Answer:

The correct answer is option a. "scales".

Explanation:

The missing information of this question is the following:

"Terry catches a ray-finned fish from the ocean and notices that attached to its flank is an equally long, snakelike organism. The attached organism has no external segmentation, no scales, a round mouth surrounded by a s*cker, and two small eyes. Terry concludes it is a hagfish."

Gymnophiona is a group of amphibians characterized by having dermal scales as integumentary element. These amphibians are tetrapods and their scales are comprised of several layers of unmineralized collagenous fibers. The skeleton of the hagfish is made entirely of cartilage, therefore it is very likely that the tooth-like objects of hagfish's are made of cartilage, just like the scales of the tetrapod.

What complementary strand of DNA would be produced from the strand of DNA shown below?<br> TCG GA
mariarad [96]
Complementary pairing goes like this:

A pairs with T and 
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)

So if you have a strand that goes TCG GA then your pairing will look like this:

T A
C G
G C
G C
A T

Hope this helps!! :)

Who discovered that dna was the genetic material or transforming factor that could convert nonvirulent r-type streptococcus pneu
KatRina [158]
Discovery
               In 1928 it was discovered by Frederick Griffith in an experiment generally known as transformation.

Experiment
                 
 In his experiment he considered two strains of <em>streptococus pneumonia,</em> one was R-type which was non-virulent and cause no disease in mice, other was virulent and S-type which cause disease and at last death of mice.
This experiment was comprised of four steps which are as follow:

 Step 1:
           First he injected living strain of S into mice, after sometime mouce died.

Step 2:
          He injected living strain of R into mice, the mice alive as he did not got any disease.

Step 3:
         He injected heat killed strain of S into mice and mice remain alive.

Step 4:
           He mixed living R strain with heat killed S strain and then inject into mice. As a result the mice died.

Conclusion:
                  It was found that genetic material from heat killed S stain were transferred to living R (non-virulent) strain, as a result R become virulent and cause the death of mice.

Name the three types of population distribution, describe each, and explain the conditions that govern each.
mel-nik [20]

Answer:

Three types of population distribution:

Clumped.

Random.

Uniform.

Explanation:

1. Clumped:

This is the most common pattern of population dispersion.

organisms are clustered together in a group.

This may reflect the patchy distribution of resources in the environment.

2. Random:

This is a typical distribution where individuals do not interact strongly.

The organism has unpredictable distribution.

3. Uniform:

This is the typical environment where individuals compete with each other for scarce resources like water in the desert.

organisms are evenly spaced over the area they occupied.
