Answer:
For you to answer to this question you need to think at the alleles, so let's say the dominant one is A, and the other one is a.
Explanation:
With that said, we need to take a look at a proportion below:
Let's imagine the possibility of both flowers being Aa, so we have Aa x Aa right? Okay, now let's do the math
AA Aa Aa aa
Now it's time for us to check the information to see if it matches with the question, we have 600 blue to 200 red flowers, that means 3/1 because: 600/200 = 3/1. So for each red we'll have 3 blue flowers. So this is correct, but we still need the answer, how many of them are heterozygous, well, if this is the right path to follow, it'll be like this:
AA Aa Aa (not counting the aa because they're red)
These are the blue ones, but we need the heterozygous right? so the relationship will be like: for each AA we'll have 2 Aa, doing the math the answer will be 400.
There are many grains of starch in the cortex because it represents the reserve food material of plants.
This source of food material is consumed during plant metabolism, as food when plants are under stress, or as an energy source in seed germination and early seedling stages.
The cortex, in plants, is a vascular tissue responsible for the transport of food (processed sap) from the leaves to the rest of the plant .
Starch grains are the most common solid particles that plant cells develop within plastids.
Assimilation starch is a temporary product of photosynthesis and is formed in chloroplasts, while reserve starch is formed in amyloplasts, which are contained in parenchymal cells of the cortex, in vascular tissues of stems and roots, in the pith of stems, in fruits, leaves, fleshy cotyledons and in modified stems, such as tubers and rhizomes.
Starch is the main energy and carbon reserve in plants, supplying the energy and carbon skeletons necessary for the plant's metabolism during periods of darkness, when photosynthesis is inactive.
Therefore, we can conclude that starch grains (ergasstic substances) are found in abundance in the cortex because it represents a reserve of essential molecules for the functioning and maintenance of the cellular structure.

Explanation:
Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
He is correct, the correct answer is
B. club mosses, horsetails, and ferns.
It is very important to control the conditions of an experiment because FAILURE TO DO THIS WILL MAKE THE RESULTS OF THE EXPERIMENT INVALID.
A controlled experiment refers to an experiment that is conducted under controlled conditions. Conducting experiments under controlled conditions helps scientists to minimize the changes in all other variables with the exception of the ones been tested.
