Explanation / Answer

Organisms can be classified in to taxonomic levels:Domain,kingdom,phylum,class,order,phylum,genus,species.

Adaptation:acclimitizing to particular environment or food etc.,adaptatons helps animal to survive,Adaptation can be how an animal looks or behaves.

Wallace :He is an naturalist have ideas similar to darwin ,that species changed overtime because of theri struggle for existence.

Biosphere:Sum of all ecosystems.

Allele:Alternate expression of gene .

Anaphase:Chromosomes separated and moves towards the poles

Bottle neck effect:Decrease in the population due to humans or environmental interferance.

Charles darwin:He is an naturalist,biologist ,his theory of evolution explains how species of organisms change overtime

Codominance:Both alleles og gene are expreessed in heterozygous offspring

Community:Two or more species interacting with each other .

Cytokinesis:cytoplasm of single eukaryotic cell divides in to two daughter cells.

Diploid:cell with 2 sets of chromosomes

Dominant allele:Dominant allele is allele that is expressed when two different alleles are presant .

Ecosystem:it includes both biotic and abiotic components

Eukaryotic:organisims with definite nucleus and nuclear membrane

Evolution:Gradual chnge in species over time .

Founder effect :It occurs if small number of individuals colonize a new area

Gene:segment of DNA that codes foe protein

Gene flow :Movement of alleles from from one population to another .

Gene pool:Total number of genes in aparticular population

Genetic drift:Change in gene pool population by chance

Genome:Organisms entire hereditary information

Genotype:genetic make up of organism

Gregor Mendel: He is "father of modern genetics,

Haploid:Organism with single set of chromosomes

Heterozygous:made up of two different alleles

homologous pair:Chromosomes with similsr genes one from mother and another from dad.

Homozygous:made up of two similar alleles

Hybrid:Offspring of crosses between two different species

Malaria:Malaria is a mosquito-borne infectious disease caused by plasmodium

Meiosis: reduces the chromosome number by half,results in 4 daughter cells

Metaphase:Siater chromatids line up in center od spindle fibers

Mitosis:Having same number of chromosomes ,results in 3 daugther cells

Mutation:Change in organisms DNA

Natural selection :Process by which traits become more or less common in population

Non randon mating:Certain traits increase mating success

Organism:Made up of 2 or more cells

Phenotype:Observable characteristics of organism.

Population:Made up of number of organisms of same species

Prezygotic barriers:Block fertilization from happening

Postzygotic barriers:Occurs after zygote is formed

Prokaryotic:Primitive organisms with no distinct nucleus

Recessive allele:It is expressed when paired with other recessive allele

sex linked genes:Genes that are located on sex chromosomes

Sickle cell anemia:Genetic disorder in which RBC cells becomes sickle shaped

sister chromatids:Two identical copies of chromosomes connected by centeromere

Telophase:Chromosomes are at poles and forms 2 cells .

Temporal lobe:Paired lob of brains that helps in understanding speech

vestigial:These are structures that are no longer in use but are functional in ancestors.
