B. 3 base codon one the bottom, Amino acid attachment site on top, phosphate groups on the left and right sides
C.3 base codon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
D. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
Answers
Answer:
the answer is D 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
Explanation:
idfk know man, but thats the answer!
The option that correctly describes the tRNA's structure is D. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
tRNA stands for transfer ribonucleic acid. It interacts with the mRNA and aminoacids being a key element in protein synthesis.
The tRNA structure is:
Three base anticodon, one on the tRNA's bottom. They are three nucleotides that interact with a complementary mRNA codon. An amino acid attachment site on top where the specific amino acid for the anticodon attaches, later on, in the ribosome, together with the codon in the mRNA it adds the amino acid to the forming protein.Hydrogen bonds between tARN bases. These bonds give the tRNA its characteristic shape.In conclusion, the tRNA structure is anticodons, an amino acid attachment site on top, and hydrogen bonds between the bases.

What are some advantages to being unicellular? Multicellular?
Answers
As a unicellular, you’ll be able to reproduce very quickly and you won’t need a complicated organ system. Being smaller in size can be an advantage of being a unicellular organism.
And as a multicellular, you’ll have competitive advantages of increasing in size without having limitations. They can have longer lifespans when individual cells die.

Describe using scientific terms, how plants turn sunlight into energy? Make sure to refer to chemical equation to photosynthesis and discus the reactants and products.
Answers
Answer:
Explanation:
Photosynthesis is the process plants use to convert sunlight into energy. Oxygen is produced as by-product of photosynthesis when the water absorbed by plants is 'split'. It is one of the most important reactions on the planet because it is the source of nearly all of the world's oxygen.
Answer:
- Possible Answer #1: The chemical process that coverts sunlight into energy is called photosynthesis. This is represented with the equation 6CO2 + 6H2O → C6H12O6 + 6O2. (Carbon dioxide + water + a source of light energy = oxygen and glucose. Using the pigment chlorophyll found in plant cells, the plant is able to produce glucose (the main source of ATP) by developing both carbon dioxide, water, and light energy into products that help support the cell's function. Oxygen is the waste product excreted by the plant as a direct result of photosynthesis itself.

Composting, or controlled decomposition, requires a proper balance of “green” organic materials and “brown” organic materials. “Green” organic material includes grass clippings, food scraps, and manure, which contain large amounts of nitrogen. “Brown” organic materials includes dry leaves, wood chips, and branches, which contain large amounts of carbon but little nitrogen.

Answers
Answer:
A: gene flow
Explanation:
have a nice day
The notes describe gene flow. Therefore, option (A) is correct.
What is gene flow?Gene flow is the transfer or exchange of genetic material, specifically genes, between different populations of the same species. It occurs when individuals from one population migrate or disperse to another population and successfully reproduce, introducing their genes into the gene pool of the receiving population.
Gene flow can happen through various means, such as the movement of individuals, migration, or the dispersal of pollen or seeds. It is an important mechanism in evolution as it facilitates the transfer of genetic variation between populations. By introducing new genetic material, gene flow can increase genetic diversity within a population and reduce genetic differences between populations.
Gene flow can have significant impacts on the genetic makeup of populations, influencing their adaptability, genetic structure, and evolutionary trajectories. It can counteract the effects of genetic drift and natural selection, promoting the sharing of beneficial.

Answer:
D. A segment of DNA molecule
Explanation:
Gene is a segment of a DNA molecule that holds instruction needed for the synthesis of useful products (protein). Ideally, DNA is the storage material of genetic information in a cell. The DNA harbors the GENE, which itself is being expressed in order to use the information contained in it to produce useful products responsible for the phenotype of an organism.
A gene contains sequences made up of nucleotide bases that determines the sequence of amino acids to be produced, and ultimately the type of protein.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs , "light", and sunthesis , "putting together". In most cases, oxygen is also released as a waste product. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Answers
Answer:
Explanation:
Carbon fixation in different temperatures can be clearly seen in the graph.
Explanation:
a) Above the optimum temperature, the increasing in environmental temperatures decreases the carbon fixation. This is because rubisco is an enzyme, a protein, and proteins tend to loose function at high temperatures due to getting close or even reaching denaturation.
b) Carbon fixation in different temperatures can be clearly seen in the graph. We can see how the rates go down as the temperature passes the optimal temperature.
c) The plants produce caarbohydrates due to a good carbon fixation, so we have to look at the worst carbon fixation rates in the graph. The lowest amount of carbogydrates will occur at temperatures around 50°C. Based on the knowledge we have about protein denaturation, we could even say temperatures above 50°C will show even lower carbohydrate production.

Pterosaur bones were hollow and air-filled, like the bones of birds. They had a keeled breastbone that was developed for the attachment of flight muscles and an enlarged brain that shows specialised features associated with flight.
