In tree rings, like those shown, each "ring" of growth represents what? A. One season of growth B. Two years of growth C. One month of growth D. One year of growth
Answer:
The correct answer is option D, that is, one year of growth.
Explanation:
Every year, the tree produces new cells, aligned in concentric circles known as annual growth rings or annual rings. These annual rings demonstrate the concentration of wood generated at the time of one growing season. The season of growth starts in the spring. Initially, the cambium generates many big cells with thin walls, which produces the springwood that appears as a light ring.
Then at the termination of the summer, growth slows down. The cells produced at the time of this year are small and comprises thick walls, the formation of summerwood takes place, which appears as a darker ring. Therefore, one year of growth is signified by a ring comprising of dark and light part.

D. trace evidence
Answer:
D
Explanation:
Trace evidence (traced back to the crime)
ANSWER:
The correct option is C: Latent fingerprints. Latent fingerprints are evidences that link a suspect to crime scene.
EXPLANATION:
Fingerprints are considered to be unique for every individual and therefore these can be used as the perfect evidence for matching a suspect to the crime scene. Latent fingerprints are the invisible image transfers of the fingerprints that can be obtained easily by applying fingerprinting powder with oil. This oil makes visible the lines and ridges that can be taken for matching the suspect with the crime scene.how does a pluripotent cell differ from a totipotent cell?

Climate Change: a change in worldwide or local atmosphere designs, specifically a change obvious from the mid to late twentieth century onwards and credited to a great extent to the expanded degrees of environmental carbon dioxide delivered by the utilization of petroleum derivatives.
Ocean acidification: the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere
Invasive Species: According to Executive Order 13112 an "obtrusive species" is characterized as an animal categories that seems to be: 1) non-local (or outsider) to the environment under thought and. 2) whose acquaintance causes or is likely to cause monetary or ecological damage or mischief to human wellbeing.
Increase In Human Population: In science or human geology, populace development is the expansion in the quantity of people in the populace.
Eutrophication: the improvement of a biological system (normally sea-going) with substance supplements (nitrates, phosphates, and so forth.)
The supplements can be presented through draining from soil by precipitation or discharged as a feature of sewage
Eutrophication is normal around horticultural terrains where the utilization of counterfeit manures are common
An expansion in supplement supply inside conduits will bring about a few biological results:
A fast development in algal populaces will happen (algal sprouts) because of the expanded accessibility of supplements
As the green growth kick the bucket, there will be a resulting spike in the quantities of saprotrophic microorganisms (decomposers)
The high rate of disintegration will bring about an expanded biochemical oxygen request (BOD) by saprotrophic microbes
The saprotrophs will expend accessible amounts of broke down oxygen, prompting deoxygenation of the water supply
Eutrophication will likewise expand the turbidity of the water, which will decrease oxygen generation by photosynthetic ocean growth
This will pressure the survival of marine life forms, possibly prompting a decrease in biodiversity inside the biological system
Deforestation: the activity of clearing a wide zone of trees.
Biodiversity: Biodiversity is under genuine danger because of human exercises. The primary risks worldwide are populace development and asset utilization, environmental change and an unnatural weather change, living space transformation and urbanization, intrusive outsider species, over-abuse of regular assets and natural debasement.

Which waste management process involves the burning of natural solid waste Answers for part 2: coal dust gas
Answer:
Incineration
Explanation:
The correct answer to the question is incineration. Incineration is a waste management process that involves the burning of waste at high temperatures to reduce its volume and mass. Natural solid waste such as wood, paper, and food scraps can all be incinerated.
Here's a breakdown of the other options:
Pyrolysis: This process involves heating waste in the absence of oxygen, which breaks down the organic material into charcoal, oil, and gas. It is not technically burning, as it happens without oxygen.
Gasification: Similar to pyrolysis, gasification also heats waste in the absence of oxygen, but at higher temperatures. This converts the waste into a synthetic gas called syngas, which can be used as a fuel.
Plasma gasification: This is a type of gasification that uses plasma torches to heat the waste to extremely high temperatures. This breaks down the waste into even smaller molecules, including hydrogen and carbon monoxide, which can be used to produce syngas or other fuels.
So, while all of these processes involve thermal treatment of waste, only incineration involves burning it in the presence of oxygen.
