The energy transformations that occur in the given devices are as follows:
- Windmill - mechanical energy to electrical energy
- Flashlight - electrical energy to light energy
- Microwave - electrical energy to heat energy
- Firecracker - chemical energy to heat, light, and sound energy
- Bicycle - Chemical energy to mechanical energy
- Battery - chemical energy to electrical energy
<h3>What is energy transformation?</h3>
Energy transformation refers to the processes by which one form of energy is transformed into another form.
The law of conservation of energy guides the various energy transformations that occur in the universe.
The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.
The energy transformations that occur in the given device are as follows:
- Windmill - mechanical energy to electrical energy
- Flashlight - electrical energy to light energy
- Microwave - electrical energy to heat energy
- Firecracker - chemical energy to heat, light, and sound energy
- Bicycle - Chemical energy to mechanical energy
- Battery - chemical energy to electrical energy
In conclusion, energy transformations occur according to the law of conservation of energy.

2 chains and 4 nucleotides
Answer: three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein. The nucleotide sequence in the DNA is first transcribed into a molecule of messenger RNA (ribonucleic acid
There are high risk of following abnormalities or mis- happening if chorionic villus sampling (CVS) are performed before 10th week of pregnancy:
a) Fetal defects
b) Miscarraige
c) Fetal anomalies.
d) Risk of infection
As per the standard recommended by American Congress of Obstetricians and Gynecologists, the standard time to perform this test is between 10th & 12th week as at that time the chances of risk to fetus is very negligible. In no case CVs shall be conducted before 9th week of gestation.
It is estimated that there is a risk of 0.5 to 1 % of miscarriage after CVs which usually happens within the 3rd day of test.
