arrow with the type of energy being transferred.
chemical

Answers
Answer/Explanation:
=> The first arrow linking the sun and the plants represents transfer of RADIANT energy. The sun through its sunlight radiation provides energy for autotrophs such as plants to manufacture their food.
=> The second arrow from plants to rodent represents transfer of CHEMICAL energy. The chemical energy that is manufactured and stored between the molecules of the plant as food, is transferred to rodents as primary consumers.
=> Third and fourth arrow from the rodent to owl, and from the rodent to the wolf both represents CHEMICAL energy transfer.
=> Fifth arrow from the wolf to the surroundings show heat loss during metabolic processes in the wolf's body which represents THERMAL energy transfer from the wolf to the environment.
=> The width arrow from the wolf to decomposers also show THERMAL energy transfer as the wolf dies and decay, Hera is released.
The arrows represent the transfer of energy which are described as follows:
1. Radiant energy
2. Chemical energy
3. Chemical energy
4. Chemical energy
5. Thermal energy
Radiant energy is transferred through the first arrow connecting the sun and the plants. Sunlight gives autotrophic organisms like plants the energy they need to produce food. The transfer of chemical energy from plants to rodents is shown by the second arrow. Rodents are the main consumers of chemical energy that is produced and stored as food between plant molecules.
The third and fourth arrows, from rodent to owl and from rodent to wolf, respectively, both indicate the transmission of chemical energy. The fifth arrow shows heat loss from the wolf's body during metabolic activities, indicating thermal energy transfer from the wolf to the surrounding environment.

Considering the theory of continental drift, is it possible that the continents of the earth could once again become one? Explain your answer.
Answers
Answer: The Earth's continents are in constant motion. On at least three occasions, they have all collided to form one giant continent. If history is a guide, the current continents will coalesce once again to form another supercontinent. And a study in Nature now shows how that could come about.
You can think of continents as giant puzzle pieces shuffling around the Earth. When they drift apart, mighty oceans form. When they come together, oceans disappear. And it's all because continents sit on moving plates of the Earth's crust.
Then, Now And Future
A new model of continental drift predicts that the next supercontinent could form near the North Pole — in another 100 million years or so.
Two of the previous supercontinents, which formed 200 million years ago (Pangaea) and 800 million years ago (Rodinia).
Mitchell, et. al./Nature
The Americas and Asia may fuse together to form a new supercontinent, "Amasia."
Mitchell, et. al./Nature
"Continents on these plates typically move, I would say, at the rate your fingernails grow," says Ross Mitchell, a graduate student at Yale University. That may seem slow, but it adds up over hundreds of millions of years.
Look at an atlas and you can imagine how Africa and South America, for example, once nestled together.
"Rewind the tape and bring all the continents back into their jigsaw arrangement, you have this vast landmass of all the Earth's continental blocks together," Mitchell says.
Last time all the landmass clumped up, it formed a supercontinent called Pangaea. The dinosaurs walked there. But Pangaea wasn't the first.
"There had been three, possibly a debated fourth supercontinent through the billions of years," Mitchell says.
He has been studying that deep history by looking at tiny magnets buried in rock around the world. Those magnets pointed north when they were locked into the rock. Sample those magnets in layers of rock laid down over millions of years, and you can tell the story of how those continents have moved.
And naturally, that led Mitchell to wonder what the next supercontinent will look like.
There have been two leading ideas. One is that the continents will collapse together again at the site of the last supercontinent, centered on Africa. That would squeeze the Atlantic Ocean shut. The other idea is that the Atlantic would keep growing and growing.
Considering the theory of continental drift, is it possible that the continents of the earth could once again become one.
The Earth's continents are constant motion, they will collide to form a giant continent and the current continents will coalesce once again to form another supercontinent.
What Is Continental Drift Theory?Continental drift theory was the revolutionary theory developed by Alfred Wegener (1880-1930), a German meteorologist, climatologist, and geophysicist.
He put forwarded his hypothesis that the continents included in a large enormous landmass or supercontinent about 240 million years ago before breaking and drifting.
This supercontinent was named as Pangaea.
Some major drawbacks of this theory are he did not explain why the drift happened during Mesozoic era, but not in earlier era.
He did not take oceans into account for his hypothesis, proofs are based on generalized assumption, so it is not significant.

Why is the phloem in a leaf important to the roots of a plant?
A. It transports oxygen to the roots of the plant.
O B. It transports blastocysts to the roots of the plant.
O C. It transports water from the roots to the leaves.
OD. It transports carbohydrates to the roots.
Answers
Answer:
D. It transports carbohydrates to the roots.
Explanation:
Phloem is mainly used to transport nutrients from their region of production to the region that needs or stores the nutrient.
In photosynthesis, the method that plants make food, starch is produced. As the root hair cells needed energy to function, nutrients is needed so that it can respire and produce energy.
Therefore, when starch is produced, they will travel down the plants by the phloem to the roots where the nutrients is used.
brainlest please
As it delivers carbohydrates to the roots, the phloem in a leaf is vital to a plant's roots. So, the correct option is D.
What is Phloem?The plant tissue known as phloem is in charge of moving sugars, nutrients, and other organic substances from the leaves, where they are made by photosynthesis, to the other sections of the plant, such as the roots, flowers, and fruits.
Phloem has a bidirectional transport system that enables it to carry materials both across and down the plant. Sieve-tube elements and companion cells, which make up phloem tissue, are specialised cells.
A vascular tissue called phloem is in charge of moving sugars (carbohydrates) from the leaves to the roots and other sections of the plant. The plant may transfer the byproducts of photosynthesis through its whole system thanks to a process called as translocation.
Therefore, the correct option is D.

For both conditions, explain how protein synthesis contributes to the symptoms of the disease
Answers
Answer:
Explanation:
Among the causes of protein synthesis disorders, an important place is occupied by various types of alimentary insufficiency (complete or incomplete starvation, lack of essential amino acids in food, violation of a certain quantitative ratio between essential amino acids entering the body).
The protein synthesis correspondingly contributes to the symptoms of the disease by the fact that it produces some dysfunctional or bizarre proteins which significantly stimulate the specific types of disorder in organisms.
What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make protein in order to perform specific functions within the body of living organisms. It occurs in two stages, i.e. transcription and translation.
Transcription is the stage of protein synthesis through which the effective transfer of genetic instructions in DNA to mRNA in the nucleus takes place. While the process of translation involves the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). It occurs in the cytoplasm of the cell.
The disorder of protein synthesis is occupied by numerous kinds of alimentary insufficiency such as entire or incomplete starvation, insufficiency of mandatory amino acids in food, and violation of essential amino acids entering the body.
