Answer the following question given this paragraph: Burning forests also releases carbon dioxide into the atmosphere. Other human activities release greenhouse gases into the atmosphere. For example, growing rice and raising livestock both produce methane. Q: Burning forests, growing rice and raising livestock all cause a release of what into the atmosphere? Choices: - oxide gases - carbonate gases - glucose gases - greenhouse gases A:
greenhouse gases

Answer the following question given this paragraph: Hemoglobin is an example of a transport protein in the blood. You can see how it works in Figure below . The heme parts of a hemoglobin molecule bind with oxygen. Each red blood cell has hundreds of hemoglobin molecules. This is how oxygen is carried in the blood to cells throughout the body. Q: The heme parts of a hemoglobin molecule bind with what element? Choices: - hydrogen - carbon - nitrogen - oxygen A:
(Answer)
oxygen
Ques: Answer the following question given this paragraph: Behavioral isolation occurs when the presence or absence of a specific behavior prevents reproduction from taking place. For example, male fireflies use specific light patterns to attract females. Various species of fireflies display their lights differently. If a male of one species tried to attract the female of another, she would not recognize the light pattern and would not mate with the male. Other prezygotic barriers work when differences in their gamete cells (eggs and sperm) prevent fertilization from taking place; this is called a gametic barrier. Similarly, in some cases closely related organisms try to mate, but their reproductive structures simply do not fit together. For example, damselfly males of different species have differently shaped reproductive organs. If one species tries to mate with the female of another, their body parts simply do not fit together. (Figure 18.19). Q: What occurs when the presence or absence of a specific behavior prevents reproduction from taking place? Choices: - spontaneous mutation - natural selection - primary speciation - behavioral isolation A:
Ans: behavioral isolation

Answer the following question given this paragraph: Figure 17.12 Thyroid Gland The thyroid gland is located in the neck where it wraps around the trachea. (a) Anterior view of the thyroid gland. (b) Posterior view of the thyroid gland. (c) The glandular tissue is composed primarily of thyroid follicles. The larger parafollicular cells often appear within the matrix of follicle cells. LM 1332. (Micrograph provided by the Regents of University of Michigan Medical School ©️ 2012). Q: What gland is located in the neck, where it wraps around the trachea? Choices: - adrenal gland - salivary gland - pituitary gland - thyroid gland A:
(A).
thyroid gland
Ques:Answer the following question given this paragraph: Individual nucleotides can be linked together through their phosphate groups to form nucleic acid polymers. Once constructed, DNA generally exists as two strands that are linked together by hydrogen bonds, producing a double-helical structure (see Figure below ). Q: Individual nucleotides can be linked together through their phosphate groups to form? Choices: - atoms - nitrous acid polymers - dna - nucleic acid polymers A:

Ans:nucleic acid polymers
Ques:Answer the following question given this paragraph: The atoms of a compound are held together by chemical bonds. Chemical bonds form when atoms share electrons. There are different types of chemical bonds, and they vary in how strongly they hold together the atoms of a compound. Two of the strongest types of bonds are covalent and ionic bonds. Covalent bonds form between atoms that have little if any difference in electronegativity, and result when atoms share electrons. Electronegativity is the power of an atom to attract electrons toward itself. Ionic bonds , in contrast, form between atoms that are significantly different in electronegativity. An ion is an atom that has gained or lost at least one electron. Ionic bonds form between ions of opposite charges. Q: The atoms of a compound are held together by what type of bonds? Choices: - covalent - mineral - radiation - chemical A:

Ans:
chemical
