there are 3 ways that thermal energy can be transferred below write a paragraph describing each one with an example
Answer:
Thermal energy can be transferred by conduction, convection or radiation
Explanation:
Thermal energy is the energy that flows from one point to another due to temperature differences between the points. There are three ways by which thermal energy is transferred which are conduction, convection and radiation.
In conduction, thermal energy is transferred in solids usually metals due to their good heat conductivity. An example is seen in the use of metals for preparing meals. Heat (or thermal energy) is transferred from the fire to the metal to the food.
Convection occurs in fluids (liquids and gases). It usually occurs in a cyclic manner. For example in heating water, thermal energy is gained by water molecules closest to the heat source (at the base of the container) and become lighter causing them to rise to the top. The molecules at the top become denser and sink to the bottom whereby they gain energy and rise in a similar manner. This repeated phenomenon occurs in a cyclic form whereby there's displacement of colder and denser molecules by warmer and lighter molecules. Another example is the occurrence of sea and land breezes.
Radiation occurs without the need of any material medium unlike conduction and convection. In radiation, heat is directly transferred from one point to the other without being transferred by molecules. This is seen in how thermal energy from the sun reaches the earth. In other words, heat is transferred in a vacuum
Which phrase should be written in the column titled "always"? have a backbone are warm-blooded are multicellular eat plants
The correct phrase would be that warm-blooded animals always have a backbone.
What warm-blooded animals?They are animals whose body temperature does not fluctuate with the temperature of the environment.
Warm-blooded animals have a system in place that ensures that the temperature of their body does not fluctuate significantly. The process by which this is achieved is called homeostasis.
Warm-blooded animals are advanced animals in the chordate group. Chordates have notochords that develop into the brain and the spinal cord in several animals.
Thus, all warm-blooded animals always have a backbone.

why might stem cells from human embryos be more useful than stem cells
from adults?
Answer:
Embryonic stem cells are more useful than the adults stem cells because;
* Embryonic stem cells have the ability to create any cell type in the human body while, the adults stem cells are more specialized( they generally make cells only from their tissue of origin).
They have the capacity to divide into additional stem cells or any kind of body cell.
What is the importance of stem cells of embryo?Embryonic stem cells can develop into any type of human cell, whereas adult stem cells are more specialized and typically can only produce cells from the tissue from which they originated.
Additionally, it is simple to produce embryonic stem cells in a lab setting. There is always the option to manufacture more cells as needed because the cells can be developed through cultures.
Since embryonic stem cells are pluripotent, they are more adaptable in scientific experiments than adult stem cells. Finding novel treatments for ailments, wounds, and organ failure is one of the possible advantages of studying embryos.
Therefore, Embryonic stem cells are more useful than the adults stem cells.

The genetic diversity is the same as species diversity.
This was written as a statement, but I'll answer it as if it were a true or false question.
Answer:
False
Explanation:
Genetic diversity is the range of different traits within a species. Species diversity is the number of different species present in a place and the amount of each of those species. The difference is that genetic diversity refers to something within one species whereas species diversity refers to multiple species within a common location, or community.

Geoffrey records the heat transfer occurring in a sample of matter as being about one half as fast as he originally predicted. He concludes that the atomic structure of this matter must be more rigid and solid, as more rigid atomic structures make the particles move less, thus decreasing the ability for it transfer heat.

Time versus Population Density Graph
a. The number of frogs will decrease in response to an increase in the fly population.
b. The number of grasshoppers will increase in response to an increase in the bird population.
c. The number of coyotes will decrease in response to an increase in the rabbit population.
d. The number of hawks will decrease in response to a decrease in the mice population.
Answer:
d
Explanation:
As the number of prey decrease, the number of predators will naturally decrease. Therefore, in option D, where hawks are the predators and mice are the prey, makes the most sensible answer.
Statement :
The number of hawks will decrease in response to a decrease in the mice population.
As per the graph, the correct answer here is that the number of hawks will decrease in response to a decrease in the mouse population, which is option D, as the rise of the predator would lead to the fall of the prey number in the ecosystem.
What is the prey-predator graph?A prey-predator graph is a graphical representation of the relationship between a population of prey and their predators, and the graph shows how the population sizes of prey and predators change over time and how they affect each other. Prey and predator populations are closely linked. When there are more prey, there is more food available for predators, so predator populations tend to increase. However, as predator populations increase, they begin to consume more prey, which causes the prey population to decrease. As the prey population decreases, the predator population may also decrease due to a lack of food. This creates a cycle of predator-prey population fluctuations that can be observed on a prey-predator graph.
Hence, As per the graph, the correct answer here is that the number of hawks will decrease in response to a decrease in the mouse population, which is option D.

how does one type of rock is transformed to another type of rock?
Answer:
This can happen through the rock cycle. But there are 3 processes which are crystalization, erosion and sedimentation, and metamorphism.
Explanation:
There are several types of rocks, but only one large furnace in which parts of a single large rock are cooked and changed into the various types of rocks. Our planet is a massive rock and a massive furnace. All rocks are divided into three categories, or classes. They're classified as sedimentary, metamorphic, or igneous, with variances in how they're generated.
I'll show you a schematic of the Rock Cycle instead of a detailed answer. It shows how one type of rock may be converted (metamorphic) into another under certain conditions. Just bear in mind that some types of rocks, such as sedimentary rocks, may form in a matter of hours, while others, such as metamorphic rocks, take millions of years to create.
