We can use genetic probability here to determine the chance of producing a gamete that has an allele for dimples. The matrix of probability is shown below where capital letters are attributed to the woman and small ones is that of men. We can see then that the probability of having an allele for dimples is 3/4 having the only chance of not having one is Bb.
Aa
Ab
Ba
Bb
The answer is "D"
The body's first line of defense is also known as Innate immunity and incudes mucous membranes. Both the intact skin and mucous membranes of the body offer a high degree of protection against pathogens.
A good example is the mucous membrane of the respiratory tract. It is lined up with cilia and covered with mucus. The coordinated beating of the cilia drives the mucus up to the nose and mouth where the trapped bacteria can be expelled.
(Lymph nodes and white blood cells belong to the second line of defense, not the first)
Answer:
I think your answer is A. Chemical energy is converted to light energy. I am not 100% sure but i did study this and seems as if this is the only one that makes sense. Hope this helps! If not, sorry :/
Answer:
4. when the ADP is released and the myosin cross-bridge moves to the right in the animation
Explanation:
Cross-bridge formation occurs when the myosin head attaches to the actin while adenosine diphosphate (ADP) and inorganic phosphate (Pi) are still bound to myosin. ADP and Pi is then released, causing myosin to form a stronger attachment to the actin, after which the myosin head moves toward the M-line, pulling the actin along with it. As actin is pulled, the filaments move approximately 10 nm toward the M-line. This movement is called the power stroke, as movement of the thin filament occurs at this step. In the absence of ATP, the myosin head will not detach from actin.
