Foraminifera (Foram) are members of a phylum or class of amoeboid protists characterized by streaming granular ectoplasm for catching food and other uses; and commonly an external shell of diverse forms and materials. Tests of chitin are believed to be the most primitive type.
Foraminifera are found in all marine environments, from the intertidal to the deepest ocean trenches, and from the tropics to the poles, but species of foraminifera can be very particular about the environmentin which they live.

ice forming in cracks of rocks
b.
acid rain falling on sidewalks
c.
waves washing over rocks on the beach
d.
water washing away soil in an area used by off-road vehicles
Answer;
C. waves washing over rocks on the beach
Explanation;
-Erosion is a natural process that forms part of the lifecycle of sites, resulting from the action of wind or water. It is a geological process in which earthen materials are worn away and transported by natural forces such as wind or water.
-Example of erosion; Wind carries small pieces of rock awayfrom the side of a mountain, waves washing over rocks on the beach, etc.
The transfer of genes from one population to another is called gene flow . Gene flow can occur through a variety of mechanisms, including:
Migration: When individuals move from one population to another, they bring their genes with them.
Interbreeding When individuals from different populations mate, their offspring inherit genes from both parents.
Horizontal gene transfer This is a process by which bacteria can exchange genes with each other, even if they are not closely related.
Gene flow is an important factor in evolution, as it can introduce new genes into a population and increase genetic diversity. This can help the population to adapt to new environmental conditions and to resist diseases.
Here are some examples of gene flow:
Monarch butterflies Monarch butterflies migrate from North America to Mexico each year. When they mate in Mexico, their offspring inherit genes from both parents. This gene flow helps to maintain the genetic diversity of the monarch population.
Gene flow is a complex phenomenon that can be affected by a variety of factors, including the distance between populations, the rate of migration, and the presence of barriers to migration.
