Answer:
The main sequence stretching from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) dominates the HR diagram. It is here that stars spend about 90% of their lives burning hydrogen into helium in their cores. Main sequence stars have a Morgan-Keenan luminosity class labelled V.

Answer:
the cell membrane is the semi-permeable protective cover that keeps the cell held together. the cytoplasm is semi-fluid within the cell membrane that keeps the cell in shape.

Answer:
Frequency of B allele is 0.6681
Explanation:
If p represents the frequency of dominant allele and q represents the frequency of recessive allele, according to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Given that number of recessive chestnut horse = 28
Total horses = 226 + 28 = 254
frequency of b² genotype = 28/254 = 0.1102
frequency of recessive b allele = √0.1102 = 0.3319
So, frequency of B allele =
1 - 0.3319 = 0.6681
Hence frequency of B allele is 0.6681
Because we can’t tunnel down, so in order to study the interior layers, we must use indirect methods.
Answer:
The chyme is mixed with pancreatic juice and bile juice in the duodenum.
Explanation:
- Chyme is a mixture of food and digestive juice. The stomach produces digestive juices that are mixed with the bolus (the mixed food after chewing and swallowing) and form chyme.
- Chyme is mixed with bile juice and pancreatic juice in the duodenum. After mixing up with bile, bile juice emulsifies the fats.
