What two characteristics must a question have to be a valid scientific

Answers

Answer 1

Answer:

A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e. can be tested by someone through an experiment or measurements), leads to a hypothesis that is falsifiable (means it should generate a hypothesis that can be shown to fail), etc.

Hope it helps you.

what type of ecosystem service is the bee.
A. Provisioning
B. Regulating
C. Supporting
D. Cultural

Answers

Answer:

Provisional (livelihood framework)

Regulating services (ecosystem cascade framework)

Please read explanation.

Explanation:

The type of ecosystem service the bee offers includes pollination and this falls under regulating service.

It also offers food and medicine and thus also offer provisioning ecosystem service

Wild bees provide a broad spectrum of

ecosystem services that range from provisioning to regulating to cultural.

Provisioning ecosystem services is the focus when using a livelihoods framework but regulating ecosystem services are also often present if using the ecosystem cascade framework

Which of the following is a true statement about extinction?
A. Extinction is the death of a species or a larger taxonomic group.
B. It is estimated that presently we are losing hundreds of species every year due to human activities.
C. It is estimated that as much as 38% of all species, including most primates, birds, and amphibians, may be in danger of extinction before the end of the century.
D. All of the statements about extinction are true.
E. Many extinctions are associated with climate change.

Answers

Answer:

Extinction is defined as the complete elimination or termination of one of a kind of organisms or different taxa, generally species. The extinction of species can be due to human activities, climate change, loss of habitats, and other natural causes. Hence, the correct option is D.

Explanation:

Extinction is the end of a certain group, taxa, phylum, or most prominently species. There are several reasons for the extinction of species or larger taxonomic group, such as human activities, the introduction of dangerous species, loss and destruction of habitats, illegal trafficking, climate change, and human activities.

Human activities such as deforestation, urbanization, and mining are some of the major causes of the loss of species and their extinction. Due to these activities, hundreds and thousands of floras and faunas are on the verge of extinction.

Approximately more than a thousand species have been extinct over the past 500 years. Almost 38 percent of the known species have been extinct or will be extinct, which includes primates, birds, animals, and amphibians. Some of the examples of extinct species are Dodo, passenger pigeon, mammoth, and Pierolapithecus.

Climate change is one of the major reasons for the loss of biodiversity. Recent research has estimated that the majority of the species will be lost over the next fifty to 50 years.

PLSS HELP QUICH ILL GIVE 65 POINTS ty

Answers

Answer:

Thrust and Lift.

Method:

There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.

How does the pressure under the wing affect the lift?

The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.

How are impulses received to the brain? Step-by-step???

Answers

So, impulses are basically reactions from something else. So, in the brain, there are neurons, which are also known as brain cells. They have two main and really important parts, called the dendrite and the axon. The dendrite receives the impulse, either from the central nervous system (CNS) or from the peripheral nervous system (PNS). After this event, the axon transfers and carries the impulse away from the cell body. Also, the impulse travels through a little gap in between neurons called the synapse, before the impulse travels to the next neuron. And, remember, this process is not slow. This process occurs in a matter of milliseconds. Think about it. If you burn your hand from something really hot, you will react to that really fast as an impulse. Millions of neurons will react to that in just a second. That's why science is so cool. It has so many interesting topics and fascinating facts, like this. Anyways, I hope this helped you. Enjoy your day.

 

Dendrites get impulses. Axons carry impulses.

sweating which releases heat.
© By opening and closing pores in their leaves, plants continuously exchange oxygen and carbon dioxide with
the atmosphere.

O Feelings of hunger and then fullness affect the length of time between meals and quantity of food you eat,

0 A sensor detects CO 2 levels in the blood and triggers an increase or decrease in the rate of breathing.

Answers

In biology, homeostasis refers to the mechanisms by which biological systems maintain an internal state of steady conditions. The state of homeostasis is fundamental to ensure the survival of biological systems.

All of the examples above are biological responses for maintaining homeostasis EXCEPT a cancerous tumor continues to grow larger and then metastasizes, spreading to new areas of the body.

In cancer, the homeostasis of the system is lost and then cancer cells proliferate in an uncontrolled fashion, thereby leading to metastasis.

Normal cells lose their homeostasis and convert into cancer cells by accumulating mutations that lead to the inactivation of tumor suppressor genes and/or activation of oncogenes.

Compare between tertiary and quaternary structure of protein and write in details how folding of

protein occur in each structure?​

Answers

Answer:

Tertiary structure is formed by the folding of the secondary structure sheets or helices into one another. The tertiary structure of protein is the geometric shape of the protein. It usually has a polypeptide chain as a backbone, with one or more secondary structures. The tertiary structure is determined by the interactions and bonding of the amino acid side chains in the protein.

It usually has a polypeptide chain as a backbone, with one or more secondary structures. The tertiary structure is determined by the interactions and bonding of the amino acid side chains in the protein.Quaternary structure results from folded amino-acid chains in tertiary structures interacting further with each other to give rise to a functional protein such as hemoglobin or DNA polymerase.

Why are scientific journals considered a superior resource compared to other sources of scientific information?

Answers

Scientific journals are generally specialized for distinct academic fields or subdisciplines, and they are the most important way of communicating research findings.

In order to acquire a deeper knowledge of the facts and conclusions, the research frequently challenges prevalent assumptions and the research data given in the published research findings.Scientists disseminate these research findings in scientific journals to make it publicly available to the masses.Scientists describe the study they're building on in scientific publications and journals, as well as their research methodologies, datasets and data processing tools, and their data interpretation.

On the other hand;

Scientific information is concerned with investigating the characteristics and behavior of information, the forces influencing the flow of information, and how it is being processed for optimal usability and usefulness.

It deals with the creation, gathering, categorization, retention, retrieval, interpretation, transmission, and usage of data.

Thus, from the above explained concept we can conclude and agree that:

Scientific journals are far considered superior resources as compared to the sources of scientific information due to the fact that it is scientific journals are peer reviewed(i.e. experts in the field have used different research findings and methodologies) for its validation.
