Red-flowered snapdragons are crossed with white-flowered snapdragons, producing all pink snapdragons in the F1 generation. What would you expect if you crossed pink with pink? The choices are... (1/2, 1/4, 3/4) red, (1/2, 1/4, 3/4) pink, (1/2, 1/4, 3/4) white.
Answer:
Red (1/4), Pink (1/2), white (1/4)
Explanation:
This question involves a single gene coding for flower colour in the snapdragon plants. The gene exhibits incomplete dominance, because the allele for red color (R) is incompletely dominant over the allele for white color (W), hence an intermediate phenotype is produced as pink color (RW).
The pink colored snapdragon plant is produced in the F1 generation. When these F1 offsprings are crossed i.e. RW (pink) × RW (pink), gametes with R and W alleles are produced by each F1 parent.
Using these gametes in a punnet square (see attached image), four possible offsprings with genotypes; RR, RW, RW and WW will be produced in the F2 generation.
RR offsprings (1/4)- Red flowered
RW offsprings (2/4 or 1/2)- Pink flowered
WW offsprings (1/4)- White flowered

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.
6CO2 + 6H2O + photons —>CGH1206+602 is the chemical equation for what metabolic process?
Answer:
This is for photosynthesis, which is anabolism.
Explanation:
The photon which represents the packet of energy from the sun,is used to split water molecules into H+.electrons and oxygen. The Hydrogen ion is used to reduce CO2 to produce CHO, fatty acid and protein in the Calvin cycle.This is photosynthesis.
Therefore, the single reaction is made up of two related reactions, The splitting of water-Photolysis.. which occurs in the daylight.The reaction is therefore called light dependent stage.
While the reduction of the CO2 with the Hydrogen ion , in the presence of ATPs, which takes place in the dark,called light independent stage.

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.
Answer:
Replace the concentration descriptions with actual values

HELPP PLSSS :) American pikas are prey to long-tailed weasels. Which change in a limiting factor would increase the carrying capacity for long-tailed weasels in a talus field within an alpine tundra? A. increase in American pika population size B. decrease in American pika population size C. increase in the long-tailed weasel population size D. decrease in the long-tailed weasel population size
Answer:
A. increase in American pika population size
Explanation:
Carrying capacity is the idea that relates to how much population can an environment sustain before collapsing. Here, the answer would be A. increase in American pika population size because if you increase the food for weasals, naturally the population carrying capacity goes up because now the environment has food to feed the weasals which can contribute to increasing the carrying capacity (i.e. the environment can now handle larger population of weasel than initial condition)
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.

Fill in the blanks below to complete the hypothesis for this lab. It should answer the lab question, "What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?" If molecules are small enough, then . . .
Answer:
They can pass through the semi permeable membrane
Explanation:
The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through
If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.
Answer:
Sample Hypothesis: If molecules are small enough, then they will diffuse across a semipermeable membrane because they can pass through its tiny openings.
-correct conclusion (“then”): Molecules will diffuse through the membrane
-correct reason (“because”): Molecules can pass through the membrane’s tiny openings.

Answer: Law of independent assortment.
Explanation:
Mendel's law of independent assortment states that genes do not influence each other while they are sorted into alleles.
Every possible gene is likely to occur. This means that the traits are passed from one generation to another generation individually not in pair of allele, sets or groups.
The characters are represented individually not in pair. Though the characters are present in pair but they are individually represent themselves and do not affect each other.

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.

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.
