this are the five-kingdom of system

Monera (includes Eubacteria and Archeobacteria,

Protista,Fungi,

Plantae,

Animalia.

What shape are all diatomic molecules?

Diatomic molecules have 2 atoms combined. The way they line up is determined by the desire to keep each atom as far away as possible from all the other electrons in the molecule apart from those being shared. The only way to do this is to be a linear molecule, so the atoms are side by side.

What is the relative size of amoeba?

30 feet wide on the sea floor

that is an amoeba from Dungeons and Dragons.

there is Gromia sphaerica the size of a grape, and Pelomyxa palustris that can reach 5 millimeters across. but usually they are smaller than 0.1mm.

What is an amoebas habitat?

The Habitat of Amoeba is under water, i.e lakes, ponds. Some say that Amoeba Is its own habitat because its all just a bunch of Amoebas stuck together. I suggest using both of these theories, in whatever case you are looking up the following question. With love, and peace, - The 12 year old, anonymous

What cells act as the gametes in the conjugation of spirogyra or paramecium?

In the conjugation of Spirogyra, the gametes are the specialized reproductive cells called gametangia. In Paramecium, the gametes are the micronuclei, which undergo meiosis to form haploid nuclei for genetic exchange during conjugation.

How do paramecium get oxygen?

Paramecium obtain oxygen through diffusion across their cell membrane. This process allows oxygen to pass from the surrounding water into the cell where it is used for cellular respiration to produce energy.

What is the Process in which paramecium exchange DNA?

Paramecium exchange DNA through a process called conjugation. During conjugation, two paramecia come together and form a cytoplasmic bridge through which genetic material is exchanged. This genetic exchange results in increased genetic diversity among the paramecia.

How the paramecium reproduces?

Paramecium reproduces asexually through binary fission, where the cell divides into two identical daughter cells. Additionally, they can also undergo sexual reproduction through a process called conjugation, where genetic material is exchanged between two individuals to increase genetic diversity.

Can move like amoebas and reproduce like fungi?

Organisms that can move like amoebas and reproduce like fungi include slime molds. Slime molds are single-celled organisms that can join together to form multicellular structures when reproducing. They move by extending their cytoplasmic projections, known as pseudopodia, similar to how amoebas move.

Explain why the kingdom protista is called the Junk Drawer?

The kingdom Protista is sometimes referred to as the "junk drawer" because it contains a diverse group of organisms that do not fit neatly into the other kingdoms of life (Animalia, Plantae, Fungi). Protists vary greatly in terms of their characteristics, habitats, and evolutionary history, making them challenging to categorize. This diversity has led to the informal comparison of the Protista kingdom to a miscellaneous drawer where things that don't quite fit anywhere else are placed.

What is a protists niche?

Protists occupy various niches in ecosystems, including being primary producers through photosynthesis, decomposers breaking down dead organic matter, and serving as food sources for other organisms. They can also act as parasites or mutualistic symbionts with other organisms, demonstrating their adaptability and diversity in ecological roles.

Protists are simple animals made up of?

Protists are made up of very large, diverse group of organisms, including the plant-like protists (algae), fungi-like protists, and the animal-like protists (protozoans). They are all eukaryotic, and most are unicellular.

What elements exists as a diatomic molecule?

There are seven elements that form diatomic molecules they are:

hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2).

Compare the features shared by an amoeba and a specialized cell in the human defense system?

Both amoebas and specialized cells in the human defense system (such as macrophages) are capable of phagocytosis, the process of engulfing and destroying foreign particles. They also both have the ability to move and change shape in order to reach their target. Additionally, they both play a key role in the body's immune response and defense against pathogens.

Was linda Henry in cell block h?

Yes, Linda Henry appeared in the TV series "Prisoner: Cell Block H" where she played the role of Lizzie Birdsworth.

Is a blepharisma a fresh water dweller or a salt water dweller?

Blepharisma is generally a freshwater dweller. They are ciliated protists commonly found in ponds, lakes, and streams. While some species of Blepharisma can tolerate low salinity levels, they are more abundant and diverse in freshwater habitats.

Where are the four places protists are found?

Protists can be found in various aquatic environments, such as oceans, lakes, and rivers. They also inhabit moist terrestrial habitats like soil, leaf litter, and tree bark. Additionally, protists can be found in symbiotic relationships within the bodies of other organisms, like in the intestines of animals. Finally, some protists can thrive in extreme environments like hot springs and deep-sea hydrothermal vents.

What is the amoeba's lifespan?

According to the researches made by the scientists about the life span of amoeba,they tell they have about a life span of one or two days only...

True or false dinoflagellates are one-celled algae with two flagella?

True. Dinoflagellates are single-celled organisms belonging to the algae group, and they typically have two flagella that they use for movement. These flagella help dinoflagellates navigate through water and capture their food.

What are clusters of algae called?

Clusters of algae are called algal blooms. These blooms can occur when conditions are favorable for algae growth, such as high nutrient levels and warm temperatures. While some algal blooms are harmless, others can produce toxins that can be harmful to aquatic life and humans.

How does the amoeba digest its food?

Ameoba extends pseudopodia around the food particle until they join, enclosing the particle in a membrane-bound vesicle. A lysosome merges with the new food vacuole, dumping its enzymes in to digest the food. The products of digestion are then absorbed through the membrane.

Explain the differences in the population growth patterns of the two Paramecium species What does this tell you about how Paramecium aurelia uses available resources?

WikiAnswers will not do your homework for you. Nor will it write your discussion paper, critiques, summaries or essays. That is considered cheating. If you have a specific question in the subject we are more than willing to help.

Is an amoeba all the same colour?

Information on these organisms, often called slipper animalcules, their classification, with links to videos, images and many other sites on protists. * www.101science.com/paramecium.htm

Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together?

I hypothesize that when grown alone, the two species of Paramecium will each thrive and increase in population. When grown together, competition for resources may lead to slower growth compared to when they are alone, as they may have to share resources and space.
