<span>b. Exercise
If we conduct a research investigation in these given situation. More specifically, an experiment this would suggest a most probable scenario of a cause and effect situation or technically called causality.
Here the Independent variable is the exercise
The dependent variable is the endurance.
Hence regular EXERCISE increases endurance. </span>
Answer:
(a) Allow movement in only one plane/direction (that is extension or flexion)
(b) The skeletal system also produces blood cells in their bone marrow
Phagocytosis and the inflammatory response. Macrophages are a cornerstone of the innate immune system. ... Recent work indicates that Toll-like receptors play a key role in reading a "bar code" on invading microorganisms and in eliciting a specific immune respone.
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.
bacteria are classified into 5 groups, spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes).
