Lessen impacts of flooding by absorbing water and reducing the speed at which flood waters flow. Upstream wetlands can serve to store flood waters temporarily and <span>release them slowly downstream.</span>
The correct answers are:
Tissue level- similar cells work together to accomplish a goal.
Examples of tissue are muscles, skin, bone, and brain (nervous tissue).
A sponge is an example of an organism that is only organized to the cellular level.
Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)
