Which of the following statements about energy producing technologies is true? a. Some currently used energy producing technologies have no disadvantages. b. Alternatives to nonrenewable energy sources can be as effective. c. Air pollution is common to all energy producing technologies. d. Alternatives to nonrenewable energy sources are typically more damaging to the environment. Please select the best answer from the choices provided A B C D
Answer:
b. Alternatives to nonrenewable energy sources can be as effective.
Explanation:
Sources of energy can either be renewable or nonrenewable. Nonrenewable sources of energy e.g petroleum, coal etc are those that are used faster than can be replenished. They tend to release pollution into the environment.
On the other hand, renewable sources of energy has been employed in order to reduce the debilitating effect caused by the nonrenewable sources. Renewable sources of energy, which include solar, wind etc are being technologically used to produce energy. They have proven effective in the sense that they generate energy in an eco-friendly manner. This is the reason they are called Green or clean energy.
Renewable sources are found to be effective and eco-friendly alternatives to the nonrenewable sources.
Answer:
b. Alternatives to nonrenewable energy sources can be as effective.

3) Two students decided to repeat the Hershey and Chase experiment, with modifications for a science competition. They radioactively tag the nitrogen of the DNA, rather than the phosphate. Each nucleotide has only one phosphate and two to five nitrogen atoms, the strategy of labeling the nitrogen atoms would detect a stronger signal than labeling the phosphates. Why won't this approach work
Answer:
Explanation:
In the Hershey and Chase experiment, they aimed to show where the phage DNA went when it exited the protein coat and entered the bacteria. In this scenario, the two student's approach won't work because amino acids (and therefore all proteins) also have nitrogen atoms which ultimately means that the radioactivity would not distinguish between DNA and proteins and the experiment will not provide the correct results.
The second of the two "undeniable facts" is that individuals in a population of any species vary in many heritable traits (traits passed from parents to offspring), so that no two individuals are exactly alike. This fact is important to understanding evolution because it means that
A series of strong storms opened a stream channel between two lakes. The western lake contains a large, diverse population of a species of minnow (these are small fish). The eastern lake has never been populated by fish. When the channel opened, a small group of fish migrated to the eastern lake. Soon after, the stream channel dried up and was never opened again. The fish in the eastern lake thrived and continued to reproduce, building a large population over time. Compared with the fish in the western lake, what characteristics would you expect the population in the eastern lake to exhibit
Answer:
Same characteristics of fishes are present.
Explanation:
Same characteristics of fishes are present in both western and eastern lakes because in eastern lake the present fish species were migrated from the western species so the characteristics of fish population will be same. If the fishes that is present in western lake are small in size so it has same size in eastern lake. Their eating behavior and other characteristic show resemblance with the fishes present in western lake.
In an important experiment, a radioactively labeled bacteriophage was allowed to infect bacteria. In a first trial, the phage contained radioactive DNA, and radioactivity was detected inside the bacteria. Next, phage containing radioactive protein was used, and the radioactivity was not detected inside the bacteria. These experiments led to the conclusion that:_____.
A) DNA is made of nucleotides.
B) genes carry information for making proteins.
C) the genes of this phage were made of DNA.
D) bacteriophages can infect bacteria.
Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.

What will most likely increase if there is a high death rate? immigration emigration birth rate population
Answer:
Emigration
Explanation:
If there is a large number of deaths, then the population would move onto another area to find a mate, more food, and to be together to protect themselves from danger
The component of population that will most likely increase with a high death rate would be emigration.
When the death rate shoots up in a particular environment due to certain factors, organisms are bound to emigrate away from such environment to avoid death from reaching them.
It is a natural instinct of every living organism to respond to stimuli. A high death rate is a stimulus that organisms would want to move away from.

A fine-grained igneous rock forms
Choice B is the right option since the cooling is fast.
The minerals may not have enough room to develop owing to a sudden cooling and therefore their structure is delicate and glassy. The composition of an igneous rock depends on how quickly the magma is cooled when the volcanic eruptions occur. Slow cooling allows big crystals to grow while rapid cooling allows tiny crystals to appear.

16. During the signal transduction process, the signal often triggers a signal transduction cascade. For example, a single activated receptor can activate hundreds of protein A molecules. Each activated protein A molecule activates hundreds of protein B molecules, and so on, until a cellular response occurs. What purpose does this cascade serve
Answer:
The cascade amplifies the signal.
Explanation:
The purpose of the cascade is to transmit a signal to other components in the shortest time possible and do it massively, so when a receptor is activated, this affects a high number of receptors. By doing a cascade reaction, the information travels very fast, achieving the objective quickly, and without a significant loss of energy, in other words, is an efficient method.
Mice living on a granite hillside have coloration ranging from light to dark. The surfaces of the granite rocks are either very dark or very light. Dark mice hiding on dark patches are difficult to see and light mice hiding on light patches are equally camouflaged. Mice with gray fur can be seen everywhere and are preyed upon more heavily. What kind of selection is this?
Answer:
Disruptive selection.
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, predation, etcetera.
In the proposed case, each population of mice is adapted to its environment: one of them is dark-furred as the color of the dark patches it lives on, and the other population is light-furred as it lives in light patches. These adaptations are probably related to survival strategies and help them to avoid predators as they camouflage with the substrate.
Both extreme phenotypes have been favored over intermediate forms, resulting in the development of two groups with very marked differences. Grey-furred mice population belongs to the intermediate phenotype which can be seen everywhere and be preyed upon more heavily. Disruptive selection does not favor this phenotype.
Disruptive selection can lead to speciation, driving to evolution. This is why it is also called "diversifying selection".
