1. Which of the students' observations will be most helpful in classifying a cell as either prokaryotic or eukaryotic? O Shape of the cell. O Presence of a nucleus. Presence of organelles. Visible DNA.
Answer:
B) presence of a nucleus
Presence of a nucleus will be most helpful in classifying a cell as either prokaryotic or eukaryotic. So, the correct option is B.
What are Prokaryotes and Eukaryotes?Prokaryotes are defined as those organisms which possess cells that lack membrane bound organelles. These are usually single cell organisms. Some examples of prokaryotes include bacteria, archaea, and cyanobacteria (blue-green algae).
Eukaryote are defined as those organisms which possess membrane bound organelles. These contain a central nucleus which is surrounded (bound) by a membrane called nuclear envelope. Some examples of eukaryotes include animals, plants, fungi, and protists.
Thus, the presence of a nucleus will be most helpful in classifying a cell as either prokaryotic or eukaryotic. So, the correct option is B.

Gradual speciation is more likely to be associated with small changes building up in:___________
A. ability to reproduce asexually
B. genes associated with DNA synthesis
C. geographically diverse areas
D. stable environments
Answer:
D. stable environments
Explanation:
In the gradual speciation model, changes in species are slow over time that occur in small steps. Change in speciation rate influences two factors that are environmental conditions and population size.
Gradual speciation mostly occur in large populations that move towards evolution and live in a stable environment. The stable environment provides enough time for the evolution to happen and stable habitat for the new species to grow slowly.
Hence, the correct answer is "D. stable environments".
Cells require oxygen to complete cellular respiration. What is a role of oxygen in this process?
A. combining with hydrogen atoms to form water at the end of the electron transport chain
B. combining with hydrogen atoms to form water during glycolysis
C. combining with carbon atoms to form carbon dioxide during glycolysis
D. combining with carbon atoms to form carbon dioxide at the end of the electron transport chair
For the effective utilization of glucose in cellular respiration, cells require oxygen, hence option A is correct.
What is the process of cellular respiration?The electron transporter chain in cells needs oxygen to function. It performs the role of the electron transport chain's last electron acceptor, promoting the flow of electrons down the chain and resulting in the production of ATP or adenosine triphosphate.
This is how most creatures get their energy, parts of the glucose molecules that are bound by oxygen release energy, water, and carbon dioxide.

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?
Answer:
The correct approach is "Negative and Positive".
Explanation:
Just outside of the neurons, the electrostatic interactions seem to be extremely favorable or positive (+) as well as the ion mostly with the greatest proportion was indeed sodium. Throughout intracellular space, a large amount of protein would be negatively charged, or even just potassium channels predominate. Under those same circumstances, the ion channels also seem to be inaccessible.For this specific purpose, this same lying down the neuron, before obtaining a stimulus, introduces positively charged on the external social but instead negative (-) inside though.

Which of these situations is most likely to end in fossilization?
a long life
a slow death
a quick burial
rapid decomposition
Answer:
a quick burial
The most important part: the body has to be buried suddenly, which is rare. Rapid burial can happen due to natural effects, including volcanic eruptions, which bury things in ash, or dying near a flooding stream, which rapidly covers the body in sediment.
Explanation:
Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals. These crystallized minerals cause the remains to harden along with the encasing sedimentary rock.

From which molecules are mRNA molecules transcribed?
A. tRNA
B. rRNA
C. DNA
D. protein
Answer:
C
Explanation:
mRNA molecules are transcribed from DNA molecules. Therefore, option (C) is correct.
Synthesis of mRNA molecules utilising a DNA template occurs during transcription. RNA polymerase and other transcription factors attach to particular sections of DNA known as promoters in the nucleus of eukaryotic cells. The DNA double helix is subsequently unwound by the RNA polymerase, and using one of the DNA strands as a template, it starts to synthesise a complementary RNA strand.
According to the complementary base pairing principles, the RNA polymerase adds nucleotides to the expanding mRNA strand during transcription. While cytosine (C) pairs with guanine (G), adenine (A) in DNA pairs with uracil (U) in mRNA. The mRNA molecule is released and the DNA double helix reforms once the full gene sequence has been read.

