What is the purpose of the G1 and G2 phases?
A. To grow a second cytoplasm before division.
B. They are growth phases to make the cell large enough to divide.
C. To make a copy of the cell's DNA.
D. They are growth phase to make the cell large enough to fight off infection.
Answer:
B.) They are growth phases to make the cell large enough to divide.
Explanation:
In G1, the cell grows in volume and number of organelles. After the DNA has replicated in the S phase, the cell continues to grow in G2. As such, the primary purpose of G1 and G2 is to prepare the cell for replication (division).
They are growth phases to make the cell large enough to divide. Therefore option B is correct.
The G1 (Gap 1) and G2 (Gap 2) phases are critical stages in the cell cycle. During G1, the cell grows and performs its normal functions, while in G2, it prepares for cell division.
The main purpose of these phases is to increase the cell's size and accumulate the necessary organelles and materials for successful cell division.
In G1, the cell ensures it has sufficient resources and energy before proceeding to the next phase, S (Synthesis), where it replicates its DNA.
After G2, the cell enters the final phase, M (Mitosis), where it divides into two daughter cells, each with a complete set of DNA and organelles.
Therefore option B They are growth phases to make the cell large enough to divide is correct.

Glucagon and insulin have antagonistic effects. glucagon signaling results in an increase in blood glucose concentration. What do you expect is the result of insulin signaling?
Since Glucagon and insulin have antagonistic effects, if glucagon signals increase in blood glucose concentration, insulin would result in a decrease in blood glucose concentration.
Glucagon and insulin are both important hormones that play essential roles in regulating your blood glucose (sugar).
Both hormones come from your pancreas — alpha cells in your pancreas make and release glucagon, and beta cells in your pancreas make and release insulin.
The two hormones counterbalance each other to stabilize blood glucose. When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon.

All vertebrate embryos have _____ at some point during embryonic development, indicating a common evolutionary ancestor
All chordates chare four structures. One of the is the tail. All vertebrate embryos have _a tail__ at some point during embryonic development, indicating a common evolutionary ancestor.
What is the relationship between chordates?The evolutionary relationship between species is reflected in the similarities or differences in the patterns of embryonic development.
All chordates belong to the Chordata phylum, and share four main characteristics,
Notochord, which is a precursor of the dorsal spine.Nerv cord, dorsally located and parallel to the notochord.Pharyngeal cleftsTail
All chordates express these structures at some point in their lives, especially in the early stages of embryogenesis. Many of them can be lost with animal development and become vestigial structures.
The tail is a vestigial structure in many vertebrates.
Vestigial structures are those body parts, genetically determined, that have been retained during the evolution of the taxonomic group but have lost or reduced their original function.
Such vestigial structures were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts
All vertebrates develop a tail at some point in their embryonic life, even humans. However, this structure lost its original function in several species, so after a period of embryogenesis, this tail disappears, and its forming vertebras get fussed with each other composing the coccyx.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, for instance, the coccyx has lost this function but is still an area of muscle insertion.
The correct option is Tail.
All vertebrate embryos have _a tail_ at some point during embryonic development, indicating a common evolutionary ancestor.

The hormone _____ stimulates the storage of triglycerides during times of energy excess.
The hormone insulin stimulates the storage of triglycerides during times of energy excess.
Insulin is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the INS gene. It is considered to be the main anabolic hormone of the body.
It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both.
Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in the blood. Circulating insulin also affects the synthesis of proteins in a wide variety of tissues. It is therefore an anabolic hormone, promoting the conversion of small molecules in the blood into large molecules inside the cells. Low insulin levels in the blood have the opposite effect by promoting widespread catabolism, especially of reserve body fat.

Which ion species is a cell membrane (such as a neuron) most permeable to at rest (i. e. , resting membrane potential)?
The cell membrane is most permeable to potassium ions at the resting membrane potential.
What is resting membrane potential?The difference in the membrane potential between the inside of a cell and the outside of a cell is called resting membrane potential. This is usually 30 to 90 mV with the inside of the cell being more negative compared to the outside of the cell.
Because of the potential difference across the cell membrane, it is said to be polarized. In a condition where the membrane potential becomes more positive than the resting membrane potential, the membrane becomes depolarized. In a condition where membrane potential becomes more negative compared to the resting membrane potential, it becomes hyperpolarized.
All electrical signals used by the neurons are either due to depolarization or hyperpolarization from the resting membrane potential.
This resting membrane potential is determined by the movement of potassium ions across the membrane.

A main outcome of ivan pavlov’s research is that a neutral stimulus can become a conditioned stimulus?
A main outcome of Pavlov’s research is that a neutral stimulus can become a conditioned stimulus only in the presence of an unconditioned stimulus that triggers an unlearned response.
What is Pavlov’s conditioning?
The classic conditioning -Pavlov conditioning- is an associative learning way. It is a behavior in which stimuli and responses are associated.
In Pavlov's conditioning, an unconditioned stimulus that usually induces a given response is associated with another conditioned stimulus -neutral- that does not provoke any response by itself.
Let us review a few concepts,
Unconditioned stimuli: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, food is an unconditioned stimulus.Conditioned stimuli: neutral, innocuous, or biologically not significant stimuli. Unconditioned Responses: Unlearned response that is triggered by reflex because of an unconditioned stimulus. An example is salivating.Conditioned Responses: These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli.Initially, an unconditioned stimulus does not provoke any response, but after enough exposure to conditioned and unconditioned stimuli together, the simple presence of unconditioned stimuli induces conditioned responses. In this aspect, the subject has learned to predict or anticipate the unconditioned stimulus.
The classic example is the one in which a dog increases its salivation secretion as an unconditioned response when it sees food -the unconditioned stimulus-.
If the unconditionated stimulus is associated with the sound of a ring bell or a light -conditioned stimulus-, after a certain time, the dog will secrete saliva when hearing the ring bell soung or seeing the light.
If the conditioned stimulus is associated with a bad experience, there is an aversion response or conditioned fear.
The main outcome of Ivan Pavlov’s research is that a neutral stimulus can become a conditioned stimulus? Yes, but only in the presence of another unconditioned stimulus (food) that triggers an unlearned response (salivation).

Moving your finger across a textured surface can produce vibrations that are interpreted as texture. These vibrations are defined as?
Moving your finger across a textured surface can produce vibrations that are interpreted as texture. These vibrations are defined as temporal cues.
Temporal envelope (ENV) or temporal cues are changes in the amplitude and frequency of sound perceived by humans over time. These temporal changes are responsible for several aspects of auditory perception, including loudness, pitch and timbre perception and spatial hearing.
Complex sounds such as speech or music are decomposed by the peripheral auditory system of humans into narrow frequency bands. The resulting narrow-band signals convey information at different time scales ranging from less than one millisecond to hundreds of milliseconds. A dichotomy between slow "temporal envelope" cues and faster "temporal fine structure" cues has been proposed to study several aspects of auditory perception (e.g., loudness, pitch and timbre perception, auditory scene analysis, sound localization) at two distinct time scales in each frequency band.
Over the last decades, a wealth of psychophysical, electrophysiological and computational studies based on this envelope/fine-structure dichotomy have examined the role of these temporal cues in sound identification and communication, how these temporal cues are processed by the peripheral and central auditory system, and the effects of aging and cochlear damage on temporal auditory processing.
Although the envelope/fine-structure dichotomy has been debated and questions remain as to how temporal fine structure cues are actually encoded in the auditory system, these studies have led to a range of applications in various fields including speech and audio processing, clinical audiology and rehabilitation of sensorineural hearing loss via hearing aids or cochlear implants.
