An endothermic reaction is one in which energy is absorbed. which of the following is an endothermic reaction in terms of latent heat?
a) liquid water changes to water vapor
b) liquid water changes to solid water
c) water vapor changes to solid water
d) water vapor changes to liquid water

A) Liquid water changes to water vapor.

Option 'A' is correct.

Explanation:

An endothermic reaction is a reaction in which large amount of energy is absorbed in the form of heat.

It may be found in two process:

1) Chemical process

2) Physical process.

Examples of endothermic reaction is melting ice etc.

that means liquid water changes to water vapor.

Hence, Option 'A' is correct.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
