Explanation:
Excess energy from food is stored as adipose tissue in the body. Fats are critical for maintaining body temperature, cushioning vital organs, regulating hormones, transmitting nerve impulses, and storing memory. Lipids transport fat-soluble nutrients and phytochemicals and promote bioavailability of these compounds.
Explanation:
To protect the animals, plants, and more. Without having the habitats they'll die/go extinct. The plants will soon rot/wither away.
Answer:
No, there are multiple ways in which different mutations in the same gene can cause the same phenotype
Explanation:
Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)
These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.
- There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)
- The entire gene could be deleted
- A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein
- There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.
There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.
For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.
Explanation:
The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.
The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.
Some elements of the contour lines or that go with them to give better representation are:
- black dots (representing a top)
- thicker lines (every fifth, so that the counting is faster and easier)
- small lines with given direction (representing cliffs or highly steep slopes)
- numbers (providing information about elevation)
