Which structural component is found in DNA but not in RNA?
O ribose
O deoxyribose
O phosphate group
O nitrogenous base

Answers

Answer 1

Answer:

Deoxyribose

Explanation:

Neither deoxyrinose nor thymine is found in RNA.

Answer 2

The structural component found in DNA but not in RNA is deoxyribose.

What is DNA and RNA?

Both DNA and RNA contain the same nitrogenous bases (adenine, guanine, cytosine, and uracil in RNA or thymine in DNA) and phosphate groups.

However, DNA contains deoxyribose sugar in its backbone, while RNA contains ribose sugar. The difference between the two sugars is that deoxyribose lacks an oxygen atom on the second carbon in the sugar ring, whereas ribose has an oxygen atom at that position. This difference in sugar composition is responsible for some of the unique properties of DNA, including its double-stranded helical structure and greater stability compared to RNA.

Sophie says dolphins and sharks look very similar, so they must be related. Jake disagrees, saying DNA evidence has shown that dolphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos. Who is correct using the modern system of classification?
Sophie is correct because dolphins look more like sharks than like hippos.
Jake is correct because classification is based on evolutionary relationships.
Both are correct because traditional and modern classifications can overlap.
Neither is correct because neither is taking into account both the traditional and modern systems

Answers

According to the modern system of classification, Jake is correct because classification is based on evolutionary relationships. So, the correct option is B.

What do you mean by the modern system of Classification?

The modern system of classification was invented in order to identify the evolutionary relationships between the organisms that could be more accurately depicted.

Shark belongs to the group of fishes, while dolphin belongs to the group of mammals. They are more or less looking very close to each other. But the modern system of classification reveals the differences between the. And DNA evidence has shown that dolphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos.

Describe the four major spheres that support life on Earth.
Explain how rays AB and AC form both a line and an angle.

Answers

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Two rays AB and AC having the same endpoint are opposite rays if they two rays are unequal but line AB is equal to line AC. Otherwise they are nonopposite. An angle is the union to two nonopposite rays AB and AC sharing the same endpoint. The angle is denoted by either angle BAC or angle CAB.

When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in complexity? cell organism organ system tissue

Answers

Answer:

Tissue.

Explanation:

Cells work together to make tissues and tissues work together to make organs. I believe tissues are right under organs in terms of complexity.

The level of organization is defined by the simple to complex arrangement. The tissues are below the organs in the level of complexity. Thus, option d is correct.

What is the level of organization?

The arrangement of the most simple to the complex structure in a hierarchical manner is called the level of organization. It makes the population and the community of the ecosystem.

The atom is the most simple level that aggregates to form a molecule that makes a cell. Cells with similar functions make the tissues. The tissues with various fucntions combine to form an organ.

An organ along with different organs makes an organ system. The various organ system with various roles and activities makes the organism. Many organisms make a population that results in a community, ecosystem, and biosphere.

Which of the following molecules supplies the main source of short-term energy used in cellular
respiration?
F) Enzymes
G) Carbohydrates
H) Lipids
J) Proteins

Answers

Answer:

g

Explanation:

its g because thats right may i have brainlyist i need it to upgrade

The molecules supply the main source of short-term energy used in cellular respiration is - G) carbohydrates.

All living organisms carry out cellular respiration in order to get energy for cellular processes. All biomolecules proteins, lipids, and carbohydrates provide energy by breaking down during this process. however, sugar molecules or carbohydrates are used to provide short-term and immediate energy in the form of ATP by cellular respiration.

Proteins -

During extreme starvation when all carbohydrates and fats in the body are used up.The respiratory quotient (RQ) of proteins - 0.83–0.9.

Carbohydrates-

The major respiratory substrate is in form of glucose or carbohydrates in cells.The respiratory quotient (RQ) of carbohydrates - 1.

Fats-

used only if carbohydrates are in short supply. It yields almost twice as much energy as carbohydrates generally do not use.The respiratory quotient (RQ) - 0.71

Thus, carbohydrates like glucose and sucrose are probably the two most common organic molecules that organisms require to produce short-term energy from cellular respiration.

It’s important there’s molecules that could do so for keeping homeostasis, food movement, keeping the cell isotonic with movement of water, glucose to go into cell to not let it starve and waste to escape and not build up in cell

What is importance of a molecule to move across the cell?

Biology places a great deal of importance on the passage of substances into and out of cells (for example, nutrients into and poisons out), as without it, no cell and hence no organism could survive for very long.

Moving chemicals throughout the body is essential for living cells. Transporting chemicals into and out of cells is necessary.

Examples include oxygen, carbon dioxide, and dissolved food. Active transport, osmosis, and diffusion are used to accomplish this.

Therefore, transport of a molecule into and out  of cell is important to functioning of cell.
