Answer:
B) It showed that humans are in the species sapiens.
Explanation:
Cladistics was invented for the purpose of improving on taxonomy and it is a way to deal with biological classification. DNA technology lead to more use of cladistics because it changed ideas about which animals were closely related and also it showed new evolutionary relationships between animals.
Answer:
All of their sons would be colour blind
Explanation:
Given that colour blindness is X linked recessive condition which means that the gene is located on X chromosome and when present in recessive homozygous condition, it will be expressed. Hence if XC is dominant allele and Xc is recessive allele, XcY and XcXc will be colourblind.
The male has normal vision and males have only one X chromosome so his genotype is XCY.
The female is colourblind and females have two X chromosomes so her genotype is XcXc.
Their children:
XC Y
Xc XCXc XcY
Xc XCXc XcY
All the sons have XcY genotype where gene for colourblindness is in recessive condition hence all of their sons would be colourblind.
Answer:
Hey There!
You wanna hear a joke about nitric oxide?

<em><u>NO</u></em></h2>
Answer:
Phosphorus is essential for growth of plants and other organisms. When concentration of phosphorus mostly from high breeding rate e.g., pigs, cattle etc. rise in water it causes severe growth of plants and algae as well as phytoplanktons. As a results layers of phosphorus start to release phosphorus as well due to positive gradient. These reactions in water are iron-redox reactions that are crucial for the release of phosphorus.
When too much phosphorus accumulates, it produces a degrading growth feedback in plants, algae and phytoplanktons that then shift toward excessive nitrogen available from fertilizers and cause a flip from P to N. Cynobacteria now dominates and denitrification as well as nitrification takes place simultaneously.
Severe eutrophication induces hypoxia in water that cause a major damage to plants biodiversity in the environment.
