Explanation:
In the analogy of a cell as a school, lysosomes could be thought of as a teacher.
Because teacher helps students by solving complex problems in simple way and as teacher lysosomes also helps us by breaking down the complex thing in the cell.
Answer:
a prezygotic barrier
Explanation:
Both wild tigers and lions are said to be reproductively isolated.
Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.
The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.
Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.
<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>
The one that is being described above is MY PLATE. My Plate is actually established by the <span>USDA Center for Nutrition Policy and Promotion. This literally looks like a plate and is divided with the necessary food intake that the person should have which includes the five main groups. It is easy to follow most especially for parents who wanted to ensure and serve healthy meals for their children.</span>
Answer:
The options are
A. both homzygous dominant
B. both homzygous recessive
C. both heterozygous
D. one homzygous dominant, one homzygous recessive
The answer is C. both heterozygous
Since it’s in the ratio of 1:2:1 the genotype will be Rr and Rr.
