Need help ASSP Make an inference: If the aliens had similar enzymes to mammals on Earth, how do you think changing the pH (either very acidic or basic) would affect the aliens? Explain your reasoning.
Answers
Based on what we know, we can confirm that a very acidic or basic change to the pH would most likely cause death to aliens that have similar enzymes to the mammals on Earth.
Why would this change cause the Aliens to die off?This has to do with the role of enzymes in the body. Enzymes are catalysts for just about all of the reactions that take place in the bodies of mammals. These enzymes that are essential for life, are very vulnerable to strong changes in pH, which cause them to denature and lose functionality.
Therefore, we can confirm that a very acidic or basic change to the pH would most likely cause death to aliens that have similar enzymes to the mammals on Earth.

Assortative mating, in human genetics, a form of nonrandom mating in which pair bonds are established on the basis of phenotype (observable characteristics).
What is Assortative mating?A person may choose a mate according to religious, cultural, or ethnic preferences, professional interests, or physical traits.
Positive assortative mating, or homogamy, exists when people choose to mate with persons similar to themselves (e.g., when a tall person mates with a tall person); this type of selection is very common.
Negative assortative mating is the opposite case, when people avoid mating with persons similar to themselves. Assortative mating also occurs in nonhuman animal populations. Indeed, phenotypic similarity is thought to underlie mate selection in a variety of species.

difference between elodea cells and onion cellsElodea cells and the plant itself serve as producers in natural settings because they are photosynthetic plants. Plants use light energy to transform carbon dioxide and water into sugars and oxygen through a process known as photosynthesis. It is the primary pathway for energy to enter an ecosystem.
Elodea cells photosynthesize because they develop in sunlight and are frequently categorized as waterweeds.
Onions cells, on the other hand, grow below the surface, therefore their cells cannot photosynthesize. Additionally, elodea cells have a vacuole that is filled with cell sap, a fluid that is mostly composed of water.

This contributes to suffer from different diseases, which can become chronic if the condition gets unattended.
1. Conditions happen to be really good this year for breeding and next year there are 1,245 young

3. The ability to taste PTC is due to a single dominate allele "T". You sampled 215 individuals in biology, and
determined that 150 could detect the bitter taste of PTC and 65 could not. Calculate allelic and genotypic
frequencies for this population..
Answers
On the conditions being really good this year for breeding:
153 young "potential" Biology instructors to have poor vision and 525 to have good vision. 15% of the mice will be homozygous dominant (AA), 47% will be heterozygous (Aa), and 38% will be homozygous recessive (aa).49% of the individuals will be homozygous dominant (TT), 39% will be heterozygous (Tt), and 12% will be homozygous recessive (tt).How to calculate frequencies?1. The Hardy-Weinberg principle states that in a population in which mating is random, the frequency of alleles will remain constant from generation to generation. This means that if the frequency of the allele for poor vision is p and the frequency of the allele for good vision is q, then the frequency of each genotype will be:
AA = p²
Aa = 2pq
aa = q²
In this case, the frequency of poor vision is 0.35, so p = 0.35 and q = 0.65. This means that the frequency of each genotype will be:
AA = (0.35)² = 0.1225
Aa = 2(0.35)(0.65) = 0.4225
aa = (0.65)² = 0.4225
Therefore, we would expect 1,245 × 0.1225 = 153 young "potential" Biology instructors to have poor vision and 1,245 × 0.4225 = 525 to have good vision.
2. The allele for white coloring is recessive, so the only way for a mouse to be white is if it inherits two copies of the recessive allele. If the frequency of the white allele is q, then the frequency of white mice will be q². In this case, 35% of the mice are white, so q = 0.588. This means that the frequency of the white allele is 0.588 and the frequency of the non-white allele is 0.412.
The genotypic frequencies can be calculated using the Hardy-Weinberg principle:
AA = p² = (0.412)² = 0.169
Aa = 2pq = 2(0.412)(0.588) = 0.472
aa = q² = (0.588)² = 0.338
Therefore, 15% of the mice will be homozygous dominant (AA), 47% will be heterozygous (Aa), and 38% will be homozygous recessive (aa).
3. The ability to taste PTC is due to a single dominant allele "T". If the frequency of the T allele is p, then the frequency of the t allele is q = 1 - p. In this case, 150 of the 215 individuals could detect the bitter taste of PTC, which means that p = 0.702. This means that the frequency of the T allele is 0.702 and the frequency of the t allele is 0.298.
The genotypic frequencies can be calculated using the Hardy-Weinberg principle:
TT = p² = (0.702)² = 0.492
Tt = 2pq = 2(0.702)(0.298) = 0.392
tt = q² = (0.298)² = 0.088
Therefore, 49% of the individuals will be homozygous dominant (TT), 39% will be heterozygous (Tt), and 12% will be homozygous recessive (tt).

