What are some similarities and differences between landslides and creeps? Thank you!
dimulka [17.4K]

Answer:

A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.

8. Crossing over is an exchange of corresponding segments between nonsister
prisoha [69]

The main benefit of crossing over is that it increases genetic diversity.

<h2>Crossing over and Genetic Diversity</h2>

Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells.

The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.

Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment.

In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.

The main function of the rough endoplasmic reticulum is the production of Q
9966 [12]

Answer:

4. Membrane and proteins secreted by the cell

Explanation:

Endoplasmic reticulum (ER) is one of the organelle that makes up the endomembrane system of eukaryotes. The ER is of two types viz: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).

The RER is called "rough" because of the ribosome organelles that are attached to its surface. The attachment of this ribosomes (site of protein synthesis) also defines its function. The RER is principally involved in the production of protein. Hence, the Rough Endoplasmic Reticulum functions mainly in the production of membrane and proteins secreted by the cell.
