If the man did not eat during the bike ride, why do you think that his blood glucose
level never went below 4.5 mml/L

Answers

Answer:

Due to less conversion of glucose into energy.

Explanation:

If the man did not eat during the bike ride, his blood glucose  level never went below because there is very little amount energy is used. If a person perform activities such as running and exercise etc, it requires more energy and for that more glucose is converted into energy and glucose level went down while on the bike ride very little amount of energy is needed and for that very little amount of glucose is converted into energy and the glucose level did not went below 4.5 mml/L.

Is human survival independent of other species?

Answers

Explanation:

As far as I can think of, we're dependent on other species. If we can't be carnivores, then literally, the only other option I can think of is being a herbivore, and that still an organism. We need sufficient life essence to keep living. We CANNOT live without harming another organism.

In short of my babbling, human survival is not independent of other species.

Which best explains how nutrients, salt, sediment and pollutants get into estuaries and oceans?

Answers

Answer:

There's not a "best" explanation unless it is a multiple choice question -

However, some prominent ways are

1) runoff from heavy rainfall

2) industrial discharge

3) storm drains

4) natural sediment transport via water flow / currents

Sediments, fertilizers, and other contaminants are transported to estuaries by water that drains from uplands. A large portion of the silt and contaminants are filtered out of the water as it passes through wetlands like swamps and salt marshes.

What are estuaries?

A coastal body of saltwater that is partially contained, has one or more rivers or river or lake into it, and has a direct connection to the open sea is called an estuary. Estuaries are an instance of an ecotone since they are a zone of transition between river ecosystems and ocean settings.

A place in which a freshwater river or stream joins the ocean is called an estuary. In estuaries, brackish water is created when a freshwater river and the salty ocean mingle. Although not as salty as the ocean, brackish water has some saltiness. Water that descends from uplands carries contaminants including fertilisers, sediments, and more to estuaries.

Therefore, sediments, fertilizers, and other contaminants are transported to estuaries by water that drains from uplands.

All chemical equations must be balanced. This means that the same number of atoms
of each of the elements must be found in both the reactants and the products of the reaction. Which scientific law does this illustrate?
Law of Reflection
Law of Conservation of Energy
Law of Conservation of Mass
Law of Superposition

Answers

Answer:

The Law of Conservation of Mass.

Explanation:

The reasoning behind this is that when the chemical equation is balanced, so is the amount of mass. We make sure that the chemical equation is balanced to ensure that the law of conservation of mass is conserved. This is why we add coefficients to the beginning of reactants and products to make sure that the mass of the reactants combined is the same amount of mass of the products combined.

They change because the number of valence electrons changes in a pattern that repeats in each period.

Imagine a science fiction movie in which a scientist creates a new species of organism. The scientist generates a whole population of the organism entirely through cloning of the males and females and then leaves them on an island. Explain why the population of clones would struggle to evolve if there was a major environmental change on the island.

Answers

The population of clones that struggle to evolve if there was a major environmental change on the island is :

-Lack of variations in the population as the clones are products of without fusion reproduction.

"Environmental change"

The population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.

Without fusion reproduction will allow the parent organism to produce offspring that are exactly identical to the parent.

Also it will help in production of large number of progenies at a single time.

Therefore, the population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.
