How do you figure out the magnification of the microscope
Eyepiece X objective lense
In photosynthesis, plants change this into chemical energy that plants and animals can use as food.
Sunlight
Ribosomes consist of ______
rRNA and proteins
True or false: Antibiotics act only on bacteria.
True
What is a pioneer species?
a species that first colonize new habitats after a disturbance
Which part of the microscope holds the specimen slide in place?
Stage clips
cellular respiration takes place in the mitochondria. Where in the human body do you expect to find the most amount of mitochondria?
Muscle cells
During transcription, a strand of ____________ is made to complement a strand of DNA
mRNA
What is the first stage of mitosis
Prophase
The bases on the mRNA strand are called _____
codons
What is an abiotic factor and give an example
What is a biotic factor and give an example
non living - water, sunlight, rocks
living- animals, plants, humans
What are the reactants and products of photosynthesis
Reactants: CO2 and H2O (sunlight )
Products: C6H12O6 and O2
Which base sequence is the complementary DNA for GCATAC?
CGTATG
Which type of reproduction leads to increased genetic variation on a population?
Sexual reproduction
Through transpiration, water is released back into the atmosphere through the plant’s __.
Leaves
What is the main function of leaves?
Provides a place for photosynthesis to occur
What are the reactants and products of cellular respiration?
Reactants: O2 and C6H12O6
Products: Co2 and H20
What is the probability of getting a Ff heterozygous offspring from a cross of homozygous FF and ff parents?
100%
What causes blood pressure?
contraction of the ventricles in the heart
_______ is a symbiotic relationship in which one species benefits while the other species is not affected.
Commensalism
Which requirement MUST be met in order for a scientific statement to be accepted as a theory?
The statement relies on many supporting pieces of evidence.
Explain how plants and animals maintain the flow of matter through ecosystems? provide specific examples such as products and reactants
plants take the suns energy and convert it into glucose. this glucose is provided to animals through the form of food. the animals then use that glucose to make energy or ATP. animals then give off the products of H2O and CO2, both necessary for a plant to undergo photosynthesis
Where does DNA replication occur
Nucleus
Sexual reproduction is to meiosis as asexual reproduction is to _________________
Mitosis
What is a difference between facilitated diffusion and active transport?
Active transport uses ATP and moves substances against the concentration gradient
