Answer:
- Scientific experiments are not falsifiable.
- Scientific experiments are peer-reviewed.
- Scientific hypotheses are testable
Explanation:
The scientific method refers to the process of examination of scientific hypotheses. This method is rigorous and requires 1-to raise questions about an observed phenomenon, 2-to produce an experiment and 3-to confirm this hypothesis by analyzing the results. The last step of scientific research is the peer review process, where independent researchers (usually 2-3 researchers) review the observed evidence in order to confirm or reject the results obtained from the experimentation. This hypothesis must also be testable, ie, it is imperative that it can be confirmed in further experiments.

If you centrifuge (spin) whole blood, you will find the red blood cells (erythrocytes) at the bottom of the tube and white blood cells atop them. This implies that ________.
Explanation:
Red blood cells are denser than white blood cells
The branch of science that deals with a living being are called biology. There are two types of living beings, one is plants and the other is animals.
What is centrifugation?Centrifugation is a mechanical process that involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity, and rotor speedAccording to the question, the erythrocytes) at the bottom of the tube and white blood cells atop them. This implies that red blood cells are denser than white blood cells and due to heavyweight they accumulate at the bottom.

Do you have reason to suspect that they should become isolated on the same dilution plate
Answer:
Please see below
Explanation:
Since the bacteria Serratia marcescens kept on growing even with higher dilution levels, it can safely be concluded that no, E. coli and S. marcescens would not become isolated on the same plate. The inoculum used should roughly contain 300 cells in order for it to not grow in clumps, rather make separate colonies.
If you find an object
that looks like an organism, how might you
determine if your discovery is indeed alive?
Answer: If it does any of these it is alive: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution.
Explanation: Since all organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to show you that, your discovery is indeed, alive.
Do you think the processes that form and shape the small stream bed are similar to those that form and shape the Grand Canyon? Why or why not?
Answer:
Yes.
Explanation:
The processes that formed the small stream bed are similar to those that formed the Grand Canyon because both are formed by the flowing of river. The river flow through these regions and with this flow they takes rock particles with itself and makes several shapes and structures of that region. So we say that rivers and streams are responsible for the formation of stream bed and Grand Canyon.

The question is incomplete, the complete question is as follows:
Which statement accounts for the hereditary transmission of SDH-linked paraganglioma in a parent specific manner? SDH is:
A) an imprinted gene
B) a y-linked gene
C) an X-linked gene
D) a tumor suppressor gene
Answer:
A) an imprinted gene
Explanation:
A paraganglioma is defined as a tumour that begins in nerve cells and have the ability to disperse in the whole body.
Succinate dehydrogenase (SDH)-linked paraganglioma is a heriditary transmitted disorder through an imprinted gene from parents to their childrens. An imprinted genes are expressed in a parents in a different manner which shows mis-expression of the imprinted genes in a specific region to the next generation.
Hence, the correct option is "A) an imprinted gene "

Most endocrine tissues use a negative feedback mechanism for homeostasis. Which of the following involves a positive feedback mechanism? Group of answer choices cortisol insulin oxytocin thyroid
Answer:
The correct answer is: Oxytocin.
Explanation:
Feedback mechanisms are key elements in the regulation of hormone release and, in the human body, most endocrine systems work by making use of negative feedback, which means that the response generated by the release of the peripheral hormone (for example, insulin), will lead to an inhibition of the stimulus that made the release of said hormone possible - this is very important to control homeostasis.
Positive feedback, on the other hand, is the opposite. This type of feedback mechanism, which is not as common as negative feedback, happens when the peripheral hormone is released and this stimulates the tissue that released the hormone that stimulated the release of the peripheral hormone - this is done so the hormone effect is amplified more and more.
To better illustrate these mechanisms, here are some examples of each:
Insulin. After having a meal, the blood sugar levels rise, which triggers the release of insulin, a hormone that decreases blood sugar levels (glycemia). When this decrease in glycemia is produced, the release of insulin is stopped. This is negative feedback. Cortisol and thyroid hormones are also examples of negative feedback.Oxytocin. This hormone is released from the posterior pituitary gland during labor to produce the contractions of the uterus, which will push the baby through the birth canal. The presence of oxytocin will lead to the release of more oxytocin, so the muscle contractions can increase. This is an example of positive feedback.the graph below compares the rates of reaction of a burning candle and an exploding firework

Explanation:
What is you were an astronaut and interplanetary explorer and you discovered “something” on another planet,like Mars that reproduced by itself, grew in size, took in food, responded to you or other stimuli, but did not seem to be made of cells or possess DNA or RNA. would you consider it to be living or nonliving?
Answer:
I would consider it to be nonliving
Explanation:
The characteristics of life demarcates a living thing from a nonliving thing. These characteristics include the ability to move, ability to respire, ability to reproduce, ability to undergo nutrition (take in food), ability to respond to external stimuli, ability to grow by increasing in size and more importantly must be made up of at least a single cell. Cell is the fundamental and basic unit of all living things.
This object found in Mars may be able to perform every other characteristics of a living thing e.g reproduction, irritability, growth, nutrition etc but to be considered as a living thing, it must consist of at least one CELL, which in turn must contain either a DNA or RNA molecule that carries information about its genetic content.
Hence, according to the universal CELL THEORY that states that "All living things contains one or more cells", this something found on Mars is not considered living.

See the answer below
Explanation:
The complete question reads: James was sick, went to the doctor, and was diagnosed with a bacterial throat infection. His infection was treated with antibiotics. In a few days, James felt much better, but some resistant bacteria survived and, overnight, James was sick again. This time, he had to take a much stronger antibiotic. The resistant bacterial cells illustrate what characteristic of life?
All living things respond to stimuli.
All living things maintain homeostasis.
All living things adapt to changes in their environment.
All living things contain genetic material and reproduce.
The correct answer would be that all living things adapt to changes in their environment.
Generally, all living organisms try to adapt to changing environments. Those that are able to successfully adapt survive in the environment and are able to produce offspring that are also able to survive in the same environment. Organisms that are not able to adapt to a changing environment end up dying from the population. This is an example of evolution by natural selection - the survival of the fittest.
