Air can escape from the bottle (1/2m)

The heart needs to pump blood faster so that blood can transport water, oxygen and digested food to all cells for respiration to occur to release energy.

# data[].attributes.body
When the switch was closed, it formed a closed circuit and electric current could flow through the circuit so metal bar X became an electromagnet. Hence, since iron is a magnetic material, the iron ball got attracted to X. Thus, the iron ball moved towards metal bar X.

X: Nitrogen
Y: Oxygen

When Tino increased his running speed, his body needed more energy so his heartbeat increased to send more blood carrying water, oxygen and digested food faster to the rest of the body.

38C: (A)  E: the mass of the towel A is decreasing faster than towel B.          R: This is because towel A has more exposed  surface area to for the water to evaporate faster whilst towel B is folded therefore it has less exposed surface area to dry.

Cup A. Since Cup A felt cooler tahn cup B, cup A lost heat heat faster than cup B and hence is a better conducyor of heat that cup B and will melt more quickly

# data[].attributes.body
This is the answer formed by our group

# data[].attributes.body
c) It took a longer time to dry as in the shade, there is not as much sunlight and wind compared to open air. The sunlight helps warm the towel and the breeze help dry the towel so without it, the towel would take a longer time to dry.

# data[].attributes.body
Do look at your friend's comment - is not the moisture from the freezer  that is condensing,  it is the warm water vapour in the surrounding that comes in contact with the cooler air in the freezer.

# data[].attributes.body
You don't know that no wind was present as the question only stated that it was placed in the shade. In the shade may mean outside under a tree or under something that is hanging outside
so wind may have been present. In your answer maybe u can remove the part about the wind.

# data[].attributes.body
In Question (a) before u write 'condensed' i think it would be better if you wrote 'lost heat and condensed' but other than that your answer seems very good and detailed.

# data[].attributes.body
i dont think it is the moisture inside the freezer. its more like warmer water vapour in the surrounding air came into contact with the cooler air around the freezer, lost heat & condensed into tiny water droplets (mist). and for the 2nd question I think you can talk about the mist (tiny water droplets) gaining heat and evaporating.
Gayatri

# data[].attributes.body
Very good complete answer

# data[].attributes.body
Good answer

# data[].attributes.body
for the last question i think it reduces overcrowding and competition for sunlight, water, nutrients and space. for the second question i think it is to obtain more reliable results by taking the average of the readings for each time
Gayatri

# data[].attributes.body
im not clear with this question. i dont think there are ovules in the ovaries of q and p so fertilisation cannot take place and they cannot develop into fruits.
Gayatri

# data[].attributes.body
34c i think you can talk about him being able to respire/carry out life processes faster and releasing energy faster this way. maybe you can also talk about carbon dioxide being removed from his body at a faster rate.
gayatri

# data[].attributes.body
yes you can remove the part about the wind. and for 38b a better answer might be that from 120min to 180min its mass remained constant which shows that water did not evaporate and it is completely dry since if it was still wet the mass will decrease as the water evaporates so it is completely dry.
Gayatri

# data[].attributes.body
I think that the stigma is not necessary as pollination has already taken place.I think you have to mention about the ovaries and ovules as they develop into fruits and seeds

a) Air has a fixed volume.
b) Put the same amount of heat.
c)There was more layer of 'd' air, causing the wax to melt slower.
d)Fur coat Y. Y had more layer of air allowing the hold air from the surrounding air to be trapped in the layer of air than fur coat X, as X has a smaller layer of air than Y.

(b) Plants cannot reproduce by themselves and need pollinators to help them with process A.
