breathing involves the movement of diaphragm and Rib cage



true or false​

Answers

Answer:

True

Explanation:

It's a true statement as,

When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.

Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.

Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!

Hope this explains better :)

A. structural
B.natural
C.functional
D.behavioral
Which on is it?

Answers

B, natural adaptation

Answer:B Natural

Explanation:Camouflage is a adaptation which animals use to blend in with their surroundings in order to protect themselves from the predators and hunters. This also gives them a better chance of survival and easy mode of hunting for food.

For example: white fox hides in the snow from the predators

Camouflage is a clear example of Physical or Structural adaptations.

-Body shape, color and body patterns are the adaptations that assists both predators and prey to camouflage

-As in the example mentioned, the polar bear with its white fur hides in the snow and waits for the right time to attack its prey without being seen

go keilani

Answers

A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.

The correct answer is:

Option C. have a complementary shape to the substrate.

This can be explained as:

If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.

Activation energy is the minimum amount of energy needed for the reaction.

If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.

Therefore, the active site should have a complementary shape to the substrate.

In the diagram of the human digestive system, what organ is labelled 5?

Answers

Answer:

The large intestine

Explanation:

The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.

As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!

Answers

Answer:

The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.

For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.

Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.

Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.

However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.

A Carbohydrate is an organic compound that must be obtained from a balanced diet

Carbohydrates are food nutrients which are also organic compounds which are required for the sustenance of life because they are a very vital source of energy which the body requires for it to function properly and efficiently.

Other organic compounds are Proteins, lipids and Vitamins because they all contain elements of carbon in them. But for the Human body to be active it requires energy and the most important source of energy to the body is Carbohydrate

Hence we can conclude that Carbohydrate is an organic compound that must be obtained from a balanced diet.
