Discuss the challenges trying to do work in the field and how unanticipated problems occur in science and methods may need to be changed. For example, how did the crew change their method for getting close to the sharks? Why did they have to change their approach?
plz answer thissss
Also, my real name is Savannah ^w^
Answer: Correct approach is required to be taken for conducting the research.
Explanation:
The scientific methodology involves the observation, experimentation, deduction of the conclusion. Moreover, similar studies in the same field also add up to the literature and change in the methodology for a particular discipline of study to understand the scientific phenomena better. The unanticipated problems may include the physical, psychological, and economic harm to the subjects.
But according to the given situation the crew might have not taken protection while conducting research in the shark surrounding. Shark is a carnivore and can cause massive harm to the navigators so precautions are required to be taken to protect themselves and conduct research.
In order for protein synthesis to occur, both transcription and translation must occur. Which of the following statements describes the difference between transcription and translation?
In transcription, the genetic code of a DNA molecule is encoded. Translation is the process of converting the DNA code into a code that RNA can use.
In transcription, an amino acid chain is encoded in a DNA molecule. Translation is the process of turning the amino acids into nucleic acids in an RNA molecule.
In transcription, a double helix DNA molecule is split into two separate single strands. Translation is the process of joining each single DNA strand with a single strand of matching RNA.
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. Translation is the process of creating an amino acid chain using the encoded messenger RNA.
Answer:
1
Explanation:
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. The translation is the process of creating an amino acid chain by using the encoded messenger RNA. So the correct option is D.
What are transcription and translation?The first step in the process of gene expression is called transcription. In this process, the DNA sequence of a gene is copied for the formation of an RNA molecule.
RNA polymerase enzymes link the nucleotides of DNA to form an RNA strand. The DNA strand is the template. For every gene in the genome, transcription is separately controlled.
The translation is the process by which an mRNA molecule encodes for a protein. The process of translation happens with the help of tRNA in the ribosomes.
Translation requires ATP which is produced by the tRNA. The tRNA in the ribosomes supplies energy to RNA for the transcription of proteins The entry of mRNA occurs by the smaller subunit of RNA and the amino acid chain extends from the larger subunit.
Therefore the correct option is D.

loss of biodiversity is not among the three major categories of environmental problems.
What are environmental problems?Environmental problems are the results of human activities on the biophysical environment, most frequently negative consequences that lead to the degradation of the ecosystem.
They are negative impacts of human activities on the environment. These include environmental issues including pollution, population growth, waste management, and the greenhouse effect, among others.
To achieve a balance between man and the environment, many environmental protection measures are being implemented at the individual, organizational, and governmental levels. Making use of reusable items instead of disposal ones is one of the solutions to environmental issues.

how do the reactant molecules become the molecules found in the products... what happens to them
Explanation:
Molecules of reactants and products undergoes chemical changes when they combine.
The combination leads to the breaking of bonds and rearrangement and this brings about the formation of new products.
Atoms in molecules tends towards stabilityThey often want to mimic the noble gases and would keep rearranging until stability is attained. This leads to the formation of new compounds in the product end of the reaction.If the world’s population keeps on growing, what might some consequences be for planet Earth? Name at least 3.
Answer:
Effect on climate change.
Resource deplition.
Global warming.
Air polution.
Water contamination.
Explanation:
Humans are known for being too lazy to throw their trash in an actual trash can, thus leading to water contamination from people throwing trash in the water. Air polution tends to come from nuclear factories and gas powered cars. Resource deplition, like mass tree cutting for building buildings.

Explanation:
Cells have lots of membranes, which gives them a high amount of?
Answer:The plasma membrane
Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
A phospholipid is made up of a hydrophilic, water-loving, phosphate head, along with two hydrophobic, water-fearing, fatty acid tails. Phospholipids spontaneously arrange themselves in a double-layered structure with their hydrophobic tails pointing inward and their hydrophilic heads facing outward. This energetically favorable two-layer structure, called a phospholipid bilayer, is found in many biological membranes. [Close-up of a phospholipid]
As shown below, proteins are also an important component of the plasma membrane. Some of them pass all the way through the membrane, serving as channels or signal receptors, while others are just attached at the edge. Different types of lipids, such as cholesterol, may also be found in the cell membrane and affect its fluidity.
An image of plasma membrane shows the phospholipid bilayer, embedded proteins, and cholesterol molecules. The membrane separates the extracellular space, outside of the cell, from the cytosol inside the cell.

The plasma membrane is the border between the interior and exterior of a cell. As such, it controls passage of various molecules—including sugars, amino acids, ions, and water—into and out of the cell. How easily these molecules can cross the membrane depends on their size and polarity. Some small, nonpolar molecules, such as oxygen, can pass directly through the phospholipid portion of the membrane. Larger and more polar, hydrophilic, molecules, such as amino acids, must instead cross the membrane by way of protein channels, a process that is often regulated by the cell. You can learn more about cellular transport in the membranes and transport section.
The surface area of the plasma membrane limits the exchange of materials between a cell and its environment. Some cells are specialized in the exchange of wastes or nutrients and have modifications to increase the area of the plasma membrane. For instance, the membranes of some nutrient-absorbing cells are folded into fingerlike projections called microvilli, singular, microvillus. Cells with microvilli cover the inside surface of the small intestine, the organ that absorbs nutrients from digested food. The microvilli help intestinal cells maximize their absorption of nutrients from food by increasing plasma membrane surface area. [Microvilli and celiac disease]

The cytoplasm
The part of the cell referred to as cytoplasm is slightly different in eukaryotes and prokaryotes. In eukaryotic cells, which have a nucleus, the cytoplasm is everything between the plasma membrane and the nuclear envelope. In prokaryotes, which lack a nucleus, cytoplasm simply means everything found inside the plasma membrane.
One major component of the cytoplasm in both prokaryotes and eukaryotes is the gel-like cytosol, a water-based solution that contains ions, small molecules, and macromolecules. In eukaryotes, the cytoplasm also includes membrane-bound organelles, which are suspended in the cytosol. The cytoskeleton, a network of fibers that supports the cell and gives it shape, is also part of the cytoplasm and helps to organize cellular components.
Even though the cytosol is mostly water, it has a semi-solid, Jello-like consistency because of the many proteins suspended in it. The cytosol contains a rich broth of macromolecules and smaller organic molecules, including glucose and other simple sugars, polysaccharides, amino acids, nucleic acids, and fatty acids. Ions of sodium, potassium, calcium, and other elements are also found in the cytosol. Many metabolic reactions, including protein synthesis, take place in this part of the cell.
