What is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?
Art [367]

CORRECT ANSWER:

a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.

STEP-BY-STEP EXPLANATION:

The complete question from book is

According to Figure 9.6, what is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?

a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.

b- Signaling molecules that bind to cell-surface receptors lead to cellular responses restricted to the cytoplasm; signaling molecules that bind to intracellular receptors lead to cellular responses restricted to the nucleus.

c- Cell-surface receptors bind to specific signaling molecules; intracellular receptors bind any signaling molecule.

d- Cell-surface receptors typically bind to signaling molecules that are smaller than those bound by intracellular receptors.

e- None of the other answer options is correct.

Joe leans against a lamp-post with a force of 200 N. The lamp-post does not move. How much work is done by the car? Explain your
Hoochie [10]
In physics, a force is said to do work<span> if, when acting, there is a displacement of the point of application in the direction of the force. It is expressed as </span><span>Work done = force (N) X distance (m). From the problem statement, the distance traveled is zero. Therefore, the work done is zero as well.</span>

If a person walks first 70 m in the direction 37° north of east, and then walks 82 m in the
timurjin [86]

Aster's final position from her initial position is 63 m approximately. She will head north west direction to return to her initial position

<h3>What is Displacement ?</h3>

Displacement is the distance travelled in a specific direction. It is a vector quantity.

Given that a person walks first 70 m in the direction 37° north of east, and then walks 82 m in the direction 20° south of east, and finally walks 28 m in the direction 30° west of north.

a) Let P be the Aster's final position from her initial position?

We can use bearing by using Cosine formula to solve this question.

P² = 70² + 82² - 2 × 70 × 82 cos 73

P² = 4900 + 6724 - 11480 cos 73

P² = 11624 - 3356.43

P² = 8267.57

P = √8267.57

P = 90.9 m

P = 90.9 - 28

P = 62.9 m

We can get the angle by using Sine rule

82/ sin Ф = 90.9 / sin 73

sin Ф = 0.8627

Ф = Sin^{-1} (0.8627)

Ф = 59.6°

Ф = 60°

b)  She will head north west direction to return to her initial position

1. how to find out the elecronic structure of<br> i. lithium<br> ii. potassium<br> iii. sodium
Setler [38]

Answer:

See explanation

Explanation:

To find out the electronic structure of each element, you must know the number of electrons it contains.

If you find that out(the number of electrons in the neutral atom of an element is the same as its atomic number). Then you arrange those electrons in such a way that the first shell has only two electrons and subsequent shells have eight electrons.

Look up the groups to which the elements belong in the periodic table All the elements are in group 1 so the last shell must have only one electron.
