Answer:
The correct option is: e. molecules move across the plasma membrane against their concentration gradient
Explanation:
Active transport refers to the <u>movement of the particles or molecules from higher concentration to lower concentration, across the plasma membrane of a cell.</u> This transport requires cellular energy as the movement of the molecules is <u>against the concentration gradient</u>.
Active transport can be divided into primary and secondary active transport.
That evolution could not possibly happen in such a short period of time, but instead occurs over long amounts of time such as billions of years. Also, we did not come from monkeys we have common ancestors with them.
Answer:
In a population, a specific gene has two alleles, 'A' and 'a.' Individuals with
genotype 'aa' die in early childhood. Individuals with genotype 'Aa' have a
higher rate of surviving and reproducing than individuals with genotype 'AA.'
This phenomenon is called survival of the fittest, Darwins law which entails the fittest organisms survives while the ones that could not would go into extinction
Explanation:
There will be 68 Amino Acids in the Protein produced. In translation, the RNA is read in groups of 3 bases. These three bases are called codons, and the complimentary bases are called anti-codons. Therefore, if we have 204 bases, then 204/3 bases in a codon = 68 codons. Each codon codes for an Amino Acid, so 68 codons results in 68 Amino Acids in the resulting protein.
