Answer:
A. cnidarians
Explanation:
Comb jellies are most closely related to Cnidarians. Cnidarians are marine invertebrate organisms which make use of their cnidocytes filled with tentacles in catching preys.
They also have body parts such as the ectoderm and endoderm and a characteristic middle jelly layer called the mesoglea which is similar in a comb jelly.
Examples of Cnidarians include sea anemones and corals.

Population, community, ecosystem, biome is the order of the individual numbers.
A population is defined as the group of same species in a particular area that live together and depend on same kind of food with same reproductive habits.
The community is defined as the collection of all the living organisms in a particular region. All the different species residing in a particular habitat is considered as the community.
The ecosystem consists of the both living and the non living objectsorganisms in a particular region. All the living organisms as well as the soil, rock, wind etc forms the ecosystem of a region.
The biome is defined as the large geographical region where the different organisms reside and it also gives an idea about the geographical features of the region.

macronutrients
Answer:
macronutrients
Explanation:
macronutrients are important for growing plants. the main macronutrients are nitrogen, Potassium, and phosphorus.
Answer:
The second answer.
Explanation:
Answer:
Using microscopy methods such as fluorescence microscopy and polymerase chain reaction (PCR).
Explanation:
A bacterium that is viable but non-culturable refers to those bacteria that are in a very low metabolic state (dormant state) that don’t grow but is alive. Methods based on culture will not be able to detect a viable but non-culturable bacteria, because these bacteria will not grow and in few cases if the bacterium could be cultured, it only grows in very specific conditions. The most common methods used to check for the presence of bacteria that are viable but non-culturable is the fluorescence microscopy. The disadvantage of this technology is that don’t discriminate between live and dead cells, it only detects its presence. Another common technology is a polymerase chain reaction (PCR), that detects DNA, but this technique also doesn’t discriminate between living or dead cells. But usually is combined with stains to detect a damaged of the membrane, this damage refers to nonviable bacteria.
Answer:
B.8
Explanation:
In a dividing cell, each chromosome consists of two chromatids. Both the chromatids remain attached at the centromeres. If in a dividing cell there are 8 centromeres, indicates that dividing cell has 8 chromosomes. Chromosomes separate during anaphase. The cell is still dividing and not separated into two daughter cells. Therefore, if the cell has 8 centromeres during metaphase, the same number of centromeres will be present during anaphase. Thus, 8 is the correct answer.
Answer:
Explanation:
Synthetic is something that is not made from natural materials but rather made from the synthesis of other materials in a lab. This is mostly done in clothing where you have some natural materials like cotton and other materials that are synthetic. This doesn't mean it is not high quality. It is actually preferable for some sports for example to wear synthetic clothing instead of cotton.
that would not be possible without phosphorus.
Answer:
It would be impossible to store and transfer genetic information
It would be impossible to carry out majority of cellular activities due to lack of usable energy.
Explanation:
Phosphorus, as stated in the question, represents a very low amount in our body system, however, its role in living systems cannot be underestimated. Phosphorus is a vital component of major biomolecules in our system.
- It is the building block of the NUCLEOTIDES that make up nucleic acids. Nucleic acids (DNA and RNA) store genetic information and help transfer it to offsprings. However, without one of the elemental components (phosphorus) that make up its structure, it will not be produced. Hence, the storage and transfer of genetic information will be impossible.
- Phosphorus also makes up the structure of the ADENOSINE TRIPHOSPHATE (ATP) molecule. ATP provides the cell with all the energy used in carrying out cellular functions. However, the absence of phosphorus needed for the synthesis of ATP, ATP will not be produced and ultimately no energy.
Phosphorus is necessary for DNA, RNA, ATP, phospholipids, enzyme activation, energy metabolism, and pH balance in cells.
Phosphorus is an essential element in the human body and plays a crucial role in various cellular functions. One of the primary functions of phosphorus is its role in the structure and function of DNA, RNA, and ATP (adenosine triphosphate), which are all fundamental to cellular processes. Phosphorus is also involved in the formation of phospholipids, which are the main components of cell membranes.
Furthermore, phosphorus is important for the activation of enzymes, regulation of cellular energy metabolism, and maintaining pH balance within cells. The (ATP) molecule's structure is made up of phosphorus as well. All of the energy required for the cell to perform its cellular processes is provided by ATP. However, because phosphorus is required for the synthesis of ATP, ATP cannot be created, which results in the absence of energy.
