Answers
The genetic mutations in the genome appear at constant rates across a wide diversity of taxa. It led to the development of: molecular clocks.
What are molecular clocks?Molecular clocks are a technique that uses the mutation rate to measure the number of random mutations of the organism's gene at a relatively constant rate over a specific timeframe. This technique is very useful for calibrating fossil records and geological timescales. For example, an alpha-globin has a constant rate change of .56 changes per base pair per billion years. With this rate, alpha-globin could be used as a molecular clock.

Answer:
Hemoglobin.pulmonary artery.
Explanation:
1. about hemoglobin.Hemoglobin is the protein inside red blood cells. It carries oxygen.
2. about pulmonary artery.The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
3. There exist a concentration difference of carbon dioxide and oxygen inside the alveoli and capillaries due to which the diffusion of the two gases takes place. The carbon dioxide moves from the blood to the alveoli sac and the oxygen moves from the sacs to the blood.

If these examples are density independent or dependent limiting factor
Answers
In ecology, density is a measure that refers to how many individuals a population has in a specific habitat.
Considering this, we can say that water is a density-dependent limiting factor, since this is a limited resource that can vary its availability annually, but also is a species have too many individuals, all of them will not have the same capacity to reach this resource, especially when we talk about large animals or plants.
Diseases caused by bacteria would be also a density-dependent limiting factor, since only when too many microorganisms of a pathogenic species replicate in our bodies, do we begin to feel the symptoms of that illness.
Predators are also a density-dependent limiting factor since the species which they feed on can be overhunted by them, being reduced in number of individuals, or being not too much hunted and increase their individuals.
Earthquakes are a density-independent limiting factor, since they do not depend on other factors to occur, but only on the movement of our planet's plates.
Finally, limits population regardless of how many organisms are present in the area is a density-independent limiting factor, since they do not depend on how many organisms they're to limit the increase of the population. Being this option an abiotic kind of non-limiting factor.
A student grabs a handout from the teacher and gets a painful paper cut. What type of receptor is responsible for this sensation
Answers
A student grabs a handout from the teacher and gets a painful paper cut. This sensation is a result of the activation of nociceptors, which are special sensory receptors found throughout the body.
These receptors are specifically designed to detect potential tissue-damaging stimuli, such as intense heat and pressure, and send signals to the brain so the body can respond appropriately. In this case, the paper cut has damaged the skin tissue and activated the nociceptors, leading to a painful sensation.
This sensation is further amplified by the neurochemical release of substance P, which is a neuropeptide that is released from the axon terminals of nociceptors and makes the pain sensation worse. As a result, the student is able to recognize the sensation of pain coming from the paper cut and take action to address it.

It belongs to the chalcogen group in the periodic table, is a very reactive nonmetal, and is an oxidising agent that easily forms oxides with most elements as well as with other compounds. The most plentiful element on Earth and the third most prevalent element in the universe (after helium and hydrogen) is oxygen. The element forms dioxygen, an odorless and colorless diatomic gas with the formula O2 when two of its atoms come together at ordinary temperature and pressure. Currently, 20.95% of the Earth's atmosphere is made up of diatomic oxygen gas, however, over very long stretches of time, this percentage has shifted significantly.

Translation begins at an AUG codon and encodes for the amino acid
The translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum make proteins after the process of converting DNA to RNA in the cell's nucleus, as defined by molecular biology and genetics.
A messenger RNA (mRNA) molecule's genetic code is deciphered during translation, which results in a precise order of amino acids in a polypeptide chain. Similar to transcription, it takes place in the cytoplasm after DNA transcription and has three stages: initiation, elongation, and termination.
The process by which information contained in messenger RNA (mRNA) guides the addition of amino acids during protein synthesis is known as translation in the context of genomics.

Which statement best describes what happens during translation?
Answers
Answer:
B
Explanation:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
During translation, the ribosome reads the mRNA and uses the information to assemble a protein.
Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.
Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.
The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.
