Limestone is a common form of calcium carbonate. When limestone is subjected to high heat, it becomes calcium oxide and releases carbon dioxide gas. This change in limestone, at a given temperature, is an example of:

A. a physical change like the melting of ice

B. a chemical change like the rusting of iron

C. an igneous change like the melting of rock in a volcano

D. a reversible change such as hardening melted butter

Answers

The answer is C.an igneous change like the melting of rock in a volcano

The change in limestone at high temperature is an example of a chemical change like the rusting of iron.

I want us to understand that a chemical change is said to occur when there is a change in the composition of a substance. We must also note that a chemical change is not easily reversible once it occurs. New substances are formed in a chemical change.

Considering the decomposition of limestone, two new substances are formed, carbon dioxide and calcium oxide. This is a chemical change just like the rusting of iron.

Which effect does an ocean have on the climate?

Responses

There is no influence on climate from an ocean.



Rushing water from tides cools the land.



Cool ocean air causes a cool climate.

Warm ocean air causes a dry climate.

Answers

The ocean warms and cools more slowly than the atmosphere, thus coastal weather tends to be more moderate than continental weather, with fewer hot and cold extremes. Evaporation from the ocean, especially in the tropics, creates most rain clouds, influencing the location of wet and dry zones on land.

pls 3-5 sentence and then explain briefly the answer. ty

Answers

Answer:

1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.

2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.

3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.

4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.

5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.

Answer
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.

2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.

3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.

4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.

5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

Answers

A pedigree chart is used to track inherited traits through generations.

A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.

Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

A pedigree chart is used to track inherited traits.

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.

A ribosome is a  intercellular  structure made of RNA and protein

Answers

Answer:.

Explanation:

The map evidence helps explain the temperature difference between Aracaju, Brazil, and Lima, Peru, by showing the prevailing wind patterns in the region.

What evidence does the wind patterns shows?

The prevailing winds are winds that blow consistently in one direction, and in this case, they move from Brazil to Peru. As the wind travels from Brazil to Peru, it passes over the Atlantic Ocean, which has a warmer temperature compared to the Pacific Ocean.

This warmer air from the Atlantic Ocean is carried by the prevailing winds to Aracaju, resulting in a warmer average temperature in this region.In contrast, Lima is situated along the Pacific coast, where the water temperature is colder compared to the Atlantic.

As a result, the prevailing winds that reach Lima from Brazil have a lower temperature compared to the winds that reach Aracaju. This colder air from the Pacific Ocean, carried by the prevailing winds, leads to a cooler average temperature in Lima.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.

Answers

The skeletal system serves several important functions in the human body. These functions include:

1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.

2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.

3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.

4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.

5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.

6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.

The human skeleton consists of 206 bones in adults. Some of the major bones include:

1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.

2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.

3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.

4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.

5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.

6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.

7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.

8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.

These are just a few examples of the major bones in the human skeleton.

Answer:

Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:

enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.

Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC

supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.

Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:

Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.

You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.

Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.

Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.

These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.
