Answer: Industrial fixation of Nitrogen

Explanation:

Industrial fixation of nitrogen has enabled humans to be able to make nitrogen fertilizers that are able to supply plants with much needed nitrogen that they need to survive. Indeed it is said that up to 40% of the nitrogen taken up by plants is from artificial sources.

The world's population might not be what it is today without this invention because it was able to return nitrogen to the soil at a time when humans needed it because we had been intensively farming land which led to it losing nutrients.

More nitrogen allowed us to keep farming and keep feeding the population which then exploded.

Combining dna from different organisms or different locations of a given genome that would not normally be found in nature is th

aalyn [17]

Combining DNA from different sources is the definition of Recombinant DNA or rDNA. This is what is more commonly referred to as genetic engineering. The applications for this technology are vast, but very expensive. The use of Recombinant DNA has seen applications in agriculture where plants are given immunity to certain diseases or molds from another plant which is resistant or where human DNA is combined with forms of bacteria to produce a more natural insulin for people who are diabetic.

Carbohydrates are typically broken down to A. glucose, the molecule used as the energy source in cells. B. maltose, the molecule

mario62 [17]

Answer:

The correct answer would be A, Glucose, the molecule used as the energy source in cells.

Explanation:

Carbohydrates are one of some important and main sources of energy in the human body. Main sources of energy are Carbohydrates, Fats, Proteins and Vitamins and Minerals, etc. Carbohydrates are broken down in the body as glucose which are then converted into energy which is used by the cells of the body to take out many tasks of human body like growth, movements, reproduction, digestion, etc. Without energy, the body of living things cannot do routine task. So when body eats carbohydrates, they are broken down into glucose which is further transformed into energy and is used by the human body.

A grow seeded purple flowered heterozygous plant (YyPp) is crossed with a green seeded, white flower plant (yypp). What is the p

vredina [299]

Question:

A yellow seeded, purple-flowered heterozygous plant (YyPp) is crossed with a green seeded, white-flowered plant (yypp).

(Y = yellow seed allele; y = green seed allele; P = purple flower allele; p = white flower allele)

What is the probability that an offspring of this cross produces plants with green seeds and white flowers? Assume the traits assort independently.

Answer:

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25

Explanation:

Available data:

Y = yellow seed allele; Dominant
y = green seed allele; Recessive
P = purple flower allele; Dominant

p = white flower allele; Recessive
the traits assort independently

Cross: A yellow seeded, purple-flowered heterozygous plant with a green seeded, white-flowered plant

Parentals) YyPp x yypp

Gametes) YP, Yp, yP, yp yp, yp, yp, yp

Punnett square)

YP Yp yP yp

yp YyPp Yypp yyPp yypp

F1) 4/16 = 1/4 = 25% YyPp, Yellow seeds and Purple flowers

4/16 = 1/4 = 25% Yypp, Yellow seeds and white flowers

4/16 = 14 = 25% yyPp, green seeds and purple flowers

4/16 = 1/4 = 25% yypp, green seeds and white flowers.

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25
