Which statement is supported by the cladogram?
fgiga [73]

A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.

In this set of examples the answer is:

D) The lamprey does not have a vertical column

Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.

If a battery produced 12.6 volts, what would the current flow be for a 6 Ohm resistor
Free_Kalibri [48]

Answer:

I = 2.1 A

Explanation:

This is physics, but I will answer here either way.

First, the battery produces a voltage of 12 V in a resistor with 6 ohm, and we want the current flow (I). We need to apply the following expression:

V = R * I   (1)

This is the Ohm's law. From here we can solve for I and:

I = V/R   (2)

Now, we just need to replace the data and solve for the current:

I = 12.6 / 6

<h2>I = 2.1 A</h2>

Hope this helps

Answer:

The question as the options lacking but based on the question we can infer the ANSWER

Based on the results of the experiment we can best say that urea will disrupt the function of the certain enzyme and that when the urea is removed the enzyme regained its function.

Explanation:

Denaturation is the term used to describe urea effect on the enzymes as it inactivates it by affecting it's secondary and tertiary function. In the process it’s 3D structural conformation is altered.
