Answer;
Complete
Valence is the number of electrons an atom must gain or lose in order to complete its outer energy level or have a stable octet in its outer shell.
Explanation;
-Valency is the number of electrons that an atom requires to gain or lose to form a complete configuration or an octet configuration.
-Atoms tend to lose or get electrons in order to achieve the electronic arrangement of atoms of the noble gases. An ion is an atom or group of atoms having an overall electrical charge. Atoms gain electrons to form cations (positively charged atom), while other lose to form anions (negatively charged atoms).
Answer:
true
Explanation:
A. Proteins
B. Lipids
C. Nucleic acids
D. Carbohydrates
Enzymes are biomolecules that belong to proteins. They are vital for speeding up chemical reactions in the human body to ensure healthy living.
Enzymes are specialized biomolecules that play a fundamental role in the human body, primarily by speeding up chemical reactions critical for life. These biomolecules belong to the category of Proteins. This is because enzymes are composed of sequences of amino acids, which are the building blocks of proteins.
Unlike lipids, nucleic acids, and carbohydrates, proteins possess the unique ability to function as biological catalysts, reducing the amount of energy required for a reaction and thereby accelerating its rate.

Explanation:
Enzymes are proteins.
Selective breeding ( also called {blank }) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotype traits (blank) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. (blank) animals are known as breeds , normally bred by a professional breeder , while domesticated plants are known as (blank) , cultigens , or cultivars. Two purebred animals of different breeds produce a (blank). Flowers , vegetables and fruit-trees may be bred by amateurs and commercial or no-commercial professionals: major crops are usually the provenance of the professinonals.
Answer Key
Selective breeding also called (artificial selection.) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics.) by choosing which typically animal or plant males and females will _exually reproduce and have offspring together. (Domesticated.) animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as (varieties.) , cultigens, or cultivars. Two purebred animals of different breeds produce a (crossbreed.) . Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals.
