Expodentially is the correct answer
They have all been formed by sandblasting
Answer:
Genetic variability. (Ans B)
Explanation:
Sexual reproduction is defined as the development of the new gamete, and it involves the characters of both parents, and showing the new characters from the fusion of male, and female gametes. Some characteristic of sexual reproduction are:
1) It is biparental in nature.
2) Gametes are always synthesized.
3) Fertilization occurs.
4) Meiosis and mitosis both involves.
5) New gamete genetically different from parents.
6) Multiplication is not so rapid.
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Answer:
The flowering population is in Hardy Weinberg equilibrium.
Step by Step Explanation:
Total initial population size = 60
As both the populations are homozygous so the frequency of alleles will be,
P = 80/120= 0.66
q = 40/120= 0.33
The predicted frequencies for genotypes once the population has reached Hardy-Weinberg
p2 = 0.4356
2pq= 0.4356
q2 = 0.1089
The number of plants with each type of flower in a papulation of 420 is,
Homozygous dominant= 185
heterozygous= 185
Homozygous recessive= 50
Chi square analysis:
The observed values for red-flowered plants, pink-flowered plants, and white-flowered plants are not significantly different from the expected values predicted by Hardy Weinberg equilibrium.
Phenotype observed(o) expected (e) (o-e)2/e
Red 178 185 0.26
Pink 190 185 0.135
White 52 50 0.08
chi-square = 0.474
With 2 degree of freedom this chi-square gives a p value of 0.7 - 0.8, which is not significant.
