Each chromosome (replicated or not) contains 2 chromatids.
Cell Wall
Explanation:
About 63% of the bacteria tested were Gram-negative, which means that they have a cell wall that is more resistant to certain classes of antibiotics than the cell walls of Gram-positive bacteria.
Answer:
eukaryotic
Explanation:
Fungi (or Mushrooms) are eukaryotic and have a complex cellular organization.
Algae are eukaryotic cells, or cells that contain a nucleus, which makes them slightly more complex than bacteria
Protozoa are single-celled eukaryotic (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy.
Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.
