Answer:
Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. ... As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!

Answer:
The cells of living things also get energy by "burning." They "burn" glucose in the process called cellular respiration. Inside every cell of all living things, energy is needed to carry out life processes. Energy is required to break down and build up molecules and to transport many molecules across plasma membranes.

Explanation:
Answer: insertion
Crossing over is when homologous* chromosomes exchange genes, resulting in gene combinations.
Deletion is when a base pair is deleted from DNA. Insertion is when a base pair is added to DNA. Both insertion and deletion are serious because every amino acid beginning at the mutation will most likely be incorrect. This will lead to a nonfunctional protein.
Base-pair substitution is a substitution of one base pair for another in DNA. The effects of this may be a silent** point, missense*** point, or nonsense**** point.
-------
<em>*A pair of matching chromosomes. They have the same genes but can have different versions.</em>
<em>**A special case where no amino acids are affected.</em>
<em>***Affects one animo acid. The whole protein structure and function may or may not be disrupted. </em>
<em>****Results in a stop codon that shortens the protein.</em>
