Sodium bicarbonate and digestive enzymes.
Answer:
Spores.
Explanation:
Sporulation is a type of asexual reproduction which occurs in organisms such as fungi, bacteria. In sporulation, specialized cells transformed into a hard resistant resting structure to overcome unfavourable condition. On the return of favourable conditions spores germinate to form new offspring. Sporulation is very common in fungi.

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.
Answer: option B) 0.25
Explanation:
Total population of four o’clock flowers = 8
Number of red flowers with RR phenotype = 5
Number of pink flowers with Rr phenotype = 2
Number of white flower with rr phenotype = 1
To obtain the phenotype frequency of plants with pink flowers:
put the number or Rr phenotype OVER the total population of four o'clock plants
i.e 2/8
= 0.25
Therefore, 0.25 is the answer
