<h2>A) is the correct option </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
- In the given example of rabbits, those that strictly eat grass will even survive after drought because plants will try to keep themselves green and there will be no production of berries and flowers hence these rabbits will shift their food source to green plants and will be favored
- But those rabbits those that strictly eat berries and flowers will not be able to survive because they were strictly dependent on berries and flowers for their food as a result they will be unfit and natural selection will be against those rabbits
Answer:
codominance because the offspring’s scale color includes both parents’ scale colors
Explanation:
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
D) egg in Kayro syrup
Explanation:
An egg in Kayro syrup will experience plasmolysis. During the process of plasmolysis a body loses water to another one at a higher concentration. Fresh water organisms suffers plasmolysis because in salt water, the concentration of dissolved salt in the water is high and this makes the water hypertonic to their body.
- In a hypertonic solution, the egg will lose water and begins to shrink in the Kayro syrup.
- The Kayro syrup is hypertonic to the egg and by so doing, it will lose water to it.

Answer:
Through this experiment we study the process of photosynthesis.
• In the begining the leaf disks's tissue has oxygen, this allows them to float.
• Then, in the experiment we infiltrate the leaf disks with a solution that has bicarbonate, and as a result their density changes (it increases) and so the leaf disks sink.
• Once the disks are on the bottom and we direct the light to them the process of photosynthesis starts, being the bicarbonate the source of carbon for the process.
• As we know a product of the photosynthesis proces is oxygen, so when it is released into the leaf disks the overall density changes again and the disks rise.
So as we can see, in this experiment the purpose of the bicarbonate is being the source of carbon for the process of photosynthesis that occurs in the leaf disks.
