True or False: King Tut is a famous historical figure because he greatly expanded the Egyptian empire during his reign
Answer:
That is false
Explanation:
Thutmose III ("the Napoleon of Egypt": reign 1479–1425 BC) expanded Egypt's army and wielded it with great success to consolidate the empire at the peak of Egypt's power and wealth during the reign of his successors Amunhotep II (reign 1427–1401 BC or 1427–1397 BC), Thutmose IV (reign 1401 – 1391 BC or 1397 – 1388 BC)
In a salt marsh in Georgia, the quantity of solar radiation reaching the ground during the summer is 7,000,000cal/m2/day. The gross productivity of the producers in the salt marsh (mostly microscopic algae) is 0.0040 g/cm2/day. The average rate of respiration (the respiration requirement) is 35% of the gross primary productivity. Ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. Calculate the net primary productivity of the system, in g/m2/day. (remember, 1 m2 = 10,000 cm2)
Answer:
NPP=26 g/m²/day
Explanation:
Important data:
1 m² = 10,000 cm²NPP = GPP - Respiration NPP= Net primary productivity of a systemGPP= Gross productivity of the producersAvailable Data:
GPP=0.0040 g/cm²/dayRespiration rate= 35% of the gross primary productivityWe need to calculate the NPP, which equals GPP - Respiration rate.
The respiration rate is 35% of the GPP. This is:
100% GPP--------------- 0.004 g/cm²/day
35% GPP ----------------X = (35 x 0.004)/100 = 0.0014 g/cm²/day
Now that we know the values of GPP and respiration rate, we can calculate the NPP.
NPP = GPP - Respiration
NPP = 0.004 g/cm²/day - 0.0014 g/cm²/day
NPP = 0.0026 g/cm²/day
Now we also know the NPP, but this value is calculated in g/cm²/day, and we need to calculate it in g/m²/day, so if 1 m² = 10,000 cm², then:
1 cm²---------------- 0.0026 g/cm²/day
10,000cm²----------X = (10,000 x 0.0026)/1 = 26 g/m²/day
Could the loss of 4% of the cerebral cortex cause the behavior changes noted in Phineas Gage?
Answer:
Yes
Explanation:
The frontal lobe is the part of the brain that controls personality, decision-making and reasoning. It is a part of the cerebral cortex and the largest in composition.
Phineas Gage was involved in an accident in which a metal rod destroyed parts of his brain. This incident however brought about a drastic change in his behavior.
This incident helped to establish the relationship between the frontal lobe and behavioral patterns.
Ecologists alone cannot solve environmental problems. Solving ecological problems involves a blend of ethical, economic, and political considerations. A perfect example is the decision on whether or not to build the Keystone pipeline from the Alberta tar sands to the American Gulf Coast. Identify at least three considerations in total from both sides that are critical to this debate.
Answer and Explanation:
Environmental impact: One of the most discussed topics is that the Keystone XL might be constructed as a shortcut in an area characterized by being a fragile and sensitive ecosystem. This section addition will cause important and harmful environmental impacts in Nebraska’s Sand Hills region. Environmental impact: Another important impact is that oil extraction from the Alberta oil sands, involves a process that requires far more energy, more water, more fuel, and results in an important carbon dioxide emissions. This extraction is much more damaging than conventional oil and gas extraction. Economic impact: This project might generate so many jobs that it is argued to be good for the economy. Most jobs are thought to be temporary in two years lapse of time. But there would also be some permanent jobs. Economic impact: Keystone XL construction might enhance energy security. Economic impact: The project also estimates to contribute in a possitive way to the economy of the United States.I really need these answers. Please no bs answers.

Explanation:
calculate the growth rate for a population of 1,200 with a carrying capacity (K) of 2,000 and a maximum per capita growth rate (rmax) of 0.3.
Answer:
144
Explanation:
Population growth rate refers to the measure of how a population (N) changes over a particular time (t). Hence, it is termed as (dN/dt) where d represents the change.
The logistic population growth rate equation is given as:
dN/dT = rmaxN (K-N/K)
Where; dN/dt = population growth rate
K = carrying capacity of
population
rmax = maximum per capital
growth rate
N = population number
dN/dt = 0.3 × 1200 (2000-1200/2000)
dN/dt = 360 (800/2000)
dN/dt = 360 (0.4)
dN/dt = 144
Hence, the growth rate of the population (dN/dt) is 144

list the order in which the body will consume carbohydrates, lipids, and proteins for energy, and explain why. Based on this informatoin, include what diet and excercise plan would be the best for someone trying to lose weight
Answer:
carbohydrates, lipids, and proteins
Explanation:
The above sequence is the correct other.CHO foods are easier to process breakdown by the body through glycolysis, Kreb's cyle and oxidative phosphorylation of ETC than other sources especially lipds. Hence, it is faster for the body to dispose the energy contained for biochemical activities. Specifically the oxygen required for metabolism and oxidation of CHO is very low compare to the amount needed for the same function in lipids. Therefore energy supply for CHO metabolism is the lowest and easier to extract the energy contained- as in glucose and starch.
Lipids -fats and oils have large sources of energy.But the longer process for metabolism(as stated above) and extracting the stored energy is longer.This is because of the longer hydrocarbon chains which must be metabolize by longer oxidative phosphorylation process, for required ATPs to be obtained.However,the energy storage is high due to more Protons for electrochemical gradients.
Proteins take longer period to undergo metabolisms in the body. This reflects in the complexity of the macro molecules they are made of.Therefore release energy at a slower rate,but long lasting compare to CHO. This is because the sequence of oxidative phosphorylation takes longer period to generate ATPs.
Protein is the ideal diet to embrace if to loose weight.
This is because,proteins usually suppresses the activities of hunger hormones,Thus the individual eat less,but increases the secretion of Leptin. This is a satiety hormone,an hormone that suppressed appetite,Hence, the individual eat less, consume lower amount of calories and therefore loose weights.

In your own words, describe the purpose and process of translation. The purpose of translation is… The process of translation is...
Answer:
the purpose of the translation is to make proteins. proteins are responsible for making bones, muscles, cartilage, skin and blood. proteins are synthesized from the information in a mRNA.
Process of translation
it happens in 3 phases
initiation: the small ribosomal subunits binds to the start of the of the mRNA sequence. then a tRNA molecule carrying the amino acid methoionine binds to start codon of the mRNA sequence. after that large ribosomal subunit binds to form the complete intiation complex.elongation: the ribosome continues to translate each codon in turn each corresponding amino acid is added to the growing chain and linked via bond called peptide bond. elongation continues untill all the codons are read.termination: it occurs when the ribosome reaches a stop codon. since there is no tRNA molecules that can recognise these codons the ribosome recognises that translation is complete.after these 3 phases a new protein is realeasd
Explanation:

Do you think the processes that form and shape the small stream bed are similar to those that form and shape the Grand Canyon? Why or why not?
Answer:
Yes.
Explanation:
The processes that formed the small stream bed are similar to those that formed the Grand Canyon because both are formed by the flowing of river. The river flow through these regions and with this flow they takes rock particles with itself and makes several shapes and structures of that region. So we say that rivers and streams are responsible for the formation of stream bed and Grand Canyon.
