Lysosomes

Explanation:

Lysosome are among the organelles in a eukaryotic cell. Lysosomes are formed by the golgi bodies or the golgi apparatus.
The role of lysosomes is to digest and destroy old and worn out organelles together with cellular wastes. In other words Lysosomes break down food molecules, waste products, and old worn out cells or organelles.
They contain powerful lytic enzymes and and acids which help in the digestion and recycling of cellular materials.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to

Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ $RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-(-2))^2+(4-4)^2}$

⇒ $=\sqrt{(3+2)^2+(0)^2}$

⇒ $=\sqrt{25}$

⇒ $=5 \ units$

and,

⇒ $ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-3)^2+(-1-4)^2}$

⇒ $=\sqrt{0+(-5)^2}$

⇒ $=5 \ units$

Now,

The total trail length will be:

= $RS+ST$

= $5+5$

= $10 \ units$

Which hormone uses a second messenger mechanism? testosterone estrogen norepinephrine cortisol none of these choices?

jeka94

Norepinephrine uses the Second Messenger System, which means, cells signal to each other what molecules have been released that will trigger a physiological reaction.

This phenomenon is activated after the ligand (ion or molecule) is bonded to its receptor (protein molecule), creating a variation that causes a chain-reaction, that will finally activate the Second Messenger. The latter will activate intercellular molecules that will be able to control the cell’s activity.
