Answer 1
Answer:

Answer:

Protein synthesis, RNA sequestration, RNA transport and  to control transcriptional gene.

Explanation:

The role of non-coding RNAs in transcriptional regulation as well as proteins synthesis etc. Non-coding RNAs is responsible for controlling different processes like protein synthesis, RNA sequestration, RNA transport and  to control transcriptional gene through epigenetic regulation and chromatin remodeling. By interacting with DNA, RNA and proteins, non-coding RNAs can regulate chromatin structure and function and the transcription of neighboring.

Minos, king of Crete, had made war upon Athens. He had come with a great fleet of ships and an army, and had burned the merchant vessels in the harbor, and had overrun all the country and the coast even to Megara, which lies to the west. He had laid waste the fields and gardens round about Athens, had pitched his camp close to the walls, and had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town. Then Aegeus, the king of Athens, with the twelve elders who were his helpers, went out to see King Minos and to treat with him.–“The Cruel Tribute,”James BaldwinWhich detail from the passage creates the most suspense for the reader?“Minos, king of Crete, had made war upon Athens.”“He had laid waste the fields and gardens round about Athens.”“Then Aegeus, the king of Athens . . . went out to see King Minos and to treat with him.”

At time 0s, a population has 2 members. At time 2s, there are 4 members. At time 6s, there are 16 members. What type of growth is being experienced by this population?

Answers

Exponential growth is seen

Given that initial population, at time 0 members =2

i.e. P0 =2

P(2) = 4

In 2 minutes it became 4 times

And in 6 minutes it became 16 members

P(0) =2

P(2) =4

P(6) =16

i.e. every 2 minutes the population doubles

Hence exponential growth of population doubling in 2 minutes

P(t) = 2^{\frac{t}2}

will be the function representing the population at time t.

Exponential Growth....members are increasing to its double value within every 2s.

Which of the following is the best definition for a macromolecules

Answers

The best definition for a macromolecules is the most abundant elements found in living cells. The correct option is d.

What are macromolecules?

A macromolecule, such as a protein or nucleicacid, is a very large molecule that is important in biophysical processes.

It is made up of thousands of atoms that are covalentlybonded. Many macromolecules are polymers composed of smaller molecules known as monomers.

Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.

Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.

Macromolecules are made up of monomers, which are single units joined together by covalent bonds to form larger polymers. The most abundant elements found in living cells are the best definition for macromolecules.

Thus, the correct option is d.

Your question seems incomplete, the missing options are:

a. a trace element

b. a vitamin

c. an organic molecule necessary for life

d. the most abundant elements found in living cells

Answer:

There are no answers to choose from.

Explanation:

However, the prefix macro- means big, so the word macromolecule means large molecule. Macromolecules are also known as the molecules of life, they all contain carbon. The four macromolecules are carbohydrates, proteins, lipids, and nucleic acid. Carbohydrates are used as a quick energy source, they can be broken up into monosaccharides, dsaccharides, and polysaccharides. Proteins are used as catalyst to help speed up chemical reactions. Lipids are also known as fats, they can either be saturated or unsaturated. Nucleic acids contain information.

Examples of each:

Carbohydrate- Gluten

Protein- Lactase

Lipid- butter, or oil

Nucleic Acid- DNA or RNA
