zalisa [80]

Answer: C. The species is classified in a clade that does not include all protists.

The Kingdom Protists involves organisms which are simple in structure and functions. Some of these organisms have characteristics common to both plants and animals. A clade represents a group of organisms that have all characteristics common to their ancestor. The example of algea given here, has characteristics which are found mainly in plants belongs to Kingdom Plantea. Therefore, the clade of these Protists can be related with those of plants but cannot be related to Protists which exhibit animal like characteristics.  

Therefore, species is classified in a clade that does not include all Protists.

Which one of the following nucleotide pairs would be found in a DNA molecule?
MrRa [10]

Guanine-cytosine is one of the  nucleotide pairs that would be found in a DNA molecule. The other is Adenine- Thiamine.

Explanation:

Pyrine bases – Adenine & Guanine-  pair with pyrimidines bases – Cytosine and Thiamine. Adenine pairs with Thiamine while Cytosine pairs with Guanine.

In RNA, however, while this same principle of base pairing is observed, rather than Thinmaine, RNA has Uracil in its place. Therefore, in RNA, Adenine pairs with Uracil. There is no Thiamine in RNA.

How do the three types of colorblindness differ in genotype and phenotype?
vfiekz [6]

Normal colour vision (trichromacy) refers to vision that uses all three types of light cones. People with defected trichromatic vision will be colour blind to some extent and these conditions are called anomalous trichromacy. Three types anomalous trichromacy ( one type of cone perceives light slightly) :

1. Protanomaly – phenotype: reduced sensitivity to red light

2. Deuteranomaly  - phenotype:  reduced sensitivity to green light

3. Tritanomaly – phenotype: reduced sensitivity to blue  

People can also have color blindess as the result of mutation, when loss of function of one cone occurs. This condition is called dichromacy. If there is complete color blindness or monochromacy, the person can’t distinguish any color from grey.

Color blindness is an inherited genetic disorder resulted from mutations on the X chromosome.
