B. the presence or absence of DNA
C. Plant cells would be green
D. Animal cells would contain a nucleus
SORRY FOR THE LITTLE POINT PLEASE ANSWER ITS DUE IN 2 MINUTES
Answer:
I think the answer is A
Explanation:
The presence or absence of a cell wall is examining cells under a microscope.
What is Cell wall?Cell walls are a specific type of extracellular matrix that cover every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.
The cell wall serves a variety of activities that are essential to plant life, despite being frequently thought of as an inert product used only for mechanical and structural purposes.
These include: giving the living cell mechanical defense and a chemically insulated environment; offering a porous medium for the circulation and distribution of water, minerals, and other small nutrient molecules.
Therefore, The presence or absence of a cell wall is examining cells under a microscope.

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.

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

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

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).

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.
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.
