A black-and-white TV has a single electron gun, a cathode Ray tube
Diarrhea can be caused by indigestion, a raw meal, or little bacterias found in almost anything we swallow, but if it doesn´t stop in a 12 hours period, it may be caused by some infection or a worse condition that need to be seen by a doctor, is this case, the nurse is concerned because Aidan is severely weakened, signal that is dehydrating very fast and that could cause him a worse condition such as hypotension, hypoglycemy or even losing consciouness.

If the beaker was not cleaned, starch could have been in it.
Answer:
a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1049 / 2420 = 0.433
b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1371 / 2420 = 0.567
c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 649 / 2020 = 0.321
d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 1371 / 2020 = 0.679
e) migration is gene flow
Explanation:
Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).
Answer:
Photoperiod signifies towards the time that an animal or a plant gets exposed to light in a twenty-four-hour duration. Different types of plants need different durations of light exposure to follow their respective life cycles.
On the basis of getting exposed to light differently, the plants are differentiated into short-day plants, long-day plants, day-neutral plants, and intermediate-day plants. The day-neutral plants will undergo flowering at any length of the day, given that there is the availability of minimum amount of light, which is essential for usual growth. For example, beans, tropical plants, cotton, and others.
On the other hand, the intermediate-day plants will not flower if the days are too long or too short, like different varieties of grasses.
