7 0

For both actin and microtubule polymerization, nucleotide hydrolysis is important for controlling the growth of a microtubule.

Polymerization dynamics enable microtubules to adopt rapidly changing spatial arrangements and, in some cases, perform mechanical tasks according to cellular needs. Microtubules harness the energy of GTP hydrolysis to drive a unique polymerization mechanism called dynamic instability.

Microtubules are one of the main components of the cytoskeleton and are rigid hollow rods approximately 25 nm in diameter. microtubules. are made up of dimers of α- and β-tubulin which polymerize to form microtubules, which are composed of 13 protofilaments assembled around a hollow core.

Explanation:

Some of the micro-nutrients found in fertilizers are:

  • Boron: The support the structural and functional integrity of the plant,
  • Copper: Copper is used for enzyme activation.
  • Iron: It is used for the production of food by the plants.
  • Manganese: It helps in photosynthetic reactions.
  • Molybdenum: It is used for optimizing the growth of plants.
  • Zinc: functions in many ways in plants.

Explain your observations on what organisms need to grow. Also discuss ways in which human activity can impact an organism’s abi
Dima020 [189]

<em>"No man is an island.” This saying is also true for organisms in an ecosystem. No organism exists in isolation.  Individual organisms live together in an ecosystem and depend on one another.  In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival. </em>

<em>So what do these interactions look like in an ecosystem? One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph. While there are a lot of fancy words related to the sciences, one of the great things is that many of them are based on Latin or Greek roots. For example, heterotroph becomes easier to remember when you realize that in Greek, “hetero” means “other” and “troph” means food; in other words, heterotrophs eat other organisms to get their food. They then use the energy and materials in that food to grow, reproduce and carry out all of their life activities. All animals, all fungi, and some kinds of bacteria are heterotrophs and consumers. </em>
