a. True
b. False
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.
the inclusive wealth index was created as a replacement for gdp for which reason, failure of GDP to account for literacy rate, unemployment rate, wealth, or resources within a nation
Answer:
failure of GDP to account of wealth.
Explanation:
the main reason for the creation of inclusive wealth index as a replacement for GDP because GDP can't tells us about the multi-dimensional nature of development. The inclusive wealth index measures the wealth of nations with the help of comprehensive analysis of production of a country. That is, it measures all of the assets including manufactured, human and natural capital of the country GDP is an indicator of a standard of living of a society while on the other hand, inclusive wealth index is an indicator of the wealth present in a country/

What will happen to the red blood cell in this environment?
A. The size of the red blood cell will remain constant.
B. The red blood cell will swell at first and then shrink.
C. The red blood cell will swell from absorbing salt molecules.
D. The red blood cell will shrink from losing water molecules
Answer:
3. D. The red blood cell will shrink from losing water molecules
59. C. Glucose + Oxygen —> Carbon dioxide + Water
Explanation:
The red blood cell has a lower salt concentration than the liquid which means that it has a higher water concentration than the liquid.
By the process of osmosis, water will flow from the red blood cell to the liquid which would lead to the red blood cell shrinking in size.
Cellular respiration is used to create energy for cells. It works by burning glucose in the presence of oxygen. The result is an outburst of energy and CO2 as well as water.
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.
Why is the taiga (boreal forest) considered "the driest moist biome" ?

5. What does EGS stand for in geothermal energy?
A) Engraved Geothermal System
B) Enhanced Geothermal System
C) Exhaust Gas System
D) Engineered Geophysical System
(EGS) stands Enhanced Geothermal Systems which can greatly increase geothermal energy utilization. Therefore, option (B) is correct.
What is EGS?Enhanced Geothermal Systems (EGS), which are also referred to as engineered geothermal systems on occasion, present a significant opportunity for significantly broadening the application of geothermal energy.
In an EGS, fluid is injected into the subsurface under conditions that are carefully regulated. This causes previously closed cracks to reopen, which in turn creates permeability in the rock. The increased permeability of the rock makes it possible for fluid to move freely within the newly fractured rock and for heat to be transported to the surface, where it can be used to create electricity.

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.

Select the statement below that describes a critical finding of the Franklin DNA diffraction experiment. Group of answer choices That the phosphate groups are stabilized by the presence of divalent metals in solution That base stacking is the primary force holding the DNA helix together That B-form DNA helices have a pitch of approximately 34 angstroms That the DNA bases are predominantly found in their keto form That the number of adenine residues is always equal to the number of thymine residues in a double stranded DNA molecule
Answer:
That B-form DNA helices have a pitch of approximately 34 angstroms
Explanation:
Rosalind Franklin was an X-ray crystallographer whose work contributed to the discovery of the molecular structure of DNA molecule by Watson and Crick. B-form DNA is the most common form of DNA, which consists of a right-handed double helix. B-form DNA was discovered by Watson and Crick based on the X-ray diffraction image of DNA (popularly known as image 51) obtained by Franklin. The pitch refers to the distance after every 10 base pairs along the DNA helix for one complete double-helix turn. This distance in the B-DNA helix is 34 Ångströms (i.e., 3.4 nanometers).
if bread is exposed to air at room temperature, fungi inevitably colonize it. what does this say about the presence of fungal spores in our environment?
Answer:
This supports the fact that fungal spores exists in the atmosphere or air
Explanation:
Fungi is a kingdom of living organisms that have distinguished characteristics from plants and animals. They propagate themselves using structures called SPORES. Some of these spores are able to withstand extreme or adverse unfavorable conditions and germinate when conditions are favorable. Most fungal spores are air-borne i.e are dispersed by air.
According to the information in this question, Fungal spores will colonize bread that is exposed to air at room temperature. This implies that fungal spores are present everywhere in the atmosphere looking for opportunities to germinate. The bread is a place conducive for fungal growth due to the presence of nutrients and a favorable temperature.
