1. The correct answer is alcoholic fermentation.
Alcoholic fermentation, also known as ethanol fermentation, refers to a biological procedure that transforms sugars, like fructose, glucose, and sucrose into cellular energy, generating carbon dioxide and ethanol and the by-products.
2. A scientific theory refers to a well-substantiated illustration of certain features of the natural world, on the basis of the body of facts, which have been spontaneously confirmed via experiment and observation. Thus, the statement, that it has the same meaning in science as it does in daily life is incorrect.
3. The correct answer is mutualism.
Mutualism refers to a symbiotic association in which both the species benefit.
4. The correct answer is ATP.
ATP refers to the biochemical manner to use and store energy. It is in fact, utilized by every cell of the body as the source of energy, which maintains everything.
The genetic code is considered universal because the same four nucleotide bases are used by all known organisms

The Gymnosperms and Angiosperms are groups of plants with seed, which means that they don’ t necessary acquire water for fertilization. These groups have made adaptations for sexual reproduction on dry land.
1) Gymnosperms (plants with the seeds are not enclosed in an ovary) have developed over the course of its evolution, structures that solved the main limitations present in the Pteridophytes in relation to sexual reproduction, in the terrestrial environment. The main changes that happened as an evolutionary adaptation to dry land are those on the seeds and pollen. The advantages of the seeds are: the storage tissue which sustains growth and a protective coat of the seeds. Seed is enveloped with the layers of hardened tissue which prevents desiccation. This is what frees reproduction from the need for a constant supply of water. <span>The sperm (male gamete) of gymnosperms</span> is enclosed in a pollen grain. Thi structure is protected from desiccation and can reach the female organs without dependence on water. Gymnosperms also developed structures called cupules to enclose and protect the ovule (the female gametophyte) which will develop into a seed upon fertilization.
2) Angiosperms are a group of plants which protect their seeds within an ovary called a fruit. Angiosperms have special evolutionary adaptations. For example, they produce their gametes in separate organs, usually in a flower, so the fertilization and embryo development takes place inside an anatomical structure. That provides a stable system of sexual reproduction largely sheltered from environmental fluctuations like water need.
