Answer:
Only cells contain cytoplasm
Explanation:
Viruses are microscopic creatures (not alive though), that can use genetic material such as RNA or DNA, just like cells.
About protective covering, viruses use a capsule to protect this genetic materials, while cells use the cell membrane and the cell wall (like plants and some bacteria).
Answer:
Ribosomal RNA (rRNA), molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein.
Explanation:
The given question is incomplete, the complete question is:
Grizzly bears are an integral part of the ecosystems in which they live and thrive. An example of their value to biodiversity includes their role in providing forests with a large amount of nitrogen needed to grow and persist through the consumption of salmon. This is an example of what type of species value?
Select one:
a. None of the above
b. Direct
c. Indirect
d. Cultural
Answer:
The correct answer is indirect value.
Explanation:
An illustration of the environmental service value is the production of a huge concentration of nitrogen within a locality. All the non-consumable values like economic values, social, cultural, aesthetic values, etc. come under the category of indirect values.
An indirect value indirectly helps an organism to thrive within a surrounding, like in the given case production of nitrogen is a non-consumable value, thus, it can also be considered as an indirect value. On the other hand, all the productive and consumable values in the form of medicine, food, etc come under the category of direct value.
The question that cannot be tested is Are people who drink tea happier than people who don’t drink tea?
This is not a good scientific question because it is hard to investigate happiness of someone.
Good scientific question needs to:
• Be estable-through measurements or experiments
• Provide an answer
• Lead to hypothesis.
The advantage to a scientist is that it makes calculations easy using exponential functions. The disadvantage is that it may not capture some subtle complication that changes the answer at the fifth place after the decimal point.<span>
