<u>Bacterial growthon the agar in a Petric dish:</u>
Nutrient agar gives these assets to numerous sorts of organisms, from parasites like yeast and form to basic microorganisms, for example, Streptococcus and Staphylococcus.
The microorganisms that can be developed on complex media, for example, supplement agar can be depicted as nonfastidious life forms. Microscopic organisms are found in each natural surroundings on Earth: soil, rock, seas and even cold day off. Some live in or on different life forms including plants and creatures including people.
There is around 10 fold the number of bacterial cells as human cells in the human body. In the two people and microorganisms, a codon made of three thymine DNA-letters will code for an amino corrosive called Phenylalanine. This code is regular to the two people and microscopic organisms, and surely, for most living things.
Answer:
Brown eyed genotype: Aa (eterofzygous) or AA (homofzygous)
The genotypes derived from the cross are: AA, Aa, Aa, aa
The phenotypes are: 3 with brown eyes and 1 with blue eyes (aa)
A dichotomous key is created by scientist to identify objects and organisms.
Questions from a dichotomous key would be:
The fish have 1 eye or 2 eyes
Or if the alien have 2 heads or 1 head.
Answer:
<u>III → IV → II → I → V</u>
Explanation:
The first response would be binding of antigenic determinants from pathogen to the receptors on lymphocytes then lymphocytes would become active and they increase their quantity followed by secreting antibodies that will eventually destroy the pathogen. Memory cells will recognize this pathogen as foreign body and they will always remember it.
