Darwin suggested that plants pollinated by long tongued insects would benefit by having long flowers. To measure the advantaged of having long flowers, Johnson and Steiner (1997) experimentally shortened 68 of 140 flowers. The remaining flowers were control. One week later, 24 out of the 68 shortened flowers had received pollen, whereas 18 out of the control flowers had received pollen. Estimate the odds ratio of not receiving pollen after flower shortening, as compared to control flowers
Answer:
The possibility of not receiving pollen for shortened flowers is 64.7% and for the control group it is 75%.
Explanation:
Pollination carried out by insects help plants spread their pollens and multiply. Contrary to Darwin's suggestion, the experiment results prove that having long flowers decreases the chances of pollination by long tongued insects as it is shown in the experiment.
The odds ratio of not receiving pollen after the flower shortening can be calculated as 64.7% compared to the odds of flowers that were not shortened which have a possibility of 75% of not receiving pollen.
I hope this answer helps.
What can we do in lieu of a breathable atmosphere
Answer:
Explanation:
I wonder how you would explain that both men and women are living much longer. In 1900 the average ago of mortality was 42 years old in the United States. We have nearly doubled that. In the province (Canada) where I live the mortality rate is nearly 81 years old. That is a huge improvement.
We have done in spite of contaminated air, oceans that resemble sewage sump (there is a plastic dump the size of Texas somewhere in the Pacific and the Atlantic is little better), a population increase that is unbelievable in terms of %. I wish my stocks would show that kind of % increase, and the current biological crisis -- I'm not allowed to name it. (There have been several of these pandemics since 1900.)
So I'll ask again: How are such things to be explained.
Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenate into a pellet in the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains
Complete question:
Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenates into a pellet at the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains
1. peroxisomes
2. mitochondria
3. lysosome
4. Golgi complex
5. endoplasmic reticulum
Answer:
2. Mitochondria
Explanation:
Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.
The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.
Mitochondria are more grouped in areas or tissues with higher energetical requirements.
As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.
By considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.
Cellular respiration is a series of reactions by which aerobic cells consume oxygen and nutrients (e.g. glucose) to produce ATP and carbon dioxide.
Cellular respiration has three sequential steps: glycolysis, the Krebs cycle and oxidative phosphorylation.
Mitochondria are the energy center of the eukaryotic cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria, while glycolysis occurs in the cytoplasm.
The Krebs cycle produces a four-carbon molecule known as succinate.
Adenosine triphosphate (ATP), the energy coin of the cell, is produced from ADP and phosphate (Pi) in the three stages of cellular respiration.
Finally, oxygen is consumed during oxidative phosphorylation.
In conclusion, by considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

What is digestion and how does it work
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.
In an experiment on synaptic transmission, a synapse was bathed in a Ca+2- free medium that was otherwise equivalent to extracellular fluid. An action potential was triggered in the presynaptic neuron. Although the action potential reached the axon terminal at the synapse, the usual response of the post synaptic cell, did not occur. What conclusion would you draw from these results? Explain your answer.
Answer:
Response of the postsynaptic cell is dependent on the neurotransmitter release
Explanation:
Calcium (Ca2+) is essential for the propagation of the action potential since it is required for neurotransmitter release. When an action potential reaches the end of an axon, voltage-dependent Ca2+ channels open and Ca2+ ions bind to regulatory proteins, thereby initiating the release by exocytosis of neurotransmitters contained in the presynaptic vesicles at the synapse and modulating the transmission of a signal to another neuron (i.e. the postsynaptic site).

Explanation:
You are studying a new gene "X" that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xfp
Answer:
The correct answer is - 1103 bp.
Explanation:
PCR or polymerase chain reaction is a process that uses a primer to amplifying the desired segments of DNA molecules. It is a technique that can amplify a million copies of the DNA segment.
given:
forward primer binds from - 32 to 47
reverse primer binds from - 1135 to 1110
PCR product would be between - 32 to 1135
So, product size would = 1135-32 = 1103.
Thus, the correct answer is - 1103.
g To generate a vaccine to pertussis toxin, a heat-killed preparation of Bordetella pertussis (the bacteria that produce pertussis toxin) is mixed with a purified preparation of the inactivated toxin protein.

Explanation:
Suppose the 3' splice site is mutated from AGG to ACG. Predict the consequence of this mutation. Choose one: A. Splicing would occur as normal because this splice site is less important than the 5' splice site. B. Splicing would occur as normal but there would be a point mutation in the mRNA and final protein sequences. C. Splicing would not begin if the 3' splice site is altered. D. Splicing would begin but not be properly completed if the 3' splice site is altered.
Solution :
The correct order of the RNA splicing is :
1. The BBP and the U2AF is to bind the A in branch point site in the intron, but the U1snRNP binds the 5' splice site.
2. U2snRNP helps to bind the branch point site while U4/U6 and the U5snRNP binds the 5' slice site.
3. 5' end of intron binds branch point adenine and forms a lariat.
4. Conserved adenine in branch point site attacks 5' splice site thus cutting the RNA at 5' splice site.
5. Lariat is released and then degraded.
6. The 3' end of first exon interacts with 3' splice site and forms a new bond in the sugar phosphate backbone.
When the 3' splice is altered, then the splicing begins but are not properly completed due to the altered activity of the full introns that will be present in mRNA.
