Answer:
All of the characters are present in a bacteria.
Explanation:
i)Bacterial cell wall is composed of petidoglycans which is made up of sugar and amino acid molecules that helps in protecting the bacteria from different antibiotics like penicillin etc.
ii)Bacteria lack many cell organelles that are found in eukaryotic organisms like nucleus,mitochondria, golgi body, ER,chloroplast etc.
iii)Bacterial plasma membrane mainly formed by amphiphilic lipids which contain glycerol, phospholipids, that are composed of two fatty acids and a phosphate group with variable head.
iv)Bacteria require proper environment like food,moisture,temperature for their growth and development.The ideal temperature is 40-122°C
Answer:
The amylase had the higher absorbance with a pH of 7.
Explanation:
Enzyme activity values are given by the spectrophotometric method. The constant temperature is maintained in order to evaluate the pH independent effect. The absorbance is then measured at various pHs and the one that corresponds to the greatest absorbance is the pH at which the enzyme has its peak activity. So pH 7 is the optimal pH condition.
Answer: floodplains are usually very fertile agricultural areas. Floods carry nutrient-rich silt and sediment, and distribute it across a wide area.
