According to Guinness World Records the Brazilian wandering spider (Phoneutria fera)
is officially the world’s most venomous spider. It is capable of
injecting a powerful neurotoxin which is nearly 20 times more deadly that of the Black Widow spider if it gets into the blood stream.
That is as potent as the venom of many deadly snake species and the
effects are similar. The symptoms of envenomation include a loss of
muscle control leading to breathing problems which can result in
complete respiratory paralysis and eventually asphyxiation.
But there are two other major side effects to the wandering spider’s
bite; firstly there is intense pain and secondly, if you happen to be
male there is the four hour hard on. Yes, you did read that correctly –
the bite of the Brazilian wandering spider can cause an erection that
lasts for several hours, unfortunately it is also painful.
In
addition to the this deadly venom the behaviour of the wandering spider
make it particularly dangerous to humans. As its name suggests the
spiders are not confined to a web in a dark corner. In fact they like to
turn up in all manner of hiding places; boots, piles of clothes, log
piles, cars and bunches of bananas. Also known as ‘banana spiders’
wandering spiders have been known to hitch a ride across the globe in
boxes of bananas. In one case a man in the UK was bitten after buying
bananas in his local supermarket.
There is little doubt that these
are dangerous spiders. Their aggressive nature and close contact with
humans have resulted in a number of deaths over the years. In one tragic
case a single spider was responsible for the deaths of two children
in São Paulo. Fortunately an effective antivenom has been developed and
there have been relatively few fatalities since.
1. What is the function of plant roots?
- A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) vegetative reproduction and competition with other plants.
2. What is the function of root hairs?
- The function of root hairs is to collect water and mineral nutrients present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis they do not contain chloroplasts.
3. What plant tissue are root hairs made from?
- Vascular Cylinder. Much like in the plant stem, the vascular cylinder in the root contains xylem and phloem. Xylem moves water and dissolved minerals within a plant, while phloem moves food throughout a plant.
4. What plant physiological processes will be affected if the root and root hairs were
<u>The question is incomplete give me the full question and I will answer it. </u>
5. Explain how roots and root hairs affect
- The root hairs are where most water absorption happens. ... The function of root hairs is to collect water and mineral nutrients present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis they do not contain chloroplasts.

6 is the same as 5. </u></em></h3>
7. What is the purpose of transpiration in affected?
- Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, it must be accurately regulated. The ingenious system that regulates this function consists of a guard cell on each side of the tiny pores (stomata).
Answer:
Whichever hemisphere (the Northern or Southern Hemisphere) is tilted toward the sun receives more direct rays of sunlight (or rays that are closer to perpendicular or a 90° angle). The hemisphere tilted toward the sun also has more hours of daylight than the hemisphere that is tilted away from the sun
