How does an increase in the annual melt season in Antarctica have a global effect?
a.
It causes an increase in heat related illness and death.
b.
It causes the global concentration of carbon dioxide to decrease.
c.
The water in the melting glaciers can cause sea levels to rise.
d.
None of the above is true.
Please select the best answer from the choices provided
A
B
C
D
Answer:
The correct answer is option "C"
The water in the melting glaciers can cause sea levels to rise.
The increase in annual melt season indicates a prolonged melting (hot) season which is primarily due to the impact of global warming. Global warming is increasing the highest temperature mark in the hot seasons on the planet which is adversely affecting the polar regions of earth. The ice in these Polar Regions has started melting. This ice when converted into liquid form flows through regions to reach sea and oceans and thus causes the rising of sea level
The annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.
What is the annual melt season?The annual melt season refers to a period of time when the ice in cold and polar regions of the world begin to melt to form warm.
The melting of ice in these regions such as Antarctica results in a rise in the global sea levels.
Therefore, the annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.

After a particularly fierce blow, he crawled to his feet, too dazed to rush. . . . All the pain he had endured was as nothing compared with the exquisite agony of this. With a roar that was almost lionlike in its ferocity, he again hurled himself at the man. But the man, shifting the club from right to left, coolly caught him by the under jaw, at the same time wrenching downward and backward. Buck described a complete circle in the air, and half of another, then crashed to the ground on his head and chest.

Egg + Heat
Proof of a Chemical Reaction
Answer:
Water+Heat
proof of physical reaction
Explanation:
Chemical reactions are reactions that can't be undone ex cooking and egg.
Physical reactions are reactions that can be undone ex boiling water.
Answer:
Egg + Heat = Chemical Change
Explanation:
This is a chemical change because it cannot be undone. Once it changed its form you could not revert it back to its original self.
I hope this helps you! :)))))

This reaction shows that when ammonia react with oxygen it form water and nitrogen gas.
There are two reactants on left hand side oxygen and ammonia. Ammonia is formed when nitrogen and hydrogen react. While on right hand side there are two products nitrogen and water. Water is formed by the reaction of hydrogen and oxygen.
The given reaction also shows that it follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
how are electrons arranged in elements with atomic numbers 1 through 10?
Answer:
See explanation
Explanation:
For elements with atomic numbers 1-10, the arrangement of electrons is as follows; 1s 2s 2p.
These elements are found in the second period that commences at lithium and ends in neon.
The ten electrons that may be found in the atoms of these elements are arranged in orbitals as shown above.
What is an indicator? What does it tell you about solutions?
Answer:
Pure water is neutral, and so is petrol. An indicator is a substance that changes colour when it is added to acidic or alkaline solutions. You can prepare homemade indicators from red cabbage or beetroot juice - these will help you see if a solution is acidic or alkaline.

Why don't molecular compounds conduct electricity when dissolved in water?
Answer:
Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don't dissociate into ions and so don't conduct electricity in solution.

disease it cames will spread
Why is this considered a theory instead of a hypothesis
or a law?
Answer/Explanation:
A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.
A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.
A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.

Why are electron filling orders not the same between the first and the last two elements of group 6B?
Answer:
This primarily has to do with the balance of energy between the orbitals. The aufbau principle states that the order of energy regarding electrons in the orbitals from lowest to highest is so the electron in the atom will minimalize it's energy. Periods on the periodic table are based on the energy level while the groups have the same amount of valence electrons. The outer orbitals are refered to as shells. The elements are particularly arranged depending on their atomic and molecular orbitals. Valence electrons most determine the chemical properties of an element. The atomic number is based on the number of protons.HELP!!!! PLEASE, it would be much appreciated.
