How can you distinguish the dorsal and ventral sides of an earthworm?
Answer:
Yes
Explanation:
The earthworm has a rounded dorsal (back) surface and a flatter ventral (belly) surface. Usually the dorsal surface is darker than the ventral surface (though sometimes this is obscured in the preservation process).
Answer:
The ventral side is lighter than the dorsal side and more pale and kind of flattened unlike the dorsal side which is darker and round.

please help Mark and Vikki live in two different areas of North America. The temperature in Mark’s town today is 30°F. The temperature in Vikki’s town is 82°F. In both towns, the relative humidity is 90%. Is the amount of water vapor in the air the same in Mark’s and Vikki’s towns? Explain your answer.
Answer:
I think that the amount of water vapor in the air will be different because in Mark's town, it is cold and water in the clouds might turn to ice and come down as snow. And in Vikki's town, it is very warm so the water vapor might come down as rain.
I hope this helped! I was in a rush but I'm positive that this is correct.
Which component of the earth’s atmosphere is decreased due to photosynthesis?
ozone
oxygen
hydrogen peroxide
carbon dioxide
Answer:
Carbon Dioxide
Explanation:
Let's see the reaction of Photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Where carbon dioxide and water are reactants and glucose and oxygen are products which means CO₂ and H₂O are taken from the environment and glucose is supplied to plants while oxygen is supplied back to the environment.
What is the most environmentally friendly form of building?
A. Concrete
B. Brick
C. Steel
D. Timber
Answer:
D) Timber
Explanation:
Concrete creates a large carbon footprint as carbon dioxide is released during its production. Steel releases air emision like CO, SOx, NOx, PM2. Whereas, brick is made out of clay the heat required for manufacture is usually gained from coal burning releasing emissions into the atmosphere. Although timber contributes to deforestation when managed sustainably has the potential to be carbon neutral/sustainable.

In the United States, the moon’s pull is strongest during which season?
1. spring
2. summer
3. fall
4. winter
Explanation:
Gravitational pull is affected by mass and distance. Since the moon’s mass does not change, the moon’s distance between Earth and the moon is the main consideration for the strength of lunar gravity. The moon’s pull on Earth waxes and wanes as the moon follows its elliptical orbit around the Earth, the distance between the two celestial objects increases and decreases. When they are nearest to each other, the moon is in the point of its orbit called the perigee, and its pull on Earth is the strongest.
On Earth, the moon’s gravity primarily is manifested as high and low tides, as the water bulges toward the moon. The effects of lunar gravity are felt the most at the constantly changing spot on Earth that is directly beneath the moon, called the sub-lunar point. At most times of the year, the moon has a greater pull on Earth than the sun does, but this changes during the times of year when the Earth’s orbit brings it closer to the sun. At these times, the sun’s gravitational pull causes spring tides, and when these coincide with the moon’s orbital perigee around the Earth, they are called perigean spring tides.
Earth exerts a gravitational pull on the moon 80 times stronger than the moon’s pull on the Earth. Over a very long time, the moon’s rotations created fiction with the Earth’s tugging back, until the moon’s orbit and rotational locked with Earth. This is called "tidal locking," and it explains why the same side of the moon always faces the Earth.
Answer: The correct answer is 1. spring

During daylight savings, Christie's neighborhood soccer games get cut short because the sky becomes dark much earlier than during the summer. Her father talked to the electric company about installing large lights above the field so Christie and other kids in the community could continue their soccer games after dark. The electric company informed Christie's father that although the light poles could be installed, there are too many short trees and trees with low branches in the park to connect electrical lines. Without electricity delivered to the light poles, they would not work. Christie and her father talked about this information with neighborhood residents and together they came up with several ways to solve the problem.
Considering the concerns of everyone involved, which idea would be the BEST solution to the problem?
A)
Instead of electrical light poles, install solar-powered light poles.
B)
Parents can leave their cars running with headlights on facing the park.
Build several large fire pits around the field and light them each night.
D)
Cut down the larger trees, install the electrical lines, and replant the area
with shrubs.

How does energy affect competition in a rainforest?
Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.

3. (4pts) A constraint is a limitation or condition that must be satisfied by a design. For example, you may onl
be able to use certain materials, or you might want the device to operate at a certain speed.
What was a constraint (a limitation or a condition) in this version?
Answer:
As seen in the question above, "constraint" is a word that indicates a limitation or condition. In this case, we can say that the "restriction" is an imposition to a limit under a given situation, and it can also mean an imposition of the free execution of an activity, skill and even limitation and a conditioning factor to a certain freedom.

Your answer is CLEAR CUTTING...
Explanation:
Clear cutting is when people/ industries harvest and regenerate trees areas in which all trees are cleared from a site completely...
HOPE THIS HELPS!!
Clear cutting can cause secondary succession. So, the correct option is A.
What is Secondary succession?When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including fire, flooding, high winds, and human activities (such as logging of forests).
After the primary succession has indeed been disrupted as well as some animals and plants are still there, the secondary succession occurs. For the reasons listed below, the secondary succession is typically quicker than the primary succession.
There is already earth in place.The soil may still contain seeds, roots, and subsurface vegetative organs.Therefore, the correct option is A.

It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.
What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.
