Answer:

They serve as chemical messengers.

Explanation:

Steroid may be defined as the molecule that are made of large number of non polar molecules and are hydrophobic in nature. The cholesterol is an important steroid present in mammals.

Steroids as a precursor for the formation of the important hormones. Steroidal hormones plays an important role in the growth and metabolism of the organisms. The sex hormone are also made of steroids. They regulate the chemical messages in the body.

Thus, the correct answer is option (b).

This procedure for measuring cell size has certain limitations . List three such limitations​
marusya05 [52]

The limitations of cell size are:

1) Surface area to volume ratio

2) Nucleo cytoplasmic ratio

3) Fragility of cell membrane

What are the cause of limitations on cell size?

The need for a surface area of sufficient area to allow the cells function→.

→If the surface area of cell increase volume increase to the cube of the linear increase.

→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.

Examples are muscle cells.

DNA _____.
Ne4ueva [31]

Answer:

Answer:

The correct answer would be "contains coded information for the creation of proteins".

DNA or deoxyribonucleic acid is a polymer of nucleotides.

It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.

In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.

The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.

It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.
