Living cells are classed as either prokaryotic or eukaryotic. Which of the following characteristic(s) identify both cell types,
Alex

Answer:

have a nucleus - Eukaryotic

contain cytoplasm - Both

comprise most multi-celled organisms - Eukaryotic

mostly single-celled organisms - Prokaryotic

have membrane-bound organelles - Eukaryotic

are the smallest unit of living matter - Both

are produced by division of another cell - Both

contain DNA - Both

Explanation:

1. Eukaryotic cells are cells that possess a membrane-bound nucleus that houses their genetic material.

2. Both eukaryotic and prokaryotic cells have a cytoplasm, which is the gelatinous substance where all other organelles and substances are found.

3. Most multicellular organisms comprises of eukaryotic cells.

4. On the other hand, most single celled organism, are Prokaryotic.

5. Eukaryotic cells, in addition to the possession of a membrane-bound nucleus, they also possess membrane-bound organelles e.g mitochondria, endoplasm reticulum.

6. Cells, generally, are the smallest unit of living matter. This comprises of both eukaryotic and prokaryotic cells.

7. Likewise, all cells arose from already preexisting cells according to the cell theory. Therefore, both eukaryotic and prokaryotic cells are made by the division of another cell.

8. Both prokaryotic and eukaryotic cells have a genetic material like DNA where they store genetic information.

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some
mihalych1998 [28]

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
