aerosols are compressed gases and hydrocarbons, such as nitrous oxide, as propellants. the aerosols are green house gases, that contributes to the heating of the surface of the earth. this is why global warming is one of the greatest environmental problem to date

Which of the following elements would be likely to form an anion?

Vsevolod [243]

B because chlorine is a halogen. This means that it already 7 valence electrons and only needs 1 more to have a complete outer shell.

The energy in eV for light with a wavelength of 6250 angstroms is _. Note - there are 1.6 x 10-12 erg in 1 eV.

vivado [14]

Answer:

2 eV

Explanation:

The energy of a photon of light is given by the formula

$E=\frac{hc}{\lambda}$

where

h is the Planck constant

c is the speed of light

$\lambda$ is the wavelength of the photon

In this problem we have:

$h=6.63\cdot 10^{-34} Js$

$c=3.0\cdot 10^8 m/s$

$\lambda=6250 A = 6250\cdot 10^{-10} m$ is the wavelength of the photon

Therefore, the energy in Joules is

$E=\frac{(6.63\cdot 10^{-34})(3.0\cdot 10^8)}{6250\cdot 10^{-10}}=3.2\cdot 10^{-19}J$

We want to convert this energy into electronvolts: we know that the conversion factor is

$1 eV = 1.6\cdot 10^{-19}J$

Therefore,

$E=\frac{3.2\cdot 10^{-19}}{1.6\cdot 10^{-19}}=2 eV$

If the cell could no longer produce ATP, what would be the effect on the sarcoplasmic reticulum? If the cell could no longer pro

navik [9.2K]

Answer:

A. The muscle would not contract.

Explanation:

The sarcoplasmic reticulum is a specialized smooth endoplasmic reticulum that transmits electrical impulses and is the primary regulator of calcium storage, release, and reuptake. On the other hand, glycolysis and the mitochondria are responsible for cellular ATP production.

In the muscle, the SR and mitochondrial function are interconnected, ATP is used to lower myoplasmic calcium levels during muscle relaxation, this means that muscle contractility is linked to the control of sarcomeric Ca2+ delivery/removal and ATP generation/utilization. If we have a failure to remove Ca2+ from the cytosol by not producing ATP, the muscle will be prevented from relaxation, subsequently there will be a decrease in muscle contraction too.

I hope you find this information useful and interesting! Good luck!
