Answer:
taking the pretest
Explanation:
A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.
<span>Meiosis helps prevent mutations from occuring over and over again.
In Meiosis process, the number of chromosomes during reproduction was caused in half.
During this process, the chromosomes that could potentiall caused mutation could be tossed out and therefore reduce its chance from happening</span>
Answer: A) By increasing the need for genetic engineering of fish
Fish is a globally accepted source of food, with the increase in population all over the world the demand for fish as a source of food is also increasing. Genetic engineering is a field of biotechnology in which the genome of the organism is manipulated by addition, deletion or substitution. This is done to improve the productivity of the animals and plant crops and to obtain desires characteristics in them.
A) By increasing the need for genetic engineering of fish is the correct option which can directly improve fish agriculture because a fish species can be genetically modified so that it can be able to produce more number of offsprings and nutritious quality of flesh, useful for human consumption.
