The stages of mitosis were originally defined by cellular features observable through a light microscope.
a. True
b. False
Answer: TRUE
Explanation:
The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:
--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.
--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.
--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.
--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

Taiga is considered as the driest moist biome because, it rains as little as the temperate rain forest, but retains most of its water throughout the year because of the cool temperatures.
What is taiga forest?In North America, Taiga is generally referred to as boreal forest or snow forest. This is world's largest biome, consist of cone bearing seed plants, mostly, of pines, spruces, and larches.
It covers most of inland Canada, Alaska, and parts of the northern contiguous United States in North America. In Eurasia, it covers most of Sweden, Finland, Russia from Karelia in the west to the Pacific Ocean, Norway and Estonia, some Scottish Highlands.
Throughout the year, taiga experience relatively low precipitation. Primarily it rains during summer, but can also be snow or fog. Due to low evaporation rate, it is sufficient for vegetation growth.

The teacher noticed that Carrie seemed quite restless today and was having difficulty concentrating on any task that she started. She continuously squirmed, whether in her chair or sitting on the floor. On a number of occasions, the teacher also observed Carrie tugging at her underwear and scratching her bottom. She recalled that Carrie’s mother had mentioned something about getting her younger brother tested for pinworms and wondered if this might be what she was observing.
Required:
If Carrie does have pinworms, for what length of time should the other children be observed for similar problems?
Answer: Other children should be observed after the average of 6 weeks from the time of exposure to Carrie who is suspected to be infected by Pin worm.
Explanation:
Pin worm also called enterobiasis vermicularis is a parasitic nematode. The eggs are found in the specimen collected from the perianal skin and in the faeces of an infected individual. In its worldwide distribution, children are more commonly infected than adults. This is so because autoinfection by swallowing infective eggs is common in children. The eggs cause intense irritation and scratching of the infected area leads to the fingers becoming contaminated with eggs. This was observed by Carrie's teacher, as she usually scratch her bottom.
Other children should be observed after the average of 6 weeks from the time of exposure to infective eggs. This is because of the direct life cycle exhibited by the worm. Following ingestion of infective eggs, the larvae hatch in the intestine. Occasionally larvae hatch from the eggs on the perianal skin and migrate back into the intestine where they grow into mature worms. This type of infection is called RETROINFECTION. The larvae develop into fully mature worms in the large intestine. The female worms migrate to the rectum, pass out of the anus and lay their eggs on the perianal skin and perineum. The eggs are produced about 6 weeks after infection. They can remain viable on bedding, clothing, household objects, and in dust for several weeks.
Therefore from the life cycle of the worm, similar problem found in Carrie can be observed in other children after about six weeks of exposure to the infective eggs of the worm.

During which process does heat transfer occur because of density differences in water or air?
A. Conduction
B. Pollution
C. Radiation
D. Convection
2. Explain your answer.
Answer: D. Convection
Explanation: As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes denser and sinks.
Answer:
The correct answer is D. Convection.
Explanation:
Convection occurs due to the differences in density, and only happens in gases or liquids. The heat is transferred by the movement of a heated fluid, which is air or water.

These coal-powered factories had caused huge damage to the environment. As a result, the government enacted anti-pollution laws to preserve and protect the environment. Predict what would happen to the white-colored moth population when the environment is restored?
Answer:
it would drastically increase
Explanation:
Studies have shown that the increased amount of pollution has led to a drastic decline in the number of white-colored moths. Therefore, if pollution decreased and the environment was restored, then white-colored moths would once again thrive and their population would drastically increase. This is because, with less pollution, the white-colored moths are much harder for predators to see and are able to blend in easier with their surroundings. This therefore, allows them to survive long enough to reproduce.

Describe at least two costs and two benefits of using a desalinization plant to obtain more freshwater?
Answer:
Advantages:
1. provide drinking water in desertic regions
2. excellent water quality
Disadvantages:
1. high cost to obtain freshwater
2. possible harmful effects on the aquatic ecosystem
Explanation:
Desalinization plants are centers that provide an independent source of water, critical for human needs. Desalination plants function to remove salt from seawater, thereby turning this water into potable drinking water, which is of vital importance for areas where freshwater is scarce (e.g., desertic regions). Moreover, desalinization plants meet (or even may exceed) standards for water quality because they are prepared to remove impurities (not only salts) from seawater. Nonetheless, desalinization plants may also exhibit disadvantages. In the first place, desalinization is an expensive process that requires an important amount of electricity to push water through a filter (desalinization occurs via reverse osmosis). Finally, desalinization plants may alter aquatic ecosystems in a negative way since the discharge of seawater modifies the salinity and decreases the oxygen levels in the water at the disposal site.
How did the results of Meselson and Stahl's experiment confirm that
DNA replication is semi-conservative? Describe the results in terms of
how replication occurs.
Answer: Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. ... From the patterns of DNA labeling they saw, Meselson and Stahl confirmed that DNA is replicated semi-conservatively.

The virus first hypothesis, suggests that:
a.
viruses evolved from the living cells
b.
viruses may have been the first self-replicating entities
c.
viruses originate from bacteria cells
d.
viruses don't evolve
Answer:
b.
viruses may have been the first self-replicating entities
Explanation:
The “virus-first” hypothesis states that viruses predated cells and contributed to the rise of cellular life. A significant proportion of all the viral genomes encode for genetic sequences that lack clear cellular homologs. Presence of such virus-specific sequences provides support to their unique origin.

A team of students from UGA are completing and field study to determine the impact the American alligator has on ecosystems in places such as the Okefenokee Swamp in South Georgia over a 3-month period. In one area, they have removed the alligators and in another area they have left the alligators. Which of the following represents the independent and dependent variables being tested in the field study as well as a claim of the predicted outcome?
Answer:
Alligators is independent variable and the impact on ecosystem is dependent variable.
Explanation:
Alligators is independent variable and the impact on ecosystem is dependent variable. The environment having alligators is a balance ecosystem because alligators feeds on some organisms to control their population while on the other hand, the environment which have no alligator is not in equilibrium state because some organisms increase in population and become invasive species that cause damage to other organisms so environment having alligators is good as compared to no alligators.
