Any change that occurs at any link of a trophic web will affect the other links. The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.
----------------------------
The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heterotrophs-: herbivores and carnivores. The last links are the decomposers that degrade organic matter from dead organisms.
As it is a web, all organisms are equilibrated until a change occurs.
When the change affects any of the involved links, there can be a cascade effect on the web.
A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
According to the provided trophic web, puma feeds on deer and rabbit.
Since puma was killed, their population size sharply decreased.
This fact followed the predator-prey cycle, in which the predator regulates the prey population size and vice-versa. When there is a decrease in the predator population size, the prey population increases in size because of the absence of their natural predators.
In the absence of puma, deer and rabbits increase their population size. They live in an environment with no predators and enough resources.
The number of individuals of each species increased, and the amount of food consumed increased too.
This change negatively affected grasses and grains, which were over-consumed. Also, crickets and mice were affected too because they compete for the same food source.
So, cascade effects would be as follows,
1) The decreased in the puma population size caused an increase in the deer and rabbit population size.
2) The increase in the deer and rabbit population size caused a decrease in the grains and grasses species population, because they were over consumed.
3) The decrease in grains and grasses caused a decrease in the cricket and mouse population, because they feed on the first ones, competing with deer and rabbits for food.
The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.

A classmate states that both energy and matter can be created during photosynthesis and cellular respiration. Is this true? Explain
Energy and matter are also produced during photosynthesis.Chemical energy in the form of glucose and matter in the form of oxygen gas are produced during photosynthesis.Since these are the results of the reaction, they are regarded as process outputs.
Can both energy and matter be created during photosynthesis?
Some cells employ a process called photosynthesis to convert light energy into food.Because it enables plants to produce the food required for the rest of the ecosystem, photosynthesis is crucial.Producing organisms, or those that grow their own sustenance, are plants.The foundation of the ecosystem is formed by producers, who transform solar energy into chemical energy in the form of food for themselves and other ecosystem inhabitants.Although many ecosystems are dominated by plants, other organisms are also capable of photosynthesis.Some bacteria and algae are capable of photosynthesizing, and these organisms are the producers in their ecosystem. A biological process called photosynthesis consumes both matter and energy.The world's physical components are made of matter.The capacity to perform work is energy.By use of various mechanisms, matter and energy can be switched for one another.On the other hand, neither matter nor energy can be generated nor destroyed.The first law of thermodynamics is that they constantly evolve into new forms.All processes in the universe operate in this manner.Energy can be transformed into a variety of forms.Several instances include:Chemical drivekinetic energythe potential energy of gravityelastic force The substance and energy persist even after an organism dies.Instead, they are changed into other forms.For instance, both matter and energy are components of plants.Fungi and bacteria in the soil aid in the breakdown of a plant's internal substance into its constituent parts when it dies.These can be used by newly sprouting plants by being recycled into the soil.As a result, neither the energy nor the substance is wasted; rather, they are transformed into new forms.To learn more about photosynthesis refer

1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. 100 points!!! Not a scam!
Answer: The sun produces energy to the solar panel the sollaer panel produces energy to my house
Explanation:
The Sun then provides energy to the grass via the photosynthesis process. The rabbit consumes the grass and absorbs its energy.
What is flow of energy?The flow of energy through living things within an ecosystem is referred to as energy flow.
All living organisms can be classified as producers and consumers, and those producers and consumers can be classified further as a food chain. Each level of the food chain is referred to as a trophic level.
The Sun then provides energy to the grass through photosynthesis. The rabbit consumes and absorbs the grass's energy.
Finally, the snake consumes the rabbit and absorbs its energy. Energy travels from the Sun and is consumed by each consumer along the chain.
Thus, this way, energy flows in an ecosystem.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
what was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?
Explanation:
DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
[tex] \mathbb \fcolorbox{green}{red}{ STAY \: STRONG}[/tex]
[tex] \mathfrak \fcolorbox{green}{red}{BE \: BRAINLY }[/tex]
In the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
What is Hershey and Chase experiment?Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.
They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.
Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNANext, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).
This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.
Thus, in the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

Describe what would occur if you turned a growing seedling on its side (without disturbing the root system.) What is occurring inside the plant, and what hormone is involved? Be specific.
Phytohormones are responsible for the movement of plant towards stimulus. Auxin is the main phytohormone responsible for gravitropism and phototropism of plants.
What is Plant Movement?Plants are immobile however different parts of the plant show movements in response to the stimulus in the environment. The chemicals present in the plant body which are responsible for these movements are called phytohormones or plant hormones.
Auxins are the main hormones responsible for the cell elongation in plants. Auxins are responsible for the phototropism (movement of plant parts in response to light) and gravitropism (movement in plants in response to gravity).
Roots of a plant grow downward and exhibit positive gravitropism whereas stems on the other hand, exhibit negative gravitropism since they grow upwards and against the gravity. If you place a plant on its side or even upside down, the stem will curve its way up in response to gravity and auxin is responsible for this movement.

On average, men have a basal metabolic rate (BMR) of 1.0 kilocalorie per kilogram per hour. Lawrence weighs 198 pounds. Calculate how much energy Lawrence expends for basal metabolism per day.
The energy Lawrence expends for basal metabolism per day is 2,160 kilocalories per day.
Basal metabolic rate is defined as the amount of energy that is used when an individual is at rest.
This energy is used for life sustaining functions such as:
breathing,circulation,nutrient processing andcell production.To calculate the Basal Metabolic Rate for Mr Lawrence,
Lawrence weight = 198 pounds
60
(convert pounds to kilogramme)
1 pound = 0.453592kg
198 pounds = x
xkg = 0.453592 × 198
= 89.8 kg
But BMR for average men = 1 kilocalorie per kilogram per hour.
That is, 1 kilocalories = 1 kg per hour
x kilocalories = 89.8 per day
Therefore for a day = 89.8 × 24 ( 24 hours = 1 day)
= 2155.469184
approximately. = 2,160kilocalories per day
