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
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).

Which answer best explains the difference between protists and bacteria?
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.

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.
