The correct answer is option B. shown that the tidal forces needed to move continents would stop Earth’s rotation.
The Wegener’s idea that tidal forces might cause continental drift suggested that the tidal force and the centrifugal forces on the earth was the cause of the movement of the plates.
But, he was unable to propose the mechanism of such movement. Also, if the centrifugal force of the earth would move the plates apart, then the earth below it should remain stationary, but the earth is in continuous rotation, so, this idea was not acceptable, as it is would stop rotation of earth.
Answer: The correct answer is: They compete with already present animals for sources of food.
Hope this helps! :)
Explanation:
The Gila monster is one of only a handful of venomous lizards in the world. Others include the similar-looking Mexican beaded lizards, as well as iguanas and monitor lizards. Its venom is a fairly mild neurotoxin. And though a Gila bite is extremely painful, none has resulted in a reported human death.
It has been accused of many things, such as spitting venom, leaping several feet in the air to attack, stinging with its tongue, and killing people with gusts of poisonous breath. ... It may even chew so that the venom goes deeper into the wound. A Gila monster bite is painful to humans, but it rarely causes death.
Powerful muscles control the jaws and give the Gila Monster a bite like a bulldog--it just won't let go. This gives the venom a chance to work, weakening or disabling the lizard's prey.
Nine amino acids are needed to travel through the thickness of the membrane.
Alpha-axial helix's distance between amino acids is 1.5. A
The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.
Therefore, the helix's length is (21 X 1.5) = 31.5.
One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A
The thickness of the membrane is determined by the formula above to be 31.5 AA.
In the beta-strand, there is 3.5 AA between each amino acid.
Therefore, (31.5/3.5) = 9 amino acids are needed.
