_____________________________________TYPES OF MECHANISMSThere are two types of mechanisms
Negative Feedback Mechanism:This mechanism opposes the change that occurs in the body resulting in the decrease of the CHANGE.
Positive Feedback Mechanism:This mechanism enhances the change that occurs in the body resulting in the increase of the CHANGE.
_____________________________________THERMOREGULATIONThermoregulation is the control of body temperature
__________________________________________________Decrease in temperatureThis picture is the mechanism for the THERMOREGULATION (control of the body temperature). It is the negative feedback, as you can see if the temperature is decreased that means the change occurs, so the process of shivering starts which is the movement of muscles which generates the heat resulting in the increase in temperature.
CHANGE: Less Temperature i.e. body cold.
NEGATIVE FEEDBACK: Increases temperature and brings it back to normal.
__________________________________________________Increase in temperatureWhen the Temperature of the body increases, that means when the change occurs, The Negative feedback mechanism is triggered resulting in the process of sweating which brings the body temperature down.
CHANGE: More Temperature i.e. Body hot
NEGATIVE FEEDBACK: Decreases the temperature by the process of sweating and brings it back to normal.

How is the water movement on wetlands? Explain.
Answers
Answer:
Water is accommodated a wetland straightforwardly when precipitation falls on the wetland or by implication when precipitation falls outside the wetland and is shipped to the wetland by surface-or ground-water stream. For instance, snow that falls on wetland bowls gives surface-water stream to wetlands during spring snowmelt.
Answer:
Many pollutants are washed by rainfall from urban and agricultural lands and are carried overland to water bodies. Pollutants include soil particles, fertilizers, pesticides, grease and oil from cars and trucks, and road salts. Wetlands can improve water quality by removing pollutants from surface waters. Three pollutant removal processes provided by wetlands are particularly important: sediment trapping, nutrient removal and chemical detoxification.As water from a stream channel or surface runoff enters a wetland, the water spreads out and flows through dense vegetation. The velocity of the flow is reduced, allowing suspended material in the water to settle to the wetland surface. The roots of wetland plants can then bind the accumulated sediments. As much as 90 percent of the sediments that are present in runoff or in streamflow may be removed if the water passes through wetlands. Also, because pollutants, such as heavy metals, are attached to soil particles, the settling of sediments in wetlands further improves water quality.Nitrogen and phosphorus from agricultural and lawn fertilizers, pet waste, sewer and septic systems, and other sources can act as plant fertilizers in natural water bodies and stimulate excessive plant, algae, and cyanobacteria growth. Such growth may produce toxic chemicals and choke out natural vegetation and wildlife. When runoff and stream flow pass through wetlands before entering a water body, these nutrients may be taken up by wetland plants and accumulate in less harmful chemical forms. When wetland plants die and decay, nutrients are recycled within the wetland. Wetlands are so effective at removing excess nutrients from water that many municipalities have built wetlands specifically for treating effluent from secondary sewage treatment plants. Natural wetlands are not suited for this purpose and for each wetland there is a limit to how much can be added before the natural plant and chemical processes are overloaded and break down.

Chromosomes line up in the middle of the cell single file line during which phase?
A.Metaphase 1
B.Anaphase 1
C.Metaphase II
D.Anaphase II
HELP ASAP
Answers
Answer:
Metaphase II
Explanation:
Chromosomes align in the centre of the cell during both rounds of meiosis. Specifically, this occurs during metaphase I and metaphase II.
During metaphase I, the homologous chromosomes line up in pairs. This makes two lines of chromosomes in the centre (not a single cell)
During metaphase II, the chromosomes line up in the centre, in a single file, and are pulled apart by the spindles, separating the two sister chromatids.

Five different types of fossils are body fossils, molds and casts, petrification fossils, footprints and trackways, and coprolites.
The types of Fossils are :
Body Fossils.Molecular Fossils.Trace Fossils.Carbon Fossils.Pseudo FossilsFossilsThe importance of fossils are :
Fossils give important prove for advancement and the adjustment of plants and creatures to their situations.
Fossil prove gives a record of how animals advanced and how this handle can be spoken to by a 'tree of life'.
The types of Fossils are :
1) Body Fossils-
Body fossils were parts of the life form, such as bones or teeth
2) Molecular Fossils-
Molecular fossils are natural atoms determined from once living organisms. Body fossils were parts of the life form, such as bones or teeth.
3) Trace Fossils-
Trace fossils incorporate foot impressions, eggs, burrows, and fertilizer.
4) Carbon Fossils-
When an living being kicks the bucket and is buried in silt, the materials that make the living being break down and in the long run as it were the carbon remains.
5) Pseudo Fossils-
Pseudofossils are inorganic objects, markings, or impressions that may well be mixed up for fossils.

Answers
Answer:
Some condons code for the same amino acid
Explanation:
U welcome
The statement that describes why the change in only one DNA base of a gene results in a different protein being produced by the gene is some condons code for the same amino acid.
It should be noted that it is possible for different codes to produce identical amino acids due to the way that they bind to transfer RNA.
Different organisms use different codons. Therefore, it's important for the gene sequence to allow for optimal usage in the human cell line.
In conclusion, condons code for the same amino acid.
