A nucleotide, the building block of nucleic acids such as DNA or RNA, consist of a nitrogenous base, a pentose sugar, and one or more phosphate groups. It does not include lipids.
A nucleotide is the basic building block of nucleic acids like DNA and RNA. It consists of three main components: a nitrogenous base (which can be a purine like adenine or guanine, or a pyrimidine like cytosine, thymine, or uracil), a pentose sugar (which is either deoxyribose in DNA or ribose in RNA), and one or more phosphate groups. Lipids are not a component of a nucleotide, so the answer to your question would be lipids.

B. A gamete carries one allele for a gene.
C. A gamete can carry multiple alleles for a trait.
D. Some gametes are dominant and some are recessive.
The principle of segregation given by Gregor Mendel based on his experiments with the pea plants states that alleles of a gene for any trait are segregated during the formation of the gametes. Therefore, a gamete contains only one allele of a gene. When the male and female gamete combines during fertilization, the two alleles (one from each gamete) combine to form the gene.
Hence, the correct answer is 'Option B - A gamete carries one allele for a gene'.
Answer: The correct answer is- B. A gamete carries one allele for a gene.
Gamete ( also called sex cell or reproductive cell) is a haploid cell ( having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to Mendel's second law of inheritance that is law of segregation,
For every trait/ characteristic of an individual, there are two variant forms of a gene (called alleles) that are separated from one another so that every gamete possesses one allele. This law is also known as law of purity of gametes.
Thus, option B) is the right answer.
Answer: The theory of tectonic plates says that the outer shell of the earth is divided into many plates. These plates glide over the mantle. The plates acts as the hard and rigid shell when compared to the earth's mantle. All the continents and sub continents are based on plates, continental drift can result in earthquake, tsunami, volcanic eruption.
