ANSWERS GRADED A+
◍ Cellular respiration equation.
Answer: C6H12O6+6O2---> 6CO2+6H2O+ATPC6H12O6=
glucose6O2=Oxygen6CO2= Carbon dioxide6H2O= waterATP =energy
◍ phototropism.
Answer: growth is directional toward the sun
◍ Posterior.
Answer: Directional term meaning toward the back
◍ what does 2n mean.
Answer: means the cell has 2 copies of its chromosomes
◍ during which phase of meiosis do the homologous chromosomes pair
together to form the synaptonemal complex.
Answer: prophase 1
◍ the hydrophobic tails.
Answer: face inward hiding away from the water
◍ translation is the process of.
Answer: making protein from mRNA
◍ process of photosynthesis.
Answer: carbon dioxide- water- sun light- glucose- oxygen
◍ how do plants produce fruit.
Answer: -fruits are products of plant fertilization-flower holds the
reproductive part of the plant-stamen is the male part of the flower- contains
pollen-pollen contains the male gametes-female part of plant is called the
, pistil (or carpel)- has the female gamete the ovule
◍ how do water molcules travel from the root of the plant to the leaves.
Answer: through a process called cohesion and adhesion
◍ `anaphase.
Answer: duplicated chromosomes seperate and are pulled to the opposite
poles of the cells
◍ which of the following is a product from the light -independent reactions
(calvin Cycle) in photosynthesis.
Answer: glucose (C6H12O6)
◍ Distal.
Answer: Directional term that refers to farther away from the point of
attachment of an extremity to the trunk.
◍ which type of lipid is associated with the development of cardiovasular
disease.
Answer: saturated fats
◍ Plasma membrane- Eukaryotic cell.
Answer: is semipermeable-forms a boundary around the cell-regulates entry
and exit
◍ Smooth ER.
Answer: makes lipids
◍ what is tropism.
Answer: the turning of all or part of an organism in a particular direction in
response to an external stimulus.
◍ meiosis 2.
Answer: separates the duplicated X shaped chromosomes into 4 daughter
cells- they have 1/2 the number of chromosomes compared to parent cell-
daughter cells are genetically different compared to parent cell
◍ whats happening during translation.
Answer: mRNA copy of the gene we made in the transcription process,
, leaves the nucleus and goes to the cytoplasm. -in order to read and translate
the mRNA copy we need ribosomes. -in the cytoplasm the ribosome will
read the mRNA copy and translate that mRNA copy into a protein
◍ mitosis end result is.
Answer: 2 haploid daughter cells
◍ The NADH carry 2 important things for the Electron Transport chain to
work.
Answer: electrons and hydrogen ions (H+)
◍ Central Dogma and gene expression.
Answer: step 1. DNa is self replicating: 2. DNA transcribed into RNA3.
RNA translated into a protein- mRNA since it has the message or
instructions on how to make a protein
◍ what are somatic cells.
Answer: the cells that make up the body- like skin cells
◍ what are proteins.
Answer: -macromolecule-vital to living cells-help cells in metabolism-help
cells maintain their structurecan perform chemical reactions inside the cell-
called enzymes-polymers of 20 molecules called amino acids-largest of
biological molecules
◍ nervous system.
Answer: The nervous system consists of the brain, the spinal cord, and the
nerves
◍ what is the purpose of cellular respiration.
Answer: to convert the energy stored in our food into cellular energy
(ATP)-also known as "Aerobic respiration"- this reaction uses oxygen
◍ in covalent bonds the electrons are.
Answer: not shared equally
◍ the expression of proteins make us who we are as individuals.
Answer: these traits give us color, eye color, height and hair color
, ◍ Medial.
Answer: Directional term meaning toward the midline.
◍ Amino acids are held together by.
Answer: peptide bonds
◍ urinary system.
Answer: The urinary system consists of two kidneys, two ureters, a urinary
bladder, and the urethra. The kidneys filter the blood. The ureters are tubes
that transport urine to the urinary bladder where urine is stored before
urination through the urethra to the outside
◍ what are nucleotides.
Answer: monomers for nucleic acids
◍ which organelle converts food into energy to produce ATP.
Answer: Mitochondria
◍ what do platelets do.
Answer: its involved in clotting our blood
◍ what is active transport.
Answer: when a cell is trying to bring in a molecule against the
concentration gradient (going against the flow)-the cell uses energy in the
form of ATP-moving from Low concentration outside cell to High
concentration inside the cell
◍ where does translation occur.
Answer: cytoplasm
◍ all types of lipids are composed of.
Answer: elements :carbon, hydrogen, oxygen
◍ when water is slpit apart it releases.
Answer: oxygen electronshydrogen ions
◍ when water is plentiful the guard cells are.
Answer: relaxed and the stomata opened
