Why the southern hemisphere experiences summer when the northern hemisphere experiences winter.
Answers
Answer:
Northern hemisphere and southern hemisphere are two poles of the earth that are responsible for a different environment.
Explanation:
Theses both hemispheres have different climate at its poles. This happened because of pf the tilt of the earth. on the axis. When the northern pole gets tilt towards the sun it gets to summer.
The northern poles get sarcastically hotter season. So that when the northern pole is hotter the southern pole gets cooler at that time. All has happened because the earth gets tilted towards its poles or axis.

Explanation:
Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

Those that did survive were better suited to their environment. Evidence shows that new species develop from old species as a result of gradual change. Natural selection is one process by which organisms change over time.

The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.
What is radioactive isotope?A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.
Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.
Therefore, option C that is, they break down quicker than stable isotopes is correct.

Methane only has london dispersion forces since it is nonpolar. London dispersion force is the weakest intermolecular force, so the forces between its molecules will be weak. This leads to a low boiling point that is lower than room temperature, which makes it a gas at room temperature.

Calcium reacts with a polyatomic ion to form a compound with the general formula Ca(X). What would be the most likely formula for the compound formed between potassium and the polyatomic ion X?
A) K X
B) K2X
C) KX2
D) K2X3
E) K3X2
Answers
Answer:
B) K2X
Explanation:
In an uncharged compound, the total oxidation state must be zero. The oxidation state of the calcium is +2, thus we get the following formula, where x is the oxidation state of the polyatomic ion X:
\(x + 2 = 0 \\ x = 0 - 2 \\ x = - 2\)
Also, it is known that potassium has an oxidation state of +1. Since the new compound also has a total oxidation state equal to zero, we get the following equation, where k is the number of K atoms:
\(k \times 1 + ( - 2) = 0 \\ k - 2 = 0 \\ k = - ( - 2) \\ k = 2\)
That's how it is found that the compumd consists of 2 K+ ions and one X ion.
