Answer:
The cell organelles are the functional structures present inside the cell. Some of the organelles such as nucleus, mitochondria, chloroplast, Endoplasmic Reticulum, Golgi Complex etc are membrane-bound. Each organelle inside the cell has a different function to carry out. For example, the nucleus is the organelles which stores and protects the genetic material. Ribosomes are the organelles where a protein is formed. The Golgi- complex is the site where the proteins are modified and packaged.
Enzymes are a type of protein that aid in which of the following processes?
- cellular signaling and regulation
- transport across the cell membrane
- the breakdown of food molecules
- all of these
I think you forgot the answer choices. Is this your question?
If so, it is <u>D) all of these. </u>Enzymes aid in all kinds of microbiological processes, including cellular signalization, regulation and transportation - in addition to the breakdown of nutrients.
The correct answer is bacteria. Bacteria abundant in soil is the main source of its organic matter. This is because bacteria release energy in their systems which causes the soil to be more fertile and more capable of sustaining plant material. Without bacteria general processes of soil formation will not be possible.
It will be able to target specific cells that need to be killed such as pathogens and not kill the entire organism.
Answer:
B. The biomass of leaf litter in the bags will be greater in leaves with higher lignin content after the same length of time.
Explanation:
Lignin is a major, one of the most slowly decomposing components of dead vegetation, including leaf litters. The lignin content has been found to have a high correlation with litter decomposition.
<em>Hence, at the end of the experiment, the litter bag containing leaf litters with higher lignin contents will be expected to weigh more than those with lower lignin contents.</em>
The correct option is B.
