When a person overdoses on drugs, ultimately, what brain structure was shut down to produce death?
A Final statement or concluding statement
'Medulla' shuts downs as a result of drug overdose.
Why shutting down of Medulla results in death?Usually, medulla damage results in death. Additionally, morphine (and other opiate medications), cocaine, and amphetamine have a very strong effect on this region. Through the impairment of cardiovascular function, these medicines have the potential to result in drug overdose. The development of apnea and a lessened respiratory response to hypoxia are both brought on by receptors, which also produce a medullary diminished response to hypercarbia.

In a plant species, if the b1 allele (blue flowers) and the b2 allele (white flowers) are incompletely dominant (b1b2 is light blue), what offspring ratio is expected in a cross between heterozygotes?
This is a case of incomplete dominance, In a cross between heterozygotes b1b2 the ratio will be 1:2:1.
When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance. This sort of gene interaction frequently produces an intermediate or distinct phenotype. Additionally called partial dominance. Pink blossoms of the four o'clock flower (Mirabilis Jalapa) and physical traits in people, such as hair color, hand sizes, and height, are instances of incomplete dominance. When the two alleles combine to create a third phenotype that differs from both of the parents, this is known as incomplete dominance. The standard illustration is when a red flower and a white flower are combined.
the cross for two individuals with genotype b1b2 is as follows:
b1b2 X b1b2 (parent)
b1b1, b1b2, b1b2, b2b2 (offspring)
thus the ratio will be 1:2:1 (blue: light blue: white)

Why does strength and contrcation increase somwhat after a few stimulation/contraction events?
The muscle generates stress during the contraction phase, which is accompanied by the cycling of the cross bridges. During the relaxation phase, the muscle lengthens back to normal.
All of the muscle fibers connected to that motor neuron will contract as an action potential moves down the motor neuron. A muscle twitch is the contraction caused by a single action potential. A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase. The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle. This period of time is necessary for calcium to diffuse out of the SR, bind to troponin, transfer tropomyosin away from the active sites, build cross bridges, and pick up any slack in the system.learn more about contraction phase here: https://brainly.com/question/26765109

If a diploid cell containing a large number of chromosomes skipped crossing over but completed the other steps of meiotic cell division to produce gametes, what would be the outcome?
The daughter cells will have paternal or maternal chromosomes.
What is crossing over?It is a major step in meiotic cell division during which non-sister chromatids exchange chromosomal segments, and as such, the genetic materials in the segments.
The process of crossing over happens at prophase I of meiosis I with the result being daughter cells whose chromosomes have been recombined as well as reconstructed.
Without crossing over, meiosis will end up producing daughter cells with either maternal or paternal chromosomes. The effect is that the number of genetic recombination in the daughter cells has been significantly reduced.

Why are temperatures more moderate around
the fall and spring equinoxes?
• The angle at which Earth's axis tilts changes.
• Neither end of Earth's axis is tilted toward the Sun.
© The north end of Earth's axis is tilted toward the Sun.
• The Earth briefly wobbles on its axis.
Answer:
The angle at which Earth's axis tilts changes.
Explanation:
As the axial tilt increases, the seasonal contrast increases and this subsequently results in winters getting colder and summers getting warmer in both hemispheres. The tilt is also responsible for various seasons that the Earth witnesses.
Temperatures are more moderate around the fall and spring equinoxes because neither end of Earth's axis is tilted toward the Sun during these times. Therefore, the correct option is B.
What are spring equinoxes?This occurs when the sun moves north across the celestial equator. During the fall and spring equinoxes, the Earth's axis is neither tilted away from nor toward the Sun, resulting in approximately equal amounts of daylight and darkness at all latitudes.
This means that the Sun's rays are hitting the Earth's surface more directly at the equator and at a more oblique angle at higher latitudes. This results in more moderate temperatures, as the temperature differences between the equator and higher latitudes are minimized.
The angle at which Earth's axis tilts changes over a long time period, which can lead to changes in climate patterns over thousands of years. Therefore, the correct option is B.

About how many total atp equivalents are generated by the complete oxidation of one molecule of acetyl coa?
Around 12 ATP equivalents are generated by the complete oxidation of one molecule of acetyl CoA.
Glycolysis begins when glucose enters, producing 2 pyruvate molecules. These pyruvates are subsequently transformed into two molecules of acetyl CoA. With each acetyl CoA that enters the citric acid cycle, three NADH (9 ATP), one FADH (2 ATP), and one GTP are produced (1 ATP). Each mole of acetyl-CoA will therefore yield 12 ATP molecules in total.
Electron transport from the citric acid cycle's energy precursors in step 3 causes oxidative phosphorylation, which phosphorylates ADP to produce ATP. In animals the majority of the energy required in biosynthesis, preserving appropriate ion balance, and mechanical work comes from oxidative phosphorylation.

How does 1 act human after being in isolation for years.
Answer:
the behaviour is disturbed
Explanation:
One of the reasons that living in isolation is difficult is because humans are social creatures. Many people that have lived in isolated environments – such as researchers stationed in Antarctica – report that loneliness can be the most difficult part of the job. Yossi Ghinsberg, an Israeli adventurer and author who survived weeks alone in the Amazon, said that loneliness was what he suffered from most and that he had created imaginary friends to keep himself company.
Loneliness can be damaging to both our mental and physical health. Socially isolated people are less able to deal with stressful situations. They’re also more likely to feel depressed and may have problems processing information. This in turn can lead to difficulties with decision-making and memory storage and recall.
People who are lonely are also more susceptible to illness. Researchers found that a lonely person’s immune system responds differently to fighting viruses, making them more likely to develop an illness.
Movement of water where density increases underwater causes deep currents please select the best answer from the choices provided t f
True
Yes, it is true that movement of water where density increases underwater causes deep currents.
Why does movement of water where density increases underwater causes deep currents?With the intervention of two primary mechanisms, winds and density differences, whose origin lies in the contact surface between the atmosphere and the sea, ocean mass is constantly shifted and mixed by more or less fast motions. Despite being slow, the movements of the deep ocean masses are nevertheless considered currents since they pull the water in a specific direction. Differences in density, which are influenced by salinity and temperature, are the cause of this movement.What happens to water's density as salinity levels rise?As the water's salinity increases we can observe its density increase.What are underwater deep currents?Different water densities lead to deep currents, also known as thermohaline circulation. These currents are caused by the sinking of cold, thick water at the poles. Water from the surface circulates on a 1000-year journey around the globe as it flows to replace water that is sinking.To learn more about underwater deep currents visit:
