Answer:
1/4 or 1/2 depending on mating partner of F2
Explanation:
Assuming that the F1 parent Rr mated with a plant with the RR, Rr or rr genotype the F2 offspring would have the following genotypes:
Rr x RR= 1/2 RR, 1/2 Rr
Rr x Rr = 1/4 RR, 1/2 Rr, 1/4 rr
Rr x rr = 1/2 Rr, 1/2 rr
The F2 generation with the RR genotype could not be the parents of the F3 generation because to have individuals with the rr genotype the F2 generation would have to mate with a plant that is either Rr or rr in which case the fraction of the population with the stripe rust phenotype will either be 1/4 or 1/2, respectively.
Answer:
<u>Reproductive strategies are not an either/or sort of affair; some organisms fall somewhere between semelparity and iteroparity reproduction. In addition to various reproductive strategies, organisms differ in their survivorship strategies. Some organisms are at high risk of dying early in life, but if they can survive long enough, they have a decreasing probability of dying as the years go on. Well, to a point anyway. Other organisms have a steadily increasing probability of dying while still others live for a long time with the probability of dying only increasing dramatically after a certain (often old) age.</u>

Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.
Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.
<h3><u>Answer;</u></h3>
A skinner chamber
A <u>skinner chamber</u> is a chamber that isolates the subject from the external environment.
<h3><u>Explanation;</u></h3>
- A skinner chamber or skinner box an enclosed chamber which contains a bar or key that an animal can press or manipulate in order to obtain food or water as a type of reinforcement.
- <em><u>This box was used by Skinner in his experiments concerning Operant conditioning. From the experiments that he conducted he realized that the important part of any operant conditioning id recognizing the operant behavior and the outcome resulted in that particular environment.</u></em>
