Food Choices

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
