Answer:
The word adapt means to get adjusted to a change.
yes, survival in a certain environment is similar to evolution. Both must use adaptation in order for life to keep living through changes in the environment. Each help life sustain itself in a very unique way.
Explanation:
Answer:
A. maintenance of axons is not a cellular activity associated with microtubules.
Explanation:
Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
Answer:
O fuso mitótico
Explanation:
fuso é uma estrutura feita de microtúbulos, fibras fortes que são parte do "esqueleto" da célula. Sua função é organizar os cromossomos e movê-los durante a mitose. O fuso cresce entre os centrossomos a medida que eles se separam.
Answer:
(a) bat wing and human hand
Explanation:
The homologous structures are structures at living organisms that are the same, very similar, or have the same function, despite the organisms having different appearance. This can mostly be seen in the bones of the animals, and this type of structures more often then not suggest a distant common ancestor between the species. Usually the homologous structures appear among animals from the same class, so it can be expected that animals from the mammalia class can have these structures, or animals from the reptilia etc. In this case we have the bat wing and the human hand. Both have similar bone structure, and the function of the bones in the bat wing and the human hand is also similar. Both of them are in the class of mammalia, and they do share a very distant common ancestor in the small shrew-like mammals during the reign of the dinosaurs.
