In science, we have been studying the physical and chemical changes, along with the evidence of chemical reactions. Based on your understanding, write 12 - 15 sentences about the following scenario.

Oh no! Someone/something has gotten into your science kit… the box is open with the cardboard ripped up and science equipment is smashed all over the floor. The microscope is broken into 7 pieces, shattered glass is everywhere from the broken test tubes, the direction page is all crumpled up, and there is a weird greenish looking mixture that is bubbling, smoking, and burning a hole through the floor. What happened??

Consider what we have been learning in class about chemical and physical changes. Explain whether what happened to your science kit was a physical change, chemical change, or both. Use evidence from the description to defend your answer and clarify the difference between physical and chemical changes. What evidence can you look for to determine if a chemical reaction has taken place?

Answers

Answer:

If a chemical reaction has taken place you will be able to tell because of the way to chemicals react with each other

Scenario
The global population has increased immensely over the last two centuries. Humans use fossil fuels to do a variety of tasks from heating their homes to travel to production of everyday products. As the human population has increased, so have the global fossil carbon emissions.

Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:
Evidence:
Reasoning:

Answers

Answer:

The earth would eventually become become a brown and grey wasteland and the blue sky and rainbows and things like that will be rare rain would be highly acidic

Claim: my claim is that the amount of carbon emissions greatly decreased.

Evidence: There are less people which means less cars will be driven less oil will be used etc. also fossil fuels are non renewable resource which means fossil fuels will be harder to find overall diving up prices of gas,heating,etc which might make Deter people from using fossil fuels and switching to something cheaper. At this point to people will dislike fossil fuels more then now.

Reasoning: I think people won’t like fossil fuels for 2 good reasons. First the driven up price. Second there will be noticeable effects from fossil fuels it 2050. It can make crops harder to grow which could lead to famine and a Recession because driven up food prices and it will hurt the economy. Towns will slowly flood. Arctic species will die so on. So a poor family’s that can’t afford food won’t spend more money on something that overall hurts them. They will despise people who use fossil fuels and it will become socially wrong. Civilization at that time might also be working on them self. Population decreased a major amount. Something bad happened. And if what ever caused the decline in population was caused by humans which there’s no way to tell, they might try to improve human habits try not to begin wars, work on helping each other, and most importantly don’t harm there plant.

Anabaena, a strain of cyanobacteria, could help humans on Mars by producing oxygen via photosynthesis.

How important can this nonplant organism known as anabeana help in the effort for human involvement in Mars?

Anabaena can fix atmospheric nitrogen, aiding Terraforming efforts on Mars. Pollination is not present on Mars.

Pollinators like bees, butterflies, birds, and bats are vital for fertilizing flowering plants by transferring pollen, allowing for reproduction. This creates fruits, seeds, and nuts, supporting plant species and providing resources for humans and wildlife. "Mars lacks biodiversity and ecosystem dynamics to support pollinators."

Why are coconut trees found in coastal areas?

Answers

The warm, humid climate near the ocean is ideal for coconuts, which require constant moisture. Coastal locations also provide easy access to water, whether from rainfall or seawater absorption through the roots, to keep the coconut palms hydrated. Sandy soil, abundant at the coast, allows the coconuts' extensive root systems to spread and helps retain moisture.

In addition, coconut palms are well-adapted to withstand salty winds and wind-borne salt spray from the ocean, bending but not breaking in strong storms. Their flexible trunks and fan-like leaves help them cope with windy conditions.

Coconuts near coastal areas provide ecological benefits as well. Their root systems stabilize beach soil and reduce coastal erosion. Coconut palms offer shelter and food for coastal wildlife like birds and crustaceans.

In summary, the combination of warm, moist air; access to water; suitable soil; and ability to endure coastal weather make seaside locations a coconut palm paradise where these trees can thrive.

__________________________________________________________

Coconut trees are found in coastal areas because they thrive in tropical climates with high humidity and abundant rainfall.

When reading about the history of science, you often learn about individual people and the amazing things they discovered or invented. However, when learning about experiments from long ago, you might not agree with the methods used at the time. If scientists repeated the experiments today, they would probably make some changes in how they are carried out.

Priestley’s experiments, for example, were a remarkable breakthrough in the understanding of photosynthesis. He helped show an important relationship between plants and animals. However, his experiments resulted in the death of a lot of mice.

Answer one of the following prompts to begin your discussion:

Do you think that the results of Priestley’s experiments were important enough to make it okay that so many mice were killed in his experiments? Why or why not?
If you could do the experiment again, how would you design it so that you could reach the same conclusions without harming any animals?

Photosynthesis sustains aerobic life on Earth, and Joseph Priestley first demonstrated this in the 18th-century Bellger experiment with mice and mint plants. To demonstrate the fragility of life on Earth, Priestley's experiment was recreated by placing humans in a modern-day bell his jar.

After 48 hours, the oxygen concentration in the reservoir had risen to 18.1% of his, and the subject's hypoxemia was alleviated (arterial blood oxygen saturation increased from his 86% at the beginning of the experiment to his increased to 99%). Carbon dioxide levels increased up to 0.66% during testing.

This simple but unique experiment highlights the importance of plants in Earth's ecosystems by demonstrating our dependence on restoring and maintaining oxygen levels to support aerobic metabolism. increase. Without plants in sealed enclosures, oxygen levels would have dropped and carbon dioxide levels would have risen to levels unsustainable for human life.

Opinionated question 1. Many plants like soy bean and corn have been selectively bred. Do you think this is acceptable?? why or why not???

Opinionated question 2. Do you think humans should have selectively bred dogs? Why or why not?

Thanks.

Answers

Answer:

1. No, because by selectively breeding the plants you are causing the population to be very similar and could possibly not allow the plants to benefit at all times from environmental factors that could cause them health risks.

2. No, because by not selective breeding dogs we allowed for their to be a larger population of different dogs which allows some to be good at a specific thing and others not to be. This allows variety and genetic diversity allowing us to choose which dog we want/need for different things like work or just to have.

What best describes ribosomes?

Answers

Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.

Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.

An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.

Answer:

A ribosome is a intercellular structure made of RNA and protein
