can anyone please help with the effect of environment on phenotype with the hydrangea and coloured light pracs please

i) The xylem and phloem are part of the transport system within the plant. Xylem transports water and ions up from the roots and only goes in 1 direction - up from the roots to usually the leaves. Phloem transport organic materials and products of photosynthesis up and down the plant.

ii) Kidneys - Know about the 3 sections and what they're responsible for: -Cortex (filtration), -Medulla (Reabsorption), -Pelvis (Collection)
- The nephron parts e.g. Loop of Henle, distal tubules, glomerulus, Bowman's capsule.
- What happens within them e.g. Tubular reabsorption, ultra filtration.
- The structure through dissection

And yes, it is safe that you know ALL experiments.

can someone tell me what ALL the experiments are? just list em

Thank you so much!!

I'm also a bit stuck on rhesus factor inheritance. I've read a few different explanations, but I'm not sure which is right!

Module 1-
1. Effect of Temperature on enzyme activity-
2. Effect of pH on enzyme activity -
3. Effect of substrate concentration on enzyme activity-
4. Effect of dissolved CO2 on pH of water-
5. Investigating blood cells-
6. Conducting tissues- Xylem and phloem-
7. Dissection of Kidney-
8. Water Conservation in plants-
Module 2-
1. Model of Natural Selection-
2. Model of meiosis-
3. Effect of environment on phenotype-
4. Model for polypeptide synthesis-
Module 3-
1. Identify microbes in water-
2. Model of Pasteur’s experiment to identify the role of microbes in decay-
3. Plant Diseases-
Module 4-

In addition to the A and B antigens on the surface of the red blood cells, there is also another substance called Rhesus factor
The Rhesus factor is either present or absent on the cell – Every person either has a Rhesus protein (Rh positive/ Rh+) or does not (Rh negative/ Rh-)
The Rh+ allele is dominant over the Rh- allele

hope that helped

there's an actual prac for the kidney disection? what are you meant to write?

all you did was cut it in half and poke it?

wtf is this? is this part of an optional?

 

[madharris]

yeah it's the genetics option don't worry

 

[cornchips1]

Queessstioon.. are you allowed to like in the short answer bit like draw a table or like draw a punnet square as part of your answer?

 

[Newbit]

How should I spend my last few hours studying for Bio? Just binge on past papers?

yes, depending what the question is.

yeah past papers, read your notes for anything you don't understand

 

[ZombieApocalypse]

thank god!


Also, transgenic species are produced through recombinant dna, right?

can anyone help me with the hydrangeas and effect of light on plant growth prac. it goes under the effect of environment on phenotype

ur supposed to observe and identify the different parts of the kidney, both external and internal, and also relate the function of the kidney with its structure.
