The answer you are looking for is chitin.


According to a page that I found with info on the subject,

"All arthropods have bodies divided into segments and covered with a hard EXOSKELETON. This tough casing is made of a protein called chitin, which is also found in human fingernails."

andrew11 [14]

Answer:

C) They are usually transmembrane

Explanation:

Integral membrane proteins (intrinsic protein) are known to be a type of membrane protein that is attached permanently to the biological membrane. Also, they are made up of significant proteins that are encoded in the genome of the organism. Furthermore, trans-membrane proteins allow the transportation of specific substances across the membrane and they undergo significant changes in order to move substances across or through the membrane.

Sexual reproduction in eukaryotes increases genetic variation. In prokaryotes, transformation, transduction, and conjugation are
stealth61 [152]

Answer:

A

Explanation:

All living organisms pass on or transfer their genetic material to their offsprings. However, this transfer of genes occurs through the process of reproduction (sexual or asexual). Reproduction may (in case of sexual) or may not (in case of asexual) ensure genetic variation among species.

Eukaryotes that undergo sexual reproduction increase genetic variation among their species by undergoing Crossing-over (exchange of chromosomal segment between non-sister chromatids of homologous chromosomes) during meiosis or gamete formation. This process of transferring genetic material directly from parents to offsprings is called VERTICAL GENE TRANSFER, and only sexual-reproducing eukaryotes ensure genetic variation through this process.

On the other hand, prokaryotic organisms cannot undergo sexual reproduction, they undergo asexual reproduction instead and asexual reproduction does not guarantee genetic variation since identical daughter cells as the parents are produced from the process. However, to promote genetic variation among their species, they employ the processes of transformation, transduction and conjugation which are all forms of HORIZONTAL GENE TRANSFER because it involves transfer of genetic material from one cell (donor) to another (recipient) which do not have the parent-offspring relationship.
