Explanation:
A study was conducted to evaluate the relationship between artificial sweeteners and bladder cancer. 3,000 cases and 3,000 controls were enrolled in the study. Among the cases, 1293 had used artificial sweeteners in the past, while 1707 had never used artificial sweeteners. Of the controls, 855 had used sweeteners and 2145 had not.
a. What is the exposure and what is the disease?
Calculate the correct measure and show your work.
How do we interpret this effect estimate?
Answer:
A. exposure - use of artificial sweeteners
disease - bladder cancer
In this research artificial sweeteners are used as the exposure that leads to bladder cancer disease.
B. Bladder cancer No bladder cancer
Artificial sweeteners 1293(a) 855(b)
No artificial sweeteners 1707(c) 2145(d)
Total 3000 3000
Cases -
- Risk factor (Artificial sweeteners) present (1293)
- Risk factor (Artificial sweeteners) absent (1707)
Controls
- Risk factor (Artificial sweeteners) present (855)
- Risk factor (Artificial sweeteners) absent (2145)
Odds ratio or strength of association between exposure and disease
OR= Cases with exposure/cases without exposure= a/c divided by b/d
So, the putting value ad/bc= 1293*2145/855*1707
= 1.9
OR would be 1.9
C. this interprets that there is a 90% increase in the chance of bladder cancer if exposed to artificial sweeteners or people with bladder cancer have a 1.90 times higher odds of using artificial sweeteners compared to controls
What are valence electrons?
A. the atomic mass
B. the atomic number
C. all of the electrons in an atom
D. electrons in the outermost energy level
Answer:
D
Explanation:
The simple answer is the electrons in the outermost energy level.
Hydrogen has 1 electron in the outermost energy level.
Magnesium has 2 so this tells you that magnesium has a charge of 2
Oxygen has 6 oxygen has a charge of - 2
Fluorine has 7
For most elements, the electrons in the most outer ring determine the valence of the element.
Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.
Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
Answer:
D. electrons in the outermost energy level
Explanation:
The valence electrons are the electrons in the outermost energy level.

most likely increase the rate of speciation in this population?
A. Have one group breed twice as often as the other.
B. Keep the two groups apart, but in identical ecosystems.
C. Force the two groups to breed with each other.
D. Have one group live with a much stronger predator.
Answer:
Hi, there your answer is D. Have one group live with a much stronger predator.
Explanation:
Having one group live with a much stronger predator will most likely increase the chances of speciation.
What is speciation?It is a process by which a new species of an organism is created.It occurs due to evolution.It occurs when a portion of population gets separated from the original population and evolves different characters that are heritable.Will speciation occur if :one group breeds twice as often as the other? No, because no selective force is acting on it.both groups are in identical ecosystem? No, since no reason for adapting and evolving a new character will be there.both groups interbreed? No, there is no competition, no struggle for existence and hence no evolution occurs.one group lives with a strong predator? Yes, since they will evolve evasive mechanisms and characters.To learn more about species, evolution, and predator here,

When someone says the word "desert," what plant do you picture? You're probably
picturing the saguaro cactus. Saguaros are known for their long, tall branches that look like
arms. These branches don't start to grow until the cactus is 50 to 70 years old. The folds
along the saguaro's stem and branches are called pleats. What are they for? These pleats
store water for the cactus, which is important in the hot, dry desert. A desert plant's spikes
aren't just to keep animals away. They also help provide shade during the long hours they
spend in the sun.

Discuss the benefits and drawbacks of
using solar energy and wind energy.
Answer:
hmm I'd say something like "Solar and Wind energy systems are renewable sources and ultimately are healthier for the planet, the drawback is that other resources (i.e oil and coal) tend to be cheaper"
Answer:
Solar Energy:-Benefits-
Solar power is completely cleanIt produces no air pollution, no water pollution, no greenhouse gas effects and carbon - free alsoNo harmful emissions are released when electricity is being produced by solar panels.It also reduces the need for finite resources.Drawbacks-
Solar Energy Storage Is ExpensiveUses a Lot of SpaceIts Weather-Dependent, slthough solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.Initial cost of purchasing a solar system is fairly high.Wind Energy:-Benefits-
Wind is a domestic source of energyIt's a clean fuel sourceIt's sustainable and causes no harmful emissions. Wind energy is a green energy source and does not cause pollution.Drawbacks-
Wind turbines are prone to noise disturbances.The wind is inconsistentWind turbines involve high upfront capital investment.Installation can take up a significant portion of land.sumone help me with these type of punnett squares and if i can text sumone so they can help me with other punnett squares that i have there due today
Using the codon chart, what is the sequence of amino acids that is produced when this RNA is translated?
Answer:
In transcription, the DNA sequence of a gene is "rewritten" in RNA. In eukaryotes, the RNA must go through additional processing steps to become a messenger RNA or mRNA. In translation, the sequence of nucleotides in the mRNA is "translated" into a sequence of amino acids in a polypeptide (protein chain).
Translation starts at a methionine (Met) codon, which specifies the amino acid methionine (Met). Translation stops at a Stop codon, which does not specify an amino acid.
Translation of an mRNA molecule by the ribosome occurs in three stages: a. initiation
b. elongation
c. termination.
During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
Translation happens in four stages: activation (make-ready), initiation (start), elongation (make longer), and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

From what you can see about the shape of HIV, explain what the problem would be with a vaccine to HIV?
Answer:
Diversity and strategies.
Explanation:
The problem would be with a vaccine to HIV is that HIV virus has diversity as well as strategies of HIV virus adopted to avoid the effect of vaccine so it can't kill the HIV virus from the body so the virus cause infection to the cells of the body again and again. The diversification of HIV strain reduce the impact of vaccine on HIV virus whereas using different strategies by the HIV virus to avoid effects of vaccine.

Electric current is the flow of ________ through a substance.
Answer:
Electrons
Explanation:
Answer:
A current is a flow of electrons for this to happen there must be a closed circuit.
- The electricity is nothing but a flow of free electrons present in the external surface of the electricity conducting substance.
The flow direction of this electron flow is also the direction of electricity flow.
- There is a type of electrical circuit which is known as the closed circuit. This circuit is completely connected with the two terminals of the battery and there are no hindrances in the path of electricity flow in these circuits. That's why current can only flow through these complete circuits.

Why did Gregor Mendel choose to use purebred plants in his experiments?
A They reproduce sexually.
B They exhibit only one form of a trait.
C They have a variety of traits.
D They reproduce asexually.
Answer:
B
Explanation:
Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.
What is Mendel's experiment?Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.
But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.
This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.
Therefore, the correct option is B, They exhibit only one form of a trait.
