Answer:
Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus
Explanation:
Organelles are membrane bound only in eukaryotic ccells.
Prokaryotic cells unlike eukaryotic cells, do not have membrane bound organlles.
Something that is found in both prokaryotic and eukaryotic cells is the cytoplasm, which is fluid that is inside the whole cell.
Unlike eukaryotic cells, prokaryotic cells have loose DNA, which floats around the cell quite literally.
The only way DNA is stored in eukaroyotic cells is in the nucelus, which is only found in eukaryotic cells, not prokaryotic.
Hope this helps ;)

Describe the conversion of light energy in a blackberry plant.
Answers
Answer:
Anthocyanins are used in organic solar cells because of their strong light harvesting, and their ability to convert this light energy into electrical energy.
Explanation:
Solar panels plug you into the sun by absorbing solar energy with photovoltaic (PV) cells. When hit with sunlight, they generate electricity which then flows into a device called an inverter which converts the electricity into a form (120 volts, 60Hz) for household use.
What is the molarity of a solution made from dissolving 10.0 moles of NaOH into 5.0
liters of solution?
A. 1.0 M
B. 1.5 M
C. 5 M
D. 2 M
Answers
Answer:
Option D
Explanation:
Molarity (M) of any solution is equal to the number of moles (n)of solute in it divided by total volume of solution (V)
Mathematically, it can be represented as
[tex]M = \frac{n}{V}[/tex]
Substituting the given values, we get-
[tex]M = \frac{10}{5} = 2[/tex]
Hence, option D is correct
Calculate the pH of the solution, given the following (H+). Then identify the
solution as acidic, basic, or neutral. [H+]=7.94x10^-5 *
4.1; basic
0 6.9; basic
04.1; acidic
Answers
Answer: 4.1 Acidic
Explanation:
pH = -log(H+)
= -log (7.94x10^-5)
= 4.10017949757
= 4.1
any pH under 7 is acidic
Using the reaction: Mg + O2 --> Mgo,
What is the balanced equation?
If you start with 2g Mg, how many grams of
02 do you need for this reaction to go to
completion?
Answers
Answer:
2Mg +O2 -----》 2MgO
the balanced equation
if you start with 2g of Mg let's calculate moles
one mole of mg id 24.30 g
so number of moles =0.08
hence 2 moles of Mg reacts with 1 mole of O2 molecule
so Moles of O2 molecule is 0.04
and mass of O2 in gm is = 16 ×0.04
which is equal to 0.64 gm
so the conclusion is if you start with 2g Mg, you need 0.64 grams of
O2 molecules for this reaction to go to
completion!!

Early historical models of the solar system were geocentric. Which of these phrases describes a geocentric solar system?
A. the sun as a reference point
B. existing in a star system
C. Earth as a reference point
D. circular, orbital path of travel
Answers
The accurate description of a geocentric solar system is the earth as a reference point.
The solar system refers to the arrangement of the sun and the planets. The description of the solar system in which the earth constitutes the center or reference point is called the geocentric model.
An alternative and more accurate model devised by Copernicus is the heliocentric model in which the sun lies at the center of the solar system.

What are the half-reactions for a galvanic cell with aluminum and gold electrodes?
A. A3+ (aq) + 3e > Al(s) and Au+(aq) + e* → Au(s)
B. Al(s) → A13+(aq) + 3e and Aut(aq) + e
Au(s)
C. AB+(aq) + 3e – Al(s) and Au(s) — Au (aq) + e
D. Al(s) → AB+(aq) + 3e and Au(s) → Au(aq) + e
Answers
Answer:B is right
Explanation: Al loses electrons and is oxidised, Au gains electron. And is reduced
To solve such this we must know the concept of half cell reaction. Therefore, the correct option is option B that is Al(s) → A1³⁺(aq) + 3e and Au(aq) + e [tex]\rightarrow[/tex]Au(s)
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Oxidation is loss of electrons and reduction is gain of electrons. The electron transfer from oxidant to reductant. Al loses electrons and is oxidized, Au gains electron. And is reduced.
Therefore, the correct option is option B that is Al(s) → A1³⁺(aq) + 3e and Au(aq) + e [tex]\rightarrow[/tex]Au(s)
