What happens if the body is unable to maintain its blood glucose levels?
Answer:
Explanation:
Without insulin, cells are unable to use glucose as fuel and they will start malfunctioning. Extra glucose that is not used by the cells will be converted and stored as fat so it can be used to provide energy when glucose levels are too low.

Why do fats have higher caloric value than other organic molecules?
Fats have higher calorific value. Fats have high energy than other molecules.
What is high calorific value?Calorific value, which is measured by measuring the heat generated by the full combustion of a particular quantity of a substance, is nothing more than the energy present in a fuel or food. Currently, this is typically given as joules per kilogram.
A device called a calorimeter is used to calculate calorific value. In order to determine how much heat was generated during combustion, a predetermined amount of the object being investigated is burned under carefully controlled conditions.
Therefore, Fats have higher calorific value. Fats have high energy than other molecules.

The peptidoglycan cell wall and the one or two membranes present also impart a three-dimensional shape to the bacterial cell. The overall shape and arrangement of bacteria are genetically determined, so that each genus of bacteria has a characteristic shape (round, rod, spiral, etc.) and arrangements of the growing cell population (individual cells, chains of cells, or clustered cells).Bin 1 - Image of a single round bacterium.Bin 2 - Image of a single rod-shaped bacterium.Bin 3 - Image of a cluster of round bacteria.Bin 4 - Image of a string of rod-shaped bacteria.Bin 5 - Image of a comma-shaped bacterium.Bin 6 - Image of a corkscrew-shaped bacterium.Drag the descriptive terms to the pictured bacterial shapes.
Answer:
The following images of different types of bacteria are attached here-
1- Single round bacterium- Cocci
2- Single rod-shaped bacterium- Bacilli
3- Cluster of round bacteria - Staphylococci
4- String of rod-shaped bacteria- Streptobacillus
5- Comma-shaped bacterium- Vibrio
6- Corkscrew-shaped bacterium- Spirillium
Explanation:
1- Single round bacterium- Cocci -Any bacterium or archaeon that has a circular, ovoid, or usually round shape is a coccus (plural cocci). Cocci may develop in pairs, chains, or clusters during cell division, depending on their orientation and attachment. Many cocci bacteria do not have flagella and are non-motile, in contrast to many bacilli-shaped bacteria.
2- Single rod-shaped bacterium- Bacilli -A rod-shape bacterium or archaeon is a bacillus (plural bacilli), or bacilliform bacterium. In several different taxonomic classes, bacilli are found. Bacilli typically divide and are solitary in the same plane, but can combine to form diplobacilli, streptobacilli, and palisades.[2]
Diplobacilli: Two bacilli with each other arranged side by side.
Streptobacilli: Arranged bacilli in chains.
Coccobacillus: Coccus-like and oval (circular-shaped bacterium).
3- Cluster of round bacteria - Staphylococci - In the family Staphylococcaceae from the order Bacillales, Staphylococcus is a genus of Gram-positive bacteria. They appear spherical (cocci) under the microscope, and form into grape-like clusters. The species Staphylococcus are facultative anaerobic organisms (both aerobically and anaerobically capable of growth)
4- String of rod-shaped bacteria- Streptobacillus -Streptobacillus is a genus of fastidious gram-negative microaerophilic bacteria, an uncommon disease that develops in culture as rods in chains.t and can be caused by two forms of bacteria, Spirillum minus and Streptobacillus moniliformis.
5- Comma-shaped bacterium- Vibrio -Vibrio is a genus of Gram-negative bacteria with a curved-rod (comma) shape, which can cause foodborne infection in several animals, typically associated with consuming undercooked seafood. Vibrio species, usually found in salt water, are optional anaerobes that test positive for oxidase and do not form spores.
6- Corkscrew-shaped bacterium- Spirillium -Spirillum, a genus of spiral-shaped bacteria of the Spirillaceae family, aquatic with the exception of one species (S. minus) causing a form of human rat-bite fever. For any of the corkscrew-like animals, the name spirillum is used commonly.
Microbiologically, Spirillum is characterized as a gram-negative, motile helical cell with whiplike flagella tufts at each end.
hence, the images of the different bacteria are attached below-:
