Answer:

In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.

Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.

The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)

Consider one such cell where the magnitude of the potential difference is 40 mV, and the inner surface of the membrane is at a h
GarryVolchara [31]

Answer: W = 6.4x10⁻²¹J

Explanation: <u>Work</u> is the energy transferred to or from an object due to the application of a force along a displacement.

The ion Na is gaining energy to move from a lower potential to a higher one.

For this to happen, the work done is calculated as

W=q.\Delta V

in which

W is work in Joules (J)

q is charge in Coulomb (C)

\Delta V is potential difference in Volts (V)

The ion Na has one positive charge. In coulombs, the charge is

q = 1.6x10⁻¹⁹C

The potential difference in Volts is

\Delta V = 40x10⁻³ or 4x10⁻²V

Calculating

W=q.\Delta V

W = 1.6x10⁻¹⁹. 4x10⁻²

W = 6.4 x 10⁻²¹ J

The work done to move an ion of sodium from the exterior to the interior is 6.4 x 10⁻²¹ J.

Impulses originating in the part of the brain called the medulla would most directly affect which body structure?
gtnhenbr [62]

The question is incomplete. The complete question is:

Question: Impulses originating in the part of the brain called the medulla would most directly affect which body structure?

a. A leg muscle

b. A ligament

c. An arm bone

d. The heart

Answer:

d. The heart

Explanation:

The medulla oblongata contains a number of reflex centers for regulating vital body functions such as heartbeat, breathing, and vasoconstriction. The medulla contains several nuclei, a collection of neuronal cell bodies.

For example, impulses originated in the cardiovascular center regulates the rate and force of the heartbeat and the diameter of blood vessels. Impulses from the cardiovascular center flow along sympathetic and parasympathetic neurons. An increase in sympathetic stimulation from the cardiovascular center of medulla increases heart rate and contractility while a decrease in sympathetic stimulation decreases heart rate and contractility.

The sternocleidomastoid muscles help to flex the neck. What are their antagonists
White raven [17]

Answer:

Trapezius.

Explanation:

Sternocleidomastoid muscles may be defined as one of the largest superficial cervical muscle. The main function of this muscle is the neck flexion and the head rotation.  

Trapezius muscle is the large muscle that extend from the occipital bone. The main function of the trapezius muscle is the scapula movement and support of the arm. Trapezium muscle resist the neck flexion and works as the antagonist to the trapezius muscle.

Thus, the answer is trapezius.
