Answer:
The correct option is 'A'
The breezes are the pollinator of pine trees.
Explanation:
Pine tree belong under genus Pinus and family Pinaceae which are important for it's timber and wood pulp.
Pine trees are mostly monoecious as the male and femlae contain cones which is present on the same tree but few are sub dioecious with single sex.
As they lack flowers,so pollination is not done by bee or butterfly.But they mainly pollinate by breeze or wind.
Female cone require 1.5 to 3 years to gain maturity after pollination.
At the onset of maturity, the diameter of female cone is 3-60cm long
Answer:
No
Explanation:
That would not be likely. It is a very complicated cycle
Seismic waves travel in all the directions and used to determine the magnitude of an earthquake. There are 3 types of seismic waves that move in different directions.
1. P wave: It is the fastest of all three waves that travel through the interior of the earth and are compressive waves.
2. S wave: Secondary waves generally follow the P waves and travel through the interior of the earth but are shearing waves.
3. Surface wave: This is the slowest of all three waves that moves close to the surface of the ground.
These waves affect the movement of other materials when they are passing through the interior or surface of the earth.
P waves can move through the solid rocks and even liquids. S waves do not travel through the liquids such as water and molten magma. Surface waves causes shaking of the ground and do not go deep inside the earth.
Answer:
It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.
Explanation:
Mut L protein is involved in mismatch DNA repair. MutL protein is complexed with MutS protein and the MutL-MutS complex recognizes all the mismatched base pairs present in the newly formed DNA strand. The complex can not recognize the "C-C" pairs. MutH protein joins the complex.
The MutH protein also has a site-specific endonuclease activity and cleaves the unmethylated DNA strand towards the 5' end of the guanine base in the GATC sequence to mark the strand for DNA repair. In this way, MutL protein, along with MutS and MutH proteins mark the mismatched DNA bases for repair so that they are not translated into a faulty protein.
