How did the first small organic molecules form in earth’s earliest atmosphere? There are two main theories discussed. Make sure you know both. Refer to Miller and Urey experiment and meteorite theory
zapped gas/liquid into amino acids
many amino acids thought to have come from meteorites
a mixture of gases and water that Miller thought were present on early Earth was heated and zapped with electricity to mimic lightning. This created five identifiable amino acids
newscientistcom
We know amino acids exist in some kinds of meteorites and interplanetary dust
Many left-handed amino acids were found inside the Murchison meteorite. Most were kinds not found on Earth.
92 different amino acids have been identified in the Murchison meteorite. Of these, only 19 are also found on Earth. The remaining amino acids have no apparent terrestrial source. This discovery led scientists to consider the possibility that Earth's life forms originated elsewhere in the universe. And the same cosmic process that may have helped life arise on Earth could also be seeding life elsewhere in the universe

When two amino acid monomers are positioned so that the carboxyl group of one is adjacent to the amino group of the other, they can be joined through a dehydration reaction. This reaction forms a(n) peptide bond.What are amino acids ?Amino acids are monomers which make up the proteins, while proteins are made up of more than linear chain of amino acids which are known as polypeptide.

Tree squirrels can have different fur colors.
Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch.
[IMAGE ONE]
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.
The diagram below shows how the population changed after many generations.
[IMAGE TWO]
How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.
Answer:
The gray squirrels were easy to see and catch so they died quickly and the population dwindled. The brown squirrels were probably almost the same color as the tree so they were harder to see and catch. The remaining gray squirrels ended up having no other options than to mate with brown squirrels, which probably made appear black squirrels and since the black squirrels population raised, means they are harder to see and be caught by foxes.
How the trees became more black too? I have no idea, sorry.
Explanation:
squirrels: brown, gray

Pls helpthe sun hits the ocean at the equator more directly than at the poles. how does this support the flow of currents in the ocean?
The Sun creates a lot of thermal energy in the atmosphere and the oceans. Currents created as warm equatorial waters move to the north carrying heat. Due to this, the cold polar waters go south, and there get heated.
What is thermal energy?Thermal energy refers to the energy within a system and is responsible for its temperature.
The Sun heats up the air at the equator. This air will move toward the poles and cools down there with time.
In this process, the wind that occurs due to air currents will induce currents at the ocean surface.
The currents at this surface are propagated down deeper due to the differences in the forces on different parts of the water.
Thus, It is the main reason that the sun hits the ocean at the equator more directly than at the poles.

The digestive system includes the esophagus, stomach, large intestine, and small intestine.
All of these parts are made up of cells.
Which of the following is true about the cells in the digestive system?
Choose 1 answer:
(A) cells in the stomach and large intestine have the same structure, but different functions.
(B) each cell in the stomach and large intestine is a unique type of cell.
(C) cells in the stomach and large intestine have different, specialized structures and functions.
Answer:
C is the correct answer of this question
The statement which is true about the cells in the digestive system is that the cells in the stomach and large intestine have different, specialized structures and functions. Thus, the correct option for this question is C.
What is the digestive system?The digestive system may be defined as a type of body system that significantly contains organs that take in food and liquids and break them down into substances that the body can use for energy, growth, and tissue repair. This system actively breaks down food components into simpler substances.
Each organ of the body system is composed of a collection of tissues that ultimately derive from cells. Although, the function and structure of each cell are very distinctive when it comes to playing a specific role in complex living organisms, especially human beings.
Therefore, cells in the stomach and large intestine have different, specialized structures and functions is the statement that is true about the cells in the digestive system. Thus, the correct option for this question is C.

How much oil could be saved if home temperatures were lowered by six degrees?
Oils are lipids which are soluble in organic solvents and insoluble in polar solvents such as water. For saving on heating oil prices is to knock the lowering down temperature a few degrees. The Department of Energy research reports that for every degree cooler we can save between 1-3%.
what is polar and non polar solvent?Polar solvents have large dipole moments because they contain bonds between atoms with different electronegativity, such as hydrogen and oxygen.
Non polar solvents forms bonds between atoms with similar electronegativity, such as hydrogen and carbon.
It is possible to still keep oil heat bill down by looking into weatherproofing home, smartly using an efficient thermostat.

Although both humans and bacteria have ribosomes, streptomycin—which blocks ribosome function—does not harm a human who ingests it. Why?.
Streptomycin does not harm a human who ingests it because bacteria have different ribosomal units.
What is a ribosome?Ribosomes are organelles used by cells to synthesize proteins, it is for that reason that they are called protein factories.
Ribosomal units are different in eukaryotic cells (e.g. human cells) compared to prokaryotic cells and they do not bind to streptomycin in eukaryotes.
