Experimentation is a scientific process wherein you test and verify a hypothesis based on its assumption is going to be supported or negated (null hypothesis). Hence experimentation involves the independent and dependent variable, also control variable as a level in the IV. </span>
Answer:
Energy Transformation
Explanation:
The conversion of energy from one from to another is known as energy transformation.
Energy can only be converted or transferred from one object to another or to a different location but it can never be created from scratch. A good example is given in the question that solar energy is converted into chemical energy with the help of plants.
I hope the answer is helpful.
Thanks for asking.
The question is incomplete. The complete question is attached below.
Answer:
1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.
2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.
3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .
4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.
Answer:
option d
Explanation:
Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.
