A young man recently learned from a genetics doctor that he had a condition called Friedreich's ataxia. This syndrome affects the arms and the legs with the person usually needing a wheel chair. Neither of his parents have this disorder. However the young man's grandfather was wheelchair bound, but didn't know why because genetic information was very limited when his grandfather grew up.

How was early Earth's atmosphere different from today's atmosphere?
Answer:
The early Earth was very different from our Earth today.
Explanation:
Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.
Answer:
The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.
How has the Earth's atmosphere changed over time?
Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

The cell cycle begins again after
A. synthesis has copied each chromosome.
B. mitosis has formed two identical nuclei.
C. cytokinesis has formed two new cells.
D. differentiation has made cells specialized.
Answer:
C. cytokinesis has formed two new cells.
Explanation:
Cell cycle has different stages called G1, S, G2, and M. ... This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.

Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.

Which of the following explains why an apple looks red? The apple reflects red light and absorbs all other visible wavelengths. The apple absorbs red light, and reflects all other colors of light.. The apple is absorbs all visible wavelengths, but absorbs red light better The apple is reflects all light that hits its surface.
Answer:
The apple reflects red light and absorbs all other visible wavelengths
Explanation:
The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)
The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.
What is Absorption and reflection of light?Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.
Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.
Therefore, the correct option is A.

Students were investigating the movement of water through a semi-pern
with the salt concentration shown below.
Answer:
It depends on the salt concentration inside the cell.
Explanation:
The movement of water through a semi-permeable membrane with different salt concentrations depends on the amount of water and salt concentration in the cell. If the cell has more salt concentration so no more salt moves inside the cell but moves outside the cell while on the other hand, if the cell has low amount of salt than the outer environment then the salt moves inside the cell until its concentration are equal.

Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?
Answer:
Ecosystem follows the 10% law.
Explanation:
The amount of energy that is available in the ecosystem is equal and same is equally distributed. Plants use solar energy and convert it into usable energy for processing food and water in tissues and reproduction and root development. Later on when the plant dies or is eaten up the dead organic matter is converted to energy that is derived by the herbivorous or primary consumer. When then (90%) lost through respiration and digestion, waste generation in the body. After which the energy left may be again taken up by some secondary consumer and only 10% energy remains while the rest is diffused in the ecosystem and environment. Thus energy is neither created nor destroyed but transformed in its form.Please needed as soon as possible thank you!

What evidence is there that all living things are made of cells?
A cell can be described as the structural and functional unit of life. It can also be described as the building material of all living organisms.
Without the cell, most living organisms will not be able to function. An organelle will not be able to survive that long within its life span without the presence of cells. It will just withe and die off.
Lots of scientists have proved in various ways the existence of cells, this is because they have been able to create microscopes that can see these tiny cells. This is evidence that proves the existence of cells.

Answer:
Then, what is the question????
In 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.
What is Microscope?A microscope is defined as a laboratory instrument used to examine objects that are too small to be seen by the uncovered eye. Microscopy is the science of examining small objects and structures using a microscope. The word microscopic means invisible to the eye unless aided by a microscope.
Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.

A black hybrid rabbit is crossed with a white purebred rabbit.
What is the probability of an offspring being black?
A. 25%
B. 50%
C. 75%
Answer
A. 25%
Explanation:
This is because the black hybrid would be 50% one breed and 50% another breed. Then the white purebred is 100% one specific breed. So by mating, all of those breeds that the parents have all reduce by 1/2 for the offspring.
