In angiosperms, pollen grains develop in the ________ and land on the _______

The peptidoglycan cell wall and the one or two membranes present also impart a three-dimensional shape to the bacterial cell. Th

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-:

3. Susceptibility to antibiotics is a trait, or inherited characteristic, of bacteria.

tatuchka [14]

Bacteria can be SUSCEPTIBLE or RESISTANT to antibiotics. Susceptible bacteria can't grow if the drug (i.e., the antibiotic) is present.

Susceptibility to antibiotics occurs when bacterial colonies can't grow in presence of the antibiotic (e.g., erythromycin).

Some antibiotic-resistant bacteria include:

Methicillin-resistant Staphylococcus aureus (it is one of the most common antibiotic-resistant bacteria)

Vancomycin-resistant Enterococcus

Which of the following activities would have the greatest impact on the amount of dirt, oil and other contaminants added to the

Ksju [112]

Urban areas are crowded places with many apartments, offices, restaurants, parking lots and shopping centers. Comparing the amount of dirt, wastages and pollutants that are released into streams and lakes by each of these sources, we can conclude that the construction of a shopping mall or parking lot contributes a lot to the addition of the wastage into the streams and lakes

A shopping mall and parking lot in itself occupies a lot of space hindering the air balance and also increasing the traffic in the area and the adjacent areas leading to this area. On the other hand , this construction accommodates hundreds of shops that discards bulks of packaging materials in the form of plastic covers, fabric, card boards and other wastages which will have to be dumped every day.

Apart from this, urban areas have major part of the land covered with roofs and roads thus making all the rain water flow into the sewer and drainages washing out chemical wastes, pet wastes and other garbages into the streams and lakes.

What kind of pyramid of numbers and pyramid of biomass will be formed in a forest with 75 tigers, 5,000 deer, and 1,00,000 trees

VikaD [51]

The correct option is A.

In the question given above, we are told that the number of trees in the ecosystem is 1,000,000; this figure far outnumber that of all the other organisms in the ecosystem. The plants are the producers in any ecosystem and they serve as sources of food for all other organisms in an ecosystem. Based on the number of trees present in this ecosystem, the pyramid of number and the pyramid of biomass will be upright, this is bcause the number of producers far outnumber the number of the consumers. A pyramid of number or a pyramid of biomass is said to be inverted if the number of producers is less than that of the consumers.
