What types of evidence do scientists use to determine evolutionary relationships among groups
lions [1.4K]
There are several things that can help scientists evaluate which category something belongs to. The similarity in features is one of them. If two skulls looked alike, they were probably species of the same evolutionary category. For example say humans and monkeys rather than humans and dogs.
Similarly fossils have helped scientists categorise species. Study of the chromosomes (in cases with available chromosomes) can help scientists figure out a lot about the subjects and categorise them.

When atp is hydrolyzed to power a condensation reaction, what happens to the phosphate molecule that is released?
Leto [7]

The phosphate molecule that is released it is coupled to a different ADP molecule to make new molecule of ATP.

Hydrolysis of high-energy compound (ATP) using water:

ATP + H₂O → ADP + Pi

ATP is short for adenosine triphosphate.

Hydrolysis is a reaction that breaks down the chemical bonds between molecules via the addition of a water molecule.

A condensation reaction is a reaction that joins two molecules in a chemical bond.

ATP is resynthesized in a condensation reaction that adds an inorganic phosphate group to ADP. The addition of a phosphate group is catalyzed by the enzyme ATP synthase.

3) In the reaction below, how many grams of carbon dioxide are produced when iron III
Yanka [14]
<h3>Answer:</h3>

132.03 g

<h3>Explanation:</h3>

<u>We are given;</u>

  • The equation for the reaction as;

Fe₂O₃ + 3CO → 2Fe + 3CO₂

  • Molar masses of CO and CO₂ as 28.01 g/mol and 44.01 g/mol respectively
  • Mass of CO as 84 grams

We are required to calculate the mass of CO₂ that will produced.

<h3>Step 1: Calculate the number of moles of CO</h3>

Moles = Mass ÷ Molar mass

Molar mass of CO = 28.01 g/mol

Therefore;

Moles of CO = 84 g ÷ 28.01 g/mol

                     = 2.9989 moles

                    = 3.0 moles

<h3>Step 2: Calculate the number of moles of CO₂</h3>
  • From the reaction, 3 moles of CO reacts to produce 3 moles of CO₂
  • Therefore; the mole ratio of CO to CO₂ is 1 : 1
  • Hence; Moles of CO = Moles of CO₂

Moles of CO₂ = 3.0 Moles

But; mass = Moles × molar mass

Thus, mass of CO₂ = 3.0 moles × 44.01 g/mol

                                = 132.03 g

Hence, the mass of CO₂ produced from the reaction is 132.03 g
