trapecia [35]
The most familiar non-vascular plants that contain simple conducting cells are Mosses. Most non vascular are bryophytes and are small in size, they lack vascular tissues and also lack true leaves, seeds, and flowers. Instead of roots, the have hair-like rhizoids that functions to anchor them to the ground and to absorb water and mineral salts from the soil. They are three types, mosses, hornworts and liverworts.

A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a ________________ protein.
djverab [1.8K]

A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a <u>dimeric</u> protein.

  • Isozyme is a multimeric forms of enzyme having similar specificity of the substrate but differences in kinetics and molecular weights of the enzymes.
  • The banding patterns of isozyme observed from electrophoresis is related to the genetic conditions in which different combination of polypeptide chains exhibited under the mendelian principles.
  • Hence with the intensity of 1:2:1 ratio, three banded phenotypes are formed having two homomeric and one heteromeric form from the dimeric protein in both multiple alleles at single loci and multiple /single allele at multiple loci.

Use the drop-down menus to decide if an example of similar traits is likely a homologous structure or an analogous structure.
snow_tiger [21]

Answer:

- Bird wings and dragonfly wings are both used for flight: Analogous structure

- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure  

- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure  

- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure  

Explanation:

Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.

Electricity is the movement of free electrons from a0 charged areas to a1 charged areas.
klasskru [66]

The answer is; negative…positive

In a closed circuit, electrons move from the negative  node to the positive node. Electric current, on the other hand, flows from the positive node to the negative node. The flow of electrons and electric current is measured in amperes (A).
