High quantities of nutrients in water from industrial crop fertilizers and animal waste cause excessive aquatic plant growth — a process known as “eutrophication,” which, in turn, causes “hypoxia,” or water that is low in oxygen. Harmful algal blooms (or HABs) occur when aquatic algae grow rapidly out of control.
Answer:
alleles-one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
dominant- The dominant allele of the gene is inherently dominant,so it hides the presence of the recessive allele
heterozygous-having two different alleles of a particular gene or genes.
homozygous-a particular gene that has identical alleles on both homologous chromosomes
recessive-A recessive gene is a gene that can be masked by a dominant gene
The answer is; B
Sometimes winds carry the sand of the beaches causing erosion. The fences act as breakers of this wind erosion. As wind tries to carry the sand, they encounter the fence and 'break'. Therefore, the sand is deposited along the fence forming a sand dune. These dunes also form protection from storm surges.
Well, the carbon cycle provides an example of matter cycling and energy flow in ecosystems. Photosynthesis, digestion of plant matter, respiration, and decomposition are important components of the carbon cycle, in which carbon is exchanged between the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes.
i think it is the 2nd one
