Mitosis is a form of asexual reproduction because it allows a single cell to divide and produce two genetically identical daughter cells. There is no exchange of genetic material, making the offspring an exact copy of the parent.
Mitosis is considered a form of asexual reproduction because it enables a single cell to divide and produce two daughter cells that are genetically identical to the parent cell. In asexual reproduction, there is no exchange of genetic material, thus ensuring that the offspring is an exact copy of the parent. This is the main reason why mitosis, with its mechanism of copying and separating chromosomes, is classified as asexual reproduction.
For instance, a bacterium reproduces by mitosis; first, it duplicates its DNA and then divides into two cells. Each of these two cells has exactly the same DNA as the parent bacterium.

Answer:
207.50°C
Explanation:
Mass of metal (M1) = 440g
Volume of water = 400mL
Initial temperature of water (T2) = 20°C
Final temperature of the mixture (T3) = 35.80°C
Specific heat capacity of the metal (C1) = 0.3850J/g°C
Specific heat capacity of water = 4.184J/g°C
Density of water = 1g/mL
Temperature of metal (T1) = ?
Heat lost by the metal = Heat gained by the water
Q = MC∇T
Q = heat energy
M = Mass
C = specific heat capacity
∇T = change in temperature
M1C1(T1 - T3) = M2C2(T3 - T2)
M2 = ?
Density = mass / volume
Mass = density * volume
Mass = 1g/mL * 400mL
Mass = 400g
M1C1(T1 - T3) = M2C2(T3 - T2)
400 * 0.3850 (T1 - 35.80) = 400 * 4.184 * (35.80 - 20)
154(T1 - 35.80) = 1673.6 * (15.8)
154T1 - 5513.2 = 26442.88
154T1 = 26442.88 + 5513.2
154T1 = 31956.08
T1 = 31956.08 / 154
T1 = 207.50
The initial temperature of the metal was 207.50°C

Explanation:
Chemists and Physicists use controlled experiments and scientific tools like microscopes and spectrometers to study the chemical and physical properties of matter.
Scientists, particularly Chemists and Physicists, are the ones who use experiments and scientific tools to study matter. They conduct controlled experiments to investigate the physical and chemical properties of different types of matter. For instance, they utilize scientific tools such as microscopes, spectrometers, and calorimeters to measure, observe, and analyze matter at various levels. By using these tools, scientists are able to gather precise and reliable data to better understand the composition, structure, and reactions of matter.

548.55 grams of aluminum hydroxide should theoretically form.
Explanation:
Balanced equation for the reaction:
3 NaOH + Al ⇒ Al(OH)3 +3 Na
DATA GIVEN:
mass of NaOH = 842 grams, atomic mass =39.9 grams/mole
mass of Al = 750 grams, atomic mass = 26.9 grams/mole
aluminum hydroxide theoretical yield = ?
Moles of NaOH reacted
number of moles =
putting the values in the equation
NaOH =
= 21.1 MOLES OF NaOH
Al =
= 27.8 moles
from the equation
from 3 moles of NaOH 1 mole of Al(OH)3 is produced
21.1 moles of NaOH will react to give x moles of Al(OH)3
=
7.03 moles of Al(OH)3 is formed.
and
1 mole of Al(OH)3 is formed from 1 mole of Al in the reaction
so, 27.8 Moles will react to give give 27.8 moles of Al(OH)3 limiting reagent of the given reaction is NaOH
mass of Al(OH)3 =7.03 x 78 (atomic mass of Al(OH)3)
= 548.55 grams
theoretical yield from the given data is 548.55 grams
