The mass extinction that led to the loss of 96% of marine life and 70% of terrestrial life was most likely due to a supernova an Asteroid impact or Volcanic eruption.
What do you mean by Volcanic eruption? How does it occur?When lava and gas are released from a volcano, often explosively, this is known as an eruption. A "glowing avalanche," which occurs when recently erupted lava slides down the flanks of a volcano, is the most hazardous type of eruption. They are swiftly moving and can withstand heat up to 1,200 degrees Fahrenheit.
Deep within earth it is so hot that some rocks slowly melt and become thick a flowing substance called magma.

Which taxonomic group of land plants, still in existence today, was the dominant group of land plants when the angiosperms began their rapid increase in speciation and distribution?
When the angiosperms started their rapid expansion in diversification and range, the dominant group of terrestrial plants—the gymnosperms—was still in existence.
Gymnosperms predominated between 252.2 million and 66 million years ago, during the Mesozoic Era, giving origin to numerous of the modern families (Pinaceae, Araucariaceae, Cupressaceae). Gymnosperms dominated the environment in the early (Triassic) and middle (Jurassic) Mesozoic epoch. Gymnosperms had been eclipsed as the most common plant class in the majority of terrestrial biomes by angiosperms by the middle of the Cretaceous (approximately 100 million years ago). The increase in angiosperm variety that occurred throughout the Cretaceous epoch led to the replacement and frequently extinction of gymnosperms and ferns.learn more about Gymnosperms here: https://brainly.com/question/16166196

Which of the following describes and example of a positive feedback loop?
A. When we are kids, our heart rates are really slow and they just continue to get
faster and faster as we grow older. We are adding to the set amount every day.
B. During childbirth, females release oxytocin, a hormone that intensifies contractions. More contractions equals more oxytocin and this cycle continues until the child is born. The body adds more and more oxytocin.
C. When we eat a donut, our body works to add more and more sugar to our blood. We want to continue to increase the amount of sugar in our blood to stay
healthy
D. When we eat a donut, our body works to pull the sugar out of our blood to ensure we have the proper blood sugar levels. If we don't eat for awhile, our body works to add sugar from our reserves into our blood to ensure we have proper levels.
Answer:
B
Explanation:
B is correct because the hormone oxytocin is doing something beneficial for both mom and baby, and will stop once the labor is over.

In the structure of the neuron, the __________ receives messages from other cells.
The correct answer is Dendrite.
A useful analogy is to think of neurons as trees. Neurons consist of three main parts: dendrites, axons, and cell bodies or cell bodies (see diagram below), which can be represented as branches, roots, and trunks of a tree, respectively. Dendrites (branch) are where neurons receive input from other cells. The dendrites branch like branches toward the tip and even have leaf-like structures called spines.
Axons (tree roots) are the starting structures of neurons. When a neuron wants to talk to another neuron, it sends an electrical message, called an action potential, across the axon. The cell body (tree trunk) contains the nucleus, houses the neuronal DNA, and makes proteins for transport down the axons and dendrites. Both the brain and spinal cord have different types of neurons. They are generally classified based on where they originate, what they project to, and what neurotransmitters they use.

Which term best applies to the study of interactions between sharks and their biological and physical surroundings?
The study of interactions between sharks and their biological and physical surroundings is called Ecology.
What is ecology?
The German naturalist Ernst Haeckel is credited with inventing the term ecology, which he used to describe the "relation of the animal both to its organic as well as its inorganic surroundings."
It is the study of how organisms and their surroundings interact. Expanding populations, food shortages, environmental pollution, including global warming, extinctions of plant and animal species, and all the accompanying sociological and political issues are some of the most urgent issues facing humanity today. These issues are largely ecological.
Relationships between organisms and their surroundings can take many different forms. Individuals, groups of individuals, the entirety of a species, the sum of several species, or the overall mass of species (biomass) within an ecosystem can all be considered organisms. Additionally, in addition to physical and chemical components, the term "environment" also refers to the biological environment, which also includes additional creatures.
The relationship between shark and their biological environment such as temperature, salinity, light, etc. makes them adjustable to the environment and hence the term is said to be ecology.

A serious environmental hazard, acid mine drainage is the result of the chemical weathering of pyrite that yields sulfuric acid and iron oxide that will degrade aquatic habitats.
Mine drainage is created when pyrite, an iron sulfide, starts reacting with air and water to produce sulfuric acid and iron oxide.
Both of these chemicals are released into the water and pollute the aquatic bodies.
The increasing amount of sulfuric acid and iron oxide is affecting aquatic and marine life badly.
In places where the concentration of sulfuric acid is high, burns the skins of marine animals.
Moreover, mine drainage also contaminates the drinking water slowing down the growth and reproduction of the aquatic plants and animals.

How many moles of electrons are required for a denitrifying organism to reduce 36 moles of nitrate (no3-) to dinitrogen gas (n2)?
180 moles of electrons are required for a denitrifying organism to reduce 36 moles of nitrate (no3-) to dinitrogen gas (n2).
The reaction of denitrification is:2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O
From the above equation:2 moles of nitrate = 10 moles of electrons36 moles of nitrate = 36×2/10 = 180 moles of electronsNitrate and nitrite are converted to gaseous forms of nitrogen, mostly nitrous oxide (N2O) and nitrogen, through the microbial process of denitrification (N2). Numerous microorganisms have the ability to denitrify. When the oxygen (O2) level in their immediate environment changes, denitrification occurs.The entire conversion of nitrate to molecular nitrogen often involves a number of bacterial species, and more than one enzyme pathway has been found in the reduction process.Complete denitrification has an impact on the environment because nitric oxide and nitrous oxide, two intermediates in the process, are important greenhouse gases that combine with sunlight and ozone to form nitric acid, a component of acid rain.Therefore, the correct answer is 180 moles.

What type of channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters?.
Voltage-gated Ca²⁺ (calcium) channel opens in response to an action potential arriving at the axon terminal and functions to allow synaptic vesicles to release neurotransmitters.
Voltage-gated calcium channels open in response to the wave of depolarization brought on by the action potential at the axon terminal. Neurotransmitter-containing synaptic vesicles undergo exocytosis when calcium reaches the axon terminal, releasing its contents into the synaptic cleft.
Action potentials are formed when a neuron gets stimulated causing a local depolarization in the cell membrane. This local depolarization triggers adjacent areas of the cell membrane to depolarize, and this continues creating a wave of depolarization traveling in one direction down the axon, called an action potential. As the action potential arrives at the axon terminal, specialized channels allow for the propagation of the action potential across the synaptic cleft to the adjacent neuron.
