Answer: Option B.

Their cell walls consist of mainly cellulose

Explanation:

Fungi are group of Eukaryotic organisms that are found in almost all habitat, moist or land. They are either single celled or multicellular.

Their cell walls is made up of chitin. They are heterotrophs i.e they cannot synthesis their own food. They bodies consist of hyphae, a long filamentous structure. Some are parasitics and some are saprophytic. They are classified in their own kingdom, they are neither plants or animals.

Examples include yeasts, molds, mushrooms e.t.c.

When you drink sea water, what type of solution do you expose your cells to?

Alex Ar [27]

The answer should be 1, hypertonic.

Seawater is highly concentrated in salt, and with that being said, it has a low concentration of water molecules.

Hypertonic means the solution has a lower water concentration than the other side (cell), vice versa for hypotonic, a high water concentration than the other side of the solution, and for isotonic, it means that both sides of the solution have the same water concentration.

So, the answer should be 1, hypertonic.

In addition, when your cells are exposed to hypertonic solution, the water molecules in your cells will start flowing out of the cells, to the outside, due to the difference in water concentration leading to osmosis. Your cells will lose so much water that they may even shrink!

based on the living things in the pyramid, tell me what examples would fit into these categories: primary producers, primary con

algol [13]

Answer:

- Oak trees: primary producers

- Caterpillars: primary consumers

- Blue Jays: secondary consumers

- Hawks: tertiary consumers

Explanation:

A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen

Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3 curly tales trait carriers with no tail (shown in dark blue)

1 straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

$\frac{1}{4}$ of the offspring (genotypes tt C_ and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is $\frac{1}{2}$ curly tails, $\frac{1}{4}$ straight tales, $\frac{1}{4}$ tailless

A grassland is experiencing a severe drought. The lack of rain is causing the grass to die and the ponds and creeks to dry up.

dusya [7]

The population of fish will decrease.

The population of grazing animals will decrease.

<h3>What is drought?</h3>

A drought is a prolonged period without enough precipitation/water to support people, animals or crops.

With less water, fish and other creatures have fewer places to dwell, swim, and evade predators. In the near run, shrinking streams and lakes necessarily result in fewer fish. Drought conditions can cause water temperatures to rise, affecting cold-water species such as native trout.

The population of grazing animals would decrease as the grass is a food source and without their food source, there would be no source of staying meaning that they would result to finding new food sources through migration likely.
