Answer:
Root hairs form an important surface as they are needed to absorb most of the water and nutrients needed for the plant. They are also directly involved in the formation of root nodules in legume plants. ... Having a large surface area, the active uptake of water and minerals through root hairs is highly efficient.
Answer:
Explanation:
Root hairs appear when the epidermis differentiates. The epidermis has specialized cells that are root hair cells. Much attention has been given to root hairs because of their presumed importance as absorbing surfaces.

Which statement is scientifically based? Mutations rarely occur. All mutations are harmful. Some mutations can be contagious, like infections. Mutations are not passed from parent to offspring.
Answer:
Mutations rarely occur
Explanation:
Mutations are genetic changes, i.e., alterations in the DNA sequence. Generally, mutations have deleterious effects, but there are exceptions where mutations may confer an adaptive advantage in a given environment. Mutations are often deleterious, and thereby these genetic changes are rare events. In consequence, mutation rates, i.e., the frequency by which new mutations arise in an organism over time, are generally very low. Finally, mutations that arise only in germ cells can be inherited from a generation to the next generation, while somatic mutations cannot be inherited.
The statement which is scientifically based is: A. Mutations rarely occur.
Mutation can be defined as a change (alteration) in the nucleotide sequence or genetic sequence of a living organism, which result in a variant form that may be transmitted to successive generations.
Basically, mutation is typically caused by a change (alteration) of single base units in deoxyribonucleic acid (DNA) or the insertion, deletion and rearrangement of an organism's genes or chromosomes.
However, mutations rarely occur in most living organisms due to the regulation and control of cell growth through cell cycle.
In conclusion, mutations rarely occur in most living organisms based on scientific researches.

Most viruses are about _____ times smaler than the average cell.
a 1,000
b 300
c 100
d 10
Answer:
A) 1000
Most viruses are 1000 times smaller than the average cell
And viruses are smaller again — they're about a hundredth the size of our cells. So we're about 100,000 times bigger than our cells, a million times bigger than bacteria, and 10 million times bigger than your average virus!
I would put A. 1,000 if that is your only other option

1. What is the difference between primary waves (P-waves) and secondary waves (S-waves)?
A. Primary waves are elastic waves that travel faster than secondary waves that are compression waves.
B. Primary waves are compression waves that travel faster than secondary wave with elastic rope-like movement.
C. Primary waves are compression waves that travel slower than the secondary wave with elastic rope-like movement.
D. Primary waves are rolling waves and secondary waves cause horizontal shifting, both move along the Earth's surface.
Answer:
Explanation:
Primary waves travel faster, move in a push-pull pattern, travel through solids, liquids and gases, and cause less damage due to their smaller size. Secondary waves travel slower, move in an up-and-down pattern, travel only through solids, and cause more damage due to their greater size.
The statement that best describes the difference between primary waves (P-waves) and secondary waves (S-waves) is as follows:
Primary waves are compression waves that travel faster than secondary waves with elastic rope-like movement.Thus, the correct option for this question is B.
What do you mean by Primary waves?Primary wave may be defined as a type of seismic wave that travels faster than secondary waves. They are longitudinal compression waves similar to the movement of a slinky. These are the first types of waves that are effectively detected by a seismograph.
On contrary, secondary waves are those waves that travel slower than Primary waves. These waves are detected at last by a seismograph. These waves travel only through solids.
Therefore, the correct option for this question is B.

What would happen to the velocity of a river if the gradient increased?
Answer: Therefore, the rivers speed is at its maximum at the headwaters (high gradient, high energy) and at its minimum at the base level (no gradient, lowest energy). An incoming tide can reverse a river and cause it to flow against the gradient -- uphill! Erosion and speed have a direct relationship. As speed increases erosion increases as well.
Explanation:
The velocity of a river increases if the gradient increased.
What is Velocity?Velocity may be defined as the rate of change of distance of a body with respect to time.
It is known that, if the gradient increases, the velocity of a river increases or the speed of the stream flows becomes faster. This is because the gradient is directly proportional to the velocity of an object.
Therefore, the velocity of a river increases if the gradient increases.
