Answer:
The difference between ethical, and finally scientific questions, are based upon their root word. Such as an ethical question may involve race and heritage, while a legal question may involve anything that involves the law such as court questions and can be resolved by the judge not the jury. Finally scientific questions can involve a question thats mainly based around science such as items that you can test or measure.

In how many revolutions can a bicycle
wheel of diameter 4.9 m cover a dis-
tance of 46.2 km?
Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000

what is the question?
Explanation:
Study the following statements, which compare the method of fermentation preferred by yeasts to they type of fermentation that may occur in human muscle cells. i. Yeasts produce CO2 during fermentation, but human muscle cells do not. ii. Different metabolic end products result from the two types of fermentation. iii. Yeasts produce more ATP per glucose in their fermentation than do human muscle cells. Choose the correct answer from below.
Answer:
Only one of the three statement is true; and that is,
(ii.) Different metabolic end products result from the two types of fermentation
Explanation:
Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.
Fermentation is carried out by many organisms including man.
In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.
In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.
From the options provided in the questions, the correct option is:
Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.

What is Nuclear Transplantation?
Answer: Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte, and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state.Nuclear transfer is a form of cloning.

As a genetic counselor, you advise couples about the possibility of genetic disease in their offspring. This morning you met with an engaged couple, both of whom are phenotypically normal. The man, however, has a brother who died of Duchenne-type muscular dystrophy, an X-linked condition that results in death before the age of 20. The allele responsible for this disease is recessive. His fiancee, whose family has no history of the disease, is worried that the couple's sons or daughters might be afflicted.
Requied:
a. How would you advise this couple?
b. The sister of this man is planning to marry his fiancée's brother. How would you advise this second couple?
Answer:
a. This couple should not worry.
b. This couple should worry.
Explanation:
a. The man should not be worried. This is because he is normal (phenotypically).
b. They should be worried because the sister of the man can be a carrier of the recessive allele. If she was a carrier, then half of their male children can be affected.

It tries to improve a specific trait like drought resistance.
The modified organism could breed with native organisms and alter the offspring's ability to adapt.
Pest populations will adapt to the modifications in crops.
There are some concerns regarding genetic engineering.

The modified organism could breed with native organisms and alter the offspring's ability to adapt. Otherwise, trick question, all are true.
At least I can guarantee the first, third, and fourth are true. The second one is maybe also half true, but if you must pick one, choose that one.
The functions of two physical structures of plants are described below:
Structure 1: Holds the leaves of the plant toward the light.
Structure 2: Helps reduce water loss.
What statement is true about the functions?
Structure 1 is the stamen and Structure 2 is the pistil.
Structure 1 is the stem and Structure is the waxy covering.
Structure 1 is the pistil and Structure 2 is the fuzzy hair.
Structure 1 is the waxy covering and Structure 2 is the stamen.
Answer:
b
Explanation:
the structure will continuously move and compete for sunlight
the wax is so that the moisture has to go thought it and will either be part of the wax or be absorbed back into the plant
The statement which is true about the functions is structure 1 is the stem and structure 2 is the waxy covering with respect to their functions.
What do you mean by Water loss?Water loss in plants may be defined as the process of evaporation of water to the atmosphere from the leaves of a plant in the form of water vapor.
The stem is the part of the plant that holds the leaves of the plant toward the source of light. While the waxy covering is responsible for the process of transpiration in the plants.
Therefore, the statement which is true about the functions is structure 1 is the stem and structure is the waxy covering.

Biotic factors are the _____things in an environment? Multicellular, Eukaryotic, living or used to be living, Non living
Answer:
living
Explanation:
Biotic factors are the living parts of an ecosystem. Because of the way ecosystems work – as complex systems of competition and cooperation, where the action of every life form can effect all the others – any living thing within an ecosystem can be considered a biotic factor. Biotic factors such as soil bacteria, plant life, top predators, and polluters can all profoundly shape which organisms can live in an ecosystems and what survival strategies they use. Eukaryotic unicellular living beings Living beings that are made up of one single eukaryotic

Answer:
1. An evolutionary trait that is homologous within groups of organisms (see homology) that are all descended from a common ancestor
2. Derived traits are those that just appeared (by mutation) in the most recent ancestor -- the one that gave rise to a newly formed branch.
3. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor.
4. It helps us to form a cognitive framework of understanding complexity.
5 Because it is a learned trait. For some domains, like Bacteria and Archeabacteria, DNA is transferrable

P = dominant allele for color, purple
p = recessive allele for color, white

O All are tall and purple
O Three-quarters of the plants are short and white
All are short and white
Three-quarters of the plants are tall and purple
Answer:
A. All are tall and purple
Explanation:
When you set up a punnet square, all of the results would be TtPp.
When a dominant trait is present, it preceeds over the recessive trait. (Also it depends on what genotypes are given. Ex: In flowers if they gave RR shows red, Rw shows pink, and ww shows white, but that's not the case here given that there are only 2 genotypes).
So to break it down:
Tt -> tall plant
Pp -> purple plant
so they are all tall and purple.
None of the above
