Give an example of how an organism can use surface tension?

1 answer:

3 0

Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.

Surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. ... it also helps water to move up the xylem tissue of higher plants without breaking up

Answer:

The flowers and moths experienced the same allopatric speciation events during their history.

Explanation:

Co evolution may be defined as the process of the evolution of more than two species together that oppositely affects the evolution of each other. The natural selection provides the base for the co-evolution.

The co evolution generally occurs in the flowers and its pollinating species. The moth and the flower speciation represents the co evolution because both evolution are affected by each other. They have experienced the co evolution due to the allopatric speciation event and leads to teh genereation of the specific change in the characteristics.

Thus, the correct answer is option (e).

If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population

s344n2d4d5 [400]

Given:

Present population of bison = 3652

Maximum growth rate = 0.28

To find:

The population of bison after one year.

Solution:

The future population can be calculated with the help of the following formula,

$P_F=P_P\times(1+r)^n$

where $P_F$ is the future population, $P_P$ is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

$\Rightarrow P_F=3652\times(1+0.28)^1$

$\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675$

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
