1) red blood cells
2)erythrocytes
3)keep them warm and seek help
Explanation:
I don't know if this will help you I was in first aid so the last one may or may not help you
Ecosystem
Explanation:
The relationship between the living and non-living things forms an ecosystem.
The non- living things like water, air, soil and other are required by the living organisms for leading their life cycle.
The living things forms the integral part of the natural cycling process of water, air and soil.
Thus this can be said that both living and non-living things are interdependent on each other and forms an ecosystem.
For example, if plants do not get water they will not be able to produce food also the transpiration will not occur which is an important part of the water cycle.
The given case says, the pure breed purple flower is crossed with pure breed white flower. The pure breed traits are always homozygous in nature.
On crossing white and purple flower, all the progeny have a phenotype of purple flower. In cross reproduction, the progeny inherit one allele from each parent. So, in the progeny, there would be one allele for purple and one for white, but the phenotype is purple, so, it suggest that purple trait masks the effect of white trait. Hence, the purple phenotype is dominant over white phenotype.
The given cross represent the cross between purple (PP) and white (pp) pure breeds.
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.
Answer:
True
Explanation:
Halogens belongs to the seventh group on the periodic table. This group contains the most reactive set of elements that we have. They require just an electron to achieve a noble and stable electronic configuration.
When halogens mostly in form of ChloroFluoroCarbons(CFCs) reaches the atmoshpere, ultraviolet rays release chlorine atoms which easily breaks away an oxygen atom from ozone. Ozone thereby turns into an oxygen gas with two oxygen atoms instead of three. This reaction depletes the ozone layer.
