Summarize the function of each structure in mitosis

1. In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules. 2. Ma

Answer:

1) In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules.

2) Many cell organelles, most notably the nucleus, are anchored by intermediate filaments which are assembled from a diverse class of proteins.

3) Centrosomes are sites where protein dimers assemble into microtubules.

4) The extension of pseudopodia in amoeba is due to the regulated assembly and destruction of microfilaments.

5) The only cytoskeletal fibers not associated with intracellular movement or whole cell locomotion are the intermediate filaments.

6) During muscle contractions, myosin motor proteins move across tracks of microfilaments.

Explanation:

The cytoskeleton is a very important element of the cell, and is composed of three different structures: microtubules, intermediate filaments, and microfilaments.

Microtubules are structures in the shape of hollow tubes that give shape to the cell. Microtubules also participate in cell motility by providing a route for the organelles to move through.

Intermediate filaments are the only ones that do not participate in cell motility: their main function is to provide mechanical support for the plasma membrane.

Microfilaments are a key component in cell motility, and also associate with myosin (a protein) to produce muscle contraction. Microfilaments also give the cell the ability to grow pseudopods.

List three specific functions of capsules.

Tema [17]

Function. The capsule is considered a virulence factor because it enhances the ability of bacteria to cause disease (e.g. prevents phagocytosis). The capsule can protect cells from engulfment by eukaryotic cells, such as macrophages. ... Capsules also contain water which protects the bacteria against desiccation.

I hope this helps :)

Compare and contrast the types of digestive systems found in worms.

Burka [1]

Many flatworms are parasites which means they live inside or on another organism and they take food from their host. Planarians are scavengers so they feed on dead or decaying material and they are also predators. They feed like a vacuum cleaner. They glide onto its food and inserts a feeding tube into it. Digestive juices flow out of the planarian and into the food. The juices begin to break down the food while it is still outside the worm's body. Then the planarian sucks up the partly digested bits. Tapeworms absorb food from their host's digestive system. Roundworms have a digestive system that is like a tube, open at both ends. Food travels in one direction.
