Answer:
C, E, B, D, A
Explanation:
Mitosis is the process by which a cell divides to form two cells. This involves the duplication of the genetic material. Therefore, mitosis begins with one diploid cell (diploid = 2 copies of the genome), and ends with two diploid cells (C).
Mitosis is a widespread process, occurring in all eukaryotic cells. This includes humans, animals, and single cell species (E)
Mitosis generates new daughter cells with the same genetic information as the parent cells, therefore it results in cellular reproduction, and regeneration of the individual organism through faithfully copying the genetic material (B)
Mitosis is a type of cell division. In mammals, a specialized type of cell division called meiosis is the process that is important for sexual reproduction. In some single celled organisms, mitosis can lead to a process of asexual reproduction in which the cell divides in two, producing a replica with an equal number of chromosomes (D)
Mitosis involves the passing on the genetic information, and increasing the number of cells (proliferation). Therefore, it is involved in development and growth of an organism, replacing old cells, and in asexual reproduction (some organisms can perform "budding" to reproduce using mitosis) (A)
Answer:
The answer is very likely C.
Explanation:
This becomes easy once we remember that DNA and RNA are not identical - which is why they have different names, RNA = 'ribo', DNA = 'deoxy.' This eliminates choice (A). While they are different, they are not incredibly different - DNA and RNA are both made up of nucleotides - they are not however, made up of Amino acids. Amino acids are what they can <em>code</em> for, and subsequently create proteins during protein synthesis. This helps us eliminate (B). Finally, we know that in order for something to have base <em>pairs</em> it needs to be double stranded - which RNA is not. Which means that because RNA is not double stranded (its singly stranded) that the answer cannot be (D). Leaving us with the only plausible option; (C).
Answer:
Blood is composed of several types of cells:
- <u>RED BLOOD CELLS</u>: They are the oxygen carriers of the body i.e. they pick up the oxygen as the blood goes through the lungs & release of oxygen to cells.Also known as erthrocytes
- <u>WHITE BLOOD CELLS</u>: also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)
- <u>PLATELETS</u> : helps in the blood clot in response to any wound or injury
There are five types of white blood cells & approx %age they made up in blood are:
•Neutrophils (55% to 70%)
•Band neutrophils (0% to 3%)
•Lymphocytes (20% to 40%)
•Monocytes (2% to 8%)
•Eosinophils (1% to 4%)
•Basophils (0.5% to 1%)
When children are more than 4 year old they have higher % age of lymphocytes than the adults do.
What are the living conditions like for all the animals except the pigs and dogs?
