"ribosomes".
(I'm not experienced in this subject but I hope I could help!)
Salivary glands produce large amounts of enzymes, such as amylase, that are secreted out of the cells. Ribosomes are the organelles which are more abundant in cell over others. Thus, the correct option is B.
What are Ribosomes?Ribosome are the cell organelles which are abundant in the cells over the other organelles. Ribosomes are found attached to the surface of the Endoplasmic reticulum, these structures are called Rough Endoplasmic Reticulum (RER).
Ribosomes are the cellular machinery which are responsible for making proteins through the process of translation. There are many ribosomes in each cell, which are made up of two subunits. These two subunits include one large and one small subunit which lock around the messenger RNA (mRNA) and then travel along the length of the mRNA molecule reading each three-letter codon which encode different amino acids and hence proteins.
Therefore, the correct option is B.

An organ or tissue may be better able to resist damage from hypoperfusion if the:_________
An organ or tissue may be better able to resist damage from hypoperfusion if the: body's temperature is considerably less than 98.6°F (37.0°C)
What is hypoperfusion?A word used to denote "a decreased amount of blood flow" is hypoperfusion. We can refer to ischemia that arises as "hypoperfusion" when there is insufficient blood flow. Low blood pressure, heart failure, or blood volume loss are some of the causes of hypoperfusion. Lightheadedness, dizziness, headaches, nausea, exhaustion, and shortness of breath are typical symptoms that are made worse by being upright and made better by lying down. Thromboemboli are encouraged to form by hypoperfusion. Severe occlusive lesions result in hypoperfusion, which alters the quantity and turbulence of blood flow and encourages the development of both white and red thrombi, which are the building blocks of emboli.Learn more about the hypoperfusion with the help of the given link:

The hormone produced by the corpus luteum that is the primary ovarian hormone after ovulation is __?
The hormone produced by the corpus luteum which is the primary ovarian hormone after ovulation is progesterone.
Corpus luteum is a gland that is produced when an egg is released from the ovary. Progesterone hormone is produced by the corpus luteum as well as the adrenal glands and placenta. Ovulation occurs as a result of an increase in the luteinizing hormone. The corpus luteum is formed after the release of the egg which then produces progesterone hormone.
Progesterone is an important hormone in maintaining pregnancy which belongs to the class of estrogens as it prepares the uterus lining for the implantation of the fertilized egg. It also plays important role in lactation and fetal development. Progesterone is also involved in maintaining the secondary sex characteristics of females.

Describe each of the cycles in nature. Identify where each cycle is found, how organisms use them, and what key words relate to them.
The correct answer is four cycles are (1) The Water Cycle or Hydrologic Cycle (2) The Carbon Cycle (3) The Nitrogen Cycle (4) The Oxygen Cycle.
The hydrologic cycle is the continuous movement of water in the Earth-Atmosphere system. The water cycle is defined as the movement of water from the ground to the atmosphere and back again.
The carbon cycle describes the movement of carbon from the atmosphere to soils, living creatures, the ocean, and human sources.
The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
The entire cycle can be summarized as follows: the oxygen cycle begins with photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and then links back to the process of photosynthesis.

Why are some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain?
Answer:
Some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain because they have too much peptidoglycan in their cell walls.
Explanation:
Across most types of bacteria, the cytoplasmic membranes is encased in a hard material called peptidoglycan. It helps maintain cell shape all across the life cycle and shields bacterial cells against environmental stress. The production of peptidoglycan has a significant role in controlling bacterial cell division. The bacterial cell wall's peptidoglycan plays a structural role by providing structural support and balancing the cytoplasm's osmolarity. Additionally, peptidoglycan participates in binary fission throughout bacterial cell division. Christian Gram, a microbiologist, developed a test in 1884 which might identify whether a bacterium possessed a strong, mesh-like membrane known as peptidoglycan. Numerous bacteriophages, eukaryotic, and bacteria all generate peptididoglycan hydrolases.

Which class of antidiabetic drugs inhibits alpha glucosidase and delays glucose absorption?
Alpha-glucosidase inhibitors are a class of antidiabetic drugs that inhibits alpha-glucosidase and delays glucose absorption.
Alpha-glucosidase inhibitors are abbreviated as AGIs. AGIs inhibit the absorption of carbohydrates in the small intestine by inhibiting the action of enzymes such as alpha-glucosidase. Alpha-glucosidase is an enzyme that converts complex carbohydrates (e.g. Starch) into simple absorbable carbohydrates like glucose. Other enzymes that perform a similar function include sucrase, maltase, glucoamylase, and isomaltase.
Acarbose is the most commonly used Alpha-glucosidase inhibitor taken orally. AGIs are initiated with a lower dosage taken three times with the meal. Acarbose inhibits the action of enzymes like alpha-amylase, maltase, sucrase, and dextranase.
Due to the action of AGIs to inhibit the carbohydrate converting enzymes, they are named so. And with this preference, AGIs are used to delay glucose absorption.
