Explain the following :
acrosome,
evolution,
chromosome,
speciation.
Answers
Answer:
Acrosome. The acrosome is an organelle that develops over the anterior half of the head in the spermatozoa (sperm cells) of many animals including humans. It is a cap-like structure derived from the Golgi apparatus. In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin).Explanation:
Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits
A chromosome is a DNA (deoxyribonucleic acid) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.
) Speciation is defined as the process by which new species are formed in the course of evolution. ... In speciation, a single evolutionary lineage gets split up into two or more independent lineages which are genetically different.
Answer:
acrosome is a covering of sperm head
evolution is the study of history of life
chromosome are the functional unit of inheritance
speciation is the origin of new species with time
