Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
<u>If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes</u> and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.

Answer:
A. Both are unicellular organisms that lack a membrane-bound nucleus.
Explanation:
Bacteria and archaea are both prokaryotes. Prokaryotes are always single celled organisms. They also do not have a defined-nucleus. These features differentiate them from eukaryotes, which all have a membrane-bound nucleus. Some eukaryotes are also multicellular (but not all)
The go through technology and have to change with it vc if u keep it with the same u will never change
Answer:
- transport nutrients into the cell that cannot otherwise cross the phospholipid bilayer
- transport wastes out of the cell that cannot otherwise cross the cell membrane
Explanation:
Cell membrane integral proteins especially trans-membrane proteins facilitate and regulate the movement of particular molecules across the cell membrane. Examples of these molecules are glucose and sodium ions. These molecules are either charged and cannot pass through the hydrophobic lipid layer of the cell membrane and/or are too large to pass through the cell membrane pores (like the aquaporins).Other types of cell membrane proteins are peripheral proteins. Collectively these proteins can have several other functions include cell signaling, enzymatic activity, cell-to-cell recognition , and etcetera.
