Answer:
1/4 or 25%
Explanation:
Let us assume that the fruit color trait in the tomato is represented by R and r. The dominant color red would be represented by R while the recessive color yellow would r.
If a true-breeding red fruit tomato (RR) is crossed with a true-breeding yellow fruit tomato (rr), the F1 would be thus:
RR x rr
Rr Rr Rr Rr
Since R is dominant over r, all the F1 offspring would produce red fruits with the genotype Rr.
At F2:
Rr x Rr
RR Rr Rr rr
RR and Rr = red
rr = yellow
<em>Hence, the proportion of the F2 offspring expected to be yellow would be </em><em>1/4</em><em> or</em><em> 25%</em><em>.</em>

Answer:
gravitational potential energy
The skier possesses gravitational potential energy at the top of a slope, which transforms into kinetic energy as he moves down the slope.
Answer:
So they can breathe
Explanation:
Without oxygen the fish can't breath, they would then suffocate and die.
Sorry if your asking for a more detailed answer, but I'm not sure what else to say
Answer:
Maintaining a rich variety of genetic material that can lead to discoveries useful for humans can be ensured by preserving biodiversity.
Explanation:
Options for this question are:
- <em>Preserving biodiversity
.</em>
- <em>Increasing cloning
.</em>
- <em>Asexual reproduction
.</em>
- <em>Selective breeding.</em>
Biodiversity refers to the number of different living organisms that exist, and which are the product of evolution, those that have multiple ways of interacting, shaping life on the planet.
The human being is part of biodiversity, considered a natural heritage of the world and an element that provides balance to the biosphere.
An important characteristic of biodiversity is that it contains the different genetic information of each living being, each one of which is a functional element on which the maintenance of life on the planet depends, as well as the reservoir of the world's genetic potential, so it is necessary to guarantee its preservation.
