Answer:
Researchers refer to DNA found in the cell's nucleus as nuclear DNA. An organism's complete set of nuclear DNA is called its genome. Besides the DNA located in the nucleus, humans and other complex organisms also have a small amount of DNA in cell structures known as mitochondria.

In carbonization, why is the fossilized material called a carbon film?
Answer:
When an organism dies or a leaf falls, it sinks into the earth's layers and decomposes. A carbon film is made when the oxygen, hydrogen and nitrogen of the organism disappear, leaving a thin layer of carbon. This process is known as distillation or carbonization.

A(n)_______________wave can travel through empty space or through matter.
There are_____________types of wave motion-transverse ________________, and a comination of both.
This is about WAVE and this is SCIENCE
Answer:
For the first one it is Electromagnetic waves and the second one is longitudinal and transverse and water water waves (I’m sorry if I get the second one wrong for you but the first I put is right)
Explanation:
An electromagnetic wave can travel through empty space or through matter.There are 2 types of wave motion-transverse ,longitudinal and a combination of both.
What is an electromagnetic wave?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

What is the significance of a gene?Immersive Reader
Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. These small differences contribute to each person’s unique physical features.
I really need this plz dont take points ill mark brainliest Transitional fossils are fossils of organisms that have characteristics of their ancestors’ species and their descendants’ species. Why do you think these fossils are important to the study of evolution? Do you think the word transitional is a scientifically appropriate description for these fossils?
Knowing how fossils form, do you think it’s likely that humans will ever piece together a complete fossil record for every species that ever existed on Earth? Why or why not?
Answer:
- Fossils are an important part of the study of human evolution When a plant or animal dies its body is acted upon by various forces of nature like wind, air; With time body decomposes and gets covered by layers of soil in millions of years Due to increasing pressure with every layer of soil getting added it creates an impression of the body while it further decays, Even it is acted upon by hot temperature inside So even after millions of years of extinction of a species we can study about it looking at its impression in soil known as Fossil one of the ways is.

Rotation describes the circular motion of an object around its center.
24 hours is what we think of as being a complete day,and the time it takes to transition from day to night and back again. It actually takes the Earth 23 hours, 56 minutes, and 4.09 seconds to rotate once on its axis.
Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around earth vertically.
The distance around the earth is 360 degrees. The meridian that runs through Greenwich , England is internationally accepted as the line of 0 degrees logitude, or prime meridian.
The September equinox is around September 22-24 and night and day are nearly the same,
All orbits are elliptical, which means they are an ellipse; similar to an oval.
Some are spiral galaxies, like the Milky Way. some are egg-shaped elliptical galaxies, and the rest are called irregular galaxies.
Hemispheres experience roughly equal amounts of daytime and nightime. On Earth, there are 2 equinoxes every year; one around March 21 and another around Sept 22.
An Eclipse takes place when one heavenly body such as a moon or planet moves into the shadow of another heavenly body.
The moons penumbra causes partial solar eclipses, and the Earths penumbra is involved in penumbra lunar eclipse. The penumbra is lighter type of shadow.
The umbra (Latin for 'shadow') is the innermostand darkest part of a shadow.
Thebword vernal entered English in the 16th century, tracing all the way back to the Latin word ver, meaning spring.
Moon passes through the earths shadow ; Total, Partial, and Penumbral lunar.

Knowing how fossils form, do you think it’s likely that humans will ever piece together a complete fossil record for every species that ever existed on Earth? Why or why not?
Answer:
Fossils tells a story of the relationship between the ancestors and this allows scientists to determine the common pattern in development. These fossils are also used to prove the theory of evolution. Yes the synonym of transitional is midway or also the middle. Fossils are fossils that have traits of their ancestor. These fossils exist between the middle of their ancestor.

Eric said, “I took these photos from the same hill behind my house on three different nights. If half of the Moon is always illuminated and the other half is always dark, then why does the Moon look so different on different nights?”
Answer:
it is called waning and waxing It's because the moon is a world in space, just as Earth is. Like Earth, the moon is always half illuminated by the sun; the round globe of the moon has a day side and a night side. And, like Earth, the moon is always moving through space. it is also because of the position of the earth and the moon.
Explanation:
The reason why the moon looks so different on different nights is because of a phenomenon called:
Waning and WaxingWaning and Waxing is a phenomenon which is used to describe the reason why the moon is half illuminated by the sun and why the other half is dark.
This is because the moon is always moving through space and like te Earth it has a "day and night" schedule depending on the location on the earth's crust.

When mineralization occurs, what is the nature of the fossilized material?
Answer:
Fossils could be anything dug up from the ground, including crystals or human artifacts, but some of these objects aren't organic. Among the ones that were organic, they turned into a recognizable resemblance to living organisms.
Explanation:
there you go
Answer: here is an example
Explanation:
A common mode of fossilization is mineralization, the replacement of organic material by inorganic minerals. The most common dinosaur fossils are the mineralized remains of bones and teeth. Bones are composed of calcium phosphate and organic material. Common mineralizing media are calcite, iron minerals, and silica.
