Group of organs that work together to carry out a specific function - > Organ system
Glycans are a virulence factor for which group of organisms?
A. fungi
B. viruses
C. bacteria
D. protozoa
E. helminths
Answer:
C.bacteriaExplanation:
because bacterial glycans are attractive pathogen-specific targets. Bacterial cells are coated with an impressive array of glycan structures that comprise their cell wall
Glycans are a virulence factor for bacteria. So, the correct option is C.
What are Glycans?
Glycans are also known as polysaccharides, are carbohydrate-based polymers made by all living organisms. They are basically chain-like structures that are composed of single sugar molecules (monosaccharides) linked together by chemical bonds.
Now, out of given organisms, only bacterial cell walls are mainly composed of polysaccharides. So, these glycans sites are target sites for disease-causing agents to perform their activity.
Therefore, glycans are a virulence factor for bacteria.

Which is one reason for the formation of global winds? (1 point)
-uneven heating of Earth's surface
-fewer daylight hours in Arctic regions
-loss of energy as warm air rises
-condensing of moisture in cooling air
One reason for the formation of global winds is the uneven heating of the Earth's surface.
The uneven heating of the Earth's surface is primarily caused by variations in solar radiation received at different latitudes.
The equator receives more direct sunlight when the sun's rays strike the Earth's surface, they heat the air in contact with it. n the poles, resulting in a temperature gradient across the planet. This temperature gradient drives the formation of global winds.
Fewer daylight hours in Arctic regions: This option is incorrect. The number of daylight hours in a region does not directly contribute to the formation of global winds. While sunlight does play a role in heating the Earth's surface and driving atmospheric circulation, the length of daylight hours is not a determining factor.
Loss of energy as warm air rises: This option is valid. As warm air rises due to heating from the Earth's surface, it expands and cools. This cooling causes the air to lose energy, and as a result, it becomes denser and sinks back toward the surface. This sinking motion creates regions of high pressure, which contribute to the formation of global winds.
Condensing of moisture in cooling air: This option is incorrect. The condensation of moisture in cooling air relates to the formation of clouds and precipitation, but it does not directly influence the formation of global winds.
Therefore, the uneven heating of the Earth's surface, due to variations in solar radiation, is a significant reason for the formation of global winds.

Ocelots eat the frogs, and the ocelots are eaten by parrots. The rest of the options are valid food chains, but they would not function in the area of tropics. The answer to the question is option B.
Which things need to be present for natural selection to take place? (select all that apply)
A.Variation in the population.
B.The ability for asexual reproduction.
C. Competition between organisms.
D. Large amounts of resources.
Answer:
A & C
Explanation:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
YES - A) You must have variation in the population, typically in the terms of "fitness" or having admirable/sucessful traits that make them more likely to reproduce and ensure their own offspring are fit too.
NO - B) It is sexual (not asexual) reproduction that uses natural selection for their offspring. Although some asexual organisms use natural selection, it is ALWAYS used if possible with natural selection to ensure the fitness of characteristics is passed down.
YES - C) Competition is necessary for natural selection to occur. When those who are more physically fit compete, they are more likely to live against their opponent and therefore pass on the trait of fitness.
NO - D) Although resources are necessary, large amounts are not as it does not lead to fighting over them (scarcity) bringing us back to the need for competition above.
