Can someone please help
Answer:
P = 0.79.
Explanation:
To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).
Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.
If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.
To prove this, we can insert these values into the equation:
[tex]0.79^{2} + 2(0.79*0.21) + 0.21^{2} =1[/tex]
[tex]0.6241 + 0.3318 + 0.0441 =1[/tex]
[tex]1=1[/tex]
What is the term for the breakdown of glucose in the presence of oxygen? cellular respiration photosynthesis anaerobic fermentation
Answer:
Cellular respiration
Explanation:
Cellular respiration involves the breakdown of glucose using oxygen to produce energy, or ATP, that is used by the cell.
The breakdown of glucose in the presence of oxygen is called as cellular respiration.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Moreover, it is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Hence, it is a series of chemical reactions that break down glucose to produce ATP.

The data in the graph are the result of a paramecium being placed in a hypertonic salt solution. A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2. What change would most improve the usefulness of the graph? Replace the concentration descriptions with actual values. Plot contractions per second instead of contractions per minute. Remove the plotted points and just keep the line. Remove the name of the organism from the title.
Answer:
Replace the concentration descriptions with actual values
Explanation:
For results of this nature to mean much, they need to be able to be reproduced by a different experimenter. In order to be able to do that, the experimenter must be able to reproduce the salt concentrations. The graph would be more useful if it had the actual concentration values.

Name one disadvantage of light microscopes
Answer:
We can't examin the specimen in tbe absence of lght. We can not study the internal structures.
Explanation:
Answer:
Light microscopes do not magnify at the same level as other options.
The typical light microscope cannot magnify as closely as an electron microscope when looking at some of the world’s smallest structures. Most models are capped at 2,000 times or thereabouts, with some entry-level models offering significantly less to the user. Because the relatively long wavelength of light decreases the ability of the equipment to magnify in the small focus lens, you may not always see everything that is going on with a slide when choosing this option.

a) The important factor in osmosis is not the number of molecules. Instead, it is the number of particles in a given volume of solution. For example, one glucose molecule dissolved in water yields one particle, but one NaCl molecule can yield two ions: Na+ and Cl-. Water moves osmotically in response to the total concentration of particles in the solution.
If there is a 10% glucose solution on one side of a semipermeable membrane and 5% salt solution on the other side, what will most likely happen to the flow of water? (1 point)

Poison ivy is a weed that produces an oil which causes skin rashes. Scientists want to perform an experiment to see if poison ivy grows taller when exposed to more carbon dioxide. How should the control group in this experiment be treated?
Answer:
In these experiments the control group is compared with the comparison group.
The control group will sometime be in the presence of carbon dioxide, and will be controlled, where the analyst or researcher will take an expert position and then will compare it evolutionarily with the comparison group that the ideal would be that there is not ever a carbon dioxide
Explanation:
If we have two poison ivy research groups that are representative of the poison ivy that the researchers are looking to investigate the results will have much better credibility and will be more reliable.
On the other hand, the comparison of the two groups makes it possible to rigorously analyze whether or not poison ivy grows in the presence of this gas.
Describe how incomplete dominance and codominance, two non-mendelian traits, are different from each other.
Answer:
Incomplete dominance occurs when the dominant allele did not completely mask the effect of the recessive allele so that, the recessive allele could manifest some of its traits.Therefore the offspring exhibits some phenotype which reflects the blends of the two traits.( four O'clock flower)
However, in co-dominance(e.g AB blood group) none of the dominant allele is completely dominant over one another.That is the two allele of the same gene are present in the same offspring.Therefore the alleles shows their dominating effects, in the offspring, but no blend of the alleles as in the incomplete allele.

Which biomolecule do you think is most important in your diet? Why did you pick that biomolecule? Which biomolecule do you think is most important in cell function? Nutrition and snack foods A. List your three favorite snack foods. B Collect a nutrition label from each food. C. If any of the foods on your list don’t come in a package, you can look up the nutrition information on the Internet. D. Write a paragraph about each food. Is it a good source of carbohydrates, lipids, and protein? Would you consider this food healthy? Why or why not? 2. You may have heard the saying, “You are what you eat.” to explain what this statement means.
Answer/Explanation:
There is no single biomolecule that is most important in one's diet; however, proteins would be a fitting choice. This is because there are certain amino acids -- 9 in fact -- that our bodies cannot naturally produce and of which proteins consist. We need these amino acids to survive because they make up proteins, and proteins perform pretty much every crucial function you can think of, ranging from defense to cell signaling to structure. All biomolecules are important in cell function -- carbs are needed for your cells to burn for energy via cellular respiration (a process that yields app. 28-32 ATPs per cycle), lipids are needed for cell membranes (amongst numerous other needs), proteins are needed for the reasons above, and nucleic acids are needed for RNA and DNA.
A. Welch's, Oreos, Chips Ahoy
B. You should be able to do this.
C. Proves my point in B.
D. Yeah, generally the snacks I chose are not healthy, even Welch's fruit snacks. It's junk food and not high in protein. "You are what you eat" makes sense in the quite literal sense because your body mass, your health, and your overall physical attributes are determined by your diet, on top of exercise and your activities throughout your life.

What is avascular necrosis
HEYA!!
Explanation:
Avascular necrosis is basically the death of bone tissue due to a lack of blood supply. Also known as osteonecrosis, it can lead to tiny breaks in the bone and the bone's eventual collapse. A broken bone or dislocated joint can interrupt the blood flow to a section of bone.
HOPE IT SATISFIES YOUR ANSWER!!
Answer:
Explanation:vascular necrosis is associated with long-term steroid use and drinking too much alcohol. It's most common in people between the ages of 30 and 60 and often affects the hip.
Early stages may be symptom-free. Eventually, the affected joint may hurt when weight is put on it or when lying down.
Treatment includes physical therapy, surgery, and medications.
It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.

How do enzymes help digestion?
Answer:
Enzymes are essential for healthy digestion.
Explanation:
There are three types of digestive enzymes depending on the type of food on which they act.
Lipases are those that digest fat. After its breakdown into fatty acids and glycerin, they are synthesized by the pancreas.
Proteases are the ones that break the peptide bonds of proteins, reducing them to organic monomers called amino acids. They originate in the stomach or pancreas.
The so-called amylases break down starches and complex sugars in the diet, by breaking the glucidic bonds, releasing mososaccharides (especially glucose). There are 3 types of amylases: ptyaline, pancreatic amylase, and duodenal amylase.
The benefits of these enzymes are:
- They help digestion and reduce the so-called "acidity".
- They reduce the feeling of bloating and gas.
- Improves the digestion of dairy products.
- Food allergies decrease due to good protein digestion.
- They improve the conditions of hiatus hernia and ulcers.
