what is photosynthesis and cellular Respiration?
photosynthesis is the process to make food for plants and cellular respiration is the process for breaking down sugar made from photosynthesis.
100
function of the stigma
to receive pollen
100
what are the parts of the nucleotide found in nucleic acid?
Phosphate group, Deoxyribose Sugar, and nitrogenous Base
200
someone gets stung by a Bee and the person is in pain. which systems are working together?
integumentary, nervous, muscular, and skeletal.
200
without this part of the enzyme, the substrate can't bind preventing the chemical process from proceeding.
active site
200
chemical formula for photosynthesis
CO2 + H2O + light----> C6H12O6 + O2
200
the parts of stamen
anther and fillament
200
if DNA can't leave the nucleus, How does the genetic code get out of the nucleus?
mRNA transcription, mRNA transcribes the genetic code and carries it outside the nucleus into cytoplasm
300
what would happen to the body if it didn't have a skeletal system? what would be affected?
no structure for the body and no red-blood cell formations.
300
why does enzyme activity lower at very high temperatures and why does that matter to the enyme?
it denatures and causes the enzyme to change shape preventing substrate to enzyme binding
300
chemical formula for cellular respiration
C6H12O6 +6O2----->6CO2 +6H2O
300
a plant grows normally until it touches a pole, then grows around it, which tropism is invovled?
thigmotropism
300
what are the codons that starts the mRNA sequence and stops the mRNA sequence?
AUG=starts
UAA/UGA/UAG= stops

A marathon runner is halfway through a hot, humid race. She stops sweating, her core body temperature spikes dangerously high, her muscles begin to cramp severely, and she feels dizzy and confused. what systems are being affected?
Integumentary, circulatory, muscular, and nervous.
400
someone is lactose intolerant, which enzyme is missing?
Lactase
400
where does photosynthesis and cellular respiration take place?
photosynthesis happens in chloroplast and cellular respiration happens in mitochondria.
400
if there were no phloem, how would that affect the entire plant?
there would be no nutrient or mineral absorption through roots.
400
if there is a missing amino acid codon or extra amino acid codon, or perhaps a substituded codon; what happens to the entire DNA sequence?
the sequence causes a mutation.
500
someone touches a hot pan and quickly pulls away, what are 2 body systems are NOT directly involved?
urinary and reproductive
500
after reaching optimal temperature, what happens to the enzyme activity and what is the temperature interval that the enzyme changes?
enzyme activity lowers from 400 to 600 Celsius.
500
how is photosynthesis and cellular respiration related?
the reactant for photosynthesis is the product of cellular respiration, and the reactants for cellular respiration are the products of photosynthesis. therefore, it is a constant loop.
500
if there wasn't a stem, how would that affect the plant?
no xylem or phloem, so no nutrients or water causing the plant to wither and die.
500
original sequence: CTGGAG
complementary sequence: CTGGGG
what happened here? what kind of effect does it have?
substitution mutation
