Answer:

The correct answer is choice (B) the

production of proteins. Choice (A)

is incorrect because mitochondria

produce energy for the cell. Choice (C)

is incorrect because the cell membrane

controls the removal of substances

from a cell. Choice (D) is incorrect

because lysosomes break down

chemicals.

An organ or tissue may be better able to resist damage from hypoperfusion if the:_________
wlad13 [49]

An organ or tissue may be better able to resist damage from hypoperfusion if the: body's temperature is considerably less than 98.6°F (37.0°C)

<h3>What is hypoperfusion?</h3>
  • A word used to denote "a decreased amount of blood flow" is hypoperfusion. We can refer to ischemia that arises as "hypoperfusion" when there is insufficient blood flow.
  • Low blood pressure, heart failure, or blood volume loss are some of the causes of hypoperfusion. Lightheadedness, dizziness, headaches, nausea, exhaustion, and shortness of breath are typical symptoms that are made worse by being upright and made better by lying down.
  • Thromboemboli are encouraged to form by hypoperfusion. Severe occlusive lesions result in hypoperfusion, which alters the quantity and turbulence of blood flow and encourages the development of both white and red thrombi, which are the building blocks of emboli.

Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called:_______
slamgirl [31]

Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.

The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.

In the diagram, how many angles are alternate exterior angles with angle 5?
strojnjashka [21]

Answer:

One.

Explanation:

The attached figure shows the diagram of the given question.

We need to find how many angles are alternate exterior angles with angle 5?

Exterior angle = Angle that is made outside of the shape

Alternate angle = an angle opposite of a transversal line of another angle.

From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
