what would have to occur in order for a scientist to recognize the findings of another scientist

Answer:

Nonsense mutation. A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.Sep 21, 2020

Explanation:

The red panda faces several challenges due to climate change and human intervention in its habitat. One of the primary issues is that the red panda's natural habitat is being destroyed as a result of deforestation, agriculture, and other human activities.

This puts the species at risk of losing its primary food source, bamboo, which is also threatened by climate change. In addition to habitat loss, the red panda may also face challenges due to changes in temperature and precipitation patterns caused by climate change.

This could affect the distribution and abundance of bamboo, which could in turn impact the red panda's ability to survive. In some areas, the red panda may also face competition with other species that are expanding their ranges as a result of climate change.

Overall, the red panda faces significant challenges due to climate change and human activities, and will need to adapt in order to survive in the face of these threats. Conservation efforts, including habitat protection and restoration, may be critical for the long-term survival of this species

An ecosystem is distinct from other systems because it includes both living and non-living elements that interact with one another in intricate ways. Any changes to one element can have an impact on the entire ecosystem.

Ecosystems can differ in almost every conceivable biotic or abiotic trait, in addition to size. There are ecosystems that are marine, freshwater, and terrestrial (found on land).

An ecosystem is made up of a number of components, including flora, microorganisms, animals, and the overall environment. The majority of ecosystems can adapt to and change along with changes in the surrounding environment and feature well-defined soil, climate, plant, and fauna (or communities).

Sugar from carbohydrates provide the body with quick energy. Lysosomes help to build and digest molecules in the body. Lipids store energy long term, provide insulation, and cushion organs.

The function of DNA and RNA is to carry genetic information. They are both involved in protein synthesis. DNA encode the amino acid residues sequence in a protein by the use of genetic code. The cells will make a copy of DNA in the RNA to be able to read the genetic code.

Answer - a. Store and transmit hereditary information

The two correct statements that relate RNA, amino acids, and proteins are C and D.

RNA is used to build the amino acid sequence: RNA molecules, specifically messenger RNA (mRNA), serve as templates for protein synthesis. During a process called translation, the sequence of nucleotides in mRNA is read by ribosomes, and the corresponding amino acids are assembled in a specific order to form a protein.

Long amino acid sequences fold in a specific way to form proteins: Proteins are composed of long chains of amino acids. After the amino acids are synthesized and linked together, the resulting chain folds into a three-dimensional structure, which is critical for the protein's function. This folding process is driven by various interactions between the amino acid residues in the chain, allowing the protein to adopt its specific shape and perform its specific function.

Answer: parasitism can help shape biodiversity by exerting selective pressure on host populations and by contributing to the diversity of parasitic organisms themselves.

Explanation: Parasitism is a form of symbiotic relationship where one organism, the parasite, benefits while the other, the host, is harmed. Parasites can have a significant impact on the biodiversity of an ecosystem by selecting and shaping the characteristics of their host species.

Parasites have evolved to infect specific hosts, which means that their survival and reproduction are tied to the existence of their host. As a result, parasites can exert selective pressure on the host population, favoring certain traits and characteristics that make the hosts more resistant or susceptible to infection.

This selective pressure can lead to evolutionary changes in the host population, which can lead to increased genetic diversity. For example, if a parasite infects a population of fish and selects for fish that have more effective immune systems, then those fish will be more likely to survive and reproduce, passing on their advantageous traits to their offspring. This can ultimately lead to the development of new species.

Furthermore, parasites themselves can be incredibly diverse. Studies have shown that parasites can account for a significant percentage of the total biodiversity in an ecosystem. By infecting different hosts and adapting to different environments, parasites can influence the evolution of their hosts and contribute to overall biodiversity.

Answer:

Parasitism, in common with competition, facilitation, and predation, could regulate BD-EF relationships. Parasitism affects host phenotypes, including changes to host morphology, behavior, and physiology, which might increase intra- and interspecific functional diversity.

Answer:

Homologous chromosomes separate from each other during anaphase I of meiosis.

Explanation:

Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the formation of haploid gametes (sperm or eggs) with half the number of chromosomes as the parent cell.

During meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. Then, during anaphase I, the homologous chromosomes separate from each other and migrate to opposite poles of the cell. This is followed by telophase I, cytokinesis, and the formation of two new cells, each with a haploid set of chromosomes.

In contrast, during meiosis II, the sister chromatids of each chromosome separate from each other and migrate to opposite poles of the cell, resulting in the formation of four haploid daughter cells.

Conductivity is the property of matter in which a substance can transfer heat or electricity. So, the correct option is (B).

Conductivity is defined as the amount of heat passing per second through a slab of unit cross-sectional area when the temperature gradient between the two faces is one.

Conductivity is described as the property of matter in which matter can transfer heat or electricity or we can say that matter or substances that conduct electricity. The SI unit of conductivity is Siemens per meter.

Conductivity is of three types which are as follows:

1. Electrical conductivity

2. Thermal conductivity

Answer:

Heart muscles have long refractory period.

Explanation:

Heart muscle cells cannot rely on fermentation for long period of time because heart muscles have long refractory period which does not allow it to use the fermentation process. They have rich blood supply and have capillary density 4 times more than normal skeletal muscles. The anaerobic capacity is limited in the heart which does not allow the heart muscle cells to use fermentation process for metabolism. Our heart requires oxygen in large amount and very quickly for ATP production.

The correct hypothesis supported by the data is hypothesis B: Manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

Based on the given information, neither hypothesis A nor hypothesis D is supported by the data. Hypothesis A suggests that manatees, an abiotic factor (which is incorrect, as manatees are living organisms), experienced a decline in their population due to propeller boats, a biotic factor.

Hypothesis D suggests the opposite, that manatees (an abiotic factor) experienced an increase in their population due to propeller boats (a biotic factor).

Hypothesis B, on the other hand, is supported by the data. It states that manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

This hypothesis aligns with the information provided, as the graph for manatee population shows a decrease over the same 20-year period in which the number of propeller boats increased.

Therefore, the correct hypothesis supported by the data is hypothesis B: Manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

Explanation:

The relationship between the original prokaryotic cells in this scenario can be compared to a predator-prey relationship, where the larger prokaryotic cell acted as the predator and the smaller prokaryotic cell acted as the prey.

A prokaryotic cell is a type of cell that lacks a nucleus and other membrane-bound organelles. These cells are typically small and simple in structure, and they are found in bacteria and archaea. Prokaryotic cells contain a single circular DNA molecule that is not enclosed by a membrane, and they also have a cell membrane and a cell wall. Some prokaryotic cells may have additional structures, such as flagella for movement or pili for attachment, but they do not have the complex internal compartments and structures seen in eukaryotic cells. Prokaryotic cells are important for many biological processes, including nutrient cycling, disease, and biotechnology.

Scientific Theory

Explanation:

The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.

In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.

Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.
