Between 3 o'clock and 11 o’clock
Explanation:
Ms. Huskey asked her science class to develop a scale model of the solar system where the sun has a diameter of 1.0 m given that the sun has a diameter of 1,392,000 km. How large should Shannon make the smallest planet in his scale model of the solar system?
Answer:
3.5 mm
Explanation:
Given the size of the sun, the scale ratio is :
[tex]\dfrac{1m}{1,392,000km}[/tex]
Now to determine how large the smallest planet should be, you just need to make sure that its measurement is proportion to that scale. According to your table, the smallest planet is Mercury with a diameter of 4,879.4 km. Now we can write a proportion for this, to determine the scale:
[tex]\dfrac{1m}{1,392,000km}=\dfrac{x}{4,879.4km}[/tex]
Cross multiply then divide to solve for x.
[tex]\dfrac{1m\times 4,879.4}{1,392,000km}=x\\\\\dfrac{4,879.4m}{1,392,000}=x\\\\0.00350m=x[/tex]
So the smallest planet would be 0.0035m. Since your choices are in mm (and that is a very small number to estimate) we can convert it into mm.
1 meter = 1,000 millimeters
[tex]0.0035m\times\dfrac{1,000mm}{1m}=3.5mm[/tex]
The answer is then 3.5mm.
To maintain the scale proportion, if the sun is 1m in diameter in the model, Shannon should make the smallest planet, Mercury, 3.5 mm in diameter.
Explanation:The smallest planet in our solar system is Mercury, which has a real diameter of approximately 4,879 km. Given that the Sun's real diameter is 1,392,000 km, to find out how large Shannon should make Mercury in his scale model of the solar system, we have to keep the proportions the same.
To achieve this, we need to set up a proportion using real-life sizes and scale sizes. In this case, the proportion would be (4,879 km / 1,392,000 km = x / 1 m), with 'x' being the diameter of Mercury in the model. Solving for 'x', we get x = (4,879 km / 1,392,000 km) * 1 m, which equals approximately 0.0035 m, or 3.5 mm. Therefore, in Shannon's model, if the Sun is 1m in diameter, the smallest planet, Mercury, should be 3.5 mm in diameter.

Explanation:
if there are 300 worms in 100m2 of lawn , what is there population density
Answer:
3 worms per square meter
Explanation:
In order to get to the population density of the worms, we need to take a basic measurement for it. Since we have a land area in square meters, we will take the square meter as a basic unit. On the land of 100 square meters, we have 300 worms. In order to get to the result we need to use the simple formula for population density:
population density = population / land area
300 / 100 = 3
So we have a result of 3, thus meaning that the population density of the worms is 3 worms per square meter.

how do organisms grow
Hello! My name is Zalgo and I am here to help you out on this amazing day. Organisms grow, but only certain organisms are capable of growing. The meaning of growing is "to get bigger/expand" and the way that multicellular cells grow is by making more cells. Plants also have special tissues called "Meristems" where the growing process happens. Single celled organisms (unicellular organisms) increase their numbers by "dividing" and making more cells like themselves.
I hope that this helps! :3

one way meiosis I is different from mitosis is that
a. meiosis I produce 2 haploid daughter cells, but mitosis produces 2 diploid daughter cell
b. sister chromatids are pulled apart during meiosis I, but not during mitosis
c. replication occurs during interphase before mitosis, but not before meiosis I
d homologous chromosomes are segregated during mitosis, but remain together during meiosis I.
Answer:c
Explanation:
Final answer:
Meiosis I differs from mitosis in that it produces two haploid cells with genetic variation due to homologous chromosome pairing and crossover, whereas mitosis produces two genetically identical diploid cells without these features.
Explanation:
One way meiosis I is different from mitosis is that meiosis I produce 2 haploid daughter cells, while mitosis produces 2 diploid daughter cells. This is because meiosis involves two rounds of nuclear division, resulting in cells with half the number of chromosomes as the parent cell. In contrast, mitosis is a single division that results in daughter cells that are genetically identical to the parent cell. Additionally, in meiosis I, homologous chromosomes are paired and crossover occurs, which is not seen in mitosis.
During meiosis I, synaptonemal complex binds homologous chromosomes. Chiasmata form, allowing crossover between nonsister chromatids, resulting in genetic variation in the daughter cells. These chromosomes line up as tetrads on the metaphase plate, with spindle fibers attached to kinetochores of homologous chromosomes, a process unique to meiosis I. Meanwhile, mitosis does not feature these events and maintains the diploid state without genetic recombination.

Hello Midoria, thank you for asking a question here on Brainly!
You Asked ➤ What is the approximate relative humidity in the situation shown below?
↴ OUR CHOICES ↴
A: 9%
B: 21%
C: 30%
D: 44%
------------------------------------------------------------------------------------
Answer ➤ D: 44%
Explanation: To solve this problem, we need to know the formula on receiving the wet bulb depression shown on the thermometers. While looking at this image, I can see there is a dry bulb and a wet bulb. We know that dry bulb is 29.8 degrees and that the wet bulb is 20.9 degrees. If we find the difference, we will solve for the depression.
➤ 29.8 - 20.9
➤ = 8.9 degrees Celsius
The next step is to look at the psychrometric table you have by the timer and thermometer and figure out what the approximate relative humidity is by looking for the row that matches the dry bulb and wet depression temperature to the nearest value.
➤ The nearest value to 29.8 degrees (the dry bulb) is 30 degrees.
➤ The nearest value to 8.9 degrees is 9 degrees.
Find which value intersects with the row and column of the table. We can see that the value intersect at 44 percent from the row and column of the graph. That is our final approximate relative humidity.

Describe the term Continental Drift and seafloor spreading.
Continental drift is the theory that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Answer:
Continental Drift-was a theory that explained how continents shift position
on Earth's surface.
Seafloor Spreading-helps explain continental drift in the theory of PLATE TECTONICS. when oceanic plates diverge, tensional plates causes fracture to occur in the lithosphere.
The location of the water table is subject to change.
Please select the best answer from the choices provided
OT
OF
Answer:
The location of the water table is subject to change.- True ( first choice)
The water table, which is not fixed, can change location based on several factors. These factors include precipitation amounts, human water usage, and environmental changes. This changing location of the water table is pertinent to hydrology, water management, and environmental conservation.
Explanation:Yes, the location of the water table is indeed subject to change. This is due to the fact that the water table isn't fixed, but varies in response to several factors. These include rainfall, the amount of water used by people, and changes in the environment. For example, during periods of heavy rain, the water table may rise as more water soaks into the ground. Conversely, during times of drought, or when humans extract large quantities of groundwater, the water table may fall. This variability of the water table location is an important aspect to consider in fields such as hydrology, water management, and environmental conservation.

i took this quiz awhile back
When a plant dies, most of the nitrogen in the plant's tissues is:
Upon plant death, nitrogen is reverted back to ammonium ions through ammonification, which is later transformed into nitrate, a plant-usable form.
When a plant dies, most of the nitrogen in the plant's tissues is released back into the environment in the form of ammonium ions (NH4-). This process is known as ammonification, carried out by decomposers breaking down the organic compounds of the dead plant. Eventually, the ammonium ions can be converted by soil bacteria into nitrate (NO3-), which is a form other plants can readily use.
