Answer:
“Geoneutrinos,” neutrinos that stream naturally from the Earth’s interior, are giving scientists the best direct evidence of what’s at work in the belly of the planet. Released by naturally occurring radioactive isotopes inside the Earth, geoneutrinos carry information about what makes the Earth’s insides hot; what elements make up the core of our planet and in what concentration and distribution; how the Earth’s mantle and tectonic plates move and interact; and how planets like our own form and evolve.

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.
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.

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.
What is you were an astronaut and interplanetary explorer and you discovered “something” on another planet,like Mars that reproduced by itself, grew in size, took in food, responded to you or other stimuli, but did not seem to be made of cells or possess DNA or RNA. would you consider it to be living or nonliving?
Answer:
I would consider it to be nonliving
Explanation:
The characteristics of life demarcates a living thing from a nonliving thing. These characteristics include the ability to move, ability to respire, ability to reproduce, ability to undergo nutrition (take in food), ability to respond to external stimuli, ability to grow by increasing in size and more importantly must be made up of at least a single cell. Cell is the fundamental and basic unit of all living things.
This object found in Mars may be able to perform every other characteristics of a living thing e.g reproduction, irritability, growth, nutrition etc but to be considered as a living thing, it must consist of at least one CELL, which in turn must contain either a DNA or RNA molecule that carries information about its genetic content.
Hence, according to the universal CELL THEORY that states that "All living things contains one or more cells", this something found on Mars is not considered living.
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
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.please please help!!

Most endocrine tissues use a negative feedback mechanism for homeostasis. Which of the following involves a positive feedback mechanism? Group of answer choices cortisol insulin oxytocin thyroid
Answer:
The correct answer is: Oxytocin.
Explanation:
Feedback mechanisms are key elements in the regulation of hormone release and, in the human body, most endocrine systems work by making use of negative feedback, which means that the response generated by the release of the peripheral hormone (for example, insulin), will lead to an inhibition of the stimulus that made the release of said hormone possible - this is very important to control homeostasis.
Positive feedback, on the other hand, is the opposite. This type of feedback mechanism, which is not as common as negative feedback, happens when the peripheral hormone is released and this stimulates the tissue that released the hormone that stimulated the release of the peripheral hormone - this is done so the hormone effect is amplified more and more.
To better illustrate these mechanisms, here are some examples of each:
Insulin. After having a meal, the blood sugar levels rise, which triggers the release of insulin, a hormone that decreases blood sugar levels (glycemia). When this decrease in glycemia is produced, the release of insulin is stopped. This is negative feedback. Cortisol and thyroid hormones are also examples of negative feedback.Oxytocin. This hormone is released from the posterior pituitary gland during labor to produce the contractions of the uterus, which will push the baby through the birth canal. The presence of oxytocin will lead to the release of more oxytocin, so the muscle contractions can increase. This is an example of positive feedback.Convert the following:

a. 15,000
b. 1500
C. 150
