Hutton: created the idea that a (water erosion basically)continuing process formed and destroyed the rocks and soils of the Earth and that the process was a never ending loop.
Hutton laid the conceptual foundation for uniformitarianism geology
Lyell: added names and ages to the different layers of rocks
Lyell built the structure of geology upon that foundation
Restriction enzymes are DNA cutting enzymes found within bacteria. They can cut the DNA molecule.
Answer:
50%
Explanation:
Let's assume that the allele "T" gives the normal phenotype while the recessive allele "t" imparts the disease and is lethal in homozygous condition. The genotype of each of the two carrier parents would be "Tt". A cross between Tt and Tt would give the progeny in the following genotype ratio=
Tt x Tt= 1/4 TT: 1/2 Tt: 1/4 tt
Therefore, 1/2 or 50% progeny would be the carrier for the Tay-Sachs disease.
Oxygen entered the Earth's atmosphere after the appearance of the Great Oxidation Event (Great Oxygenation Event). The Great Oxidation is the first mass extinction on Earth.
The Great Oxidation lasted 2.4 to 2.0 billion years ago.
Oxygen appeared on Earth thanks to cyanobacteria using photosynthesis.
Answer:
Connective tissue that are found in muscle are of 3 types-Endomysium,Perimysium and epimysium.
Explanation:
Endomysium is called as areolar connective tissue that have nerve and capillaries.
It attaches with epimysium and perimysium and form collagen fibers of tendons.
Perimysium is a sheath of connective tissue that transmit lateral contractile movement.
Epimysium is the layer that is formed by irregular connective tissue .
This layer covers the muscle and provide protection from friction against muscle and bone.
This layer contain fascia and other connective tissue.
