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?
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.
After buying a new house by the lake, a family wanted a better view of the water so they could watch the sailboats. They hired a company to cut down the small trees and shrubs that were blocking the view.
Which type of water pollution is most likely
1 . Nutrient
2.sediment
3.toxic
4. Bacterial
The water pollution that is most likely to occur is Nutrient pollution
Pollution can be defined as the addition of materials or energy (pollutants) to the environment that damages it, making it undesirable or unfit for life. There are different types of pollution which includes:
--> Air pollution
--> Radiation pollution
--> soil pollution and
--> water pollution.
WATER POLLUTION is defined as the type of pollution that occurs when pollutants are being released into water bodies such as streams, lakes, ocean, beaches making it unsafe to use for both human and aquatic life activities. Depending on the type of pollutants, there are also different types of water pollution, these include:
chemical pollution Groundwater pollutionsediment pollutionmicrobiological pollutionnutrient pollutionsurface water pollution and Oxygen-depletion pollution.NUTRIENT pollution occurs when there is EXCESS of it in the water bodies through organic fertilizer or compost manure from the leaves of the cut down trees and shrubs. When nitrates from the agricultural waste gets into the water body(lake) it can cause a drastic increase in aquatic plant growth, especially algal growth. This excessive growth can lead to a decrease in oxygen level of water they by affecting the aquatic life of the lake.
Therefore the CORRECT OPTION is A Nutrient pollution.
Option B is wrong because sediment pollution is a type that involves loose sand, clay, silt, and other soil particles that are carried from a site by runoff water not from cut down trees.
Option C is wrong because toxic or chemical pollution is caused by chemicals from industrial wastes.
Option D is wrong because it is caused by natural existing bacteria in the water bodies and are capable of causing disease when ingested. Example Vibro cholera bacteria.

Galactosemia is a metabolic disorder characterized by the inability to metabolize the sugar galactose. People with galactosemia suffer from liver, kidney, and brain damage among other symptoms. A gene mutation underlying galactosemia was identified by sequencing the genome of a person with galactosemia. What additional evidence would support the hypothesis that the mutation in the candidate gene causes the disease
Answer:
Genetic mapping for unequivocal identification of the potentially causative mutation
Explanation:
Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.

Answer:
A cell biologist examines a diploid cell from a barley plant during prometaphase of mitosis and determines that 28 chromatids are present. The role of meiosis in this plant is to reduce the number of chromosomes per cell from 14 to 7.
Explanation:
Meiosis is a process that happens in two different phases, and there are many more steps in every phase. This procedure reduces the number from diploid to haploid, that's why the number of chromosomes per cell reduces from 14 to 7. Thanks to this process we have diversity in every organism that has sexual reproduction.

Answer:
The level of specialization is given by the function.
The function of the organ makes the cell as it becomes mature, its more specific function becomes.
First, a stem cell differentiates itself into a hepatic or neuronal cell, thus generating that its functions are limited compared to the rest of the stem cells.
After this process, throughout the cell development and maturation of the organ, its cells become more specific in a single activity.
Explanation:
The differentiation of the stem cells is regulated by the genetic code, the migration of these during the embryonic stage of the mouse and the external stimulation that these stem cells perceive.

Transcriptional regulation of operon gene expression involves the interaction of molecules with one another and of regulatory molecules with segments of DNA. In this context, define and give an example of each of the following:
a. operator
b. repressor
c. inducer
d. corepressor
e. promoter
f. positive regulation
g. allostery
h. negative regulation
i. attenuation
Answer and explanation:
The operator is a DNA fragment localized between the promoter and structural gene sequences that are able to repress operon transcription. A repressor is a molecule that binds to the operator to inhibit transcription, while an inducer is a molecule that activates transcription by binding either to the repressors or to the activators. A corepressor is a molecule that binds to repressors in order to activate them. A promoter is a DNA sequence localized upstream structural genes which binds to a transcription factor in order to activate operon transcription. Positive regulation is the process by which operon transcription acts as a positive loop, thereby increasing its own transcription, while negative regulation is the process by which operon transcription inhibits its own expression. Allostery refers to the process by which a molecule regulates operon transcription by binding to distal (and therefore non-functional) sites of the operon. Attenuation is a process able to reduce operon transcription and also to block subsequent translation.
