Answer: Carbon is the most important element in organic compounds, which means that life on earth is possible thanks to this atom and its characteristics. Below you can see some of the ones I consider to be the most relevant

Explanation: Carbon atom has 6 protons and 6 neutrons in its nucleus, and that nucleus is surrounded by 6 electrons. Those electrons are distributed two in their first level (called s) and four in their second level (called p).

It is tetravalent, because it has 4 electrons orbiting its last energy level, which can be combined with other atoms, even with another carbon atom forming covalent bonds. , present in all the organic compounds.

Thanks to these electrons, it can form three hybridizations or types of junctions; single, double or triple. This is important for molecular geometry: the single bond determines the formation of a tetrahedron, with angles of 109.5 ° , the double bond determines the formation of a flat triangular structure, with 120 ° angles and the triple bond determines the formation of a linear structure, with 180.

This are some of the most importan characteristics tha make Carbon a unique element.

If the activation energy required for a chemical reaction were reduced, what would happen to the rate of the reaction?

Ratling [72]

The rate would increase because more molecules would collide at the activation energy, which will cause more molecules to react, and thus it will speed up the reaction rate.

In garden peas, tallness (T) is dominant to shortness (t) and axial flowers (A) are dominant to terminal flowers (a). What are t

Delicious77 [7]

Answer:

The correct answer is explained below:

Explanation:

According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
It produces the following gametes: TA, Ta, tA, ta.
The heterozygous tall, terminal plant has the following genotype: Ttaa
It produces the following gametes: Ta, ta.
Crossing them,

TA Ta tA ta

Ta TTAa TTaa TtAa Ttaa

(Tall, Axillary) (Tall, Terminal) (Tall, Axillary) (Tall, Terminal)

ta TtAa Ttaa ttAa ttaa

(Tall, Axillary) (Tall, Terminal) (Short, Axillary) (Short, Terminal)

The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
The phenotypes obtained are:

Tall, Axillary = 3.
Tall, Terminal = 3.
Short, Axillary = 1.
Short, Terminal = 1.

what impacts is ocean acidification having (or expected to have) on marine life? include at least 3 organisms in your descriptio

Strike441 [17]

Life forms that depend on remineralize shells and skeletons will be harmed by ocean chemistry, as would species that are acid-sensitive and organisms higher in the food chain that eat these sensitive animals.

<h3>An organism is what, then?</h3>

An organism is a collection of molecules working together to form an more or less permanent together that demonstrates the characteristics of life. Definitions in dictionaries frequently use general terms like "any biological entity, such as a plant or animal reproduction."

<h3>What two kinds of organisms are there?</h3>

Prokaryotic and eukaryotic organisms are the two primary categories. These type the cells that form the organism are the basis for this differentiation. Prokaryotic cells have a very basic, rudimentary structure without a nucleus. Additionally, membrane-bound organelles are absent.

bogdanovich [222]

Answer:

By decoding information with the help of transfer RNA (tRNA).

Explanation:

The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.