The molecules that are secreted by the nervous system are ligands (neurotransmitters), and they fit on the receptors present on the cell surface with which they are associated.
What is the ligand-receptor association?The neuron that is connected to the next neuron secretes some neurotransmitters at the axon end, and those fit the next neuron's receptors that are present on the cell surface. After the ligand-receptor interaction, the rest of the signaling starts in the neuron. Some of the neurotransmitters are excitatory in nature and activate the function, while others are inhibitory in nature and inhibit the function after attaching to the receptors.
Neurons are associated with muscles and glands, and they secrete the ligands that are neurotransmitters, and the receptors present on them work accordingly. In this way, the neurons regulate the body's functions.
Hence, the nervous system releases ligands (neurotransmitters) that fit into the receptors on the cell surface.

Answer:
Explanation:
a.
The individual should be diagnosed for hypertension or high blood pressure.
b.
It is recommended that the patient should take low sodium diet because when sodium or salt enters the blood stream it increases the amount of water or fluids in the blood stream that leads to rise in blood pressure. The blood pressure increases if we take high salt diet due to which arterioles constrict.
c.
Diuretics- Diuretics are the first recommended therapy in treating hypertension. Diuretics such as thizides , pottasium sparing agents. Thiazide acts on distal convoluted tubule that inhibits Na+ and Cl - symporter. Diutetic removes water from body as urine and loss of salt.
Beta blockers - These are antagonists. They block the beta receptors found on the target cell membrane. Beta blockers slows down blood pressure. Atenolol is the beta blocker used for hypertension.
Alpha1 blocker - alpha 1 receptors helps in smooth muscle contraction and vasoconstriction. Vasodilator increases blood flow in the body that are devoid of oxygen that helps to reduce blood pressure.
angiotensin converting enzyme inhibitor - blocks angiotensin converting enzyme that prevents converting angiotensin I to angiotensin II and increases bradykinin levels in the body. These inhibitors helps in lowering blood pressure.

For this discussion post, I read the article “A creator of ‘CRISPR babies’ nears release from prison, where does embryo editing stand?
This article explained how biophysicist He Jiankui, who used the genome editor CRISPR to create the world's first genetically engineered babies, may be released from prison this week.
His November 2018 announcement about gene editing was well received. Still, Fyodor Urnov sees no circumstance that would justify efforts to modify babies genetically. Urnov supports using CRISPR to fix disease-causing mutations after birth. The work has proceeded with little notice, and oversight measures to stop rogue experiments like He's have stalled. A study showed how CRISPR could get rid of a newly fertilized egg of an extra copy of a chromosome. This problem can lead to Down syndrome and other medical conditions. The initial concerns about designer babies centered on CRISPR's sloppiness. But a study of CRISPR-altered human embryos found 16% had these "unintended editing outcomes" at the targeted DNA, and genetic screening of edited IVF embryos might not catch these errors. Stem cell researcher Dietrich Egli hopes to find a way to start and stop CRISPR at the embryo's single-cell stage. In a preprint posted on bioRxiv on 10 March, Egli's group demonstrated a strategy for trisomy, an errant third chromosome, by targeting an extra paternal or maternal chromosome copy with a CRISPR cut at or near its centromere.
If CRISPR does not correct the trisomy in all of the cells in an early embryo, a natural "rescue mechanism" might eliminate the abnormal cells. However, there are still multiple obstacles to overcome. Researchers are trying to use CRISPR to edit human embryos but need help beyond science. Editing the DNA of egg or sperm precursor cells may avoid some of these hurdles, improving the odds of getting it right. Orwig's team is exploring a different route to creating edited sperm stem cells by reprogramming adult human cells into a stem cell state and trying to coax them partly down the pathway that produces sperm. However, reprogrammed adult cells only survive when placed into newborn animals, which is unrealistic for humans. Scientists say the increased awareness of CRISPR's shortcomings has underscored the recklessness of transplanting edited embryos with today's technology. Still, some scientists are openly advocating for the practice.
find something interesting and 1-2 questions about the summary
Answers
One interesting aspect of the article is the discussion around using CRISPR to edit disease-causing mutations after birth, rather than in embryos.
What is the authenticity if genetically modifying babies ?Fyodor Urnov supports this approach and believes that there is no circumstance that would justify modifying babies genetically. This raises the question of whether there is a moral or ethical line that should not be crossed when it comes to genetic modification of humans, even if it is done to prevent or treat disease.
Another interesting point is the potential use of CRISPR to edit the DNA of egg or sperm precursor cells to avoid some of the hurdles of editing embryos. This raises the question of how this approach would be implemented and regulated, as it involves altering the genetic material of potential future offspring before they are even conceived.
Overall, the article highlights the ongoing debate and ethical considerations around the use of CRISPR for genetic modification in humans, as well as the need for continued research and oversight to ensure that any such use is safe and ethical.

92ml 3.0 fl oz what is the ratio
Answers
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
