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?

Answers

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

Answers

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.

A scientist separates a population of lizards into two groups. What would
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.

Answers

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.

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.

Answers

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.

Using the codon chart, what is the sequence of amino acids that is produced when this RNA is translated?

Answers

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).

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.
