Answer:
C) commensalism
Explanation:
because commensalism is that type of biological interaction in which members of one specie are getting benefit while the other members of other specie are not getting any benefit nor harm.
Answer:
Pulling apart or separation of sister chromatids
Explanation:
Meiosis is a type of cell division that results in four daughter cells with each having half number of chromosomes as the parent cell. It is the cell division that leads to formation of gametes to enable sexual reproduction. Division occurs twice during meiosis because before the two halves of a duplicated chromosome called sister chromatids separate, it still needs to separate homologous chromosome, which is a similar but non-identical pair of chromosome received from both parents. Hence, meiosis occurs in a two step division process i.e. Meiosis I and Meiosis II.
Meiosis II is the mitotic division of each of the haploid cells produced in meiosis I. Note that, homologous chromosomes separate in anaphase I of meiosis I, and further undergoes cytokinesis (division of cytoplasm) to produce two haploid (reduced number of chromosomes) daughter cells.
During anaphase of meiosis II, the individual chromosomes (sister chromatids) separate at the centromeres (point of attachment between two sister chromatids). The separated chromosomes are pulled apart towards each pole of the cell by the spindle fibres.

Out of the followinggiven choices;
A. parietallobe; sharper color and peripheral vision
B. occipitallobe; better spatial skills
C. prefrontalcortex; improved attention, reasoning, and cognitive control
D. temporallobe; eye-hand coordination and pincer grasp.
The answer is C.During maturation in childhood, the prefrontal cortex undergoes major development that is characterized by the growth of dendrites, reduction of synaptic andneuronal density, and an increase in white matter volume. This development is associated with the capacity of thechild to perform executive functions (meaninghigher-order cognitive control processes).
b. humoral immunity
c. cellular immunity
d. innate immunity
O Some changes to an organism have helpful effects and some have harmful
effects.
Changes to an organism's environment often have no effect on the organism.
All changes to an organism's environment are harmful.
All changes to an organism's environment are helpful.
