Crop plant programs are being started which feature oil producing plants used for food as well as for fuel oils. Choose the oil producing plants from the following choices. alfalfa
peanuts
sunflowers
soybeans
cotton
flax
safflower
legumes

Answers

Crop plants that feature oilproducing plants used for food as well as for fuel oils are peanuts,sunflowers, soybeans, flax, safflower. Alfalfa has the same family as legumeswhich do not produce plenty of oil. Alfalfa functions as insectary and helpsfight insects that helps other crops such as cotton. Also, cotton cannotproduce oil.

Answer:

peanuts, sunflowers, soybeans, flax, safflower.

Explanation:

The alleles for eye color in fruit flies involves one allele that might contain the sequence CCAT. Assume that this allele produces red eyes in a fruit fly, because the allele produces a protein that makes red pigment. Assume that another allele of this gene has a slightly different sequence in the middle: CAAT, instead of CCAT.Which of the statements below is true about the alleles for eye color in fruit flies?

Which of the statements below is true about the alleles for eye color in fruit flies?

A)
The alleles for eye color produce the same phenotype.


B)
The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.


C)
Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population

Answers

Answer:

The correct answer would be B)  The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.

The amino acid sequence of any protein is determined by the codon sequence of the mRNA which is in turn determined by the nucleotide sequence of the DNA.

Thus, if the nucleotide sequence of the DNA is changed, it will result in the change of amino acid sequence of the protein.

It may result in the change of the structure as well as the function of the protein.

Thus, if the sequence in the gene is changed slightly, it would not result in the production of protein required for a red color trait.

Hence, the eye color of the fruit fly would change to white.
I'm quite sure answer B is correct :)

Suppose there are 500 units of energy available for the producer level of energy pyramid approximately how many units are in it are available in the first level consumer

Answers

Always 10% of the energy is passed on to the next trophic level and 90% is lost... mostly heat: so if the producer has 500 units of energy then the primary consumer has 10% fromm 500 = so 50 units of energy is passed on to the next trophic level.

Which scientist studied how wounds heal and proposed that cells come from preexisting cells?

Answers

Rodolf Virchow was the scientist that studied how wounds heal and proposed that cells come from preexisting cells. Rodolf Virchow was born on 13th of October in the year 1821 and died on 5th of September in the year 1902.He was a German doctor, pathologist, anthropologist, writer, editor and politician. he was a multi faceted person. He became famous because of his discoveries regarding public health. He is also regarded as the Father of modern pathology. He was German by birth. Although he failed in containing the typhus epidemic that occurred in Upper Silesia but his report was valuable in laying the foundation for public health in Germany.
