The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes

carry genes on extrachromosomal pieces of circular DNA called ____________ .
Biology
1 answer:
Varvara68 [4.7K]3 years ago
7 0

Answer:

1. Nucleoid

2. Plasmid

Explanation:

Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.

However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.

How can you increase kinetic energy?|
Darya [45]

                                        <u>Answer and Explanation</u>

<u>__________________________________________________________</u>

According to <em>Sciencing,</em>

<h2><em>Translational Kinetic Energy </em></h2>

<em>Translational kinetic energy is the energy of motion in a straight direction -- think of it as the energy of a car driving down the street. Kinetic energy is a function of the object's mass and its velocity. More specifically, translational kinetic energy can be described as one-half times the mass times the square of the object's velocity: 1/2mv^2. </em>

<em> __________________________________________________________</em>

<h2><em>Increasing Translational Kinetic Energy </em></h2>

<em>Because the translational kinetic energy formula consists of only two variables, mass, and velocity, increasing one of those properties is the only way to increase an object's translational kinetic energy. Increases to mass and velocity, however, do not have the same impact. Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity. </em>

<em> __________________________________________________________</em>

<h2><em>Rotational Kinetic Energy </em></h2>

<em>Rotational kinetic energy describes the energy of an object rotating around a center of gravity -- for example, a rider on a Ferris wheel. In this case, kinetic energy is still a function of mass and velocity, but the terms used are slightly different to account for the movement in a circular direction. Rotational kinetic energy applies the same equation, except the mass term is replaced by a variable known as the "moment of inertia," (I), while the velocity term is replaced by the object's "angular velocity," (w) -- 1/2Iw^2. </em>

<em> __________________________________________________________</em>

<h2><em>Increasing Rotational Kinetic Energy </em></h2>

<em>As with translational kinetic energy, increasing energy is a matter of increasing mass and velocity. The "moment of inertia" is equal to an object's mass times the square of its distance from the center of rotation, so it can be increased by either increasing the object's mass or moving it farther from the center of rotation -- simply build a bigger Ferris wheel. Alternatively, you can increase the kinetic energy by increasing the angular velocity, which means simply increasing the speed at which the object rotates around the center of rotation.</em>

How does the ribosome know how to make the protein.?
alexdok [17]
According to google

So the ribosome moves along way and many tRNA molecule transport the correct amino acid to make the correct sequence which is to be formed and only stops when mRNA shows 'STOP' codon. So there is a chain of polypeptide which is synthesised by copying the DNA and this is how proteins are made.

and for clarification t-RNA is transfer RNA and m-RNA is messenger RNA

The main function of the inflammatory response is 1.to initiate the production of antibodies. 2.remove contaminating microorgani
masya89 [10]

Answer:

3.initiate repair of damaged tissues.

Explanation:

Inflammation is a process or response that occurs when the immune cells produce substances in order to protect the body from injuries infection by foreign microbes like viruses and bacteria. The main functions of inflammation or inflammatory response are to remove the cause of injuries in cell, get rid of damaged tissues and necrotic cells that might have been damaged during injury and initiate the repair of damaged tissues.

During inflammatory response certain symptoms like redness, heat/warmth, swelling and pain are most likely to be experienced.
