Biology

Fudgin [204]3 years ago

Gene is a sequence of nucleotides on the DNA that determines a certain trait. When the gene mutates, it takes up two or more forms. These forms are called the alleles. Example, in the pea plant, a gene codes for the color of the pea. This gene exists in two forms, one gives yellow color to the peas and the other gives green color to the peas. The two forms can be present together in the genome. Their expression will determine the dominance of one form over the other (in this case yellow color is dominant over the green color).

A person's genotype can be guessed but not accurately estimated by looking at the phenotype. A phenotype can be a result of the action of two or more genes expressing together. Though a pedigree analysis on the inheritance of certain kinds of genes can reveal the mode of inheritance, i.e., if its autosomal gene inheritance or sexually-linked gene inheritance.

Answers questions . why are estuaries, such as the pamlico estuary, so important? . how would you be able to determine from whe
GaryK [48]
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

which one of the plants pictured below was given water mixed with salt, and which one was given pure water? Explain how you know
ludmilkaskok [199]

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.

<h3>Osmosis</h3>

Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.

The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.

On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.
