Answer:
Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).
What type of carbon cycling occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas?
long-term carbon cycling
carbon storage cycling
carbon release cycling
short-term carbon cycling
Answer:
The type of carbon cycling that occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas is called the geological carbon cycle. This cycle involves the long-term storage of carbon in rocks and fossil fuels like oil, coal, and natural gas. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels.
Explanation:
The carbon cycle can be divided into two main categories: the short-term carbon cycle and the long-term carbon cycle. The short-term carbon cycle involves processes that cycle carbon through the Earth system on roughly annual/decadal timescales. This includes photosynthesis, respiration, and decomposition of organic matter. The long-term carbon cycle takes millions of years to come full circle and involves the movement of carbon between rocks, soil, ocean, and atmosphere through a series of chemical reactions and tectonic activity. Carbon is stored in rocks and fossil fuels like coal, oil, and natural gas for a long time in the geological carbon cycle. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels in both short-term and long-term cycles

Which is the practice of inserting the DNA of another species into an organism's DNA so that the organism gains a new trait?
Cloning
Gel Electrophoresis
Genetic Engineering
DNA Fingerprinting
The practice of inserting the DNA of another species into an organism's DNA so that the organism gains a new trait is called genetic engineering. Therefore, option C is correct.
What is genetic engineering?Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs.
Human insulin, human growth hormone, and the hepatitis B vaccination are examples of products produced using genetic engineering techniques. Other genetically engineered species including disease-resistant plants have also been created using these techniques.
Likewise, genes can be transferred from an animal to a plant or the opposite. GMOs, or genetically modified organisms, are another term for this. Selective breeding is not the same as the procedure used to make GE foods. Therefore, option C is correct.

The Florissant Fossil Beds in Colorado are home to several massive redwood stumps that were subjected to a special kind of fossilization millions of years ago. What service could these fossilized stumps most likely provide? (Worth 15 points)
Please answer ASAP
1. tourism
2. shelter
3. lumber
4. soil creation
The most likely service that these fossilized stumps could provide is tourism. Since they are rare and significant specimens of ancient plant life, they attract visitors from all over the world who are interested in paleontology and natural history. While they may have been useful for lumber or shelter in the past, they are now protected as part of a national monument and cannot be harvested or used for those purposes. As for soil creation, while the presence of the stumps and associated plant and animal fossils can provide insights into past ecosystems and environmental conditions, they do not actively contribute to the creation of new soil.

List 3 negative impacts does plastic pollution have on the ocean?
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.
A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.

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.

A camel is lost in the desert. It is not finding any food or water. It needs 9000 kilo calorie energy and 4 litre water daily. Its mass is 650 kg and 10% of its mass is fat. It has a water reservoir near its neck with a reserve of 312 litre water. It can live using its fat storage. 1g fat contains 9 kilo calorie energy. How long the camel can survive with it's reserve?
The correct answer to how long the camel can survive with its reserve would be 65 days.
First, let us calculate the total amount of energy derivable from the fat in the body of the animal:
Mass of the camel = 650 kgMass of fat = 10% of the total mass= 10% x 650 = 65 kg
If 1g of fat is equivalent to 9000 kilocalories of energy in the animal, then, 65 kg of fat would be equivalent to:
65 x 1000 x 9000 = 585,000 kilocalories of energyThe total amount of energy is 585,000 kilocalories and the total amount of reserved water is 312 litres:
Amount of energy required per day = 9000 kilocaloriesNumber of days 585,000 kilocalories of energy can serve = 585,000/9000= 65 days
Amount of water needed per day = 4 litresNumber of days 312 litres of water can serve = 312/4= 78 days
The water reserve can last 78 days while the energy reserve can last 65 days. Since the camel needs both to survive, it means the animal can only survive for 65 days.

A mother and father have two daughters. The daughters have some similar and some different physical features. Which statement best explains why the daughters’ physical appearance includes both similar and different features?
A: One daughter received fewer genes than the other.
B: Each daughter received a different number of genes from each parent.
C: The daughters received a random set of genes from both of their parents.
D: One daughter received all her genes from her father, and the other daughter received all her genes from her mother
C: The daughters received a random set of genes from both of their parents.
The physical appearance of an individual is determined by their genes, which are inherited from their parents. Each parent contributes half of their genes to their offspring, and the combination of genes from both parents determines the physical characteristics of the offspring.
When the two daughters inherit genes from both their parents, they receive a random set of genes from each parent, which can result in both similar and different physical features. Therefore, statement C is the best explanation for why the daughters' physical appearance includes both similar and different features.

HUMAN BODY SYSTEMS QUICK GUIDE
Circulatory : Transport gasses(oxygen,CO2) and nutrients throughout body;
Digestive: Breakdown of nutrients (food);
Nervous: Process & respond to stimuli;
Respiratory: Gas exchange;
Muscular: Movement;
Excretory: Eliminates waste to maintain homeostasis;
Immune: Defense against disease
Answer: the human body is made up of multiple interacting systems, within the systems there are 3 that really work together. for starters, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells. Working along these cells is the digestive system, the human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body which then provides nutrients that give the body energy.

What surface process powers the formation of hurricanes?

water currents, caused by uneven heating from the Sunwater currents, caused by uneven heating from the Sun
water currents, caused by fast rotation of the Earthwater currents, caused by fast rotation of the Earth
winds, caused by fast rotation of the Earthwinds, caused by fast rotation of the Earth
Answer:
Explanation:In the Atlantic and Northeast Pacific, we use the term "hurricane" to describe severe storms with high-velocity winds that rotate around a central, low-pressure core. The same type of disturbance in the Northwest Pacific is called a “typhoon” and “cyclones” occur in the South Pacific and Indian Ocean.
In order for a hurricane to form, two things must be present: a weather disturbance, such as a thunderstorm, that pulls in warm surface air from all directions and water at the ocean’s surface that is at least 80° Fahrenheit (27° Celsius). Because it is the interaction of warm air and warm seawater that spawns these storms, they form over tropical oceans between about 5 and 20 degrees of latitude. At these latitudes, seawater is hot enough to give the storms strength and the rotation of the Earth makes them spin.
Hurricanes start simply with the evaporation of warm seawater, which pumps water into the lower atmosphere. This humid air is then dragged aloft when converging winds collide and turn upwards. At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, causing it to rise as well. As the air far above the sea rushes upward, even more warm moist air spirals in from along the surface to replace it.
As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.
Eventually, hurricanes turn away from the tropics and into mid-latitudes. Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart.
Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms.
Answer:
The surface process that powers the formation of hurricanes is winds, caused by fast rotation of the Earth.The formation of hurricanes requires a combination of different factors, including warm ocean waters, moisture, and atmospheric instability. However, the primary driver of hurricane formation is the Coriolis effect caused by the fast rotation of the Earth.As the Earth spins, it causes the air and water to appear to curve as they move across the surface, which generates areas of high and low pressure. These pressure differences then create winds that move in circular patterns, which are the basis of hurricanes.So, winds, caused by fast rotation of the Earth powers the formation of hurricanes.
