Scientists today are studying tidal power as an alternative energy source for generating electricity. Some scientists conclude that tidal power is a good alternative source of energy because it uses a natural process, does not rely on fossil fuels, and does not release greenhouse gases. These scientists recommend building tidal power plants around the United States in locations with high tidal power potential. Other scientists conclude that tidal power is not a good alternative energy source because tidal power plants can negatively impact the surrounding ecosystem by killing marine animals, restricting fish migration, reducing the natural flow of water, and causing silt buildup in waterways. These scientists recommend not building tidal power plants in U.S. waterways. Both conclusions are based on valid data and scientific reasoning. How can both conclusions be valid?

Answers

Answer:

See the answer below

Explanation:

Both conclusions can be valid because they are based on valid data and scientific reasoning.

In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.

Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.

Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.

Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.

Knowledge of the driver mutations underlying cancer has led to targeted therapeutics, such as the protein kinase inhibitor imatinib (trade name Gleevec) in cases of chronic myeloid leukemia. Cancer cells often become resistant to a given drug, so researchers continue searching for new drugs that target proteins that contribute to the cancerous phenotype. One recent promising approach uses drugs that lead to ubiquitination and proteasomal degradation of the target protein. Which of the following mutated proteins are good candidates for this approach?
A) oncogenes
B) proteins with loss-of-function mutations
C) proteins with gain-of-function mutations
D) tumor suppressor genes

Answers

Answer:

C) proteins with gain-of-function mutations

Explanation:

Gain-of-function mutations: In biology, the term "gain-of-function mutation" is described as one of the different types of mutation in which the altered or changed "gene product" consists of an entirely new pattern or molecular function associated with gene expression. However, the "gene-of-function mutations" are being always considered as "Semidominant or Dominant".

Most animals cope with this by begin very small and meeding less to eat of by growoing very slow..

Answer:

the answer is They photosynthesize..

Explanation:

In most organisms, the end product of glycolysis is pyruvate. Pyruvate still contains a substantial amount of energy, which can be further extracted. Whether the organisms are operating under aerobic or anaerobic conditions determines the metabolic pathway that pyruvate undergoes to produce more ATP. In this tutorial, you will identify the end products of these metabolic pathways.

Answers

Answer:

Pyruvate helps in the production of ATP.

Explanation:

The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.

You cross a plant with red flowers with a plant with white flowers. Both plants are pure-breeding. All the offspring have pink flowers. What allele relationship does this display? codominance multiple alleles incomplete dominance pleiotropy

Answers

C. Incomplete dominance.

Explanation:

Incomplete dominance is the blending of alleles. If a plant with red flowers and a plant with white flowers produce offspring, then the flowers will be pink. Red and white mixed together will be pink, the alleles blended.

Codominance is where both traits are present, no blending occurs. If a plant with red flowers and a plant with white flowers produce offspring, the flowers will be both white and red. The flower may be white with red spots, or vice versa. Both alleles are present in the flower.

In this case, it is incomplete dominance, as the offspring is a mix of the parents. The alleles blend and the offspring is pink.

Repressorb. Operator c. Promoterd. Corepressore. Inducer

Answers

Answer:

A repressor is a regulatory protein that may bind DNA to inhibit transcription. An operator is a DNA sequence that binds a regulatory protein. A promoter is a DNA sequence that binds RNA polymerase and regulates transcription. A corepressor is a compound that interacts with another protein or compound to form an active repressor. An inducer is a compound that induces or activates transcription, such as lactose.

Explanation:

Repressor proteins bind to DNA and RNA to suppress target gene expression. A DNA repressor blocks transcription by inhibiting the attachment of RNA polymerase to the promoter sequence, while an RNA repressor bind to the mRNA to block translation of the protein. An operator is a DNA sequence required for the attachment of transcription factors. The genes that are transcribed by the binding of a transcription factor to an operator sequence are collectively referred to as an operon. Operons are generally found in prokaryotes but they also can be found in some eukaryotes including Caenorhabditis elegans and Drosophila melanogaster. An inducer is a molecule that activates gene transcription either by binding to repressors/corepressors (thereby inactivating their functions) or by binding activators. For example, the allolactose act as an inducer of the lac operon.

Which of the following statements is compatible with Darwin’s theory of evolution? much of the variation in individuals of a population is heritable resources are unlimited survival depends mostly on luck members of a population are usually very much alike in their characteristics

Answers

Answer:

A. much of the variation in individuals of a population is heritable

Explanation:

Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.

Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
