type of question: true false question number even after someone has stopped drinking, bac can continue to go up until all of the ingested alcohol is absorbed into the bloodstream.
Even after someone has stopped drinking, BAC can continue to go up until all of the ingested alcohol is absorbed into the bloodstream : true.
Can BAC continue to rise even after you stop drinking?Driving under the influence is frequently defended on the theory of "rising blood alcohol." It is based on the observation that even after someone stops drinking, their blood alcohol content (or "BAC") levels continue to grow.
Following consumption of alcoholic beverages, EtOH is continuously absorbed, causing BACs to rise until the rate of elimination surpasses the rate of absorption. The quantity of alcohol in a person's bloodstream is known as blood alcohol content, or BAC, and it can be determined 30 to 70 minutes after drinking.

In the biogeochemical cycling of matter in marine ecosystems, which process converts nutrients back into the dissolved state
Answer:
The process that converts nutrients back into the dissolved state in marine ecosystems is called remineralization. This process occurs when dead organisms and other organic matter sink to the ocean floor, where bacteria and other decomposers break down the material, releasing dissolved nutrients back into the water column. Remineralization is an important part of the biogeochemical cycling of matter in marine ecosystems, as it helps to replenish the nutrients needed for primary productivity.

dominant advantageous alleles may take a long time to reach fixation in a population. why is that? 1 point because homozygous are made more common when there's inbreeding, making heterozygotes underrepresented because dominant alleles are more common than recessive alleles because you only observe dominant advantageous alleles in small populations, and drift counteracts it because the heterozygote is masking the other allele, and selection can't eliminate it easily
Some alleles (including those that are advantageous) may be lost due to genetic drift, whereas others may become fixed or reach 100% frequency.
A reduction in sampling error is to blame for this. Allele frequencies will therefore almost certainly fluctuate with each generation, but as the size of the population grows, the degree of change brought on by sampling error reduces. A new preferred dominant allele will typically spread quickly in the population because even heterozygous people exhibit the "better" phenotypic (produce more surviving offspring). Destructive alleles are inevitably rare once an advantage allele has achieved a high frequency and are therefore largely found in heterozygotes, therefore the final method to fixation occurs more quickly for an advantage recessive allele than for a advantageous dominant gene. Slower than neutral alleles, dominant weakly beneficial alleles reach fixation. We study a traditional Wright-Fisher model with one locus and two alleles. The genotype of the wild-type homozygote.

how does myosin and actin interact with each other?
A new cycle begins when the myosin reaches forward, binds to actin, contracts, releases actin, and then reaches forward once more to bind actin. Myosin-actin cycling is the term for this process.
An entire motor unit is made up of skeletal muscle fibers and neurons. Calcium is released from the sarcoplasmic reticulum when the impulse enters the transverse tubules. Myosin's head groups are moved along the actin filament in the plus end direction by its motor activity. The sarcomere is shortened as a result of this movement, which slides the actin filaments from both sides of the sarcomere toward the M line.
Actin (tropomyosin and troponin), which binds calcium and undergoes a shape shift to connect with myosin, is affected.
The myosin heads bind actin and hydrolyze ATP, which provides the energy for filament sliding. The process of turning chemical energy into movement is mediated by modifications in myosin structure brought on by ATP binding.

some bacteria have mutation that give them immunity to penicillin, while those without the mutation die off. the surviving bacteria reproduce. this means that doctors have to more carefully prescribe antibiotics. what process allows this kind of change in the bacteria population?
The process that allows this kind of change in the bacterial population is called antibiotic resistance. It occurs when bacteria evolve mechanisms to survive exposure to antibiotics.
This can happen through various mechanisms such as mutation or acquisition of resistance genes from other bacteria through horizontal gene transfer. The mutations that give the bacteria immunity to penicillin are examples of genetic changes that can confer antibiotic resistance. When the bacteria with these mutations are exposed to the antibiotic, they are able to survive and reproduce, passing on the resistance to their offspring. This leads to a shift in the population towards antibiotic-resistant strains. Overuse and misuse of antibiotics can also increase the rate of antibiotic resistance, as it creates more opportunities for the bacteria to be exposed to the drugs and evolve resistance.
