lom? What (if anything) can be inferred about whether the common ancestor of each of the three major bilaterian clades had a true coelom? We cannot infer anything about the status of the ancestor of the Lophotrochozoa, Ecdysozoa, or Deuterostomia. The common ancestor of each of the three clades -- Lophotrochozoa, Deuterostomia, and Ecdysozoa -- had a true coelom. The common ancestor of the Lophotrochozoa and the Deuterostomia had a true coelom, but we cannot infer anything about the ancestor of the Ecdysozoa. The common ancestor of the Deuterostomia had a true coelom, but we cannot infer anything about the ancestor of the Lophotrochozoa or the Ecdysozoa.

A paragraph on the 3 forms of energy involved in a muscle contraction
irga5000 [103]
There are three types of energy involved in a muscle's contraction. There is metabolism, catabolism, and anabolism. Metabolism is the events that are carried out in the human body to create energy and other things needed for activity. Catabolism is the process during the organic matter is broken down and the energy is released, it takes place during increased movement. Anabolism is the energy-consuming process that substances are created, it takes place when there is little movement. All three of these work to gather in muscle contraction.

Ostrovityanka [42]

Answer:

B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains

Explanation:

  • The Appalachian mountains form a system of mountains in eastern North America and are older than rocky mountains as they were formed 480 million years ago and are similar to those of the alps. They form a barrier to the east to the west.
  • They extend to southeast Canada and form zones of 300 miles wide. They form the mountain ranges surrounding hills and the dissected plateaus forming at an elevation of 6,684 meters from the sea level. <u>Whereas the rocky mountains are younger and have an elevation of 4,401 meters.</u>

EleoNora [17]

Answer:

Option (B).

Explanation:

The relationship between closely related species can be studied by their evolutionary tree. The two species are closely related if they have similar characteristics and nucleotide sequence.

Species A has the DNA sequence TAGCTTAGGGACGG  whereas species B has the DNA sequence TACCTTAGGGACGG. These two species have identical nucleotide sequence with minor differences. Hence, these two species are closely related with each other.

Thus, the correct answer is option (B).
