Answer:
D) Because it can share four electrons in covalent bond.
Explanation:
The correct option is Option D.
Because it can share four electrons in covalent bond.
All other are incorrect because,
A = it can share four electrons in ionic bond.
Carbon share its electron and form covalent bond. It can not form ionic bond.
B = Because it can share six electrons inmetallic bond.
It is also incorrect because metallic bond is only formed by the metals and also there are only 4 valance electrons in carbon not six.
Option C = Because it can share four electrons in hydrogen bonds.
It is also incorrect because carbon can not form hydrogen bonds.
Answer:
True
Explanation:
The observed cell is a plant cell because of presence of cellulose coating on cell membrane. The plasmodesmata are the a layer between cell and cell membrane of plant cells that is porous in nature and enables communication between cell and outside environment. It is obvious to find this with cellulose coating. These plasmodesmatas have same function as gap junction animal cells.
Answer:
co2 reacts with hydrogen in a reversible reaction to form carbonic acid
Explanation:
if u want the equation lem me know
Abscission layer is the layer of cutinized parenchyma cells that develops in the abscission zone. The abscission zone form across the base of the plant part, where the break eventually occurs. During the photosyntesis chlorophyll using sunlight produces sugar and storches which are used as food by plant. And sugar accumulate in leaves.
