Opinion: is our current water use sustainable? Why or why not?

Answers

Answer 1

Answer:

This actually depends, since most of our water is filtered (depending on where you live) then yes it is sustainable! But if our water wasn't filtered then no, it would not be sustainable. This is because of all the things that go into our water before it's filtered. We've got plastic, trash, dead fish and all that, in some cases sewer system drainage and a lot more that goes into the filtered water that we drink.

A person who is exercising vigorously breathes more deeply and rapidly than someone who is resting. Give TWO reasons why this is necessary.

Answers

During physical exercise, more oxygen is used up and more carbon dioxide is produced leading to faster and deeper breathing.

Physical exercise is a state in which the muscles are flexed much vigorously leading to a faster heartbeat owing to a quicker rate of pumping of the blood by the heart.

There are two main reasons why a person engaging in physical exercise tends to breathe faster and more deeply;

The muscles tend to work harder during physical exercise hence more carbon dioxide is produced.The body uses up oxygen more quickly leading to a greater demand for oxygen and thus a faster and heavier breathing rate results.

Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.

Long paragraph:

The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.

how does the plasma membrane contribute to the structure and function of the cell?

Answers

Answer:

The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it moves hazardous materials out of the cell and carries nutrients into the cell.

What is a cell membrane?

All cells' interiors are protected from the outside world by a biological membrane called the cell membrane. A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move substances out of the cell that are toxic as well as nutrients into the cell.

Glycerophospholipids, molecules made of glycerol, a phosphate group, and two fatty acid chains, are what make up cellular membranes, including plasma membranes and internal membranes.

Tại sao con người chúng ta lại sốt nhiều lần như vậy?

Answers

Answer:

Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.

Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.

Kim's Dalmatian, Tigger, always eats the same brand of food. Although he does everything else at lighting speed, he is a very slow eater. After watching a TV commercial touting the irresistible taste of Puppy Yums Dog Vittles, Kim decides to conduct an experiment comparing Tigger's regular food (K-9 Crunchy Bits), Puppy Yums Dog Vittles, and a store brand that cost 1/3 as much as the advertised food. Kim gave Tigger the same quantity of each different food, on three successive evenings, and used a stopwatch to determine Tigger's dinner-time munching speed.

Hypothesis:
Predicted Results:
Independent Variable:
Dependent Variable:
Control Variable:

Answers

The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.

An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.

In this experiment;

The independent variable is the type of dog foodThe dependent variable is the eating time of the dogThe predicted result is that the dog will eat the advertised Puppy Yums Dog Vittles faster than the other dog foodsThe control variable is the quantity of dog food given to the dog each evening.The hypothesis of the experiment is that the dog will eat the advertised tasty food faster than it eats its regular food.
