ddd [48]4 years ago
3 0

Answer:

Carbon based molecules have 3 main structures which are

straight chain

branched chains

rings

Explanation:

The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.

Describe how protists are helpful and harmful to humans and other organisms
-BARSIC- [3]

Answer:

Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live.  For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

Sorry but I am bad at biology
Nimfa-mama [501]

We have 600 grams of grass, which has 450 grams of water. This means that there are 600 - 450 = 150 grams of dry weight (aka dry grass without any water)

20% of the dry weight is the amount of protein the rabbit gets

20% of dry weight = 20% of 150 = (20/100)*150 = 0.20*150 = 30

<h3>Answer: The rabbit eats 30 grams of protein per day</h3>