Which of the following statements is TRUE about fiber? A) Fiber is best obtained through pills and other fiber supplements. B) Consuming excessive fiber can increase C) Increases in daily fiber intake should be gradual.D) The typical american diet provides about 25g fiber a day.
Answer:
C) Increases in daily fiber intake should be gradual.
Explanation:
Fiber is the indigestible part of plants and carbohydrates. Beans, peas and lentils are some sources of fiber.
Fiber is best obtained through dried peas and beans and not from pills and the optimal amount of fiber varies with gender, age and pregnancy so there is no fixed diet for fiber and 25 g fiber a day is recommended for adult women and 38 g for adult men.
Increases in daily fiber intake should be gradual because a high fiber diet helps to prevent diseases like heart diseases, diabetes, constipation, and colon cancer. It also smoothens the digestive system and lowers the cholrestrol.
Hence, the correct answer is "C) Increases in daily fiber intake should be gradual."
what is allele frequency?
Answer:
The correct answer would be - D. the distribution of alleles in a population.
Explanation:
Allele frequency in population genetics is the term used to provide the amount of the different alleles in particular loci. In other words, it is the distribution of alleles in a population.
The term allele frequency refers to the fraction of the copies of the gene of the alleles in a known population. It can be calculated by the number of allele present of interest divided by total number of alleles in a population.

How does a stormwater runoff system store water?
Stormwater that cannot be directed back into rivers or streams is stored in
Answer:
Stormwater that cannot be directed back into rivers or streams is stored in Retention Basin's
Explanation:
Storm water that cannot be directed back into rivers or streams is stored in Retention basin.
What is Retention basin?A retention basin is also called a wet pond, wet detention basin, or stormwater management pond. It is defined as an artificial pond with vegetation around the perimeter and a permanent pool of water in its design.
Retention basins usually allow water to percolate through the soil and then into a shallow groundwater aquifer, whereas this basin can be man-made or a natural form of depression in the soil, which are closed systems, constructed in such a way that there is no storm water access to natural water bodies.
These are used to intercept and distribute rain runoff, which in turn helps prevent flooding which are often landscaped with a variety of grasses, shrubs and/or wetland plants to provide bank stability .
Thus, storm water that cannot be directed back into rivers or streams is stored in Retention basin.

BUZZ, BUZZ! Oh, what terrible timing. Tom was in the middle of setting up an experiment in lab when his phone indicated that he had a voicemail from his 3-year-old's preschool. He finished up his immediate task and checked his messages. The preschool teacher was calling to let him know that his son, Theo, had a fever of 101.7°F and that he didn't seem to be feeling well and needed to be picked up early. Tom sighed and said he would be right there. He went back into lab, diluted back his bacterial culture, put it in the incubator, and decided to do the experiment tomorrow. When he drove to preschool and picked up Theo, he noticed Theo was lethargic and sad. Tom knew that kids get all sorts of random illnesses, so he took Theo home to see if he could figure out if anything else was wrong. Because Theo was 3 years old, he was able to tell his Dad that his throat hurt a lot as he kept rubbing his throat. Theo didn't seem any to be getting any worse, so everyone went to bed. In the middle of the night, Theo wakes up to vomit (repeatedly) and complains of stomach pain.
Tuesday, March 7, 2017
After a night of not very much sleep, Tom checked Theo's temperature again and saw that it was still high. Now he saw that Theo's cheeks were flushed and there was a rash consisting of pink, slightly raised bumps (no pustules) covering his cheeks, chest, and back. Tom placed a call to the pediatrician to set up an appointment for later that morning.

a. What disease is the boy likely suffering from? Explain your diagnosis.
b. Name and describe the pathogen that causes this disease.
c. Because Theo is going to be taken to the doctor, is it likely to the fatal? What if the year was 1900? Why?
d. Explain what is causing the rash.
e. If the boy was infected with the same pathogen and had the same signs and symptoms, but did not present with a rash, what would the disease diagnosis be?
f. What treatment would the doctor prescribe? Name one example and describe the mechanism of action
