The answer is; D
The porous rock is able to absorb water from precipitation. The water resides in the pores of the rock. The impermeable rock later, which does not allow water to pass through it, allows more water to hold in the porous rock and making the local water table to rise. The water in the porous rock, therefore, can be accessed through wells or a water spring can develop.
Answer:
The correct answer is d Lysosomes contain enzymes to breakdown damaged cellular material.
Explanation:
Lysosomes are called digestive organelle that contain many hydrolytic enzymes such as acid hydrolase ,peptidase, nuclease etc which aids in the digestion of various cellular components such as carbohydrates,protein,nucleic acid.
Lysosome perform the same function by the formation of auto phagolysosome which contain the those cellular molecules and organelles those are targeted for degradation.
Answer:
You just answered yourself buddy
Explanation:
The source is the allele for beak size being different, or more specifically the DNA sequences being different.
Answer:
A
Explanation:
a. contain checkpoints that determine if the cycle will continue.
b. help move chromosomes to the new daughter cells.
c. produce more chromosomes before the cell divides.
d. grow and produce enough cytoplasm to fill two cells.

<em>The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.</em>
The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.
At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.
At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.
At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.
<u>The correct option is therefore, A.</u>
