Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.
Sedimentary rocks are formed because of overburden pressure
Sexual reproduction produces genetically different offsprings which do possess variations, hence better chance to survive in the environment.
Option C
<h3><u>Explanation:</u></h3>
Sexual reproduction is the process of reproduction where there's a fusion of gametes from a male and female of the same species, resulting in a zygote and eventually an offspring. Sexual reproduction is very advanced type of reproduction which is very expensive for an organism. Much of the energy of the organism is spent to produce gametes and other necessary processes for reproduction.
Gametes of the sexual reproduction is produced mainly by means of meiotic cell division. This involves crossing over and chaismata formation which helps in genetic variations in the offspring. These variations help the species to survive unknown changes in environment, and helps to adapt quickly lessening the chances of extinction. So sexual reproduction has modified various times in different groups of species.
