Answer:
Meiosis is a reduction division of diploid cells.(2n) Chromosomes numbers are reduced with each successive division stages  of meiosis 1 and 2, to haploid(n).
Cats  have  38 diploid  somatic (body)chromosome (2n) in the somatic cells  and are reduced to 19  new   varied haploid cells (n) of chromosomes in the gametes.
In cats, as in other mammals, during spermatogenesis in (seminiferous tublule of testis) and oegensis(in the ovaries);<u>meiotic  reduction division</u> reduced the diploid  somatic chromosomes to haploid chromosomes  in  sex gametes.
 Therefore 38 chromosomes will be in  the somatic chromosomes, while the sex gametes, with double-helical molecules of DNA, at the end of meiosis II will  have 19 chromosomes, half of the somatic chromosomes.

Answer:
The correct answer is: Mucus membrane.
Explanation:
- The lining of the epithelial tissue forming the mucus membrane contains some specialised cells which are called the Goblet cells.
- These cells secrete a slippery substance called the Mucus.
- The Mucus is a dense, aqueous and slippery substance that is composed of anti-microbial enzymes like lysosyme, immunoglobulins (antibodies) and glycoproteins like mucins.
- The mucus secreting cells line the internal tracts of the body that come into contact with outside environment, like the respiratory tract, alimentary canal, urino-genital tract.
- If any microbial pathogen gain access into any of these tracts the lysosyme in the mucus causes the microbial cells to undergo lysis, hence killed. 
- The immunoglobulins, on recognising a pathogen, activate the immune cells of the body to fight against the intruding pathogen.
 
        
             
        
        
        
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
hope this helps ^^
