Answer the following question given this paragraph: Apocrine secretion accumulates near the apical portion of the cell. That portion of the cell and its secretory contents pinch off from the cell and are released. The sweat glands of the armpit are classified as apocrine glands. Both merocrine and apocrine glands continue to produce and secrete their contents with little damage caused to the cell because the nucleus and golgi regions remain intact after secretion. In contrast, the process of holocrine secretion involves the rupture and destruction of the entire gland cell. The cell accumulates its secretory products and releases them only when it bursts. New gland cells differentiate from cells in the surrounding tissue to replace those lost by secretion. The sebaceous glands that produce the oils on the skin and hair are holocrine glands/cells (Figure 4.11). Q: The sweat glands of the armpit are classified as these? Choices: - mucus glands - pineal glands - adrenal glands - apocrine glands A:
apocrine glands

Answer the following question given this paragraph: The human species has been incredibly successful. In a relatively short period of time, it has colonized almost all of Earth's terrestrial habitats. Unfortunately, human beings have also impacted Earth, its climate, and its environment. Human actions threaten Earth's valuable biodiversity. Q: What incredibly successful species has quickly colonized almost all of earth's terrestrial habitats, but also impacted earth, its climate, and its environment? Choices: - chimpanzees - birds - fish - humans A:
(Answer)
humans
Ques: Answer the following question given this paragraph: After puberty, an egg develops in an ovary about once a month. As you can see in Figure below , the egg rests in a nest of cells called a follicle. The follicle and egg grow larger and go through other changes. Q: What is the nest of cell an egg rests in called? Choices: - mitochondria - pod - epidermis - follicle A:
Ans: follicle

Answer the following question given this paragraph: Viruses are not affected by antibiotics. Several viral diseases can be treated with antiviral drugs or prevented with vaccines. Q: What type of diseases do antibiotics not affect? Choices: - autoimmune diseases - cancer - animal stings - viruses A:
(A).
viruses
Ques:Answer the following question given this paragraph: Cells in our bodies have an intricate mechanism for the manufacture of proteins. Humans have to use other techniques in order to synthesize the same proteins in a lab. The chemistry of peptide synthesis is complicated. Both active groups on an amino acid can react and the amino acid sequence must be a specific one in order for the protein to function. Robert Merrifield developed the first synthetic approach for making proteins in the lab, a manual approach which was lengthy and tedious (and, he won the Nobel Prize in Chemistry in 1984 for his work). Today however, automated systems can crank out a peptide in a very short period of time. Q: Robert merrifield developed the first synthetic approach for making what essential cell substances in the lab? Choices: - cells - acids - lipids - proteins A:

Ans:proteins
Ques: Answer the following question given this paragraph: 18.3 Reconnection and Rates of Speciation Speciation is not a precise division: overlap between closely related species can occur in areas called hybrid zones. Organisms reproduce with other similar organisms. The fitness of these hybrid offspring can affect the evolutionary path of the two species. Scientists propose two models for the rate of speciation: one model illustrates how a species can change slowly over time; the other model demonstrates how change can occur quickly from a parent generation to a new species. Both models continue to follow the patterns of natural selection. Q: What is the name for areas where there is overlap between closely related species? Choices: - mono zones - extinction zones - gap zones - hybrid zones A:
Ans:
hybrid zones
