Estuaries, often reffered to as the nurseries of the sea provide feedind habitats for many aquatic animals and plants. Fish and shellfish commonly eaten in the U.S such as oyesters and Salmon complete almost half of their lifecycles in estuaries. Due to its shallow water,Pamlico estuary especially provides opportunities such as Fishing, crabbing and watersports as well.
We can be able to determine this concept by basing our facts on two concepts. Nutrient Influx, upon reaching the estuarian ecosystem, the nutrients in the presence of sunlight undergoes photosynthesis and produce phytoplanktons. Basically, where there is sunlight, we can assume there is a nutrient influx. Presence of Phytoplanktons will in turn help attract animals such as fish. Also, another contribution of nutrient influx is manure produced by the animals
Sewage treatment plans and fertilizer runoff. Auto emissions of nitrogen, fertilizers applied on golf courses and home gardens can contribute. Some plankton species may produce toxins that might cause these outbreaks
Answer:
The genotype for each of the parents must be
parent 1 : Gg
parent 2 : Gg
Explanation:
Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.
Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross
G g
G GG Gg
g Gg gg
from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).
Answer:
This question lacks options, options are:
A) histamine
B) gastrin
C) secretin
D) ACh
The correct answer is C.
Hormones or paracrines that inhibit gastric secretion include <u>secretin
</u>.
Explanation:
Hormones pass into the blood that waters the digestive system, go to the heart, circulate through the arteries and return to the digestive system, where they stimulate the production of digestive juices. The hormones that control digestion are gastrin, secretin and cholecystokinin. Secretin is stimulated by intestinal acid at the duodenal level. Its effect inhibits gastric acid secretion, prostaglandin secretion and via somatostatin release. It decreases gastric emptying and stimulates bile and pancreatic bicarbonate secretion.
