Answer:
The correct answer will be option-A
Explanation:
Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.
The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.
In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.
Thus, option-A is the correct answer.

Answer:
E. Mangroves have only one type of root system
Explanation:
Mangrove species are those species of plants found in a saline environment. The soil they are found is usually shallow and swampy (water-logged). They possess characteristics feature that helps them adapt and survie in their habitat.
One of those features is the possession of PNEUMATOPHORES OR BREATHING ROOTS, which is a kind of root system that extends out so that the pores on them can allow the intake of gases directly from the atmosphere.
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
