Answer:
27.5
Explanation:
Divide 75 by 6. You get 12.5. Multiply 12.5 by 2.2 (when converting kilo to pound, you multiply by 2.2) Then, you'll get 27.5. The answer is 27.5 pounds/lbs.
Nearsightedness is the answer.
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer: metagenomics
Explanation:
Metagenomics is the study of the collective genome of the microorganisms obtain from the environment. The study can provide details of the microbial diversity and ecology for a particular environment. It allows the identification of the specific microbial species from the mixture of genomic samples. The metagenomics is useful in solving the problems related to other fields such as medicine, agriculture, engineering and ecology.
Answer:
The correct answer is option C, that is, in the mother in meiosis II.
Explanation:
A nondisjunction in meiosis I produce all the aneuploid gametes, while nondisjunction at meiosis II produces 50 percent aneuploid gametes and the 50 percent normal gametes comprising haploid number of chromosomes.
As it is mentioned that one of the brothers possess normal number of chromosomes (46), the mother encounters nondisjunction at meiosis II resulting in the formation of one n+1 gamete exhibiting two copies of X chromosome. Fertilization of this n+1 gamete with sperm results in the creation of zygote (47, XXY).
