During an interphase lasting 23 hours the S stage takes average 8.0 hours.What is the percentage of interphase is taken up by S
Alik [6]

The right answer is 34.78%

The interphase is the period of the cell cycle that the cell transcribes its genes and the chromosomes are duplicated. It can be subdivided into several phases:

* phase G1

* phase S: during which the chromosomal material is doubled by DNA replication. This is called chromosome duplication.

* phase G2.

Phase G1 is the longest phase of the interphase (its duration depends on the type of cell), followed by phase S, then phase G2.

To calculate the proportion of phase S in the interphase simply make the division:

phase duration S / interphase duration = 8/23 = 0.3478 (in percentage that is 34.78% (0.3478*100)).

the “good genes hypothesis” proposes that people with physical qualities like averageness, symmetry, sex prototypicality, and yo
navik [9.2K]

The correct answer is 1) Evolutionary

Explanation:

The "good genes hypothesis" argues traits of the opposite sex that are considered as positive or attractive reflect evolutionary traits and therefore are indicators of a better-quality mate. Indeed, this theory argues attraction is connected to better chances of survival or better chances to reproduce. This belongs to the evolutionary approach in psychology because these "attractive" traits are the result of evolution because only the "fittest" individuals reproduce and their genes prevail over time.

Explain how introducing a new species to an ecosystem or losing an entire population can impact the ecosystem.
AlladinOne [14]

Answer:

The ecosytsem has a very fine balance. Each species is dependant on one another for food and population control. Introducing a new species such as the Cane Toad which has been introduced into Australia and Flordia and are extrmely invasive completly wipping out populations of Native species and are a huge problem. If you lose a population such as the wolves in yellow stone species such as elk will actually suffer from starvation and other issues due to lack of food etc because the wolves were not there for population control. But in some cases such as the wolves who were added back into Yellow stone it had a huge positive impact on species/populations.
