An inventor claims to have invented an artificial kidney for patients that need a kidney
transplant. Which of the following would be a reason that the scientific community might
reject this claim?

A. Previous investigations were unable to obtain the same results.
B. The inventor failed to present observations with data.
C. Investigations were performed in an unknown laboratory.
D. The device failed to follow law of conservation of mass

Answers

Answer 1
I believe the answer is B
Answer 2

All of the given options could potentially be reasons why the scientific community might reject the inventor's claim, but the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

What is an artificial kidney?

In the case of an artificial kidney, the device is supposed to filter out waste products from the blood, which is then supposed to be removed from the system in a measurable form, such as through urine or dialysis fluid. If the device fails to remove the waste products from the blood, or if it makes them disappear without a measurable output, it would suggest that the device is not functioning as claimed and may not be effective in treating patients who need a kidney transplant. Therefore, the scientific community would likely reject the inventor's claim until there is evidence that the device follows the fundamental principles of science, such as the law of conservation of mass

Hence, the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

Answers

First image shows a stationary organism whereas the second image indicates predator.

The first picture represents a leaf structure which is a part of plant and we know that plant is a stationary organism means it can't move from one place to another so that's why it is called a stationary organism.

While on the other hand, the second picture represents predator due to the presence of sharp teeth which helps the predators in catching and tearing of prey so we can conclude that first image shows a stationary organism whereas the second image indicates predator.

The first annual black Friday occured in Philadelphia in which alot of retailers attracted their key customers and made profits through the discount they placed on their products.

Black Friday was used to describe the financial crisis after the United States's gold market crashed.

Literally, black should depict something negative or loss but on the contrary, the business world uses black to describe profit.

Aristo was riding in a car and noticed a pond that was covered in algal blooms due to excess phosphorus in the water. Which of these other features in the landscape could be the reason for the high levels of phosphorus? many cars cow pasture solar panels forest.

Answers

Algae blooms are caused by an oversupply of nutrients like to water bodies, causing eutrophication. In the exposed example, a reason for the high levels of phosphorus is option B. Cow pastures.

-------------------------

Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.

The source of these high nutrient levels, especially nitrogen and phosphorus, are anthropogenic activities.

This oversupply favors phytoplankton multiplication, especially cyanobacteria.

Cyanobacteria can grow in seawater, but blooms mainly occur in freshwater where the salinity level is low.

These algae species that affect freshwater bodies are microscopic, photosynthetic organisms.

Blooms of cyanobacteria reflect the sanity state of water and its abiotic characteristics. They cause severe disasters in water biota and affect human health.

This overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.

Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.

These sediments suffer decomposition in the presence of oxygen.

When oxygen disappears, anaerobic bacteria act and produce fermentation.

Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body and humans that get in touch with this water.

Animals die, creating more sediments in the bottom where there are anaerobic conditions.

The lack of oxygen and light continued to increase in decomposition, and fermentation produces a bad smell and toxicity.

Concerning the sources of nutrients that might be causing these events, we can mention, among others, cow pasture.

Cow pasture increases the levels of phosphorous on the ground, which ends in water streams, and from there to ponds or lakes.

Explanation:

Identify two specific populations that most likely increased in number after the mountain lion population decreased. Explain why.

Answers

Any change that occurs at any link of a trophic web will affect the other links. The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.  

----------------------------

The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

The first link corresponds to a producer organism -autotroph-.  

The following links are the consumers -heterotrophs-: herbivores and carnivores.

The last links are the decomposers that degrade organic matter from dead organisms.  

As it is a web, all organisms are equilibrated until a change occurs.

When the change affects any of the involved links, there can be a cascade effect on the web.

A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.

According to the provided trophic web, puma feeds on deer and rabbit.

Since puma was killed, their population size sharply decreased.

This fact followed the predator-prey cycle, in which the predator regulates the prey population size and vice-versa. When there is a decrease in the predator population size, the prey population increases in size because of the absence of their natural predators.

In the absence of puma, deer and rabbits increase their population size. They live in an environment with no predators and enough resources.

The number of individuals of each species increased, and the amount of food consumed increased too.

This change negatively affected grasses and grains, which were over-consumed. Also, crickets and mice were affected too because they compete for the same food source.

So, cascade effects would be as follows,

1) The decreased in the puma population size caused an increase in the deer and rabbit population size.

2) The increase in the deer and rabbit population size caused a decrease in the grains and grasses species population, because they were over consumed.

3) The decrease in grains and grasses caused a decrease in the cricket and mouse population, because they feed on the first ones, competing with deer and  rabbits for food.

The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.

The equator has light closer to 90 degrees, at the poles the angle is lower than 90 degrees. Use this information and refer to the data from Table B to explain why the tropics (near the equator) are hotter than the arctic region (north/south poles). Be sure to include data from Table B in your answer.

Answers

The temperature at tropic region is warmer than the polar temperatures due to angle of the sun.

The tropics which is located near the equator are hotter than the arctic region i.e. north and south poles because the sunlight falls directly on the tropic regions at 90 degrees while on the other hand, the sunlight falls on the poles not directly and form angle lower than 90 degrees.

The amount of solar energy in a given area is greater at the equator and tropic regions than in an equal area at the poles so that's why the temperature at tropic region is warmer than the polar temperatures.
