Proteins play key roles in olfaction. One kind of protein, called ___________, attaches itself to hydrophobic odorant molecules so that they may dissolve in watery mucous. A second class of proteins, to which odorant molecules become bound and initiate transduction, are coded by the largest family of genes in mammals and are called ___________ . Group of answer choices
Answer:
The correct answer is "Odorant-binding proteins (OBPs); Olfactory receptors (ORs)".
Explanation:
Odorant-binding proteins (OBPs) are low-molecular soluble molecules that are secreted in high amounts in the nasal mucus layer. The precise biological activity of OBPs remains unclear, however, its solubility and ability to attach to hydrophobic odorant molecules suggest that they acts as carriers. A second class of proteins called olfactory receptors (ORs), act at the genetic level by initiating transduction once odorant molecules attach to them. ORs are coded by the largest family of genes, which include more than 100 genes and pseudogenes that represent around 3% of the genome.
The wells that contain the DNA samples are placed next to the negatively charged electrode in the electrophoresis box (chamber) because _______. Group of answer choices DNA strands have both a positive and a negative charge DNA is negatively charged DNA is positively charged DNA has no electrical charge
Answer:
DNA is negatively charged
Explanation:
Electrophoresis: In biology, the term "electrophoresis" is described as one of the different laboratory technique that is being utilized to separate protein molecules, DNA, and RNA one the basis of their electrical charge and size. Therefore, a specific amount of "electric current" is being used to move different molecules that are required to be separated through a "gel". The given gel contains pores that generally works like a "sieve" and thus allows every small molecule to proceed faster as compared to the larger molecules.
DNA stands for "deoxyribonucleic acid" is determined as a long molecule that ought to contain an individual's unique "genetic code" and generally carried information associated for making proteins in an individual's body.
In the question above, the correct answer is "DNA is negatively charged".
The samples of DNA are placed next to the negatively charged electrode in the electrophoresis as DNA is negatively charged.
What is electrophoresis?It is a laboratory technique, which is used to distinguish RNA, DNA or molecules of protein on the basis of their electrical charge and size. In the process, an electric current is utilized to move molecules to be separated via a gel. The gel comprises pores that functions as a sieve, which permits smaller molecules to move faster in comparison to larger molecules.
DNA is a negatively charged molecule, thus, when it is used in the process of electrophoresis, the migration of DNA will take place towards the positively charged electrode. Through the gel, the DNA with shorter strands will move more briskly in comparison to the longer strands leading to the formation of fragments being aligned in order of size.
Thus, the samples of DNA are placed next to the negatively charged electrode as they are negatively charged.

What could happen if the cell cycle for the cells in your pinky finger stopped functioning properly? (Check all that apply.)
Answer:
Hello, you did not enter the answer options, but I can help you by explaining what would happen in this case.
if the cell cycle of the cells in your little finger stops working properly, two things could happen. First, if these cells were unable to start and complete the cell cycle, your finger would be unable to heal cuts and bruises that could happen to it, on the other hand, if these cells were unable to end the cell cycle, your finger would develop cancer .
Explanation:
The cell cycle allows the cells of your circus, in this case, of your little finger, to multiply and create exactly the same cells. This process is very important to not only make your finger grow, but also to be able to heal cuts and bruises, regenerating the tissues and skin of your finger.
Unfortunately, over time, or as a result of some factors, cells may have defects in the cell cycle. In short, if the cells are unable to start and complete the cell cycle, your finger will be unable to create new cells and regenerate tissues and skins if your finger is cut or injured. In addition, the cells may not be able to finish the cell cycle and multiply in an exaggerated and unregulated way, generating a cancer in the finger.

B. Direct contact
C. Hormones
D. Enzymes
Answer:
C: Hormones
Explanation:
hormones do not "signal" other cells. I hope this helps :)
The correct answer is option C. Hormones.
What is the simple definition of hormones?Hormones are chemicals that act like messenger substances in the body. After being made in one part of the body, they move to other parts of the body, where they help control how cells and organs work. For example, insulin is a hormone made by the beta cells of the pancreas.
In endocrine signaling, signaling molecules (hormones) are secreted by specialized endocrine cells and transported through the circulatory system to affect target cells in remote parts of the body.
Hormones are so many essential parts of your body's system that they regulate much of what your body does. Hormones regulate growth, libido, sexual development, reproduction, sexual function, metabolism, and thirst, among other things. They simply tell the body what to do to keep it running smoothly.

Approximately ___ of the gametes produced by an individual heterozygous for a deletion will be non viable.
Answer:
1/2 (50%)
Explanation:
During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring
Areas on the moon called maria Select one: a. are seas of water. b. consist of basaltic lava. c. formed a million years ago. Clear my choice
Areas on the moon called maria consists of basaltic lava. Option B is correct.
The areas on the moon called maria are not actually seas of water, as option a suggests. Instead, they are large, dark, flat areas on the moon's surface. These areas were formed by ancient volcanic activity.
Maria are made up of basaltic lava, which is a type of lava that is low in viscosity and can flow easily. When volcanic eruptions occurred on the moon in the past, this lava flowed out onto the surface and covered large areas, creating the maria.
These volcanic eruptions and the formation of the maria took place billions of years ago, not just a million years ago as option c suggests. They are remnants of the moon's early history when volcanic activity was more prevalent.

Which of the following is false? Unselected Under normal conditions, blood PO2 affects breathing only indirectly. Unselected Changes in arterial pH resulting from CO2 retention or metabolic factors act through the peripheral chemoreceptors. Unselected When arterial PO2 falls below 60 mm Hg, it becomes the major stimulus for respiration. Unselected Oxygen levels are the primary stimulant of respiration.
Answer:
The sentence that says: Blood PO2 affects respiration only indirectly, IT IS FALSE, since the partial pressure of oxygen gas together with carbon dioxide are factors that DIRECTLY affect respiration.
The sentence that says: Unselected changes in arterial pH as a result of CO2 retention or metabolic factors act through peripheral chemoreceptors. It is FALSE, since the central chemoreceptors together with the peripheral ones can detect the metabolic acidosis generated by the CO2 retention, this is how the CNS receptors capture the CO2 that crosses the blood-brain barrier and stimulates hyperventilation to compensate for this phenomenon and increase the plasma concentrations of partial oxygen pressures.
The sentence that says: in selecting When arterial PO2 falls below 60 mm Hg, it becomes the main stimulus for breathing, IT IS FALSE, since it not only encourages ventilation to promote oxygenation but also activates the renin-angiotensin-aldosterone in order to recover blood volume and thus achieve adequate blood pressure.
In addition, hypovolemia triggers tachycardia and weakening symptoms, which is why the drop in blood pressure is not the main stimulus for breathing.
Explanation:
Breathing is promoted by muscle contraction, medium and high temperatures (that is, in hot or hot climates), partial concentrations of oxygen and carbon dioxide both in the atmosphere and in our blood, and in situations of systemic imbalances such as metabolic acidosis or alkalosis.

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.
