The correct answer is B. Sensitive period
Explanation:
In development, the sensitive period refers to a lapse of time in which organisms are more susceptible or receptive to stimuli and therefore during this time there can be great advances in development. Additionally, different from critical periods sensitive periods do not imply irreversible consequence if the stimuli are not presented. For example, in human beings from birth to the age of 6 years, children are more receptive to learn and acquire certain skills such as learning a new language if exposed to it and therefore this can be considered as a sensitive period. Considering this, it can be concluded the definition presented refers to the Sensitive period.
Answer:
c. Spindle fibers
Explanation:
In eukaryotic cells, the centrioles are small sets of microtubules composed of tubulin proteins. Moreover, in animal cells, a centrosome is an organelle localized near the nucleus which contains a pair of centrioles. These organelles (centrosomes) are referred to as microtubule-organizing centers. During Anaphase, centrioles move to opposite sides in the cell in order to organize the spindle fibers and separate the chromosomes during cell division.
Answer:
order of least damaging is b, a, c and d
Explanation:
The 4 kinds of point mutations here present different consequences after a change of a single base pair. The silent point mutation is the least damaging because the alteration of the nucleotide does not implies on a different codon. Missense and nonsense point mutations will imply on a change of a entire different codon and a change of a entire codon to a stop codon, respectively. The missense could be a less aggressive mutation than a nonsense because the codon change may affect only in a small proportion of the entire protein, but the nonsense can be very aggressive by making the protein smaller than it is. The frameshift can cause severe modifications on the whole final protein because almost every codon might code for a different aminoacid leading to a whole new protein.
