Answer:
In an aquatic ecosystem, the plants are present both on the subsurface and bottom bed rock of the aquatic body. These are the producers of the ecosystem because they provide food to the living organism in the lake. In day plants growing on the surface of the water takes up carbon dioxide from the atmosphere which is being absorbed in the water, to conduct the process of photosynthesis. These plants release oxygen, which supports the life of aquatic animals. In this way plants limit the abundance of carbon dioxide in water. But in night plants undergo a process of respiration, which releases carbon dioxide. The abundance of carbon dioxide increases in night along with the carbon dioxide being absorbed from the atmosphere. Therefore, concentration of carbon dioxide increases considerably in night as compared to day.
Answer:
true or so google says lol
B. Prokaryotic
C. Nucleus
Prokaryotic cell don't have any membrane bound organelles but they do have a nucleus. Thus, the correct option is B.
Prokaryotic cells are defined as the cell which single-celled, non bound organelle microorganisms known to be the earliest on earth. Prokaryotes comprises bacteria and archaea.
The photosynthetic prokaryotes comprises cyanobacteria that perform photosynthesis. A prokaryotic cell comprises of a single membrane and hence, all the reactions occur within the cytoplasm. The below diagram shows a prokaryotic cell.

Dna
Explanation:
The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus
Answer:
During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.
Both Meiosis 1 and 2 have the same phases: Prophase, Metaphase, Anaphase and Telophase. One difference is that Meiosis 1 starts with a diploid cell and Meiosis 2 starts with 2 haploid cells, each with a homologous pair. ... Since there are no homologous pairs (only chromatids), recombination can not occur
