Polar ice caps are the coldest place on the earth. The temperature here is very low, always below 0 degree Celsius on an average.
Polar ice caps has no vegetation because:
1. Ice is present on the ground permanently.
2. Water present in the soil remains frozen and thus, unavailable for plants to grow.
3. Cold weather that do not support vegetation.
Chlorophyll<span> and the photosynthesis process are inside an organelle called a </span>chloroplast<span>. </span>Chlorophyll<span> is also the pigment that gives plants their green color. </span>
Answer:
Yes, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg.
Explanation:
Here ,
![f(A)= p=0.575](https://tex.z-dn.net/?f=f%28A%29%3D%20p%3D0.575)
![f(B)= q=0.425](https://tex.z-dn.net/?f=f%28B%29%3D%20q%3D0.425)
As per the first principle of hardy Weinberg, the sum of all the alleles at the locus must be equal to 1.
Thus,
![p+q=1\\0.575+0.425 = 1\\1=1\\](https://tex.z-dn.net/?f=p%2Bq%3D1%5C%5C0.575%2B0.425%20%3D%201%5C%5C1%3D1%5C%5C)
Also, as per the second equation of Hardy Weinberg's equation-
![p^{2} + q^{2} +2pq =1](https://tex.z-dn.net/?f=p%5E%7B2%7D%20%2B%20q%5E%7B2%7D%20%2B2pq%20%3D1)
![(0.575)^2+2(0.575)(0.425)+(0.425)^2=1\\0.3306+ 0.48875+ 0.180625=1\\1=1\\](https://tex.z-dn.net/?f=%280.575%29%5E2%2B2%280.575%29%280.425%29%2B%280.425%29%5E2%3D1%5C%5C0.3306%2B%200.48875%2B%200.180625%3D1%5C%5C1%3D1%5C%5C)
Hence, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg
Answer:
The complement system or complement cascade is an essential part immune system that increases the ability of the immune cells such as phagocytic cells and antibodies to kill and remove foreign bodies such as microbes and removes the damaged or infected from the cells of an infected organism.
The complement system utilizes the classic pathway to destroy cell walls or membrane of antigen or microbes, however, it sometimes also use alternate pathway for certain organism
Large numbers of activated complement proteins are produced by the complement system that binds and, opsonizing microbes for internalization by phagocytes having receptors for a complement. It is important for innate defense
