Joe, age 14, recently fractured his forearm midway between his wrist & elbow. Should his physician be concerned about his epiphyseal plate being affected and causing bone growth to stop?
Joe's doctor must be concerned that his bone growth will be hampered by damage to the epiphyseal plate.
We can arrive at this answer because:
The epiphyseal plate is a set of cartilage present at the end of long bones, such as the bones present in the forearm.The epiphyseal plate is responsible for the longitudinal and lateral growth of the bone.This growth occurs during childhood and adolescence, for this reason, it is essential to maintain the good integrity of this plaque during this time of life.In the case of Joa, who is still a teenager, a fractured forearm can damage his epiphyseal plate and affect his body's bone growth, so his doctor should be concerned about this.
It is important to note that during adult life, the epiphyseal plate is replaced by an epiphyseal line.

Which of the following is a disadvantage of genetic engineering?
May cause negative side effects
Cannot create new organisms
Reduces the nutrition value of food
Increases the scarcity of food in the world
Answer:
may cause negative side effects
Explanation:
Answer:
May cause negative side effects.
Explanation:
I took the test
Genetic Engineering is used to put genes from one organisms into another. The new organism can reproduce. And while it may seem like it's the answer the nutrition value and scarcity of food is in no way impacted. It's not like cloning. Where more are being created in large amounts with similar diets. They can be cross-pollinated with organisms with different diets. So the only obvious answer would be the negative side effects.

what is the function of the filaments found in ranges 1-2 and 6-7 but no other ranges?
Answer:
What is the function of the filaments found in ranges 1-2 and 6-7 but no other ranges? Elastic (titin) filaments help to protect the muscle from overstretching and also aid in returning it to normal length. This enzyme breaks down acetylcholine into acetic acid and choline.

a typical human chromosome contains about how many nucleotides in its dna?
Answer:
50 million nucleotide pairs
The typical human chromosome contains 50 million nucleotide pairs
in its DNA.
What is DNA?Deoxyribonucleic acid (DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macro molecules that are essential for all known forms of life.
Hence, The typical human chromosome contains 50 million nucleotide pairs.

corn to cattle instead?
Explanation:
Since corn was very cheap, the farmers raised cattle on corn also believing that the cows would gain more weight, therefore, more product or supply for them to sell. However, this resulted in the cows begin developing a disease called E. Coli, which then leads to social issues.
Answer:
the cattle are more on a risk of health diseases
Explanation:
because corn has nutrients but not enough of each to provide the cattle the nutrients it needs
Which of the following does not describe a source of greenhouse gases?
Steam of fossil fuels
Burning of fossil fuels
Freezing of permafrost
Emissions from landfills
Answer:
i think its C) Freezing of perma frost
Explanation:
The option that does not describe a source of greenhouse gases is the freezing of glaciers. Thus, the correct option is C.
What are greenhouse gases?Greenhouse gases may be defined as those gases that are present in the earth's atmosphere and trap the heat and radiation from the sun and emitted toward the earth.
Such greenhouse gases are responsible for the greenhouse effect that ultimately leads to global warming.
Steaming and burning of fossil fuels and emissions from landfills extremely liberated the high amount of carbon dioxide in the atmosphere which is one of the most potent greenhouse gas.
Therefore, the option that does not describe a source of greenhouse gases is the freezing of glaciers (hailstone). Thus, the correct option is C.

When referring to cell division, oncogenes are most like ________ while tumor suppressor genes are most like ________. the brakes on a car; the gas pedal on a car the steering wheel on a car; the gas pedal on a car the gas pedal on a car; the brakes on a car the brakes on a car; the steering wheel on a car
Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.
From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.2. Process B: Facilitated diffusion.
Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.3. Process C: Active transport.
Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.Read more: https://brainly.com/question/18646362
