The definition of a point mutation states that a mutations is a point mutation if it affects only one or few nucleotides in the DNA product. We have that DNA is read in frames of 3 nucleotides. If the starting point of one frame is changed, then all frames are changed because the frames are grouped by 3 nucleotides. We have that frameshift mutations not point mutations because a shift in the reading frame affects how the rest of the DNA is read. This is the case for insertion and deletion of a nucleotide; it changes the number of nucleotides and shifts the reading frame by 1. A missense mutation is a point mutation though; it involves substituting a nucleotide with a wrong one. It involves an error only in one place and it does not change the reading frame so it affects only one nucleotide.
Answer:
A. Radiant energy from the sun, which transforms into chemical energy
The question does not have the option which are:
depleted in red light; inactive form
enriched in red light; active form
depleted in red light; active form
enriched in red light; inactive form
depleted in red light; inactive form
Answer:
depleted in red light; inactive form
Explanation:
The understory is the lower portion of the forest canopy which is characterised by the shade-tolerant species of the plants.
The light that reaches the lower portion or in the understory is depleted in the red light wavelength.
The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.
Thus, the selected option is correct.
Photosynthesis<span> makes the glucose that is used in </span>cellular respiration<span> to make ATP. The glucose is then turned back into carbon dioxide, which is used in </span>photosynthesis<span>. While water is broken down to form oxygen during </span>photosynthesis<span>, in </span>cellular respiration<span> oxygen is combined with hydrogen to form water.

Explanation:
Most spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive black hole. Approximately two-thirds of spiral galaxies also contain a bar structure through their center, as does the Milky Way.
