a) In a food chain, arrows show the movement of nutrients or energy from one organism to another. It refers to the direction of transfer of energy or nutrients from the organism being consumed to the organism consuming it.
b) The producer in the diagrammatic food chain is lettuce, followed by green fly, ladybug, thrush and cat. Producers—also called autotrophs—are living things that can make their own food through photosynthesis or chemosynthesis, the process by which sunlight or inorganic substances are converted into energy-rich organic molecules.
c. Ladybird is the third trophic level of the food chain. The term "trophic level" describes the place an organism occupies in a food chain or web, from where it obtains its food and energy. In this scenario the greenfly is the primary consumer at the second trophic level, while the ladybird is the secondary consumer at the third trophic level. Lettuce is the first trophic level in this scenario (producer).
d.Cat is the third largest consumer in the provided food chain. In a food chain or web, tertiary consumers are those species at the highest trophic level. Typically, they are carnivores that prey on other carnivores or secondary consumers.
e) Sun is the primary energy source that powers the food chain. Most ecosystems get their energy mostly from the sun. As the species consumes and is consumed by other organisms, it is passed along the food chain after being captured by producers (such as plants) through photosynthesis.

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.

B. High temperatures during the disruption caused damage to parental somatic cells resulting.
C Exposure to radiation during the disruption caused damage to parental gametes (sex cells) resulting in mutations in newborns.
D. Exposure to radiation during the disruption caused damage to parental somatic cells resulting in mutations in newborns.
Answer:
The correct answer is choice (B) the
production of proteins. Choice (A)
is incorrect because mitochondria
produce energy for the cell. Choice (C)
is incorrect because the cell membrane

from a cell. Choice (D) is incorrect
because lysosomes break down
chemicals.
Explanation:
C. Exposure to radiation during the disruption caused damage to parental gametes (sex cells) resulting in mutations in newborns is a valid claim that can be made about how the nuclear disruption led to mutations.
What is damaged by radiation while mutations in DNA?Radiation can cause mutations in DNA by damaging the genetic material, and these mutations can be passed on to offspring through the parent's gametes.
This is because radiation can cause mutations in DNA by breaking the chemical bonds that hold it together or by causing other types of damage that alter the sequence of nucleotides. Since gametes are the cells that are involved in reproduction and pass on genetic material to offspring, mutations in gametes can be passed down to future generations.
Somatic cells, on the other hand, are the cells that make up the body of an organism but are not involved in reproduction. Mutations in somatic cells can lead to health problems for the individual but are not passed down to offspring.
Therefore, in this scenario, exposure to radiation during the nuclear disruption likely caused mutations in the gametes of the local wildlife, which were then passed down to their offspring resulting in genetic mutations in newborns.

Identify two specific populations that most likely increased in number after the mountain lion population decreased. Explain why.
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.

Answer:
Distribution structure is the distribution of individuals among various age groups in a population.?
Explanation:
agonists generally _______ activity at the synapse while antagonists generally ______ activity at the synapse.
Agonists activate the receptor thereby increasing activity at the synapse while antagonists generally prevent agonists from activating the receptors thereby decreasing activity at the synapse.
An agonist is the component that has the ability to increase the activity carried out by another substance.The agonists work from their faculty of coupling to a cell-type receptor, in this way, they manage to generate a certain action in the cell.The antagonists are the compounds that cause the opposite when they bind to the receptor, they cause a blockade by decreasing the activation of a synaptic receptor.Therefore, we can conclude that agonists are compounds capable of increasing the action of synapse and blockers (antagonists) decrease activity at the synapse.
