Almost all amino acids are chiral. The body only uses L amino acids, and proteins are chains of amino acids that in the most sim

ple sense fold up into a single structure by themselves when they are formed. Do you think a cell could live with all D (the opposite of L) amino acids, explain your logic. When I ask 'live', I mean could the organism/cell be composed completely of D amino acids and live (This is just a thought question, don't bother trying to find the answer anywhere…)

Answer:

An organism that is completely composed D amino acids cannot survive.

Explanation:

Most of amino acids in all organism are present in L conformation.As result  in all organism the enzymes are specific for L amino acids but not for D amino acids.

   Bacterial cell wall contain some D amino acids such as D glutamate,D alanine but not entirely composed of D amino acids.

Complete the following table for the three key subatomic particles.
ASHA 777 [7]

Answer:

This question is incomplete without the table

Explanation:

The missing table is attached to this answer.

There are three subatomic particles found in an atom; protons, neutrons and electrons. The properties of the subatomic particles will be classified under the following subheadings (which are the empty columns/boxes in the attachment)

SYMBOL

The symbol of proton is "p⁺", the symbol of neutron is "n⁰" and the symbol of electron is "e⁻".

CHARGE

Looking at the symbol of the subatomic particles, one can guess the charge of each of the particles from the superscript.

Protons are positively charged, electrons are negatively charged while neutrons have no charge/electrically neutral.

The relative charge of proton is +1 while it's absolute charge is +1.60218 × 10⁻¹⁹

The charge of a proton was first determined by Ernest Rutherford using the gold-foil experiment

The relative charge of electron is -1 while it's absolute charge is -1.60218 × 10⁻¹⁹

The charge of an electron was first determined by R. Milikan using the oil-drop experiment

The relative charge and absolute charge of neutron is 0

The charge of a neutron was first determined by (or credited to) James Chadwick.

MASS

The relative mass (amu) of proton is 1.00727 while that of neutron is 1.00866. The relative mass (amu) of an electron is 0.00054858 while it's absolute mass (g) is 9.10939 × 10⁻²⁴.

The mass of an electron was first measured by J. J. Thomson.

The mass of a proton was first measured by (or credited to) Ernest Rutherford.

The mass of a neutron was first measured by James Chadwick.

LOCATION

The protons and neutrons <u>are located inside the nucleus</u> which is found in the centre of an atom while the electron(s)<u> is/are found outside the nucleus but within the atom</u>.

1 and 2 the forces holding water molecules together are stronger than the forces holding alcohols molecules together these forces are stronger in water due to hydrogen bonding the intermolecular forces forces that hold the water together are stronger than alchol because water has hydrogen bonding hydrogen bonding is hydrogen being attracted to oxygen or flourine or chloroine the electronegativity differences are larger the forces holding the bonds are stronger its like hydrogen is holding on to oxygen strongly different types of forces are lomdon dispersion forces like helium which have low boiling point they have nothing holding them together water has hydrogen bonds alcohol doesnt have the hydrogen bonds water has and geometry vsper model polar and hydrogen bonds as water so theyre weaker.

A balloon is filled with 2.5 L of helium at 1 atm of pressure. If the pressure
ch4aika [34]

Answer:

5 L

Explanation:

Given data

  • Initial pressure (P₁): 1 atm
  • Initial volume (V₁): 2.5 L
  • Final pressure (P₂): 0.50 atm
  • Final volume (V₂): ?

For a gas, there is an inverse relationship between the pressure and the volume. Mathematically, for an ideal gas that undergoes an isothermic change, this is expressed through Boyle's law.

P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{1atm \times 2.5L}{0.50atm}= 5 L
