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 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.)

What is the main function of the Krebs cycle?
A. To break glucose down into two pyruvate molecules
OB. To produce carbon dioxide for use in the thylakoid
O C. To produce large numbers of ATP molecules
O D. To provide molecules for the electron transport chain
Answer:
O D. To provide molecules for the electron transport chain
Explanation:
The Krebs cycle, also known as the citric acid cycle, refers to a series of reactions during cellular respiration that produces energy by the oxidation of acetyl-CoA. The Krebs cycle utilizes acetyl-CoA and water in order to reduce the cofactor Nicotinamide adenine dinucleotide (NAD) to NADH, in a process that releases carbon dioxide (CO2). This NADH is then used by the oxidative phosphorylation electron transport pathway in order to generate ATP, the energy coin of the cell.

If the allele for an attached earlobe (e) is recessive to the allele for an unattached earlobe (E), what will be the relative frequency of e in a population?
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.

What is the genotype of the heterozygous black rabbit?
Answer and Explanation:
The genotype would be a Upper case and a lower case letter (depends on what letters you are using).
If you can choose, I would do Bb.
#teamtrees #PAW (Plant And Water)
Answer:
Bb
Explanation:
Heterozygous means different alleles. Since for color, there are, in this situation, 2 alleles, B and b, let's say. B being black dominant, and b being black recessive, or white, let's say. For the rabbit to be black, it needs only one dominant allele. Since the rabbit is heterozygous, the genotype is Bb. I hope I helped, and sorry if this was confusing!
Identify a point source and a non-point source pollutant in your environment. Write a short report discussing these pollutants.
Answer: Point source pollutant: My school is situated near a river. A wastewater treatment plant is a few miles away. The plant uses certain chemicals to treat wastewater, but releases effluents into the river. Although the plant regulates the released effluents, the treatment system gets overloaded during heavy rainfall. As a result, untreated chemicals and wastes enter the river. The plant thus becomes a point source pollutant for the river. The wastes and chemicals entering the river adversely affect growth of plants and fishes in the water body.
Non -point source pollutant: I live in a residential area that has a groundwater reservoir. Last month, the authorities in my area complained that the water in the reservoir was getting polluted. On investigating, they found that rainwater picks up debris and pollutants from roads and sidewalks as it flows on its path. The polluted water enters waterways that are connected to the groundwater reservoir. The debris and pollutants are many in number, and it was difficult to trace exactly where the rainwater picked them up. However, these pollutants affect large areas because the water from the groundwater reservoir reaches many homes. Therefore, the debris and pollutants are non-point source pollutants.
