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
Answer:

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

Which of the following is not a function of a vertebrate’s endoskeleton?
a.) Increase speed of digestion
b.) Protect major organs
c.) Offer support and structure
d.) Connect with muscles to create movement
Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).
What is Endoskeleton?
The rigid part which provides internal support of the structure is called endoskeleton which develops from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone etc. The hard part that is on the outside of the body that protects the soft tissues and muscles is called the exoskeleton.
Vertebrates are animals that have a backbone and an endoskeleton which is a skeleton inside their body while invertebrates are animals that do not have a backbone. Invertebrates may have a skeleton on the outside of their body called an exoskeleton, while some invertebrates have no skeleton at all.
It protects major organs, offer support to the structure, connect the muscles to create movement.
Thus, Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (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.

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.
