Answer the following question given this paragraph: Muscle tissue in the walls of internal organs such as the stomach and intestines is smooth muscle . When smooth muscle contracts, it helps the organs carry out their functions. For example, when smooth muscle in the stomach contracts, it squeezes the food inside the stomach, which helps break the food into smaller pieces. Contractions of smooth muscle are involuntary. This means they are not under conscious control. Q: What will the contraction of smooth muscles help organs do? Choices: - fine motor movements - move joints - move across distances - carry out functions A:
carry out functions

Ques: Answer the following question given this paragraph: The four planets closest to the SunMercury, Venus, Earth, and Marsare the inner planets or terrestrial planets ( Figure below ). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets. Q: Where are the terrestrial planets located, in relation to the sun? Choices: - farthest - To the left - To the right - closest A:
Ans: closest

Q: What is the structure which hangs from a newly hatched salmon larva? Choices: - air sac - liquid sac - stomach sac - yolk sac A:
(A).
yolk sac
Ques:Answer the following question given this paragraph: Which of the following statements about mechanoreceptors is false? a. Pacini corpuscles are found in both glabrous and hairy skin. Merkel's disks are abundant on the fingertips and lips. Ruffini endings are encapsulated mechanoreceptors. Meissner's corpuscles extend into the lower dermis. Meissner's corpuscles, (shown in Figure 36.6) also known as tactile corpuscles, are found in the upper dermis, but they project into the epidermis. They, too, are found primarily in the glabrous skin on the fingertips and eyelids. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. They are rapidly adapting, fluid-filled, encapsulated neurons with small, well-defined borders and are responsive to fine details. Like Merkel's disks, Meissner's corpuscles are not as plentiful in the palms as they are in the fingertips. Q: Meissner's corpuscles are not as plentiful in the palms as they are in the what other part of the hand? Choices: - bones - fingernails - cuticles - fingertips A:

Ans:fingertips
Answer the following question given this paragraph: Annelids are divided into many repeating segments. The earthworm in Figure below is an annelid. You can clearly see its many segments. Segmentation of annelids is highly adaptive. Each segment has its own nerve and muscle tissues. This allows the animal to move very efficiently. Some segments can also be specialized to carry out particular functions. They may have special structures on them. For example, they might have tentacles for sensing or feeding, "paddles" for swimming, or suckers for clinging to surfaces. Q: What distinguishing characteristic of annelid anatomy shows specialization and adaptation? Choices: - asymmetry - beautiful - compression - segmentation A:
segmentation
