Answer: C. meiosis produces sex cells that are joined during sexual reproduction to produce offspring
Explanation:
Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.
The statement " If you do not follow the instructions for mixing,.....you are not complying with federal law" is TRUE
Disinfecting products are used to prevent and fight against disease causing organisms but they can be harmful to individuals when applied or used wrongly on the wrong surface or if they come in direct contact with human skin for a prolonged period.
The quantity of chemicals and proportion of chemicals used during the production of disinfecting products should follow a particular guideline as established by regulatory authorities. and if not followed would be violating federal law.
Hence we can conclude that the statement If you do not follow the instructions for mixing,..... is TRUE

The ecosystem is the lowest level of environmental complexity that includes living and nonliving factors. if that's what your looking for.
Answer:
→presence of lot of mucus which blocked the respiratory pathways.
→narrowing of air ways due to inflammation of the epithelial limning.
→inability of the alveolar walls to expel air due to loss of elasticity
Explanation:
When an individual experiences difficulty with breathing,coughed with thick sputum produced,and accompanied with wheezing sounds, there is likelihood of the blockage or obstruction of the respiratory passages to the lungs, which traps air in the lungs and prevents its removal.This condition is called COPD. It is the combination of some pulmonary disease mostly-emphysema and chronic bronchitis, and worsen with time.
Emphysema is the loss of elasticity of the alveolar due to damage to the Elastin tissues(usually by nicotine, tar, in cigarette) which allows the sacs to expand and contracts.Sacs are filled air , but the trapped air can not escape , therefore the lung expands,creating pain for the subject.
The chronic bronchitis is the inflammation of the epithelial lining, which continue to irritate the bronchi, which stimulate immune response and therefore mucus production. it is this mucus that blocked the bronchi given difficulties with breathing (shortness of breath)giving wheezing sounds.
<u>Good lifestyle,intake of medication are measures to cure and prevent this.</u>
