The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.
It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.
This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.
Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.
Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.
It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
Thus, having an optimum temperature is essential in functioning of enzymes.

How do you train your dog to stay? Include details and be specific
Answer:
Simply put your hand out and block them and put them back in the corner in a sit position. make sure that you let your dog know that not moving is what gets them. The reward gradually increase the distance and time as we did in the corner until they can stay for 10 seconds at 10 feet away.
Also, with a leash, when teaching your dog to stay, say "stay" and pull the leash back to when the dog is sitting. This gives the dog an understanding of what to do and how to do it. Repeat this a few times. Then the dog will learn to sit and stay before the leash stops. Then they will have learned the "Stay" command.
Hope this Helps!
Answer:
Positive reinforcement is one of the best ways to train a dog. This may be treats, such as a biscuit, or affection, like a belly rub. There's also giving them a new toy, or taking them on a walk even. Most trainers have these tools called clickers. They get a dog's attention and keep it, refocusing them if they wander off mentally.
Not all trainers train their dogs to stay the same way. More popular ones may give the command "Sit!", which sometimes isn't very effective. I personally trained my dogs with a type of sign language. One finger up for "sit", and two for "stay". Full hand is "down" or "wait". As I said, many different ways of training.
If a dog does not respond to positive reinforcement, there is negative reinforcement, but it is seriously frowned upon. This could be a water bottle or receiving no treats. Some people take this too far, however.
The best way to train a dog to stay is to be patient with them, use positive reinforcement, and to understand. They're a dog, they're bound to be distracted, just like a child. To refocus them, snap your fingers or whistle, and if need be, call their name. Don't expect them to learn it all in one day: all dogs have different personalities and learning capabilities. One dog may pick it up quick, while it may take another month to learn, just like humans.
You also have to take into consideration age and history of the dog. These are two very important factors in training, as if a dog is used to being spoiled rotten, positive reinforcement most likely won't help. If the dog is a young puppy, they're going to want to learn and explore instead.

Answer:
Molecule 3
Explanation:
DNA contains Deoxyribose, Phosphate, and 4 bases: Adenine(A), Thymine(T), Guanine(G), and Cytosine(C)
Molecule three contains Deoxyribose, Phosphate, and Guanine, while the others do not.
RNA contains ribose, which is why Molecule 2 is out of the question.
DNA does not contain glucose, henceforth marking Molecule 1 incorrect.
Molecule 4 may seem correct, but recall that DNA contains Deoxyribose, Phosphate, and a base, in this case Guanine(G). This answer contains no Deoxyribose.

Answer:
Inflammation
Explanation:
Innate Response:
"The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system. It acts very quickly: For instance, it makes sure that bacteria that have entered the skin through a small wound are detected and destroyed on the spot within a few hours. The innate immune system has only limited power to stop germs from spreading, though. The innate immune system consists of: Protection offered by the skin and mucous membranes AND Protection offered by the immune system cells (defense cells) and proteins."
Acquired Response:
"The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection. But to do that it first needs to identify the germ. This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster. The adaptive immune system is made up of: T lymphocytes in the tissue between the body's cells AND B lymphocytes, also found in the tissue between the body's cells AND Antibodies in the blood and other bodily fluids."
I'm sure it's Inflammation, so here is the definition for that:
"Inflammation refers to your body's process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system."

2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.

1) A vehicle is traveling at 150 km/h after 3 hours it is traveling 240 km/h.
Was the vehicle accelerating or decelerating and at what rate?
(And this is for science not biology)
Answer:
Accelerating (30km/hr²).
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]t is time measured in seconds.Given the following data;
Initial velocity, u = 150km/h
Final velocity, v = 240km/h
Time, t = 3 hours
Substituting into the equation, we have;
[tex]a = \frac{240 - 150}{3}[/tex]
[tex]a = \frac{90}{3}[/tex]
Acceleration, a = 30km/hr²
Therefore, the vehicle is accelerating at the rate of 30km/hr² because its final velocity is greater than its initial velocity.
For deceleration, the final velocity of an object such as a vehicle would be lesser than the initial velocity.
Over various spans of time, human populations have increased, decreased, or remained the same, and at both global and local levels. Which statement best explains this observation?
Answer:
C. Like other populations, the human population is affected by a variety of factors in the environment
Note: The options are found in the attachment below
Explanation:
Factors that affect population in the natural world include; availability of food, water, shelter, space, competition for resources, predation, as well as disease.
These factors also affect human population resulting in an increase, decrease or stability in population.
Regarding decrease in population, factors like competition for scarce resources has resulted in wars which greatly reduced human population. Also disease outbreaks, droughts, famines, etc have resulted in decrease in population.
Availability of food, water, shelter and space on the other hand makes for an increase in population by increasing the birth rate, reducing competition and bringing stability.
In some other instances, overtime, there is a balance between birth and death rate, so human population will remain relatively unchanged at these times.
