Explanation:
info gathered b4 and after an experiment is used to confirm or disprove a hypothesis ( educated guess).
The diagram below illustrates a natural Earth process through which the atmosphere
traps heat. Many scientists hypothesize that human activities are accelerating this
process, resulting in a global warming trend. What human activity is believed to have an
adverse effect on the natural process pictured here?
Answer: c. burning of fossil fuels.
Explanation:
Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.
One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

Discuss how algae help support other life on earth?
Answer:
In the distant past, algae helped turn the earth's then inhospitable atmosphere into one that could support modern life through photosynthesis, which plants use to turn carbon dioxide and sunlight into sugars and oxygen. Some of the algae sank to sea or lake beds and slowly became oil.
Snow owls prey on lemmings in their arctic habitat, and their survival is closely linked to the abundance of lemmings. In years when there are many lemmings, snowy owls may raise a dozen babies. How might a scarcity of lemmings affect the snowy owl population?
As you mentioned, the snow owls are linked with the lemmings. This is true of any predator-prey population model. If there aren't many lemmings (prey), then the owl population will go down. This is due to lack of food. The unlucky members will starve and die off. As the predator owl population decreases, the lemming population will go back up. This is because the lemmings aren't being eaten by the predators (as there are less owls to be eating the lemmings). Then as the lemming population goes up, so does the owl population.
As one population goes up, the other does too. This is until they reach the carrying capacity and the populations go down. This cycle repeats itself. It's quite common to find populations in flux all the time like this. Keep in mind that we're only focused on the food aspect and not other factors such as habitat. If the lemming habitat is severely compromised, then that will also affect the lemming population. To keep things relatively simple, we'll assume the habitat stays constant.
Side note: The common misconception is that lemmings jump off cliffs on purpose, and kill themselves, but this is a myth that was unfortunately spread around. Lemmings do not do this. If they did, then the species would have died off long ago.
What is the MOST recent evidence supporting plate tectonics?
A) GPS monitoring of plate speeds and movements
B) the WWI discovery of paleomagnetic reversals
C) the 1963 mapping of the tectonic plate boundaries
D)C-14 dating of marine fossils found in the himalayas
A.) GPS monitoring of plate speeds and movements.
I know this is correct because it is constantly paying attention to what is going on with the tectonic plate, monitoring their movement every day, making it the most recent.
Hope this helps and have a nice day.

A. Humans were only related to
chimpanzees, but not other animals
B. The first species appeared on Earth
about six million years ago
C. Each species was unchanged since the
moment of its creation.
D. All of the above
Answer:C each species was unchanged since the moment of its creation
Explanation:
people believed we were all the same and we just were there on the earth
Before Darwin's theory of evolution people believed that : ( C ) Each species was unchanged since the moment of its creation
Before Darwin proposed the theory of evolution most people believed that the species of plants and animals on earth were not connected to each other and could not have evolved from each other. because they believed that human species were outside the earth given that the earth was perceived as been too young.
Darwin's theory of evolution proposes that species evolve ( change in physical attributes ) over time through the process of natural selection. Darwin believed that man evolved from Apes over million of years.
Hence we can conclude that Before Darwin's theory of evolution people believed that : Each species was unchanged since the moment of its creation.

Answer:
D and C (glucose and oxygen gas)
Explanation:
I took the test
The product of photosynthesis are option (C) glucose and (D) oxygen gas.
What is photosynthesis?The energy from light is converted into the form of chemical energy through a process known as photosynthesis, which is utilized by living creatures like plants. Through a process known as cellular respiration, this chemical energy can eventually be converted into usable fuel that can be utilized to power the activities of the organism.
It is standard practice to write the equation that describes the process of photosynthesis as follows: 6CO2 + 6H2O gives C6H12O6 + 6O2.
This suggests that chlorophyll, which takes in light energy and converts it into chemical energy, is responsible for the transformation of the reactants, which are comprised of six molecules of carbon dioxide and six molecules of water, into the products, which are one molecule of sugar and six molecules of oxygen.

The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

According to the National Institute of Health, atrial fibrillation (A-F) occurs if rapid, disorganized electrical signals causing the heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In A-F, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. Based on the passage above, how will atrial fibrillation affect blood pressure?
A. It will lower blood pressure because less blood is pumped per beat.
B. It will increase blood pressure because the heart is contracting faster.
C. It will increase blood pressure because the atria fill fully with blood.
D. It will lower blood pressure because blood volume drops in the atria.
Answer:
A. It will lower blood pressure because less blood is pumped per beat.
Explanation:
I thought B might be a potential answer, but since the atria are not filling properly and heart rate is increased, it would make sense that blood pressure drops (effect of faster heart contraction is negated by the drop in blood volume in the atria).

Which of the following statements about human society and limiting factors is true?
a. Modifications made to the environment to reduce the impact of limiting factors can cause
disruption to the natural balance of an ecosystem.
b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.
