There have been various theories for the proof of evolution like structural similarities in an embryo formation pointed towards common ancestors. Theory of Natural selection embarked by Charles Darwin to show genetic variations picked by organisms in whole population.

The most authentic theory over evidence for evolution is Paleontological theory which includes study, observation and acquired prove of fossils of various organisms in the forms of Petrified, mold and cast, trace fossils, compression fossils, impression fossils, etc.

Sindrei [870]

Answer:

C. -independent, dependent, intervening

Explanation:

Independent variable is defined as the variable that can be changed during the experiment, dependent variable is the variable which is being tested and whose value depends on independent variable and intervening variable impacts the relationship between a dependent variable and an independent.

How does ATP supply energy for cellular activities?What do all cellular activities in living organisms use as a source of energy
Korolek [52]
  • ATP supplies energy for cellular activities by releasing one of the phosphate group in its molecule
  • Cellular activities in living organisms make use of ATP as source of energy

<h3>What is ATP?</h3>

ATP stands for Adenosine triphosphate and it is an energy carrier molecule in living cells of an organism.

The ATP molecule is made up of three components namely;

  • Nitrogenous base
  • 3 Phosphate groups
  • Five carbon sugar

The ATP molecule gains one phosphate group when it stores energy and loses one when it releases energy.
