Answer:

The law of conservation of mass

Explanation:

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

If convection cells in the asthenosphere are the mechanism behind plate tectonic movement, what powers the convection cells?

a) energy from the sun
b) energy from the earth's core
c) air pressure changes
d) energy from magma

Answers

I think the answer will be C

The energy that powers the convection cells is ENERGY from the earth's core (Option B).

Convection currents, also known as convection cells, are caused by density differences within a body of liquid or gas.

Convection cells inside of the Earth form as material near the Earth's core heats up.

The asthenosphere refers to the upper mantle layer beneath the lithospheric mantle which is involved in plate tectonic movement.

The heat inside the Earth's core heats the asthenosphere, which is associated with the movement or 'motion' of convection cells.

In conclusion, the energy that powers the convection cells is ENERGY from the earth's core (Option B is correct).

Explanation:

Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.

As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.

Answer:

1. For generating healthy cells to form replacement organs like brains

Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.

What is stem cell?

Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.

Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.

Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.

This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.

Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.

Thus, the correct option is 4.

A. Bacteria are prokaryotes and protists are eukaryotes

B. Bacteria have a cell membrane while protists do not

C. Bacteria have ribosomes while protists do not

D: bacteria have cytoplasm while protists do not

Answers

Answer:

The correct option is A. Bacteria are prokaryotes and protists are eukaryotes

Explanation:

The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.

The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.

Therefore the answer that best explains the difference between both protists and bacteria

Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.
