The most common form of hemophilia is a defect in blood clotting factor VIII, which is caused by a mutant form of a gene on the X chromosome. Boys who inherit that mutation from their mother suffer from uncontrolled bleeding. Girls carrying one copy of this mutation have near normal blood clotting. Uncommonly, a girl is born with hemophilia even though both parents have normal phenotypes. Which of the statements might explain hemophilia in a girl born to parents with normal blood clotting phenotypes?

Answers

Answer 1

Answer:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.

Explanation:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.  

It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.

However, such mutant (X) communicates and expresses itself and she is hemophilic.

This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.

An immunodeficiency condition called bare lymphocyte syndrome is caused by a genetic defect that results in an inability to synthesize MHC class II molecules.

a. True
b. False

Answers

Answer:

True

Explanation:

This is because lymphocyte syndrome is a genetic condition where there is absence of or in ability of the cell to express histocompatibility complex class II or MHC class II and this lead to incapability of the immune system to fight infections. The immune system is compromised and weakened to fight infections.

Which is NOT a benefit of xenophyophores in a habitat?
1 They maintain benthic biodiversity.
2 They increase populations of isopods, mollusks, and crustaceans.
3 They churn up sediments that build up on the ocean floor.
4 They convert salt and iron into energy and nutrients.

Answers

The correct answer is 4. They convert salt and iron into energy and nutrients.

Explanation

Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

Answers

Explanation:

Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.

Below are some of the regional impacts of global change forecast by the Intergovernmental Panel on Climate Change:

North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.

Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.

Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.

Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.

Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions

Which of the following factors decrease biodiversity? (Choose all that apply)
a. habitat destruction
b. unpredictable precipitation
c. warm temperatures
d. freezing temperatures

Answers

Answer:

habitat destruction, unpredictable precipitation, and freeing temperatures.

Explanation:

i took the quiz

The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.

What is biodiversity?

Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.

The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.

The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.

Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.

 

Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.

C. By changing the genetic material inside your cells
D. By breaking down your cells for nutrients

Answers

Answer:

A. By releasing toxins that poison your cells

B. By using your cells to make copies of themselves

Explanation:

Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery.  For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.
