How does thermal energy affect the earth's layers?
Answer:
The thermal energy of the Earth remains from its formation and is continuously generated from radioactive decay of long-lived radionuclides in the Earths interior. The deeper the Earth layers the higher the temperature with the geothermal gradient of temperatures through the Earth’s crust on average as high as 25–30°C/km.
Explanation:
The thermal energy affect the earth's layers by forming a thermal gradient.
Thermal energy of the Earth:
Deep inside the earth the thermal energy is generated by the radioactive decay of long-lived radionuclides.
This creates a thermal gradient from core to surface of the earth. The temperature of the core is highest, then the manle is semi-solid or liquid.
The crust of the earth is solid and have relatively less temperature,
Therefore, the thermal energy affect the earth's layers by forming a thermal gradient.

Which statement best describes members of the same species?
O They possess identical numbers of cells in their bodies
O They possess identical traits and physical appearances
O They are able to breed with each other and produce offspring of different species
They are able to breed with each other and produce offspring of the same species
Answer: D.
Explanation: Members of the same species do not have the same number of cells. Think differences in height or weight. They do not have identical traits. Think siblings. They cannot create different species. Two wolves cannot make a coyote.
What are some of the WORST things about coal fuel?
help me please help me
Answer:
Explanation:
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Answer:
Air pollution
Can impact health of citizens like asthma, breathing difficulties, etc.
Can lead to death if not treated or fixed.
Releases greenhouse gases into the atmosphere.
Contributes to global climate change.
1. How many pounds of biological material is below that soil surface?
Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.

What is Sunny weather?
Sunny weather is described as the type of weather where the sky is blue, the grass is bright, and there is a lot of sunlight that is usually warm when the sun comes out, so people in cold climates find it quite looks nice. People may not be so fond of this weather.
When it comes to absorbing heat on sunny days, the color of the fabric is more important than the length or material it is made of, when compared to a black shirt with short sleeves, a long sleeve white shirt can make you feel colder because of all the colors.
So when we wrap a black paper on something like jar it will get warmer as compared to other colour papers.
Thus, a jar placed in a sunny window will get warmest if it is wrapped loosely in Black paper. So, the correct option is (G)

in which of these is osmosis occurring
1 plant is absorbing water from the soil
2sugar is being taken up into the blood from the gut
3 water is evaporating from a leaf
4oxygen is entering the blood from the lungs
Answer:
1.Plant absorbing water from the soil.
Explanation:
Osmomsis occurs by the movement of a water from a region of higher concentration of water molecules to a region of lower concentration of water molecules, through a semi permeable membrane,
OR
It occurs as a result of movement of substance molecules from a region of lower concentration to a region of Higher concentration of the substance.
Note: The higher the concentration of the substance molecules,the lower the concentration of water molecules.
The movement of water into the roots of the plants from the soil demonstrates the most valid and accurate example of osmosis. Thus, the correct option for this question is A.
What is Osmosis?Osmosis may be defined as a type of process through which the movement of a solvent such as water takes place from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane.
The absorption of sugar into the blood from the gut is mediated by secondary active transport with the help of transporters like SGLT-1 and SGLT-2. The process through which water is evaporating from a leaf is known as transpiration. The process of entering oxygen into the blood from the lungs is known as diffusion.
Therefore, the movement of water into the roots of the plants from the soil demonstrates the most valid and accurate example of osmosis. Thus, the correct option for this question is A.

Police are investigating a series of murders in which the suspect is leaving little to no physical evidence, such as fingerprints or DNA. They cannot even establish an obvious link between victims. The only real evidence they have are strange pieces of typewritten poetry found tucked into the victims’ pockets. Who might the police call on to give valuable insight to help them identify the perpetrator and possible future victims? Forensic anthropologist Forensic entomologist Forensic pathologist Forensic psychiatrist
Answer:
Forensic anthropologist
Explanation:
Forensics is a branch of science that deals with the solving of crimes. According to this question, police are investigating a series of murders in which the suspect is leaving little to no physical evidence such as DNA or fingerprint. However, strange pieces of typewritten poetry was found tucked into the victims’ pockets as evidence.
Based on this evidence found, a FORENSIC ANTHROPOLOGIST is the person that can give valuable insight to help the police identify the perpetrator and possible future victims. This is because ANTHROPOLOGY is a social science subject that deals with past events, hence, forensic anthropologists will be able to work on the typewritten poetry.

When we doing strawberry extraction,why do we have to remove the air as much as possible before we seal the bag?
Answer:
Explanation:
Oxygen is needed to support life and some metabolic processes in microorganisms especially aerobic organism.
The presence of oxygen in the container gives them the opportunity to carry out there metabolic activities thereby enhancing there growth and multiplication.
Hence, to limit the growth of aerobic bacteria or fungi, and also to prevent the evaporation of volatile components that is available in the content oxygen is withdrawn this help extend the shelf life of the produce to be stored.

B.Q and Z
C.R and Y
D.S and X
Answer:
D. S and X
Explanation:
The pair that is at the same level of structural organization is S and X.
S is the brain of human
X is the leaf of plant.
Both the brain and the leaf are in the organ level of organization. The brain is an organ in human body which carries out most activities in the body. It controls all functions of the body and also interprets information from the outside world. The brain is the seat of intelligence, emotion, creativity and memory.
The leaf in plants is a collection of tissues. It enables photosynthesis to occur. The leaf traps sunlight and carbon dioxide which are used during photosynthesis to manufacture food for plants.

Mutation Classes
Class I - Gene contains a stop signal that prevents CFTR from being made.
Class II - CFTR is made, but does not reach the cell membrane
Class III - CFTR is made and in the right place, but does not function normally
Class IV - Channel does not move substances efficiently or at all
Class V - CFTR is made in smaller than normal quantities
