Answer:
Codominance
Explanation:
So this would either be codominance or incomplete dominance. With incomplete dominance, you tend to get a whole other colour- for example crossing black and white chickens and getting a blue chicken. If you cross brown and white, and get a mix, it must be codominance because both traits are shown.
Answer:
Mechanization is used for tillage practices.
Explanation:
Mechanization is an important factor that contributes in the Green Revolution because the using machines for the softening of soil enhances root penetration in the soil as well as aeration in the soil. Mechanization involves all the machines that is used for tillage practices such as cultivator, rotavator, chisel plough etc. The use of these machines enhances production of the crop that leads to Green Revolution.
It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here are the answers. The six statements that reflect angiosperm adaptations to life on land are the following:
*Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits.
*Seeds protect and nourish plant embryos, and fruits protect the seeds.
*Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals.
*In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators.
*Flowers attract animal pollinators carrying pollen from other plants of the same species.
*Floral parts of the sporophyte protect the reduced female gametophyte from drying out and <span>from UV radiation.</span>
Answer:
The first attached figure below shows the design of an agarose gel with four sequencing reactions. The second figure presents a photo of an agarose gel, so that you can better understand how the bands are represented in this gel.
Explanation:
To view the bands of four sequencing reactions on an agarose gel, you will need to use a melted agarose gel, plastic combs suitable for that reaction and a container suitable for that type of gel. You will place the plastic combs in the container and pour all the gel into the vat and wait for the melted gel to solidify. The plastic combs will form holes in the hardened gel where the DNA samples will be placed.
Once the gel is hardened, you will remove the plastic combs and begin to apply the sequenced DNA.
The sequenced DNA samples will be mixed with a dye, usually bromophenol blue, which will allow you to visualize the bands formed on the gel. You will also apply the dye to a sample without DNA containing only the dye, which serves as a comparison for the size of the bands.
Each sample of DNA will be plated in the column of holes formed by the plastic combs. Then, this container, with the gel, will be placed in a larger container that contains a loading buffer. The larger container will be closed and an electric field will be applied that will force the DNA samples to be moved from one pole to another inside the container, in this case, the samples leave the negative pole for the positive pole.
After a few minutes, it is possible to visualize the DNA displacement and at the end of the procedure it will be possible to visualize the formation of bands as shown in the drawing and in the figure below. The size of these bands can be compared and analyzed.
