Answer:
DNA sequencing
Explanation:
DNA sequencing is the method which can be used in order to identify the bacterium that was isolated from the contaminated river. DNA sequencing is the process in which the sequence of nucleotides is determined that is present within a DNA molecule. For identifying the bacterium, the sample of bacteria is collected. After sample collection is completed, genomic DNA is extracted from the bacteria and DNA sequencing will be done of that bacteria.

Discuss in detail to process in which plants produce and use energy
Explanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.
Answer:
Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.
They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.
What is the important function of sweating
Answer:
Sweating helps cool down the body. Water is released through glands in the skin, evaporates off the skin and the body is cooled. During exercise, muscles heat up more, so more sweat is needed.

A female fish may lay thousands of eggs at once. Which additional statement about fish is most useful for explaining how fish species can evolve by natural selection?
A. All of the fish eggs are genetically identical with one another and with the female parent fish.
B. The environment cannot support unlimited growth of the fish population, so only some fish eggs will mature to adults.
C. After the female fish lays a clutch of eggs, neither parent tends to or cares for the eggs or offspring.
D. Fish eggs will develop into embryos only if they are fertilized by sperm from the male fish.
Answer:
D
Explanation:
A can't be the answer since there is something called mutation which means even twins can't be 100% the same
B can't be since it has nothing to do with natural selection
C can't be sine as B, it has nothing to do with natural selection
A female fish may lay thousands of eggs at once. The additional statement about the fish which is most useful for explaining that the fish species can evolve by natural selection is that the fish eggs will develop into embryos only if they are fertilized by the sperm from the male fish. Thus, the correct option is D.
What is Natural selection?Natural selection can be defined as the differential survival and reproduction of the individual species due to the differences in phenotype of the organism. Natural selection is a key mechanism of evolution, the change in the heritable traits or characteristics of a population which take place over the period of several generations.
A female fish may lay thousands of eggs at once.

Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.
What is independent variable?The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.
The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.
The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.

Blackcap birds (Sylvia atricapilla) migrate out of Germany before wintertime. Prior to the 1960s, all members of a particular blackcap population flew to Spain, which had an abundant natural food source. Now, some members of the same blackcap population fly to the United Kingdom, where food placed in feeders by humans is abundant. The blackcaps return to the same forests in Germany to nest during the breeding season.
Some blackcaps that migrate to the United Kingdom have become distinguishable by certain physical and behavioral traits from blackcaps that migrate to Spain. Which of the following best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter?
A- The blackcaps that migrate to Spain will selectively mate with the blackcaps that migrate to the United Kingdom, resulting in increased genetic variation in the blackcap population.
B- The blackcaps that migrate to the United Kingdom will become reproductively isolated from the blackcaps that migrate to Spain, resulting in speciation in the blackcap population.
C- The blackcaps in Spain and the United Kingdom will migrate to other geographical locations in search of potential mating partners, resulting in a smaller blackcap population in Germany.
D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.
Answer:
D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.
Explanation:
By the inhabitants of Spain and the United Kingdom placing feeders out for the blackcaps, the birds in their nesting sites during the winter will have food to eat, meaning a bigger population of the Blackcaps when they return to their main home in Germany.
This best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter.

A population of deer lives in Canada. Over 50 years, the size of the deer
population decreased. What best explains the decrease in the size of the deer
population?
Answer:hunting
Explanation: They can lose population .
Fewer deer were born than died best explains the decrease in the size of the deer population.
What is population?In particular geographical area, when group organism of same particular species inhibit, and they are capable of interbreeding, refers to as population.
This field is important in conservation biology, especially in the development of population survival analyzes that let us predict the long-term likeliness of species remaining in particular habitat parts. Population ecology Although it is a branch of biology, it presents interesting problems for mathematicians and statisticians studying population dynamics.
So, when population size of deer decreased over 50 years, we can say that deer populations are declining due to death, animals leaving the area or dispersal (migration).
Population change = (births + immigration) - (deaths + immigration).

How would this diagram be
different if it showed anaphase I of meiosis instead of anaphase of mitosis?
A Each chromosome would still have two chromatids.
B The chromosomes would look the same as in mitosis.
C You would be able to see DNA in the chromosomes during meiosis.
D Homologous chromosomes would be moving to the same end of the cell
Answer:
This question is incomplete as there is no diagram, however, the question can still be answered without it. the answer is as follows:
A. Each chromosome would still have two chromatids.
Explanation:
The ANAPHASE stage of both mitotic and meiotic division is the stage where chromosomes are pulled apart into opposite poles of the cell. However, meiosis occurs in a two-step division tagged meiosis I and meiosis II.
In mitosis, sister chromatids of a chromosome are separated during anaphase, but in meiosis I, homologous chromosomes are pulled apart during anaphase I. This means that in the anaphase I of meiosis as opposed to anaphase of mitosis, each separated chromosome WOULD STILL HAVE TWO CHROMATIDS.

Answer:
Hibernation helps animals survive the changing seasons. Foods that bears eat, such as berries and flowers, are much less available during cold winter months. When they hibernate, bears enter a deep sleep. ... While they sleep, the bears can survive because their bodies live off of their stored fat or food.
During hibernation, the animal’s body temperature, heart rate and breathing rate all drop to significantly lower levels. Animals do this to survive the winter because the weather is cold and food is scarce. It is advantageous because these animals can quite literally shut themselves off for weeks at a time rather than try and survive through harsh weather conditions.
While many people think bears are hibernators, they actually participate in a similar, though not exact, practice. Instead of hibernating, bears fall into a deep sleep called torpor. During torpor, heart rate and breathing rate decreases, body temperature reduces slightly and bears do not eat or release bodily waste. Bears can sleep more than 100 days without eating, drinking, or passing waste!
Bears sleep in dens that they make themselves, as well as in hollow trees, caves and dens built by other bears. A den can be built in 3–7 days, however, the timing of den building varies from bear to bear. While some bears build their dens months before hibernation season, others choose to excavate their dens.
These animals can dramatically drop their body temperature to below freezing—salty body fluids work to prevent tissue crystallization in particularly cold temperatures.
So really, animals that are true hibernators don’t actually sleep through the entire winter.
The urea produced by their fat metabolism is broken down and the nitrogen is re-used by the bear to rebuild protein.
