in cell A, what is the structure labeled X?

Answer:

excess nitrates cause algae blooms

Explanation:

Answer:

Prokaryotes lack a true nucleus with well defined nuclear membrane and other membrane-bound organelles. Mitochondria are the double membrane bound organelle and hence is absent in prokaryotes. Mesosome is an extension of the cell membrane presence in the cytoplasm as infolding and serves to increases surface area and as a site for cellular respiration in prokaryotes. Histones are positively charged proteins that serve in the packaging of negatively charged eukaryotic DNA but are absent in prokaryotes.

So, the correct answer is option A.(DNA is complexed with histones).

The statement which is not true for prokaryotic cell is that they are all parasitic. Thus, the correct option is C.

Prokaryotes are the organisms whose cells lack a nucleus and other membrane-bound organelles. Prokaryotic organisms are divided into two distinct groups which are the bacteria and the archaea, which scientists believe to have the unique evolutionary lineages. Most of the prokaryotes are small in size, single-celled organisms which have a relatively simple structure.

Examples of prokaryotic organisms are blue-green algae, bacteria and mycoplasma. Among the prokaryotes, bacteria are the most common and multiply very fast.

Therefore, the correct option is C.

(d) They are both archaea and bacteria

Answer:

electron and nuetrons

The molecules NADH and FADH₂ will carry the electrons to the electron transport chain.

These electron carrier molecules (NADH and FADH₂) are produced during the breakdown of glucose and other energy-rich molecules in the preceding steps of cellular respiration. They carry the high-energy electrons derived from these molecules to the electron transport chain, which is embedded in the inner mitochondrial membrane in eukaryotic cells.

The electrons passed through the electron transport chain ultimately combine with molecular oxygen to form water, which is the final electron acceptor in the chain.

For prokaryotic cells, the cell wall is a tough, fibrous layer that protects the cell and gives it shape and rigidity.

Prokaryotic cells are found in the domain(s) Bacteria and Archaea.

True: Prokaryotic cells have nucleoids and eukaryotic cells have nuclei.

A prokaryotic cell is distinct from a eukaryotic cell because a prokaryotic cell lacks _a nucleus_.

There is only  _1_ eukaryotic domain, it is Eukarya.

Explanation:

Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

1.An example of Batesian mimicry is when the yummy viceroy butterfly mimics the orange and black coloration of the distasteful monarch butterfly. ... Wasmannian mimicry occurs when the mimic resembles it's host (the model) in order to live within the same nest or structure. For example, several beetles closely resemble ants
