Answer:
Natural selection occurs when individuals with certain genotypes are more likely than individuals with other genotypes to survive and reproduce, and thus to pass on their alleles to the next generation.
Explanation:
Based on the graph, it can be concluded that the isotope which is most likely to be found with 6.25% of its original amount in 6 billion years is
Uranium-238
Thorium-235
Potassium-40
Rubidium-87
Potassium is most likely to be found with 6.25% of its original amount in 6 billion years because the half life of Potassium-40 is 1-1.5 billion years in graph. Thus the correct option is C.
If it half in 1 to1.5 billion years = 50% gain
1-1.5 billion years = 25%. gain
If we do that 2 more times we will get 12.5% and then 6.25% gain.
What is half life?
Half life is defined as the time required for half of the atoms of a radioactive substance to become disintegrated.
Our estimate is about 1-1.5 billion years so repeating that about 4 times we get around 4-6 billion years for it to gain 6.25%. From this it can be concluded that Potassium-40 as since it comes the closest to remaining at 6.25% its original amount after approximately 6 billion years.

Answer:
The vast majority of fungi are multicellular. Most of the body of a fungi is made from a network of long, thin filaments called 'hyphae'. Hyphae filaments are made from tubular cells that connect end on end. Each cell is surrounded by a cell wall composed of a compound called 'chitin'.

Like the camel, many animals that live in soft sandy areas have large wide feet compared to their body size. The
large feet are an advantage in these environments because they -
are rapidly toughened by sharp sand grains
distribute body weight over a large area
allow rapid digging in the sand
Dreduce the vibrations caused by walking
Answer:
distribute body weight over a large area
Explanation:
This one's fairly simple. If you have large feet, then your body weight is distributed over a large area (you don't sink as much in sand). If your toes were small, massive body weight would sink the feet into sand.

Answer:
B.
These resources are nonrenewable and will eventually disappear.
Explanation:
Answer:
B. These resources are nonrenewable and will eventually disappear.
Explanation:
Fossil fuels take millions of years to form, but we mine and use them at a rate that is much faster than their replenishment time. That means that, at some point, we will use up all of the available fossil fuels before new ones can be formed.

b. Write a simple word equation to show how NPP is derived from GPP :
The net primary productivity (NPP) and the gross primary productivity (GPP) are related such that: NPP = GPP - Respiration
What is NPP?NPP refers to the net primary productivity of ecosystems. It is the amount of sugar made from photosynthesis when the amount of sugar burned during respiration has been deducted.
The total amount of sugar made during photosynthesis is the Gross Primary Productivity (GPP). This amount does not include the amount of sugar burned by respiration.
Thus, the equation relating the 3 variables would be:

Answer:
False.
Explanation:
Just took the test. Also... It is false because Seafood Watch is not a legal authority and does not have the power to make fishing practices illegal. Seafood Watch is a program run by the Monterey Bay Aquarium that provides recommendations and guidance on sustainable seafood choices based on scientific assessments of fisheries and aquaculture practices. It aims to inform consumers and promote sustainable fishing practices but does not have legal authority to enforce regulations or make fishing practices illegal. That responsibility lies with governmental bodies and regulatory authorities.
