experiment yeast fermentation ，what is the purpose of boiling the glucose solution earlier？
Answers
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.

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
Answers
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
Answer:
4. Ionic bond because electrons are shared between the C,H and O atoms.

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
Answers
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).

Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Answers
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.
