Answer:

The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?

Explanation:

The layers of the atmosphere are determined based on air temperature, the energy in the air molecules comes from the sun, which increases the temperature of the atmosphere.

There are different layers of the atmosphere. There are seven layers of atmosphere. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

The sun is the only source of energy for the atmosphere. It provides heat or thermal energy and which is acquired by different molecules and these molecules convert this energy into other forms of energy.

Thus, the energy contained in the molecules of the air is derived from the sun, which raises the temperature of the atmosphere, which in turn determines the layers of the atmosphere.

Answer: It provides protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. Clotting mechanisms are also present that protect the body from blood loss after injuries.

Answer:

The human circulatory system has a complex network of blood vessels that reach all parts of the body. This extensive network supplies the cells, tissues, and organs with oxygen and nutrients, and removes carbon dioxide and waste compounds.

Explanation:

The protein function listed here which suggests that most enzymes are proteins is that they speed up chemical reactions. That is option D.

Proteins are one of the classes of food that contains nitrogen in addition to carbon, hydrogen and oxygen.

Enzymes are those substances that helps in the breaking down of food substances into simple, soluble and diffusible substances before they can be absorbed into the body. It speeds up chemical reactions in the body by lowering the activation energy.

Enzymes are often referred to as proteins because proteins speeds up biological processes (chemical reactions) which is the same function performed by an enzyme in a living organism.

Answer:

C) the sun's rays that fall on the moon's surface.

Explanation:

The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.

Answer:

It provides more surface area for the absorption of oxygen.

Explanation:

The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.

Answer:

The correct answer is - variables that they didn't control and not enough replicates

Explanation:

In this particular case, Pablo and Johanna using too many variables in their experiment or research, All the variables used, are not controlled and with time these variables can not be replicated again on experiment groups.

They did not select a particular age or weight of dogs, the diets are different and they feed dry kibble to only one dog. There are so many variables and for a better result experiment, all variables should be controlled only the independent variable is permitted to manipulate.

Answer:

Claim: Various factors can tree frogs to change color, such as outdoor temperature, brightness of light and moistness of the air.

Evidence:  According to the National Wildlife Foundation "Tree frogs can be a variety of colors, but most of the species found in the United States are green, gray, or brown. Some of them, like the squirrel tree frog (Hyla squirella), are chameleon-like in their ability to change color."

Reasoning: Other factors can cause the variation of colors in tree frogs, these can be used as defense mechanisms to protect or camouflage themselves among their surroundings

Explanation:

To answer these types of questions you just go through it as a process step by step.

Answer:

- Homeostasis is the ability of living systems to maintain a steady and uniform internal environment to allow the normal functioning of the systems.

- It is the tendency to achieve equilibrium against various natural and environmental factors.

- Homeostasis results in a dynamic equilibrium, where continuous changes keep on taking place, and yet steady conditions are maintained.

- Homeostasis is mainly involved in managing various internal variables of the living system like body temperature, pH of various fluids, the concentration of different ions, and the body sugar level.

- A number of regulatory mechanisms are employed to resist changes in the body against environmental and bodily factors.

- Homeostasis can be maintained by separate organs or by the entire body at once.

Maintaining homeostasis/Homeostasis Mechanisms

Homeostasis is maintained by a complex system that consists of individual units working in a particular sequence to balance a given variable. All homeostasis mechanisms consist of four separate units, which are:

1. Stimulus

The stimulus is something that results in changes within the system involving the variable.

The stimulus represents that the variable has moved away from its normal range, initiating the process of homeostasis.

One example of this is the increased temperature of the body above 37°C due to various causes. The increased temperature indicates that the temperature of the body has gone higher than its higher range.

2. Sensor/ Receptor

The sensor or receptor is the sensing unit of homeostasis, where it monitors and responds to the changes in the body.

The changes in the system are realized by the sensor, which then sends the information to the control unit.

The nerve cells and receptors like thermoreceptors and mechanoreceptors are examples of sensor/ receptors.

3. Control unit

Once the information is sent to the control unit, it tallies the changed value to its normal value.

If the value is different from the normal value, the control center activates the effectors against the stimulus.

The thermoregulatory unit in the hypothalamus of the brain that controls the temperature of the body is an example of the control unit.

4. Effector

Effectors can be muscles, organs, glands, or other similar structures that are activated as a result of the signal from the control unit.

An effector is a target which is acted upon by the control unit to bring the value of variable back to normal.

The effector essentially counteracts the stimulus to nullify its effect.

In the case of thermoregulation, the sweat glands are effectors that are acted upon by the thermoregulatory unit to produce sweat so as to bring the value of body temperature back to its normal value.

Answer: Point sources of pollution

Explanation:

The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.” Factories and sewage treatment plants are two common types of point sources.

Hi There ! Well let's comprehend the topic a bit better and let me walk you through...

Heat!We normally use heat to make food A cup of coffee in the morning or When we are doing our backyard hangouts we use heat to make Yummy steak!Heat isnt always just used to make food!We use heat to Warm up our houses ! Like a chimney we make heat to warm up our houses! Or some people use furnaces it also produces heat and warms up your room or house! Well now that we know what we use it for ....What is heat?

Of course Heat!

Heat is The energy that transfers to many different entities With a slight or major temperature difference!Please take in mind that heat only transfers to objects that are cooler than heat itself!Which means that it is energy that is transferred (or that flows ) from one object or system to another!

More info!

What are the 3 types of heat?Conduction, Convection, and Radiation.Heat can be measured in  Btu, calories or joules what we use to measure heat is hermometers and pyrometers!
