Answer:
mutualism and parasitism
Examples:
mutualism: crocodiles and birds
parasitism: mosquitoes and humans
Microorganisms such as bacteria can be removed by disinfection. Certauns substances called biocides are addes to water to make it pure. Purification can also be done by UV-light .
Classification systems are essential to science; they act as the scaffolding that enables scientists to stand up close and get to know plants
Answer:
Genetic mapping for unequivocal identification of the potentially causative mutation
Explanation:
Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
Answer:
The Genotype of an organism determines the genetic characteristics of an individual.
If a father produces sperm that carry only 't' alleles, the his genotype will be 'tt' or hom.ozygous genotype.
Hom.ozygous genotype contains the same type of genes responsible for a particular phenotype.
Hence, the correct answer is 'tt' or hom.ozygous genotype.
