Answer:
Living things are classified into groups that start out large and become more specific in a system of classification called taxonomy. Scientists classify living things at eight different levels: domain, kingdom, phylum, class, order, family, genus, and species.
Explanation:
In carbon dioxide (CO2), there are two oxygen atoms for each carbon atom. Each oxygen atom forms a double bond with carbon, so the molecule contains two sets of double bonds. Two sets of double bonds means that the total number of electrons being shared in the molecule is two. four. six. eight.
Answer:
Eight
Explanation:
In a single bond there are 2 electrons
In a double bond there are 4 electrons
Two double bonds = 8 electrons
Answer:the answer would be eight hope this helps

Researchers identify a gene in cockroaches that is responsible for their ability of nerve regeneration. How might it be possible for this gene to be used in treating human paralysis?
This gene could be analyzed to determine its homology level with a human gene, which then could be restored in its normal expression. This strategy can restore the normal phenotype in defective human cells.
Sequence homology, which refers to the level of evolutionary relationship among genetic or proteins sequences, is a fundamental subject matter to determine gene function.
From this approach (sequence homology search), researchers can identify valuable genes involved in diseases in which the restoration of their normal expression levels can be used to restore the normal phenotype in defective cells.
In this case, the identification of a gene in cockroaches that is responsible for nerve regeneration could be used for subsequent identification of a human homologous gene sequence, which then can be restored in order to treat human paralysis.

Which RNA molecule is involved in translating a short sequence of RNA into an amino acid, acting like a molecular Rosetta stone?
a
snRNA
b
tRNA
c
mRNA
d
rRNA
Given what we know about the translation process, we can confirm that the RNA in question that aids in the process of translating a short sequence of RNA into an amino acid is mRNA.
mRNA is referred to as messenger RNA. This RNA molecule acts as just that, a messenger carrying the necessary code to create amino acids and therefore, proteins. This messenger binds itself to the ribosomes of a cell, which are in charge of reading the code, one codon at a time, and chaining together the corresponding amino acids.

Which method of timber harvesting removes all trees from the harvest area?
How does one distinguish
between the left & right
sides of a heart?
Answer:
See explanation section for answer:
Explanation:
The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.
Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.

If each of these food chains start with 10,000 grams of phytoplankton, how much reaches the highest trophic level in each food chain
Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.
Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.
Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.
For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.

Which side will gain water
What is c ?
Answer:
1-b
2-b
3-phospholipid bilayer
B side is hypertonic. It will gain water. C is Phospholipid layer.
What is Hypotonic Solution?
A hypotonic solution is a type of solution that has a lower osmotic pressure than any other solution to which it is compared. It is a solution in which a small amount of solute passes across a semipermeable membrane compared to the amount of solute in the other solution.
If the solute concentration outside the cell is lower than inside the cell, these solutes cannot cross the membrane, so the solution is hypotonic to the cell.
The cell membrane consists of a phospholipid bilayer containing embedded proteins present between these two solutions where a hypotonic solution has a relatively low concentration of solutes.
Thus, B side is hypertonic. It will gain water. C is Phospholipid layer.
