Answer:
The plants growing on the left will be able to synthesize more required molecules in a better way as compared to the plants on the right.
As plants, on the left, will be receiving all the essential nutrients that is required for functioning properly hence, the will be bale to synthesize all the complex molecules required for growth and surviving.
On the other hand, plants on the right side, will not be able to grow properly as they will not have the required amount of nutrition.

Explanation:
The missing options of this question are:
A. Artificial selection
B. Transgenics
C. Bioreaction
D. Recombination
The correct answer is option B. "Transgenics"
Transgenics is a term used to describe the artificial insertion of one or more DNA sequences to an organism that would normally not have it. In this example, the term transgenics applies to the cows that serve as hosts for the production of the spider silk.

Answer: Substances that are protein based cannot cross the lipid cell membrane, but can exert their effect by binding to the proteins based receptors present on the lipid bilayer.
Explanation:
Hormones such as calcitonin , Parathyroid hormone and pituatry horomones are proteins and water soluble.They cannot cross lipid bilayer but can bind to ligand binding protein receptors.
These receptors are protein macromolecules that are specific in nature for specific hormones.
After binding to the receptors, these hormone-recpetor complexes activate second messengers and regulate the downstream effects.
