A mollusk is like a snail, slug or octopus. They have mantle and a radula.
Answer:
B) mitosis and cell differentiation.
Explanation:
Embryonic development of a multicellular organism has several stages.
In principle, cell multiplication occurs through the mitosis process in which each cell produces two identical daughter cells, in this phase the number of cells that make up the embryo is gradually increased.
The next phase corresponds to the cell differentiation in which by means of modifications in the gene expression, the cells acquire the morphology and the functions of a specific cell type and different from the rest of cell types of the organism
Answer: Option C
Explanation:
The process of photosynthesis can be defined as the process by which the plants and blue green algae make food by the use of water and carbon dioxide are used in the presence of sunlight to get converted into glucose.
The leaves of the plant is the main site for this process and the conversion of light energy into chemical energy takes place here only.
Carbon dioxide that is used in this process is removed from atmosphere which is a greenhouse gas.
Answer:
This question is asking to fill the blank spaces. The answers are:
1. Capsid
2. Cell content
Explanation:
A virus is an organism that is incapable of reproducing itself without invading an host cell. It is generally made up of a genetic material (DNA or RNA), and a protein coat called capsid. This CAPSID is the part of the virus that protects its genetic material and content.
This function of capsids is similar to that of the cell membrane in prokaryotic and eukaryotic cells as they both function to protect the cellular content including the genetic material.
