A person who specializes in the study of animals is called a zoologist. Zoologists who study certain kinds of animals have their own names.
Heyo!
I'm pretty sure that its A, because the others are not valid in my opinion.
Also I'm not sure if this question is in the right category.
Lots of love!~
In biology, cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects, plants or animals reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms (organism cloning). The term also refers to the production of multiple copies of a product such as digital media or software.
The term clone, invented by J. B. S. Haldane, is derived from the Ancient Greek word κλών klōn, "twig", referring to the process whereby a new plant can be created from a twig. In horticulture, the spelling clon was used until the twentieth century; the finale came into use to indicate the vowel is a "long o" instead of a "short o".Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.
Hornblende and other amphiboles have double chain silicate structures.
Tetrahedron (SiO4)^4- is the fundamental building block of all the silicate minerals. Silicate minerals comprising chains are known as inosilicates. In single chains, the ratio of silicon to oxygen is 1: 3, while it is 4: 11 in the case of double chains.
The double-chain silicates take place when tetrahedral produce a double chain by sharing two or three oxygen atoms each.
B.A.D I think not too sure
