Which happens when undigested food is stored in the large intestine is that food forms waste and is excreted by the body.
The digestive system is a process carried out by the digestive organ system to process food through mechanical and chemical digestion. So food can be absorbed by the body and converted into energy. The digestive system consists of the alimentary canal and glands associated with the digestive process.
The large intestine is covered by a mucous membrane without folds except the rectum. The large intestine functions to absorb water, form faecal masses, and form mucus to lubricate the mucosal surfaces. In the large intestine, the process of digestion, both chemical and mechanical, does not occur. Therefore, food that is not digested by the small intestine and then enters the large intestine will only be absorbed by the water and then formed into feces. Stool that is formed will be pushed into the rectum periistally and then expelled through the process of defecation.

pressure waves passing through the perilymph of the cochlea compress the vestibular membrane, and ultimately displace the basilar membrane. what is true of these waves?
A) High frequency waves (high notes) depress the basilar membrane closest to the cochlear's distal end.
The basilar membrane is a stiff structural element within the cochlea of the inner ear that separates the scala media and scala tympani, two liquid-filled tubes that run along the coil of the cochlea. In response to incoming sound waves, which are converted to traveling waves on the basilar membrane, the basilar membrane moves up and down.
The basilar membrane is a pseudo-resonant structure that varies in width and stiffness, much like the strings on an instrument. However, unlike the parallel strings of a guitar, the basilar membrane is a single structure with varying width, stiffness, mass, damping, and duct dimensions along its length.

What limits cell size How can the limitation of cell size be overcome?.
A cell's surface area grows as the square of its radius as the radius rises, yet its volume grows as the cube of its radius (much more rapidly). Thus, a cell's surface area to volume ratio drops as it grows in size.
A limited amount of cytoplasm can be under the control of each nucleus. This is one of the restrictions on certain biological cells' sizes. By possessing many nuclei, certain cells are able to get beyond this particular restriction. These unique cell types have multiple nuclei.
In biology, a cell is a basic membrane-bound entity that houses the building blocks of life and is the basic building block of all other living entities. As in the case of bacteria or yeast, a single cell is frequently an entire organism in and of itself.

At what point during resuscitation is a cardiac monitor recommended to assess the baby's HR?.
The baby's heart rate should be checked once more after 60 seconds of chest compressions. The most precise way to measure heart rate while performing chest compressions is through continuous ECG monitoring.
International resuscitation guidelines for neonatal resuscitation advise determining a newborn's heart rate (HR) by using a stethoscope to listen to the precordium, feeling for pulsations at the base of the umbilical cord, or feeling the brachial or femoral pulses.
The Neonatal Resuscitation Program (NRP) and other international neonatal recommendations use predetermined HR targets of 100 and 60 beats per minute (bpm), respectively, to start PPV and chest compressions. After performing compressions and ventilations for one minute, the heart rate should be monitored again.

How does energy usually flow in Eco systems
1.08 Lab: Natural Selection
Biological evolution is the process by which populations of organisms change over time. In this lab, you were able to observe how a population of peppered moths can change based on their environmental surroundings. Why do these types of changes/adaptations occur?
Answer: These types of changes/adaptations occur in order for the peppered moths to camouflage which gives them a higher chance of surviving and producing offspring.
Explanation: When the environment changed, due to pollution, the color of the moth population shifted because light-colored moths became easier to see so they were eaten more often. The darker moths were better camouflaged and more likely to survive and produce offspring. Organisms that survive have a better chance of reproducing so the population continues to grow.

how does one side of the dna strand compare with the other side of the dna strand?
The two sides of a DNA strand, also known as the "backbone," are composed of alternating sugar and phosphate molecules. The sugar in one strand is called deoxyribose and the other strand is composed of a base, which can be adenine, thymine, guanine, or cytosine. These bases form the "rungs" of the DNA ladder and are held together by hydrogen bonds, which connect the two strands of DNA. The sequence of these bases on one strand determines the complementary sequence of bases on the other strand, which is what allows for DNA replication and the transmission of genetic information.

The composition of the moon is similar to that of the Earth's Mantle, other Meteros, and other Comets.
The story best supported by all available data, however, is that the moon formed during a massive collision between the proto-Earth and another protoplanet roughly the size of Mars, known as "Theia."
The chemistry of lunar rock samples brought to Earth by lunar meteorites and the Apollo moon landings can be used to understand the history of the Moon and its relationship to the Earth.
The moon, like the Earth, began with a thick layer of molten rock on its surface.
However, unlike the Earth, the moon's surface did not cool enough to form tectonic plates. Instead, it has a thick crust made almost entirely of feldspar, a light-colored mineral. Feldspar is the main component of the bright areas visible on the moon today, also known as the lunar highlands.

