1. In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are microtubules. 2. Ma
yulyashka [42]

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.

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

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

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

natita [175]

The image shows a red blood cell in different solution. The first image shows an RBC in a hypotonic solutions. The RBC swell and lyse because of the osmotic movement or referred to as hemolysis. The second image shows a normal RBC in an isotonic solution. There is no net change of water to the RBC. The third image shows a shriveled RBC in a hypertonic solution. The water leak out of the RBC briskly than it enters the cell. It is also called as crenated cell.

Answer - Option C - hypotonic solution

Answer:

I don' know but I know this. hope cam help you

One of the reason before why people worship idols is because at that time there was kind person who is a pious or a prophet at that time who tell to a nation about goodness and about God to worship god alone and to follow the law of god. after there died, people of the nation miss them so much until there make a idols of them so that there remember him and to remember of the good teaching about the law of god.

by time to time after the new generation of the nation there don't know much about the idols that their father Glorify them so there start worshipping the idols for goodness like their father do before. After time by time their worship the idols and claim the idols is the god of them. This happen not in one nation but to a many nation before that have different language in a different places that each places god send for them a prophet with their language on this world before. And after time by time people change the teaching and the message of the prophet. Until god send the last final prophet for the hole humankind that is prophet Muhammad peace be upon him.
