1

Conjugation

Occurs in Gram-Negative Bacteria, requires F factor that is on a extragenomic plasmid

2

Conjugation

3

Transformation

Bacteria take up DNA from their surroundings in the the media in which they are immersed

4

Tranduction

Gene transfer by a virus

5

Translocation

Describes movement from one place to another (genes on chromosomes, proteins in cells, sap in a tree)

6

7

Negative Pressure

Accomplishes the inflation of the lungs; a pressure lower than atm pressure is generated within the alveolar sacs during contraction of the diaphragm and external intercostal muscles

8

Negative Pressure

Accomplishes the inflation of the lungs; a pressure lower than atm pressure is generated within the alveolar sacs during contraction of the diaphragm and external intercostal muscles

9

Control of heart rate, muscle coordination and appetite is maintained by

Brain Stem, Cerebellum and Hypothalamus

10

Pain-Perception Pathway

To add the sensation of pain to a reflex pathway, neurons must be added at the sensory end

11

Difference in Anaphase

Mitosis = sister chromatids are pulled apart at the centromeres, each becoming an independent chromosome
Meiosis I = homologous pairs of chromosomes are separated into the two daughter cells but they are still joined at the centromere

13

Deleterious Genes

Those which are eliminated through natural selection

14

Type of Tissue that lines the Bowman

Simple Squamous Epithelium

15

Type of Tissue that lines the Bowman

Simple Squamous Epithelium

16

Increase in BP effect on the kidney

Increases the flow of fluid through the kidney and decrease water reabsorption

17

Increase in BP effect on the kidney

Increases the flow of fluid through the kidney and decrease water reabsorption

18

Two factors that normally determine the BP

Cardiac Output (stroke volume x heart rate) & Resistance to Blood flow

19

What is BP equal to?

Total peripheral resistance x cardiac output, analogous to ohm's law

20

What is BP equal to?

Total peripheral resistance x cardiac output, analogous to ohm's law

21

Vasoconstriction

Restricts blood flow to an organ and can increase BP whereas vasodilation has the opposite effect; important in a hemorrhage

23

Functions of Liver

Absorption of fats in the small intestine, production of bile, detoxification of drugs/poisons

24

25

What can cross the walls of the blood vessels?

Water molecules and other small molecules; plasma proteins cannot

26

What can cross the walls of the blood vessels?

Water molecules and other small molecules; plasma proteins cannot

27

Edema

Increased fluid in body tissues can be due to decrease in plasma protein levels

28

Increase in the level of plasma protein causes

Fluid to enter the bloodstream due to influx of tissue fluid (which contains solutes)

29

Increase in the level of plasma protein causes

Fluid to enter the bloodstream due to influx of tissue fluid (which contains solutes)

30

Insufficient Vitamin D Activity

Reduces the ability of the body to absorb ingested calcium from the small intestine

31

Insufficient Vitamin D Activity

Reduces the ability of the body to absorb ingested calcium from the small intestine

32

What conditions lead to an increase in calcitonin levels?

High levels of calcium in the plasma

33

What conditions lead to an increase in calcitonin levels?

High levels of calcium in the plasma

34

What would be the result of removal of the parathyroid gland?

Severe neural and muscular problems due to deficiency of calcium in the plasma

35

Aldosterone Deficiency

Results in lower sodium reabsorption into the bloodstream; leading in decreased blood volume and this would also decrease blood pressure

36

Organs involved in the menstrual cycle

Hypothalamus-Pituitary-Ovary

37

Organs involved in the menstrual cycle

Hypothalamus-Pituitary-Ovary

38

Growth of long bones

Occurs via endochrondral ossification so there will be cartilaginous areas in long bones of children

Vasodilation (Method of heat transfer)

Radiation
