Answer:
Stomata
any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases in and out of the intercellular spaces.

Answer:
Genetic drift reduces the size of gene pool of the population.
Explanation:
Genetic drift is any chance event that results in changes in the allele frequency of a population. The event either fixes an allele on the particular locus or makes the population to lose that allele.
Hence, genetic drift changes the genetic frequency by removal of a particular allele or by fixing it in the gene pool. Both conditions lead to reduced genetic variations in the population. And since genetic drift reduces the size of the population, the gene pool of the population would also shrink due to loss of alleles from it.
B.A forest cut down by a logging company
C.A forest Flooded for a week following heavy spring rains
D.A forest decimated by an avalanche
The correct answer is (b) A forest cut down by a logging company.
The most common method of logging is clear cutting because it is economically profitable. When a logging company use clear-cutting to cut down the forest, they cut each and every tree by tools in such a way that there are very least chances that a whole forest will recover. The remaining parts of tree cannot grow again and thus cannot restore the forest.
Answer:
DNA is responsible for traits.
A section of DNA that codes for a specific trait is called a gene.
Half of your DNA comes from each parent.
Your traits are a combination of your parents’ traits.
DNA is the blueprint for proteins, which play many roles in the body.

canoe. Use Newton’s third law to explain why this happened. Hint: First
identify the action-reaction pair in this example.
Answer:
Resistive force from canoe in backward direction
Explanation:
As per Newton's third law of motion for every action, there is an equal reaction and that too in the direction opposite the direction of main action.
Here, the action reaction pair is the contact point of Emilio or the Canoe.
When Emilio tried to jump on the dock, he exerted an action force i.e the KE+PE in the forward direction but while jumping he pushed behind the canoe which in turn exerted resistive frictional force in the backward direction on Emilio which restricted him from jumping exactly on the dock.
