Archaeologyx(a dinosaur)was found in amber. feathers were visable on the tail a claim
Answers
Archaeology is the study of past human societies and their cultures. However, the term "dinosaur" refers to a group of extinct reptiles that lived millions of years ago.
Nonetheless, if a dinosaur specimen was found in amber, it would be a significant discovery. The claim that feathers were visible on the tail of the dinosaur would also be groundbreaking, as it would suggest that some dinosaurs were feathered, challenging the traditional view of them as scaly reptiles. This discovery would help us better understand the evolution of feathers and their function in dinosaurs.
The fact that the dinosaur was preserved in amber would also provide valuable information about its soft tissue and behavior, offering a unique window into the ancient past. Overall, this discovery would be an exciting breakthrough for the field of paleontology.

Instead of a brown bear, in the taxonomy example in the lesson, let's say we had a giant panda. Which taxa would change? Find out what they would change to and report your findings here.
Answers
A bear belongs to the phylum Chordata (because it has a spine), the class Mammalia (mammals have many distinguishing characteristics, including hair and producing milk for their young), the order Carnivora (will usually eat meat--some bears are exceptions in this category), the family Ursidae (the bear family of animals). The genus and species are the particular type of bear, in this case, let's say it's a brown bear. So our genus would be Ursus, and our species would be arctos. Yes. I think so it's like that.

What is acidity in aquatic system and how is the acidity of water commonly expressed? Why do ecologists typically determine the acidity of aquatic systems? Your environmental consulting firm has been hired by the U. S. National Park Service to assess the environmental quality of a large tract of private land adjacent to Great Smoky Mountains National Park. The Park Service intends to purchase this private tract as part of an effort to expand the park. It is particularly concerned about water quality on this tract because the existing park is widely known for its pristine streams. You visit the tract and begin conducting an on-site assessment of stream water quality. Several important issues arise as you begin this assessment. Please put your knowledge of the properties of water to work in answering the following questions about this assessment
Answers
Answer:
Acidity in aquatic systems refers to the concentration of hydrogen ions (H+) in the water. It is a measure of how acidic or basic the water is. The acidity of water is commonly expressed using the pH scale, which ranges from 0 to 14. A pH value of 7 is considered neutral, while values below 7 indicate acidity, and values above 7 indicate alkalinity.
Ecologists typically determine the acidity of aquatic systems for several reasons. Firstly, the pH of water is an important factor affecting aquatic organisms' survival and reproduction. Different species have different pH tolerance ranges, and extreme acidity can be harmful or lethal to many organisms. By determining the acidity of the water, ecologists can assess the potential impacts on aquatic life.
Secondly, acidity can also affect the chemistry of the water and the availability of nutrients for organisms. Some nutrients become less available at high acidity levels, which can have cascading effects on the entire aquatic ecosystem. Ecologists analyze acidity to understand these nutrient dynamics and how they may influence the health and functioning of the ecosystem.
Assessing the environmental quality of the private land adjacent to the Great Smoky Mountains National Park is crucial because the Park Service intends to purchase it to expand the park. Since the existing park is known for its pristine streams, the Park Service is particularly concerned about water quality on the private tract. By conducting an on-site assessment of stream water quality, you can determine the acidity of the water and evaluate whether it meets the standards of the park's pristine streams. This assessment will help the Park Service make informed decisions about the land purchase and water quality protection in the expanded park.
In summary, acidity in aquatic systems refers to the concentration of hydrogen ions in water, commonly expressed using the pH scale. Ecologists determine the acidity of aquatic systems to understand their effects on aquatic organisms and nutrient availability. Assessing water quality is crucial when considering a land purchase and the protection of pristine streams in national parks.

