Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. How high or low is the probabilty that a female child of Charles and Marie would suffer from hemophilia? A. 0 percent B. 25 percent C. 50 percent D. 100 percent

Answers

Answer 1
Answer: Without a pedigree chart, it is not possible to answer this question. However, given this is a HS bio class question, they are probably looking for the simplistic answer "A", zero percent, based on the erroneous notion that women cannot have hemophilia. Women carriers of a defective gene coding for hemophilia frequently do themselves have mild or moderate hemophilia and, in very rare cases, severe hemophilia.

  1. Most of the edges or the boundaries of the continents perfectly matches with the nearby continents.
  2. Similar fossil assemblages has been found in different continents.
  3. Similar rocks have been found at different continents, and also similar age has been observed.
  4. Plate tectonic theory confirmed that all continents earlier were together.
Similar types of rocks in places, same species of animals with slight different evolutions to adapt to climate, the landmasses actually look like they fit together, etc..

About 3 million Brazilian free-tailed bats live near Fredericksburg, Texas, in an abandoned railroad tunnel. Eighty percent of the free-tail's diet includes agricultural pests such as the cutworm, corn borer, and webworm moths. Each can eat its weight in insects nightly, and the whole colony may devour over 25 tons of moths per night. The bats return to the tunnel between midnight and daybreak, having traveled an average 25 to 30 miles to forage. As the population of bats increases, it is expected that the crop production in nearby areas will —

Answers

As the population of bats increases, it is expected that the crop production in nearby areas will decreases.

How the population of bats can be affected?

The population of bats which can be affected by the numerous factors as to will its population increase or decrease, just as at any other organism. If the populations of their food source decrease, the bats will have less food, thus their numbers will decrease.

The same which shows deadly diseases spreads among them, as many will be infected and will die out. They also have predators, so if some of their predators has increase in its population, the population of bats will go down.

Therefore, As the population of bats increases, it is expected that the crop production in nearby areas will decreases.

The increase in the population of free-tailed bats near Fredericksburg, Texas is expected to increase crop production in nearby areas.

As the population of free-tailed bats near Fredericksburg, Texas increases, it is expected that the crop production in nearby areas will increase. This is because the bats primarily feed on agricultural pests such as cutworms, corn borers, and webworm moths, which can damage crops. As the bats consume a large number of these pests, they help control their population and reduce crop damage.
