The lower limb bones are attached to the axial skeleton by a ring of bones called the pelvic girdle. The pelvic girdle consists of the right and left hip bones.
The bones of the head and trunk of the vertebrate form the axial skeleton.
Answer:
B. nuclease (destroys DNA and RNA)
Explanation:
Viruses are the particles that contain a protein coat called the capsid. Inside the capsid, viruses have their genetic material. Viruses may have single-stranded or double-stranded DNA molecules or single-stranded or double-stranded RNA molecules as their genetic material. Therefore, to destroy viruses, one must target their genetic material. Nucleases are enzymes that digest nucleic acids (DNA and RNA). The use of nucleases would destroy the genetic material of viruses and would be most effective to control them.
The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).
Explanation:
Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.
Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.
= 300 g
Thus, we can conclude that weight of Tris-HCL required is 300 g.
