Answer:
Seeds and fruits are formed by fertilization. In angiosperms, two structures are formed as a result of double fertilization – a diploid zygote and a triploid primary endosperm cell. The zygote develops into an embryo, whereas, the endosperm cell gives rise to endosperm. It provides nourishment to the growing embryo. Both fruits and seeds are an important part of angiosperms...
Hope it helps XD...
Answer:
c. All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes
Explanation:
When genes are linked they do not assort independently. Instead, the alleles on the parental chromosome will have a tendency to migrate together to the same pole of the cell. To produce gametes with genotypes different than the parentals crossing over must happen between the genes of homologous chromosomes during meiosis. However, recombination is a rare event, so the recombinant gametes will be less frequent than the parentals (those that arise when no recombination occurs between genes) and for that reason a greater proportion of the offspring will have parental phenotypes.
Answer:
<u><em>The carbon cycle is the process by which energy flows among all living and non-living things on our planet. </em></u><em>The fact that this process occurs is important for the renewal of nutrients used by animals, plants, and other organisms.</em>
<em />
<em>A way to picture this process is considering that those carbon atoms build up molecules like DNA and hydrocarbons, which are eventually used to form these molecules in other species, in for of energy or sugar, for example, they obtain from food, like leaves, fruits, or other animals consumed.</em>
<em />
<em>The burning of fossil fuels derived from carbon sinks, like petroleum, results in an increased temperature in the oceans since the process of combustion produce CO and CO2 as subproducts, which eventually will end up diffusing in the water, acidifying it and heating it up.</em>
