Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fibrosis and isn't a carrier. Use F to denote the normal allele and f to denote the mutated CFR allele. What percentage of their children are likely to have cystic fibrosis? What percentage of their children are likely to be carriers of cystic fibrosis?
Answer:
50% of their children are likely to be carriers of cystic fibrosis
Explanation:
Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF". The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.

What are some processes that take CO2 out of the atmosphere.
Photosynthesis photosynthesis takes carbon from the atmosphere but do not get it mixed up with respiration which takes O2 out the atmosphere and replaces it with Co2
Photosynthesis takes carbon from the atmosphere but do not get it mixed up with respiration which takes O2 out the atmosphere and replaces it with Co2.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

is chlorine gas a polar or nonpolar covalent bond
Pretty sure its non-poaler (definitly sure) :)
Answer:
Explanation:
Covalent bonds are very similar to chlorine gas. Which is also known as (C12). Both of these atoms share and hold tightly onto their electrons.
The hydrogen atom has a positive charge becauseIt cannot hold as tightly to the negative electron bones. Covalent molecules with this type of uneven charge distribution are polar.

Roads are onen bum through forests for industrial purposes or as land is developed for residential and commercial needs. How would road construction
through a forest most likely affect the ecosystem?
Non-native species would replace native species
The number of primary consumers would increase
The natural succession of vegetation would change
All producers would be eliminated from the community
Answer:
The natural succession of vegetation would change
Explanation:
Originally, a forest is an area rich in biodiversity of species. It consists of different populations, and communities. According to this question, if a road is built through a forest for industrial purposes, this will negatively affect the biodiversity of such forest.
One notable occurrence that would result from this is the CHANGE IN THE NATURAL SUCCESSION OF THE VEGETATION. This change is the destruction of the ecosystem that occurs due to industrialization (road construction).

Earth's physical layers-
Earth's compositional layers-
: : includes lithosphere
: : includes crust
: : based on density of each layer
: : based on chemical makeup of each layer
Answer:
Earth's physical layers: includes lithosphere, based on density of each layer
Earth's Compositional Layers: includes crust, based on chemical makeup of each layer
Explanation:
Earth's physical layers - lithosphere, based on density of each layer
Earth's Compositional Layers - crust, based on chemical makeup of each layer.
The physical layers of the Earth include the asthenosphere and lithosphere. The asthenosphere is the zone of Earth's mantle that lies below the lithosphere. On the other hand, the lithosphere simply means the rocky outer part of the Earth.
The compositional layers of the Earth include the mantle, the crust, the outer core, and the inner core. The crust is the outermost part of the Earth. It is the top component of the lithosphere.

How do scientists explain the slow rotation of the sun with respect to the rest of the solar system?
Answer:
The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.
Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun's equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this "differential rotation" is an area of current research in solar astronomy.

A characteristic common to eukaryotic cells that is not found in prokaryotic cells is the
cell membrane
presence of DNA
use of ribosomes for protein synthesis
presence of mitochondria
Answer:
Presence of the Mitochondrion!!
Explanation:
~
A characteristic common to eukaryotic cells that are not found in prokaryotic cells is the presence of mitochondria. Thus, the correct option for this question is D.
What is a Prokaryotic cell?A prokaryotic cell may be defined as a type of cell which is present in prokaryotes. This type of cell typically lacks a well-defined nucleus and other membrane-bound cell organelles. Organisms like bacteria, archaea, etc. possess this type of cell.
All prokaryotes and eukaryotes have a cell membrane known as a Plasma membrane. Most prokaryotic organisms have a small amount of genetic material in the form of a single molecule known as circular DNA.
Protein synthesis is one of the essential functions of all cell types. Ribosomes are significantly found in every type of eukaryotic as well as prokaryotic organisms like bacteria.
Therefore, the presence of mitochondria is a characteristic that is only common to eukaryotic cells but is not found in prokaryotic cells.

Colorectal surgeon requires the most years of education prior to working.
What is the most common complication of colorectal surgery?The most common complications following colorectal resection are infectious, wound infection or organ space infection, and gastrointestinal (GI) motility complications, including ileus and bowel obstruction.
Colon and rectal surgeries are typically performed to treat colon and rectal cancers, inflammatory bowel disease (IBD), or diverticulitis, and may also be necessary following an injury or wound, serious infection, or bowel blockage.
Colorectal surgery is a major surgical procedure. Prior to surgery, you will undergo a number of tests and scans, and your medications may change. You will also need to prepare your bowels by taking laxatives to clear your intestines before surgery.
