Chemistry deals with the properties, composition, and structure of substances, the transformations they undergo, and the energy that is released or absorbed during these processes.
Answer:
D - Birthrate exceeds death rate
Explanation:
A - Death rate exceeds birthrate
This one means that the population will fall, due to too many people dieing.
B - Emigration rate exceeds birthrate
More people are leaving than being popped out, so decrease.
C - Death rate exceeds immigration rate
This one is so-so. It is possible that the population will grow, but this is not the best answer.
Answer:
Germline mutation
Explanation:
A germline mutation is a genetic change produced in the gametic-germline cells (i.e., male and female gametocytes). The mutations in the germline are inherited in the next generation, while changes in somatic cells are not inherited. Moreover, the germline mutations may occur either before the fertilization or during embryonic development (zygote morula, blastula and gastrula). This type of mutation may be induced by both endogenous (e.g., oxidative DNA damage) and exogenous (e.g., exposure to UV light) factors.

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.
