Re word this myth : a dead organism is the same as a nonliving thing in science

Answers

Answer:

Myth: A dead organism is the same as a nonliving thing in science.

Fact: A non-living thing can be very different than a living thing.

Explanation:Evidence: Once- living things are made up different things then non-living things. While a rock is a nonliving thing, it doesn't contain the same build as living things. If we were to look at a dead once living being, we could probably conclude that it was a living thing since it contains things like cells, proteins, etc. That other thing, like dirt, wouldn't have.

Which process takes CO2 out of the atmosphere

Answers

Answer:

Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen.

Explanation:

Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen. By respiration, O2 is removed from the atmosphere and replaced with CO2. However, these processes are not balanced. Some organic matter is not oxidized. (I'm very sorry if I'm wrong but I believe it's that)

The process that takes CO2 out of the atmosphere is Photosynthesis because photosynthesis removes all the CO2 from out the atmosphere and it is replacing the CO2 with O2. When we breathe we take O2 from the atmosphere and replaces it with CO2.

what property of water allows an animal to release excess heat in hot environments

Answers

Water is an excellent conductor of heat for which animals may control temperature through transpiration and thus maintain a suitable body temperature.

How does transpiration help animals to control body temperature?

The process of transpiration helps animals control body temperature by relating water which serves to conduct the heat and dissipate it into the surrounding environment to decrease the body temperature.

Therefore, with this data, we can see that transpiration helps animals control body temperature by increasing heat conductivity and thus removing the excess heat from the body.

The diagram above shows a right lateral view of a male testicle. Where would immature sperm cells be produced? (2 points)

A
B
C
D

Answers

Explanation:

D which is the seminiferous tubules is where sperms are produced

Immature sperm cells are produced in testes' seminiferous tubules through spermatogenesis before becoming mature sperm cells, the correct option is D.

Immature sperm cells, also known as spermatids, are produced in the seminiferous tubules within the testes. The testes are male reproductive organs located in the scrotum, below the pe-nis. The process of sperm production is called spermatogenesis, and it involves the division and differentiation of germ cells within the seminiferous tubules. Initially, spermatogonia (immature germ cells) undergo mitosis to form primary spermatocytes.

These primary spermatocytes then undergo meiosis to produce secondary spermatocytes, and finally, these secondary spermatocytes develop into spermatids. The spermatids will then undergo further maturation and structural changes to become mature sperm cells, which are eventually released into the male reproductive tract during ejaculation for potential fertilization, the correct option is D.

List one way in which manganese dioxide and catalase are different.

Answers

Manganese dioxide and catalase are different because manganese dioxide is an inorganic catalyst. Conversely, catalase is an organic enzyme.

What is an enzyme?

An enzyme is an organic catalyst (i.e., a protein) that acts to speed up a chemical reaction by lowering its activation energy.

Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide (H2O2) into oxygen (O2) and water (H2O).

Manganese dioxide also catalyzes the decomposition of H2O2 to oxygen and water, but it is an inorganic compound.

What happens to the carbon dioxide (CO2) levels of a plant when it does or does not have light?

Answers

Explanation:

Carbon dioxide is needed for photosynthesis, but oxygen is needed for cellular respiration. Assuming there is still oxygen then the plants will produce carbon dioxide and some of it will be reabsorbed by photosynthesis during daylight. However, ultimately there wouldn’t be enough carbon dioxide for the plants to grow and they will start to die. Some plants have evolved a C4C4 photosynthesis pathway so they only require a small amount of CO2CO2 to survive, however they do still require more than zero CO2CO2.

So basically you killed off all the plants and all the other non-microbial life died of starvation shortly afterward.
