Answer: The cross will produce 4 offsprings with the following genotypes:
XhXh, XhX, XhY and XY.
Explanation: Hemophilia is an X-linked disease. A woman who carries the hemophilia gene but doesn't not express it is heterozygous, therefore she has a genotype of XhX, and a man who has hemophilia has a genotype of XhY. A cross between them will produce one female and one male who are hemophilic (XhXh and XhY), one female who is a carrier (XhX) and one normal male.
See the punnett square attached for the cross
Answer:
The correct answer is myofibrils
Explanation:
The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.
<span>An animal with these such features would be well suited to live in environment like the rain forest. Its long limbs and tail would allow it to swing from tree to tree, and also reach up into the trees to gather food. The hand-like paws would make climbing easier, and allow the animals to grab food from higher places.</span>
