Answer:
Chemical weathering
Explanation:
The weathering of rocks by chemicals is called chemical weathering . Rainwater is naturally slightly acidic because carbon dioxide from the air dissolves in it. Minerals in rocks may react with the rainwater, causing the rock to be weathered. Some types of rock are easily weathered by chemicals.
Definition of chemical weathering: the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
Answer:
Primers should be:
3 'ACGTATGTCGCTTAGT 5'
5 'ACGTTCCAGTCAATGA 3'
Explanation:
DNA replication occurs with the need for the presence of primers that are a small sequence of nitrogenous bases that will allow the initiation of replication.
Primers are extremely important in PCR and are represented as small pieces of single-stranded DNA that specify the region of DNA that should be replicated during PCR. These primers attach to the single strand of DNA by pairing the nitrogenous bases allowing the DNA polymerase to recognize where replication begins.
Regarding the question above, the primers should be:
3 'ACGTATGTCGCTTAGT 5'
5 'ACGTTCCAGTCAATGA 3'
If you push a truck and push a car with the same force, the car will have more acceleration than the truck, because the car has less mass.
It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.
Explanation:
AuthaGraph is an approximately equal-area world map projection invented by Japanese architect Hajime Narukawa[1] in 1999.[2] The map is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining area proportions, and unfolding it onto a rectangle. The map substantially preserves sizes and shapes of all continents and oceans while it reduces distortions of their shapes, as inspired by the Dymaxion map. The projection does not have some of the major distortions of the Mercator projection, like the expansion of countries in far northern latitudes, and allows for Antarctica to be displayed accurately and in whole.[3] Triangular world maps are also possible using the same method. The name is derived from "authalic" and "graph".
When we use electronic devices in the classroom we must be:
- We have to be careful and always inspect all electrical equipment before using,
- Regularly inspect the equipment,
- Keep the power cord away from the floor and do not place objects on it-
- The ropes should not be twisted
- Attention must be paid to the electrical device while it is being used.
