Answer;

-light intensity

-temperature

-chlorophyll density

-water

-carbon dioxide

-soil nutrients

Explanation;

-Photosynthesis is the process by which plants use energy from the sun together with water and carbon dioxide to make organic nutrients such as simple sugars.

-Photosynthesis depends on the amount of light intensity, concentration of carbon dioxide, availability of water, chlorophyll density, temperature and also soil nutrients. All these factors play an important role in enhancing the process of photosynthesis.

A minimum change in sensory intensity that is noticeable to an observer and can be coded into neural messages is known as the

AURORKA [14]

Difference threshold is a minimum alteration in sensory intensity that is noticeable to an observer and can be coded into neural messages. Different threshold is the lowest level of encouragement that is essential to sense that a modification has happened the difference in the intensity between two stimuli that is necessary to yield a just notable difference also known as JND. The just notable difference depends not only on the intensity of the new stimulus but also on the level of stimulation already present which is the more intense the existing stimulus the larger the change must be to be noticeable.

The fraction of offspring that the Punnett square predict will be tall is ¾ (option C).

<h3>What is the punnet square?</h3>

The punnet square is a graphical representation used to determine the probability of an offspring expressing a particular genotype.

The punnet square is used to predict the percentage or proportion of offsprings of a cross that possess a specific genotype.

According to this question, a punnet square shows a cross between two tall pea plants. The allele for tall height (T) is said to be dominant while the allele for short height (t) is recessive.

If two heterozygous genotype crosses i.e. Tt × Tt, the percentage of offsprings that will be tall is 75% or ¾.

Therefore, the fraction of offspring that the Punnett square predict will be tall is ¾.
