The average female Atlantic cod (Gadus morhua) produces two million eggs in a single spawning. How does this relate to natural s
Alex Ar [27]
This is a typical example of R selection life strategy. These species, including the Atlantic cod, produce a large number of offspring with a low chance of surviving to adulthood. This strategy is particularly successful in environments that are unstable. The main advantage of this strategy in changing environments is that the ''cost'' of making offspring is very low, so you the species can produce large numbers offspring, ensuring that at least some of them will survive into adulthood and continue the species.
Natural selection, in this case, favors the individuals that are able to adapt the fastest to the changing conditions.

A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied t
andreev551 [17]

5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

<h3>Given</h3>

Mass of oxygen at room temperature =500.0 ml

Volume of pressure = 50 atm pressure.

The gas to a volume = 150.0 ml

<h3>Explanation</h3>

The volume decreases by the factor = 500.0 mL / 150.0 mL

                                                             = 10 / 3

The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to

P_{final} = \frac{10}{3} * 1.50 atm

          = 5.00 atm

So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

Mendel investigates stem length, or height in pea plants what if he had investigated human height instead why would his results
WINSTONCH [101]

Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).

On the other hand, a Mendelian trait is controlled by a single locus.
