What conditions on the Moon's surface do
you think engineers had to consider when they
designed the lunar rover?
Help pls. Explain
Answer:
The differences in gravity, craters on the moon and unknown materials.
Explanation:
These would all be helpful to consider.
The rover would have to be light enough to launch with the Apollo payload as it was, but also be sturdy enough to traverse all types of terrains, conquer slopes up to 25 degrees, and function in temperatures ranging from -279 to 243 degrees Fahrenheit
Note that air suspension, which is in most cars, wont work, since theres no air. They need to automate a way to land the rover without breaking it to also. It also needs to survive long enough.

tại sao lại có sấm sét
Khi hai đám mây tích điện trái dấu lại gần nhau, hiệu điện thế giữa chúng có thể lên tới hàng triệu vôn. Giữa hai đám mây có hiện tượng phóng tia lửa điện và ta trông thấy một tia chớp. Vài giây sau ta mới nghe thấy tiếng nổ, đó là sấm (do vận tốc ánh sáng nhanh hơn vận tốc của tiếng động nên ta trông thấy tia chớp trước). Khi đám mây dông tích điện đi gần mặt đất tới những khu vực trống trải, gặp một vật có độ cao như cây cối, người cầm cuốc xẻng… thì sẽ có hiện tượng phóng tia lửa điện giữa đám mây và mặt đất. Đó là hiện tượng sấm sét.
what are the causes of cancer????
Answer:
Explanation:
Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide
Two haploid daughter cells are produced during what phase
Answer:
The phase in which two haploid daughter cells are produced is telophase.
Explanation:
What could happen if the wrong organism is identified as the cause of disease?
If the wrong organism is identified, then people would probably be in danger. Because you wouldn't know if the actual species is deadly or not. Lets say that the wrongly identified organism isn't deadly, but the real one is. Everyone is just strolling along, and then you're dead because it bit you.
And of course, if you're coming up with a cure, (because both are toxic) you're making the wrong one. Which could harm people just based off their bodies and what you're putting into them. Everyone is different.
Cancer cells do not respond to signals
that regulate what process?
A. transcription
B. cell cycle
c. metabolism
Answer: Cell cycle, B
Cancer cells do not respond to the signals that regulate the process of cell cycle. The correct option is B.
What signals do cancer cells respond?Cancer cells do not respond to signals that regulate the cell cycle. The cell cycle is the process by which cells grow, divide, and create new cells. Normally, cells are tightly regulated by signals that tell them when to start and stop the cell cycle.
However, cancer cells have mutations that allow them to ignore these signals and continue dividing uncontrollably. This leads to the formation of tumors and the spread of cancer throughout the body.
Cancer cells often ignore signals that regulate the cell cycle, leading to uncontrolled growth and division, which ultimately contributes to the formation of tumors.
Therefore, the correct option is B.

Select ALL of the molecules that are
produced in cellular respiration and are reactants in photosynthesis.
Answer:
6Carbon Dioxide (CO2) + 6Water (H2O) + energy
Explanation:
The products for cellular respiration are the same as the reactants in photosynthesis. Each process is dependent upon the other. The results/products of cellular respiration are 6 carbon dioxide molecules and 6 water molecules along with the releasing of energy. In photosynthesis energy is absorbed in cellular respiration energy is a byproduct.

What is one advantage of sexual reproduction?
A. offspring show more genetic variation
B. offspring are identical to parents
C. offspring need only one parent
D. more offspring are born
Answer:
B
Explanation:
Organisms produced by sexual reproduction have two parents and are genetically similar to both but not identical to either. it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.
Create an argument to help inform your community about the impacts of sprawl on wetland ecosystems and ways to protect wetlands from further decline. Use evidence and scientific reasoning to support your response.
Answer:
Negative impact.
Explanation:
There is a negative impacts of sprawl on wetland ecosystems because it destroys the habitat of thousands of organisms. Making laws to restrict housing in a wetlands and avoiding making houses on the wetland are the ways to protect wetlands from further decline. Human activities is the main factor that causes harm to wetland ecosystem so sprawl has adverse impact on wetland ecosystem.

Samuel has a block of modeling clay, three heavy blocks, and a hot plate covered by a tray as shown. How could he use these items to model the process of an existing rock becoming a metamorphic rock, according to the rock cycle, and to model the flow of energy that drives this process?
Answer:
Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray.
Explanation:
Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray is used for forming a metamorphic rock. Metamorphic rocks are formed when the rocks are placed to high heat, high pressure, hot mineral-rich fluids or combination of all these three factors. Conditions like these are found deep within the Earth so by placing block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray formed metamorphic rock.

If the parent has 8 chromosomes
and reproduces asexually, how
many chromosomes will the
offspring have?
A. 4
B. 8
C. 16
Answer:
B. 8 chromosomes
Explanation:
If the parent has 8 chromosomes and reproduces asexually, then the offspring will also have 8 chromosomes.
The reason is that the offsprings will be the exact clones of their parents, in asexual reproduction.
The offsprings also have the exact and same number of chromosomes of their parents. So, option (B) is the answer.
B.8
They will have the same chromosomes, and will also have the exact same chromosome number that the parent had.
So, in this situation, the offspring will also have 8 chromosomes.

resources within communities. Compared to other communities, which of these locally
available resources is most likely to be depleted in desert communities?
A. Mineral
B. Oxygen
C. Gasoline
D. Water
Answer:water
Explanation:
In comparison with other communities, the locally available resource which is most likely to be depleted in desert communities is: D. water.
What is a desert?A desert can be defined as an extremely dry area of land that is characterized by sparse vegetation, especially due to very low rainfall and precipitation.
Generally, the amount of water available for plants and other living organisms in all deserts is usually very little (low).
In conclusion, we can infer and logically deduce that water is the locally available resource which is most likely to be depleted in desert communities.

A team of researchers is studying the distance between ribosomes attached to the rough ER in a type of cancer cell. The researchers are writing a grant to provide support for a microscope to use to study this. They need to purchase a microscope with a very high magnification to observe the distance between individual ribosomes in a cross section of a cancer cell. Based on the information given, what type of microscope would you suggest
Answer:
The correct answer is - Electron microscope.
Explanation:
The electron microscope is one microscope among all other types of microscope that has the ability to get high magnification and resolution levels, That helps in look and study things right down to each individual atom.
The light microscope is not able to show direct structures of the cell components such as cell membrane, ribosomes, ER, and other organelles. To see them we need to achieve the high magnification power that is provided by an electron microscope.
