Explanation:

Answer:

A. These homologous structures indicate that these four organisms all share a common ancestor.

Explanation:

Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.

Explanation:

think of a box, if you push it on a smooth floor without friction it would glide pretty easy

but put it on say carpet, the friction from the carpet would not allow the box to move very far

that's also how brakes work, they apply friction to the wheels in order to get them to reduce motion

Answer:

wavelength

Explanation:

the distance between two successive crests or troughs of a wave is called wavelength

The diagram shows the distance between two successive crests or troughs of a wave, and it  is called wavelength.

Typically, wavelength is measured from crest to crest or from trough to trough in transverse waves with points vibrating at right angles to the direction of their advance.

It is measured from compression in longitudinal waves with points vibrating in the same direction as their advance.

It is a property of both traveling waves and standing waves, as well as other spatial wave patterns.

Therefore, It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings.

Answer: C

Explanation: The process that occurred in the lake is natural selection. In the presence of an external environmental influence such as pollution, only the trouts that were fit to survive or in other words those that have the alleles that help in adapting to the new conditions live and increased in numbers. In such a case, one can say the fittest of the organisms survived and the corresponding allelic frequency in that population increased over time. The organisms carrying the other alleles died due to pollution and hence the overall frequency of alleles change.

A lake is home to a large number of trout the trout will suffer from disease is most likely to happen if a chemical is dumped into the lake. The correct option is C.

Chemical pollution is the contamination of our environment with chemicals that are not naturally present.

According to scientific evidence, the trout in option will most likely suffer from disease.

Chemical pollution can harm aquatic life, including fish, by lowering oxygen levels, changing the pH balance of the water, and introducing toxins into their food chain.

Exposure to such chemicals can weaken the fish's immune system, making them more vulnerable to disease.

Option B and A is also less likely to be true because the introduction of chemicals into the water can disrupt the ecosystem's balance and affect the availability of food and oxygen, causing the trout population to decline.

Thus, the correct option is C.

A problem in my life that I have is when I am cooking. When I need to cook something on the stove I use butter on the pan so it won't stick. But getting out that block of butter and trying to cut a perfect slice of butter is always such a freakin hassle. So, a squeezable butter or a butter slicer mechanism that can use would be fantastic.

Or, how about when I use peanut butter. When I use peanut butter for like a PB and J I try to scrape the excess peanut butter back into the jar and whatevers left in the jar but then whats left on the knife is such a pain to wash off. so like a really good scrubber to help wash off peanut butter would be cool.

As the months pass, the table shows that the number of bats also causes an increase in the number of cactus flowers and fruit.

The cactus fruit don't seem to form in large number until the cactus flowers are also going up more in number. This is because pollination is necessary to form the fruit.

Based on this information:

The more bats in the population, the more pollination takes place, and the more cactus fruit is available as a result.

However, if the bats hit carrying capacity, they will be at a population number that is now bad for the number of cactus fruit, since there won't be enough food to feed the population- as more bats eat more fruit, the cactus isn't able to keep up with growing enough fruit to feed the bats at carrying capacity.

Answer: My theory was that they both were created at the same time. So if they both were created at the same time, then I guess that would solve this whole infinite loop thing. If the chicken came first, then it had to have come from an egg. So that means if the egg came first, where did that egg come from? A chicken. So its just a whole infinite loop. So thats what I think.
