Answer: I would say that the most common elements in living organisms are: 1)Oxygen
2)Carbon
3)Hydrogen
4)Nitrogen
Explanation:
1)Oxygen is the most abundant element contained within the living organisms, composing about 65% of the human body. It is also critical for cellular respiration in all aerobic organisms.
2)Carbon is essential for the survival, growth and reproduction of living things. It is a finite resource that comes in different forms and transfers from living to non-living things in various ways.
3)Hydrogen is important because it is involved in the process of enzyme catalysis and because it stabilizes things like nucleic acids and proteins.
4)Nitrogen is an important part of building amino acids and nucleic acids, both which are critical for maintaining life. Amino acids and nucleic acids are essential building blocks for cellular growth and repair in organisms in the form of protein.
It can attacks a cell because germs spread fast throught the body and that is why you need medication to help you when you are sick so it does not get worse so if you have a virus you need medication so it does not harm you even more.
Answer:it depicts asexual reproduction occurring through binary fission, a process that does not lead to genetic variation
Explanation:
Answer: The blanks can be correctly filled up with prophase I and metaphase II.
Explanation:
In females, finite number of oocytes are present since birth. The process of oogenesis initiate in embryonic stage only. However, oogonia divide and mature to form primary oocytes. These primary oocytes start meiotic division but arrest in prophase I stage before birth.
After a girl attains puberty, one primary oocyte resumes its division each month during a menstrual cycle. The primary oocyte divides to form secondary oocyte and polar body.
Polar bodies degenerate after completing meiosis II. However, secondary oocyte halts its division again at metaphase II until fertilization takes place. Once fertilization takes place it completes its meiosis II and results into mature ovum and polar body.
<span>It produces progesterone.The ovaries produce the female hormones estrogen and progesterone, in addition to a minute quantity of testosterone. Each ovary has thousands of follicles competent of generating eggs for fertilization. The brain cause the ovaries to develop a single mature egg cell for potential fertilization.</span>
