I know about fossils that Fossils provide a record of animals that are, or are no longer living which is the correct answer from the dropdown menu.
The history of life as recorded by fossils, which are the remains or imprints of species from past geological eras preserved in sedimentary rock, is known as the fossil record. Continents that were once together must have been together in the geological past, according to fossils of the same genus or species. The dead and organic remains of extinct species that were buried deep in the earth millions of years ago are known as fossils. It is defined in a more straightforward manner as the remains or evidence of plants and animals that once lived in the past.
When an organism or fossil demonstrates a process of steady change over time, it is said to have undergone an evolution. Extinction, on the other hand, is the event in which species vanish from the ecosystem as a result of any method, such as habitat destruction.

how are speciation and niches interconnected concepts?
Specification and niches are related ideas:
The process by which populations divide into distinct species is known as speciation. Cladogenesis describes the division of lineages as opposed to anagenesis, or phyletic evolution within lineages. Biologist Orator F. Cook used it for the first time in 1906.
A species' niche is its role within the ecosystem. In other terms, an organism's "niche" is how it "earns a living." A niche will include an organism's role in the movement of energy across the ecosystem.
Closely related species (such as sister taxa) frequently occupy incredibly diverse ecological niches and may have noticeably different geographic ranges despite sharing a shared evolutionary history.
The concept of "budding speciation" is one method that could help to explain how disparities in niche and dispersion features might swiftly evolve. "Budding speciation" is the process through which new species appear as initially small, colonizing colonies that reach reproductive isolation. This theory of species origin predicts that distributions of sister species should be noticeably lopsided at the time of speciation.

Use your understanding of free hydrogen and hydroxide ions in solution to explain why distilled water (pure H2O) would have a “neutral” pH (or a pH of 7.0)
Answer:
With all of this in mind, then, it would make sense if distilled water had a neutral pH of 7. The distillation process removes nearly all of its ionic, mineral and organic impurities, making it one of the purest forms of water available.
You are a carbon atom. You are having a wonderful (or awful) life, bonded to

A metabolic manner referred to as cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.
Four steps of Cellular Respiration
Glycolysis. During glycolysis, the six-carbon sugar glucose is going thru some of chemical changes. In the end, it's miles converted into molecules of pyruvate, an natural molecule with 3 carbons.Oxidation of pyruvate. The mitochondrial matrix, the inner most compartment of the mitochondria, gets every pyruvate produced for the duration of glycolysis.Cycle of citric acid. A four-carbon molecule and the created acetyl CoA engage and go through a chain of events, in the end renewing the preliminary four-carbon molecule.Phosphorylation through oxidation A gradient is created as protons are pumped out of the matrix as electrons flow down the chain, liberating power as they do so. Through the introduction of ATP through the enzyme ATP synthase, protons float returned into the matrix.Chemical Energy: C6H12O6 6O2 → 6CO2 6H2O (in ATP)According to the equation, oxygen (O2) and glucose (C6H12O6) react to provide carbon dioxide (CO2) and water (H2O), which releases power.

The production of APP in a neuron. APP is represented by the triangles.
Using Figure 1, label the following: neuron, nucleus, rough ER, Golgi, transport vesicles, APP, and exocytosis.
1) Labelled image in the attached files. 2) mRNA synthesis occurs in the nucleus. Protein synthesis begins in the cytoplasm and ends in the RER, where folding and the first glycosylation stage occur. In the Golgi complex, glycosylation is over, proteins are packaged into vesicles and sent to the membrane, from where they are released by exocytosis.
What is protein syntesis?Protein synthesis is the process through which new proteinic molecules are porduced. It involves transcription, translation, and maturation.
Transcription ⇒ mRNA synthesis
The first step before protein synthesis begins is to synthesize messenger RNA, mRNA. This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.Translation ⇒ Cytoplasm stage
Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
Once in the cytoplasm, mRNA meets a ribosome, which can be found in the rough endoplasmic reticulum or floating in the cytosol.
While the ribosome reads mRNA strain, tRNA adds the correct amino acids to build the polypeptide.
Maturation process
⇒ Endoplasmic Reticulum Stage
Some proteins are destined for exportation. Their synthesis starts in the cytoplasm but finishes in the Rough endoplasmic reticulum.
When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen. When the new polypeptide synthesis is complete, it is released into the reticulum lumen.
The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.
⇒ Golgi complex stage
Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.
In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids.
⇒ Destiny stage
Glycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
Exportation proteins move forwared to the membrane within vesicles. Through exocytosis events, these molecules are released.
