find the area of each triangle
Answer:
First you need the Formula of ( LXW X 1/2 = A)
Explanation:
For the first triangle we have a length of 8 and a width of 8. So we multiply
8 X 8=6464 X 1/2 = 32Hence Triangle 1 Equals 32Yd^2TRIANGLE 2
6 X 5=3030 X 1/2 = 15Hence Area= 15ft ^2TRIANGLE 3
10 X 8 =8080 X 1/2=40Hence Area is 40in^2Why do methane is a gas at room temperature and water is a liquid, even though both molecules are similar in size and mass?
Please help
Answer:
Water can hydrogen bond.
Explanation:
Liquids become gases once they are heated to a certain temperature. Heat is a form of energy. This change occurs when the intermolecular forces between the liquid molecules are energized enough to break. This breakage is necessary because gaseous molecules exist individually and do not interact with one another. That being said, it takes more heat to boil water because its intermolecular forces are stronger than methanes.
Intermolecular forces (IMF) are a result of partial charges on the molecular atoms that cause temporary bonds to form between molecules.
Methane is a nonpolar molecule, meaning each atom can only have slight partial charges. The strongest IMF methane participates in are London Dispersion Forces.
Water, however, is a polar molecule, with the hydrogens having strong partial positive charges and the oxygens having strong partial negative charges. This allows water to participate in a very strong IMF called hydrogen bonding. Again, because these partial charges are so strong, the water molecules can form stronger IMFs.
*When molecules have stronger IMFs, they require more energy(heat) to overcome them.*

ATP acts as a structural sugar in the cell walls of plants.
DNA provides energy for chemical reactions in the cell.
The main function of ATP molecule is to serve as an energy supply in the biochemical reactions that occur in an organism, while the function of DNA molecule is to contain the hereditary genetic information of an organism.
DNA is the base macromolecule of heredity, it is a nucleic acid that contains information on the hereditary characteristics of each living being.
ATP is a nucleotide-type organic molecule that is the universal chemical energy transporter in all cells.
DNA is responsible for storing all the genetic information of the individual, that is, the instructions for the synthesis of all the proteins that make up the body.
ATP is a fundamental molecule for various vital processes, since it is the main source of energy for the synthesis of complex macromolecules, such as DNA, RNA or proteins.
Therefore, we can conclude that ATP is a nucleotide that is essential for cells to obtain energy, while DNA presents the genetic information that living beings use to function.

The statement which best compares is ATP and DNA is that ATP provides energy while DNA carries genetic information.
What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

Ras is a GTP-binding protein that is often defective in cancer cells. A common mutation found in cancer cells causes Ras to behave as though it were bound to GTP all the time, which will cause cells to divide inappropriately. From this description, the normal Ras gene is a/an
From this description, the normal Ras gene is normal Ras gene is a proto-oncogene.
Proto-oncogenes are normal genes involved in regulating cell growth and division. They play essential roles in cellular processes, including signal transduction pathways that control cell proliferation, differentiation, and survival.
However, when certain mutations or alterations occur in proto-oncogenes, they can become oncogenes, promoting uncontrolled cell growth and contributing to the development of cancer.
In the case of Ras, it is a proto-oncogene that codes for the Ras protein.
Thus, the Ras protein is a GTP-binding protein that acts as a molecular switch in intracellular signaling pathways, relaying signals from cell surface receptors to the nucleus.
