A grassland is experiencing a severe drought. The lack of rain is causing the grass to die and the ponds and creeks to dry up.

The population of fish will decrease.

The population of grazing animals will decrease.

<h3>What is drought?</h3>

A drought is a prolonged period without enough precipitation/water to support people, animals or crops.

With less water, fish and other creatures have fewer places to dwell, swim, and evade predators. In the near run, shrinking streams and lakes necessarily result in fewer fish. Drought conditions can cause water temperatures to rise, affecting cold-water species such as native trout.

The population of grazing animals would decrease as the grass is a food source and without their food source, there would be no source of staying meaning that they would result to finding new food sources through migration likely.

The important organ of the high level of plants

Roots and leaves
The major driving force of water uptake in a large tree is transpiration.Transpiration is the process by which plants absorb water through the roots and release it as water vapor through the pores in their leaves. Once this water evaporates, a negative water vapor pressure is created or develops in the surrounding cells of the leaf. when this happens, water is pulled into the leaf from the vascular system, the xylem, to replace the water that has been transpired from the leaf.This pulling of water, or tension, that occurs in the leaf, will extend through the rest of the xylem column of the tree right into the xylem of the roots as result of the cohesive force holding the water molecules along the sides of the xylem tubing.The xylem is a continuous water column extending from the roots to the leaves.Finally, the negative water pressure that occurs even to the roots will result in an increase of water uptake from the soil.

Why can't both strands of DNA be replicated at the same time?

saw5 [17]

Answer: DNA is a molecule made up of two strands, twisted around each other in a double helix shape. The two strands are complementary which have a 5 prime end and a 3 prime end. To understand this question you must first understand the steps that follow.

DNA Replication:

Step one: 

DNA Helicase (unzips) separates the strands.

Step two:

DNA Primase starts the process and makes a small piece of RNA called a primer. This marks the starting point for the DNA.

Step three:

DNA Polymerase binds to the primer and will make the new strand of DNA. DNA Polymerase can only add DNA bases in one direction, from the 5 prime end to the 3 prime end.

The leading strand is made continuously.
The lagging strand does not run continuously because it runs in the opposite direction. Each fragment is started with an RNA primer. DNA Polymerase then adds a short row of DNA bases from the 5 prime to 3 prime direction. This results in okazaki fragments because it can only replicate in small chunks. The process is repeated.

Step four:

Once the new DNA is complete the enzyme exonuclease removes all the RNA primers from both strands of DNA.

Step five:

Another DNA Polymerase fills in the gaps that are left behind with DNA.

Step six:

DNA Ligase seals up the fragments in DNA, in both strands to make a continuous double strand.

Final answer:

DNA Replication cannot replicate at the same time due to the leading and lagging strand.

Good luck!
