What about Earth allows it to maintain bodies of water?
OA. Weak gravity and high temperatures
OB. Moderate temperatures and strong gravity
C. Strong magnetic fields and lunar tides OD. Comet crashes and mountains

Answers

Answer:

Letter C is correct

Explanation:

Earth's moderate temperatures allow water to exist in all three states: solid, liquid, and gas. Its strong gravity keeps the water from escaping into space. Hence option B is correct.

The other options are not correct. Weak gravity would not be able to hold water on Earth, and high temperatures would cause the water to evaporate.

Strong magnetic fields and lunar tides do play a role in shaping Earth's oceans, but they are not the primary factors that allow Earth to maintain bodies of water.

Here are some other factors that help to maintain bodies of water on Earth:

The Earth's atmosphere, which traps heat and prevents the water from freezing.

The Earth's rotation creates the Coriolis force, which helps to distribute the water evenly around the planet.

The Earth's tilt, which causes the seasons, affects the amount of sunlight that reaches different parts of the planet and affects the temperature of the water.

Therefore, option B) Moderate temperatures and strong gravity are correct.

C. 3C0₂ + 4H₂O + energy
D. C3H3 +3CO2 + energy

Answers

Answer: it's 3CO2+4H2O+Energy

Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.

The reaction of its complete combustion by the presence of oxygen is:

C3H8 (gas) + 5O2  ==> 3 CO2 + 4H2O + energy (2220⋅kJ)

As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.

How does cladistics reconstruct phylogenies?

Answers

Cladistics reconstructs phylogenies by considering shared derived characters between taxonomic groups and the maximum parsimony criterium.

What is the cladistic analysis?

Cladistics evaluate the relationship between different taxa according to shared characters.

The cladistic analysis follows the maximum parsimony criterium.

Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes.

It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relationship and their shared traits. One group is the sister group of the following one.

Cladistics uses cladograms to represent the common ancestral relationships and the emergence of different characters among the involved groups.

So the cladogram represents the relationship between taxonomic groups according to a derived character.

The derived character is any new trait that a group transmits to its descendants.

Through evolution, the characters change, and new changes are added. When referring to a derived character, we mean that all the subsequent groups in the cladogram carry and share the trait.

According to this framework, cladistics reconstructs phylogenies by considering shared derived characters and the maximum parsimony criterium.

Answers

The effect is that Frank's 10% sucrose bag will be heavier than that of others.

Osmosis

Water molecules move from the region of lower solute concentration to the region of higher solute concentration.

Thus, water will continue to enter into a 10% sucrose bad dropped in a beaker of water until an equilibrium is established between the 2 media.
