Which of the following best explains why matter must travel through cycles?
a
There is an unlimited amount of matter in the universe, so it can take on any form at
any time.
b
There is a fixed amount of matter in the universe, so it must take on different forms
at different times.
Elements flows within ecosystem in various ways. It is important for matter to travel through cycle as there is a fixed amount of matter in the universe, so needed to be recycled.
What is cycling of matter?Matter cycling is movement of matter from one form to another or from one place to another on the Earth, inside its ecosystems.
Matter is constantly cycling from place to place, and this can have both positive or negative effects. Matter also cycles naturally, or can be due to human activity.
As there are only finite number of nutrients on the Earth, so, it is necessary for them to be recycled in order to ensure the continued existence of living organisms.
Thus, option b is correct.

If viruses are not living, how do they cause disease?
Answer:
In an episode of the classic 1950s television comedy The Honeymooners, Brooklyn bus driver Ralph Kramden loudly explains to his wife, Alice, “You know that I know how easy you get the virus.” Half a century ago even regular folks like the Kramdens had some knowledge of viruses—as microscopic bringers of disease. Yet it is almost certain that they did not know exactly what a virus was. They were, and are, not alone.

Describe the structure of atoms,including the masses, electrical charges, and locations of protons, neutrons and electrons.
Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .
Most of the mass of an atom is concentrated at the center of the nucleus.
Atoms are made up of three subatomic particles called
1. Protons
2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
Atom is a basic unit of matter have proton and neutron containing nucleus at the center and surrounding electrons.
What do you mean by atom ?
Atoms are the smallest and basic units of matter.
A negatively charged electron which surround the nucleus of the atom moving around the orbitals or energy levels.
The nucleus does not change during chemical reactions, only in nuclear reactions it will change.
In nucleus equal number of protons and neutrons, atomic number is the number of protons and atomic mass is made of the sum of protons and neutrons.
Relative mass of a matter is the mass of a proton while Relative charge of a matter is the charge on a proton.

How does a marathon runner use oxygen and produce carbon dioxide during the marathon?
is ther a tutor available can you plese check
Answer:
The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. ... When that reacts with oxygen (O2) in the cells, it produces carbon dioxide (CO2) and water (H2O). C6H12O6 plus 6O2 gives 6CO2 plus 6H2O plus energy.

What advantage did sharks have over its rivals that didn't survive the
Devonian extinction?
what similarities would you expect to find in highly resilient ecosystems
Answer and explanation:
An ecosystem that is highly resilient is one that has the capacity to resist subjected damage by maintaining its normal patterns of biomass production and the cycling of nutrients. This damage can be anything from fires to deforestation.
A highly resilient ecosystem can be expected to adapt well to change, sometimes permanently, to survive indefinitely. For an ecosystem to be resilient, it has to be flexible and be able to adjust to uncertainty. Highly resilient ecosystems tend to have reproductive cycles, trophic cascades, and population connectivity - all of these characteristics give these ecosystems better chances of surviving different types of disturbances.

Answer:
B
Explanation:
The characteristic of life is described in order to make reference that the glucose is stored in the muscle to be used later is MAINTAINING an internal balance (Option C).
Homeostasis refers to the functions of the body that work to maintain internal environmental conditions relatively constant.Insulin and glucagon are fundamental hormones that help to control sugar levels in the blood and thus maintain this homeostatic state.In muscle, glucose (sugar) is stored as glycogen.Glycogen is a polysaccharide composed of many subunits (monomers) of glucose.
In conclusion, the characteristic of life is described in order to make reference that the glucose is stored in the muscle to be used later is MAINTAINING an internal balance (Option C).

Researchers propose a model to explain variation in phytoplankton cell sizes in a marine
environment. They base their model on the idea that smaller cells absorb nutrients more
efficiently. The researchers predict that the mean diameter of phytoplankton cells will
change by 50 micrometers for every 5-kilometer increase in distance from the shore
because of a gradual decrease in nutrient availability. To test their model, the researchers
determine that the phytoplankton cells found closest to shore have a mean diameter of
900 micrometers.
Based on the model, what will be the mean diameter of the phytoplankton cells that are
found 25 kilometers from shore?
Answer:
650 micrometers
