Scientists once believed that Tyrannosaurus rex dragged its tail along the ground. Today, they know that T. rex did not drag its tail but held it aloft, above the ground. This change in scientific consensus happened because
Answer:
Because all the scientific discoveries must be supported by various studies in order to regarded as valid.
Explanation:
It is known that scientific discoveries are getting updated and renewed constantly, however, both of these have nothing to do with the believing in one's idea more than another. It is also witnessed that some of the scientists do support the notion that the T-rex dragged its tail. However, now it is known that T-rex did not drag its tail but held its aloft above the ground. This change in scientific consensus by various scientific discoveries, which would have been supported by numerous studies in order to be regarded as valid.

Why is prior knowledge so important in science
Prior knowledge allows you to make a well-informed hypotheses and better-planned experiment. However, you do not want prior knowledge to bias your experiments in any way.

As newts' poison became more toxic, the garter snake's resistance to it became more efficient. This is an example of _____. coevolution divergent evolution convergent evolution adaptive radiation
Answer:
Coevolution
Explanation:
Coevolution is the process of reciprocal adaptation of two or more species or populations due to their close interaction for a longer period of time. It is a mutual adaptation and occurs by development of certain morphological and behavioral features in each of the species. Increased efficiency of Newt's poison is rendered less harmful by garter snake as they develop more resistance for it.
what are the three main parts of the scientific process?
a) predicting, inferring , and drawing conclusions
b) activating knowledge, and inferring
c) observation, experimentation, and scientific
d) data collection, analysis, and hypothesis formation
The scientific process consists of three main parts: observation, experimentation, and scientific reasoning.
Option (c) is correct.
Observation involves gathering information about a phenomenon or a problem through the senses or using instruments. It is the first step in the scientific process and provides the foundation for further investigation.
Experimentation involves designing and conducting controlled experiments to test hypotheses or theories. Through carefully planned experiments, scientists manipulate variables and collect data to analyze and draw conclusions.
Scientific reasoning is the process of analyzing data, evaluating evidence, and drawing logical conclusions based on the results of experiments. It involves critical thinking, interpreting data, and identifying patterns or relationships.
The scientific process is an iterative and ongoing cycle. After drawing conclusions, scientists often refine their hypotheses and design new experiments to further investigate the topic or expand knowledge in the field.
While options a), b), and d) touch upon aspects of the scientific process, option c) provides a more comprehensive and accurate representation of the main components involved in scientific inquiry.

When humans breed cows for better meat, this is called
Answer:
Selective breeding or artificial selection
Explanation:
Well, in this case humans are deciding to perpetrate a feature, in this case meat quality.
In nature, the so called natural selection ''chooses'' the survival of certain phenotypes which selects the fittest organisms. In the case of selective breeding, it's the humas who selects a particular phenotype.
A human skin cell, in prophase of mitosis, contains 46 chromosomes. how many chromatids does it contain in total?
In which of the following ways is DNA replication similar to transcription?
A) New cells are created after both have happened.
B) Cytosine pairs with guanine in both.
C) Both take place in the cell cytoplasm.
Answer:
B) Cytosine pairs with guanine in both.
Explanation:
DNA replication is the process by which DNA makes an identical copy of itself during cell division. In this process the DNA polymerase adds a new strand of DNA to the template strand by matching Cytosines with Guanines and Adenines with Thymines.
In transcription a copy of a specific DNA fragment is made, however, this copy has Adenines paired with Uracils instead Adenines with Thymines.
In both, replication and transcription Cytosine pairs with guanine.

How does water's specific heat relate to its usefulness for life give examples?
Water's high specific heat stabilizes temperature, vital for organisms' survival, regulates body temperature, and influences climate patterns.
Water's high specific heat, defined as the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius, is crucial for life on Earth. This property enables water to absorb and store large amounts of heat energy with minimal temperature change, thereby moderating temperature fluctuations in the environment and providing thermal stability.
In biological systems, this thermal stability is essential for maintaining relatively constant internal temperatures, which is vital for the proper functioning of organisms.
For example, in humans, water's high specific heat helps regulate body temperature, preventing rapid overheating or cooling. Additionally, aquatic ecosystems benefit from water's ability to absorb and retain heat, maintaining relatively stable temperatures in rivers, lakes, and oceans, which is crucial for the survival of aquatic organisms.
Moreover, water's high specific heat also plays a role in climate regulation on a global scale. The oceans act as heat reservoirs, absorbing excess heat from the atmosphere during the day and releasing it at night, thereby influencing weather patterns and climate conditions. Overall, water's high specific heat is a fundamental property that contributes to the suitability of Earth for life as we know it.
Neurons communicate with other neurons and stimulates effector cells which includes both blank and blank?
Neurons use electrical and chemical signals to communicate with other neurons and with effector cells, which are muscle cells and glands. They do so through synapses where neurotransmitters are released to convey signals.
Neurons communicate with other neurons and stimulate effector cells which includes both muscle cells and glands.
Neurons are excitable cells capable of creating tiny electric currents to transmit signals. They consist of dendrites, a cell body, and an axon. The dendrites carry information toward the cell body, and then the signal travels along the axon to reach either another neuron or an effector cell. At the point of contact, which is the synapse, neurotransmitters are released to convey the signal to the next cell. Muscle cells and glands are common targets for these signals, ultimately resulting in motion or secretion, respectively.
The communication between neurons, and from neurons to effector cells, is essential for the nervous system to control body functions, ranging from the simple reflex action to complex behaviors and cognitive processes.
Marge Simpson decided to start a new garden in her backyard. She heard that plants compete for space and decided to test this idea. She bought a mixture of flower seeds and some potting soil. She put the same amount of soil into each of 5 plastic cups. In the first cup she planted 2 seeds, in the second cup she planted 4 seeds, in the third cup 8 seeds, and in the fourth cup she planted 16 seeds. In the last cup she planted 32 seeds. After 25 days, she determined which set of plants looked the healthiest. what is the 1 independent variable 2 Dependent variable(DV) 3 Controlled variables 4 Hypotesis
Answer:
The correct answer will be -
1. Independent variable - the number of seeds
2. Dependent variable - growth of the plant
3. Controlled variables - amount of soil
4. Hypothesis - plant growth is directly proportional to the provided space.
Explanation:
In a scientific experiment, the variables could be categorized as dependent variables(to be studied), independent variables (can be manipulated) and constant (kept constant).
A scientific hypothesis is the prediction or an idea based on the previous work and observations which could be tested to answer the question.
In the given question, the variables to be tested is growth of the plants while the variables which can be manipulated is the number of seeds. The variable kept constant is the amount of soil added to the cups and the hypothesis will be the plant growth is directly proportional to the provided space.
