Answer:
An oceanographer study the ocean.
Explanation:
Answer:
alleles of a gene separate from each other during meiosis.
Explanation:
Mendel observed that the F1 expressed only one of the alternative variants (in this case, only rounded seeds appeared), while the other variant (wrinkle) disappeared. Mendel named "dominant" the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named "recessive" the second alternative variant.
Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (R and r) and that the pair separates (<u>segregates</u>) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).
A holdfast is a root-like structure that anchors aquatic sessile organisms, such as seaweed, other sessile algae, stalked crinoids, benthic cnidarians, and sponges, to the substrate.
Potential K- strategists include humans.
K- strategist:
The term "K-selected" or "K-strategist" refers to species whose populations vary at or close to the carrying capacity (K) of the ecosystem in which they live. Compared to r-selected species, K-strategist species have remarkably constant populations and generate relatively few offspring, but those offspring typically grow to be rather big. Lengthy gestation durations of many weeks, slow development (and hence prolonged maternal attention), and long longer lifespans are traits of K-selected species. Additionally, they typically live in ecological groups that are generally stable, including premature or climax forests.
R-strategist:
They are creatures that have high reproduction rates followed by high death rates, resulting in populations with wildly variable numbers, according to the concept of r-selected species (or r-strategist). This term is based on the concept of "r," a variable in the ecology of animal populations that denotes a species' maximal reproductive potential. The populations of r-selected species will be small outside of the mating season. R-selected organisms begin to generate a lot of progeny as soon as reproduction begins.
Therefore it is concluded that the final choice is option C, i.e., humans.
