Mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. They are both preceded by one round of DNA replication. The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. The main differences between mitosis and meiosis occur in meiosis I.

ss7ja [257]

1. Answer;

-secondary structure;

Explanation;

Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction. In the beta sheet secondary structure, the polypeptide backbone is nearly fully extended. The R-groups are alternately pointed above and then below the extended backbone.

2. Answer;

- Quaternary structure

Explanation;

-Many proteins are formed from more than one polypeptide chain. The Quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits.

3. Answer;

-Tertiary structure

Explanation;

Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.

The tertiary structure is the structure at which polypeptide chains become functional. At this level, every protein has a specific three-dimensional shape and presents functional groups on its outer surface, allowing it to interact with other molecules, and giving it its unique function.

4. Answer;

Primary structure

Explanation;

-It is the simplest level of protein structure and is simply a sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B. Each chain has its own set of amino acids, assembled in a particular order. For instance, the sequence of the A chain starts with glycine at the N-terminus and ends with asparagine at the C-terminus, and is different from the sequence of the B chain.

inn [45]

when a prairie dog spots a predator, it responds by giving an alarm call, but only when close relatives are near. this is an example of vocalization.

<h3>What do you mean by predator ?</h3>

The interaction between prey and a predator, where the energy flow occur called as predation and the organism feed on other organism called as predator and the food means the other organism is called as prey.  

Predators can be carnivores and omnivores like Lions, tigers, sharks, and snakes, all are predators, it can fall prey to other large animals E.g. a snake is a predator to a mouse, but prey to a hawk.

Carnivorous predators directly kill and eat their prey like large animals such as the lion and tiger, they have their own mode of feeding.

Herbivore are plant eating animals like cows, buffaloes, goats, sheep, and deer; parasites are also under the category of predators which is a host dependent and live, get nutrients from host's body for survival and reproduction.

Which statement describe what happens with ATP during glycolysis
Delvig [45]

The first stage of cellular respiration is glycolysis. It does not require oxygen. During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.
