Explanation:
In 2000, Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils.
Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer’s assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues.
Next, Dr. Schweitzer looked for evidence of proteins in the T. rex tissues. She matched several samples from the fossil to parts of the modern protein collagen. Dr. Schweitzer’s discovery was so revolutionary that very few scientists believed her results. She repeated the experiment several times with great care. Each time she got the same results. In 2017, the scientific community finally accepted that proteins really could survive intact for 68 million years.
Considering the body’s organization from atoms to organ systems, in which level of organization are proteins like collagen? Describe how this level of organization fits into the organization of the whole body.

Explanation:
The level of organization in the body tells about the structural framework. According to the level of organization, proteins like collagen are categorized as molecules.
What is the level of organization?The level of organization is the structural formation that makes the whole organism and starts with a basic and smallest unit that is combined at upper levels to form the structures.
The proteins like collagen are considered molecules, as they are made of various elements, joined together by bonds. Collagen is considered the chemical level that makes the cells and further tissues.
Collagen is a structural component that further forms a cell, tissue, and organs and is involved in the transportation of oxygen, and supports bones, skin, and tissues.
Therefore, the proteins like collagen are molecule-level of organization.

Name three different factors, actions or specific human activities that contribute to the negative environmental impact in your selected area.
The selective areas are Food, Water, electricity, and clothing.
PLS Help
Answers
Certainly! Here are three different factors, actions, or specific human activities that contribute to the negative environmental impact in each of the selected areas:
1. Food:
a. Intensive agriculture: Large-scale industrial farming practices, such as monoculture, heavy use of synthetic fertilizers and pesticides, and excessive water consumption, contribute to soil degradation, water pollution, and loss of biodiversity.
b. Food waste: Discarding food at various stages of the supply chain, including production, distribution, and consumption, leads to significant environmental impacts. Wasted food contributes to greenhouse gas emissions, strains landfills, and squanders the resources used in its production.
c. Deforestation for agriculture: Clearing forests, especially in ecologically sensitive areas like the Amazon rainforest, to make way for agriculture contributes to habitat destruction, loss of biodiversity, and carbon emissions.
2. Water:
a. Excessive water consumption: Activities such as inefficient irrigation practices, industrial water usage, and domestic water wastage contribute to the depletion of freshwater resources. This can lead to water scarcity, ecosystem disruption, and ecological imbalances.
b. Water pollution: Improper disposal of industrial waste, agricultural runoff containing fertilizers and pesticides, and untreated sewage discharge contribute to water pollution. Polluted water bodies can harm aquatic life, degrade ecosystems, and pose risks to human health.
c. Dam construction: While dams provide benefits like hydroelectric power generation and water storage, their construction can have negative impacts. Dams alter natural river ecosystems, disrupt fish migration patterns, and can displace communities and wildlife.
3. Electricity:
a. Reliance on fossil fuels: Continued reliance on coal, oil, and natural gas for electricity generation contributes to greenhouse gas emissions, air pollution, and climate change.
b. Inefficient energy use: Wasteful energy practices, such as leaving appliances and electronics on standby, inadequate insulation, and inefficient lighting, increase electricity demand and strain energy resources.
c. Improper e-waste management: Improper disposal or recycling of electronic devices leads to electronic waste, which contains hazardous materials like lead, mercury, and arsenic. These pollutants can leach into the environment, polluting soil, water, and air.
4. Clothing:
a. Fast fashion: The production and consumption patterns of fast fashion, characterized by inexpensive and rapidly changing clothing, contribute to significant environmental impacts. Fast fashion leads to excessive resource consumption, water pollution from dyeing and textile treatments, and the generation of textile waste.
b. Synthetic fibers: The widespread use of synthetic fibers, such as polyester and nylon, in clothing production contributes to environmental issues. Synthetic fibers are derived from fossil fuels and do not biodegrade, leading to microplastic pollution in water bodies and ecosystems.
c. Overconsumption and waste: The "throwaway culture" associated with clothing leads to excessive consumption, frequent discarding of garments, and textile waste ending up in landfills. This contributes to resource depletion, greenhouse gas emissions from decomposing textiles, and waste management challenges.
Please note that these factors and actions are not exhaustive but provide a glimpse into the environmental impacts associated with each selected area.
Answer:
Explanation:
1. Food: The following are some activities that contribute to the negative environmental impact in the food industry:
-Use of synthetic fertilizers, pesticides and herbicides
-Clearing of forests and other natural habitats for farming
-Water usage and pollution due to animal farming
2. Water: The following are some activities that contribute to the negative environmental impact in the water industry:
-Dumping of toxic wastes into water bodies
-Excessive water usage
-Pollution from agricultural practices and human settlements
3. Clothing: The following are some activities that contribute to the negative environmental impact in the clothing industry:
-Use of synthetic fibers, which are non-biodegradable
-Chemical dyes and finishes used in textile manufacturing
-Fast fashion, which encourages a throwaway culture leading to more textile waste.

1) How do meteorologists know one storm from another especially if two are occurring at once?
2) If the current storm starts with an ‘H’ what are the next five storms for this year?
Answers
The naming of storms varies depending on the region and the organization responsible for tracking them. In the Atlantic basin, which includes the North Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico, the next five storms for 2023 would be named: Ida, Julian, Kate, Larry, and Mindy, in alphabetical order. However, it's important to note that storm names are not necessarily assigned in order and can sometimes be skipped or reused in future years.
Answer:
Satellites, Radars, Storm Spotters
Explanation:
Satellites: Satellites take pictures of Earth at regular intervals from space, telling us where clouds are located. Meteorologists watch these pictures over time to watch for rapidly growing clouds, a clue to a possible thunderstorm. Satellites also can tell us the temperature of the cloudsRadars: Radars send out electromagnetic waves that can be reflected back by precipitation or other objects in the air. Radars can measure the intensity, size, shape, and movement of rain, hail, or debris in a storm. Radars can also show the wind speed and direction near and inside the storm, which can indicate rotation or shear.Storm spotters: Storm spotters are trained volunteers who observe and report severe weather conditions from the ground. Storm spotters can provide valuable information about the location, structure, and behavior of a storm that may not be visible on radar or satellite. Storm spotters can also confirm if a tornado is on the ground or if there is any damageMeteorologists use these tools and techniques to distinguish one storm from another based on their location, size, shape, intensity, movement, and features. They can also compare different sources of information to verify or correct their analysis of a storm.
