Answer:
The correct answer would be -
A. The number of deer would increase
D. The vegetation in the forest would decrease.

If a large number of hunters or predators are removed from an ecosystem, then there will be, the change that will be found would be increase in the numbers of the prey in the ecosystem. Due to this increase in the numbers of prey the food resources would decrease.
In the given case, the number of deers will increase in absence of enough predators which will lead to overgrazing that will decrease the vegetation in the ecosystem.
Answer:
The correct answer would be "Myosin heads attach to sites on actin filaments".
The muscle cell or myofibril consists of two types of protein filaments namely; actin (thin filament) and myosin (thick filament).
The myosin heads attach to the binding sites on the actin filaments and pull it towards the M-line in order to produce contraction.
The hydrolysis of ATP provides energy for this contraction cycle.
What help gravitational pull is Actually it's same like drinking coke through straw. Transpiration generates a sucking effect. This is called as transpiration pull and it helps in overcoming the gravitational pull downwards.
I believe the correct answer is "Carbon dioxide"
The ancient Egyptians used the stars to tell when a flood was going to happen. Every summer a flood would happen but this also happened when the bright star Sirius rose before the sun.
