Answer:
Pollination →Fertilisation → seed formation → dispersal of seed → Germination
Explanation:
This is the correct sequence of events in the reproduction of flowering plants.
Option A, B, D are only applicable for steroid hormones ( hydrophobic)
So the answer is C
form cell membrane
Explanation:
It provides barriers in cellular membranes to protect the cell , and they make barriers for the organelles with in those cells. It work to provide pathways for various substance across membranes
The right answer is C) vector
In molecular biology and genetic engineering, vectors are DNA molecules that allow the propagation of sequences of interest. These are chimeric DNA molecules such as plasmids or artificial bacterial chromosomes, containing an origin of replication and one or more genetic markers. The origin of replication allows the maintenance of the vector in the target cell during generations.
Answer:
The correct answer will be option-B
Explanation:
The data collected on the bacterial species in the Yellowstone national park involved:
1. habitat characteristics
2.DNA of bacteria from each population
3. compared with other species of the park
Based on these features, the biologist could apply all the types of species concept like ecological species concept which allows the study of the species from the same niche.
Also, they compared the DNA of the species of the bacteria and compared them which allows to trace the evolutionary patterns and showing the phylogenetic relationship.
Since bacteria do not reproduce by the sexual reproduction, therefore, a biologist cannot apply the biological species concept which states that species can be called species which can reproduce only with the closely rated species only or the individual of the same species.
Thus, Option-B is the correct answer.
