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.
<h2>
<em>The law of segragation, the law of independent assortment, and the law of dominance.</em></h2>
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells in order that sex cells contain only 1 gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for various traits are sorted separately from each other in order that the inheritance of 1 trait isn't smitten by the inheritance of another.
3) The Law of Dominance: An organism with alternate types of a gene will express the shape that's dominant.
Developing Nations currently produce about 2600 kcal of food per person per day. The growth in food consumption around the world has been accompanied by a significant structural changes and a shift in the diet away from the staple foods such as roots and tubers towards more livestock products and vegetable oils.
Answer:
Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.
Explanation:
Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.
Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.
