List the layers of the Earth in order from least dense to most dense.
Answer:
Crust, mantle, outer core, and inner core
Explanation:
inner Core-A-Solid&4300-6700°C-Most Dense Outer Core-B-Liquid& 3700-4300°C Mantle-C-Plastic& 1000-3700°C Crust-D-Rocky & 0-1000°C-Least Dense SG # 12 & 15
The layers of the Earth from the most dense to the least dense are:
Inner CoreOuter CoreLower MantleUpper MantleCrustDensity is how much mass an object has for each unit of volume. This just means how much space something takes up compared to the amount of matter that it has. When something has a lot of mass compressed into a comparatively small space, we can say that object has a high density or that it is very dense.
The Core of the Earth is divided into an inner core which is the densest, and a slightly less dense outer core. Both of these are made of iron, nickel, sulfur, and oxygen. The mantle is also divided into two parts, an Upper and a much thicker Lower Mantle. The Lower mantle is denser than the upper mantle. These layers are made of silicate rock. The most superficial and least dense layer of the Earth is the Crust.
Therefore the layers of the Earth from most to least dense are the Inner Core, Outer Core, Lower Mantle, Upper Mantle, and Crust.

True or False: Animals that eat meat benefit from plants.
Answer:
True
Explanation:
The animals they eat most likely eat (or eat something that eats) plants, making them a larger meal. If there were no plants, the wouldn't be herbivors, and without herbivors, no carnivors
Answer:
False
Explanation:
No animal is benefit from a plant not a Animal that eats meat anyway.
Animals that eat plants exclusively are herbivores, and animals that eat only meat are carnivores. When animals eat both plants and meat, they are called omnivores.
As you have observed, animal hairs usually have a large medulla composed of air-filled compartments. These air-filled compartments are present for a reason and can actually help hair do its job better. Describe one reason that might explain why having a hair made of air filled compartments could be helpful to an animal.
PLEASE HELP
Answer:
to provide insulation
Explanation:
The medullary index is the proportion of the diameter of the hair medulla in regard to the diameter of the entire hair: The equation to calculate the medullary index is medulla diameter/hair diameter. In animals, the hair medulla is generally thicker compared to humans (medullary index approximately 0.5 and 0.33, respectively). The thicker the diameter of the hair medulla, the better is the insulation.

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. Select one location to collect water samples in the pond. Collect a 5-mL water sample at 8 am for two days. Measure the amount of pesticide present in each sample using the same measurement tools. After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not reliable? The pesticide measurements were the dependent variable. The samples were collected at different times. The samples were only collected for two days. The time of sample collection was not an independent variable.
Answer:
The pesticide measurements were the dependent variable
Explanation:
According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:
- Select one location to collect water samples in the pond.
- Collect a 5-mL water sample at 8 am for two days.
- Measure the amount of pesticide present in each sample using the same measurement tools
However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.
Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.
The muscles of a tired jogger begin to undergo lactic acid fermentation. As a result, the jogger is most likely to
A) absorb more oxygen with each breath
B) release less carbon dioxide with each breath
C) experience an increase in blood pH
D) experience a “burning” sensation in the muscles
Answer:
D: experience a “burning” sensation in the muscles
Explanation: Based on the information in the lesson, this option makes the most sense.
"When lactate builds up, the blood’s pH drops and the muscles fatigue. This is why you may feel your muscles "burn" from the buildup of lactic acid."
In the given scenario, the jogger will experience a “burning” sensation in the muscles. The correct option is D.
What is muscle fatigue?Muscle fatigue is the loss of a muscle's capacity to create force. It can be caused by strenuous exercise, but abnormal fatigue can also be caused by impediments to or interference with the various stages of muscle contraction.
When lactate levels rise, the pH of the blood falls and the muscles fatigue. That's why individuals may feel their muscles "burn" as lactic acid builds up.
Thus, the correct option is D.

where do inherited traits come from and where do acquired traits come from (2 answers) ANSWER GETS BRAINLIEST!!!
Answer:
Inherited traits come from family members and are in your dna and Aquired traits you learn so are from other people.
Explanation:
Answer:
parent to offspring and during life
Explanation:
1. An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.
2.Acquired traits develop during life (organism is not born with it) . Animals learn these when they interact with environment. It is not in your DNA. It will not be passed on to next generation.

predict the likely effect on the ability of substance L to enter the cells if substance L is attached to a large protein
Full Question Attached
Answer:
The substance would be less likely to enter the cell by active transport or might enter more slowly
Explanation:
The information in the question suggests substance L is moving into the cell by active transport. We can tell this because the concentration of substance L inside the cell is 120 mM. However, the substance is still entering the cell from a lower to a high concentration, against its concentration gradient. This requires energy and is therefore active transport.
If there was a large protein attached, the active transport machinery might not be able to move substance L at the same rate. The rate it enters the cell might slow down, or it might stop all together. It might need to enter via another mechanism, such as endocytosis.

Answer: Haiti is mainly know for their minerals! the main minerals extracted are: cooper, silver, and GOLD. Haiti has many many gold farms, markets, etc. HOWEVER this is a very poor area, as people here live off of only about 2 dollars per day. They could take this wealth and put it towards the people, roads, and construction, as they had an earthquake that killed many many people, and destroyed much. If you mean what they do with gold, they take the gold from farms, and mine it underground. They then sell it for money as this is a poor area as said before!
