Explain the Law of Conservation of Energy.

1 answer:

3 0

The law of conservation of energy is one of the basic laws of physics and therefore governs the microscopic motion of individual atoms in a chemical reaction. The law of conservation energy states:

In a closed system, i.e., a system that isolated from its surroundings, the total energy of the system is conserved.

In SI units, energy has units of Joules. 1 Joule = 1 kgms.

Some forms of energy:

1.Kinetic energy - energy of motion.2.Potential energy - energy of ``location'' with respect to some reference point.3.Chemical energy - energy stored in chemical bonds, which can be released in reactions.4.Electrical energy - energy created by separating charges; energy stored in a battery, for example.5.Thermal energy - energy given off as heat, such as friction.

ATP is thermodynamically suited as a carrier of phosphoryl groups in animal cells because of all EXCEPT ________.

STatiana [176]

Answer:

It is intermediate in group-transfer potential

Explanation:

Adenosine triphosphate (ATP) is an organic chemical that provides energy to drive many processes in living cells.

ATP is the molecular energy currency of the cell.

ATP is the molecule that hydrolyses ADP and Pi.

Living cells maintain the ratio of ATP to ADP at a point ten orders of magnitude from equilibrium, with ATP concentrations fivefold higher than the concentration of ADP.

The chromosomal mutation in the zygote can be traced back to which of the following? (4.3, 4.4)Immersive Reader

lawyer [7]

The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".

Option: B

Explanation:

In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.

Chromosomal mutations are often caused by chemical agents or by mutagens. The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.

WINSTONCH [101]

The dependent variable is what changes because of the independent variable, while the independent variable is what is purposefully changed by the experimenter, since it is the variable that is being tested.

So, in this problem, you are purposefully changing the distance of the race to see whether or not the amount of time taken to complete the race will change because of the varying distances.

This means that purposefully changing the distance of the race is the independent variable that is being tested and that the amount of time that the runner takes to complete the race is the dependent variable because it changes due to the independent variable.

Sorry for being so wordy.

In short,

Independent variable- the one that's being tested and that is purposefully changed.

Dependent variable- the one that changes because of the independent variable.

Hope this helps.
