Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.

1Which waste needs to be sorted and which can be disposed of in the general bin? 2How do you know which wastes can be recycled and sorted? 3Provide arguments to show that we save energy by making items from recycled materials.
Answer:
Waste which needs to be sorted are: Plastic, paper, and alminium. And the ones can be disposed can be any other items such as food, sweet wrappers, plastic wrapping, and broken glass.
The waste bags are opened and the waste is put onto a conveyor belt and moved into a processing area. First, the waste will go into a pre-sort area, where any items that can't be recycled are removed, and then the materials move into an area where they can be sorted automatically by machines, or manually by workers.
As most people know, recycling can reduce pollution, animal harm, and energy because we won't need as much material to be making the same thing over and over again so in general, recycling is the best way to save energy and for the sake of the planets environment.

Manish is growing crop of Bengal gram and he did not add any nitrogen fertilizers to the soil. Would he get a better yield? How would the plants cope up with their nitrogen requirements?
Answer: Bengal gram is a leguminous plant.
Explanation:
Legumes are the plants that can fix nitrogen by symbiotic mutualistic association with the soil bacteria. The bacteria converts atmospheric nitrogen into plant usable for like ammonia and derives nutrition from the plant in return. This association results in the formation of root nodule for uptake of nitrogen derivatives from the soil and return of nutrients to bacteria. Bengal gram is a leguminous plant so it can avail nitrogen with symbiotic association with the bacteria in the soil. Although nitrogen is not given in the fertilizer but the gram crops can sustain themselves by obtaining nitrogen from the soil in association with nitrogen fixing bacteria.

Which of the following describes a scenario that would result in the phenotypic change shown in the graph?
A) A fish that has mouth parts adapted to eat moderately sized prey is introduced into a lake in which there are only large and small prey.
B) A population of mice live on the ground and in short trees. An invasive, tree-dwelling snake that preys on the mice is introduced into the area.
C) Climate change-induced warming of arctic tundra reduces average snow cover that lighter-colored arctic
foxes rely on for camouflage. Darker-colored arctic foxes are better suited to the exposed moss and grass habitat.
D) House sparrows that lay smaller-than-average clutches of eggs produce fewer viable offspring, while larger-than-average clutches of eggs result in malnourished chicks that have a higher mortality.
Answer:
C) Climate change-induced warming of arctic tundra reduces average snow cover that lighter-colored arctic foxes rely on for camouflage. Darker-colored arctic foxes are better suited to the exposed moss and grass habitat.
The graph shows how 'climate change reduces snow cover that lighter-colored arctic foxes rely on for camouflage, whereas darker arctic foxes are better suited'.
What is adaptation?Adaptation refers to the emergence of phenotypic characteristics to face environmental factors.
Adaptations are evolutionary responses to challenging environmental conditions.Adaptations are fundamental during environmental change (e.g., (climate change).In conclusion, the graph shows how 'climate change reduces snow cover that lighter-colored arctic foxes rely on for camouflage, whereas darker arctic foxes are better suited'.
