Answer:
Ethics refers to some set of rule and regulations or principles, that ensure the right conduct in a definite professional or academic environment.
When we talk about lab ethics, there are a set of principles which a scientist need to follow to demonstrate excellent lab ethics.While working in laboratory a scientist must make sure that ethical standards are a priority of them. Here we will discuss few of those:
- A scientist should never manipulate the data and results just to make them in accordance with the previously reported studies.
- Scientist should properly document every protocol and process and take special care that no changes are made in experiment due to environmental influences that can affect the reliability of results.
- Scientist should always report the results and processes which he performed and never report work without actually doing it.
- Scientist should never omit some part of the experiment or compromise the data or results of experiment.
- Scientist should never manipulate the calculations.
- Every process or step that is part of a scientist's experimentation should be conducted before the finalization of the results and not perform procedure after results are made.
- Scientist should replicate his experimentation at least three times to make sure that what he is reporting is based on facts and not just error in experimentation.
- Scientist should never report self made information just to validate or proof his work.

Answer:
Hypothesis: If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue.
Explanation:
In a scientific research the hypothesis is an assumption, a possibility that will justify the purpose of the scientific research and will help in the establishment of all the steps of this research, so that it is possible to determine if the hypothesis is true or false. In other words, we can say that the hypothesis must be formulated as an assumption, before the research that will prove it or not.
An example of a hypothesis about research on the longevity of cells that line the esophagus is: "If mucus production in the submucosal layer of the esophagus is insufficient, cell longevity is affected, because it interferes with the quality of connective tissue."
Answer:
Firstly, we can use a DNA probe to identify the particular antibody gene that we are looking for.
We can cut the gene at specific restriction sites by using specific restriction enzymes.
The same restriction enzymes should be used to cut the DNA from the specific site in the maize plant.
The gene can be introduced and ligated in the maize genome by using DNA ligase.
The recombinant DNA can be places in the Maize cop plant.
Answer:
Sheep
Explanation:
Carnegie stages can be described as the period of maturation in mammals. It is during this period that they develop most of the body parts and organs that is needed for them to survive in the outside world. There are about 23 stages which classify the ways each mammals form and develop various features on their bodies.
The Carnegie Stages of development are unique to mammals this is because mammals carry their young one in their wombs, they stay there deriving nutrient from their mother until they are ready to be born. From the options listed above the mammal among the animals, there is sheep. Hence a sheep undergo Carnegie stage.
