I think clumping is caused by the mixture of antigen and the corresponding antibody. Agglutination( clumping) is the process that occurs when an antigen is mixed with its corresponding antibody. This is commonly used in blood grouping. An example is the clumping of red blood cells in the presence of an antibody or complement. In blood transfusion Clumping indicates that the blood has reacted with a certain antibody and is therefore not compatible with blood containing that kind of antibody.

Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. 4
Rasek [7]

Natural selection would probably favor different varieties in the different islands. In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti (due to lack of food resources). Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.

In a soft-bottomed intertidal community, oxygen would be most plentiful for meiofauna in which type of bottom?
Sonbull [250]

Answer:

The options are:

A. Gravel

B. Sand

C. Silt

D. Clay

E. Mud

The answer is A. Gravel

Explanation:

Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.

Gravel aren’t tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
