As a body cell grows, the ratio of _______ to volume _________. Before it grows to large, a cell will divide into two ________ cells. So that each new cell receives its own genetic instructions, the cell ________ or copies, all of its DNA.
Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.
Explanation:
As a body cell grows, the ratio of surface area to volume decreases. Before it grows to large, a cell will divide into two daughter cells. So that each new cell receives its own genetic instructions, the cell replicates or copies, all of its DNA.
The volume of a growing cell increases at a larger pace than the surface area. Hence the ratio of the surface area to the volume of the cell keeps decreasing. At a certain point, the signal to divide is given and this leads to the division of the cell into two daughter cells.
Just before the division, the genetic material of the cell is replicated and other important biomolecules are synthesized before the final call can be made.

You are looking out over the ocean and see this:
What can you know about the tide?
When we are looking out over the ocean and see this: We can know about the tide that it must be neap tides. Thus, the correct option is A.
What are neap tides?A neap tide occurs seven days after a spring tide. It refers to a period of moderate tides when the sun and the moon are at right angles to each other in space. A spring tide is a common historical term which has nothing to do with that of the season of spring.
A tide just after the first or third quarters of the Moon when there is least difference between the high and low tides is called as Neap tide. During this time, the Moon and the Sun are at right angles to that of the earth. As a result of this, the high tides are not too high, and the low tides are not too low.
Therefore, the correct option is A.

Explanation:
Do you think that humans and humpback whales share a common evolutionary lineage?
Answer:
Yes!
Explanation:
Yes because when it comes to whales and humans we have a lot in common. They have different behaviors and languages within their own culture as humans do.They come in a lot of sizes and have different behaviors. Just like us and they are also mammals. While other sea creatures have gills.
Answer:
Scientists have used computer analysis to read evolution backward and reconstruct a large part of the genome of an 80-million-year-old mammal. This tiny shrewlike creature was the common ancestor of humans and other living mammals as diverse as horses, bats, tigers and whales.

A scientist observes two stars in the night sky through a telescope. Star A is white in color and relatively dim. The star’s estimated temperature is very high.
Star B is red in color and extremely bright. The star’s temperature is low compared with other stars.
Help the scientist classify the two stars.
Answer:
Star A is a Neutron Star while Star B is a Red Giant
Explanation: Neutron star is a very hot star, very small in size and hence dim and is white in color. A neutron star results after a massive star goes supernova. It is primarily composed of neutrons packed in a small boundary.
star B would be a red giant. This is because, a red giant star is red in color, is very big in size, and has a low temperature. A red giant star is a towards the end stage of a small to an average mass star.

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. A physical change doesn’t break the bonds between atoms of a substance or form new ones. Compounds can be broken down by a chemical change. A chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. What simple substance would a compound break into? The basic elements that make it up! For example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. Which of the following is an example of a chemical change?
A
separating water into different glasses
B
breaking frozen ice cubes with a hammer
C
running an electric current through water
D
boiling water to evaporate it on a stove

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

Which of these factors is involved in earthquake formation?
Answer:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other.
