Answer: the one with -2 with 0.5d

Explanation:

n charging by induction, a charged object is brought near an object without touching it. The presence of the charge object induces electron movement and a polarization of the object. Then conducting pathway to ground is established and electron movement occurs between the object and the ground. During the process, the charged object is never touched to the object being charged.

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-:

10) A species is considered introduced when its transport into an area outside of its native range is human mediated. Introducti

Mnenie [13.5K]

Answer:

The introduction of new species in the new area make the specie invasive if there is no predator is present in that ecosystem because the predator helps in the controlling of the population of that invasive species. The big example of invasive species is rabbit in the Australia where rabbit become invasive when there is no predator is present in that region so they increase in population and destroy all vegetation of that region. So if there is no predator of a newly introduced species, it become invasive in future.

Part A - Independent assortment of three genes A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid

Effectus [21]

<h2>Law of independent assortment </h2>

Explanation:

There are 8 distinct phenotypes, each one has a 12,5% of appearance: Since M=solid leaves D=normal height P= smooth skin.

Recessive gene characters can only be taken in homozygous recessive mmddpp.

1. MmDdPp: M=solid leaves D=normal height P= smooth skin.

2. MmDdpp M=solid leaves D=normal height pp= peach skin.

3. MmddPp M=solid leaves dd=dwarf height P= smooth skin.

4. Mmddpp M=solid leaves dd=dwarf height pp= peach skin.

5. mmDdPp mm=mottled leaves D=normal height P= smooth skin.

6. mmDdpp mm=mottled leaves D=normal height pp= peach skin.

7. mmddPp mm=mottled leaves dd=dwarf height P= smooth skin.

8. mmddpp mm=mottled leaves dd=dwarf height pp= peach skin.

Hence,The answer is all eight possible phenotypes from the cross MmDdPp x mmddpp are equally likely, resulting in a phenotypic ratio of 1:1:1:1:1:1:1:1
