A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.
B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.
(Loxodonta and Mammuthus can also be reversed)
C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.
D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.
Answer:
If limestone reacts with limestone, it can turn into a limestone. The reason behind this formation is that, both substances have the same chemical and physical properties and molecules of limestone have a strong chemical bonds between them so it is difficult to separate them from each other.
Answer:
What are so called breast-cancer genes, are mutations in two genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two), and are also associated with ovaric cancer. According to the question, these genes are present in the popolation despite surgeries and deaths, and asks why. Surgeries does not eliminate the genes, they eliminate the tumors, and people can still reproduce after that. And also, most people already had offspring before they know they have cancer, so they are inheriting the mutations on the genes anyway.
Explanation:
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
