Answer:
Allele
Explanation:
A gene is a stretch of DNA that code for a specific protein. A gene can exist as two or more alternative forms. These alternative forms of a gene are called as alleles. The alleles are responsible for presence of variants of a particular genetic trait.
For example: The gene for plant height has two possible forms, i.e. two alleles. These are symbolized as "T" and "t". The allele "T" impart tallness while allele "t" imparts dwarfism to the plants.
Answer:
Smaller particles and energy
Explanation:
Digestion of food refer to breaker down of large food components into smaller particles. When food is ingested or swallowed, it go through slot of processes where it is acted upon by enzymes and it is then breakdown into smaller particles which can be absorbed by the villi in the small intestine.

Answer: B
Explanation: It is the question 2 that can be answered using scientific process. scientists can better explain the effect of plastic bags on birds.
The other question can be answered by research or logics.
Answer: Kinetic energy depends on m, v in the expression, 1/2xmxv²
Explanation:we can ask how kinetic energy is changing if velocity is doubled, how kinetic energy changes if velocity changes. you can change the value of m, v in each question you ask.
