the connection formed between the actin and myosin is known as what?
Answers
The connection formed between actin and myosin is known as a cross-bridge.
It is a temporary chemical bond that is formed between the myosin head and the actin filament during muscle contraction. The cross-bridge is formed when the myosin head binds to the actin filament, creating a temporary link between them.
The formation of cross-bridges is an important step in the sliding filament theory of muscle contraction. The interaction between actin and myosin generates force and allows for muscle movement. Without the formation of cross-bridges, muscle contraction would not be possible.

broken ribs usually occur along the side of the ________.
A.) chest
B.) lungs
C.) heart
Answers
Broken ribs usually occur along the side of the chest. The correct answer is A) chest.
Broken ribs, also known as rib fractures, commonly occur along the side of the chest. The ribs are long, curved bones that form the rib cage, providing protection to vital organs such as the lungs and heart. The rib cage consists of 12 pairs of ribs that extend from the spine to the front of the chest.
Due to their location and structure, ribs are vulnerable to injury, especially from direct trauma or excessive force to the chest area. Common causes of broken ribs include falls, motor vehicle accidents, sports injuries, and physical altercations. When a rib fractures, it can cause significant pain, discomfort, and difficulty breathing.
The exact location of the fracture may vary, but it typically occurs along the lateral (side) portion of the chest, where the ribs are more exposed and susceptible to external forces.

The percentage of cells in each phase or stage can be used as a measure of how long each phase lasts. The cell cycle in onion cells takes 1,440 minutes (24 hours), so if you take the percentage of cells in each phase and convert it to a decimal figure by dividing by 100 and then multiply the amount of time the cell cycle takes, you can calculate the approximate time each stage or phase of the cell cycle lasts. Formula: Duration of phase (in minutes) = percentage/100 X 1,440 minutes
Answers
The formula for calculating the duration of each phase or stage of the cell cycle in onion cells is as follows: Duration of phase (in minutes) = (percentage/100) × 1,440 minutes.
The cell cycle in onion cells takes 1,440 minutes or 24 hours. By determining the percentage of cells in each phase and converting it to a decimal by dividing by 100, we can calculate the proportion of time each phase or stage lasts within the total cell cycle. Multiplying this proportion by the total duration of the cell cycle (1,440 minutes) gives us an estimate of the time each phase or stage lasts. This formula allows us to approximate the duration of different phases of the cell cycle based on the percentage of cells observed in each phase.

The ______ ________ ________ is when
excited electrons lose

necessary to "keep life living."
Answers
The electron transport chain is when excited electrons lose their energy in a series of reactions that capture that energy necessary to "keep life living."
This process occurs in the mitochondria of cells and is a crucial part of cellular respiration, as it generates ATP (adenosine triphosphate), which is the energy currency of the cell. The electron transport chain is the final step in the process of converting the energy stored in food molecules into usable energy for the cell.
The electron transport chain is a series of protein complexes that transfer electrons through a membrane within the mitochondria of cells. The net result of this process is the production of energy in the form of ATP, which can then be used to power various cellular activities. The electron transport chain begins with the oxidation of NADH and FADH2 molecules, which then donate electrons to a series of electron carriers.

.A geneticist conducts an experiment with peas, one sample of offspring consisted of 483 green peas and 159 yellow peas. Based on these results, estimate the probability of getting an offspring pea that is green.
Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.
prob = ____________ %
Is the result reasonably close to the value of 3/4 that was expected?
yes or no
Answers
The probability of getting an offspring pea that is green by the geneticist is 75 %.
The result is reasonably close to the expected value of 3/4, which is equivalent to 75%.
To estimate the probability of getting a green pea offspring, we can use the ratio of green peas to the total number of peas in the sample.
The total number of peas in the sample is 483 + 159 = 642.
The probability of getting a green pea offspring is given by:
Probability of green pea = Number of green peas / Total number of peas
Probability of green pea = 483 / 642
To convert this to a percentage, we multiply by 100:
Probability of green pea = (483 / 642) * 100
Calculating this value gives us:
Probability of green pea = 75.2%
The result is reasonably close to the expected value of 3/4, which is equivalent to 75%.

when a hormone binds a nuclear receptor and increases transcription, which of the following results?
a. DNA produces mRNA.
b. G proteins are activated.
c. the hormone-receptor complex causes ion channels to open or close.
d. the cell’s response is faster than when a hormone binds to a membrane-bound receptor.
e. the hormone is usually a large, water-soluble molecule.
Answers
A hormone binds a nuclear receptor and increases transcription, DNA produces mRNA. This is because nuclear receptors are found in the nucleus and regulate gene expression by binding to specific DNA sequences and increasing the transcription of genes.
The hormone-receptor complex enters the nucleus and binds to specific DNA sequences called hormone response elements (HREs).
This binding activates transcription factors that recruit RNA polymerase to the gene, resulting in the production of mRNA.
In summary, the binding of a hormone to a nuclear receptor results in the activation of transcription factors, which increase the transcription of specific genes by binding to HREs on DNA and producing mRNA. This process is slower than when a hormone binds to a membrane-bound receptor, but can have longer-lasting effects on the cell's behavior. The size and solubility of the hormone can vary, but many hormones that bind to nuclear receptors are large and hydrophobic.

how are neurotransmitters removed from the synaptic cleft
Answers
Neurotransmitters are eliminated through a variety of processes, but they are always either degraded by transmitter-specific enzymes, reabsorbed into nearby glial cells or nerve terminals, or a combination of these processes.
Diffusion: The neurotransmitter leaves the synaptic cleft, where it is no longer able to act on a receptor, and drifts elsewhere. Enzymatic degradation (deactivation): This process involves altering the structure of the neurotransmitter so that the receptor cannot recognize it.
Neurotransmitter activity can be stopped in two different ways: by reuptake pumps or by enzymatic breakdown. A neurotransmitter diffuses across the synapse after being released from the presynaptic neuron and binds to receptors on the post-synaptic cell.

huntington's disease occurs when a cag repeat expansion in the coding region of the htt gene becomes too long. the cag repeat is also in frame. (... | cag | cag | cag | ...) which amino acid is coded for in this repeat?
Answers
The amino acid which codes for the CAG repeat in the coding region of the HTT gene is glutamine.
Huntington's disease is brought on by an increase of the CAG repeats in the HTT gene's coding region. The amino acid glutamine is encoded by the CAG repeat. This is believed to be related to the overproduction of glutamines, or polyglutamine, which alters the huntingtin protein's normal structure and raises the risk of hazardous aggregation formation.
A healthy person has up to 36 CAG repeats, and those who have more than this typically get Huntington's disease. The HHT gene's inherited CAG repeat length has been demonstrated to influence the age at which individuals experience motor symptoms, with greater repeat expansions causing earlier onset.
