Hello,
Question:
Over time bacteria get used to anti bacterial medicine. Doing this can add symptoms and take away the easiest process of healing grout the human and destroying the bacteria.
Using complete sentences, explain how this speeds up the process of evolution in bacteria.
Answer:
Well, the reason medicine speeds up the evolution of bacteria because it needs to put the medicine ineffect for the vaccine to work properly. The faster it works the easier and less painful it will be for that person. Thats why when they go to hospitals they try to give treatment as fast and quickly as possible so there is no further damage. The medicine works almost instantly.
Edited Answer:
The reason bacteria can evolve faster because the DNA which is sharing which the evolution happen much faster, mostly because you don't have to rely on mutations.
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes.
Answer:
The best answer from the list of options is option D (They are colorless and feed on other, smaller cells)
Explanation:
Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.
Answer: The correct answer would be corpus albicans.
Explanation:
After ovulation, the ovarian follicle converts into corpus hemorrhagicum. After some time, it converts into a temporary endocrine structure termed as corpus luteum. It maintains high levels of progesterone which is necessary for maintenance of uterus lining.
However, in absence of pregnancy or fertilisation, the corpus luteum starts degrading and convert into the structure termed as corpus albicans.
