Introduction
The Mint polyploidy plant in this investigation has diploid sets of chromosomes which enables it to have advantageous characteristics in the environment: therefore it can adapt to unfavourable conditions better than a non-polyploidy plant.

Source A https://en.m.wikipedia.org/wiki/Polyploid What is polyploidy?
The generalised definition of polyploidy refers to an organism containing more than two paired homologous sets of chromosomes. It refers to the change in a whole set of the chromosome number that occurs due to a mutation.
Polyploidy in plants means that a plant has more than the diploid chromosome number in a normal plant, this can include triple the haploid chromosome number

THE ADVANTAGES AND DISADVANTAGES OF BEING POLYPLOID
|Polyploids — organisms that have multiple sets of chromosomes — are common in certain plants, and can be surprisingly stable. The evidence that has emerged from genome analyses also indicates that both humans and most other eukaryotes have either benefited from or endured polyploidy. Studies of polyploids soon after their formation have revealed genetic and epigenetic interactions between redundant
The stages of Meiosis II are: prophase II, metaphase II, anaphase II, and telophase II. Meiosis generates four haploid cells, which begins with the division of one diploid cell. Diploid means having two sets of chromosomes, and haploid means having half the number of genetic information as diploid (or one set). To begin, late interphase is the phase when the DNA in the diploid parent cell is replicated. Then, in prophase I, the chromatin condenses and the chromosomes become visible.
5. How do the processes of meiosis and fertilization produce genetic variety?
During the meiosis stage of crossing over, the maternal and paternal homologous chromosome segments are being exchanged. During independent assortment, different genes independently separate from one another.

BRASSICA RAPA INTERACTIONS WITH INTRASPECEFIC COMPETITION AMOUNG HIGH AND LOW DENSITY VARIABLE POPULATIONS
Abstract
Competition occurs in plants when there are a limited number of resources. Certain traits that affect advantages or disadvantages in between organisms. Our hypothesis for our experiment that intraspecific competition in low and high density treatments would affect height and survivorship for Brassica rapa.
Pros/Cons of GMOs
GMOs or Genetically modified foods are convenient to manufacture but do
you know how GMOs were initially produced or the amount of money you will squander attending the hospital? Not only that, GMOs are a problem considering the net amount of money countries such as the U.S. owe, the insufficient amount of examination that has been accomplished, and then the accidental creation of pesticide resistance weed. Although GMOs help feed everyone which is its intended purpose, little do people know the chemicals in the foods are unquestionably harmful, because of this lack of testing and creation of stronger enemies and destruction of things we need.
To commence, GMOs are unacceptable because of the unhealthy chemicals
put into it and the amount of debt various countries are in because of it.
Introduction-
The discourse community of scientists in the field of genetics attempt to find solutions to problems with genes, and heredity. For over a century, popular articles have played a crucial role by building a communication medium between scientists and their audience who are people interested in keeping up with the upcoming science. These articles have been influenced by changes in the audience, exigence, and constraints experienced by the community. Therefore, by analyzing the changes in the popular articles through the years we can understand the growth of the discourse community.
Introduction:
This lab report outlines an experiment on the observation of mitosis in the cells of garlic root tips. Mitosis simply put is the division of a nucleus producing two daughter cells with the same number of chromosomes as the parent cell. Miotic cell division consists of five stages: Interphase, Prophase, Metaphase, Anaphase and Telophase. The purpose of this experimet was to identify and observe cells within each stage of mitosis using garlic root tip cells.
3-2-1 Assignment- Natural Selection and the Forces of Evolution
3 Main Points:
1. Natural Selection has three basic principles. One of those principles states that strong organisms will survive and the weak organisms will die. The second principle states that all organisms are different. The last principle states that inheritance comes from the parents’ genes, so 50% of those genes are from one parent and the other 50% is from the other parent.
Whilst it is very successful at this, and is in most cases necessary to the plant, the very mechanism by which it reproduces (mitosis) does not result in much genetic variation. Should an environmental change come along for which the species is not adapted, it is likely that it will be wiped out entirely. This is because none of the individuals have developed any mutations or genetic adaptations that allow them to survive in that
Eugenics is the science of using artificial selection to improve genetic features of the population. It is thought that improvement of the human race can be seen through sterilization of people who exhibit undesirable traits and selective breeding. Often called Social Darwinism, the concept was widely accepted during the time of World War I. It quickly became a taboo after World War II when Nazi Germany used it as an excuse for genocide. The thought of improving the human race by manipulating who is allowed to breed can either be appalling or compelling.
There are four main perspectives in psychology. These are known as; biological perspective, learning perspective, cognitive perspective, and sociocultural perspective. Each perspective aids in the understanding of human behavior. However, not one perspective can explain all of human behaviors. This is due to each perspective playing different roles in ones behavior.
Artificial Selection/ Natural Selection
When the word artificial comes to my mind fake thoughts run through me, like water runs down your throat. Artificial christmas trees, flowers, foods, anything artificial you can think of, almost everyone has it and has produced it. As you read this, do you have any idea what artificial means? Said on dictionary.com, artificial means produced by humans, not occurring naturally. For example, artificial selection would be taking a wild animal, such as a whale, living in the huge ocean and putting him/her in a place like Seaworld, where they don’t adapt to the environment well, and are not used to the resources and rules.
Is Genetic engineering Safe?
Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not.
Introduction
Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today.
Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
