Answer: B. Alleles.

A variant form of any given gene is an allele. One of the two alternative forms of any particular gene which is present at the same locus of the chromosome is an allele.

Different forms of an allele determine the phenotypic traits. Most of the multicellular organisms are diploid having two sets of chromosomes, each inherited from one parent. If both the alleles of any gene are same on the particular position of chromosome then it is termed as homozygous and if the alleles of the gene are different, it is called heterozygous.

You find a 10,000,000 year old rock 2,500 km away from the nearest seafloor spreading center. The plate has been moving since its formation by (2,500 km)(100,000 cm/1 km)/(10,000,000 yr).so the plat has been moving equal to 25 cm per year since its formation.

hammer [34]

Answer:

➢The structure of a nucleus encompasses the nuclear membrane, nucleoplasm, chromosomes, and nucleolus. The nuclear membrane is a double-layered structure that encloses the contents of the nucleus. ... Like the cell membrane, the nuclear envelope consists of phospholipids that form a lipid bilayer.

➢ Such nuclear pores are the sites for the exchange of large molecules (proteins and RNA) between the nucleus and cytoplasm.

antoniya [11.8K]

Answer:

RNA has for nitrogenous bases out of which three are the same as DNA. The bases common to both DNA and RNA are Adenine (A), Guanine (G) and Cytosine (C). The one that is different is called Uracil (U).

The five carbon sugar in RNA is called Ribose sugar.

Explanation:

DNA consist of four bases that are A,T,C and G. Similarly, RNA also consists of four bases that are A,U,C and G.

Thymine (T) is not present in RNA, instead of it, RNA has Uracil (U) which binds with Adenine (A) by two hydrogen bonds.

The five-carbon sugar that is present in RNA is ribose and that present in DNA is deoxy-ribose. Ribose and deoxy-ribose differ at second carbon. Ribose has an OH at second carbon while in deoxy-ribose, O is missing at second carbon and it has only H.
