Answer:
Robert Hooke
Explanation:
With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. It was an important step in the movement away from spontaneous generation

Answer:
The Third Bubble
Explanation:
Answer:
D
Explanation:
A.
If we increased the use of fossil fuels, that would actually increase air pollution, so this is not correct.
B.
Even if we switch to wood, that would still create pollution, and it wouldn't be a lasting and efficient solution. This is not the correct option.
C.
If the Environmental Protection Agency's role is decreased, there will be no regulations for car emissions, and air pollution would increase. This choice is not correct.
D.
If we decrease our dependency on burning fossil fuels and create better regulations for car emissions, that would decrease air pollution. Therefore, D is the right choice.

According to the trichromatic theory of color vision, the eye has cones sensitive to colors associated with ___________. A. red, green, and yellow B. green, purple, and red C. red, green, and blue D. black, brown, and white
Answer:
c. red, green and blue.
Explanation:
The three main colors, also known as the primary colors are Red, Green and Blue. The trichromatic theory believes that the human eye and receive light of three different wavelengths (which are red, green and blue) and is able to combine these three different wavelengths in order to see the entire visible spectrum that make up millions of different colors. As can be visualized by the attached picture below.
According to the trichromatic theory of color vision, the eye has cones sensitive to colors associated with red, green, and blue. Therefore, the correct option is C.
According to the trichromatic theory, commonly known as the Young–Helmholtz theory, the human eye has three different types of color-sensitive cones, each sensitive to a different range of light wavelengths. These cones are most sensitive to red, green and blue light respectively.
Our visual system is able to perceive a wide spectrum of colors by integrating information from these three different types of cones. Different levels of activation of these three cone types and stimuli lead to the perception of additional colors.
Therefore, the correct option is C.

What type of forensic technique should be used? Police discovered a badly damaged corpse the body was damaged beyond recognition the police expert however can use DNA _____ to identify the victim?
Answer:
DNA profiling or DNA fingerprinting
Explanation:
DNA profiling is also known as DNA fingerprinting which is widely used in to determine an individual's DNA characteristics.
DNA profiling is widely used in forensic technique in victim or criminal investigations, where DNA is collected that can be hair, blood, body tissue sample or other. The sample is then compared with other suspect's sample which are expected to to be involved to determine whether there is a genetic match and that will help to identify the victim or criminal.
DNA profiling is used to match genetic formation between people which will help to identify parentage testing as genes inherited in the family is almost same and the the victim body will be identified.
Hence, the correct answer is DNA profiling.
Answer:
DNA fingerprinting

Going "green" means to pursue knowledge and practices that can lead to more environmentally friendly and ecologically responsible decisions and lifestyles, which can help protect the environment and sustain its natural resources for current and future generations. As America moves closer to a clean energy future and becoming "green,"what must be considered, especially when it comes to solar and wind power?
Answer:
Both solar and wind power need to be affordable for people to have them at there homes. They also need to offered to people because some people don’t know about solar or wind energy. Another thing about solar and wind energy is that it has to be safe and professionally installed for it to be safe.

Select one:
a. As cells develop, their genetic makeup changes.
b. As cells develop, some genes are turned off permanently.
c. Stem cells are the only cells that do not have an X or Y chromosome and can therefore go into either a male or female.
d. Stem cells are the only cells that can be implanted.
Answer:
c. stem cells are the only cells that do not have an X and Y chromosome and can therefore go into either make or female
All cells contain the same genetic information. Stem cells are the only cells that do not have an X or Y chromosome and can therefore go into either a male or female. Thus, option C is correct.
What is DNA?
DNA has been known as the molecule that contains the genetic information that is necessary to generate proteins. This is due to the sequence of the nucleotides, which are the monomers of DNA. Each nucleotide has been contained a different base Adenine (A), Timine (T), Guanine (G), Cytosine (C).
When the cell has needs to synthesize the proteins, DNA has not used directly but the transcribed into RNA. This RNA has been directed to the ribosomes, organelles where the protein synthesis has been taken place, and according to the sequence of RNA which is complementary to DNA, the different amino acids has been coded. During translation, aminoacids are joined together to form proteins.
Therefore, All cells contain the same genetic information. Stem cells are the only cells that do not have an X or Y chromosome and can therefore go into either a male or female. Thus, option C is correct.

Mechanical energy has two types viz: kinetic energy and potential energy. Kinetic energy is the energy possessed by a moving object while potential energy is that possessed at a fixed position.
Therefore, in this question, all the examples portrays a moving or stationary object, which makes all an example of mechanical energy. Bouncing ball (moving), water in a reservoir (stationary), book on a table (stationary), person running (moving) etc.
The oceans cover approximately 70% of Earth's surface and also contain about 97% of Earth's water supply. This enormous amount of space provides habitats for a large number of diverse organisms. However, organisms thrive in different areas. Which statement below best describes the distribution of life in the ocean?
All species of aquatic organisms have adapted to all depths of the ocean and are distributed throughout.
Species which thrive in mid-ocean areas are those which are adapted to a warm environment rich in oxygen and photosynthetic organisms.
Organisms which are able to survive in the deepest depths of the ocean must have adaptations that allow them to live in cold dark environments under a lot of pressure.
The upper depths of the ocean are teeming with large organisms that need little sunlight and are not dependent on autotrophs.

a very low temperature
superconductor
a material through which little electric
current moves
conductor
a material through which electric
current flows easily
insulator

but not as well as a conductor
Answer: Semiconductor: a material that conducts electricity, but not as well as a conductor. Superconductor: a material that has zero resistance at a very low temperature. Conductor: A material through which electric current flows easily. Insulator: a material through which little electric current moves.
Explanation: A conductor is a material or a substance that easily conducts electricity. It allows electrons to flow easily from atom to atom; like humans, animals, and metals. A semiconductor is a material that has a level of conduction between a conductor and an insulator, such as the silicon. A superconductor has a high resistance to very low temperatures, such as aluminum. And an insulator has a very low capacity to conduct compared to other conductors, such as glass or porcelain.
