What do you call the red pigment found in vertebrates that functions in oxygen transport?

There are actually two red pigments found in certain vertebrates that function in oxygen transport (or storage). Hemoglobin is present in the blood of most vertebrates and binds oxygen molecules, in order to transport them to body tissues in need of oxygen for energy (ATP) production.
Myoglobin, mainly in mammals, is a protein (enzyme) found in red (skeletal) muscle cells, that aids in binding oxygen when it's plentiful being delivered via blood. The purpose is that in high stress, low oxygen situations such as strenuous exercise, the myoglobin releases its bound oxygen to provide it to the starving overworked muscle cells.
**Fun fact: it's the hemoglobin that gives the bright red color of blood when it's bound to oxygen, and the myoglobin of mammal flesh gives it the typical pinkish-red hue that is seen in mammalian meat (veal, steak, ham, venison, bison, etc.). Other non-mammalian animals (fish, birds, frogs, snake, alligator, etc.) tend to have lighter-colored skeletal muscle meat due to the lack of myoglobin, amongst other factors.

If the ultraviolet light damages the DNA what will be its effect on the protein synthesis? [Serious Answers pls] ​
Novay_Z [31]
Since the DNA is damaged, the RNA created from it will not be correct. So after protein synthesis the protein will come out with a messed up shape. A change in the shape means a change of the function for a protein. So, In the end, the protein would not function as intended.

How does velocity impact force how and why
olasank [31]

At impact, the force due to gravity is =

F

=

m

g

, where we see that a larger force corresponds to a larger mass. To rectify this with your intuition, as in a brick would hurt more if it landed on my head when dropped from a higher distance -- This is true (I don't recommend experiment), but the relevant quantity is

i

m

p

u

l

s

e

, which you can look up, or a more careful analysis of the acceleration of the brick when it lands on something, where we see that at contact, in a very short period of time, the velocity goes from →0

v

→

0

, so the force experienced is:

==∼ΔΔ=−0

F

=

d

p

d

t

=

m

d

v

d

t

∼

m

Δ

v

Δ

t

=

v

−

0

t

ϵ

Where we see that the faster the brick slows down (

t

ϵ

) the larger the force experienced by the brick (and equally and oppositely, your head), which I think is more in the vein of what you are asking.
