Answer:
The question "What color is a great horned owl?" does not require the scientific method to be used for getting an answer hence, it is not a scientific question. This question does not require any hypothesis or any other method. It can easily be answered by just looking at the horned owl.
A scientific question has to be a question from which a hypothesis can be made. The hypothesis can be tested through experiments and observations. Results and conclusions from the experiments would result in answering that question.
prophase I : homologous chromosomes are paired
metaphase I : the centrosome replicates
anaphase I: homologous chromosomes are separated
telophase I : nuclear envelopes form around separated chromosomes
Answer:
Cytoskeletal elements play important roles in cell division. The mitotic spindle apparatus is made of "microtubules" and pulls sister chromatids apart, whereas the contractile ring is made of "actin filaments" and required for the separation of daughter cells at the end of the mitotic phase of the cell cycle.
Explanation:
The three chief organizational apparatuses of the cytoskeleton are microtubules (formed by tubulins), microfilaments (formed by actins) and intermediate filaments. All three apparatuses cooperate with each other non-covalently. The cytoskeleton is composed of protein filaments and is found throughout the inside of a eukaryotic cell. The cytosol is the main component of the cytoplasm, the fluid that fills the inside of the cell. The cytoplasm is everything in the cell except for the cytoskeleton and membrane-bound organelles.
Grounds are located where warm and
cold currents converge, where warm and cold currents meet happens to have
regular foggy conditions, as the overlying warm and cold air come in contact
with each other. They also tend to have high biological productivity, because
plankton growth is encourage by the mixing of warm and cold currents. Some of
the world's most productive fishing.
