Answer:

b.It increases the likelihood that daughter cells contain different genetic material.

Explanation:

Morgan and Cattell for the first time used the term ‘crossing over’.  Crossing over takes place during prophase I of meiosis. During crossing over, chromosome segments of non-sister chromatids of homologous chromosomes get exchanged. As a result, the daughter cells acquire different genetic materials. Thus, it provides genetic variation by creating a new combination of genes or get recombination and produces hybrids.

Is facilitated diffusion an example of active transport
Maru [420]
Fascilitated diffusion is an example of passive transport because a protein carrier helps pass a substance through the cell membrane. No energy is required to do this, which is why it is passive. (Active transport involves the expenditure of energy).

Which of the following is an organism whose cells each contain a membrane<br> bound nucleus?
DerKrebs [107]

Answer:

D. Eukaryote

Explanation:

An organism that has membrane-bound organelles will have more complex organelles like mitochondria, Golgi apparatus, and ER. These are known as Eukaryotes. Additionally, they will have a nucleus that has the DNA coiled inside. Prokaryotes do not have membrane-bound organelle and the DNA floats in the cytoplasm. Most plants and animals are eukaryotes and all multicellular organisms are too.
