Traits are found in what of the DNA?
*Traits as in the colour of your eyes or your blood type*
The allele

Skin is scaly
Has fins instead of external limbs
Has gills

Farmers often use green houses to produce more crop. (crop is what they grow to sell)
Explain in your own words why green houses make more crop?
(Each group may answer differently to get the point.)
Green house can keep the crop more warm year round to have them growing all year, while in the winter it may die.
They can input CO2 which is needed for photosynthesis. With more CO2, they will grow better and faster.
They can add more fertilisers. The fertilisers have extra ions that the plant need to grow faster, stronger, and also used in photosynthesis that they might not get in natural soil.
Can use arificial light. More light, even in the night, can have the plant producing more sugar and making more crop.
Etc...

This is an image of the stomach. What enzymes are found there and what liquid. Explain the function of each.
The enzyme is pepsin and lipase. Pepsin will breakdown protein into amino acids while lipase will break down fats into fatty acid and glycerol.
The juice found in the stomach are gastric juice (hydrochloric acid + enzymes) Its function is to destroy any pathogens and break down food.

Name the part of the female reproductive system that produces oestorgen?
What is its function during puberty?
Oestrogen is produced in the ovary.
During puberty, oestrogen will start the girl's menstrual cycle. It will also start the growth of the girl's hips and breasts.

Plants take in ions from the soil.
The amount of ions in the plant is greater than it is in the soil.
What process does the plant do to take in ions from the soil? Explain these process.
Active Transport
It takes in ions from the soil from low to high concentration. It uses energy by respiration to bring in the ions into the plant by protein carriers on its cell membrane.

Two identical plants are put in to environments.
1. In a hot dry windy desert
2. In a warm moist jungle.
What would happen to these plants if they were not watered for two days?
Plant:
1. It would lose water and become flaccid by transpiration from the heat and the wind.
2. The plant would not lose a lot of water. The water content inside and out of the plant is similar so it would lose less water and keep its turgid pressure.

The following picture is of the human breathing system.
State 2 featured of the alveoli that make them an effective gas exchange surface.
What muscle helps in breathing during inspiration.
1. cell membrane is only one cell thick
2. high surface area for diffusion of gases
3. Good source of ventilation.
etc.
The muscle that helps in ventilation is the diaphragm.

Cell M in the body of a animal contains two set of chromosomes. Each is made of 16 chromosomes.
a) What is the term for the cell that contains two sets of chromosomes?
b) How many chromosomes will be present in a gamete of this anima?
a) diploid
b) in the gamete it will only have 1 set of chromosomes, so 16 chromosomes. (1/2 the total amount of the parent which chromosome number of 32)
Thanks to Chloe and Natasha for pointing out the mistake earlier

Peter Piper picked a peck of pickled peppers, and if Peter Piper picked a peck of pickled peppers, where’s the peck of pickled peppers Peter Piper picked?

DNA is found in the cell.
Which pairs of nucleotides are combines?
If a cell's DNA is mutated, and its base sequence changes, would the cell still be able to produce protein?
Pairs: A-T & C-G
If the DNA base sequence changes, it may affect its ability to create protein. The codes to produce protein are on the DNA and if the codes are not the same, then it won't be able to create that protein.

What is the term when we say the seed starts to grow? What are its requirements needed for this to happen?
Germination is the name for the seed to start to grow.
The requirements for this to happen is availability of water, air, and a warm temperature.

Progesterone and LH are both hormones during the females mestral cycle.
State where progesterone is produced and its role in pregnancy.
Progesterone is produced in the ovary and the placenta during pregnancy.
Its role during pregnancy is keeping the uterus lining thick, filled with blood and nutrients. This is important to keep the unborn baby with lots of nutrients for it to develop.

Two parents are planning on having a child.
The father is colour-blind to red-green colour, and the mother is heterozygous to the gene.
Create a genetic diagram to determine the probability that the offspring of these parents would get a child with this colourblindness gene.
XR = no gene
Xr = gene with colourblindness
Y = male chromosome
Xr Y
Xr XrXr XrY
XR XRXr XRY
There is a 50% change the offspring will have the colourblindness gene

i) Fresh apple juice contains more Vitamin C
ii) anomalous result is a result in the data that doesn't fit a pattern the practical shows.
iii) sample 1, Vitamin C in 'store' apple juice

A species of plant can use self-pollination and cross-pollination.
i) Suggest reasons why this species of plant uses self-pollination rather than cross-pollination.
ii) Discuss the potential effects of only self-pollination, it has on the population of plants.
i) Anything saying that it only requires one parent, it's quick, doesn't take much energy, and have characterics that would be desired.
ii) For a plant only self-pollinating, its population genetic makeup would be the same or very similar. It would be more sensitive to diseases that could wipe-out the population or have it not adapt to environmental changes.

The placenta and umbilical cord transfer substances. For instance, the placenta transfers nutrients and gases from the mother to the unborn baby. The umbilical cord transfers waste like CO2 or urea from the baby to the mother.
It also provides a barrier so pathogens and diseases don't cross to the baby and provides passive immunity.
etc.

Proteins are biological molecules.
Explain how proteins are made in the body.
DNA in the nucleus unravel into an RNA
The RNA copies itself to a mRNA.
This exits the nucleus into the cytoplasm.
It goes to the ribosome, where it will read the mRNA for which sequence of amino acids it will bind.
This binding of repetitive 3 amino acids will form the protein molecule.
