Answer:
Plants have a cell wall
Explanation:
GMO modification is different for plants and animals <u>because plant cells have cell walls, unlike animal cells. </u>
<em>GMO refers to genetically modified organisms - a technique that involves the introduction of foreign genes into the genome of organisms.</em>
GMO modification requires that the genome of a cell is accessed by a foreign gene and in order to do this, the membrane of the cell has to be disrupted to gain entrance by the gene. Animal cells do not have cell walls, and thus, can be accessed directly relevant mechanisms. Plant cells, however, have cell walls and as such, no direct access to the cell membrane can be achieved without having to remove the cell wall first.
Thus, the cell wall is a major factor that makes GMO modification to be different for plants and animals.
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.
Answer:
Polydactyly in the Amish population is an example of Founder effect
Explanation:
Founder effect is defined as loss of genetic variation as it occurs when a new population is formed by small number of individuals that are diverge from the a large population.
Polydactyly is an example of these founder effect that causes formation of extra finger which takes place when a a polydactyly man marry within their own community. As a result,genetic variation does't takes place among them and thus the offspring carry recessive genes which leads to this type of rare genetic disease.
Answer:
B: It occurs only in cells in the reproductive structures of organisms.
