Biotechnology is used in a variety of areas from agriculture to pharmaceuticals to fuels.How is the use of biotechnology in agriculture beneficial to the environment?
Genetically altered crops are unable to reproduce.
Genetically altered crops produce less carbon dioxide.
Genetically altered crops require less pesticide.
Genetically altered crops are more delicious.

Answers

Answer 1

Answer:

The correct answer is (C) Genetically modified crops requires less pesticide.

The genetically modified crops are designed in such a way that it requires less amount of pesticide. These plants contain the gene resistant for pest. These plants are often called as Bt plants. Almost 40% of the maize crops used in United States are genetically modified crops. All these are pest resistant and require very small amount of pesticide to kill some of the pest.

Answer 2

Answer: Genetically altered crops require less pesticide as their DNA can be reconstructed to create insect resistance or other resistances to the climate or poor soul quality.

Answers

For a given species an increased evolutionary rate would cause a decrease in mutation rate.
>Three factors that would increase the rate of evolution would be the intensity of directional selection, an increase in the birth rate, hence an increase in the number of possible beneficial mutations, and an increase in the population size.>There are many limiting factors that might control the evolutionary rate of change. Physical or biological changes influencing the environment can play a major role in the rate of evolutionary change.

15 POINTS!! Which of the following is the correct order for the nitrogen cycle beginning with nitrogen gas?

a nitrogen gas - nitrate — ammonium - nitrite
b nitrogen gas - nitrite -nitrate - ammonium
C nitrogen gas - ammonium - nitrite - nitrate
d nitrogen gas - ammonium - nitrate - nitrite

Answers

The nitrogen cycle which is converted to an intermediate, is generally used by the organism at certain levels, hence option c nitrogen gas, ammonium, nitrite, nitrate is correct.

What is the nitrogen cycle?

The nitrogen cycle in the biogeochemical cycle converts nitrogen into various chemical intermediates as it cycles into the air, terrestrial, and marine environments.

The nitrogen conversion processes occur through both biological and physical mechanisms. Fixation, ammonification, the first two steps, nitrification, and denitrification are all important processes in the nitrogen cycle.

The bulk of the Earth's atmosphere contains (78%) majorly composed of atmospheric nitrogen, make the primary source of nitrogen.

Therefore, option c begins with nitrogen gas, ammonium, nitrite, and nitrate in the correct order.

Chemistry is important in biology because both sciences focus study on _____.

Answers

Answer:

Chemical reactions.

Explanation:

Chemistry is the study of different chemicals and their chemical reaction. Every day one uses the things all are made up of chemicals. All the chemicals and matters are the result of the chemical reaction.

For example, water is a compound which is formed by the hydrogen bond between the 2 hydrogens and one oxygen molecule. The properties of water are also different from individual hydrogen and oxygen molecules.

Our body is also made up of 70% to 80 % of water. All the metabolic reaction need water. Similarly, all matters are made up of chemicals. Chemical reactions happen when an organism eat, breathe, division of cell occur, etc. Every physiological process includes a chemical reaction.

The living organisms consist of some biomolecules, carbon, hydrogen, oxygen, nitrogen. All are playing a vital role in different biochemical reactions. Biochemistry is the branch of study in biology which deals with the role of chemistry in biology.

Chemistry and biology are important for studying the different chemical reactions occur in the living organisms. Proteins, carbohydrates, lipids, are all formed due to the chemical reaction and these are known as biomolecules.
