Billions of years ago Earth was just a planet made out of rocks. After the Big Bang Theory, Earth was being formed. After it was formed it took years and years for life to even start on earth. What started life was when Earth started to produce it's own water then soon it made volcanoes which made islands which formed into gigantic places that we call home. Later on Earth started to produce it's own weather and atmosphere. As earth had it's first rainfall, the ground started to grow green leaves that we call grass and trees. With those changes, life was starting to be born. The first living things on Earth, singled-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokarotes. Later on the the organisms starting producing more organism which evolved later into human and animal life.

The answer would be a.
Biological catalysts are generally proteins (and a group of RNA molecules called ribozymes), but carbohydrates do not play such a role.
Hello.
TP is a molecule with adenosine and three phosphate groups attached to it (adenosine triphosphate). To get energy from ATP, one of the bonds between the phosphates is broken, yielding energy and the molecule ADP - adenosine diphosphate, a molecule with adenosine and two phosphates.
<span>In order to 'recharge' the molecule, a phosphate group is re-attached to ADP by ATP-synthase to yield ATP. In other words, energy is stored in the bonds between phosphates, and breaking the bond releases that energy.

Answer:
Sister chromatids. (Ans. B)
Explanation:
Sister chromatids are defined as the identical chromatids formed by the DNA replication of the chromosome, both copies of chromatids are joint together by a centromere. A pair of chromatids are known as dyad.
A set of sister chromatids formed during the S phase or synthesis phase of interphase, while all the chromosomes present in a cell is replicated. During the process of mitosis, or second division of meiosis the two sister chromatids are gets separated from each other into two different daughter cells, and each cell receives one copy of the chromosomes.
Answer:
Enzymes are biological catalysts which speed up biochemical reactions.
