A group of cells is assayed for DNA content immediately following mitosis (G1) and is found to have an average of 8 picograms of

DNA per nucleus. How many picograms would be found at the end of S, and the end of G2 for this cell type

Answer:

16 pg at the end of S

16 pg at the end of G2

Explanation:

A cell has 8 pg of DNA per nucleus in G1.

During S phase the DNA replicates, so every nucleus will contain double the normal amount of DNA that was present in G1. Therefore, at the end of S each nucleus would have 16 pg of DNA.

During G2 the cell continues growing and preparing for mitosis, but DNA content does not change: there are still 16 pg per nucleus.

Which form of succession replaces<br> an<br> existing system after a calamity?
lina2011 [118]

Answer:

Secondary succession

Explanation:

Ecological succession is the term used to describe any series of change in the composition of an ecosystem over a particular period of time. Ecological succession is made up of two types viz: primary succession and secondary succession.

Primary succession involves the formation of a brand new ecosystem by the colonization of a barren area of land e.g bare rock, where no life existed. Secondary succession, on the other hand, is the recolonization of an area by a new set of organisms because the previously existing organisms have been wiped out by certain disasters e.g fire outbreak, hurricanes etc. In secondary succession, there is soil, which makes it possible for new organisms to sprout quickly after the calamity.

Example of secondary succession is when a fire outbreak burns the organisms in a community, allowing the root of grasses to sprout after.

Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this?
MrRissso [65]

The right answer is D.

The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.

This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.

External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.
