Explanation:
Petrified fossils form when minerals replace the structure of an organism. This process, called permineralization, occurs when groundwater solutions saturate the remains of buried plants or animals. As the water evaporates the minerals remain, eventually filling in the spaces left as the organism slowly decays.
Describe the importance of Tiktaalik roseae to the study of evolution.
Answer:The discovery of well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins.
Explanation:can i have brainless?
Tiktaalik roseae was famous for his discovery of well-preserved pelves and a partial pelvic fin in aquatic organisms. These structures support aquatic organisms to a large extent.
What is Evolution?Evolution may be defined as a methodology through which gradual changes in organisms may take place over many generations. Due to this, a species of animals, plants, or insects slowly change some of their physical characteristics and adapt to nature.
According to the context of this question, it was the time of about 3.75 million years ago, when the transition between fish and first-legged animals was observed. This observation clearly demonstrates that the evolution of hind legs in the animals was actually initiated through the hind fins of the fish.
Therefore, the importance of Tiktaalik roseae to the study of evolution is understood by the fact of describing well-preserved pelves and a partial pelvic fin in aquatic organisms.

A. Allopatric speciation
B. Sympatric speciation
C. Parasympathetic speciation
Certain individual females in a population of deer decide to stop breeding with males that don't have antlers. This is an example of which Form of speciation A. Allopatric speciation.
What's an allopatric speciation instance?
Allopatric speciation occurs when two companies of organisms are separated by using a bodily or geographic barrier. Not unusual examples of those boundaries include mountain degrees, oceans, or even big rivers. The isthmus of Panama is a high instance of a geographical barrier and it separates the Atlantic and Pacific oceans.
In allopatric speciation, groups from an ancestral populace evolve into separate species due to a period of geographical separation. In sympatric speciation, agencies from the same ancestral populace evolve into separate species with no geographical separation.
Allopatry, which means 'in another area', describes a population or species this is bodily remoted from different comparable companies by an extrinsic barrier to dispersal. From a biogeographic angle, allopatric species or populations are those that do not have overlapping geographic levels.

Choose the items that complete the sentence about the key features of f(x) = 8x. The y-intercept is Choose... , the asymptote is y = Choose... , and the range is y > Choose... .
Answer:
I suppose that the equation is:
f(x) = 8/x
(You wrote 8x, this is a linear function, so it has no asymptotes, then I assume that the actual function was 8/x)
The y-intercept is the value such that f(x) = 0
Notice that there is no value of x such that 8/x = 0 (if the numerator is never zero, then the quotient can't be zero)
So we do not have an y-intercept.
The asymptote:
Here we have four:
if x tends to zero from the negative side, then:
8/x tends to negative infinity.
if x tends to zero from the positive side, then:
8/x tends to positive infinity.
These two asymptotes can be written as:
[tex]\lim_{n \to \_-0} \frac{8}{x} = -\infty\\ \lim_{n \to \_+0} \frac{8}{x} = +\infty[/tex]
We also have two when x tends to plus infinity (and 8/x goes to zero) and when x tends to negative infinity, such that the function tends to zero again, these two can be written as:
[tex]\lim_{n \to \infty} \frac{8}{x} = 0\\ \lim_{n \to -\infty} \frac{8}{x} = 0[/tex]
Finally, the range:
The only value that y never reaches (only on limits) is:
y = 0
Then the range is the set of all real numbers except the zero, or:
R : { x ∈ R / {0} }
The diagram below represents some changes that took place in a bacterial population recently exposed to an antibiotic.Which statement would best explain the presence of bacteria on day 4?A) A bacterial population cannot survive exposure to antibiotics.B) This bacterial population cannot survive exposure to this antibiotic.C) Bacteria can change whenever it is necessary to survive antibiotic treatment.D) Some of the bacterial population was resistant to this antibiotic.
About the question:
You will find the diagram used to answer the question in the attached files.
Answer:
D) Some of the bacterial population was resistant to this antibiotic.
Explanation:
The term resistance refers to an inheritable change in a population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach a desired effect on the target population.
The excessive use of antibiotics on the bacteria population leads to the fixation of new mutated genes -by natural selection-. The mutated genes make these cells even more resistant to the drug.
In the exposed example we have,
Day 1 ⇒ a big population of white bacteria and only one black cell, probably carrying mutated genetic material.The population was treated with antibiotics.
Day 2 ⇒ there are fewer white bacteria and three black cells. This means that white bacteria are dying, while the black ones are reproducing.The mutated phenotype gets to survive under the effects of the chemical.
Day 3 ⇒ There are no more white bacteria. Only the black population survived and keeps reproducing.The mutated bacteria reproduce with the capability of tolerating the antibiotic dose that is usually used to destroy a population of white bacteria.
Day 4 ⇒ Black bacteria got to survive a produce a big population. Remember that bacteria follow the exponential growth model, meaning that their reproductive rate is too high. This black population survived the antibiotic action and reproduced at high rates.Use the table to write the phenotypes that would be visible given the different genotypes.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.

1Which waste needs to be sorted and which can be disposed of in the general bin? 2How do you know which wastes can be recycled and sorted? 3Provide arguments to show that we save energy by making items from recycled materials.
Answer:
Waste which needs to be sorted are: Plastic, paper, and alminium. And the ones can be disposed can be any other items such as food, sweet wrappers, plastic wrapping, and broken glass.
The waste bags are opened and the waste is put onto a conveyor belt and moved into a processing area. First, the waste will go into a pre-sort area, where any items that can't be recycled are removed, and then the materials move into an area where they can be sorted automatically by machines, or manually by workers.
As most people know, recycling can reduce pollution, animal harm, and energy because we won't need as much material to be making the same thing over and over again so in general, recycling is the best way to save energy and for the sake of the planets environment.

Relate the importance of classifying to a real-life situation you encountered personally.
State that situation here. What have you learned from that situation
The correct answer to this open question is the following.
The real-life situation I encountered personally was to stereotype people according to the way they looked.
Unfortunately, I stereotype and prejudge people just because of their nationality. And I was so wrong.
Since I was a kid I have heard that immigrant people were not good. That they had a different way of thinking, different culture, and traditions that were not good for the American people.
So when I met this kind of people in school, I was on the defensive side. I was never rude to anyone, just put my "barriers" in front of me and tried to keep my distance.
However, one day during finals, I encounter some problems due to personal issues. I ask help from my friends, all American friends, and they never answered. To my surprise, these people from abroad were there for me and lent me a helping hand when I needed it the most. They treated me well as if I were one of them.
What I learned from that situation was that you never have to judge or stereotype people just because they are not like you. You always have to be open to know different kinds of people and welcome different ideas and cultures to learn more about people.
I promise to never judge people because I do not want other people to judge me without really knowing me.