Answers
Answer: Contact with other cells stop cell growth
Explanation:
Normal cells grown in a petri dish tend to stop growing once they have covered the bottom of the dish because they have reached a state known as contact inhibition. This is a phenomenon where cells stop growing and dividing once they come into contact with other cells and form a confluent layer. This is a mechanism that prevents cells from overgrowing and forming tumors. This process is regulated by contact-dependent signaling pathways, where the cells sense their environment and respond by slowing or stopping their growth and division.

what is the name of semi-permeable membrane which encloses the cytoplasm and all of the cellular organelles?
Answers
The semi-permeable membrane that encloses the cytoplasm and all of the cellular organelles is called the plasma membrane.
The semi-permeable membrane which encloses the cytoplasm and all of the cellular organelles is called the Plasma Membrane. This membrane is made up of two layers of phospholipids, which form a lipid bilayer. The phospholipids have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail, which ensures that the membrane is impermeable to large molecules, such as proteins and sugars. In addition, the membrane contains various proteins and carbohydrates which give it a variety of functions. These proteins act as receptors for molecules, allowing them to move into and out of the cell, and as enzymes that catalyze reactions. Additionally, the carbohydrates on the outer surface of the membrane help to identify the cell and enable it to recognize other cells. The plasma membrane also contains cholesterol, which helps to maintain its fluidity and stability.

Will a sequence of only two bases unambiguously determine the selection of 20 amino acids found in proteins?
Answers
No, a sequence of only two bases cannot unambiguously determine the selection of 20 amino acids found in proteins.
The genetic code is the set of rules that determines how the four-letter nucleotide code in DNA is translated into the 20-letter amino acid code in proteins. The genetic code is a triplet code, meaning that three nucleotides (a codon) code for one amino acid. Since there are 4 possible nucleotides (A, T, C, G), there are 64 possible codons, but only 20 amino acids.
However, if we consider only two nucleotides, there are only 16 possible codons (4x4), which is not enough to represent all 20 amino acids. In fact, several amino acids are represented by more than one codon. For example, the amino acid leucine can be encoded by six different codons (UUA, UUG, CUU, CUC, CUA, and CUG), and the amino acid serine can be encoded by four different codons (UCU, UCC, UCA, and UCG).
Therefore, a sequence of only two bases cannot unambiguously determine the selection of 20 amino acids found in proteins. At least three nucleotides are required to code for one amino acid unambiguously, as the genetic code is a triplet code.

Answers
The researcher who conducted an investigation on a blood disease carried by birds found out that the organism is unicellular and has a nucleus, cell wall, and the ability to produce spores. Based on this information, the organism belongs to the Kingdom Fungi.
The kingdom Fungi consists of unicellular and multicellular organisms that lack chlorophyll and reproduce asexually and sexually by forming spores. They are heterotrophic organisms, which means they depend on other organisms for their food. Fungi cells have a cell wall made up of chitin, which provides strength and rigidity to the cell wall. The cytoplasm of the fungal cells contains many specialized organelles, including nuclei, ribosomes, mitochondria, and Golgi bodies that carry out various metabolic activities.
The researcher's findings suggest that the organism is a unicellular fungus with a nucleus, cell wall, and the ability to produce spores. Spores play a crucial role in the fungal life cycle, as they allow the organism to reproduce and spread to new habitats. These spores can be transported by wind, water, or other organisms to colonize new areas.
In conclusion, based on the researcher's investigation, the organism she isolated from the blood of an infected bird belongs to the Kingdom Fungi.

Answers
Near-equilibrium reaction has a free energy change near zero. Both the forward and reverse reactions' rates in the near-equilibrium reaction are remarkably greater than the flux, but they are virtually comparable.
There isn't much that can be controlled when a reaction is close to equilibrium because it has an equal chance of moving ahead and backward. Large negative variations in free energy indicate that a reaction is far from Near-equilibrium. These responses are essentially unreversible. Two categories of reactions can be distinguished in a metabolic pathway: reactions that are very close to equilibrium (near-equilibrium) and reactions that are far from equilibrium (non-equilibrium).
Energy can transform into other forms. For instance, electrical energy transforms into thermal and light energy when you turn on a lightbulb. Energy change is calculated as the difference between the bond energies of all the bonds in the reactants and the products.
