Answer:
See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome
Explanation:
According to the position of the centromere, chromosomes can be of 4 types namely:
- Metacentric
- Acrocentric
- Telocentric
- Sub-metacentric
A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.
Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.
Telocentric chromosomes have their centromeres at one end of the chromosome.
Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.
The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.
Answer:
Cross bridge in a sarcomere of a fast fiber produce higher amounts of force as compared to a cross bridge in a sarcomere of a slow fiber
Explanation:
When a muscle contracts, a cross bridge is formed between actin and myosin. The sarcomere shortens when a muscle contracts by reforming cross bridge. In general a muscle fiber is of three types – a) slow, b) Fast and c) intermediate.
The sarcomere of fast fiber generates high force but for a short period of time. On the other hand, sarcomere of slow fiber generate lower amounts of force but this force lasts for a longer period of time. Due to this difference, fast fibers are the predominant fibers in the body
The second option since the fermentation occurs best at that temperature and you can narrow down a more precise temperature.
Strong collagenous fibers, known as Sharpey’s fibers, connect the periosteum to the bone surface. This fiber extends to the bone’s circumferential (outer part) and interstitial lamellae (inner). It’s specifically made up of a fibrous layer (outside) and a cambium layer (inside).
The difference between pH 3 and pH 4 is a 10 fold difference in the concentration of H+
