Courtney is making regular observations of the growth rate of kudzu vines on a ditch in her neighborhood. She isolated and tagged five tendrils of the vine, and takes weekly cumulative measurements for a year. A portion of her results are shown below. What issue with her data does Courtney need to resolve? Tendril #


Week 1 Week 3 Week 6


1 1.2 cm 5.9 in 1.2 ft


2 2.0 cm 4.8 in 0.98 ft


3 0.8 cm 3.2 in 0.55 ft


4 0.2 cm 1.6 in 0.35 ft


5 1.5 cm 4.3 in 1.01 ft


A) Inconsistent units of measure

B) Insufficient amount of data

C) Duration of the study

D) Number of samples

Answers

Answer 1
Answer:

Answer: A. Inconsistent units of measure

Explanation:

When taking data such as measurements, it is very important that the results are reported in the same unit of measure. Failure to do so will eventually affect your analysed result.

Answer 2
Answer:

Answer:

A) Inconsistent units of measure

Explanation:

Since Courtney measured the same variable in all the tagged tendrils, the unit of measurement is supposed to be the same. Before any further processing or analysis of the data, she will need to use the appropriate conversion factors to convert all the variates to the same unit.

The research lasted for a whole year and data were collected weekly, the issue of insufficient data or duration of study does not arise in this case. Also since, the size of study population was not indicated, it will be be difficult to point out the sample size as an issue.

The correct option is A.

Which structure has the least effect on the ability of a virus to infect and replicate in a host cell?

Answers

The answer is an envelope.

A virus is an infectious agent that can replicate only inside a host cell. When it is outside the cell, it consists of genetic material coated with protein capsid. Some viruses also have an envelope which covers capsid. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.

A news article discussing the evolution of domestic dogs from wolves included this statement: "On its way from pack-hunting carnivore to fireside companion, dogs learned to love-or at least live on-wheat, rice, barley, corn, and potatoes." What is more scientifically accurate way to state what happened with dogs?A) Dogs were created at the same time as wolves.
B) Being around humans represented an advantage, so wolves were able to take advantage of that by changing their digestion to be able to eat wheat, rice, barley, corn, and potatoes.
C) Dogs mutated to be able to eat wheat, rice, barley, corn, and potatoes.
D) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.

Answers

Answer:

The correct answer will be option-D

Explanation:

The studies done by the scientist led to the conclusion that the doges were evolved from the wolves,

The interaction of the wolves with humans became symbiotic around 10000-15000 years ago when the wolves in search of food changed themselves and adapted to survive with humans.

The studies on the genes of Dog shows that the gene responsible to digest carbohydrate called amylase starting duplicating in Wolves allowing them to digest carbohydrate cereals offered by humans. Their pancreatic enzymes also got modified to digest the carbohydrate-protein rich cereals.

Thus, option-D is the correct answer.

Use the models that you created in Lesson 2, Lab 1 to help you answer the following question. Compare the surface area to volume ratio of a large cell to that of a small cell.

Why does the ratio of surface area to volume increase with the decrease in cell size?


A. A larger cell has more surface area than volume.
B. A smaller cell has more surface area than volume.
C. A smaller cell has more volume than surface area.
D. A smaller cell has an equal ratio of surface area to volume

Answers

Answer:

B

Explanation:

This is a question more about understanding ratios than understanding cells.

A surface area to volume ratio (S/V) in a size-decreasing cell would increase due to a more significant loss in volume that in surface area. In reality, both decrease (surface area AND volume), but as we are talking about a ratio, this one would go up due to a more dramatic decrease in volume.

B. A smaller cell has more surface area than volume. This allows for more reactions to occur across the various membranes of the cell.
