Quartz is an important mineral in mafic rocks like basalt and gabbro. The given statement is false.

<h3>What is mafic rocks?</h3>

Mafic minerals and rocks are silicate minerals or igneous rocks that are high in magnesium and iron.

The majority of mafic minerals are darker in color, and some of the most common rock-forming mafic minerals are olivine, pyroxene, amphibole, and biotite. Basalt, diabase, and gabbro are examples of common mafic rocks.

In geology, mafic rock is an igneous rock monopolized by the silicates pyroxene, amphibole, olivine, and mica.

These minerals are rich in magnesium and ferric oxides and contribute to the dark color of mafic rock.

Thus, the given statement is false.

Parkinson's disease prevents the brain from properly sending motor signals to the consciously moved muscles of the body. This di

9966 [12]

Parkinson's I guess would inhibit parts of the synapses which produce or receive neurotransmitter substances such as dopamine or acetylcholine which are required to produces as EPSP excitatory post synaptic potential which is required for the propagation of nerve signals. so signals cant reach the conscious muscles as effectively causing the involuntary shaking of the muscles in people with Parkinson's

hope that helps

(A physical examination of the cats siblings) because you cant check its kittens, because there could be a dominant phenotype that caused them to have short tails. A physical examination of the cat wouldn't help either.

Below is a mature eukaryotic mRNA transcript. Translate this mRNA into a protein, also showing the tRNA anticodons involved. Mak

diamong [38]

Answer:

mRNA ⇒ 5'GMU UAC AUG CGG CUC AGU UGA GGC GAA AAA A 3'

tRNA ⇒ UAC GCC GAG UCA ACU

protein ⇒ N - MET ARG LEU SER Stop - C

Explanation:

In protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.

Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.

The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.

Each of the codons represents one of the 20 amino acids used to build the protein. Each amino acid can be codified by more than one codon. From the total 64 codons, 61 codify amino acids, and one of them is a start codon. The left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule.

• The end codons are UAA, UAG, UGA.

Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.

In the exposed example we have the following mRNA.

mRNA ⇒ 5'GMU UAC AUG CGG CUC AGU UGA GGC GAA AAA A 3'

Codons are separated by a space left between them. AUG is the start codon placed near the 5´ extreme. UGA is the end codon near the 3´ extreme. tRNA will add amino acids from the start codon, not before.

tRNA ⇒ UAC GCC GAG UCA ACU

Anticodons are separated by a space left between them.

protein ⇒ N - MET ARG LEU SER Stop - C

Each mRNA codon codifies for an amino acid. The start codon codifies for methionine. AUG = Met, CGG = Arg, CUC = Leu, AGU = Ser, UGA = Stop codon. The amino terminus is represented as an N and the carboxy terminus is a C. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.

How is energy related to the change of state

Blababa [14]

Answer:

Atoms lose energy as a gas changes to a solid. How is energy related to the change of state represented by the model? Atoms gain energy as a solid changes to a liquid.
