3 ways in which our atmosphere is not like a greenhouse
( HELP ME PLEASE)!!!!
Answer:
1.) The atmosphere is an open system, with heat energy always escaping to space. Unlike the glass it absorbs 95% of the UV in the creation of ozone. This sounds insignificant, but one scientist argues variation in the 5 percent is the cause of warming.
2.) There are no winds in a greenhouse. In the greenhouse and in the atmosphere energy is partly transferred from the heated surfaces through collision between air molecules (conduction). However, in the atmosphere a large portion of that heat is transported vertically by rising air currents (convection), and also horizontally by advection or commonly wind. There are no winds in a greenhouse.
3.) Heat reduction in a greenhouse requires a physical change with a vent to let LW escape or a screen to block SW entering. Clouds are nature’s screen. However, they can block SW and LW, such that we have little idea how clouds work to modify temperatures
Explanation:
The basic idea of a greenhouse is that sunlight or shortwave (SW) energy passes through the glass and heats surfaces. The surfaces radiate that heat as longwave (LW) energy or sensible heat (heat you can feel). LW cannot pass through the glass, so is trapped and raises the temperature in the greenhouse; the glass acts like a one-way valve. A greenhouse is a closed system because the heat cannot escape unless artificially changed by opening vents or blocking sunlight. The glass supposedly represents the entire atmosphere. It also blocks 100 percent of the ultraviolet (UV) portion of the sunlight.

i'm working on a lab report on water erosion on edg lol
pls help i'm so behind
is it okay??
Some facts about Water erosion :
Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. ... Water erosion wears away the earth's surface. Sheet erosion is the more-or-less uniform removal of soil from the surface.
Water and Wind Erosion (cause)
Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.

What are the 4 steps of mitosis? What occurs during each?
Explanation:
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin The order of the stages of mitosis can be remembered using the mnemonic PMAT.

What is adaptation? What are the two types of adaptation? Give an example each.
Answer:
adapting can be learning from your environment and ways to survive etc.
Adapting can also go to sexual reproduction to survive diseases unlike asexual reproduction.
An adaptation is a trait which increases the relative fitness of an individual. The fitness of an individual has 3 components: 1. Probability of survival to reproductive age. 2. Probability of attracting a mate. 3. Average number of offspring. Any trait which increases the fitness of an individual by positively impacting one of these three aspects is considered an adaptation.
There are 2 types of adaptation: physical and behavioral. These are self-explanatory. Physical adaptations could include things like adaptations to morphology or physiology of an organism. Behavioral adaptations are adaptations to, well . . . behavior :)

A heritable change in a person's genetic makeup is referred to as a mutation. Changes can be substantial or negligible. Chromosomes or chromosome parts may be lost, added, duplicated, or rearranged in significant alterations. Thus, option B is correct.
What mutation in a gene results in an animal?High-energy sources like radiation or chemicals in the environment can both result in mutations. They may also emerge on their own during DNA replication. The two main kinds of mutations are chromosomal abnormalities and point mutations.
Mutations can alter an organism's phenotype, which is its outward appearance, or they can have an impact on the way DNA encodes the genetic information (genotype). When mutations happen, they might kill an organism completely or only partially.
The likelihood that a gene mutation will cause an animal to be unable to produce the protein necessary for muscles to contract is that the animal will perish before producing any progeny.
Therefore, The animal will die before having any offspring.

Based on the living things in the pyramid, please tell me what examples would fit into these categories:
Primary Producers, primary consumers, secondary consumers, and tertiary consumers.
Answer:
Primary producer = Oak tree leaves
Primary consumer = Caterpillars
Secondary consumer = Blue j a y s
Tertiary consumers = Hawk
Explanation:
An energy pyramid is a graph which shows how energy is transferred or flows from one trophic level to the next. Organisms which occupy the same level in the food chain within an ecosystem belong to the same trophic level.
The shape of an an energy pyramid is a pyramid indicating that the number of living things as well as the amount of energy flow decreases as one goes from one lower trophic level to the next higher level.
At the base of the pyramid are the primary producers which use energy of the sunlight to manufacture their own food. Example is the Oak tree.
The next higher level is the primary consumers who feed directly on the primary producers. For example caterpillars.
The next higher level is the secondary consumers who feed on the primary consumers. For example the Blue j a y s.
The highest levelin the pyramid is the tertiary consumers who feed on the secondary consumers. For example, the hawk.
A researcher studied the development of resistance to antibiotics by bacteria. She studied several antibiotics to determine how long it took for bacteria to develop resistance. She found that, on average, it took eight years for bacteria to develop resistance to an antibiotic. In some cases, bacteria developed resistance to an antibiotic within a year, and none of the antibiotics were still completely effective on bacteria after 30 years.
How is this possible?
Answer:
See Explanation
Explanation:
Antibiotic resistance is said to have occurred when a given antibiotic drug is no longer effective against the target organisms. This is as a result of genetic mutation in the organism that enable resistance to the drug.
When a drug is being used against a particular organism, the organism gradually develops genetic mutations that helps it to inactivate the antibiotic drug and increase its chances of survival. These traits are passed on to offspring, hence the onset of resistance to antibiotic drugs.
There are different mechanisms of antibiotic resistance which include; Degrading the antibiotic drugs by the use of enzymes secreted by the organism, altering proteins present in the organism upon which the antibiotic drug acts and changing membrane permeability to antibiotic drugs.
