Answer: the steel wool in the 3.0 M HCl reacts fastest.
Explanation:
Answer:
The microorganism creates its own energy.
Explanation:
Based on the pattern of nutrition, a living organism can either be autotrophic or heterotrophic. Autotrophic organisms are those organisms capable of synthesizing its own food or energy source using light (photosynthesis) or chemicals (chemosynthesis). Heterotrophs, on the other hand, cannot synthesize their own food, hence, they depend on other organisms for energy.
According to this question, a researcher claims that a newly discovered microorganism is an autotroph. For this claim to be true, this means that the microorganism must be capable of CREATING ITS OWN FOOD/ENERGY either by photosynthesis (light) or chemosynthesis (inorganic chemicals).
Answer:
Ribosomal RNA: Structural part of ribosomes
Messenger RNA: Carry genetic information from DNA to proteins
Transfer RNA (tRNA): Transport amino acids to protein synthesizing complex.
Explanation:
Ribosomes are made up of ribosomal RNA (rRNA) and proteins. The catalytic activity for the formation of peptide bonds between amino acids during protein synthesis resides the RNA of ribosomes.
Messenger RNA (mRNA) is formed by the process of transcription during which the nucleotide sequence of the template DNA strand is copied into that of the RNA. The mRNA serves as a template for protein synthesis. The nucleotide sequence of mRNA is read in the form of genetic codes to specify the amino acid sequence of a protein. In this way, the genetic information stored in DNA is carried to the proteins.
During the process of protein synthesis, tRNAs carry amino acids to the mRNA-ribosome complex so that the amino acids are incorporated into the polypeptide. For the purpose, there is a tRNA with a specific anticodon sequence for a particular amino acid.
I am pretty sure the answer is increase and increase. Because enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes.
Answer:
M phase: 4.8 hr
Prophase: 2.4 hr
Prometaphase: 0.72 hr
Metaphase: 0.24 hr
Anaphase: 0.84 hr
Telophase: 0.6 hr
Explanation:
Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:
M phase: 40/200 = 0.2 x 24 hr = 4.8 hr
Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr
Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr
Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr
Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr
Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
