2. Explain the purpose of alternation of generations
Answer:
The alternation of generations allows for both the dynamic and volatile act of sexual reproduction and the steady and consistent act of asexual reproduction. When the sporophyte creates spores, the cells undergo meiosis, which allows the gametophyte generation to recombine the genetics present.

There's a block of metal with the dimensions below that weighs 2500 grams. What is the density of
the metal?
The correct answer is 37.72 g/[tex]cm^{3}[/tex]
Explanation:
To find the density of this block the first step is to find the total volume or space occupied by the block. This is because the volume is one of the factors that determines density (Density = mass ÷ volume). Now, to find the volume multiply the three sides given or the length, width, and heigh:
6 cm × 3 cm × 4 cm = 72 [tex]cm^{3}[/tex]
Finally, calculate the density:
2500 grams ÷ 72 cubic centimeters = 37.72 g/[tex]cm^{3}[/tex]
If less dense crust collides with less dense
crust, then this must be an example of
A. continental crust to continental crust collision..
B. continental crust to oceanic crust collision.
C, oceanic crust to oceanic crust collision.
D, a subduction zone.
The subduction zone is the area where a less dense plate collides with a denser plate, causing the subduction of this last one. The correct option is D. a subduction zone
What is a subduction zone?
The term subduction refers to the sinking process of one plate under another plate after a collision event.
Subduction zones are the areas in which plates approximate, collide, and one of them must subduct under the other one.
The plate that subduces is always the denser and older one. The less-dense plate superpose over the denser one and push it down toward the mantle. At this point, rocky material from the subductive plate melt again.
The correct option is D. a subduction zone.

Why is natural selection not considered a random event?
Answer:
Natural selection is not random because
Explanation:
Natural selection is not random because it is based on fitness in the context of environmental conditions. This, more often than not, implies logical choices based on given external parameters. For example, if the weather remained cold, selection would go to those who are fit in the cold not those who are fit in the hot weather.

What is found inside of ice core samples that scientists use to determine the composition of the atmosphere at the time the ice was formed?
A. Dust particles
B. Ions
C. Gas bubbles
D. microbes
A. and C.
Explanation:
Ice cores contain evidence of trace elements, gas bubbles, dust, pollen, even viruses and bacteria that can be traced back in time to yield vivid images of Earth's history and prehistory for those who learn to read them.
Gas bubbles are typically found inside ice core samples that scientists use to determine the composition of the atmosphere at the time the ice was formed. Thus, the correct option is C.
What is Atmosphere?An Atmosphere may be defined as a type of layer that significantly consists of numerous gases. It surrounds any celestial body like earth. The atmosphere of the earth is generally composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
During the time, when scientists formed the ice, gas bubbles of carbon dioxide, methane, and other greenhouse gases are significantly present inside the cores of the ice sample.
Apart from this, some sorts of bacteria, viruses, and other microorganisms are also visualized inside ice core samples.
In ancient times, the level of pollution is significantly low, so dust particles are not much highlighted in this region.
Therefore, gas bubbles are typically found inside ice core samples that scientists use to determine the composition of the atmosphere at the time the ice was formed. Thus, the correct option is C.
