Polydactyly is a trait found in cats and humans in which a person (or cat) has 6 digits per
hand or paw. The allele for polydactyly is rare but dominant. If a man who is heterozygous
for this trait marries a woman with 5 fingers, what are the chances that they will have a child
with polydactyly?
Answers
Answer:
1/2 or 50%
Explanation:
This question involves a single gene coding for the number of digits per paw in cats or humans. The allele for polydactyly i.e six digits (P) is dominant over the allele for normal number of digits i.e 5 (p).
According to this question, If a man who is heterozygous (Pp) for this trait marries a woman with 5 fingers (pp), the following gametes will be produced by each parent:
Pp : P and p
pp : p and p
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Pp, Pp, pp and pp
The offsprings with genotype Pp will have polydactyl, hence, the chances that they will have a child with polydactyly is 1/2 or 50%.

Evaluate the pros and cons of using an NPK fertilizer, a natural compost, and lime on a field with substantial amounts of clay and humus and with a low pH of 3, which is to be planted with a legume crop.
Answers
Answer:
Leaching of nutrients occur.
Explanation:
NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.

which organelle does the skeletal system connect to and why?
Answers
Answer:
Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.
Answer:
Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract. Skeletal muscle cells do contain more mitochondria than other cells, because muscle cells require more energy and must convert more glucose. Skeletal muscle cells also differ from other cells because of the myofilaments within the myofibrils. Within these filaments are proteins known as myosin and actin. The special filaments enable the skeletal muscles to contract. The myofibrils within skeletal muscle cells are divided into units known as sarcomeres, which are the units of skeletal muscle cell contraction.

Answers
Answer:

Look at the albino whale people have named Migaloo. The white color is the result of mutations in the genes that code for the proteins responsible for skin color. Is Migaloo’s white color likely to be an advantage in its current environment? Explain your answer.
Answers
No, the white color of Migaloo is not most likely an advantage in its current environment. This is because white is the color that is easily perceived by predators.
What is the Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism. An organism that undergoes an event of mutation is known as a Mutant. The agents of mutation are known as mutagens.
White color is easily perceived by predators as compared to black, brown, grey, etc. So, it somehow reduces the fitness and survivability of Migaloo. This white color is the result of mutations in the genes that code for the proteins responsible for skin color.
Therefore, the white color of Migaloo is not most likely an advantage in its current environment.
