You learn that a Mars lander has retrieved a bacterial sample from the polar ice caps. You obtain a sample of this bacteria and

perform the same kind of experiment that Meselson and Stahl did to determine how the Mars bacteria replicates its DNA. Based on the following equilibrium centrifugation results, what type of replication would you propose for this new bacteria?

Answer:

The list of options to complete the question are

a. conservative replication

b. semi conservative replication.

c. dispersive replication

d. discontinuous replication

e. continuous replication

THE ANSWER IS C.

c. dispersive replication

Explanation:

In this type of DNA replication, the original DNA chain is broken down and combined randomly before the

unwinding of the double helix structure and separation to form a template for synthesis of messenger RNA

Found in retina, Starbust amacrine cells are characterized by simultaneous release of two neurotransmitters. These two neurotransmitters are GABA and acetylcholine. Bistratified states dual layer of cells. So, bistratified starburst amacrine cells occur in two types namely ON and OFF types.

ON  types has stomata in Ganglion cell layer Inner Plexiform Layer while OFF types has stomata in Inner Nuclear Layer and Inner Plexiform Layer. Sox2 is a transcription factor associated with ability to modify the morphology and ratio of cells.

The mentioned paper aims to find if both ON and OFF types are neurally connected by bistratified starburst amacrine cells. The results suggested that Sox2 can alter binding of bipolar cells with dendrites.

The_ of an element tells how many particles are in the nucleus of each atom.
Ugo [173]

<u>Answer:</u> The mass number of an element tells us about the number of particles present in the nucleus of an atom

<u>Explanation:</u>

Nucleons are defined as the sub-atomic particles which are present in the nucleus of an atom. Nucleons are protons and neutrons.

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

<u>For Example:</u>  Taking an isotope of chlorine, Cl-35

Atomic number = Number of protons = 17

Mass number = Nucleons = 35

Hence, the mass number of an element tells us about the number of particles present in the nucleus of an atom

antiseptic1488 [7]

Answer:

The answer is "Option c".

Explanation:

Throughout the given question, Option c is acceptable which is based on the graph. The status of parts BC and DE are significantly changed because the temperature in the parts BC (0 degrees Celcius) & DE (100 degrees Celcius) is relatively stable to only the template would also have changed from ice and water into the vapor.
