May i have choices but <span>Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure on this trait, the heights of individuals in a population would vary, with most individuals being of an average height and fewer being extremely short or extremely tall. However, when selection pressures act on a trait, this distribution can be altered.</span>
Answer:
eukaryotes
Explanation:
Plants, animals, fungi and protists are all eukaryotes; these organisms are made up of one or more cells with a variety of membrane-bound organelles, including the nucleus — the big boss organelle that contains all the DNA and all the instructions for making that particular bear or ringworm or ficus tree or fruit fly.
Distal Convoluted Tubule and Collecting Duct are parts of the nephron does ADH act on to regulate water reabsorption. ADH acts throughs G-protein coupled receptor in order to increase transcription and the insertion of Aquaporin–2 channels for the apical membrane of the CD and DCT cells. Therefore, the permeability of CD and DCT cells to the water increases.
A Distal Convoluted Tubule (DCT) is a short nephron segment, a portion of kidney nephron between Henle or macula densa and the collecting tubule loop. It plays an important role in regulating extracellular fluid volume and electrolyte homeostasis. In DCT, Sodium absorption occurs, which is mediated by the hormone aldosterone.

Answer:
RNA determines the sequence of amino acids in proteins and polypeptides by a two-step process: transcription of DNA produces mRNA in the nucleus, then translation of the mRNA to tRNA takes place in the ribosome in the cytoplasm. ... The sequence of amino acids was controlled by the information in the molecules
