Answer:

No, it is a cycle, so it repeats cyclic.

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, formation of two daughter cells (mitotic phase).

Mitotic phase is subdivided into four phases:

prophase, - nuclear envelope breaks down, condensed chromosomes are released

metaphase- chromosomes are lined up, mitotic spindle is formed

anaphase - the sister chromatids of each chromosomed move to the opposite ends of the cell

telophase-final stage, nuclear envelope reforms

Give any two difference between digestive system in humans and digestive system in ruminants

Otrada [13]

Answer:

Hey mate......

Explanation:

This is ur answer.....

1. Ruminant stomachs have four compartments, and monogastric stomachs have only one compartment. Ruminants are able to digest grasses and other fibrous feeds better than animals with monogastric systems can.

 

2. The bacteria can digest fiber allowing the dairy cow to consume grass, forages, and fibrous by-product feeds that humans or monogastric animals cannot do effectively. The abomasum is the stomach compartment similar to the human stomach.

Hope it helps!

Svetllana [295]

Answer:

Check the diagram to see the answer.

Explanation:

The DNA or deoxyribonucleic acid also referred to as Double-Helix is found in the nucleus of the cell. It holds the genetic code passed from parents to offsprings during reproduction. DNA strands and proteins form a complex in the nucleus. The DNA polymerase as well as ligase and helicase help in the replication and repair of DNA strands.

The RNA is complementary to its DNA counterpart. It is synthesized from the DNA by the RNA polymerase during the process of transcription. A sequence of three DNA or RNA is called a condon, and each condon is an Amino acid or stop bit. The RNA has a single-helix shape

Motor proteins require energy in the form of ATP. ATP hydrolysis results in a conformational change that allows the protein to m

Serjik [45]

Answer:

The correct answer will be- the head globular domain of the motor protein.

Explanation:

Motor proteins are a class of proteins which can move along the cytoskeletal system of the cell using a mechano-chemical mechanism which involves conformational change, filament binding and releasing.

The kinesin and myosin are two important motor proteins which move along the actin filaments by converting the chemical energy of the ATP into motion.

The structure of motor molecules contains two globular head domains which bind ATP and ATPase enzyme break down the ATP releasing energy utilized by the motor protein to move.

Thus, the head domain of the motor protein enables movement.
