Protozoans, bacteria, fungi... viruses are not organisms
Answer: p (short hair) = 0.91 and q (long hair) = 0.09
Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.
For this question, short hair is allele L and long hair is allele l
So, the frequency of short hair is p and of long hair is q.
To calculate the frequencies:
Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)
p = 182/200 = 0.91
The same formula goes for the recessive allele, so:
q = 18/200 = 0.09
Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
Answer:
D) Jaws and paired appendages
Explanation:
Jaws provided the ability to churn and grind food, while paired appendages enabled various locomotive methods such as running, walking, hopping, etc.
Answer:
Wind and water
Explanation:
For plants, Darwin came to the conclusion that spores, seeds, pollen, etc were blown over from the mainland.
For animals, Darwin theorized that the ancestors of the Galapagos animals were carried over on storm debris during a hurricane or something of the like.
(birds simply just flew over)
Answer:
True
Explanation:
Diffusion is the movement of particles from areas of high concentration to areas of lower concentration. This is described as a movement with the concentration gradient.
