Answer:
B) embryology
Explanation:
Embryology by definition is the branch of biology and medicine concerned with the study of embryos and their development. All the other answer choices would not fit what your question is looking for. A botanist is someone who studies plants. An obstetrics is someone who studies childbirth. And internal medicine is completely out of the question.
The provided question is not complete as it lacks the appropriate choices for the answer, however, the correct choices are:
Which of the following will NOT prevent many bacterial infections?
a. allowing foods to cool completely before refrigerating
b. washing hands and surfaces with soap and water
c. storing food in a refrigerator
d. heating objects to very high temperatures
Answer:
The correct answer would be - allowing foods to cool before refrigerating.
Explanation:
Bacterial infections can be prevented by many processes such as washing hands with soap and water thoroughly for a minimum of twenty seconds. Storing food in the refrigerator helps the food to be fresh and infection-free from various microbes.
Heating the food, water, and tools to very high temperature helps in killing the bacteria present in these and leads to bacterial infection. Cooling the food before storing it in the refrigerator may cause bacteria to infect the food.

in the chemical bonds holding the sugar molecule together
O In the chemical bonds holding the phosphate groups together
Energy in ATP is stored in the chemical bonds connecting the phosphate groups. The release of energy occurs when these bonds are broken, specifically between the second and third phosphate groups.
Energy in ATP (Adenosine Triphosphate) is stored in the chemical bonds holding the phosphate groups together. This molecule consists of a nucleoside (adenosine) attached to three phosphate groups. When ATP is broken down into ADP (Adenosine Diphosphate) and inorganic phosphate, a considerable amount of energy is released. This energy release happens due to the breaking of a high-energy bond between the second and third phosphate groups, which are negatively charged and thus naturally repel each other.

Explanation:
Answer:
non-foliated, metamorphic
Explanation:
Unlike quartz, an igneous rock which forms a crystal from magma or as a precipiate near hydrothermal vents, quartzite is formed from applying heat and pressure to sandstone, thus it is metamorphic. The intense conditions during its formation tightly compresses and interwinds the quartz grains, the resulting rock becomes hard and dense. As a non-foliated rock, quartzite does not show repeated parallel bands and it breaks across grains to split into flat layers.
Answer:

Explanation:
Quartzite
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.
Texture - granular.
Grain size - medium grained; can see interlocking quartz crystals with the naked eye.
Hardness - hard.
Colour - variable - pure quartzite is white but quartzite exists in a wide variety of colours.
Mineralogy - quartz.
Other features - generally gritty to touch.
Uses - pure quartzite is a source of silica for metallurgical purposes, and for the manufacture of brick; as aggregate in the construction and roading industries; as armour rock for sea walls; dimension stone for building facings, paving etc.
