Reproduction

Small spiders look like the adults.

The spider and other arachnids in the ecosystem

Insects are adapted very well to their environment, as is the case with the spiders, scorpions and ticks; they can survive extremely dry conditions. They feed on other animals that are also hunters (not the tick, though, which is a parasite) and therefore play an important role in maintaining a balance in the ecosystem. Spiders therefore should preferably not be killed. The same is valid for scorpions, but care should be taken in the case of those with thick tails – they are poisonous to humans.

Assignment 4:

Study the following and answer the questions that follow:

The owner of a garden sprays poison on the plants in his garden to get rid of caterpillars. The gardener is unhappy about this and decides to have a look at how the poison affects other animals in the garden. Every day he counts how many spiders and flies, amongst others, he can find in the garden. He does not want to identify Animal X in the table. He notes down the numbers of creatures.

Number of animals that can be found in the garden within one hour on the indicated dates.

2 January 9 January 16 January 23 January
Spiders 20 10 7 2
Flies 2 12 24 38
Animal X 5 4 2 0

1. Explain what happened in the garden from 2 January until 23 January by referring to the numbers.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
