Answer:
The correct answer is - chromosomes align at the spindle equator.
Explanation:
Chromosomes move and align at the spindle equator during the metaphase stage of mitosis and other given events take place during the anaphase stage of the mitosis cell division. Metaphase is the second phase of the M-phase of mitosis division whereas anaphase is the third phase.
The metaphase is characterized by the alignment of the chromosomes at the equator whereas the anaphase is separating the chromosomes pulled towards the poles and division of centromeres.
Answer: A.
Explanation: "<u>An emergent property is a property which a collection or complex system has</u>, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood. You will need the whole heart to be able to pump blood."
Explanation for the incorrect answer:
"Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach to biological research.
"
The interaction is seemingly neutral for one of the organisms. For example, a barnacle attached to a whale can travel thousands of miles collecting and filtering food from the moving water. The whale doesn't seem to be affected by the little hitchhikers.
Answer:
True.
Explanation:
Hermaphrodites may be defined as the organism that does not contain the separate sexes. Generally, invertebrates and lower vertebrates are hermaphrodites in the nature.
The male and female gametes are present inside the same organism. The eggs and ova are produced in the same body in case of the hermaphrodite animals.
Thus, the correct answer is option (a).
Most mountains and mountain ranges are parts of mountain belts that have
formed where two lithospheric plates have converged and where, in most
cases, they continue to converge.
