In sedimentary rocks, the bottom layers are older that overlaying layers. This is because sediments are placed on top of each other by surface runoffs to ocean beds. Therefore, the first sediments to be deposited will always be towards the bottom as more and newer ones are brought in and deposited.
Answer:
Species that are <u>sympatric</u> species can occur in the same location and are phenotypically different.
Explanation:
Speciation is the evolutionary process by which a population of a species acquires differentiating characteristics that lead it to distinguish itself from the species it formed. Sympatric speciation is a type of speciation that consists of the genetic separation of different populations of the same species that live in the same environment (same geographical location), so that species originate by divergence between individuals, that is, they diversify due to to the appearance of isolation mechanisms these can be genetic, ethological or sexual.
<span>I think you might be asking about the 3 different osmotic conditions a cell might find itself in. Isotonic is the normal cell environment where water moves in and out of the cell freely and equally in both directions. It is in osmotic equilibrium so to speak. The concentration of water and solutes is equal on both sides of the cello membrane. In a hypotonic solution the cell will gain water and swell up -...</span>
True I think the answer is true
Pink snapdragons are a result of incomplete dominance. Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant. The fruit color of eggplants is another example of incomplete dominance.
