plants.
The control group in any study is the group that did not receive the treatment other groups receive, that is plants receive water only.
what tiny cell structure carries out a specific function within the cell
Answer:
Tiny cell structures, called organelles, carry out specific functions within the cell. Similar to the way your stomach, lungs, and heart have different functions in your body, each organelle has a different function within the cell.
These small cell structures are called organelles that perform specific functions within the cell. Just as the stomach, lungs, and heart have different functions in the body, each organelle has a different function within the cell.
What are Organelles?An organelle is defined as a subcellular structure that has one or more specific functions for the cell to perform, such as an organ in the body. The more important cell organelles are the nucleus, which stores genetic information; mitochondria, which generate chemical energy; and ribosomes, which assemble proteins.
It's the specific structure within a cell, and there are many different types of organelles also called vesicles within the cell and they actually have a function that's important, because we need to compartmentalize all the functions within the cell.
Thus, these small cell structures are called organelles that perform specific functions within the cell. Just as the stomach, lungs, and heart have different functions in the body, each organelle has a different function within the cell.

Choose all that explain why carbon is so important to life.
Carbon (C) appears in the second row of the periodic table and has four bonding electrons in its valence shell.
Carbon can form ionic bonds when combining with metals and covalent bonds with nonmetals.
Carbon can bond to itself in many different ways: chains, rings, branched chains.
Hydrocarbons contain only carbon, hydrogen, and oxygen.
Carbon can form single, double or triple covalent bonds.
Because carbon can bond in so many different ways, a single molecule can have different bonding configurations or isomers.

Of the nine gigatons of carbon released into the atmosphere by human activity how much is taken up by ocean sediments? how much is taken up by net terrestrial uptake? what is the surplus of carbon in the atom as a result of human activities per year?
The amount of carbon taken up by ocean sediments , terrestrial uptake and the surplus are;
- Ocean sediments; 30%
- Terrestrial uptake; 25%
- Surplus; 45%
The process described above in simple terms is basically the process of capturing and storing atmospheric carbon dioxide. This process is known as carbon sequestration. In carbon sequestration, the amount of carbon stored in reservoirs called oceanic sink is usually more than the amount in the atmosphere.Now, out of the carbon emitted to the atmosphere by human activities, it has been discovered that about 30% is taken up by the oceans, 25% is incorporated into terrestrial ecosystems and 45% remains in the atmosphere.Read more at; https://brainly.com/question/2463576

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.
