The answer to your question is hemoglobin
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.
Answer:
Spring Tides.
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.
This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
The various types of ocean tides based on the position of the Earth, Moon and the Sun are;
I. Neap tides.
II. Spring tides.
III. Low tide.
IV. High tide.
V. Brown tide.
VI. Rip tide.
VII. Red tide.
Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.Mar 30, 2014

Explanation: The relative melting points of the layers each increase the deeper you go into Earth's mass.
