Ques: Answer the following question given this paragraph: A cell with two sets of chromosomes is diploid , referred to as 2n , where n is the number of sets of chromosomes. Most of the cells in a human body are diploid. A cell with one set of chromosomes, such as a gamete, is haploid , referred to as n . Sex cells are haploid. When a haploid sperm ( n ) and a haploid egg ( n ) combine, a diploid zygote will be formed ( 2n ). In short, when a diploid zygote is formed, half of the DNA comes from each parent. Q: A cell with two sets of chromosomes is called a? Choices: - haploid - chloroplasts - biploid - diploid A:
Ans: diploid

Answer the following question given this paragraph: Whales and bats have the trait of echolocation. This is the ability to locate objects in the dark by bouncing sound waves off them. The most recent common ancestor of whales and bats did not have this trait. Apply lesson concepts to explain how the trait evolved in whales and bats. Q: What term is defined as the ability to locate objects in the dark by bouncing sound waves off them. Choices: - morphology - night vision - thermodynamics - echolocation A:
(A).
echolocation
Ques:Answer the following question given this paragraph: When chemicals in solution react, the proper way of writing the chemical formulas of the dissolved ionic compounds is in terms of the dissociated ions, not the complete ionic formula. A complete ionic equation is a chemical equation in which the dissolved ionic compounds are written as separated ions. Solubility rules are very useful in determining which ionic compounds are dissolved and which are not. For example, when NaCl(aq) reacts with AgNO3(aq) in a double-replacement reaction to precipitate AgCl(s) and form NaNO3(aq), the complete ionic equation includes NaCl, AgNO3, and NaNO3 written as separated ions:. Q: A complete ionic equation is a chemical equation in which the dissolved ionic compounds are written as what? Choices: - charged ions - joined ions - realized ions - separated ions A:

Ans:separated ions
Ques: Answer the following question given this paragraph: Nutrients the body needs in relatively small amounts are called micronutrients . They include vitamins and minerals. Vitamins are organic compounds that are needed by the body to function properly. Several vitamins are described in Table below . Vitamins play many roles in good health, ranging from maintaining good vision to helping blood clot. Vitamin B12 is produced by bacteria in the large intestine. Vitamin D is synthesized by the skin when it is exposed to UV light. Most other vitamins must be obtained from foods like those listed in Table below . Q: What is the term for nutrients the body needs in relatively small amounts, including vitamins and minerals? Choices: - minor nutrients - insignificant nutrients - trace nutrients - micronutrients A:
Ans:
micronutrients
