germ cell
- any biological cell that gives rise to the gametes of an organism that reproduces sexually.
inflammation
- the movement of leukocytes into the mucosal tissue
- leukocytes gravitate toward inflammation
blood plasma and lymph are examples of
- extracellular fluid
where is hemoglobin carried?
- in the red blood cells
- not found in plasma
why is water lost through the skin
- as a means to keep the body at normal temperatures
what does lipases ability to catalyze the hydrolysis of fats tell us?
- that they have similar chemical linkages
what is inflation of the lungs accomplished by?
- negative pressure pumping action
genes outside of the chromosome are
- self replicating
what is the arrangement of all nucleic acids?
- linear arrangement
what are the polar bodies cast off with?
- the cytoplasm
what is extremely sensitive to the timing of mRNA turnover
- the coordination of cell differentiation
myoglobin
- the substance that holds oxygen in the muscles and organs
characteristic of eukaryotes versus prokaryotes
- contain membrane bound organelles such as mitochondria
big difference between mitosis and meiosis I
- the centromeres split in mitosis
increased blood pressure affects what?
- increased glomerular filtration rate
two factors that determine blood pressure
- cardiac output
- resistance to blood flow
blood pressure during a hemorrhage
- the narrowing of the blood vessel restricts blood flow to an organ and can increase blood pressure
what increase blood flow to the muscle during exercise
- vasodilation
if you have an increase in albumin in the blood, what will happen
- water will have to flow into the bloodstream to establish equilibrium.
how can the liver partially regenerate after illness or damage
- through mitosis
between human and bacterial cells, which have cell walls?
- only bacterial cells
bacterial chromosomes are
- circular
human chromosomes are
- linear
what determines a species
- the ability to successfully breed and produce fertile offspring.
how does the double stranded daughter molecule compare to the parent molecule?
- exact duplicate
where does transcription of DNA to RNA take place
- in the nucleus
nervous tissue arises from what
- ectoderm
any disruption of mitochondria will affect ATP production how?
- will decrease ATP production
where is glycogen made, stored, and broken down?
- the liver
which muscles contain striated muscle fibers?
- skeletal and cardiac
is cell differentiation an all or none phenomenon?
- no!
vasodilation
- the walls of the blood vessels relax, allowing more blood to enter the area
- allows heat to escape from the surface of the body into the environment.
radiation
- vasodilation
how do long bones grow?
- via endochondral ossification, which requires cartilaginous growth plates at the ends of long bones.
how do sweat glands work?
- the sweat glands secrete onto the surface of the skin through channels continuous with the most superficial layer of the skin, the epidermis
