Why DMD mostly affects boys?

Answers

Answer 1
DMD affects boys because the dystrophin gene is on the X chromosome. Chromosomes are the parts of your cells that contain your genes. Boys only have one X chromosome. Girls have two X chromosomes, one from each parent.

Answer 2

Answer: The DMD gene is located on the X chromosome, so Duchenne muscular dystrophy is an X-linked disease and mostly affects males because they have only one copy of the X-chromosome

Why might larger jaws and teeth become more common in jaguar species over time? In your response use the 4 principles of natural selection to support your answer. (Genetic variation, overpopulation, competition, and adaption) Please help it's due today

Answers

Answer:

Larger jaws and teeth may become more common in jaguar species over a period of time for a few reasons. To start off with, the genetic pool needs to prompt the species to have multiple offspring of different genealogy lines (non-inbred). Those offspring with the new attributes would have to adapt and survive. They wouldn't necessarily need to do better than the normal variation of jaguar, they just need to do well enough to mate. In terms of mating, the offspring with the mutation would have to mate with each other since the mutation would most likely be recessive. Over time, with more offspring that contain the mutation and keep breeding together, the recessive gene would become dominant (I think that's how that works) within the population. Once the population is high enough, there would be a competition between the normal variation and new variation of jaguars.  Assuming the new variation out-competes the normal variation, natural selection had occurred and you have a result.  I hope this helps!

Once a fossil has been formed, it still might not become part of the fossil record. Describe two natural processes that might destroy the fossil.​

Answers

Once buried, the fossil and surrounding rock might undergo extreme pressure and heat, and the fossils could melt. Once fossils are formed, they might be washed away by streams, moved by glaciers, carried by scavengers, or caught in rockslides. Weathering by wind, water, and sun can destroy a fossil by wearing it away.

Answer:

the first one is by melting because of the extreme pressure and heat and the other way is being washed away or something

QUESTION: How is soil important to living organisms? (Like Humans, animals, plants)

Answers

Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. ... Soil plays a vital role in the Earth's ecosystem. Without soil human life would be very difficult.

Answer:

​There are seven general roles that soils play:

1 Soils serve as media for growth of all kinds of plants.

2 Soils modify the atmosphere by emitting and absorbing gases (carbon dioxide, methane, water vapor, and the like) and dust.

3 Soils provide habitat for animals that live in the soil (such as groundhogs and mice) to organisms (such as bacteria and fungi), that account for most of the living things on Earth.

4 Soils absorb, hold, release, alter, and purify most of the water in terrestrial systems.

5 Soils process recycled nutrients, including carbon, so that living things can use them over and over again.

6 Soils serve as engineering media for construction of foundations, roadbeds, dams and buildings, and preserve or destroy artifacts of human endeavors.

7 Soils act as a living filter to clean water before it moves into an aquifer.
