BIG BRAIN ANSWER:
Before Darwin, a naturalist named Jean-Babtiste Lamarck believed that the environment altered the shape of individuals and that these acquired changes were then inherited. Meanwhile, Charles Darwin was a naturalist on a ship called the HMS Beagle, and he discovered that the beak shape varies among finch species in the Galapagos Islands. He found that the beak of an ancestral species of finch had somehow been transported to these islands, and adapted over time to acquire different food sources that were available, causing variation, and that nature just selected for the most suitable beak shape and against less useful ones.
A gene is the set of specific nucleotide sequences, which is present on a chromosome at certain specific places. A gene is responsible for the determination of the traits of any individual. A gene helps in the expression of these traits by the formation of the polypeptides. A gene controls the synthesis of these polypeptides, which then expresses the concerned traits.
Hence, the answer is 'polypeptides'.
Answer:
26: Chloroplast
27: sunlight, carbon dioxide, and water
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
I think correct answer is:
a restriction enzyme
Restriction enzymes cut DNA molecules at a limited number of specific locations, each of which contains a recognition sequence, or restriction site.
Hey there!
The fundamental units of matter are called atoms. All matter, including liquids, solids and gases, are made up of these tiny building blocks.
