Question 1

DNA

Answer 1

Deoxyribonucleic acid is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses

Question 2

Nucleotide

Answer 2

Nucleotides are organic molecules that serve as the monomer units for forming the nucleic acid polymers deoxyribonucleic acid and ribonucleic acid, both of which are essential biomolecules in all life-forms on Earth. Wikipedia

Question 3

Chargaff’s Rules

Answer 3

state that DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine

Question 4

Watson and Crick

Answer 4

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s.

Question 5

Rosalind Franklin

Answer 5

osalind Elsie Franklin was an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite

Question 6

Mutations

Answer 6

In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements

Question 7

Adaptation

Answer 7

Nicolas Cage is Charlie Kaufman, a confused L.A. screenwriter overwhelmed by feelings of inadequacy, sexual frustration, self-loathing, and by the screenwriting ambitions of his freeloading twin brother Donald (Nicolas Cage)

Question 8

Species

Answer 8

a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g., Homo sapiens.

Question 9

Evolution

Answer 9

Evolution is change in the heritable characteristics of biological populations over successive generations

Question 10

Fossils

Answer 10

A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, hair, petrified wood, oil, coal, and DNA remnants.

Question 11

Fossil Record

Answer 11

A term used by paleontologists ( see paleontology ) to refer to the total number of fossils that have been discovered, as well as to the information derived from them.

Question 12

. Charles Darwin

Answer 12

Charles Robert Darwin, FRS FRGS FLS FZS was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution

Question 13

Trait

Answer 13

a distinguishing quality or characteristic, typically one belonging to a person.

Question 14

Selective Breeding

Answer 14

elective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females

Question 15

Natural Selection

Answer 15

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time

Question 16

Generation Time

Answer 16

is the average time between two consecutive generations in the lineages of a population

Question 17

Speciation

Answer 17

Speciation is the evolutionary process by which biological populations evolve to become distinct species.

Question 18

Primates

Answer 18

A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines

Question 19

Hominid

Answer 19

he Hominidae, whose members are known as great apes or hominids, are a taxonomic family of primates that includes eight extant species in four genera: Pongo, the Bornean, Sumatran and Tapanuli orangutan

Question 20

Homo sapiens

Answer 20

Homo sapiens is the binomial nomenclature for the only known extant human species. Homo is the human genus
