Biological macromolecules are synthesized by dehydration
synthesis reactions and are broken down by hydrolysis
reactions.
<h3>What are Biological macromolecules?</h3>
These are formed from smaller compounds and are necessary
for proper life functions of cells. Examples of these
macromolecules include:
Dehydration synthesis involves the loss of water molecules in
the process while hydrolysis reaction involves the addition of
water molecules.

Answer:
A carrier is an individual who carries and is capable of passing on a genetic. Carriers are associated with diseases inherited as recessive traits. An individual having one normal allele and one mutated allele does not have the disease.

Most of them contain a pair of jaws and eversible pharynx to grab the food in their mouth quickly. Jaws are used to biting food and grasping prey. Filter feeders contain a ciliated crown of palps to filter food going into the mouth.
<u>Answer</u>: Appear to function in similar ways across diverse groups of organisms.
<u>Explanation</u>:
- The <em>hox</em> genes are a subset of homeotic genes.
- The function of the hox genes is to control the development of the body plan of an individual during the embryonic stage.
- Thus, the basic body form of an organism is laid down with the help of these genes.
- <em>These genes are present in many different species from fruit fly to mice to humans</em>.
- The reason that they are present in different organisms is that there was a common ancestor that possessed the hox gene cluster and then the genes were passed on to different vertebrates. However, the slight changes that have occurred in these genes are due to duplication events.
