Answer:

A histone modification mechanism proliferate through a process that includes post translational modification procedure. The methylation, acetylation as well as ubiquitylation are one of the main modifiers that help in activation of silent genes and ultimately these covalently bonded histone modifiers help in regulating chromatin. The PTM has a main role in altering histone structure by these modifier's recruitment....

The diagram is not given in the question, so the diagram is attached below.

Answer:

chloroplast, thylakoid  space

Explanation:

The photosynthesis process is categorized in two steps light-dependent reactions and light-independent reactions.

In light-dependent reaction, chlorophyll absorbs one photon and loses one electron. This initiates the flow of electrons down an electron transport chain and result into reduction of NADP to NADPH.

Along with this, it creates a proton gradient or concentration across the chloroplast membrane and into the thylakoid  space. The proton concentration or energy gradient is then used by ATP synthase for the synthesis of ATP and cellular respiration.

Hence, the correct answer is chloroplast and thylakoid  space

Bacteria may be killed during cooking, but may leave behind ______ that will later grow and produce more bacteria.
Aliun [14]
The answer is SPORES.

Some bacteria, take for example clostridium can be killed with heat but still leave their spores.

They are heat-resistant spores that may survive cooking and later grow and produce large numbers of cells if the storage temperature is appropriate for their growth.

This image shows the various forces acting on a block of rock situated on a rock slope. What does arrow 4 represent?
AlladinOne [14]

Answer:

4 is gravitational force

Option B

Explanation:

This is a force diagram of a block on an inclined plane.

The force component is what makes up weight in the diagram. Weight is given as mass multiplied by the gravity.

Gravitational force acts downward and it is the force of attraction between all objects and the earth. It is directly proportional to mass.

Force 1 and 2 are both shear forces that acts parallel to the face of the incline. They are mostly expressed as frictional forces.

MariettaO [177]

Answer:

This is an example of replication.

Explanation:

Getting a similar outcome when a trial is rehashed is called replication. Replication is significant in science so researchers can check their work. The consequence of an examination isn't probably going to be very much acknowledged except if the examination is rehashed ordinarily and a similar outcome is constantly acquired.

Hence, This is an example of replication.
