Which activity uses ATP to raise body temperature?

shivering

storing fats

panting

hibernating

Answers

Answer:

shivering it creates energy, 60% of which is wasted on heat

Shivering uses ATP to raise body temperature. So the correct option is A.

What is shivering?

Without your conscious involvement, your body controls how it reacts to stress, illness, heat, cold, and other situations. When you are too hot, for instance, you sweat to cool the body, but you don't have to think about it. And you shiver naturally when you're chilly.

Your muscles quickly contract and release, which results in a shudder. Your body naturally tries to warm up as it becomes cooler, which is why you are experiencing this uncontrollable muscular activity.

The only reason you shiver, though, is in response to the cold. You may tremble and shiver due to a variety of factors, including illness. You could start to shiver as the temperature falls below what your body considers comfortable. Your body's surface heat production might increase by around 500% when you can see yourself shivering. However, shivering will only temporarily warm you up.

Your muscles will eventually run out of glucose (sugar) to use as fuel and become too exhausted to contract and relax after a few hours. The temperature during which shivering begins varies depending on the individual. Children, for instance, may shiver more readily in reaction to higher temperatures than an adult with greater body fat would.

Therefore the correct option is A.

Transcription copies DNA into RNA. Messenger RNA is transcribed DNA that encodes proteins. Therefore, a new mRNA strand is synthesized here and the process is transcription.

What is transcription?

The act of producing a copy of the genetic information that is contained in a strand of DNA and converting it into a complementary strand of RNA (also known as messenger RNA or mRNA) with the assistance of RNA polymerases is referred to as transcription. This process is carried out in the cytoplasm of prokaryotic cells. This process takes place within the nucleus of eukaryotic cells.

There are three stages that make up the process of transcription: initiation, elongation, and termination.

First Step. RNA polymerase is responsible for opening up the DNA double helix (initiation)The Following Step RNA The nucleotides in the DNA template strand are the starting point for the formation of nucleotides (Elongation)The final step The newly produced mRNA is then exported from the nucleus (termination)

Answers

Answer:it’s D

Explanation:

Because plants take carbon dioxide

The statement that is best illustrated by the diagram is that plants can take in carbon dioxide from air or water. The correct option is D.

What is the carbon cycle?

The carbon cycle refers to the biogeochemical processes that keep the earth's and the atmosphere's carbon levels stable and in balance.

The pathways show how the carbon compound is used in various processes and sources while maintaining its natural composition. The cycle's primary goal is to maintain a balance of carbon in the ecosystem's biotic and abiotic components.

Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.

Therefore, the correct option is D, plant can take in carbon dioxide from air or water.

The statement "the properties of a substance are not affected by chemical reactions" is false.

What are physical and chemical properties?

A substance's physical property is a quality that can be seen or quantified without affecting the substance's identity. Color, density, hardness, and melting and boiling points are examples of physical qualities.

A quality of matter that is unrelated to a change in its chemical makeup is called a physical property. Density, color, hardness, melting and boiling points and electrical conductivity are a few common examples of physical qualities.

Chemical changes result in new compounds with different properties from the original ones, as well as new particles and maybe altered particle numbers.

D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

Answers

Answer:

D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

Explanation:

Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.

Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.

Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.

Generally, adhesion or adhesive forces is a term used to describe the force of attraction between molecules of different substances. This is as opposed to cohesion or cohesive forces which refers to the force of attraction between the molecules of the same substance.

Hence, when molecules of water attract or stick to other molecules, the force at play is an adhesive force or simply adhesion.

Convert solar energy to chemical energy stored in sugar

Explanation:

Photosynthesis is the process whereby green plants manufacture their food, which is in the form of a sugar (glucose). The photosynthetic process, generally, combines carbon dioxide (CO2) and water (H2O) in the presence of sunlight, which provides energy used.

The sugar (glucose) produced stores chemical energy in its chemical bonds. In a nutshell, photosynthesis converts SOLAR ENERGY (from sun) into CHEMICAL ENERGY (in glucose), which is the purpose of the process for organisms that undergo it.
