You could check if their cells had a nucleus or not. If it did it would be a eukaryote, if it did not then it would be a prokaryote.

Defined as pre-nucleus, prokaryotes are cells that contain no membrane-based organelles, including a nucleus.

Mostly recognized as bacteria, two prokaryotic kingdoms exist: Monera or Bacteria and Archaea.

Seemingly simple in structure and markedly different from eukaryotic and protist organisms, many scientists believe prokaryotic cells were amongst the first on the Earth and very well may out-survive all other organisms.

What causes the high luster of a metal?
Karo-lina-s [1.5K]

Answer:

When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals.

identify the reagents necessary to achieve each of the following transformations o3 dms, pcc, ch2cl, h2so4,h2o,hgso4
hoa [83]

the reagents necessary to convert alcohol to ketoneNa_2Cr_2O_7 , H_2O which involves oxidation of alcohols.

<h3>What is oxidation of alcohols?</h3>
  • Alcohol oxidation is a significant organic chemistry process. Secondary alcohols can be oxidized to produce ketones, while primary alcohols can be oxidized to produce aldehydes and carboxylic acids.
  • In contrast, tertiary alcohols cannot be oxidized without the C-C bonds in the molecule being broken.
  • In order to cause primary alcohols to oxidize into aldehydes
  1. Cr_2O_7 ^-^2 (dichromate)
  2. CrO_3/pyridine (Collins reagent)
  3. Chromium pyridinium compound (PCC)
  4. Dichromate of pyridinium (PDC, Cornforth reagent)
  5. Periodinane by Dess-Martin
  6. Oxalyl chloride with dimethylsulfoxide (DMSO) for Swern

What is the total pressure of a gas mixture containing partial pressures of
Advocard [28]

Answer:

1.54 atm

Explanation:

By Dalton's Law Of partial pressure,

Total Pressure = Sum of all partial pressures

So,P= P1 + P2 + P3

Therefore, P=0.23+0.42+0.89

=1.54 atm

A sample of gas has a volume of 1.20 L at standard conditions. Find its volume at 35.0 oC and 900 torr. (R = 62.4 L torr/K *mol)
timurjin [86]

Answer:

Option A. 1.14L

Explanation:

Data obtained from the question include:

V1 = 1.20 L

P1 = at stp = 760torr

T1 = at stp = 273K

P2 = 900torr

T2 = 35°C = 35 + 273 = 308K

V2 =?

Using P1V1/T1 = P2V2/T2, we can obtain the new volume as follows:

P1V1/T1 = P2V2/T2

(760 x 1.2)/273 = (900 x V2) /308

Cross multiply to express in linear form

273 x 900 x V2 = 760 x 1.2 x 308

Divide both side by 273 x 900

V2 = (760 x 1.2 x 308) /(273 x 900)

V2 = 1.14L
