Answer: The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to pass easily down this gradient due to the alveoli having very thin walls (one cell thick).
or
The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick)
Hope this helps......... Stay safe and have a Merry Christmas!!!!!!!!!!! :D

The life cycles is typical for most fungi and some protists (B) II only. The correct option is (B).
- Most fungi and some protists (unicellular eukaryotes) have a haploid dominant life cycle, meaning that the organism's body, or mature, ecologically relevant form, is haploid.
- Fungi typically reproduce sexually as well as asexually. Mitospores are produced by the asexual cycle, while meiospores are produced by the sexual cycle. Fungi's life cycle can take many distinct forms. Fungi are thought to have a four-stage life cycle for the majority of moulds found indoors: spore, germ, hypha, and mature mycelium.
- Protists life cycles can be quite basic, involving simply periodic binary fissions, or very complex, involving asexual and sexual phases, encystment and excystment, and, in the case of many symbiotic and parasitic forms, host alternation.

Answer:
Sandy soil or Coarsely Textured Soils
Explanation:
All soils that have high amount of sand (sandy soil) or the one which have coarse texture are poor in organic matter retention and thus have low organic matter content. These soils are highly permeable and thus are unable to hold soil moisture and organic matter.
On the other hand they have rich salt content because they are in touch with salty water of sea or oceans.
