Q: What is the natural movement called within your intestines? Read this paragraph and choose the correct option from the provided answers: When most of the chyme has been absorbed, the small intestinal wall becomes less distended. At this point, the localized segmentation process is replaced by transport movements. The duodenal mucosa secretes the hormone motilin, which initiates peristalsis in the form of a migrating motility complex. These complexes, which begin in the duodenum, force chyme through a short section of the small intestine and then stop. The next contraction begins a little bit farther down than the first, forces chyme a bit farther through the small intestine, then stops. These complexes move slowly down the small intestine, forcing chyme on the way, taking around 90 to 120 minutes to finally reach the end of the ileum. At this point, the process is repeated, starting in the duodenum. Choices: - proteolysis - progress - fibroblasts - peristalsis A:
peristalsis

Q: What type of waves radiate energy out from an earthquake's focus? Read this paragraph and choose the correct option from the provided answers: Geologists study earthquake waves to "see" Earth's interior. Waves of energy radiate out from an earthquake's focus. These are called seismic waves ( Figure below ). Seismic waves change speed as they move through different materials. This causes them to bend. Some seismic waves do not travel through liquids or gases. Scientists use all of this information to understand what makes up the Earth's interior. Choices: - Microwaves - abnormal - volcanic - seismic A:
(Answer)
seismic

Ques: Q: The development of multi-cellular organisms begins from a single-celled zygote, which undergoes rapid cell division to form this? Read this paragraph and choose the correct option from the provided answers: Cleavage and Blastula Stage The development of multi-cellular organisms begins from a single-celled zygote, which undergoes rapid cell division to form the blastula. The rapid, multiple rounds of cell division are termed cleavage. Cleavage is illustrated in (Figure 43.24a). After the cleavage has produced over 100 cells, the embryo is called a blastula. The blastula is usually a spherical layer of cells (the blastoderm) surrounding a fluid-filled or yolk-filled cavity (the blastocoel). Mammals at this stage form a structure called the blastocyst, characterized by an inner cell mass that is distinct from the surrounding blastula, shown in Figure 43.24b. During cleavage, the cells divide without an increase in mass; that is, one large single-celled zygote divides into multiple smaller cells. Each cell within the blastula is called a blastomere. Choices: - gametophyte - multicell - eukaryote - blastula A:
Ans: blastula

Q: What is the term for a close relationship between two species in which at least one species benefits. Read this paragraph and choose the correct option from the provided answers: Symbiosis is a close relationship between two species in which at least one species benefits. Types of symbiosis include mutualism, parasitism, and commensalism. Choices: - extosis - candiasis - endosymbiosis - symbiosis A:
(A).
symbiosis

Ques:Q: Where do the steps in the water cycle begin? Read this paragraph and choose the correct option from the provided answers: The water cycle does not have a real starting or ending point. It is an endless recycling process that involves the oceans, lakes and other bodies of water, as well as the land surfaces and the atmosphere. The steps in the water cycle are as follows, starting with the water in the oceans:. Choices: - rivers - sky - clouds - the ocean A:

Ans:the ocean

Ques:Q: What is another word for brooding- keeping eggs warm while the embryos develop? Read this paragraph and choose the correct option from the provided answers: After birds lay their eggs, they generally keep the eggs warm with their body heat while the embryos inside continue to develop. This is called incubation, or brooding. In most species, parents stay together for at least the length of the breeding season. In some species, they stay together for life. By staying together, the males as well as females can incubate the eggs and later care for the hatchlings. Birds are the only nonhuman vertebrates with this level of male parental involvement. Choices: - spawning - fertilization - hibernation - incubation A:

Ans:
incubation
