when a population overshoots its carrying capacity, as you saw in the lesson of the kaibab lab activity, what typically follows?
when a population overshoots its carrying capacity, There may be no more resources left. If all of the resources are used up, populations may die out.
The world's keeping potential appears to be largely determined by a number of factors, including environmental or biological phenomena. It's possible that nutrients will be completely depleted in a community that has outlived its ability to hold on for such a long time. When a creature's population grows faster than the ecology can support it, it may become extinct. When all resources are used up, communities may slowly deteriorate. Drink, food, shelter, and energy would all be limited as humans reach their maximum capacity. In order for people to thrive, they need to be dissatisfied with the food and other factors.

Dozens of earthquakes hit Hawaii as the world's largest volcano erupts
On November 27, Mauna Loa erupted for the first time in nearly 40 years. Located in Hawaii, Mauna Loa is the world's largest active volcano. Volcanoes are openings or vents where lava, small rocks, and steam erupt onto the Earth's surface. Melted rock that comes up from inside the Earth and out of a volcano is lava. The Mauna Loa eruption occurred at the Moku'āweoweo summit caldera. This is a large sunken basin at the summit — or highest point — of the volcano.
Following the eruption, dozens of earthquakes swarmed the region — one of them a magnitude 4.2 quake. Magnitude is a number that characterizes the relative size of an earthquake from 1 to 9.
Remain Vigilant
Officials issued an ashfall advisory for Hawaii's Big Island and asked residents to remain vigilant. So far the eruption's lava flows pose no risk to people living downhill from the eruption, according to Hawaii's Tourism Agency.
Map showing lava flow of Mauna Loa from the years 1843 to 1984.
Image 1. The volcano's last eruption was in 1984, when it sent a lava flow close to the city of Hilo.
"At this time, lava flows are contained within the summit area and are not threatening downslope communities," said officials from the U.S. Geological Survey (USGS). The USGS is a government agency that collects information to help monitor natural hazards such as earthquakes. They warned, however, that the location and advance of lava flows can change rapidly.
The USGS's Hawaiian Volcano Observatory noted that it is set to perform flights to assess the eruption. They warned that "winds may carry volcanic gas and possibly fine ash and Pele's hair downwind." Pele's hair are thin strands of volcanic glass formed from cooling lava. The glass is sometimes carried into the air by strong winds and is sharp enough to tear skin and eyes.
Monitoring The Volcano
Mauna Loa takes up more than half of Hawaii's Big Island. It rises 13,679 feet (4,169 meters) above the Pacific Ocean, according to the USGS. The volcano is fairly active, having erupted 33 times since its first well-documented eruption in 1843. Its last eruption was in 1984 when it sent a lava flow close to the city of Hilo. After that, Mauna Loa entered its longest dormant period in recorded history. Periods of time when the volcano is not erupting, but could in the future, are volcanic dormant periods.
Scientists tracked an uptick in earthquake frequency beginning in June with five to 10 earthquakes a day. By September, the warning signs of an eruption increased. The number of earthquakes grew to around 40 a day in October.
The central idea that the text has is that it tells us of the fact that the scientists were talking about the eruption as a way of sending out warning to the people.

true or false: neurons have a pacemaker potential.
True. The ability of pacemaker neurons to produce rhythmic bursting activity is a characteristic feature of these cells.
Understanding how many rhythmic activity in neural networks are produced by voltage- and time-dependent ion fluxes in single neurons may be largely dependent on this phenomenon. In addition to rhythmic motor activity, rhythmically active neural networks also contribute to seemingly non-rhythmic behaviors including sleep, arousal, addiction, memory, and cognition. Pacemaker neurons are found in several of these networks. The slow, positive increase in voltage across the cell membrane (the membrane potential) that takes place between one action potential and the start of the next action potential is known as the pacemaker potential or pacemaker current in the pacemaking cells of the heart, such as the sinoatrial node.

specific adaptations that animals have developed to survive in humid subtropical climates
Answer:
Animals that live in humid subtropical climates have developed a variety of adaptations to help them survive and thrive in these conditions. Some examples of these adaptations include:
:Thick, insulating fur or feathers: Many animals in humid subtropical climates have thick fur or feathers that help to keep them warm and dry in wet conditions. This can help to prevent heat loss and maintain body temperature, which is especially important in environments where the air is cool and damp.
:Waterproof skin or scales: Many animals in humid subtropical climates have skin or scales that are waterproof or water-repellent. This helps to prevent them from getting waterlogged and can make it easier for them to move through wet environments.
:Webbed feet or other adaptations for swimming: Some animals in humid subtropical climates, such as amphibians and aquatic mammals, have webbed feet or other adaptations that allow them to swim efficiently. This can help them to move through wet environments and avoid predators.
:Behavior patterns that minimize exposure to heat and moisture: Many animals in humid subtropical climates have behavior patterns that help them to avoid the heat and moisture that can be common in these environments. For example, some animals may become inactive during the hottest parts of the day, or may seek shelter in cool, damp areas during times of extreme heat or moisture.
:Specialized digestive systems: Some animals in humid subtropical climates have specialized digestive systems that allow them to extract nutrients from wet or damp foods, such as grasses and leaves. This can help them to survive in environments where food may be scarce or difficult to access.
Overall, the specific adaptations that animals have developed to survive in humid subtropical climates vary depending on the species and the specific conditions of the environment. However, these adaptations generally help animals to regulate their body temperature, move efficiently through wet environments, and access food and other resources in these conditions.

Individuals inherit two copies of each gene from each parent, which are referred to as alleles. Only one allele of a gene will be expressed if two alleles differ; this is the dominant gene. The effect of the other, recessive allele is obscured.

Steps are in protein synthesis:
1) m-RNA
2) ribosome / r-RNA
3) amino acid
4) t-RNA
5) peptide linkage.
What is protein sysnthesis?The cytoplasm contains ribonucleoprotein particles called ribosomes, which are where protein synthesis takes place. In biology, the process of protein synthesis is crucial to cellular survival. The process through which cells produce proteins is known as protein synthesis.
Function of these steps in protein synthesis -
1) m-RNA : The function of mRNA is to transport protein information from DNA in a cell's nucleus to the cytoplasm, or watery interior, where the machinery responsible for making proteins reads the mRNA sequence and converts each three-base codon into an amino acid that belongs in a protein chain that is expanding.
2) ribosome / r-RNA: The catalytic stages of protein synthesis—the joining of amino acids to form a protein molecule—are governed by the rRNA molecules. To represent this role, rRNA is frequently referred to as a ribozyme or catalytic RNA.
3) amino acid: Long thought to as little more than protein synthesis substrates, amino acids have lately been demonstrated to operate as modulators of intracellular signal transduction pathways frequently linked to growth-promoting hormones like insulin and insulin-like growth factor1.
4) t-RNA: The primary role of tRNA is to transfer amino acids to create polypeptides in the proper order. As a result, it aids in protein synthesis. Additionally, it serves as an adaptor molecule by connecting particular amino acids to the appropriate codons found in the mRNA molecules.
5) peptide linkage: Covalent bonds between two amino acids are known as peptide bonds. Proteins are large chains of amino acids that are created by living things via peptide bonds. In addition to providing structural support, initiating significant processes, and identifying chemicals in the environment, proteins have a variety of other activities.
