Phenylalanine is required for the production of many bodily proteins, but none of your cells are capable of synthesizing this essential amino acid. What type of metabolic pathway must be responsible for providing phenylalanine to your cells? How would your diet effect the mount of Phenylalanine that is available?
Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.

Identify a food chain that consists of a producer, a primary consumer, a secondary consumer and a tertiary consumer.
Answer:
A producer consumes water and sunlight, while a primary eats the producers, while the secondary can either eat the producers and the primary consumers or just eats the primary consumers. The tertiary consumers are at the top of the food chain and can eat all of the above for a stable food source.
A patient suffering from breast cancer chooses to undergo surgery. Doctors remove the breast where the tumor is. However, doctors say that there is no guarantee the cancer will not come back. What makes it so hard to cure cancer? Check all that apply. A single diseased cell can multiply into a new tumor. Cancer cells can travel through the blood and spread into new areas. There is no research being done on possible cures. Many cancer cells multiply so fast that new tumors can form.
Answer:
The correct answers are: A single diseased cell can multiply into a new tumor; cancer cells can travel through the blood and spread into new areas; many cancer cells multiply so fast that new tumors can form.
Explanation:
Cancer is the term that groups different conditions that have all one thing in common: there's an abnormal cell growth that can potentially irradiate to other parts of the body.
A single diseased cell can develop a tumor, because this abnormal cell has the capacity to replicate so fast and, of course, transmit its abnormality to every other cell that it generates.
These abnormalities occur because there is some sort of damage in the DNA of a cell, which most of the time is detected by the body and eliminated - but when it's not, the cell quickly multiplies itself and generates a tumor. The difference between a benign tumor and cancer is that cancer can spread through the body and a benign tumor can not.
Cancer is very dangerous and potentially fatal if not treated fast because it can travel through the bloodstream or the lymphatic system and invade other organs, causing metastasis.
There's a lot of research being done on how to cure cancer, but the disparities in every different type of cancer make finding the solution much harder. Nowadays, depending on the type of cancer and the stage where the cancer is, this condition can be treated with radiotherapy, chemotherapy, or surgery.
Answer:
A, B, D

Which best explains why the sun maintains its size and shape?
A. Pressure caused by high temperatures are balanced by gravity.
B. The sun burns from its core to its surface.
о
C. Forces exerted by orbiting planets cause the sun to rotate.
Answer:
A
Explanation:
The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.
The best explanation of why the sun maintains its size and shape is forces exerted by orbiting planets cause the sun to rotate. The correct option is C.
What is orbiting?"Orbiting" is one of those digital dating terms that perfectly describes what many of us have experienced but didn't realize had a name. It's when someone you were dating tells you they're no longer interested but keeps in touch with you on social media.
The Sun's own weight holds it together and maintains its size and shape. Everything has gravity. In this example, the sun maintains its shape by balancing gravity and pressure.
Planets orbit the sun in elliptical orbits, with the sun slightly off-center of each ellipse.
Therefore, the correct option is C. Forces exerted by orbiting planets cause the sun to rotate.

Why are sex-linked traits more common in males than in females?
a.All alleles on the X chromosome are dominant.
b.All alleles on the Y chromosome are recessive.
c.A recessive allele on the X chromosome will always produce the trait in a male.
d.Any allele on the Y chromosome will be codominant with the matching allele on the X chromosome
Answer:A
Explanation:
Sex-linked traits are more common in males than in females because all alleles on the X chromosome are dominant.
What do you mean by sex-linked traits?Sex linked describes the sex-specific patterns of inheritance and presentation when a gene mutation is present on a sex chromosome rather than a non-sex chromosome. In humans, these are termed X-linked recessive, X-linked dominant and Y-linked.
And in humans this is the X or the Y chromosomes. And so some of the more familiar sex-linked traits are hemophilia, red-green color blindness, congenital night blindness.
Sex-linked traits are characteristics that are determined by genes located on the sex chromosomes. Inheritance patterns for these traits can differ for males and females, since the X and Y chromosomes differ.

what is the pH of a solution with a H+ ion concentration of 1 x 10^-4
Answer:
A logarithmic scale condenses the range of acidity to numbers that are easy to use. Consider a solution with [H + ] = 1.0 × 10 -4 M. That is a hydrogen-ion concentration that is 1000 times higher than the concentration in pure water. The pH of such a solution is 4.00, a difference of just 3 pH units.
Which best describes a difference between transcription and DNA
replication?
A. Only transcription happens in the nucleus.
B. Transcription does not require DNA.
C. DNA replication uses thymine.
D. DNA replication takes place in the ribosome.
Answer:
DNA replication is the process of making new copies of DNA. Transcription is the process by which DNA is copied (transcribed) to RNA.
Explanation:
The best option that describes a difference between transcription and DNA replication is B: Transcription does not require DNA.
What is DNA transcription?Transcription is the process in which genetic information in DNA is used to produce RNA molecules, which can then be used to synthesize proteins. In this process, a segment of DNA is first transcribed into messenger RNA (mRNA) by RNA polymerase enzymes, which does not require the DNA template to be replicated.
On the other hand, DNA replication is the process in which a cell makes an identical copy of its DNA, which occurs prior to cell division. This process involves the copying of the entire DNA strand, including the use of DNA as the template to form new strands, and is carried out by specialized enzymes.
Therefore, while both transcription and DNA replication involve the copying of genetic information, they differ in their mechanisms and requirements.
