Adenosine Triphosphate Living organisms store chemical energy in the form of biomolecules. Organisms transform these biomolecules to other forms of energy when needed. For example, chemical energy is transformed into mechanical energy when a muscle uses energy to move. Adenosine triphosphate (ATP) is the most important biomolecule that provides chemical energy. ATP is like a storage unit of chemical energy for the cell. It’s the most abundant energy-carrying biomolecule in cells. The structure of ATP consists of a nucleotide made of an adenine base, a ribose sugar, and three phosphate groups. ATP releases energy when the second and third phosphate molecules are broken, forming adenosine diphosphate (ADP). ADP can also form adenosine monophosphate (AMP), but this reaction releases less energy than the reaction that converts ATP to ADP.

Frost wedging occurs when water seeps into a crack in a rock, freezes, and causes the crack in the rock to widen. true or false?

Answers

It is true that frost wedging occurs when water seeps into a crack in a rock, freezes, and causes the crack in the rock to widen.

The statement is - True.

The frost wedging is one of the processes that contribute to the physical weathering of the rocks. Basically, if the rock has a crack, water manages to get into that crack. On the places where there's winters and the temperature drops bellow zero, the water in the crack of the rock freezes. Because the ice is expanding, it creates a lot of pressure inside the rock. Because of this pressure, the rock eventually cracks into two or more pieces. There have even been recorded cases where this form of weathering resulted in explosion of the rocks, where the pressure inside the rock was so big, that it has literary exploded, but that is very, very rare.

New cells are produced within the uterus as a direct result of

Answers

The best answer to the question above would be mitotic cell division. New cells are produced within the uterus as a direct result of mitotic cell division. Mitosis and cytokinesis are together to define the mitotic cell division of the mother cell split into two daughter cells.

Answer:

New cells produced within uterus (or any other organ) as a direct result of mitotic cell division.

Mitosis is the type of cell division which results in the formation of two daughter cells with same number of chromosomes as that of parent cell. It plays an important role in growth and repair of cells and tissues in multi-cellular organisms such as human beings.

For example, mitotic division helps in formation and repair of uterus lining lost during menstrual phase. Similarly, it keeps replacing the dead skin cells lost from our body surface on regular basis.

Meiotic division on other hand is used only in the formation of haploid gametes i.e. sperm in males and egg in females.
