Answer:
Annelids are segmented worms whereas roundworms are not segmented. Further, annelids have a true coelom while roundworms have a pseudocoelom. This means annelids have a well-developed mesoderm while roundworms lack a mesoderm.
What is a front?
-Air Masses and Fronts 9th grade science-
HELP ASAP
A air front is typically a transition zone between two unique temperature/humidity. Usually, one front would push the other away (typically if summer is hot, then the warm front will push away the cold, and for the winter, if it's cold, it's the opposite).
A stationary front, on the other hand, is when there is no change in the over all temperature for the region(s), and a occluded front is when the fronts mix, where it is followed by rain and a equillibrium of the temperature, whether to a warmer or cooler overall temperature.

Which part of these is a part of feedback loop that results in a cooling effect on the earth
Answer:
The answer is b: part of a feedback loop that results in a cooling effect on Earth
Explanation:
More evaporation of water due to warmer temperatures from various sources such as seas and oceans and even melting of glaciers cause low and thick clouds to form. These thick low clouds later result in rain. In addition, the rain causes the earth’s temperature to cool down.

Space travel has come a long way since Laika, but there are still many celestial bodies waiting to be explored. What do you think will be the biggest space mission of the twenty-first century? What challenges do you anticipate that the humans or space probes will experience on this journey? What specific accommodations or technological advancements will be needed to make the mission successful?
Answer:
NASA's Artemis program has a goal of landing humans on the moon in 2025 to begin building a base camp. This long-term human presence on the lunar surface will help NASA prepare for human space exploration missions of greater distance and duration, including an eventual crewed flight to Mars. Space can help us prepare the feutre Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras.
Explanation:
There hope it helps Also you could've done a little bit of resheerch skimmed a cupple sights to get an idea on what to wright about then go from there its just an idea thoe
We have learned more about gravity, the magnetosphere, the atmosphere, fluid dynamics, and the geological evolution of other planets, for instance, through studying the solar system. This sparked the creation of numerous technologies that benefit the economy and enhance life on Earth.
What specific accommodations, technological space travel?In 2025, astronauts will be sent to the moon as part of NASA's Artemis mission to begin creating a base camp. This prolonged human presence on the moon's surface will help NASA get ready for longer-duration human space flight missions, such a possible crewed trip to Mars.
Additionally, you could have done some research by scanning a few websites to get an idea of what to write about before moving on from there.
Therefore, We wouldn't have GPS, precise weather forecasting, solar cells, or ultraviolet filters in eyeglasses and cameras without space missions. We can prepare the feutre by using space. We can use space travel to support or refute scientific hypotheses that were formed on Earth.

If an object leaves Earth's gravitational field and floats in space, which one of the following will change?
A. The object's mass.
B. The object's weight.
C. Neither the mass nor the weight of the object will change.
D. Both the object's mass and weight.
Answer: B. The object's weight
Explanation:
Weight depends on gravity and is a measure of how much force gravity exerts on an object. Mass is the measure of how much matter is in an object and doesn't depend on gravity. In space, mass doesn't change but weight does.

2.）Hasani is a farmer. He uses a weed killer to control the weed population growth on his farm. Weed killers can stop the transportation of certain minerals in plants through the hair root tissue. Explain why.
How to answer this 2 question. Thanks
Answer:
1) sap is mostly sugar, so an aphid must consume a lot of sap to meet its nutritional requirement for protein.
Insects tend to be most active in the early morning that's why aphids are mostly found in the daytime
2) These herbicides interrupt cell division, which stops root growth in seedling weeds. Plants die because they cannot take up enough water and nutrients to sustain growth.

City water management is analyzing water samples from the local river for water pollutants that could be toxic to humans if found in drinking water. Their collection data is below.
Samples

12 mg/L
0.06 mg/L
2
One mile downriver from drinking water uptake facility
9 mg/L

One mile upriver from drinking water uptake facility
8 mg/L
0.04 mg/L
4

10 mg/L
0.05 mg/L
Toxic levels reached when nitrates are greater or equal to 10 mg/L and/or carbamates are greater or equal to 0.04 mg/L.
Which sample location(s)have nitrates or carbamates at toxic levels that could be collected by the water uptake facility?
Samples 1, 2, 4
Samples 1 and 4
Samples 3 and 4
Only sample 4
Aquatic toxicity is found in the four sample sites. But since the water uptake facility collects water from upriver, the correct option is C. Samples 3 and 4.
What is aquatic toxicity?Aquatic toxicity is the property of a substance to causes harmful effects on aquatic or water-dependent organisms.
Aquatic toxicity can be either,
Sharp ⇒ nocive effects after a short exposition periodCronic ⇒ nocive effects after a long exposition periodAquatic toxicity depends on the substance type and its concentration in water.
--
According to the problem statement, toxic levels are reached when
nitrates are greater or equal to 10 mg/Land/or
carbamates are greater or equal to 0.04 mg/L.Sample 1 ⇒ Two miles downriver from drinking water uptake facility
Nitrate → 12 mg/L ⇒ > 10 mg/L ⇒ toxic Carbamate → 0.06 mg/L ⇒ > 0.04 mg/L ⇒ toxicSample 2 ⇒ One mile downriver from drinking water uptake facility
Nitrate → 9 mg/L ⇒ < 10 mg/L ⇒ not toxic Carbamate → 2 mg/L ⇒ > 0.04 mg/L ⇒ toxicSample 3 ⇒ One mile upriver from drinking water uptake facility
Nitrate → 8 mg/L ⇒ < 10 mg/L ⇒ not toxic Carbamate → 0.04 mg/L ⇒ = 0.04 mg/L ⇒ toxicSample 4 ⇒ Two miles upriver from drinking water uptake facility
Nitrate → 10 mg/L ⇒ = 10 mg/L ⇒ toxicCarbamate → 0.05 mg/L ⇒ > 0.04 mg/L ⇒ toxicThe four sample sites have toxic levels. Both of the substances concentrations or at least one of them reaches the toxic level at each site.
However, since water uptake facility can colect water from upriver, we only need to consider these sample sites.
The correct option is C. Samples 3 and 4.
