Explanation:
Transfer of energy from one living to another in a food chain is called pyramid energy.
So simply we can energy pyramid shows how much energy passes from one living to another in a food chain.
Food chain always begins with autotrophs i.e. green nature (plants). Which becomes producers.
There are different types of organisms based on food habits and their environment.
Answer:
The regions near the topic receive more sunlight compared to those of the equator.
Foreign invaders have proteins called antigen, which antibodies lock onto to neutralize. The foreign proteins are different from proteins in our own body, so the immune system can recognize them and finally eliminate them.
Answer: 0.18
Explanation:
For the alleles, the percentage distribution of each is 'A' (90% = 0.9)
While 'a' (10% = 0.1)
Hence, 0.9 and 0.1 are the respective frequencies of each allele
Now, apply Hardy-Weinberg Equilibrium equation, where heterozygotes are represented by the 2pq term.
Therefore, the number of heterozygous individuals (Aa) is equal to 2pq which equals
2 × 0.9 × 0.1 = 0.18
Thus, the frequency of heterozygote is 0.18, while the percentage distribution in the population is 18%
