Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...

OL Lab 7: Mendelian Inheritance: From genes to traits Learning Objectives:  Explain how traits are passed on from parents to their offspring and the factors that causes variations.  Apply Mendel’s Laws of Inheritance in color deficiency.  Compare and predict the phenotypes of offspring with given genotypes using Punnett squares.  Analyze dominant and recessive alleles, and how these alleles influence an individual’s biological make-up Our characteristics or traits are de...

Cellular Processes and the Genetic Environment 1. Describe cellular processes and alterations within cellular processes. Movement. Muscle cells can generate forces that produce motion. Muscles that are attached to bones produce limb movements, whereas those that enclose hollow tubes or cavities move or empty contents when they contract. For example, the contraction of smooth muscle cells surrounding blood vessels changes the diameter of the vessels; the contraction of muscles in walls of t...

■ How can the sequence of bases contribute to the diversity among species? - Answer-DIFFERENT SEQUENCES OF BASES MAKE DIFFERENT TRAITS ■ Introns and Exons - Answer-INXONS ARE NOT NEEDED (IN TRASH), EXONS ARE THE PART OF NUCLEOTIDE THAT DO CODE FOR MAKING THE PROTEIN AND ARE READ (ESSENTIAL) ■ What are histones? - Answer-THE PROTEINS DNA WRAPS AROUND, HELPS BUILD SHAPE OF CHROMOSOMES ■ What are the nucleotide bases? - Answer-adenine (A), cytosine (C), guanine (G) and thymine (T). ...

Bio 181 Chapter 13Sex Chromosomes - correct answer X (large) and Y (small) -only the ends of the Y chromosome have regions that are homologous with corresponding regions of x chromosomes SRY Gene - correct answer required for development of testes -sex determining region y protein Ovum - correct answer contains an x Sperm - correct answer can contain an x or y Sex-Linked Gene - correct answer gene located on either sex chromosome -50 to 60 Y-linked genes (found on Y chromosomes) ...

Dominant vs Recessive Genes ANSWER: Genes are either dominant or Recessive: When dominant and recessive genes are paired, the traits of the dominant gene will be present; If 2 recessive genes are paired, the trait portrayed will be recessive. Sex-Linked Inheritence ANSWER: Conditions can either be X-linked or Y-linked Sex-Linked Inheritance: Male Children ANSWER: Always going to be dominant (X,Y) If a male receives an x chromosome with the mutated gene and the y chromosome does...

Advanced Patho HESI Questions and Answers Rated A+ The nurse hears short, high-pitched sounds just before the end of inspiration in the right and left lower lobes when auscultating a client's lungs. How should this finding be recorded? Fine crackles are short, high pitched sounds heard just before the end of inspiration that are the result of rapid equalization of pressure when collapsed alveoli or terminal bronchioles suddenly snap open. The nurse is assessing an older client and determines ...
