Answer:
Reading graphs: The variable plotted on the x-axis is year while the two variables plotted on y-axis are both wolves and moose.
Interpreting variables: The population of moose rose from 800 to 1550 between 1965-1972 while the population of wolves rose from 24 to 43 between 1973-1976.
inferring: The change in population of moose might cause a change in wolves population as a result of the feeding pattern of wolves, perhaps the contest between them was affected by availability of another prey which allows the predator (wolves) to feed on another prey, hence increasing the population of moose.
Conclusion: The dip in population of moose between 1974 and 1981 could be attributed to voracious feeding pattern the predator (wolves) had on the prey (moose) which inturns allows the dip in population during the above mentioned years.
Predicting: If there is a disease infection in wolves, then there would be an increase in the population of moose the next year as a result of disruption in the predator-prey contest, hence; allows one to be more populated the following year.
Explanation:
From the above assertions, it could be deduced that only when the feeding pattern of the predator (wolves) changes then the population of the prey would either be reduced or increased.
Answer: The invisible area around a magnetic object that can pull another magnetic object toward it or push another magnetic object away from it is called a magnetic field. It's kind of like those invisible “force fields” that surround an object with invisible power in sci-fi movies and books.
Explanation:
Answer: Cellular respiration is a process that traits place in the mitochondrion of a cell. it is a cells way of producing energy. it is needed because without it your body wouldn't be able to perform any actions that needed energy, eventually leading to death.
Answer:
○Two electrons in the outer shell and a full outer electron s shell
○Low electron affinities
○Low electronegativities
○Relatively low densities
○Relatively low melting points and boiling points, as far as metals are concerned
○Typically malleable and ductile. Relatively soft and strong.
The elements readily form divalent cations (such as Mg2+and Ca2+).
The alkaline earth metals are very reactive, although less so than the alkali metals. Because of their high reactivity, the alkaline earths are not found free in nature. However, all of these elements do occur naturally. They are common in a wide variety of compounds and minerals.
These elements are shiny and silver-white as pure metals, although they usually appear dull because they react with air to form surface oxide layers.
All the alkaline earths, except for beryllium, form corrosive alkaline hydroxides.
All of the alkaline earths react with halogens to form halides. The halides are ionic crystals, except for beryllium chloride, which is a covalent compound.
A cell must grow and the DNA must be copied so there is a full set of DNA to pass on to the daughter cells
