Answer:
The correct answer will be option- A
Explanation:
Spores are the reproductive unit produced as a result of sexual reproduction and asexual reproduction in both lower and higher plants.
The plant groups like Fungi, Algae, Bryophytes, Pteridophytes and Gymnosperms produce these spores which provides adaptation as they can be dispersed for the long-distance as well as germinate and form an organism.
The spores are formed by the process of sporogenesis which forms four spores from a diploid structure their meiosis which reduces the genetic material to half and maintain the haploid ploidy number.
Thus, option-A is the correct answer.
The answer is B. 25°C.
A temperature of 25°C can be considered as a room temperature. It is an optimal temperature for the most living beings which cell potential is considered as standard. It is known that at 100°C water boils, so this temperature cannot be standard, cells will degrade at this temperature. Similarly 0°C and –273°C are too cold, water of the cells will freeze, cells will freeze, and cell potential will not be optimal.
That was sir Isaac Newton’s only discover so it is true
Evaporation is the process that requires water to gain heat energy from the environment to turn into gas.
