The image shows rock strata from three different regions on Earth. Identify all the layers that contain an index fossil
FrozenT [24]

The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.

The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.

By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.

What data will you collect each time you add each serum to a patient’s blood?
sattari [20]
The data you will collect is the blood phenotype.By adding serums that each contains a particular antibody such as anti-A, anti-B, or anti-D ...  to see if there's an agglutination with erythrocytes' antigen and the antibodies, proving the presence of the appropriate antigen in the blood.

This will help to confirm the blood grouping if this technique is done in parallel with the plasma test ( of Simonin-Michon).

In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.

Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.

77julia77 [94]

Answer:

Parapatric speciation  

Explanation:

There are different types of speciation. Parapatric speciation consists of new species evolving from a continuous distribution. That is, there is no physical barrier that might impede the gene flow,  in fact, it might continue during the speciation process.  

There is an environmental gradient that determines different phenotypes for different environmental conditions. One phenotype is more adapted to one of the distribution extremes than the other phenotype. In the exposed case, the environmental gradient is given by the differences in pH.

In the border between the environmental extremes, there is the primary hybrid zone, where both phenotypic forms might meet and hybridize.
