Van Helmont concluded that most of the mass the plant gained had come from water.
Answer:
The movement pushes food and liquid through your GI tract and mixes the contents within each organ. The muscle behind the food contracts and squeezes the food forward, while the muscle in front of the food relaxes to allow the food to move. The digestive process starts when you put food in your mouth.
Red eyes are not gender specific and 100% of the offspring
would have red eyes would have red eyes if the gene were on autosome.
Explanation:
If the eye colour is not sex-linked and the traits are on the autosomes.
Genotype for male = XWY or XwY
Genotype for female = XWXW, XWXw. XwXw
Punnet square:
cross between red eye male and white eye male
XW Y
XW XWXW XWY
XW XWXW XWY all oofspring red eye
cross between white eye male and red eye female
Xw Y
XW XWXw XWY
Xw XwXw XwY 1 red male:1 white male: 1 red male : 1 white female
if mother has recessive gene all the male will be white eyed.
all the female progeny will have red eye because father had dominant red eye.
The red eye is dominant over white hence dominant trait will appear.
Answer:
Atrial contraction, or “atrial kick,” occurs at the end of diastole just before the closing of the mitral valve and after passive flow has reached the diastasis. Normally, greater than 75% of flow occurs during the passive portion of diastole.
Answer:
True
Explanation:
Gel electrophoresis is a technique that is commonly used in the laboratory to separate charged molecules, like DNA, according to their size. The results of restriction digestion can be observed using this process. Restriction Digestion involves the process of cutting DNA molecules into smaller fragments using special enzymes called Restriction Endonucleases. And this way any inhibition of the restriction enzymes which prevents digestion can be observed and controlled.
