Answer: 1-TT, 2-Tt, 3-Tt, 4-tt
Explanation: It is pretty simple. you just have to match every letter together. Also, the genotype of this is 50% Tt (which is crossbred), 25% TT (which is tall), and 25% tt (which is short).
I hope this helped you out!
Answer:
It just seems like you're supposed to give four pieces of evidence of natural selection. If you're still confused, you can always ask your teacher.

Answer:
When the frequency of stimulation of a muscle increases -without it having the opportunity to relax- a process called summation (addition) occurs, promoting an increase in the generation of force in the isolated skeletal muscle.
Explanation:
Summation is a phenomenon that occurs as a consequence of the arrival of successive stimuli that produce the contraction of the skeletal muscle before it achieves its partial or total relaxation, between subsequent stimuli.
<em>When the summation occurs in the muscle, the force generated on it increases its magnitude proportionally to the number of stimuli received, maintaining the muscle contraction in time</em>.
Tetany is the prolonged contraction of a muscle in an abnormal way, by the summation of stimuli received , as some bacterial toxins can produce. The summation can be temporary -when multiple stimuli reach the muscle in a determined time- or spatial, when the amount of stimuli activates a greater amount of motor units.

Answer:
In favourable environments you might find birds laying more eggs, and a greater likelihood of multiple successful clutches. There are also birds like Bald Eagles, that start mating in early January and can lay eggs before Spring officially comes. 13. Food Availability. The amount of food available has an affect on bird mating cycles.
