How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.

Which of the following would be considered a source of error in an experiment
Answer:
The answer is laboratory mice are similar but not identical to each other.
Populations can have variety, despite being made up of
the same species. If a population has different expressed
traits, this can be due to different inherited alleles. The
frogs below are the same species, but they have different
shades of green based on their inherited alleles. In a
particular environment, lighter green frogs are easier to see
by predators. Explain how natural selection could lead to a
change in allele frequency.
Answer:
The lighter frogs will be eaten and will not be able to reproduce offspring with the light green trait. Darker green frogs will be able to reproduce more dark green frogs. Eventually most/all frogs will be a darker green because they carry a trait that improves chances of survival.

They repel one another. I think
Answer:
When two forces act in the same direction a few things can happen such as...
Explanation:
If the two forces are equal then there will be no movement but it the two forces are different, one being stronger the the strong one will over power the weaker one and the motion will move against it the weaker one causing it to move in the direction of the stronger, and of course there will be a bit of resistance.

Which statement is true regarding meiosis in cells?
O In anaphase I, sister chromatids are pulled apart at the centromere.
O In prophase II, homologous chromosomes are paired up in a tetrad.
O The daughter cells do not undergo cytokinesis at the end of meiosis
The products of telophase I are two haploid daughter cells..
answer : the last one is true, yeah !!
d :: the products of telophase 1 are two haploid daughter cells ..
Chromosomes finish migrating to opposing ends of the cell in telophase I. Cytokinesis then creates two daughter cells. Therefore,option (D) is correct.
What happens is telophase I?The parent cell has two poles at Telophase I of the meiotic cycle, each with a full complement of haploid chromosomes (which still have their sister chromatids). Now, a cleavage furrow forms, separating the cytoplasm of the cell in two (a proccess ultimately called cytokinesis).
The homologous chromosomes divide into distinct nuclei during telophase I. The cell restores its nuclear membrane, deconstructs the microtubules and spindle fibers, and then initiates cytokinesis. After then, the cell enters a phase of rest known as interkinesis.

Imagine customers moving into and out of a coffee shop. Which situation
resembles how a reaction in dynamic equilibrium acts?
A. There are the same number of people inside the coffee shop as
outside it.
B. People enter the coffee shop at the same rate as others leave.
C. No people are moving either into or out of the coffee shop.
D. Some people sit down and drink their coffee slowly, while others
drink theirs quickly while standing up.
No
Answer:
B. People enter the coffee shop at the same rate as others leave.
Explanation:
did the test !!
The answer is B. People enter the coffee shop at the same rate as others leave.
In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.
Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.

What would happen if cytokinesis did not work properly?
1) DNA replication would not occur
2) A cell would have a nucleus with too many chromosomes
3) A cell would have two nuclei
4) New daughter cells would not have enough organelles or would be missing organelles
5) a cell would be smaller in size
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells

During cellular respiration, glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?
chemical energy originally stored in the glucose molecule
potential energy from the difference in the concentration gradients of the cell
kinetic energy generated by the chemical reactions
electric current created during the destruction of electrons in the glucose
Answer:
1.Sugar bonds
2.Transport proteins
3. Digestion
4. Oxidation
explanation
Chemical energy is stored in the bonds of sugar.
The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.
Digestion converts chemical energy into kinetic energy used by cells.
When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.

Which statement BEST describes the measurements he would find in the jar, in the experiment group, B, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
The provided question is incomplete as the important part and group of choices was missing, however, the correct question is given below:
In an experiment, Tony placed a potted plant under a bell jar, completely sealing the jar to the tabletop. After placing a box over the bell jar for 24 hours, he measured the concentrations of oxygen and carbon dioxide in the gas in the jar. Which statement best describes the measurements he would find in the jar, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
Concentrations of both carbon dioxide and oxygen decreased.
Concentrations of both carbon dioxide and oxygen increased.
Carbon dioxide concentration increased; oxygen concentration decreased.
Oxygen concentration increased; carbon dioxide concentration decreased.
Answer:
The correct answer would be - Carbon dioxide concentration increased; oxygen concentration decreased.
Explanation:
There are two major processes respiration and photosynthesis that help in the production and utilizing the carbon dioxide and oxygen in plants. In order for your plant to grow photosynthesis is the process that converts carbon dioxide into glucose and oxygen. Photosynthesis only occurs in the daylight process so the use of carbon dioxide and producing oxygen is limited.
On the other hand, respiration is a continuous process that uses oxygen and glucose to produce carbon dioxide therefore the correct answer is Carbon dioxide concentration increased; oxygen concentration decreased

a. It could be more or less frequent than T.
b. It could only be equally as frequent as T.
c. It could only be more frequent that E.
d. It could only be less frequent than T.
Answer:
It could be more or less frequent than T.
Explanation:
As demonstrated by the Hardy-Weinberg principle, the dominance or recessiveness of an allele does not determine its frequency in a population.
In the given scenario, the relative frequency of e in a population will be It could be more or less frequent than T. The correct option is a.
What is allele?An allele is one of two or more DNA sequence versions at a given genomic location. For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent.
The Hardy-Weinberg principle demonstrates that an allele's dominance or recessiveness does not determine its frequency in a population.
Thus, the correct option is a.

Which statement describes natural selection
Answer: You didn't put any statements lol
Explanation:
But basically natural selection is when organisms with the most favorable traits will survive and reproduce. (ex. there are 2 strains of bacteria - one that resists antibiotics and one that doesn't. The one that resists the antibiotics will strive and reproduce because that will be the more favorable trait that will be able to be inherited by future generations.)
