To put it simply these cells are technically termed as Eukaryotic (multi-celled) and Prokaryotic (single-celled) cells.
There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. Both plant and animal cells are eukaryotic cells.

The advantage is that eukaryotic cells have a nucleus which functions formally as to store the DNA of the cell which can translate into many functions such as cell division and work structure between cells that forms the hierarchial function to tissues.

The continuation of life depends of both what and what

Masteriza [31]

The continuation of life depends on both sexual and asexual reproduction.

Reproduction is a process where an organism gives rise to another organism, often called as "offspring". Its a process of increasing the population of any species on Earth. There are two types of reproduction process-

1. Asexual- where exact copies of parent organism are formed, also only single parent is involved.

2. Sexual- Two parents of opposite sexes are involved, offsprings are not identical to parents. There is scope of variation in sexual reproduction.

Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons

kotegsom [21]

Complete question:

Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons

Amino acid sequences determine the three-dimensional structures of proteins.
Knowledge of the sequence of a protein can help to prevent mutations.
The sequence of a protein reveals much about its evolutionary history.
The sequence of a protein is necessary to determine its function.

Answer:

Knowledge of the sequence of a protein can help to prevent mutations.

Explanation:

Amino acids connect to each other by peptidic bonds to form a linear polymer. The number of amino acids composing the chain and the order in which they are arranged determines the primary structure of the protein.

The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds between the atoms that form the peptide bond.

Protein functions depend on their aminoacids sequences. The primary structure of the proteins determines the three-dimensional one. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

By knowing the sequence of amino acids, we can predict the function of the protein and we can classify them into different families. Integrants of these groups have at least 25% of their sequences identical to each other.

Also, the knowledge of the sequence allows establishing evolutionary and genetic relationships between different species.

When a mutation occurs in the sequence -an alteration in the primary structure- the protein function is modified. BUT knowing the sequence of a protein CAN NOT help to prevent mutations.

If a given element has 6 protons, what is the valence number? What is the

erastova [34]

Answer:

carbon's

For example, carbon's atomic number (Z) is 6 because it has 6 protons. The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons.

I hope it helps.

Have a great rest of your day.
