Sodium would lose an electron to become a positively charged ion.
The given question is not about true/false. The correct question is:
Question: Sheath of schwann cell containing cytoplasm and nucleus that encloses myelin.......
Answer:
Neurolemma
Explanation:
Schwann cells are one of the two types of neuroglia that produce myelin sheaths. Schwann cells produce the myelin sheath in the peripheral nervous system. These cells produce the myelin sheaths around axons during fetal development. During the process, several layers of the glial plasma membrane surround the axon. The Schwann cell’s cytoplasm and nucleus form the outermost layer. On the other hand, the inner part is composed of multiple layers of Schwann cell membrane and is called the myelin sheath. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called the neurolemma.
Answer: d. an algae that grows on the surfaces of rocks.
Kelps are large brown algae seaweeds that grow along rocky shorelines so we choose d as an answer. Three types of Kelps are found mostly on<span> the Pacific coast, Macrocystis (giant </span>kelp), nereocystis luetkeana) and the Alaria fistulosa.
Kelps which are about 30 different genera, included species from Laminariales and Fucales.
Answer:
mold
Explanation:
Alexander Fleming was a Scottish physician and scientist. He was known for the development of penicillin.
Alexander Fleming discovered a type of <u>mold</u> that kills bacteria, which led to the development of Penicillin.
The mold created around itself a bacteria-free circle.
Fleming experimented further and named the active substance penicillin.
Answer:
plant growth rate will remain the same
Explanation:
Photosynthesis is the process by which green plants generate carbohydrates (sugars) and oxygen from carbon dioxide, water, and light energy.
The balanced equation is as follows: 6CO2 + 6H20 + (solar energy) → C6H12O6 + 6O2
Note that "all other factors affecting photosynthetic rates were equal, ONLY atmospheric CO2 concentration were the main factor affecting photo synthetic rates"; then time (400, 000years) and 30 degrees C in the daytime temperature of 30°c will mean nothing.
Plants' chlorophyll will only trap the solar energy required to combine 6 moles of CO2 to 6 moles of H2O. Hence,
