Ig it’s true. The emission of gramma rays results in the loss of energy.
Answer:
Explanation:
From the question, the total population = 171 i.e (80+71+21)
Genetic frequency therefore; BB = 71/171 = 0.42
Bb = 80/171 = 0.47
bb = 20/171 = 0.12
Allele frequency therefore;
Allele B = 0.42+(0.50×0.47) = 0.66
Allele b = (0.50×0.47)+0.12 = 0.36
Note all values were rounded up to two significant figures
Answer:
Bottle neck effect
Explanation:
Bottle neck effect in Biology, refers to a phenomenon in which some environmental factors (droughts, disease, fires, floods, earthquakes or famine etc) or man made causes (like hunting) lead to a severe reduction in the size of population of a certain living organism.
This type of events not only lower the variation in the population genepool causing lack of genetic diversity, but also reduce the overall size of population.
The mentioned scenario in the question is an example of Bottleneck effect in which genetic diversity of the pigeon population was decreased due to man made activity i.e Hunting.

Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
