Answer:

Interrupt the long winter nights with a brief period of light.

Explanation:

Long day plants, also called short night plants, flower when the dark period is equal or less than the critical period specific for the species. These plants normally flower in summers when nights are short and days are longer. Winters have a long dark period and do not support flowering in shirt night plants.

A continuous dark period is critical for flowering. A short night plant can flower in winters (having longer dark periods) if the dark period is interrupted by exposing the plant with a flash of light. To make short night plants, such as iris to flower in winters, the plant should be given short period of light after completion of critical dark period.

Unmyelinated axons and neuronal cell bodies make up the majority of the grey matter.

The processes that emerge from the cell bodies of neurons and transmit messages between those cell bodies are known as axons.

These axons are primarily unmyelinated in the grey matter, which means that myelin, a whitish-colored, fatty protein, is not covering them.

In the brain, the grey matter is used to process information. Grey matter structures analyze signals produced by sensory organs or other regions of the grey matter.

This tissue sends sensory (motor) stimuli to the central nervous system's nerve cells, where synapses cause the nerve cells to respond to the stimuli. Through myelinated axons, which make up the majority of the white matter in the cerebrum, cerebellum, and spine, these impulses travel to the grey matter.

If one strand of DNA double helix has the following nucleotide sequence ATCGGTCAAGCTAGG what would the dna complementary stand r
joja [24]

Answer:

TAGCCAGTTCGATCC

Explanation:

In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).

A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).

If we have the strand:

ATCGGTCAAGCTAGG  

We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:

TAGCCAGTTCGATCC

Suppose a female began menstruating at age 12 and stopped menstruating at age 55. if she never became pregnant and her menstrual
Arte-miy333 [17]

Answer:

561

Explanation:

This is math so I got you.

This is just going to subtract 12 from 55 since we don't now when during her 12th year of age she started or when during her 55th year f age she ended.

55 - 12 = 43, so about 43 years.  Also not going to account for leap years.  So we are just going to say each year had 365 days.  so 43 years and 365 days per year = 15695 days.

If her cycles were each about 28 days we divide the total number of days by 28 and that tells us about how many cycles there were.

15,695 / 28 = 560.5 which I will round to 561

561 cycles means 561 eggs if my biology knowledge is as accurate as I think it is.
