Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
Number of types of bread for making sandwich = 2
Number of types of meat for making sandwich = 3
Number of types of cheese for making sandwich = 2
Then
Number of different sandwiches that can be made = 2 * 3* 2
= 12 sandwiches
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option.
This is an example of co-evolution.
<u>Explanation:</u>
In co-evolution one species or a number of species evolve according to the changes in another species. Here the evolution of the beak of humming bird according to the shape of Ossifloramixta flower is an example of co-evolution. Co-evolution is common in the nature.
Bees, insects and butterflies commonly co evolve with the flower plants and vice versa. Co-evolution is of two types. The first type is specific co – evolution where only two parties are involved in co-evolution. In the second type of co-evolution namely diffused co-evolution many species evolve in response to specific traits in a species.
