Theoretically, P.bursaria can obtain zoochlorella either vertically (via the asexual reproduction of its mother cell) or horizontally (by ingesting free-living Chlorella from its habitat). Consider a P. bursaria cell containing zoochlorellae, but whose habitat lacks free-living Chlorella. If this cell subsequently undergoes many generations of asexual reproduction, if all of its daughter cells contain roughly the same number of zoochlorellae as it had originally contained, and if the zoochlorellae are all haploid and identical in appearance, then what is true?
A) The zoochlorellae also reproduced asexually, at an increasing rate over time.
B) The zoochlorellae also reproduced asexually, at a decreasing rate over time.
C) The zoochlorellae also reproduced asexually, at a fairly constant rate over time.
D) The zoochlorellae reproduced sexually, undergoing heteromorphic alternation of generations.
E) The zoochlorellae reproduced sexually, undergoing isomorphic alternation of generations.
what are toes inside of the human body and what do they produce?
Answer:
Each toe consists of three separate bones and two joints, except for the big toe, which has only two bones — distal and proximal phalanges — and one joint, like the thumb in the hand. The phalanges are made up of the distal phalanges at the tip, middle phalanges, and proximal phalanges, closest to the metatarsals.

What happens as people consume more forests?
O A. The total supply of forests increases, and biodiversity decreases.
B. The total supply of forests and biodiversity both increase.
C. The total supply of forests decreases, and biodiversity increases.
D. The total supply of forests and biodiversity both decrease.
Answer:
D
Explanation:
Just took the test
When people consume more forests than usual than the total supply of forests and biodiversity both decreases. Thus, the correct option will be D.
What is forest and biodiversity consumption?Forest biodiversity refers to the diversity within the forests at the three different levels. Forest biodiversity includes all the species of plants, animals and microorganisms which are occurring in the forest, not only the tree or plant species.
Many natural products and resources are consumed at the local level by human beings. However, we neither sell nor buy these resources. These resources do not make direct contribution to the nation's economy and wealth. The value of these different products is called as the consumptive use value of forest biodiversity.
When people consume more forests than this may result in the decrease of both the total supply of forests and biodiversity.
Therefore, the correct option will be D.

Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere
Answer:
Ocean plays the role of regulator.
Explanation:
The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.

if the pressure of a sample of gas is doubles at constant temperature, what happens to the volume of the gas?
Answer:
If the pressure doubles, the volume decreases in half.
Explanation:
The relationship between the pressure and the volume of a gas can be explained by Boyle's Law. According to this law, the volume and pressure of the gas has an inversely proprietary relationship. In that case, if the pressure on the volume decreases in the same intensity and if the pressure decreases, the volume increases in the same proportion. In that case, if the pressure of a gas sample doubles, the volume decreases by half.
The CJ bacteria in the chickens at Monita Farms have a high frequency of the allele that causes FQ resistance. If genetic drift was the cause, would this allele also be in bacteria at the Original Farm?
Answer:
Yes
Explanation:
Genetic drift refers to a random change in the allelic frequency of a population through many generations. The founder effect is an especial case of genetic drift. Yes, the resistance allele was also at the Original Farm.
--------------------------------------
Before answering, let us review some framworks.
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population. Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition.
The exposed example refers to a founder effect -genetic drift- event.
Some chickens were taken from the original population to another farm.
Bacteria in these chikens could or could not be genetically representative of their original population.
What does it mean?
It means that probably the allele that causes resistance was present in the original population.
Individuals carrying the allele were taken to the new farm where it randomly increased its frequency.
So in the new farm the new population expresses a high frequency of the resistant allele.

What was the shape of the diffraction pattern of DNA that made them conclude that it was a Double-helix?
Answer:
The diffraction pattern was as an X
Explanation:
Rosalind Franklin was an X-ray crystallographer who discovered that the DNA molecule existed in a helical conformation. She used X-ray diffraction to determine that the pattern of the DNA molecule was as an X, thus showing that the DNA molecule formed a spiral (i.e., a double helix), which was key in helping Watson and Crick to elucidate the structure of the DNA molecule. Otherwise, if DNA would be a lineal molecule, it would be seen as two dots under X-ray diffraction.
