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.

A similar reaction is used frequently in laboratory experiments as an indicator. Can you guess what that might be?
We mixed baking soda with vinegar and drew on a piece of paper when it was done bubbling, then took a sponge and covered the paper in grape juice.
Answer: ph scale
Explanation:
When baking soda is mixed with vinegar, bubbling is observed. This is because of a chemical reaction which involves the evolution of carbon dioxide gas. This reaction is used as an indicator of carbon dioxide.
What is an Indicator?An indicator in chemistry is any substance that gives a visible sign or indication of a chemical species by a change in color. An indicator is generally used to identify an acid or an alkali present in a solution.
Indicators are weak acids or alkalis that show a change in color as the concentration of hydrogen ions in solution changes. Commonly used chemical indicators include Litmus, turmeric, Methyl Orange, phenolphthalein, etc.
When baking soda is mixed with vinegar evolution of gas bubbles is observed. This gas when passed through lime water, the solution turns milky which confirms the presence of carbon dioxide in solution.
Therefore, chemical indicators can be used in identification of a chemical species.

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.

Greg rubs the balloon on his wool sweater, and the charges on the balloon separate so that there are negative areas and positive areas. Which of these statements correctly describes what happens as a result?
The thread will bend so that positive charges are far away from negative charges.
The thread will straighten so that positive charges are close to positive charges.
The negative charges in the thread will attract negative charges on the balloon.
The positive charges in the thread will move toward negative charges on the balloon.
Answer:
'opposites attract'

galaxy. One of billions of heavenly systems consisting of numerous stars. An example is the Milky Way.
orbit The curved pathway of a heavenly body through space.
vernal equinox The spring equinox, on about March 21, when days and nights are of equal length.
eclipse. Complete or partial blocking of light passing from one heavenly body to another, causing the darkening of one heavenly body by a shadow.
penumbra The lightest part of the shadow (around the edges) outside of the complete shadow formed during an eclipse.
umbra The darkest part of the shadow formed during an eclipse.

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.

the same direction.
D. The tide is smaller than normal because the gravitational forces of the sun and moon pull in
opposite directions.
Answer:
A. because this is a spring tide.
Explanation: The sun and the moon are working together, their gravitational forces pull on the tides more. Your question said "The tide is larger than normal because the gravitational forces of the sun and moon pull in the same direction". They are working together to cause higher than normal tides.
