Controlled population growth.
Explanation:
US is a highly developed country and it has expansive infrastructure and highly mechanized agricultural equipments. So first option is not a choice. Second, access to chemical fertilizers and pesticides in a country with such advanced agriculture infrastructure is very easy. Third US is well known for using GM crops.
US does not have a controlled population growth because if not the birth rate then migration of people to US is a major concern for that country. Thus, this will be a correct choice for the given question.
Answer: Option A
The primary function of DNA polymerase is to add nucleotides to the growing daughter strands.
Explanation:
DNA polymerase is an enzyme that synthesis DNA and its main function is to make DNA from nucleotides which is the building block of DNA. It is essential for DNA replication and work in pairs by creating identical DNA strands from the original DNA molecule. DNA copies are created by pairing the nucleotides to each bases present in the DNA molecule.The bases are thymine, cytostine,guanine, and adenine, the pairing occur with any of the above combinations forming two pairs respectively.
Answer:
In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
GG x bb = Gb, Gb, Gb and Gb F1 generation
grey body heterozygous offspring 4:0
Gb x Gb= GG, Gb, Gb, and bb F2 generation
3:1 three grey body fly and one black body fly
Explanation:
The correct answer is:
CO2 diffuses passively out of the cell.
O2 in respiration is converted to water. O2 diffuses in to the cell.
Explanation:
Cellular respiration is the chemical reaction in which glucose and oxygen are converted into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to change biochemical energy from nutrients into adenosine triphosphate and then discharge waste products.
Answer:
The correct answer is - The amygdala
Explanation:
The amygdala is the part of the brain that is found in the medial temporal lobe of the brain. It is an almond-shaped structure of neurons. The amygdala is an essential region of the brain that has a major role in processing emotions such as aggression and others. It is the region of the limbic system that presents both sides of the brain.
Thus, the correct answer is - the amygdala.
