Answer:
Nucleic Acids are precursor for Proteins.
Explanation:
Proteins are formed( protein units called amino acids) by the decoding of specific nucleic acids to give specific Proteins.
No nucleic acids don't provide energy, these are building block of genetic material (DNA). While Proteins provide energy.
No proteins don't carry genetic information.
Yes structure of protein is determined by nucleic acids because each nucleic acids code fir specific unit of amino acid which join to form protein.
No subunits of nucleic acids are nucleotides where as subunits of Proteins are called amino acids.
Please mark it branliest if the answer is little bit satisfying.
This has something to do with winter seasons. You see, during winter days, <span>the sun is further down in the sky, so the same circle of sunlight covers a wider area, so there is less light per plant. In this case, those plants that are pointing straight at the sun have higher chances of growing better. Hope this answers your question.</span>
The type of microscope that <span>can produce three-dimensional images of a cell’s surface is the electron-scanning microscope. In this type, beam of high-energy electrons is focused to project the correct projection of the cells. The projection of the cells are made up of signals of the surface.</span>
Answer:
The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.
Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.
The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs. The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.
In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.
This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.
