Worms use a hydrostatic skeleton to generate movement. How do they do this? Select one: The term hydrostatic simply refers to mo
cluponka [151]

Answer:

The correct answer is the third statement.

Explanation:

To hold the bodies together, to keep them incline, and to permit for movement, all the animals require support structures. There are three kinds of support systems found in animals, that is, exoskeleton, hydrostatic skeleton, and the endoskeleton. Of the mentioned support systems, the hydrostatic skeleton is used by worms for movement.  

In the worms, a fluid-filled cavity known as coelom, and the fluid known as coelomic fluid is found between the muscles and the digestive tract. This coelomic fluid works as a hydrostatic skeleton. In worms, movement takes place by contraction of muscles that compress the coelomic fluid, that is, the watery body fluid resulting in the change in body composition.

Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a s
Y_Kistochka [10]

a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.  

It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.

b) Graph is already uploaded in the below attached document.  

c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.  

d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number

Explanation:

Frequency of animals in population 1 having both alleles 1 and 3

frequency of allele 1 =0.60

frequency of allele 3= 0.25

Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100

= 0.60+0.25 X 100= 85%
