Have you ever wondered how many times your heart beats in a day, a month, a year—or will beat in total throughout your life? Over an average lifetime, the human heart beats more than 2.5 billion times. For a person to keep their heart healthy, they should eat right, not smoke and get regular exercise. In this science activity, you'll measure your heart rate during different types of physical activities to find out which gives your heart the best workout to help keep it fit.
Background
A 150-pound adult has about 5.5 liters of blood on average, which the heart circulates about three times every minute. A person's heart is continuously beating to keep the blood circulating. Heart health experts say that the best ways to keep our hearts healthy is through a balanced diet, avoiding smoking and regular exercise.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.

Answers

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.

Answer:

You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.

The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

How does the size of a bacterial cell compare with an animal cell?

Answers

Answer:

hope it helped

Explanation:

Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.

Blood vessels are connected to nerve fibers which are regulated by the
nervous system. When innervated they respond by doing what?

Answers

Answer:

When blood vessels are innervated they respond by contracting and relaxing their muscle wall, as a result of the activity of the autonomic nervous system.

Explanation:

The nerves that are responsible for the innervation of the blood vessels are called nervi vasorum, and are composed of nerve fibers of the sympathetic and parasympathetic nervous systems.

The innervation of the blood vessels specifically acts on the muscular wall of the vessel, so it contracts or relaxes depending on the activity of the nervous system:

Sympathetic nervous system stimulates vascular contraction.Parasympathetic nervous system makes the vascular smooth muscle relax.

The action of the autonomic nervous system has an effect on blood pressure, being a determinant of normal or pathological behavior of the arteries.

The ecosystem which is most likely has the greatest biological diversity and therefore the highest sustainability is a rainforest that has many types of plants and animals. Therefore, the correct option is D.

What is ecosystem?

An ecosystem refers to the biological community where the biotic as well as the abiotic components interact with each other and influence each other.

It encompasses all the living organisms in a specific area as well as physical and chemical factors that shape their environment such as air water soil climate and environment. They play an important role in functioning the earth's biosphere, as they provide a range of essential services.

The study of ecosystem and interaction between is components is referred to as ecology. Hence, the correct option is D.

Water is an adhesive substance. This means that water particles
A. are attracted to other types of particles.
B. are repelled by other water particles.
C. are attracted to other water particles.
D. are repelled by other types of particles.

Answers

Answer:

A

Explanation:

are attracted to other types of particles.

Adhesion is the term for the attraction of substances between distinct phases. It uses the attraction of water to other polar compounds, as an illustration, hence option a is correct.

What is the characteristic of water?

Cohesion is the tendency of particles to cling together, it uses the attraction of water molecules to one another.

Water has a characteristic called cohesion in which water molecules form bonds with one another. As a result, surface tension develops and raindrops start to form.

Water molecules can interact with other molecules through adhesion, this enables water to adhere to surfaces like windows and other things.

Therefore, water is a strong adhesive that adheres effectively to many different materials, hence option a is correct.

Answers

Answer:

This is too difficult to read and understand... if you had a diagram I could be able to help more, but I can't figure out exactly what your asking... all I know is part A is CO2 being released into the atmosphere...

Hope you have a great day and if you have a diagram let me know.. I'd love to help :D

Answer:

Part I

At location G, the process of combustion is taking place where hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide and water as the products.

CxHy = CO₂ + H₂O

Part II

At point G there is no transformation of energy since during the process of combustion energy will still be stored in form of chemical energy in the bonds of carbon Iv oxide and the water produced during the reaction.

Part III

The process shows recycling of carbon in the carbon cycle. This is because carbon from living organisms is cycled to non living organisms. When plants and animals die and are buried deep in the ground, they are then slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds. Then the fossils are used in the industries and undergoes combustion releasing carbon iv oxide which is then released to the atmosphere and used by the plants and animals. The process starts once again.

Which pair of structures would provide a positive identification of an animal cell under a microscope?

flagellum, lysosome


nucleus, mitochondrion

ribosome, cell wall

chromatin, chloroplast

Answers

flagellum, lysosome: Both of these are found in animal cells, but the real difference is flagellum is ONLY found in animal cells

nucleus, mitochondrion: Both of these are found in Animal cells X

ribosome, cell wall: Cell wall is only in plants X

chromatin, chloroplast: Chloroplast is only found in plant cells X

Explanation:

Firstly cell wall and chloroplasts can only be found in plant cells and will not appear in an animal cell.

Flagellum usually appears in many bacteria (microorganism) and only a few animal cells. Most animal cells do not have flagellum.

However animal cells do have a nucleus which contains important genetic material such as DNA and mitochondrion which creates energy for the cell to use for metabolism inside the cell. (Even though most eukaryote cells have these 2 organelles)

Between the 1st and 2nd options, none of them is exactly correct. But nucleus and mitochondria are more widely found in various types of cells (plants, etc.)

I would choose the 1st option as the best answer here because it is more detailed.
