Answer: Duchenne muscular dystrophy (DMD) is inherited through X-linked recessive inheritance mode. It is characterized by muscle weakness which mostly affect boys. It can only affect girls when a female carrier got married to affected male.
Explanation: In the union between a carrier female and an affected male, four types of gametes will be produced as shown in the attached image. After fertilization, the resulting offsprings will consist of female carrier, normal male, female affected and male affected each with 25% probability. See attached image for better illustration.
X-linked recessive traits have the following characteristics;
1. More males are affected than females.
2. Approximately ½ of a carrier mother's sons are affected.
3. It is never passed from father to son.
4. All daughters of affected fathers are carrier.

A study shows that a new pesticide is safe for use on food crops. The researcher who conducted
the study works for the pesticide company. What potential biases may have affected the study?
Answers
Answer:
Funding Bias
Explanation:
Funding Bias or Funding Outcome Bias refers to the tendancy of a scientific study or research to support the interests of the study's financial sponsor.
The potential that biases may have affected the study is the researcher most likely left out other data that might have supported that the pesticide wasn't safe on food crops.
What are pesticides?Pesticides are chemicals that are used in crops to remove or kill insects that feed on crops or impact the crops. These pesticides are made up of harmful chemicals, so they also impact the crops and the organism that eat the crops.
Here, the study is showing the adverse effect of pesticides, which could show by the proven effect on organisms in the experiment.
Thus, the researcher most certainly omitted further data that could have provided evidence that the pesticide wasn't safe for use on food crops, raising the possibility that biases may have skewed the study.

This macromolecule forms pumps and channels within the cell membrane. They act like to let molecules in and out of the cell.
- Carbohydrates
- Lipids
- Nucleic acids
- Proteins
Answers
Answer:
The macromolecules that forms pumps and channels in the cell membrane, allowing the entry and exit of molecules to the cell are protein.
Explanation:
Membrane integral proteins are a type of macromolecule attached to the structure of the membrane and have ends in contact with the cytoplasm and the extracellular medium.
These protein molecules can act as channels and transporters or pumps, to facilitate the passage of substances through the membrane. An example of transmembrane channels are ion channels, while a protein transporter is the sodium potassium ATP-ase pump.
Membrane proteins can also act as surface receptors and enzymes linked to the cell membrane.
The other options are not correct because :
Carbohydrates can be found on the membrane bound to other molecules, such as glycoproteins and glycolipids, but they do not act as pumps or channels. Lipids have the function of being the main component of the cell membranes. Nucleic acids are found in the nucleus, and are not part of the cell membrane.need help fast pleassssssssssssseeeeeeeeeeeee i am timeeeeeeeeeddddddddd Biodiesel fuel can be created from __________, an important resource in South and Southeast Asia.

How is it that every living organism has specialized cells that contain genetic material made up of only four different bases, yet every organism is different?
Answers
Answer:
See the answer below
Explanation:
The answer lies mainly in the genetic codes which are translated differently in different organisms.
The genetic code degenerates such that 64 possible codons from the four bases ([tex]4^3[/tex]) codes for the 20 amino acids that are available in nature. The transfer RNA is primarily responsible for the translation of the genetic codes and different organisms have different transfer RNA. Hence, the same genetic codes are differently translated in different organisms and this ensures that organisms are different.

What happens in Gilded age?The American Gilded Age was a period of immense economic change, great conflict between the old ways and brand new systems, and huge fortunes were made and lost.
The Gilded Age was a period of economic growth as the United States jumped to the lead in industrialization ahead of Britain. The nation was rapidly expanding its economy into new areas, especially heavy industry like factories, railroads, and coal mining.
As daunting as the political challenges were at the time, the Gilded Age came to an end with the reforms of the Progressive era and the New Deal. Those years saw countless changes in the rules of economic life as well as new taxes and social spending.

which area of the North American continent would have the greatest risk of earthquake damage?
Answers
Answer:
The area is California.
Explanation:
There are 500,000 seismic tremors occurring out of which most of them are in the California zone. Over 80% of seismic tremors happen in a territory known as the Pacific Ring of Fire, a 25,000-mile horseshoe shape along the north side of the Pacific Ocean.
The principle purpose behind the distinction is that the California coast is directly over the limit of two of the structural plates that make up the Earth's covering.
Earth's covering, the lithosphere, is separated into in excess of twelve strong plates that buoy over a progressively gooey layer of hot shake.
In California, plates are granulating against one another. Envision striking two blocks against each other, often as possible reason them to split, perhaps severing lumps. As increasingly more weight is included, the block is probably going to break someplace in the center.
