The cytoskeleton provides energy to cilia
Explanation:
The motion of hair-like structures or axonemes called cilia or flagella are done through sliding movements of one another. This motion needs energy and motor protein molecules called dynein.
Dynein is a cytoskeletal motor protein present in the cytoskeleton and moves in the microtubules and converts the chemical energy in the ATP to mechanical energy to power the sliding and bending movements of cilia.
Apart from facilitating movement, cytoskeleton also contains other proteins which helps it to provide shape and support.
Answer:
Encontré esto en un texto de microbiología, tal vez sea útil.
Explanation:
"Las cianobacterias y los cloroplastos de las plantas tienen ambos fotosistemas, mientras que las bacterias fotosintéticas anoxigénicas sólo utilizan uno de los fotosistemas. Ambos fotosistemas son excitados simultáneamente por la energía luminosa. Si la célula requiere tanto ATP como NADPH para la biosíntesis, entonces llevará a cabo una fotofosforilación no cíclica".
Si estoy equivocado, pido disculpas. También lo he sacado de un traductor así que si suena mal también me disculpo por ello.
Answer:
the division of cytoplasm is unequal in oogenesis, whereas it is equal in spermatogenesis
Explanation:
Spermatogenesis includes meiosis in primary spermatocytes. These are the diploid cells and completion of meiosis in one primary spermatocyte forms four haploid spermatids. The process of cytokinesis at the end of meiosis-I and meiosis-II equally divides cytoplasm among the daughter cells. Therefore, all the cells produced have an equal amount of cytoplasm.
On the other hand, oogenesis includes unequal cytokinesis by the end of meiosis-I and meiosis-II. It produces a larger secondary oocyte and a relatively smaller first polar body by the end of meiosis-I. Similarly, the mature egg cell is also larger than the second polar body. This occurs so that the zygote can have enough cytoplasm to enter mitosis.
B is the answer to this question...
Answer:
Hmm.
Explanation:
<em>'Oils are fats that are liquid at room temperature, like the vegetable oils used in cooking. Oils come from many different plants and from fish. Oils contain more monounsaturated and polyunsaturated fats. Solid fats are fats that are solid at room temperature, like beef fat, butter, and shortening.'</em>
