Why has the kingdom protista been abandoned? see concept 28.1 (page 592) view available hint(s) why has the kingdom protista been abandoned? see concept 28.1 (page 592) some protists are multicellular. the kingdom protista is not monophyletic. some protists are more closely related to plants, animals, or fungi than they are to other protists. some protists are as small as prokaryotes. the second and third answers are correct. submit?
The Kingdom Protista was abandoned because it was found to be a paraphyletic group, meaning not all descendants of its last common ancestor were included in the kingdom. This discovery was made possible due to advancements in molecular genetics revealing that some protists are more related to animals, plants, or fungi than they are to other protists.
Explanation:The kingdom Protista, first suggested by Ernst Haeckel, used to include all eukaryotic organisms that did not fit the criteria for kingdoms Animalia, Fungi or Plantae. However, with the advent of DNA sequencing and molecular genetics, it has been discovered that some protists are more related to animals, plants, or fungi than to other protists.
As a result, the kingdom Protista has been disassembled as it does not represent a monophyletic group (a group of species that includes an ancestral species and all its descendants). This means that some descendants of its last common ancestor are excluded from the kingdom, making it a paraphyletic group and contradicting the principles of modern taxonomy.
Therefore, protist lineages originally classified into the kingdom Protista have been reassigned into new kingdoms or other existing kingdoms in light of new genetic relationships revealed through molecular genetics. Protists, however, continue to be a tremendously diverse group of eukaryotes dwelling in a variety of environments and exhibiting various forms of morphologies, physiologies, and ecologies.

The attraction of water molecules to other kinds of molecules is called
Adhesion is the attraction of water molecules to other kinds of polar molecules, which occurs due to hydrogen bonding formed because of water's polarity, creating interactions with hydrophilic substances.
The attraction of water molecules to other kinds of polar molecules is known as adhesion. This phenomenon occurs because water molecules are polar, which means they have a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. As a result of water's polarity, each water molecule can form hydrogen bonds with other polar molecules or ions, leading to this adhesive attraction. This forms the basis for many of water's unique properties, such as its ability to dissolve various substances, creating hydrophilic (water-loving) interactions. In contrast, molecules that do not mix well with water, such as oils, are described as hydrophobic (water-fearing).
Expression of a cloned eukaryotic gene in a bacterial cell involves many challenges. the use of mrna and reverse transcriptase is part of a strategy to solve the problem of _____.
Out of the flowing given choices;
A) post-transcriptional processing.
B) electroporation.
C) post-translational processing.
D) nucleic acid hybridization.
E) restriction fragment ligation.
The answer is A. Bacteria do not have a complex post-transcriptional processing tool such as the one in eukaryotes cells. Therefore, they are not able to process pre-mRNA with introns, example splicing. Therefore, a fully processed mRNA is cloned into the bacterial cell so it is reverse-transcribed into cDNA by reverse transcriptase.

Which body of water is often protected naturally from storms by barrier islands and also contains a mixture of fresh water and salt water?
What type of cells is yogurt and cheese made out of?
Final answer:
Yogurt and cheese are made from bacterial cells, particularly from Lactobacillus, Bifidobacterium, and Streptococcus species. These prokaryotic cells ferment milk sugars into lactic acid, causing milk proteins to denature and form yogurt and cheese.
Explanation:
The type of cells used in the production of yogurt and cheese are bacterial cells. These products are typically made using prokaryotic cells, specifically from bacteria such as Lactobacillus, Bifidobacterium, and Streptococcus species. These bacteria ingest the natural sugars found in milk and release lactic acid as a waste product. The accumulation of lactic acid causes the proteins in the milk to denature and form into either a viscous, semi-solid mass for yogurt or a solid mass for cheese.
Yogurt specifically is produced by fermenting milk with strains of bacteria such as Lactobacillus bulgaricus and Streptococcus thermophiles. These bacteria are rod-shaped (bacilli) and often arranged in pairs or short chains. Cheese, on the other hand, has been traditionally made by fermenting milk with a variety of bacteria and sometimes molds, depending on the type of cheese being produced. This process not only enhances the flavor but also preserves the milk, as fermentation products like yogurt and cheese tend to be more stable and less prone to spoilage.

Where are the proteins of the electron-transport chain located in chloroplasts?
The proteins of the electron-transport chain in chloroplasts are located in the thylakoid membrane, where they play a key role in the light-dependent reactions of photosynthesis.
The proteins of the electron-transport chain in chloroplasts are located in the thylakoid membrane. Chloroplasts capture the energy of light, where the water is split and oxygen is released during the light-dependent reactions of photosynthesis. The electron-transport chain is part of this process, where electrons are transferred through a series of redox reactions, extracting energy to form NADPH and to pump protons across the membrane, generating a proton motive force that drives ATP synthesis. The thylakoid membrane provides the necessary environment for these reactions, housing the electron-transport chain and other crucial components such as Photosystem I (PSI) and Photosystem II (PSII).
In eukaryotes, the electron transport chain in chloroplasts operates similarly to its counterpart in the mitochondria, though they are located in different structures within the cell. Both are essential for ATP production, though they differ in their initial source of electrons; in chloroplasts, the initial electrons come from the splitting of water molecules.

What is the difference between an epistatic gene and a hypostatic gene? an epistatic gene is dominant; a hypostatic gene is recessive. an epistatic gene produces only two phenotypes; a hypostatic gene produces four phenotypes. an epistatic gene masks the effects of another gene; a hypostatic gene is masked by the epistatic gene. an epistatic gene enhances the effects of another gene; a hypostatic gene reduces the effects of another gene. an epistatic gene masks the effects of another gene when the epistatic gene has one or more dominant alleles; a hypostatic gene masks the effects of another gene when the hypostatic gene has two recessive alleles?
Epistasis is an interaction between genes where one gene masks or interferes with the expression of another gene. The epistatic gene masks the effects of the hypostatic gene, and this can happen through dominant alleles or two recessive alleles. Phenotypes can be affected by the interaction between these genes, leading to a different number of phenotypes than usual.
Explanation:Epistasis is an interaction between genes where one gene masks or interferes with the expression of another gene. The gene that does the masking is called the epistatic gene, while the gene being masked is called the hypostatic gene. Epistatic genes can have dominant alleles that mask the effects of the hypostatic gene, while hypostatic genes can be masked when they have two recessive alleles. The interaction between epistatic and hypostatic genes can affect the expression of phenotypes in different ways, such as producing fewer or more than the usual number of phenotypes.
