Wet areas have an advantage over rock layers in terms of fossilization. They produce more oxygen used to harden the specimen.
Only in river valleys does deposition on land occur often. Sediments built up on river floodplains frequently include fossils. Strong currents and waves can be present in some ocean regions that are home to animal life.Hence, there are evidences that wet areas have an advantage over rock layers in terms of fossilization due to presence of abundant water.Water seeps into the remnants, carrying minerals dissolved in it into the crevices where they crystallize as a result of oxidization. The bones and the sedimentary rock that surrounds them both become harder as a result of these crystalline minerals.learn more about fossilization here: https://brainly.com/question/14529748

Describe artificial selection, and explain how it is different from natural selection.
Answer:
Starting with natural selection, the most robust and most intelligent animals survive over the weakest. The weak animals eventually die off because they can't keep up with nature. Artificial selection isn't natural; certain species are being targeted on purpose and decide whether to stay alive or not. At this point, it is not at all about whether the species can survive or not because it's most likely being protected.

Which organism does a virus infect?
animals
bacteria
plants
fungi
A virus can infect animals, bacteria, plants, and fungi.
A virus can infect a range of organisms, including animals, bacteria, plants, and fungi. Viruses are unique infectious agents that require a host cell to replicate and complete their life cycle. They possess specific mechanisms to infect and hijack the cellular machinery of their host organisms.
In animals, viruses can cause a variety of diseases, ranging from the common cold to more severe conditions such as influenza, HIV/AIDS, and COVID-19. Bacteriophages, a type of virus, infect bacteria and can play a crucial role in regulating bacterial populations in various environments.
Plant viruses can impact agricultural crops, causing diseases that affect crop yield and quality. They can be transmitted through vectors such as insects or through infected seeds.
Fungal viruses, known as mycoviruses, infect fungi and can have diverse effects on their host fungi, including alterations in growth, pathogenicity, and reproduction.
Overall, viruses have evolved to exploit a wide range of organisms, adapting to specific host cells and causing various outcomes depending on the virus-host interaction.

In experiments intended to measure conformity it was found that
In experiments designed to measure compliance, observed participants were found to tend to obey authorities, even if their orders contradict individual common sense.
What does the Milgram experiment say?The Milgram Experiment (or Milgram Experiment) was a scientific experiment developed by psychologist Stanley Milgram. The experiment aimed to answer the question of how observed participants tend to obey authorities, even if their orders contradict individual common sense.
With this information, we can conclude that Milgram wanted to investigate what circumstances led men to commit barbarism and observe how far they would be able to go if there was a superior responsible for their actions or if he gave them instructions to violate integrity and infer pain to the other.

which dental material would you say is the most versatile and widely used today and why?
One of the most adaptable restorative materials in dentistry is dental amalgam. It accounts for over 75% of all restorative materials used by dentists.
What is amalgam?Dental amalgam is a mixture of liquid mercury and metal alloys used to treat cavities caused by tooth decay in dentistry. [1] Mercury (50%) is typically found in low-copper amalgam, along with silver (22–32%), tin (14%), zinc (8%), and other trace metals.
Because of the constant expansion and contraction of amalgam fillings, they can sometimes shatter the tooth. Leakage is also less likely with composite fillings. A leaking filling indicates there is a small breach between the filling and your tooth, which allows dirt and saliva to enter and cause decay.

Based on your knowledge of immunological memory explain to your patient the physiological mechanisms that underlie active immunity and how it protects you from infections. Be sure to include a description of primary and secondary immune responses in terms that she will understand.
Immunological memory refers to the ability of the immune system to react previous antigen infections.
What are primary and secondary immune responses?The primary immune response refers to the initial interaction between the immune system with pathogenic microorganisms (e.g., bacteria).
The secondary immune responses refer to the second contact with the same pathogenic organism, which enables to the organism create specific antibodies against this pathogen through a process called immunological memory.
Active Immunity is a term used to refer to a type of acquired immunity caused by previous exposure to a pathogenic microorganism and/or vaccine inoculation.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.
The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.
Which part of the scientific method is best illustrated by the biologist wondering why there were so few frogs in the second year compared to the first?
a making an observation and asking a question
b collecting data
c setting up an experiment
d forming a hypothesis
Making an observation and asking a question is a part of the scientific method that is best illustrated by the biologist wondering why there were so few frogs in the second year compared to the first. Thus, the correct option is A.
What is the Scientific method?The scientific method may be defined as the procedure of objectively confirming attributes through testing and experimentation. It includes observation, hypothesis, prediction, operating an experiment, and finally investigating the results.
A biologist collected the data on the frog population before industrialization, but after a year there should be a considerable reduction in the population of frogs observed by a biologist. The cause of it is also determined by the biologist very well.
