In terms of reproduction, what is an example of a dependent relationship between a plant species and an animal species? What do you think would happen if the population of one of the species decreased?
A dependent relationship between a plant species and an animal species is when the population of one of the species decreases. This can happen by disease, or by loss of habitat. The result of this decrease is that the population of the other species will increase.
For example, if a plant species is plentiful and an animal species is more scarce, then it will be less likely for an individual animal to find food. This could cause an increase in death rates among animals who are unable to find enough food or food sources that are not well-suited for their diet. In turn, this loss in population would lead to fewer births as well as lower survival rates.
If the population of one of the species decreased, it would mean that there would be less plants or animals to feed off of. This could lead to a decrease in food supply for either plant or animal species. It is possible that this could cause a decrease in population as well.

If you were going to replace water as the coolant in an engine, would you look for something with a higher or lower specific heat? Explain.
Answer:
I think you would use a lower specific heat.
Explanation:
If you have a hot coffee cup and you want to cool it down place it in the refrigerator or place it in a bowl of cold water where the top is just above the water. Do not copy this down onto your question just summarize.
If one is going to replace water as the coolant in an engine, it would look for something with a higher specific heat because it would absorb more heat for each degree rise in temperature.
What is a coolant?A coolant is a fluid that is used to cool or transfer heat from one part of a system to another.
Coolant aids in the prevention of corrosion and engine rust. Coolant also protects against freezing.
It does not, like water, freeze and expand in extremely cold temperatures. This prevents cracking and increased pressure in your engine.
If water is to be replaced as the coolant in an engine, something with a higher specific heat would be preferred because it would absorb more heat for each degree increase in temperature.
While you can drive the car for a short period of time with water instead of coolant, it will not effectively protect your engine.
Thus, one should look for a material having higher specific heat for being a coolant.

Darwin introduced both microevolution and macroeveolution. He delves into two major themes both young and old evolution by natural selection microevolution and descent with modification macroevolution.
What is meant by microevoultion and macro evolution?
The process by which organisms change in small ways over time is known as microevolution. It is a change that occurs in a population due to changes in allelic frequencies. Macroevolution describes larger evolutionary changes that result in the emergence of new species. Macroevolution refers to large-scale, visible changes that occur above the level of species. The change occurs at the intraspecific level.
Creationist Darwin predicted that macroevolution would be a continuous and gradual process. In contrast, microevolution refers to the origin of new species and taxonomic divisions above the species level, as well as the origin of complex adaptations such as the vertebrate eye.

Answer:
The illustration of anaphase stage of mitosis is where the spindle fibers start to pull away from the center of the cell.
MITOSIS:
Mitosis is the process whereby a single cell results in two daughter cells that are genetically identical to one another.
Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase.
Prophase: Condensation of chromatids to more visible X-shaped structure called chromosomes.
Metaphase: Chromosomes line up at the cell's equator
Anaphase: Chromosomes are pulled apart by the spindle fibers that attached to their centromere.
Telophase: Reformation of the nuclear membrane.
According to this question, in the anaphase stage, spindle fibers start to pull away from the center of the cell to separate the chromosomes.

A puddle of water that Kim observed on the way home from school had frozen by the next morning. what caused this change?
Answer: it froze due to the cold temp
Explanation: Freezing happens when the molecules of a liquid get so cold that they slow down enough to hook onto each other, forming a solid crystal. For pure water, this happens at 32 degrees Fahrenheit, and unlike most other solids, ice expands and is actually less dense than water. That is why ice cubes float!
