What are centrioles
involved in spindle organization and are not bound by a membrane.
-animals have a pair of centrioles in the centrosome region.
-plant cells do not have centrioles
describe excretion in Authropods
Nitrogen in form of Uric acid crystals accumulates in Malphigian tubules with mineral salts and then are transported to intestine with solid waste.
What is amylase
hydrolyzes starch to maltose (disaccharide).
Typical of the open sees
What is Curare?
drugs that block the post-synatic acetylcholine receptors
leads to paralysis
What are releaser pharamones?
Trigger a reversible change in recipient.
(i.e. sex attractants; alarm or defensive substances)
: female silkworms secrete powerful attracting pheromones.
What are Helper T Cells?
When activated- secrete cytokines that promote the response of B cells (humoral response) and T cells (cell mediated response) to antigens.
Function of Ligaments
the time between stimulation and the onset of contraction.
(Follicle Stimulating Hormone)
In females- causes maturation of ovarian follicles which begin secreting estrogen.
In males- maturation of seminiferous tubules and sperm production.
-respond to high intensity illumination
-sensitive to color
-3 pigments absorbs red, green, and blue
Villi walls absorb these.
amino acids and monosaccharides (both actively absorbed)
Diaphragm contracts and flattens
External intercostal muscles contract- pushing the rib cage and chest wall up and out. Increasing volume and decreasing pressure.
Don't Jump In
1) duaodenum- most digestion occurs here (secretion also).
Gonadotropin Releasing Hormone
stimulate or inhibit the secretion of the anterior pituitary.
Releasing Hormones are secreted into the hypothalamic-hypophyseal portal system.
Blood from the capillay in hypothalamus flows through a portal vein to Anterior Pituitary.
region on continental shelf
ocean up to 600 ft. deep
can extend 100's of miles off shore.
Hold together the backbone of DNA.
Order of Synapse in the Eye
Photoreceptors-biploar cells-ganglion cells
Axons of the ganglion cells bundle to form the optic nerve.
Pumps 3 Na+ out of cell for every 2 K+ it transports in
When fragments of a bacterial genome became packaged into viral progeny. These virions then infect other bacteria and introduce new genetic information.
cofactors which bind to the enzymes by strong covalent bonds.
The fraction of blood containing a wide variety of antibodies.
Can be used to confer temporary protection.
Yellow Bone Marrow
inactive and infiltrated by adipose tissue.
Swelling along lymph vessels containing phagocytic cells (leukocytes) that filter the lymph
Secreted by intermed lobe of pituitary
Role unknown in humans
In Frogs- causes darkening of skin.
