Nucleotides, which are the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a _____________________. Lipid 5-carbon sugar Starch

Answers

Answer;

-5-carbon sugar

Explanation;

-The basic repeating unit of nucleic acids are known as nucleotides. There are two types of nucleic acids, namely RNA and DNA.

-A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.


Final answer:

Nucleotides consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar.

Explanation:

Nucleotides, the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar. The 5-carbon sugar is called a pentose sugar. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, it is ribose.

In which of the following states can water Not exist? A. liquid B. gas C. solid D. none of the above

Answers

Water exists in all the statesofmatter which are the solid, liquid, and gaseous states.

What are the states of water?

Water is known to exist in three different physicalstates. These are the solid state as ice, the liquid state as water itself, and the gaseous state as water vapors.

Under the conditions of standard temperature and pressure, the freezing point of water is zero degrees Celsius. At this temperature, water starts to freeze and attains a solid form which is in the form of ice. The density of ice is lower than the density of water because of the fixed intermolecular distances in ice.

Under the conditions of standard pressure and temperature, water exists in liquid form between temperature ranges of zero to a hundred degrees Celsius. Liquidwater is essential for all organisms. It functions as a universal solvent.

At a temperature above hundred degrees Celsius, the intermolecular integrity between the molecules of water starts to decrease and ultimately breaks completely. In these conditions, the water turns into vapors.

Therefore, water exists in all the states of matter which are solid, liquid, and gaseous states.

Complete the sentence with the correct information. One of the big advantages to a 401(k) plan is that ______.a. 401(k) plans are rare enough that they are very valuable
b. the plan automatically increases in value by 500%
c. you don’t have to pay into a 401(k) with your own money
d. the amount you contribute reduces your taxable income

Answers

d. the amount you contribute reduces your taxable income

A 401(k) is a retirement savings plan sponsored by an employer. It lets workers save and invest a piece of their paycheck before taxes are taken out. Taxes aren't paid until the money is withdrawn from the account.

One of the big advantages to a 401(k) plan is that the amount you contribute reduces your taxable income. The correct answer is (d).

A plan is a detailed proposal for achieving a specific goal or objective. It typically involves outlining a series of steps or actions that need to be taken in order to achieve the desired outcome.

One of the big advantages to a 401(k) plan is that the amount you contribute reduces your taxable income.

  • This means that the money you put into your 401(k) is deducted from your taxable income, which can lower the amount of income tax you owe.
  • Additionally, many employers offer matching contributions to employees' 401(k) plans, which can help to grow your retirement savings even faster.
  • In general, 401(k) plans are a popular way for people to save for retirement because they offer a tax-advantaged way to invest in the stock market or other investment vehicles.

Therefore, the correct answer is option d. the amount you contribute reduces your taxable income.
