It is important to note that the graph has 0 solar intensity for a long part of the day; around 16 hours. Only from 8 to 16 hours do we have significant sunlight.
This means that the length of day is very short during this time of the year;
The length of the day changes throughout they year; day is equal to night (12 hours each) during the solstices on March 21 and September 23 but during summer day is longer than night in the northern hemisphere; during winter it is smaller. THe smallest daylength is at December 21st (in the northern Hemisphere). This phenomenon is due to the tilt of the axis of the earth.
The correct answer is December 21; (if we talked about a place in the southern hemisphere, the answer would be March 21).
<span>The four biological macromolecules are carbohydrates, lipids, proteins and nucleic acid. These macromolecules are known as polymers and are built when monomers join together by a process known as the dehydration reaction. The dehydration reaction is a chemical reaction that produces water (H2O) and the result is the covalent bonding of the two monomer molecules. The monomer molecules consist of nutrients found in the soil, as in the case of plants, and the intake of food as in the case of animals.

Explanation:
Genetic evolution is the meaning of biologic life, in that it is the why and how of it, as well as the stock of future biological existence. The genes that survive -- and in turn the organisms they make -- are the winners in the existence game. ... We owe our existence to this process, and our future depends on it.

Explanation:
The pituitary gland is a small gland that divides into two distinct portions, the anterior and posterior lobes, and is located at the base of the brain.
The anterior pituitary, also known as the adenohypophysis, secretes six important peptide hormones, they are:
- The growth hormone;
- Adrenocorticotropin;
- The thyroid stimulating hormone;
- Prolactin;
- Two gonadotropic homons - FSH and LH;
Oxytocin is not a hormone produced by the anterior pituitary but by the posterior pituitary, which is known as the neurohypophysis.
