What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?

Answers

Answer 1

Answer:

Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.

1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice,  loss of fish stocks, birds and marine mammals, and changes in climate patterns.

2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.

3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.

4.  Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.

where did the extra chromosome in down syndrome come from?​

Answers

Down syndrome results when abnormal cell division involving chromosome 21 occurs. These cell division abnormalities result in an extra partial or full chromosome 21.

Which of the following are chemical changes? Select all correct
answers.
A. table salt dissolving in water
B. a liquid evaporating to form a gas
I C. a force causing a sheet of metal to bend
D. wooden logs burning to form ash
E. hydrogen and oxygen forming water

Answers

Answer:

D and E

Explanation:

The others are physical methods and can be separated again.

Hope this helps :)

Ashes (which are made of carbon), carbon dioxide gas, water vapor, heat, and light are produced when wood is burned. Since this change cannot be undone, it is a chemical change. Since oxygen and hydrogen unite to create a single product, Thus option D and E is correct.

What is chemical changes?

A chemical change is the transformation of one substance into another, the emergence of new compounds with distinct properties, or any combination of these.

It happens when two compounds mixes to create a new material (synthesis or either decomposes to form more substances).

Chemical synthesis, or, alternatively, chemical breakdown into two or more separate molecules, occurs when one material reacts with another to create a new substance.

These processes are referred to as chemical reactions, and they are typically irreversible barring additional chemical reactions.

Therefore, burning of wooden logs and formation of water is an example of chemical changes.

Cellular differentiation is the process of a cell going from one form to a more specialized cell.

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.

Dependent variable: Time the clock stopped

Control: None for this experiment

Constants: Same type of clock

Explanation:

Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.

Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY

Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.

Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.

Independent variable: Type of battery

Dependent variable: Time the clock stopped

Control: None for this experiment
