Is a truffle multicellular or unicellular?

User Avatar

Asked by Wiki User

Truffles are multicellular organisms. They are fungi belonging to the genus *Tuber* and are composed of multiple cells like other fungi. Truffles form a network of hyphae (thread-like structures) underground, and they reproduce by producing spores. These spores develop into new truffles when conditions are favorable. While truffles themselves are not visible multicellular organisms, they are comprised

How are reflexes a defense mechanism for the body?

User Avatar

Asked by Wiki User

Reflexes are automatic responses to stimuli that help protect the body from harm by allowing a quick reaction without the need for conscious thought. They help prevent potential injury by providing rapid, protective responses to potential dangers or threats. Reflexes are essential for survival as they assist in avoiding or minimizing harm to the body.

What did walther Flemming do?

User Avatar

Asked by Wiki User

Walther Flemming was a German anatomist who is known for his discovery of chromosomal structures in cells. He first observed and described the process of cell division, which he called mitosis, and identified the presence of thread-like structures that we now know as chromosomes. Flemming's work laid the foundation for our understanding of how genetic material is passed on from one generation to the next.

What part of the brain help to learn mathematic?

User Avatar

Asked by Wiki User

The prefrontal cortex, parietal lobe, and hippocampus are key brain regions involved in mathematical learning. These areas are responsible for tasks such as problem-solving, working memory, spatial reasoning, and encoding mathematical facts and procedures. Practice and repetition help strengthen the neural connections in these regions, improving mathematical abilities.

Asked by Wiki User

Rhinos are typically solitary animals, except for mothers caring for their calves. They are known to be territorial and will mark their territory with urine and feces. When confronted, they may charge at threats to defend themselves.

How do you test the viability of microbial cultures?

User Avatar

Asked by Wiki User

Microbial cultures can be tested for viability by using techniques such as plate counting, flow cytometry, and microscopy. These methods help determine the number of viable cells in a culture by measuring factors such as colony-forming units, membrane integrity, and metabolic activity. It's important to choose the appropriate method based on the specific characteristics of the microbial culture being tested.

Asked by Wiki User

Man, as a biological being, is a member of the species Homo sapiens. We are characterized by our upright posture, highly developed brain, and complex social structures. Biologically, humans have evolved specific traits that have allowed us to adapt and thrive in various environments.

What kingdoms are in archaea?

User Avatar

Asked by Wiki User

The most archaea are not divided into kingdoms, but into phyla which are:

  • Crenarchaeota (marine)
  • Euryarchaeota (halophile, methanophile, thermophile)
  • Korarchaeota (thermophile)
  • Nanoarchaeota (thermophile)
  • Thaumarchaeota (mesophile)

How do protists differ from major groups?

User Avatar

Asked by Wiki User

Protists are a diverse group of eukaryotic organisms that do not fit into the plant, animal, or fungi kingdoms. They are unicellular or simple multicellular organisms that can be autotrophic or heterotrophic. Major groups such as plants, animals, and fungi are more complex multicellular organisms with distinct structures and functions.

The scientific name for spiracal bacteria is Borrelia recurrentis.

What type of nutrition do alge have?

User Avatar

Asked by Wiki User

Algae are autotrophic organisms, meaning they can produce their own food through photosynthesis. They use sunlight, carbon dioxide, and water to make their own energy source, usually in the form of carbohydrates.

What phylum in kingdom protista does Euglena belong to?

User Avatar

Asked by Wiki User

Euglena belongs to the phylum Euglenozoa in the kingdom Protista.

Is 'Euglena' an animal or a plant?

User Avatar

Asked by Wiki User

Euglena is a single-celled organism that is neither strictly an animal nor a plant. It belongs to a group called protozoa, which are considered to be protists. Euglena can undergo photosynthesis like plants but can also feed on organic matter like animals.

Which is more primitive protista or monera?

User Avatar

Asked by Wiki User

Monera is considered more primitive than Protista. Monera consists of prokaryotic organisms, such as bacteria and archaea, which are among the oldest and simplest forms of life on Earth. Protista, on the other hand, consists of eukaryotic organisms that are more complex and evolved compared to Monera.

What is the scientific name of enzymes?

User Avatar

Asked by Wiki User

Enzymes belong to a class of proteins called "biocatalysts" and do not have a single scientific name. They are named based on the substrate they act upon and end with the suffix "-ase." For example, the enzyme that breaks down proteins is called protease.

When did archaebacteria first appear?

User Avatar

Asked by Wiki User

Prokaryotic fossils have been dated to 3.5 billion years ago, but it is not possible to determine by their shape if they were Archaea. Some lipids, consistent with eukaryotes or archaea, have been detected in shale dating to 2.7 billion years ago. The split between bacteria and archaea probably occurred earlier than that; the lipid remnants could be from either one or both. In light of genetic research since the 1960s, it is no longer held as a certainty that eukaryotes developed from archaea; they may have developed as separate, parallel lines of descent from primordial organisms. That is why the term "archaebacteria" has fallen out of use; Archaea are now classified as a separate domain of living organisms from Bacteria.

Does pseudomonas aeruginosa grow on blood agar?

User Avatar

Asked by Wiki User

Yes, Pseudomonas aeruginosa can grow on blood agar, but it may not show the typical hemolysis patterns like other bacteria. It usually appears as flat, greenish colonies on blood agar plates.

Why does brown seaweed belong to the protista kingdom?

User Avatar

Asked by Wiki User

Brown seaweed belongs to the protista kingdom because it is a type of algae known as Phaeophyta. Algae are simple, plant-like organisms that lack specialized tissues found in higher plants and are classified under the protista kingdom due to their unique characteristics and evolutionary history.

Why are archaebacteria not classified in the same kingdom as eubacteria?

User Avatar

Asked by Wiki User

Archaebacteria are not classified in the same kingdom as eubacteria because they have fundamental genetic and biochemical differences, such as unique cell membrane components and gene sequences. These distinctions suggest that archaebacteria have evolved separately from eubacteria and are more closely related to eukaryotes in terms of evolutionary history.

What does the kingdom Monera have?

User Avatar

Asked by Bnatay

The kingdom Monera includes single-celled organisms like bacteria and cyanobacteria. These organisms lack a true nucleus and other membrane-bound organelles found in eukaryotic cells. They are typically prokaryotic, meaning their genetic material is not enclosed in a nucleus.
