1.6 Protists that look like fungi.
(6)
Answer:
1.1 Amoeba
1.2 Paramecium
1.3 Citations
1.4 Single algae cells
A protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
What are Protists?A protist is a type of eukaryotic organism which is not an animal, plant, or fungus sharing a common ancestor. These are to the exclusion of other eukaryotes which means protists do not form a natural group or clade.
Protists are a group of diverse eukaryotic mainly unicellular microscopic organisms which share certain morphological and physiological characteristics with animals or plants or both.
Several protists showing different functions like an amoeba pushes out its cell membranes to form pseudopods. Euglena belongs to the class of protozoans known as flagellates. Spirogyra has a slender bright green color with a spiral shaped pigment that holds chlorophyll. Chlamydomonas is found in ponds, ditches and moist soil. Diatoms have a silky jewel-like covering. A mold is a protist which is a fungus.
Thus, a protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.

What process is the driving force behind evolution?
Answer:
Mutations and natural selection are the main ones
Explanation:
The process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.
What is the significance of natural selection over time?Natural selection is important for the survival of organisms as it is a process by which populations of organisms change over time in response to the outer environment. It is also an important evolutionary mechanism because natural selection always chooses the fittest and natural selection also drives the development of new species and helps ensure the survival of existing species.
Hence, the process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.

Look again at the enzyme diagram and it’s target molecule. How might a mutation affect the interaction between the enzyme and its target and the function of the enzyme in the organism?
By viewing the enzyme diagram and its target molecule, we can infer that a mutation might affect the interaction between the enzyme and target because it may change the shape of the enzyme and consequently inhibit its function.
What is a genetic mutation?A genetic mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, which affects the production of a protein and may have a wide range of effects on the function of a cell.
Therefore, with this data, we can see that a genetic mutation may modify the protein and thus affect the reaction.

What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️
