Prior to 1900, sea levels rose at maximum, 4 cm per year. Since 1900 sea levels have risen 11 cm per year.
<h3>How sea level is measured?</h3>
- Tide stations and satellite laser altimeters are the main tools used to measure sea level.
- The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
- NASA uses satellites to measure sea level all over the world.
- Height of the ocean's surface, often known as sea level, is measured by the Jason-3 satellite using radio waves and other equipment.
- It studies how the global sea level is changing over time for the entire Earth every 10 days.
- The average sea level is 6,371.001 km (3,958.756 mi), and it is 6,356.752 km (3,949.903 mi) at the poles.

Because mutations do not always result in an amino acid change.
Answer:
Tubules?
Explanation
The trachea, spiracle, and air sac are part of their respiratory system, Howeber, the tubules are what take away the carbon dioxide from their system. Im not sure if they produce the carbon dioixde. But they are a part of what removes the carbon-dioxide from their body.
The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.
<h3>What is Allelic frequency?</h3>
The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.
The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:
2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.
∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.
The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.
Therefore, it is well described above.

Changes in groups of organisms over time produce variations in a population. This relates to both macroevolution and microevolution.
These are evolutions within a small group or a population and across the whole species.
