Answer:
Nonsense mutation: it causes a premature stop codon, so the protein cannot be fully synthesized.
Missense mutation: it causes change on the aminoacid encoded, so it can cause a change in the protein structure if the new aminoacid doesn't have the same chemichal properties as the original.
Synonymous (silent) mutation: it causes no change, the same aminoacid is encoded.
Single nucleotide insertion or deletion: changes the entire structure of the protein because it shifts the reading frame.
Three nucleotide deletion: one aminoacid will no longer be part of the protein, if this aminoacid was located, for example, on the active site of an enzyme, the protein could lose its function.
Chromosomal translocation: it can break a gene in two, causing the protein to no longer be able to be synthesized, or it can change the transcription regulation because it is now under the effect of other regulating sites that result in a different transcription pattern.
If the cell is green, that would mean that it contains the pigment of chlorophyll (suggesting that it is a plant cell). In addition, a rigid cell wall means the cell is part of a stronger structure, so it is likely a plant cell.
Photosynthesis
the equation is- Carbon dioxide + water = oxygen + glucose
Answer: Insects create the biological foundation for all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, and provide a major food source for other taxa
Facts about insects: Insects are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae.
The correct answer is option B. shown that the tidal forces needed to move continents would stop Earth’s rotation.
The Wegener’s idea that tidal forces might cause continental drift suggested that the tidal force and the centrifugal forces on the earth was the cause of the movement of the plates.
But, he was unable to propose the mechanism of such movement. Also, if the centrifugal force of the earth would move the plates apart, then the earth below it should remain stationary, but the earth is in continuous rotation, so, this idea was not acceptable, as it is would stop rotation of earth.
