The earliest hominin that belonged to the same genus as modern humans was homo habilis.
While working in labs with chemicals or specimens one should follow good laboratory practices. Professional conduct and manner should be maintained during working in labs.
The action that should be taken by a student is:
Option B. Wear a lab apron or lab coat over the clothing.
The good lab practices can be explained as:
- To avoid staining clothes individuals should wear lab coats over their clothes.
- Lab coats avoid staining and splashing your skin and clothes from chemicals and dyes.
- Lab coats are designed to protect against corrosive chemicals from soaking into the skin.
Therefore, the student should wear lab coats and aprons.

Answer:
Salmonella enterica (bacteria that causes food poisoning).
Explanation:
All living organisms has been classified into a main large group called DOMAIN consisting of three classifications: Eukarya, Archaea and Bacteria. The major basis of this classification is the possession of a true nucleus that houses the genetic material in the cells of living organisms.
Organisms that possesses a membrane-bound nucleus were classified to be under the domain Eukarya while those that didn't possess a nucleus were classified as Prokarya, which consists of the bacteria and archaea domains.
Based on the question, Salmonella enterica is a bacterium species, which means that it is a Prokarya and does not possess a membrane bound nucleus, hence, it would not be classified under the domain EUKARYA.
The probability that the daughter is a heterozygote for both genes is 1.0
What is achondroplasia dwarfism?
The fibroblast growth factor receptor is a protein in the body that is impacted by the genetic disorder achondroplasia. This protein starts to behave incorrectly in a condition called achondroplasia, which slows the formation of bone in the growth plate cartilage.
As achondroplasia dwarfism is an autosomal dominant disorder it will be passed on to the daughter.
What is red-green color blindness?
The most prevalent form of color blindness is red-green color blindness. This disorder, also known as deuteranopia, is most likely a congenital one. In this, the person is unable to distinguish between red and green colors.
As this disease is X-linked and the mother is affected hence it will be transmitted to her daughter.
Hence, the daughter will carry the genes for both diseases and thus will be heterozygote.
