Explain how cells specialize to form specific tissue and organs?

1 answer:

5 0

<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods. The latest one uses a weak acid to stress the cells.</span>

Two equal forces F have resultant of 1.5F .Find the angle between the forces

Grace [21]

Answer:

Angle between the forces $= 82.82$ degrees

Explanation:

The resultant force value $= 1.5$ times of Force F

$|R| = |F1| = |F2| =|F|$

Where R is the resultant force

$R^2 = A^2 + B^2 + 2AB cos X\\(1.5F)^2 = F^2 + F^2 + 2F^2 cos X\\2.25F^2 = 2F^2 + 2F^2 cos X\\$

Cos X is the angle between the two forces.

On further simplifying the equation we get

$2.25F^2 = 2F^2(1 + cos X)$

$(1 + cos X) = \frac{2.25F^2}{2F^2} \\(1 + cos X) = \frac{2.25}{2} \\(1 + cos X) = 1.125\\cos X = 1.125 - 1\\Cos X = 0.125\\X = Cos^{-1}0.125\\$

$X = 82.82$ degrees

Angle between the forces $= 82.82$ degrees

What is shape does sulfur trifluoride form

aivan3 [116]

Butterfly shape - Each fluorine is attached to the sulfur by a single covalent bond. The SF3 molecule is very short-lived and its structure has not been determined experimentally. It is calculated to adopt a butterfly-shaped molecular geometry, belonging to the Cs point group.
