All arachnids are predators.

Arachnids have two body sections: a prosoma (the head section) and an abdomen.

They usually hunt other insects, or creatures of their own kind.

Evolutionary relationships between organisms are determined by.
Georgia [21]

Answer:

hope you like it

Explanation:

A molecular clock determines evolutionary relatedness by examining how many mutations or random changes in DNA, there are between two organisms. When we map the relatedness of different organisms, we are creating a phylogenetic tree. At some point, all organisms that are alive today shared a common ancestor.

Which statement best explains how the rock shown in this photo was deformed​
meriva

Answer:

B. Stress caused by forces that stretch an area of the crust made the rock to break

Explanation:

From the picture inserted to this problem, we see a unit that has been severely fractured.

Fracturing results from the brittle deformation of a rock under applied stress.

  • Rock fracturing results in the formation of joints and faults.
  • We can obviously see different sets of joint sets on the body of the rock in the picture attacked.
  • Also, a prominent fault which resembles an extensional fault can also be seen.
  • Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.
