A) The layer changed from land to water
=> From the fossil of the fish, we can say that the fish used to live in that area From the other fossils, we can tell that land animals lived there first before the fish appear due to the fact that the layer cointaining the bone and tooth is older -> that layer appeared first, which can only mean one thing: that area changed from land to water.
Answer:
A fish fossil found in a rock. A foot bone and tooth are found in an older layer of the same rock. What can scientists learn from a rock?
Explanation:
The area changed from land to water.

Explanation:
A bacterium was found to contain a sequence of ATCGGGATCCT in its genome. A few generations later, the sequence was found to be ATCGGGGGGATCCT. What type of mutation caused this change in the bacteria?
A.
duplication
B.
insertion
C.
inversion
D.
translocation
Answer:
duplication
Explanation:
InversionIf we talk about inversion, it inversion, it is a process in which a specific base sequence is inverted or rearranged in such a way that direction is reversed. For example: ABC is changed into BCA, therefore it is not right option.
TranslocationIf we talk about translocation,it is caused by rearrangement of parts between non homologous chromosomes. It can be balanced or unbalanced but it involves two genes or two sets of chromosomes. But in our example, we have only one sequence of DNA under study, therefore, inversion is not possible.
InsertionTalking about insertion, it involves addition of one or more nucleotide at certain position of gene sequence. There are chances that it can be an insertion of GGG but the insertion of three G instead of any random nucleotide addition or nucleotide sequence addition is rare. So, there are less chances that this is an insertion and more chances that this is an exact duplication event.
Duplication:If we talk about duplication, a certain portion of a gene or chromosome is replicated or duplicated in such a way that it results in more than one copies of that region.
Keeping that definition infront, we see that GGG duplicated to GGGGGG. So, if we logically look at the question, duplication seems to be the most appropriate option.
Hope it help!

duplication

Spider crabs live in the shallow regions of the ocean floor. Algae tend to grow on the surface of spider crabs. The algae provide the crabs protection from predators by camouflaging them. The spider crabs give the algae shelter. What does this description suggest?
1. The algae are parasites of the spider crabs.
2. The algae and the spider crabs have a mutualistic relationship.
3. The spider crabs are commensals, and the algae are parasites.
4. The spider crabs benefit from the algae living on them.
5. The spider crabs are parasites of the algae.
the given description suggests that the algae and spider crabs have a mutualistic relationship that is benefiting each other.
The algae and the spider crabs have a mutualistic relationship.
Option 2
Explanation:A mutualistic relationship is a relationship where two organisms from different species work in cohesion symbiotically and benefit each other by it. Normally, such organisms evolve to accept each other symbiotically because they have been a part of each other’s environment in the later times.
They have adapted to be working together for sustaining their life and becoming beneficiaries for each other in the process and continuing the same for a long period. A basic example of such a relationship is of a bee and a flower.
A box contains 40 number tiles numbered 1 to 40. If a tile is drawn at random, what is the probability that the number drawn is a multiple of 3 or 4? Find P(Multiple of 4 or Multiple of 5)
Explanation 1 P (3 or 4):
There are 40 number tiles numbered 1 to 40.
Multiple of 3 in 1 to 40 are:
There are 10 multiples till 30 (since [tex]3 \times 10 = 30[/tex]) and then 33, 36, and 39 are other three multiples till 40. So there are 13 multiples of 3 from 1 to 40.
Multiples of 4 in 1 to 40 are:
There are 10 multiples till 40 (since [tex]4 \times 10 = 40[/tex]) . So there are 10 multiples of 4 from 1 to 40.
Common Multiples of 3 and 4 in 1 to 40 is,
12, 28, 36, only 3
So, the probability of 3 or 4 is,
[tex]P(\text {mult of 3})+P(\text {mult of 4}) -P(\text {mult of 3 and 4})[/tex]
[tex]=\frac{13}{40} +\frac{10}{40} -\frac{3}{40}[/tex]
[tex]=\frac{23}{40} -\frac{3}{40}[/tex]
[tex]=\frac{20}{40}[/tex]
[tex]=\frac{1}{2}[/tex]
So the probability of 3 or 4 is [tex]\frac{1}{2}[/tex].
Explanation 2 P(4 or 5):
Multiples of 4 in 1 to 40 are:
There are 10 multiples till 40 (since [tex]4 \times 10 = 40[/tex]) . So there are 10 multiples of 4 from 1 to 40.
Multiple of 5 in 1 to 40 are:
There are 8 multiples in 40 (since [tex]5 \times 8 = 40[/tex]). So there are 8 multiples of 5 from 1 to 40.
Common Multiples of 4 and 5 in 1 to 40 is,
20 and 40 only 2
So, the probability of 4 or 5 is,
[tex]P(\text {mult of 4})+P(\text {mult of 5}) -P(\text {mult of 4 and 5})[/tex]
[tex]=\frac{10}{40} +\frac{8}{40} -\frac{2}{40}[/tex]
[tex]=\frac{18}{40} -\frac{2}{40}[/tex]
[tex]=\frac{16}{40}[/tex]
[tex]=\frac{2}{5}[/tex]
So the probability of 4 or 5 is [tex]\frac{2}{5}[/tex].
Compared with the cost of tuition, fees, and books for a traditional college course, the cost of a CLEP exam is:
The answer to the question is: significantly lower
Answer:
much lower.
Explanation:
basically the same answer but it has different wording now
What is the equation of the hyperbola with foci (0, 10), (0, ?10) and vertices (0, 6), (0, ?6)
As given,
Foci (0,10) ; (0,-10) and Vertices (0,6) ; (0,-6)
Now we know the general equation of hyperbola will be,
[tex]\frac{y^{2} }{a^{2} } -\frac{x^{2} }{b^{2} } =1\\\\[/tex]
Now distance from origin to vertex is given, 6 ;
therefore, [tex]a=6[/tex]
And distance from origin to Focus is given , [tex]c=10;\\[/tex]
Using the equation, [tex]c^{2}=a^{2}+b^{2} \\c=10 ; a=6,[/tex]
Apply these values in the equation and find out the value of b,
[tex]c^{2}=a^{2} +b^{2}\\10^{2}=6^{2}+b^{2}\\100=36+b^{2}\\100-36=b^{2}\\ b^{2}=64\\ b=8\\[/tex]
Hence equation of Hyperbola will be,
[tex]\frac{y^{2} }{6^{2} }-\frac{x^{2} }{8^{2} }=1\\\frac{y^{2} }{36}-\frac{x^{2} }{64} =1[/tex]
Here we are done.
Answer:
y^2/36 - x^2/64 = 1

Trey has answered 15 E-mails. This is 20% of E-mails he must answer. How many E-mails does he need to answer? Pls help hkhxdfsrwhetwjeykrutiyuoui;op';kljkthyjrtherweqwertyuilo;p'[o;pio;uiylutryte
easy peasy math (i do math weird in my hea so hopefully i convey this in a way you understand as well)
if 15 is 20% of the total emails he has 80% left right.
20% is 1/5 so you need to find the other 4/5
to do this you take the 1/5 ammount (15) and times that by 4
so thats 15 times 4
which is 60
he has 60 emails left
if the question is how many he has left then the answer is 60
if the answer is how many total emails then you add the 15 hes answered already to the 60 he needs to answer still and its 75
