Answer: Meiosis is a process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. Meiosis usually involves two distinct divisions, called meiosis I and meiosis II. By the end of meiosis II, the diploid cell becomes four haploid cells.
Explanation:
The correct answer is Protozoa, plant and fungi.
The kingdom Protista consits of several organism that includes Protozoa, plants and fungi. Protists are the first eukaryotes that came on earth, it includes multicellular organisms and unicellular organisms as well.
- It includes plant like protists called as autotrophs.
Example: Red, brown and green algae.
- It also includes fungi like protists called as decomposers.
example: slime molds and water molds.
- It also includes protozoans like Zooflagellates and cilliates.
Answer:
The volume of solution B will increase
Explanation:
In a non-penetrating solute, there is denial of a solute to cross the cell membrane.This implies that the solute will not be able to cross the cell membrane. So if the biological membrane is serving as a partition between a solution A containing 400 mosmol/L non-penetrating solute and a solution B containing 600 mosmol/L non-penetrating solute, The volume of solution B will increase.
If the inner lining of the air sacs neither thin nor highly vascularized, then it can be inferred that AIR SACS ARE CANNOT BE THE SITES OF GASEOUS EXCHANGE BETWEEN AIR AND BLOOD. Air sacs are generally lined with mucus and surrounded with blood capillaries.
In case of birds, air sacs play an important role in respiratory system.
