The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure disappear by step 3(this is when replication of viral nucleic acid and protein and envelope.) of the lytic cycle?
Answer:
When the virus injects it’s nucleic acid into the cell it uses the cell’s ribosomes to make virus proteins and those proteins are the main cause for the break up of the cell’s DNA.
The bacterial DNA structure will disappear because of ; The usage of the ribosomes of the bacterial cell by the nucleic acid injected by the virus.
The lytic cycle which is one of the cycles of viral reproduction is the cycle which leads to the breakup of the DNA of the cell ( i.e. destruction of the host cell and its membrane).
Therefore the yellow ring inside the bacterial cell will disappear by step 3 after which the nucleic acid is injected into the host cell by the virus .
Hence we can conclude that the bacterial DNA structure will disappear because of the usage of the ribosomes by the nucleic acid from the virus

How can changes in trophic levels affect an ecosystem’s health and stability?
Answer:
Trophic levels are part of an energy cascade that allows for energy consumption, conservation, and retention.
Explanation:
By altering trophic levels in an ecosystem, there is shift between the readily energy available within one specfic trophic system. If you remove wolves, for instance, normal prey could increase en-masse. In this way, the removal of wolves allows for an energy expansion that increases and accelerates the growth of that prey species. In their growth, they attain their energy from elsewhere, say specific plants off which they eat.
Which of the following is NOT an example of mechanical digestion? MULTIPLE CHOICE.
A. Amylase breaking down starch in the mouth
B. Churning of food in the stomach
C. Segmentation of food in the small intestine
D. Chewing of food in the mouth
Answer:
C segmentation of food in the small intestine
Explanation:
mechanical digestion occurs only in the mouth and that is the only one that does not occur in the mouth.Even though Both mechanical and chemical digestion occur in the mouth. ... The muscles in the stomach walls churn the bolus (mechanical), allowing it to mix with digestive enzymes and gastric acids (chemical). This process converts the bolus into a liquid called chyme. Digestion continues in the stomach for several hours. so c is the answer

Carbon in the ocean originates from the atmosphere.
lease select the best answer from the choices provided
true or false
Answer:
true
Explanation:
Carbon in the ocean originates from the atmosphere; that is true as the carbon in the ocean's main source is the atmosphere, where carbon dioxide (CO2) dissolves into the surface waters of the ocean through a process called gas exchange.
What is the role of carbon ?Carbon is an essential element for life on Earth, and it cycles through various reservoirs such as the atmosphere, ocean, land, and biosphere, the ocean is a major carbon sink, meaning it stores large amounts of carbon. But carbon dioxide is a greenhouse gas that is naturally present in the atmosphere, and its concentration has increased significantly over the past century due to human activities such as burning fossil fuels that harm all living organisms.
As a result, carbon in the ocean comes from the atmosphere; this is true.

Which of the following is NOT true about adaptation? A. Adaptation helps organisms survive in their environment. B. Adaptation can be a physical change in the organism.
C. Adaptation will always be the same regardless of the environment.
D. Adaptation can lead to evolution over many generations.
Answer:
c
Explanation:
Adaptation is a heritable behavioral, morphological, or physiological trait that has emerged through natural selection to preserve or improve an organism's fitness. Therefore, option (C) is correct.
What is adaptation?The term "adaptation" refers to a behavioral, morphological, or physiological trait that is inherited and has developed as a result of natural selection to maintain or improve an organism's fitness in response to a specific set of environmental conditions. Adaptation can be thought of as a heritable trait.
One useful illustration is the capacity to conceal oneself. Camouflage is an adaptation that helps an organism blend in with its surroundings so that it is not obvious to other organisms in those same circumstances. The organism is also able to protect itself from the hostile environment thanks to its adaptations.

Which list correctly orders the forms of radiant energy by increasing
wavelength?
A. infrared light, radio waves, ultraviolet light, visible light
B. visible light, ultraviolet light, radio waves, infrared light
C. radio waves, visible light, ultraviolet light, infrared light
D. radio waves, infrared light, visible light, ultraviolet light
Answer: Option D.
radio waves, infrared light, visible light, ultraviolet light.
Explanation:
Radiant energy is energy electromagnetic radiation that travels by waves or particles. It is measure in Joule. There are different type of electromagnetic radiation and they are defined by the amount of energy, photons and wave lengths.
Radio waves have photons with low energies and wavelengths, microwaves have little, infrared waves have more than the two, ultraviolet have more, x rays have more energy photons and wavelengths, then gamma rays have more.
Explain why decomposers are an important part of a food chain.
Answer:
Decomposers are vital to the food chain because they help recycle nutrients back into the system.
Explanation:
Decomposers like fungi and bacteria play most important role. They break down material that are dead or unused and turn them into nutrients in the fields or soil that plants use to grow.
Answer:
Decomposers are the organisms which change over complex materials into less difficult ones, often changing organic materials into inorganic ones. This, in turn, makes those assets available for use by other organisms. Decomposers, then, are crucial to the cycling of supplements in the ecosystem.

Answer:
If a cell in our body dies ( replacement and repair ) then it can cause individual cell death and if sufficient cells are lost, the result can be tissue or organ failure, ultimately leading to death of the organism.
Explanation:
Answer:
Cell Damage and Tissue Repair. Toxic damage to cells can cause individual cell death and if sufficient cells are lost, the result can be tissue or organ failure, ultimately leading to death of the organism. ... Physical agents such as heat and radiation may damage a cell by coagulating their contents (similar to cooking).
Explanation:
A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis) within a single coding section of DNA. Mistakes can also occur in the transcription of mRNA or the translation of a polypeptide. However, these changes are not considered to be mutations, because they are not permanent changes to the cell. Explain why "mistakes" in transcription or translation are not as serious as mutations in a gene.
Answer:
The cell has an elaborate mechanism in place that check for and correct the mistakes that happen during replication, transcription or translation. This process is called as proofreading. The incorrect nucleotide added during replication cause the replication to be halted for a while. The DNA polymerase enzyme fixes the error and replication then resumes as normal.
Gene mutation, on the other hand, is a permanent change in the DNA sequence that might lead to cancer.

how are the inorganic and organic fertilizers important in agriculture?
Answer:
It helps grow food and large amounts of it to feed the nation!
Explanation:
Fertilizer maintains the soil fertility, so the farmer can continue to grow nutritious crops and healthy crops. Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Most farmers today use fertilizers that are either mined or manufactured.
Answer:
In addition to releasing nutrients, as organic fertilizers break down, they improve the structure of the soil and increase its ability to hold water and nutrients. Over time, organic fertilizers will make your soil–and plants–healthy and strong.
