Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings.what does arrows mean in science
What changes when a cell divides into two daugther cells to make it easier for the cells to exchange materials across the surface of the cell? A. Cell division does not make it easier to transfer materials across the cell surface. B. The new cells move materials faster. C. Each new cell has an increased surface area to volume ratio
The new cell has an increased surface area to volume ratio is a process that makes easier the exchange of materials across the surface of the cell (Option C).
What is cell division?Cell division is the process by which cells generate new daughter cells, which may be due to mitosis or meiosis in higher organisms.
Cell division is able to increase the surface/volume ratio and therefore it facilitates the movement of materials in the resulting cells.
In conclusion, news cell has an increased surface area to volume ratioand it makes easier the exchange of materials (Option C).

The cell cycle is the life of the cell from the time it is first formed from a dividing parent cell until its own division into two cells
Explanation:
cell cycle is made up of three main parts: interphase, mitosis, and cytokinesis. Most biologists agree that interphase makes up the period of time that a cell would be preparing for cell division. Cells spend the majority of their lives in this stage. During interphase a cell is going to be growing, replicating its genetic material and essentials to carry out cell division, and proofreading the genetic material to ensure replication has occurred correctly. This doesn’t sound like much, but it’s actually the longest part of the cell cycle. Once this is complete, the cell will then go through cell division and, theoretically, split into two new cells (cytokinesis).
How cytokinesis works will depend upon the type of cell that is dividing. Here is an image that summarizes the differences in cytokinesis in plant cells and animal cells, which is the classic example used in many introductory biology courses:

Explain how advancements in engineering and technology over the years have allowed scientist to learn about mars and earths moon.
Telescopes on Earth and in orbit around Earth provide scientists with information about our solar system. That information is used to plan where spacecraft fly and where they “point their cameras.” NASA and other agencies send robotic spacecraft to fly by, orbit, or land on other planets and moons.

For the compound C₆H₁₂O₆, what type of bond would join the elements and why?
1. covalent because an electron is transferred from a C atom and O atom to a H atom.
2. covalent because electrons are shared between the C, H, and O atoms
3. ionic because an electron is transferred from a C atom and O atom to a H atom.
4. ionic because electrons are shared between the C, H, and O atoms
Answer:
4. Ionic bond because electrons are shared between the C,H and O atoms.
Explanation:
The atomic no. of carbon=6
Electronic configuration=2,4
The atomic no of H=1
E.C=1
The atomic no of O=8
E.C= 2,6
Therefore to attain octate state, they will share electrons

Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?
Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.
Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.
