Sonja [21]

1. taxonomic category within a kingdom-phylum

This taxonomic category is at level below Kingdom and above Class (e.g Arthropoda, Chordata, Mollusca)

2. plant that lives on decaying organic matter-saprophyte

Saprotrophic plants or saprophytes use saprotrophic nutrition meaning that have extracellular digestion to process death organic matter.

3. break down of complex molecules into simpler ones- fermentation

Fermentation is a metabolic process that breaks down organic substrates in order to obtain energy. These processes are performed without the presence of oxygen (anaerobic processes).

4. multi-nucleated thread-like structures of fungi hyphae

This is one of the basic structural unit of fungi-long, filamentous structure that can form network-micelium. It is used for vegetative reproduction.

5. mycelia responsible for obtaining food from non-living organic material rhizoids

Rhizodis are unicellular or multicellular stuctures (branching hyphae) found in fungi that are similar to root hairs of plants. These structures are involved in saprotrophic nutrition of fungi.

6. asexual reproduction of yeast budding

Budding is a type of asexual reproduction in which a new organism develops from some generative anatomical part of the parent organism.

7. a group of hyphae mycelia

Mycelum is fungi’s vegetative body that consists of network of branching hyphae.

8. reproductive cells which can tolerate bad conditions spores

Spores are reproductive structure, part of the fungi life cycle, that can be involved in sexual or asexual reproduction, vary in structure that are formed in. Spores are usually haploid and unicellular.

9. structures which house the reproductive formation fruiting

Fruit is a structure in flowering plants that contains seed and it is responsible for seed dispersal and nutrition.

10. mutually positive relationship between two species symbiosis

Symbiosis is biological interaction between two species that can be mutualistic, commensalistic, or parasitic. More specifically, symbiosis refers to positive interaction for both members of it.

11. plant or animal which supports a parasite host

Parasitic relationship between species is the one in which organism (the parasite), lives on or in another organism (host).This relationship is positive for parasite but negative for the host.

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-:

Nuetrik [128]

Answer:

Angiotensin II and ADH (in high doses) ___Increases_________ peripheral resistance and blood pressure; and angiotensin II, aldosterone, and ADH ___Decreases_________ urine output to help maintain blood volume and blood pressure. ANP stimulates__volume receptors_____ , which decreases _peripheral resistance__________ and increases _in porasium serum_______ , which decreases blood ____volume________ . The net effect is a decrease in blood ____Pressure________

Explanation:

Angiotensin II is a powerful vasoconstrictor, greatly increasing blood pressure. It also stimulates the release of ADH and aldosterone, a hormone produced by the adrenal cortex. Aldosterone increases the reabsorption of sodium into the blood by the kidneys.

Atrial natriuretic peptide (ANP) is released in response to increased stretch in atria as a consequence of high blood volume and high blood pressure. The effect of ANP is to decrease both peripheral resistance and blood volume with a resultant decrease in blood pressure to within normal homeostatic limits.
