Answer:
plant helps ant and ant helps elephant
Explanation:
The plant provides shelter and food for the ants and it seems that the ants protect the plants from elephants
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
Nonrenewable resources are used commonly and are quickly running out, and it takes longer for us to form more of these.
Answer:
The question is incomplete.
However, I notice that your question is mainly dealing with
"Nucleotides with a single ring structure"
I tackled that part, also providing explanation to the point you focused on.
Explanation:
Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.
Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.
Answer:
3) The correct answer would be the third option.
Enzymes are biocatalysts which increases the rate of a biochemical reaction is decreasing the activation energy required by the reaction.
The substrate binds to the active site of the enzyme to form an enzyme-substrate complex. It is then converted to enzyme-product complex. Lastly, the product is released and the enzyme is ready for a new cycle of reaction.
4) The correct answer would be cohesion.
Cohesion or cohesive force refers to the attractive force by which like-molecules are stick together.
For example, water molecules are stick together to form droplets.
