Answer:
Covalent bonds are the types of Bond which is formed by sharing of an electron between two atoms of same element or two different elements. The bond which is formed by the completely lost or gained of an atom is known as ionic bond.
Explanation:
The most common example of covalent bond is formed from carbon atom. The valence of carbon atom is 4. Therefore, it is very hard to gain or lose an electron from the carbon atom. Therefore, the carbon tends to share the electron instead of completely losing or gaining the electron.
Ionic bond is very common and it can be formed by many elements from the periodic table. Ionic bond is more stable and stronger when compared to the covalent bond in nature.
Answer:
Los virus son más pequeños y no son células. A diferencia de las bacterias, necesitan un huésped como un humano o un animal para multiplicarse.
Las bacterias son organismos vivos unicelulares. Tienen una pared celular y todos los componentes necesarios para sobrevivir y reproducirse.
Los virus no se consideran "vivos" porque requieren una célula huésped para sobrevivir a largo plazo, para obtener energía y para reproducirse.
Explanation:
Answer:
A small GTP-binding protein called dynamin assembles as a ring around the neck of each deeply invaginated coated pit, pinch off the vesicle. After the budding is complete, the coat proteins are removed, and the naked vesicle can fuse with its target membrane.
Explanation:
Dynamin - may be a GTPase that takes part in an important role in clathrin-dependent endocytosis and other vesicular trafficking processes by acting like a couple of molecular scissors for newly setup vesicles originating from the cell wall.
1. Cellular Respiration
2. Cytoplasm in body cells ( since it contains organelles in which metabolic reactions take place for eg: chemical reactions of respiration occur during which energy is released for cell activities)
3. Because different cells carry out a different but specific function for the proper functioning of the body
4. The nucleus of a cell contains chromatin which is made up of coils of DNA bound to proteins.
5. Genes contain genetic information for the cell to manufacture particular proteins which determine the characteristics of the organism.
6.Because animal cells have thin, partially permeable cell membranes to control the passage of substances into and out of the cell.. (srry!, I didn’t quite know how to answer this correctly!)

HOPE THIS WILL BE HELPFUL !! But sorry, I didn’t know 2 questions!
Answer:
Explanation:
It removes H2O from the atmosphere during acetyl CoA formation. It releases H2O to the atmosphere during the citric acid cycle.
