[tex] \huge \color{magenta}{ \boxed{ \large \sf \color{blue}{d. \: Camouflage}}}[/tex]
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.experiment yeast fermentation ，what is the purpose of boiling the glucose solution earlier？
Answer:
The correct answer is - to sterilize it and remove any oxygen.
Explanation:
Boil the glucose solution to sterilize it and remove any oxygen, leaving behind the glucose needed for anaerobic respiration. High temperature kills all the microbes and sterilizes the solution.
Boiling the glucose solution earlier also helps in removing the oxygen from the solution for preparing the anaerobic respiration in the experiment desired. Sterilization of the solution also helps it in avoiding any microbes to present in the solution and affect the experiment.
Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Sobre la pregunta:
Cucigrama. Pregunta 1 vertical. Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Answer:
Intestino delgado
Explanation:
El intestino delgado es el organi mas largo del tubo digestivo, pudiendo medir 7 metros de longitud y 3 cm de diametro. Se caracteriza por estar sumamente plegado sobre si mismo. La primera porcion, llamada duodeno, recibe secresiones de glándulas biliar y pancreática, y las mezcla con enzimas digestivas. Esta mezcla se encarga de degradar la comida y transformarla en sustancias solubles, como amino ácidos.
Es en el intestino delgado donde ocurre la absorción de nutrientes. Las paredes intestinales estas cubiertas por microvellosidades que aumentan la superficie de absorción.
Las microvellosidades son células que componene el epitelio columnar, y que extienden proyecciones hacia el lumen del organo.

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).

Which gas is used by humans in the process of cellular respiration?
Answer: Oxygen
Explanation:
During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

When the ocean absorbs CO2 it leads to what?
Explanation:
Each liquid falls somewhere along a scale with acid at one end and alkaline at the other. Normally, ocean water is less acidic than fresh water. Unfortunately, as the ocean absorbs more and more carbon dioxide from the atmosphere, it becomes more acidic. Lemon juice is an example of an acidic liquid.
Answer:
If the ocean absorbs a lot of CO2 it is most likely to become acidic
What kind of virus caused the 1918 pandemic?
Answer:
The answer is Spanish flu
Answer:
H1N1 virus with genes of avian origin
Explanation:
The outbreak was caused by an influenza type, where the subtype of it is know as H1N1 virus.(. Characterization of five of the eight RNA segments of the 1918 influenza virus indicates that it was the common ancestor of both subsequent human and swine H1N1 lineages, and experiments testing models of virulence using reverse genetics approaches with 1918 influenza genes have begun in hopes of identifying genetic features that confer virulence in humans.....

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
