Answer:
RNA
Explanation:
Transcription is the second stage of central dogma of life (1. replication, 2. <u>transcription</u>, 3. translation).
During transcription, DNA (which is already replicated) is transcribed to RNA. This is because, the genetic information is present within nucleus and thus it is required to be transported outside the nucleus in order to perform key enzymatic functions. Therefore, transcription takes place and the genetic information travels outside in the form of RNA, where ribosomes decode this message to form proteins. The ribosomes make proteins (translation) required for enzymatic functions.
Answer:
all of their children would have a widow's peak hairline
Explanation:
Chris's genotype consists of two dominant widow's peak genes and Janet has two recessive widow's peak genes so the each of the children will inherit one dominant and one recessive widow's peak genes from each parent, making them exhibit "v" shaped hairline and also being carriers for straight hairline.
The given question is incomplete. The complete question is:
In humans, the maintenance of a stable internal temperature is a direct result of___________.
a. detection of and reaction to stimuli in the environment
b. digestion of starches and absorption of protein from the internal environment
c. diffusion of water and excretion of glucose to the external environment
d. transport of ATP and locomotion through the environment
Answer:
a. detection of and reaction to stimuli in the environment
Explanation:
Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.
On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.
Answer:
When finding the probability calculation, you can divide the number of events by the no. of the possible outcomes, and that can give you the probability of the event from there. If you use this strategy, you can determine the outcome from there! Hope this helps. ^_^
A+t+c+g = 100%
a:t = 1
30+30+c+g = 100
100-60 = 40
40/2 = 20.
The answer would be 20%
