Ques: Q: What are chromosomes in the same pair called? Read this paragraph and choose the correct option from the provided answers: In sexually reproducing species, chromosomes are present in cells in pairs. Chromosomes in the same pair are called homologous chromosomes. They have the same genes at the same loci. These may be the same or different alleles. During meiosis, when gametes are produced, homologous chromosomes separate. They go to different gametes. Thus, the alleles for each gene also go to different gametes. Choices: - homogeneous chromosomes - regulated chromosomes - reversible chromosomes - homologous chromosomes A:
Ans: homologous chromosomes

Ques: Q: Electric generators convert what type of energy to electric energy? Read this paragraph and choose the correct option from the provided answers: Electric generators convert mechanical energy to electric energy. The generator consists of some number of wire loops wrapped around an iron core and placed in a strong magnetic field. The loops of wire and the iron core are called the armature . The armature is mounted so that it can rotate freely inside the magnetic field. Mechanical energy is used to spin the armature in the field so that the wire loops cut across the field and produce electric current. The of this current is calculated by . Choices: - electromagnetic energy - thermodynamic energy - fluid energy - mechanical energy A:
Ans: mechanical energy

Ques: Q: All atoms have equal numbers of what two particles? Read this paragraph and choose the correct option from the provided answers: Electrons are one of three main types of particles that make up the atom. They are extremely small and have an electric charge of -1. All atoms have the same number of electrons as protons. Choices: - nuclei and neutrons - photons and protons - electrons and neutrons - electrons and protons A:
Ans: electrons and protons

Ques: Q: What are broken down during digestion to provide the amino acids needed for protein synthesis? Read this paragraph and choose the correct option from the provided answers: Dietary proteins are broken down during digestion to provide the amino acids needed for protein synthesis. Any extra proteins in the diet not needed for this purpose are used for energy or stored as fat. One gram of proteins provides 4 Calories of energy. Eating protein provides the amino acids for your cells to produce your own antibodies, muscle fibers and enzymes (as well as many other types of proteins). Choices: - sugars - carbohydrates - metabolytes - dietary proteins A:
Ans:
dietary proteins
