Answer:
the correct answer is A. a reflector that is bright in color and smooth.
The correct answer is option A, It grows healthy crops.
Because the loess soil is very fertile due to its ability to exchange cations and porosity.
Due to cation exchange capacity the plants easily absorbs nutrients from the soil and due to porosity the soil holds the water, oxygen and nutrients which is absorbed by the roots of the plants for their nourishment.
Answer:
In 1964 2.6 bales per hectare while in 2008, 380 bushels per hectare.
Explanation:
in 1964, the average corn yield was 2.6 bales per hectare which is equals to 570 kg per hectare while in 2008, the average yield of corn was 380 bushels per hectare which is equals to 9655 kg per hectare. This increase in the productivity of corn crop is due to advancement of technology, high yielding seed varieties and reduces post harvest losses. The yield of 2008 is 17 times higher than 1964.
1. DNA unzips in the nucleus.
RNA polymerase binds to the DNA sequence, separates the two strands and creates a single-stranded DNA molecule that will be transcripted.
2. Transcription occurs.
Transcription is the first step of gene expression. During this process, a gene's DNA sequence is copied and a mRNA molecule is produced.
3. mRNA moves to the ribosome
The mRNA is then transferred from the nucleus to the ribosome, the organelle that serves as a site for protein synthesis.
4. Translation occurs
Translation is the process where a mRNA sequence into the amino acid sequence of a polypeptide (protein).
5. Protein assembled at ribosome.
Translation, meaning the formation of a protein, occurs on the ribosome.
The teacher would be well advised to help students encode information about the cell using both visual and verbal forms. This is because, multiple forms of encoding increases the probability of easy retrieval. Encoding in this case involves converting the names of the cell organelles to forms that can easily be remembered.
