Answer:
C. A prokaryote
Explanation:
A prokaryote is an organism that consists of a single cell that does not have a nucleus or membrane-bound organelles.
Each "human body cell" has 46 chromosomes. But human sex cells have 23 unpaired chromosomes in each cell. Sex cells are created by a special type of cell division, Meiosis.
Answer:
When occurs in gametes
Explanation:
Mutations are changes in DNA sequence that can create genetic variation within the population and thus are the ultimate source of new alleles . Mutations can occur as a result of mistake during the DNA replication, under the influence of environmental factors (UV radiation, chemical agents). They can be harmful, beneficial, neutral. Based on the location of cell mutation, they can be divided into:
- somatic mutation-within the somatic cells, these mutations affect only the parents (not inherited)
- germline mutation-within gametes, can be inherited on offspring.
Weather can differ and change with climate and can almost change suddenly. Erosion is wear from the surface or areas over time.
Answer:
Genetic information is bundled into packages of <u>DNA</u> known as <u>chromosomes.</u>
Explanation:
DNA is the genetic material. It's how we pass down traits to our offspring. It's the cell's instructions for how to build.
Chromosomes are the, well, packages of DNA. They become visible in meiosis. They basically look like little Xs. Humans normally have 23 of these bundles that determine who we are.
