<span>Option 1: Sunlight is the energy source for plant photosynthesis.
True: In photosynthesis, plants convert light energy from the sun to chemical energy in the form of glucose.
Option 2: Chlorophyll is contained in organelles called chloroplasts.
True: Chlorophyll in the chloroplasts is what allows many wavelengths of light for be absorbed and used for photosynthesis.
Option 3: A by-product of photosynthesis is carbon dioxide.
False: Plants require carbon dioxide to create glucose, and produce oxygen as a by-product.
Option 4: Roots have tiny root hairs that maximize the plant's ability to absorb water.
True: Root hairs are very important for the absorption of nutrients and water by plant roots. </span><span /><span>

Answer:
3 long tails : 1 short tail
Explanation:
This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.
According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:
Tt - T and t
Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.
Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

<span>Survival of at least a few members of a population after a major environmental change is most dependent on 3) variations in many different traits in many individuals in the population.
Variation is important for a species which wants to survive huge changes in the environment. If they cannot adapt to their new surroundings, they won't be able to survive. This is where variation comes in - it enables a species to develop new techniques and traits necessary for survival.
