Evidence for evolution reveals that closely related organisms have many similar  physical and genetic characteristics.

Explanation:

Closely related organisms have similar physical features and genetic sequences.

When both the physical and genetic features are similar, these organisms are referred to as homologous structure.They are similar, as their evolutionary path is the same.

Example: bones from the birds and arms of the humans, have evolved more or less similarly so they are homologous structure.

In other cases, the organisms might be closely related, but their genetic structure might have a slight change. Due to this change there might be difference in the physical structure.

Example: the chimpanzee and  human have different physical structure even though their evolution have taken the same path and they are closely related.

When dissolving a solid or liquid, as the temperature of the solvent increases, the rate of dissolution?
Alinara [238K]

Answer:A. Increases

Explanation:

Heating or an increase in temperature increases the kinetic energy of particles thereby increasing their motion and how they relate and react with one another.

Increase in the temperature of the solvent is directly proportional to the rate of dissolution. The rate of dissolution increases due to the increase in kinetic energy. This makes the solvent particles interact faster with the solute particles thereby increasing the dissolution rate.

What is the difference between acute and chronic radiation poisoning
tatiyna
Acute radiation can be healed by developing cells (white blood cells) in the body. During Chronic radiation immense amount of energy is released into your body causing division and break down of cells which can cause cancer and internal bleeding and cannot be cured depending on the amount released.

PLEASE HELP!
Tanzania [10]
Molar mass:

KCl = 74.55 g/mol

KClO3 = 122. 55 g/mol

  <span>Calculation of the mass of KClO3 :</span>

<span>2 KClO3 =  2 KCl + 3 O2</span>

2* 122.55 g KClO3 ------------------ 2 * 74.55 g KCl
mass KClO3 ?? --------------------- 25.6 g KCl

mass KClO3 = 25.6 * 2 * 122.55 / 2 * 74.55

mass KClO3 = 6274.56 / 149.1

mass = 42.082 g of  KClO3

Therefore:

1 mole KClO3 ---------------------- 122.55 g
?? moles KClO3 ------------------- 42.082 g

moles KClO3 = 42.082 * 1 / 122.55

moles KClO3 = 42.082 / 122.55

=> 0.343 moles of KClO3
