Q: Metabolic cooperation between different prokaryotic species often occurs in surface-coating colonies. what are these colonies called? Read this paragraph and choose the correct option from the provided answers: Choices: - eukaryotes - lichens - plankton - biofilms A:
biofilms

(Question)
Q: What substances that primarily comprise plasma membranes form a bilayer? Read this paragraph and choose the correct option from the provided answers: Plasma membranes are primarily made up of phospholipids (orange). The hydrophilic ("water-loving") head and two hydrophobic ("water-hating") tails are shown. The phospholipids form a bilayer (two layers). The middle of the bilayer is an area without water. There can be water on either side of the bilayer. There are many proteins throughout the membrane. Choices: - amino acids - enzymes - steroids - phospholipids A:
(Answer)
phospholipids

Ques: Q: What bifurcates into the right and left bronchi in the lungs? Read this paragraph and choose the correct option from the provided answers: Figure 39.9 The trachea bifurcates into the right and left bronchi in the lungs. The right lung is made of three lobes and is larger. To accommodate the heart, the left lung is smaller and has only two lobes. Choices: - neck - aorta - cornea - trachea A:
Ans: trachea

(Q).
Q: Like people with type 1 diabetes, people with type 2 diabetes must frequently check what level? Read this paragraph and choose the correct option from the provided answers: Some cases of type 2 diabetes can be cured with weight loss. However, most people with the disease need to take medicine to control their blood sugar. Regular exercise and balanced eating also help, and should be a regular part of the treatment for these people. Like people with type 1 diabetes, people with type 2 diabetes must frequently check their blood sugar. Choices: - glucose - pulse - heartbeat - blood sugar A:
(A).
blood sugar

Ques:Q: Since electrons are charged, their intrinsic spin creates a what? Read this paragraph and choose the correct option from the provided answers: We already know that the magnitude of angular momentum is quantized for electron orbits in atoms. The new insight is that the direction of the orbital angular momentum is also quantized. The fact that the orbital angular momentum can have only certain directions is called space quantization. Like many aspects of quantum mechanics, this quantization of direction is totally unexpected. On the macroscopic scale, orbital angular momentum, such as that of the moon around the earth, can have any magnitude and be in any direction. Detailed treatment of space quantization began to explain some complexities of atomic spectra, but certain patterns seemed to be caused by something else. As mentioned, spectral lines are actually closely spaced doublets, a characteristic called fine structure, as shown in Figure 30.53. The doublet changes when a magnetic field is applied, implying that whatever causes the doublet interacts with a magnetic field. In 1925, Sem Goudsmit and George Uhlenbeck, two Dutch physicists, successfully argued that electrons have properties analogous to a macroscopic charge spinning on its axis. Electrons, in fact, have an internal or intrinsic angular momentum called intrinsic spin S . Since electrons are charged, their intrinsic spin creates an intrinsic magnetic field. Choices: - suppressed electrical field - magnified rupulsed field - intrinsic electrical field - intrinsic magnetic field A:

Ans:intrinsic magnetic field

Ques:Q: What is caused by differences in density at the top and bottom of the ocean? Read this paragraph and choose the correct option from the provided answers: Currents also flow deep below the surface of the ocean. Deep currents are caused by differences in density at the top and bottom. More dense water takes up less space than less dense water. It has the same mass but less volume. Water that is more dense sinks. Less dense water rises. What can make water more dense?. Choices: - shallow currents - still water - flat currents - deep currents A:

Ans:
deep currents
