A i believe is the answer
Answer:
The maximum wavelength of light for which a carbon-hydrogen single bond could be broken by absorbing a single photon = 290 nm
Explanation:
So to break a single C - H bond require =
= 6.84 x 10⁻¹⁹ joule
Find the wavelength of a photon we use E = hν
⇒ E =
Where h = Planck's constant = 6.626 x 10⁻³⁴ J.K⁻¹.Mole⁻¹
c = speed of light = 3 x 10⁸ m/sec
Wavelength =
= 2.9 x 10⁻⁷ m
= 290 nm
∵ 1 nm = 10⁻⁹ m
Answer:
Option A) Na
Explanation:
From the options given above, sodium (Na) is most likely to lose electron to form ion
Na is a group 1 metal. Metals form ions by losing electron(s).
From the options given above, only Na is a metal and so it is most likely to form ion by losing electron
The scientist is using gel electrophoresis. Gel electrophoresis is a process used to cut DNA into fragments in order to see them.
Answer:
A major function of the Endomembrane system is
The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.
Explanation:
The endomembrane system (endo = “within”) is a group of membranes and organelles (Figure 4.4. 1) in eukaryotic cells that works together to modify, package, and transport lipids and proteins. The endomembrane system is a series of compartments that work together to package, label, and ship proteins and molecules. In your cells, the endomembrane system is made up of both the endoplasmic reticulum and the Golgi apparatus. These compartments are folds of membranes that form tubes and sacs in your cells.
Hoped this helped! :D
