Answer:I think it is part B
Explanation:
<span>The correct answer for the question is Non-disjunction. Non-disjunction occurs in cell division when chromosomes do not divide properly. It can occur during mitosis, meiosis I and meiosis II. In mitosis it occurs when sister chromatids fails to separate in Anaphase. The result is that one cell receives both chromatids, while the other receives neither. Each daughter cell then has an abnormal number of chromosomes when mitosis is complete; one cell has an extra chromosome, while the other is missing one. In anaphase of meiosis I, it happens when a pair of homologous chromosomes does not separate. In meiosis II, it happens when a pair of sister chromatids fails to separate properly during anaphase of meiosis II, one daughter cell will have an extra chromosome and one daughter cell will be missing a chromosome.</span>
An organism adapting to its environment leads it to be more ‘equipped’ for survival.
Competition is when other species fight for the same resources that another species needs. Also, it would produce offspring with these adaptations.
An example (to help you better understand);
A blue jay has great eyesight, strong wings, and sharp beak. (Better adapted organism) Another blue jay has great eyesight, weak wings, and dull beak. (The competitor/unadapted)
Both birds find the same food source and are now competing for it. The first bird has sharp beams, which is better for breaking, and ‘chomping’ the seeds/food. The second bird would struggle to consume its food (seed) unless it’s worms.
So which one is better adapted? The first blue jay.
And i hope this helped show how competition can be reduced.
Bacteria have different phage resistance mechanisms, such as spontaneous mutations, the CRISPR-Cas system.
Spontaneous mutations are the main mechanisms leading to phage resistance by altering the structure of bacterial wall components that act as phage receptors. These include lipopolysaccharides (LPS), outer membrane proteins, cell wall teichoic acids, capsules, and other bacterial components.
It would be an oncogene, these can be inherited mutations of proto-oncogenes that cause the oncogene.
