B. Subgroups
<span>When constructing a dichotomous key, the first step is to look at the group of objects or organisms and separate them into two groups based on a single distinguishing characteristic. Then continue to separate each of the groups until each object has its own separate set of characteristics.</span>
Air must pass from the back to the front of the pharynx to enter the trachea and food must pass from the front to the back of the esophagus
Answer: C. M. rupestris, M. eastwoodiae, and M. nelsonii; they put more energy into making rooted branches than they put into making nectar and seeds.
Explanation:
In asexual mode of reproduction the plant does not produce gametes. The plant reproduce through vegetative propagation or spore formation. The plant does not produce nectar as no flowers are produced to attract the pollinators.
In sexual mode of reproduction the plant will develop the gametes and flowers will produce the nectar to attract the pollinators.
Thus on the basis of above explaination, C is the correct option. As the plants will invest more energy in making roots which are the organs for vegetative propagation a process of asexual reproduction.
Answer: Option A
Explanation:
In Prokaryotes the the rate of new mutations is much more as compared to the eukaryotes. The rate of accumulation of mutation is slow in case of eukaryote because their generation is long as compared to prokaryotes.
Prokaryotes have short generation time and large population size which enables them to accumulate the mutation quickly.
The machinery is also not that complex when it comes to prokaryotes. Transduction, conjugation and tranposable elements. So, the changes during these processes leads to mutation in the prokaryotes and can be observed quickly due to their small generation.
