What happens to kidneys when there is too much or too little pottasium
when kidneys don’t work properly, pottasium builds up and becomes harmful to body
2
How does urine travel to bladder
thin tubes of muscle that connect kidneys to bladder and carries urine there
3
What would happen if kidneys did not excrete salt
the sodium would collect in bloodstream, which can lead to problems like high blood sugar
4
What substances are absorbed into bloodstream ?
water, salt and minerals
5
What 2 substances does the kidney NOT filter
blood cells and larder protein molecules
6
What happens if the kidney ingests excessive amount of vitamins
they can make crystals that don’t break down and block urine flow, damaging kidneys
7
What is urea
carbamide; organic compound with the chemical formula CO(NH2)2, simplest form of carbamic acid
8
What are casts
tiny tube like particles that can be found when urine is examined under amnieriscooe
9
Because there is no light, organisms rely on a unique process to produce energy molecules like glucose. The process is called
chemosynthesis
10
One necessary reactant/substrate for chemosynthesis would be
oxygen
11
The energy rich molecule in the cell is formed by the conversion of
ADP to ATP
12
The production of oxygen for our atmosphere depends upon plants breaking down
carrion dioxide in the light reactions
13
The process of photosynthesis recycles the products of respiration. The reactants of photosynthesis are
carbion dioxcide and water
14
The transport of an electron through the respiratory chain cause the electron to
lose energy resulting from ATP
15
During the process of photosynthesis, light energy is used directly in the
formation of ATP
16
The final electron acceptor in glycolysis when oxygen is not present in
pyruvate acid
17
The three energy containing compounds produced during kerbs cycle are
ATP, FADH and NADH
18
Complete the chart in the order; DECOMPOSITION, BURNING FORESTS, PHOTSY, CELLULAR RESPIRATION, With 1 being adding oxygen into biosphere, and 2 being adding carbon dioxcide to our biosphere
2,2,1,2
19
A typical food chain may have three, four or five trohpic levels. Why is five the greatest number?
there is insufficient energy for a 6th level to be sustained
20
In a food chain that contains a hawk, wheatgrass, and grasshopper. In that order they are known as;
territory consumer, producer, primary consumer
21
What does pyruvate acid contain ?
carboxylic acid and ketone functional groups
22
What are the 3 types of circulation
systematic, poly monarch and portal
23
Which T cell helps destroy infected cells?
cytotoxic T cells
24
Which T cells activate B cells to secrete antibodies and macrophages to destroy ingested microbes
helper T cells
25
Which T cell blocks the actions of some other types of lymphocytes to keep immune system from becoming over active
suppressor T cells
26
Which T cell collects information on antigens to identify invasion in the future
memory T cells
27
What is a light dependant reaction
reaction that happens in thylakoid membrane of chloroplast and occurs in presence of sunlight
28
Definition of secondary predator
predator that predates on primary consumers
29
Define primary consumer
organism that eats grass and plants
30
What is the order of the predator pyramid
tertiary, secondary, primary, primary producer, soil decomposition
31
What enzyme is found in the mouth and how does it work
salivatiry amylase, breaks down starches into sugars , slipase, converts triglyceride into partial glycerides
32
What enzymes are in the pancreas and what are their functions
pancreatic amylase; turns starch into glucose , trypisin; breaks down protein into amino acids , pancreatic lipase; turns lipids into fatty acids and glycerol
