A sample of Potassium-40 has a mass of 2020 grams.
Potassium-40 has a half life of 1.3 b.y. How much Potassium-40 and Argon 40 would there be after 5.2 b.y.
Answers
The idea here is that the ratio that exists between the number of atoms of argon-40 and the number of atoms of potassium-40 will give you the number of half-lives that passed.
As you know, the half-life of a radioactive nuclide tells you the time needed for half of the atoms of said nuclide to undergo radioactive decay.
In your case, you know that potassium-40 has a half-life of
1.25
billion years because that's how long it takes for half of the number of atoms present in the sample to decay to argon-40.
Now, let's say that your sample started with
A
K-40
atoms of potassium-40 and
0
atoms of argon-40.
You can thus say that the sample will contain--keep in mind that the atoms of potassium that decay form argon-40!
After

At this point, we can use this pattern to say that after

−
A
K-40

Now, you know that sample contains

you can say that

=

⇒
n
=

This means that
5
half lives must pass in order for the sample to contain
31
atoms of argon-40 for every
1
atom of potassium-40.
Consequently, you can say that the age of the rock is
5
half-lives
⋅
1.25 billion years

=

−−−−−−−−−−−−−−−
I'll leave the answer rounded to three sig figs, but keep in mind that you have two significant figures for the number of atoms of argon-40 present per atom of potassium-40.

O parasitism
O Competition
O Predation
O Commensalism
O Mutualism
Answers
Answer:
Mutualism
Explanation:
Both plants don't fight over the spot and are in within the same place.
Grass and Dandelions both compete for nutrients and water belongs to the same species, competition occurs between the same species called interspecific competition, hence option b is correct.
What is the interaction between Grass and Dandelions?When two distinct species fight for a restricted resource, such as space, this is known as interspecific competition. Grass, dandelions, and a variety of other plants compete for nutrients and water on a lawn.
Competition happens among individuals of the same species as well. The deep taproot draws minerals from the earth, such as calcium, and makes them available to other plants. While most think of dandelions as lawn killers, they really enrich the grass.
It will attach itself to sharks and other large fish in order to get a ride underwater. This is an example of commensalism but this connection can evolve into mutualism when the remora feeds.
Therefore belongs to the same species kind of interspecific relation, Grass and Dandelions having the interaction of competition, hence option b is correct.

Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process.
Nutrients for a number of metabolic processes are basic compounds and macromolecules available. Through processing organic matter such as lipids, fats and proteins, animals get energy in heterotrophic nutrition.

How might retaining too much heat be a disadvantage to an organism?
Answers
Answer:
Too much heat can disrupt subcellular structures such as membrane proteins, and enzymes while damaging the integrity of the plasma membrane.
Explanation:
Proteins are macromolecules made up of amino acids. These fold and bond to form several biologically important molecules. For instance, enzymes, a special type of protein functions by providing alternative reaction pathways. They work best at a specific pH and optimal temperature range, beyond which they become non-functional or denatured entirely.
The denaturing of proteins occur at high temperatures, and alter protein folding, bonding and other types of behavior. Furthermore, membrane proteins are important for regulating cell function. If these are disrupted, the system cannot maintain homeostasis i.e a constant internal environment.
