The correct answer is blinking when light is flashed in the eyes

The blinking of eyes is considered as the reflex action because it is an involuntary closing of eyelids which is elicited by the stimulation of cornea. Any peripheral response can generate blinking of eyes. The purpose of this reflex action is to protect the eyes from foreign stimulus. When a light is flashed on the eyes it served as an external stimulus, as a result of this the eyes blinked to protect the eyes from bright light. It occurs in 0.1 seconds.

Question

What happens to the liquid in wastewater at a wastewater treatment plant?A. It is released into a river, lake, or ocean.B. It is spread on hay fields as fertilizer.C. It is sent to a sanitary landfill.D. It is stored underground in sealed bins.

Solution 1

The cleaned wastewater is discharged into nearby waterways, where it is put to use once more for a variety of things, including providing drinking water, watering crops, and preserving aquatic life.

How is the sludge from the wastewater treatment facility used?

After being cleaned, sewage sludge is either packaged with other materials as well as sold as "biosolid compost" for use in landscaping and agriculture, or it is dried and placed in a landfill, used as fertilizer to agricultural crops, or both.

How is liquid trash disposed of?

Incineration. Hazardous waste, including chemicals, scrap metal, acids, and bases in water and liquids, can be disposed of through incineration. In this method, hot gases and ashes are produced as the liquid waste is burned at extremely high temperatures in combustion chambers.

Where is ejected liquid waste?

The kidneys, which are responsible for eliminating liquid wastes, and the large intestine are the two most significant excretory system organs (for solid wastes). Wastes including urea, salts, and extra water enter the collecting ducts after filtering.

Question

How does volcanic ash in earth’s atmosphere affect solar radiation?

Solution 1

It increases the amount of solar radiation that is reflected into space.Description

Solution 2

Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. Below is an overview of materials that make their way from volcanic eruptions into the atmosphere: particles of dust and ash, sulfur dioxide, and greenhouse gases like water vapor and carbon dioxide.

Question

What is the growing of cells in a synthetic environment

Solution 1

Answer:

The answer is Cell Culturing

Explanation:

Solution 2

Mutations may be caused by environmental factors such as radiation or chemicals. This is the structural and functional unit of all living organisms, and are sometimes called the "building blocks of life." This is growing of cells in a synthetic environment.

Question

Imagine we reach the year 2050 and we have surpassed the the projected global population. World wide we are running out of fresh water. Discuss how the human population may form a new species through evolution. Use at least three of the following terms in your answer: survive, adaptation, fit, random mutation, DNA, offspring, beneficial, environment, reproduce. *Good use of more terms may result in a higher score*x

Solution 1

The human race may survive through survival of the fittest. basically whoever has the biggest stick wins! The body also could adapt to the lack of water so you could preserve your bodily resources and manage them better. Or you could just change the environment to benefit yourself and mankind!

Question

The source of evidence refers to _____. A. how reliable the information is B. the type of information collected C. where the information came from D. the experimental groups being studied

Solution 1

The source of evidence refers to C. where the information came from.

There are two sources of evidence the primary or original source or evidence and secondary source. The primary source, in history, is anything that serves as an original source of information about the topic. It could be an artifact, document, manuscript, diary, autobiography and the like. Moreover, in the field of journalism, a primary source can be a person that has a personal or direct knowledge of a subject or situation or a written document by such a person. Meanwhile, secondary sources are evidences or sources that are extracted or build upon primary sources.

Question

Why is Mendeleev’s periodic table considered a viable scientific model? It showed that Lavoisier’s table was incorrect. It could be used to explain the behavior of all of the elements. It caused other scientists to reject his predictions. It helped scientists discover new elements.

That’s wrong answer is it could be used to exsplain the behavior of all elements

Solution 2

It helped scientists discover new elements

Question

Identify the four principles of natural selection

Solution 1

Variation- Heritable differences that exist in every population are the basis for natural selection
Overproduction- Competition for resources for resources
adaptation- A trait that helps an organism survive and reproduce
decent with modification- Natural Selection will result in species with adaptation that are well suited for survival and reproduction.

Question

Which of the following is an example of an environmental variation? a Marge dyes her hair blue. b Homer inherited baldness from his father's side of the family. c Apu is a tongue roller, but his brother Sanjay is not. d Bart is a boy because he has an X and a Y chromosome.

Solution 1

I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.

Solution 2

Answer:

A. Marge dyes her hair blue

Question

Help asap plz (IM GIVING AWAY 70 POINTS) 1. How are wavelength, frequency, and energy related to each other? 2. Give one example of a type of energy that is considered electromagnetic radiation. 3.How do we use electromagnetic energy? 4. What is the electromagnetic spectrum? 5. Name the only part of the electromagnetic spectrum that humans can see with the naked eye. 6. What are the characteristics of visible light? 7. Red light has the __________ wavelength. 8. Violet light has the __________ wavelength. 9. What is “Roy G. Biv,” and what does it stand for? 10. Even though sunlight looks white, what is it really made up of? 11. What object can you use to bend light? 12. What does the SAGE instrument measure?

Solution 1

1 is The greater the energy, the larger the frequency and the shorter (smaller) thewavelength. Given the relationship between wavelength and frequency — the higher the frequency, the shorter the wavelength — it follows that short wavelengths are more energetic than long wavelengths.

2 is he Sun & its Energy. The sun's energy is the primary source of energy for all surface phenomena and life on Earth.
Combined with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this energy provides for the immense diversity of life formsthat are found ...

3 is The light that we see is a type of electromagnetic radiation. However it is only a very small part of the entire electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum.Electromagnetic radiation is different from sound in that it can travel in space and does not need a medium like air or water to travel

Solution 2

You could use a diamond to bend light and you could also use water.

Question

Which of the following is a source of genetic variation in a population? a Differences due to a car accident. b Differences due to a hairstyle choice. c Differences due to inherited genes.

Solution 1

Answer: c Differences due to inherited genes.

Gene flow or gene migration is an important source of genetic variation. It is a movement or transfer of genes from one population to another. It can take place between two populations of the same species through migration and is brought by reproduction and vertical gene transfer from parent to offspring.
