Answer:
Option D is a correct answer
Explanation:
An adaptation is adapted to suit the environment as every environment is different.
Different environment aids to different kind of adaptations that perfectly suits the animals living there.
The adaptation of an animal living in the desert region will have adaption to work in hot climate. The plant that grows in a desert area have no leaves and broad stem to store water.
The animals that live in the polar regions have thick fur to provide insulation and heat to live in polar region.
B and C is where cell division takes place
Answer:
C. 217
Explanation:
Mendel obtained the phenotypic ratio of 3 dominant: 1 recessive in the F2 generation of a monohybrid cross. According to the given information, inflated pods are dominant over the constricted one.
Let's assume that the allele C is responsible for inflated pods while the recessive allele "c" gives constricted pods. A cross between two pure breeding plants with inflated (CC) and constricted pods (cc) would give all the plants with inflated pods (Cc) in the F1 generation. A cross between two F1 plants would obtain F2 generation in following ratio=3 Inflated: 1 constricted.
Therefore, if 650 plants with inflated pods were obtained in the F2 generation, 217 plants must have constricted pods since 650:217 is almost equal to 3:1.
