gene mutation and crispr are super interesting and current but are common topics for EPQ! Would recommend another one of your options but make sure to include up to date information and recent developments in the area.

Fats molecules are too large to be absorbed into the blood stream inside the tiny capillaries which would get clogged by them.

Variation is differences between individuals of the same species There are two types of variation 1) Genetic/Natural variation 2) Envionmental variation Examples of genetic variation include: -Eye colour -Skin colour -Blood group -Inherited disorders Examples of environmental variation is as follows: -Weather -Diet -Location in the world

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration in order to provide the energy needed for activ... more

Yes the pulmonary valve. It opens to allow blood to be pumped from the right ventricle to the lungs (through the pulmonary artery), where it will receive oxygen. It's purpose is to prevent the back flow of blood from the pulmonary artery to the right ventricle.

Make a list of the cell organelles and their function and what they look like. Nucleus : storage of DNA Mitochondria : Energy Production Smooth Endoplasmic Reticulum (SER): Lipid production ; Detoxification Rough Endoplasmic Reticulum (RER) : Protein production, particularly for exocytosis Golgi Apparatus : Protein modification Peroxisome : Lipid destruction ... Contains oxidation enzy... more

If you think about the equation for respiration (C6H12O6 +6 O2 = 6 H2O + 6 CO2) the gases involved are Oxygen and carbon dioxide. This means there will be a slight decrease in oxygen level and slight increase in carbon dioxide level, everything else will remain the same.

It’s always good to understand the alternative to this question also, passive immunity. Passive immunity is that which is acquired from a different person i.e. an unborn foetus acquired immunity to whooping cough after the mother has the pertussis vaccination at around 28 weeks of pregnancy, and again post birth through breastfeeding. If the mother is exposed to a pathogen her body will make anti... more

Chemical bonds are like two people who are married. It will take a lot more energy (and money) to break them apart. And if they do break apart, they are never the same. Intermolecular bonds are like people who are dating. They are not really committed to each other and it takes less energy to break them apart, and they are pretty much the same when they break apart and will easily for new bonds.... more

Good evening Princeval, I would like to add the following to the fantastic answers you’ve had so far. 6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O This balanced chemical equation shows how carbohydrates, oxygen and water are synthesised from carbon dioxide and water (plus light energy). Photosynthesis occurs in plants, algae and some bacteria.
