Answer:
When Avascular Necrosis happens at a joint, the joint surface will collapse.
Explanation:
Avascular necrosis (AVN) is a disorder resulting from a temporary or permanent loss of blood supply to the bone. Blood carries essential nutrients and oxygen to the bones. When the blood supply is disrupted (avascular), a break down (necrosis) to the bone tissues start to occur. The bone can be weakened by and eventually result in its collapse.
A collapse of the joint surface can happen if avascular necrosis happens near a joint, resulting in pain and inflammation (arthritis). AVN is also referred to as osteoradionecrosis, aseptic necrosis, or ischemic bone necrosis.
Answer:
p=0.9
Explanation:
The frequency of the different genotypes is as follows:
- AA = 0.81
- Aa = 0.18
- aa = 0.01
There are 2 alleles for this gene, the dominant allele <em>A</em> appears twice in the homozygous dominant genotype and once in the heterozygous.
Then, the frequency of the <em>A </em>allele, <em>p</em>, can be calculated as:
p= freq(AA) + freq(Aa)/2
p= 0.81 + 0.18/2
p=0.9
Answer:
A sugar is categorized into two types, that is, non-reducing sugar and reducing sugar. A sugar, which exhibits a free ketone or aldehyde and can function as a reducing agent is known as reducing sugar. On the other hand, a non-reducing sugar does not comprise a free ketone or aldehyde group, and it cannot function as a reducing agent. With the help of Fehling's test one can determine the amount of reducing sugars present in a solution.
They capture energy from sunlight and manufacture their own food
Answer:
Evaporation – Evaporation happens when heat from the Sun turns liquid water into water vapor (gas). About 90% of the water in the atmosphere comes from evaporation. Most evaporation occurs in the oceans, because they cover so much of Earth's surface. The sweat evaporates into the air.