Pick one of these factors and explain what impact it has on how quickly a rock weathers.
Answer:
Thermal stress is one of the causes of weathering of rocks.
Explanation:
The disintegration or dissolving of rocks and minerals on the earth's surface is referred to as "weathering." Water, ice, acids, salts, plants, animals, and temperature variations are all weathering agents. After a rock has been broken down, a process known as erosion carries the rock fragments and minerals away. No rock on Earth is strong enough to withstand the pressures of weathering and erosion.
Weathering via mechanical means Rocks crumble as a result of mechanical weathering, also known as physical weathering and disaggregation. Water, whether liquid or solid, is a common mechanical weathering component. Liquid water, for example, can seep into cracks and fractures in the rock. Water will freeze if temperatures fall low enough. Water expands as it freezes. The ice then functions as a wedge. It gradually enlarges the fissures and breaks the rock. When ice melts, liquid water erodes the rock by taking away the microscopic pieces that were lost in the break. This particular process (the freeze-thaw cycle) is referred to as "frost weathering" or cryofracturing.
Temperature changes, known as "thermal stress," can also contribute to mechanical deterioration. Temperature changes cause rocks to expand (with heat) and compress (with cold). The structure of the rock diminishes when this occurs repeatedly. It collapses over time. Thermal stress is especially dangerous in rocky desert terrain. As the temperature varies from day to night, the exterior layer of desert rocks is subjected to repetitive stress. Exfoliation occurs when the outer layers flake off in thin sheets. Exfoliation contributes to the production of Bernhardt's, one of the most spectacular aspects of weathered and eroded landscapes. Bornhardts are towering, domed, solitary rocks that are commonly found in tropical regions.

What was Darwin's theory about the finches on the Galapagos Islands?.
Darwin's finches from the Galápagos archipelago have historical significance in evolutionary biology because they provided some of the fundamental insights into natural selection and adaptive radiation processes.
Charles Darwin discovered several species of finches that differed from island to island during his visit to the Galapagos Islands, which helped him develop his theory of natural selection. He noticed that the shape of the birds' beaks varied depending on the type of food they ate.
The Galapagos finches contributed to Darwin's understanding of natural selection.

What if a human has more than 46 chromosomes?.
If a humans have more than 46 chromosomes, they will experience trisomies.
Chromosomes are fine thread-shaped structures that contain coiled DNA chains and are located in the cell nucleus. Chromosomes function as carriers of traits that can be passed on to their offspring. In humans, the number of chromosomes in a diploid cell is 46 or 23 pairs of chromosomes.
The chromosomes consist of 44 fruit chromosomes consisting of 22 pairs of body chromosomes and a pair of sex chromosomes. When someone has more than 46 chromosomes, they will experience a disorder called trisomy. Trisomy is a chromosomal disorder in which the cells in the body have three chromosomes. The cause of this excess chromosome is associated with pregnancy that occurs in women with an older age. Women who are pregnant at an old age have hormones that can affect cell division during embryonic development so as to produce extra chromosomes..

Discuss how each mutation might affect the organism—would it be helpful, harmful, or have no effect on the organism’s ability to survive in the current environment?
Explanation:
Mutation effects can be beneficial, harmful or neutral (i.e, having no effect on the organism), depending on their context or location. Most non-neutral mutations are deleterious(harmful often in a subtle or unexpected way).
In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.

competitive inhibition vs noncompetitive inhibition
Competitive inhibitors compete for the binding site in protein with the actual ligand, whereas non-competitive inhibitors do not.
A competitive inhibitor competes with the substrate for binding at the enzyme's active site. A noncompetitive inhibitor binds at a site other than the active site.
Competitive inhibition occurs when molecules that are very similar to the substrate molecules bind to the active site and prevent the actual substrate from binding. Penicillin, for example, is a competitive inhibitor that inhibits the active site of an enzyme used by many bacteria to build their cell... In repression.
Noncompetitive inhibition, a type of allosteric regulation, is a type of enzyme inhibition in which an inhibitor binds to an allosteric site, resulting in decreased enzyme efficacy. An allosteric site is simply one that differs from the active site—the location where the substrate binds.
