. It's very rare for someone with two X chromosomes to have DMD. Explain how a person with two X chromosomes could have the symptoms of DMD using what you know about inheritance and random mutation.
Answers
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.

What is tectonic plates?
Earth’s tectonic plates are part of the planet’s crust which correctly describes Earth’s tectonic plates. Huge fragments of the upper mantle and crust make form tectonic plates. Both continental and oceanic crust make up their composition. Mid-ocean ridges and the significant faults that delineate the plate boundaries are subject to earthquake activity.
Our globe would look drastically different if it weren't for plate tectonics. We have a stable climate, mineral and oil deposits, and oceans with a chemical balance that supports life thanks to the continuous recycling of the Earth's crust.
The tectonic plates, which have a thickness of about 100 km, are made up of this crustal layer of the globe. These plates, which continue to float on the warm and thick mantle, collided to create the mountains.
Therefore, The arrows on either side of the fault represent the relative movement of the two tectonic plates. The type of boundary is represented in the diagram is convergent. Thus, option B is correct.

Svetlana learned that there are organisms that live deep in the ocean that produce food using energy stored in chemicals.
What process do these organisms most likely use to produce food?
Answers
Answer:
chemosynthesis
Explanation:
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
There are two various ways by which organisms produce food. This is through photosynthesis which is utilized by plants and chemosynthesis which is utilized by some other organisms.
The process by which organisms that live deep in the ocean produce food using energy stored in chemicals is through chemosynthesis.
Organisms that live deep in the ocean are unable to access sunlight to enable them produce their food so they use the process of chemosynthesis.Chemosynthesis is utilized by some bacteria. They do this by using chemicals in the place of sunlight unlike photosynthesis as a source of energy to produce food (glucose). It involves the conversion of one or more carbon-containing molecules (e.g methane) into organic matter using the oxidation of inorganic chemicals.Learn more: https://brainly.com/question/15115717

D. Humans drink springwater
Answers
Answer: A
Explanation:
Precipitation is absorbed into the ground represents an interaction between the biosphere and the atmosphere. Thus, the correct option is A.
What is the interaction between biosphere and the atmosphere?
The interaction between biosphere and the hydrosphere, includes the biosphere which requires water to drink for animals and for the growth of plants which are present in the biosphere. Water is provided by the hydrosphere through precipitation. This interaction between the hydrosphere and biosphere helps the life on Earth to be more sustainable.
Plants draw water and different nutrients from the soil and release water vapor into the atmosphere. This is possible by the precipitation which results into the absorption of water and minerals into the ground.
Therefore, the correct option is A.

A cell membrane is more flexible than a brick wall. Why might many cells benefit from a flexible cell membrane? and A building has different types of openings, such as windows and doors. Do you think a cell also has different types of openings? Give an explanation for your answer. I NEED HELP NOW I HAVE TO SUBMIT
Answers
Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
A cell membrane's flexibility aids in the selective passage of substances across it. Endocytosis, a mechanism that enables amoeba to take in food particles from the environment, is made possible by the flexibility of the membrane.
What make cell membrane to be flexible?The majority of natural phospholipids' fatty acids include one or more double bonds, which cause the hydrocarbon chains to twist and are challenging to pack together.
The interior of the membrane can displace freely due to the prolonged hydrocarbon chains of the fatty acids, getting the membrane itself negotiable and supple.
Key fatty acids include arachidonic and docosahexaenoic acids. Due to its four double bonds, arachidonic acid's proportion in phospholipid tails can be slightly increased to improve membrane flexibility.
Therefore, cell flexibility is important for cell to function.

Explanation:
The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life. As a result, many organisms that require light for photosynthesis can live in this zone, including seaweeds and phytoplankton. Most coral reefs are also found in the neritic zone. ...

Sydney and Valparaiso are the same distance from the equator and both are near the ocean. Is Valparaiso warmer, colder, or the same temperature as Sydney?
Answers
Answer:
They are the same in temperature both of Valparaiso and Sydney because they have equal distance from the equator and the same geographical location which gives sense that they are similar in weather patterns and climate but depends on phenomenal events.
Explanation:
The Equator is the imaginary middle latitude, which divides the Earth into Northern and Southern hemispheres.
Sydney and Valaparasio are equidistant from the equator and have the same climatic conditions.
Sydney is located 2,340 miles away from the equator. The city is located near the ocean and enjoys a sunny climate with warm summers and little winters. The average temperature ranges between 18.6-degree to 25.8-degree Celcius.
Valparaiso is situated 2,284 miles away from the equator and near the ocean. The city enjoys mild winters, humidity, and comfortable summers. The average temperature of the city ranges between 14-degrees to 30-degrees.
