Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!

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?
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.

Which do scientists link to increased hurricane strength?
O A. Higher ocean temperatures in the arctic
B. Higher land temperatures in the arctic
C. Higher ocean temperatures in the tropics
O D. Higher land temperatures in the tropics
Answer:
Higher ocean temperatures in the tropics
Explanation:
apex :)
Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.
What is hurricane strength?Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.
Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.

What is the difference between reproduction and heredity?
Reproduction is the process of passing on traits, whereas heredity is the process of
producing offspring
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Reproduction always involves changes in inherited characteristics, whereas heredity
does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not
Answer:
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Explanation:
PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!
Reproduction generally means making copy of something, like giving birth/breeding, duplicating.
Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!
They definitely aren’t same!
Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.
What do you mean by heredity?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

C. A decrease in the number of boa constrictors
D. An increase in the population of fruit bats
E. A decrease in the population of poison dart frogs
Answer:
A, C, E
Explanation:
If the beetles disappeared from this community, changes likely to occur include
an increase in the number of strangler figs, an increase in the population of fruit bats and decrease in the population of poison dart frogsThe beetles are insects which eat up strangler figs and a decrease mean an increase in its number.
The population of fruit bats will increase as they will have more strangler figs available for food.
Poison dart frogs will decrease because they feed primarily on beetles in the ecosystem.

Warmer climates promote higher biodiversity, allowing plants to grow year-round. This supports more organisms that rely on plants.
Colder climates promote higher biodiversity, reducing the competition among organisms for food. This supports stronger organisms that live longer.
Warmer climates promote higher biodiversity because they tend to receive more rainfall. This provides a source of water for more organisms.
Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.
