B. Old individuals outnumber juveniles in the population as it grows.
C. The resources available are fully used by the population as it grows.
D. Natural selection changes the gene pool of the population as it grows.
Answer:
The right answe is C.
Explanation:
The limit to how large any given population could be is defined by the concept of " carrying capacity". It refers to the fact that in nature populations grow much faster than resources do, and this impose a limit to population sizes (if there is no enough nutrition sources, the number of individual can not go up).
Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results.

Rodrigo wants to find more ways to improve his latest design. Which of the following should he try?
(CHOOSE ALL THAT APPLY)
A - a more concentrated solution
B - a less concentrated solution
C - better insulation
D - less insulation
E - a greater amount of solution
F - a lesser amount of solution
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option are option C,E that is better insulation and a greater amount of solution.
Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
To improve his latest design Rodrigo should use a better insulation and a greater amount of solution.
Therefore, the correct option are option C,E.

The right answer is Slime molds are able to move
Mucilaginous mold are characterized because at some stage of their life cycle they form multinucleated aggregates (plasmodia) or multicellular (pseudoplasmodiums) that slide along the ground feeding on decaying plant matter. A few are parasites. They can be found on the ground, on the lawn and in deciduous forests. They are also common in leaf mulch or even in silt that accumulates in gutters. Some are aquatic, freshwater or marine.
The "body" of these Myxomycete consists of a mass of cytoplasm called plasmodium which is surrounded only by a thin membrane; there is no rigid wall like most mushrooms. This is why the plasmode can move by creeping or flowing, that is to say, by amoeboid movements.
B.Microclimate
C.Macroclimate
B. Natural selection explains how certain life forms are able to survive and reproduce after changes in their environmental conditions.
C. Natural selection comes from the collection of fossil record data that shows how life forms.
