Biological systems rely on intricate mechanisms to maintain homeostasis and drive essential processes. Metabolic pathways, including the conversion of glucose and oxygen into carbon dioxide, water, and energy, are fundamental to cellular function.
Polar bears working harder: Learn/ Connection/ Question
Obesity is a big problem for our sustainability right now as it effects a massive amount of people and it simply is not healthy for people's minds and bodies
Very possible, with more people and less food to go around healthier options may become more expensive
Genetically engineering plants
Genetically engineering food
More food must be produced and scientists can certainly find a way to help with that
Sustainability becomes harder as the demand for everything is more
Population Dynamics
The production of estrogen in the follicular phase and ovulation and both estrogen and progesterone in the luteal phase
The production of sperm, testosterone and inhibin
puberty and the release of LH and FSH
Reproductive feedback loops
The hypothalamus in the brain
They use the build up of potential energy with movement to tell the pituitary glands to release a hormone when the nerve is stimulated.
Nerve cells
A mechanism that keeps the system hovering around its normal all the time
A mechanism that takes the system farther away its normal
A reaction to a stimulus, like you being cold outside so your body sends out a signal in the form of hormones to try and increase your body temperature
Positive and negative feedback loops
They control the regulation of systems in our bodies
Feedback loops
Homeostasis
Partly, DNA replication is semi conservative so they would keep one of their original strands and one new replicated strand. The offspring would also get a semi conservative set of DNA strands
Similar to transcription but the DNA is being copied instead with the help of DNA polymerase, helicase, and primers to copy both sides of the DNA
DNA replication
Nonsense, missense, silent, frameshift, no frame shift
Mutations
Proteins are made because they are the building blocks of our body, making everything. while the genetic code codes for traits in the protons like eye color or hair color. So your genetic code decides everything about you.
Till the tRNA reaches a stop codon that tells it that this is all the instructions for this protein
tRNA which attach to the mRNA to take the code of nucleic acids and change that into a protein
The ribsome
Making mRNA into proteins
Translation
The template strand which is opposite to what it is actually copying; the coding strand
RNA transcript
RNA polymerase to open up the DNA
The copying of DNA to mRNA so that it can be taken out of the nucleus to form proteins
Transcription
Molecular Genetics
Through the phospholipid bilayer or transport proteins depending if the chemical is polar or nonpolar and if they are small
Proteins, phospholipids and cholesterol
chemicals need to be able to move in and out of a cells membrane for the cell to carry out some or its processes
Cell membranes
Hydroxyl, carboxylic, carbonyl, sulfhydryl, amine, or a phosphate group
solubility, melting point, boiling point
Determining the properties of a compound
Functional groups
The instructions to construct the proteins in our bodies
DNA and RNA
Nucleic acids
DNA
mRNA
Peptide bonds
Amino acids
Fatty acids
Steroids, phospholipids, triglycerides
