Describe the relationship between organic compounds, nucleotides, RNA, and a universal genetic code.
makkiz [27]

Answer:

Organic compounds→ nucleotides→ RNA→ universal code.

Organic compounds are the compounds made by living organisms with at least one molecule of carbon linked to different elements like hydrogen, oxygen, or nitrogen.for example: nucleotides.

A nucleotide is the monomer units of nucleic acids- DNA and RNA. Each nucleotide is made up of organic compounds- sugar, a phosphate molecule and nitrogenous bases (adenine, guanine, cytosine, thymine and uracil).  

The arrangement of nitrogenous bases in DNA decides the fate of proteins as the sequence of these bases acts as code arranged in the triplet called "codons" which code for specific amino acids.

Thus, Organic compounds→ nucleotides→ RNA→ universal code is the correct answer.

Select all that are true of capillaries.Continuous capillaries are the most common type. Sinusoidal endothelial cells form a con
timofeeve [1]
The correct answers are a, c, d.
There are three types of capillaries: continuous, sinusoidal (or discontinuous) and fenestrated. Continuous capillaries are the most common type and they form tight junctions. Sinusoidal capillaries form an incomplete lining with several gaps, which allow red and white blood cells and some serum proteins to pass. These capillaries are mainly found in the bone marrow, lymph nodes and adrenal glands. Finally, fenestrated capillaries facilitate the movement of smaller molecules and plasma proteins and are mainly found in the small intestine. The majority of the fluid transport happens through the fenestrated capillaries.

grin007 [14]

Answer:

A. a lamp being turned on

B. a toaster being used to toast bread

D. a car horn honking

Explanation:

Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.

From the examples given in this question, the following are examples of scenarios that involve energy transformation:

- A lamp being turned on: This converts chemical energy to light energy.

- A toaster being used to toast bread: This converts electrical energy to heat energy.

- A car horn honking: This converts electrical energy to sound energy.

Note that, melting of a chocolate does not transform any form of energy.
