From the information given, the lab cart has a mass of 0.5 kg and the student exerts a force of 3N on it.
We use the formula F = MV
Where F = Force, M = mass and V = velocity
In our case, F = 3N (or 3 Kg m/s²) , M= 0.5 kg , V is unknown.
F= MV → MV = F → V = F / M
V = 3 kg m/s² / 0.5 kg
V= 3 / 0.5
V = 6 m/s²
Therefore the acceleration of the cart 6 m/s²
Yes I would say you could use a punnet square

in 2015 solar employment had overtaken oil and gas as well as employment in the U.S.
Answer:
chloroplasts and mitochondria.
Explanation:
Chloroplasts and mitochondria are the organelles capable of ATP production by photophosphorylation and oxidative phosphorylation respectively. Chloroplasts are the site for photosynthesis. The light reactions of photosynthesis include splitting of the water molecule in presence of sunlight and transfer of electrons from PS-II to PS-I via electron carrier. During electron transport, a proton gradient is created which in turn drives ATP synthesis.
Mitochondria are the site for aerobic stages of cellular respiration. Glycolysis and Kreb's cycle, the first and second stages of cellular respiration produce NADH and FADH2 during the redox reactions. These reducing powers are oxidized by giving their electrons to the terminal electron acceptor, the oxygen molecule.
Electrons from the reducing powers are carried to oxygen molecules via a series of electron carrier proteins embedded in the inner mitochondrial membrane. During electron transport, an electrochemical gradient is created which in turn drives the ATP synthesis.
Answer
The various steps in the transcription and translation process of protein synthesis are described below.
Explanation:
Proteins (made up of amino acids) have an important role in the various functioning process of an organism. Protein synthesis which takes place in the cells of an organism consists of two major processes: transcription (DNA to RNA) and translation (RNA to protein).
Transcription: It is the first process in protein synthesis which occurs in the cell nucleus where a single-stranded messenger RNA (mRNA) is created using a DNA strand and the genetic instructions in DNA are transferred to this mRNA. The steps in transcription are initiation, elongation, and termination. The beginning process known as initiation occurs when an enzyme RNA polymerase binds to a promoter (region of a gene) and the DNA unwinds. One of the DNA strands acts as a template and the enzyme reads the bases in the template DNA strand.
The next step is elongation, where the RNA polymerase builds a strand of mRNA by the addition of nucleotides using complementary base pairs. Here, adenine (A) in the DNA binds to uracil (U) in the RNA. Termination is the last step in which the transcription process ends when the RNA polymerase comes across a termination sequence in the gene. Thus, the completed single-stranded mRNA detaches from DNA.
Translation: It is the second process in protein synthesis which occurs in the ribosome of the cell where the genetic information in mRNA is used to create a protein from amino acids. A triplet of nucleotides is called a codon and they define amino acids. There are 64 possible codons and the codon, AUG acts as the start codon which initiates translation in addition to specifying the amino acid methionine. In the initiation step, the first amino acid in the polypeptide chain is brought by transfer RNAs (tRNAs) to bind to the start codon of mRNA. During elongation, each type of tRNAs in the cytoplasm bound to a specific codon on the mRNA template and adds the corresponding amino acid to the polypeptide chain. Stop codons (UAA, UAG, or UGA) terminate protein synthesis and release the polypeptide.
