Noctiluca scintillans, commonly known as the sea tinkle and also published as Noctiluca miliaris, is a free-living, nonparasitic, marine-dwelling species of dinoflagellate that exhibits bioluminescence when disturbed (popularly known as mareel). Its bioluminescence is produced throughout the cytoplasm of this single-celled protist, by a luciferin-luciferase reaction in thousands of spherically shaped organelles, called scintillons. Nonluminescent populations within the genus Noctiluca lack these scintillons.
The answer is D. Light bends as it passes from one medium to another
Answer:
When the sun, moon and earth are at right angles, this is called a neap tide.
When the sun, moon, and earth are parrallel to each other, this is called a spring tide.
Explanation:
There are two types of tides spring tide and neap tide.
A spring tide occurs when the sun and moon are parallel to each other. This usually happens during periods of full and new moon, which are the moments that the moon can form a straight line with the sun, causing the gravitational force to interfere with the tide.
The neap tide, on the other hand, happens when the sun, moon and earth are at right angles. This moment occurs between the waxing and waning moons, where the sun and moon are at right angles and the earth is used as a vertex of that angle. In this type of tide the gravity of the sun becomes more influential than that of the moon.
The answer is A p is the frequency of the dominant allele. So the p squared would be the frequency of the homozygous dominant allele because homo means the same.
Answer:
<h2>A</h2>
Explanation:
As given;
Solid color is dominant on spotted color,
so A is dominant on a.
black coat color (B) is dominant on red (b) color
so B is dominant over b.
cross between two solid black dogs several times and their offspring were 18 solid black and 5 spotted black puppies. so the parents will be Аа Bb x AA Вb, due to the effect of dominant.
