Southern blot
agarose gel electrophoresis
polymerase chain reaction
Answer:
A. Polyacrylamide gel electrophoresis (PAGE)
Explanation:
Protein fragments of different size can be separated by gel electrophoresis method. Different proteins are made up of different number of amino acids and so the chain length vary i.e. the size of different proteins may vary. Also different proteins may have different charges due to difference in the type of amino acids present in them.
Generally for separating the protein fragments according to their size polyacrylamide gel is used. Foe this proteins are first given the heat treatment and treated with SDS for unfolding the protein. SDS is a detergent that imparts negative charge to protein. During electrophoresis, under the electric field the separation would be only due to size but not charge as all the proteins are treated with SDS and thus have same negative charge. This method is called SDS-PAGE. Under the electric field, small protein fragments will move fast through the pores compared to large fragments leading to their separation.
If two proteins are of same size then to separate them wither agarose gel electrophoresis is used or isoelectric focusing.

3. phylogenetic
4. morphological and phylogenetic
5. biological, morphological and phylogenetic
Characteristics:
1) accommodates asexual reproduction
2) not applicable for extinct species
3) relies on similarities of structures
4) used by scientists in classification
5) species acceptance criteria can be subjective
6) based on evolutionary history
Answer:
Biological species concept defines species as individual in a population that can interbreed and produce viable offsprings. Therefore Biological species concept is not applicable for extinct species
Morphological means in relation to structure therefore, this concept relies on similarity of structure to classify species.
Phylogenetic refers to members having the same ancestor. It classifies species according to common ancestry. Hence it will be based on evolutionary history.
Morphological and phylogenetic- Will accommodate asexual reproduction and species acceptance criteria can be subjective.
Biological, morphological and phylogenetic-Together they are used by scientists in classification
In the context of biological species, it does not support asexual reproduction and is not for extinct species. Morphological species, rely on structure similarities, are used for classification, and have subjective species acceptance. Phylogenetic species are based on evolutionary history, supports asexual reproduction, and has subjective species acceptance criteria.
The three significant concepts of species include the Biological species concept, Phylogenetic species concept, and Morphological species concept.
1) Biological species - This concept does not accommodate asexual reproduction (2) and is not applicable to extinct species (2).
2) Morphological species (or morphospecies) - This concept relies on similarities of structures (3), is used by scientists in classification (4) and the species acceptance criteria can be subjective (5).
3) Phylogenetic species - This concept is based on evolutionary history (6), can accommodate asexual reproduction (1) and the species acceptance criteria can be subjective (5).
The morphological and phylogenetic concepts are used by scientists in classification (4) and their species acceptance criteria can be subjective (5).
All three concepts - biological, morphological, and phylogenetic - are all considered in the broader understanding and definition of species.

its a drag and drop question to its right location.
Answer:
Physical Layers:
- Crust
- Mantle
Compositional Layers:
- Asthenosphere
- Mesosphere
Explanation:
Physical Layers refer to the layers of the Earth based on their physical properties such as their state (solid or semi-solid) and how they behave. The two primary physical layers are the Crust and Mantle.
- Crust: The Earth's Crust is the outermost layer, which includes the solid ground we walk on. It is relatively thin compared to the other layers and is where we find the continents and ocean floors.
- Mantle: The Mantle lies beneath the crust and is semi-solid, extending to a depth of about 2,900 kilometers (1,800 miles). It's responsible for the convective movement of the Earth's tectonic plates.
Compositional Layers, on the other hand, are based on the chemical composition of the Earth's interior. They include:
- Asthenosphere: The Asthenosphere is part of the upper mantle and is composed of partially molten rock. It's semi-fluid, allowing for the movement of tectonic plates. This is crucial for plate tectonics and the Earth's surface dynamics.
- Mesosphere: The Mesosphere is not typically considered a distinct compositional layer in the Earth, but rather part of the lower mantle. It consists of solid rock that behaves plastically, allowing for convection currents to occur deep within the Earth.

Pollution in air, water and soil is the result of these changes, Eventually, causing harm and (13) ______ to living things.
please kindly answer these.
Answer:
Air pollution can significantly hurt the quality of soil and water resources. When we pollute our air, we are also polluting the precipitation that falls into water bodies and soils.
