The answer is (b.) fertilization
The fertilization is the stage where the egg cell or the so-called ovum fused with the sperm cell which eventually leads the development of the embryo or the zygote. The Embryogenesis starts when the zygote undergoes mitotic divisions or also known cleavage process.
b. Codon loop
c. The 3’ end
d. Variable loop
The correct answer is: a. Anticodon loop
tRNA or transfer RNA is an important component in protein synthesis (translation). Its role is to carry amino acids to the ribosome and link a matching a codon in an mRNA with the amino acid it codes for.
The anticodon located on the tRNA (anticodon loop) can bind to one or a few specific mRNA codons.
The correct option is c.
The 3' end of a tRNA molecule binds to amino acids during protein synthesis. Specifically, the CCA tail at this 3' end directly binds the amino acids.
The region of a tRNA molecule that binds to amino acids is the 3′ end. tRNA, which stands for transfer RNA, is crucial for protein synthesis in the cell. The amino acids are attached to the 3′ end of the tRNA molecule. While the anticodon loop, codon loop, and the variable loop are all important aspects of the tRNA structure, it's the 3' end, more specifically the CCA tail at this part, that directly binds to the amino acids during translation.

Hydrogen bonds are the forces that hold two DNA strands together in a double helix.
Deoxyribonucleic acid, also known as DNA, is made up of two lengthy strands that loop around one another to form a double helix. The nitrogenous bases of the DNA's nucleotides form hydrogen bonds with one another, holding the two strands together.
The four nucleotide bases adenine (A), thymine (T), cytosine (C), and guanine (G) make up DNA. Adenine and thymine make hydrogen bonds, and cytosine and guanine do the same. Adenine always couples with thymine, and cytosine always pairs with guanine, forming unique and complementary hydrogen bonds.

The bonding forces between two DNA strands in a double helix are hydrogen bonds that occur between the base pairs. DNA bonding hold the two strands together, enabling the DNA double helix to act as the stable carrier of genetic information.
The bonding forces between two DNA strands in a double helix are known as hydrogen bonds. These bonds occur between the base pairs in the DNA sequence. For each base pair, adenine (A) bonds with thymine (T) through two hydrogen bonds, and guanine (G) bonds with cytosine (C) through three hydrogen bonds. These hydrogen bonds are what hold the two strands of the DNA double helix together, allowing it to function as the stable carrier of genetic information.

B) ozone
C) chlorophyll
D) radiant energy
Plants use their leaves to capture light energy during photosynthesis, water and carbon dioxide are converted by plants into sugar, hence option a is correct.
Plants use glucose as a source of energy and to create other compounds like cellulose and starch and cell walls are constructed using cellulose.
In a process known as photosynthesis, plants use carbon dioxide, water, and sunshine to create sugar and oxygen.
Chloroplasts, tiny compartments found inside plant cells, are where photosynthesis takes place.
Therefore, the removal of carbon dioxide from the atmosphere and utilize water in the production of food make this a significant process for the planet, hence option a is correct.

water is the correct answer.
Answer: ligament
Explanation:
B. nucleolus.
C. chromatin.
D. DNA.
Answer:
Option A, Cytoplasm
Explanation:
Cytoplasm is the fluid contained with in the cell membrane into which all cell organelles are found including the nucleus. Cytoplasm basically has two parts a) endoplasm and b) ectoplasm. The endoplasm has all the organelles while the ectoplasm is the fluid at the periphery of cell membrane. The cell memebrane keep the cytoplasm confined with in the cell and does not allow it to spill.
Since all the cell components are found with in the cytoplasm, it is clear that cytoplasm lies out of the nucleus. Thus, option A is correct.
Answer:
The correct answer will be option- A
Explanation:
The nucleus is the membrane organelle which encloses the DNA of the organisms. The presence of the nucleus is the characteristic feature of the eukaryotes.
The nucleus encloses the genetic material in the form of either DNA or a loosely arranged structure called chromatin. The nucleus also contains a structure called nucleolus distinguished by a dense round structure during the interphase.
Since the nucleus lacks the cytoplasm which is enclosed by the cell membrane of the cell therefore, option-A is the correct answer.
