gregori [183]

Answer:

The correct answer would be -

17. 50% chances of round offspring

18. 25% chances two copies of dominant allele in the genotype of offspring

Explanation:

17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.

S for square trait and s for a round trait then

    S     s

s Ss    ss

s Ss    ss

Thus, the correct answer is 50 percent as there are only two copies of ss.

18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -

     P    p

P   PP  Pp

p   Pp  pp

There is only one out of four rue-breeding dominant offspring will be produced.

GaryK [48]
<span>Plants use green pigments called chlorophylls to trap light energy. The
chlorophylls give a plant its green color. Inside the cells that have
chloroplasts, the light energy is used to make a simple sugar called glucose.
The process by which plants use light energy to make glucose is called
photosynthesis.

During this process of sugar production, carbon dioxide combines with water to
form glucose and oxygen is released. Oxygen that is produced in photosynthesis
is given off as a gas. If a lot of oxygen is being given off, photosynthesis is
occurring rapidly. If little oxygen is being given off, photosynthesis is
occurring slowly. The amount of trapped light energy and the amount of carbon
dioxide available affects the rate of photosynthesis.

The purpose of adding sodium bicarbonate powder to the water increases the
amount of carbon dioxide in the water.                 hope this helped

This investigation can be performed with water plants grown in many parts of
the world, except regions that have permanent ice.</span>
