Suppose there are five genes in pumpkins that work additively to affect pumpkin size. A homozygous lowercase allele pumpkin, aabbccddee, weighs 20 lb. Each capitalized allele additively affects the final phenotype by either adding or subtracting weight from the base pumpkin size. The effect of a single capitalized allele is listed in the table. AlleleEffect A +6 B −2 C −3 D +3 E +4 What would the potential size range be for pumpkin offspring produced from the cross between a parent with genotype aaBbCCDdEe and a parent with genotype AaBBCcddEe?

We have heard that seeds are high in protein. If we were to cut open a seed and look for this store of protein under the microscope ,in which cellular structure might we find it? Why does a seed need this store of protein?

Step-by-step answer

P Answered by PhD

Need this store of protein:

The seed consists of three components: embryo, endosperm (sometimes perisperm), and seed-coat. Both endosperm and embryo are the products of double fertilization, whereas the seed-coat develops from the maternal, ovular tissues. The seed habit is a significant advancement in the evolution of higher plants.

Anatomy of seed :-

Need this store of protein: The seed consists of three components: embryo, endosperm (sometimes

Seed storage proteins provide a source of amino acids and reduced N necessary for germination and early growth of the seedling.

Using the term water potential, explain why the onions ; (i)gained mass when soaked in dilute solutions of sodium chloride (ii)lost mass when soaked in concentrated solutions of sodium chloride

Step-by-step answer

P Answered by PhD

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis. Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.
