Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answers
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.

Record the color and clarity of one of your mineral samples in Table 5 on the Exercise 2 Data Sheet. Remember, some minerals may have more than one color. 2. Determine the luster of your mineral, and record your observation in Table 5 on the Data Sheet. If you determine that the mineral has a nonmetallic luster, note whether it is earthyldull, pearly, silky, waxy, greasy, or vitreous. 3. Determine the streak color of your mineral by scraping it on the streak plate. Use only a small section of the streak plate, because you will be using it for each mineral. Record the streak color in Table 5 on the Data Sheet. Note: The streak test works only for minerals softer than the streak plate. If the mineral is harder than the streak plate, it will not leave behind any color. The streak plate has a hardness of about 6.5. 4. Test the hardness of your mineral by using the Mohs Hardness Scale (Table 2). Begin by trying to scratch the glass plate with the mineral. If the mineral scratches the glass, then the mineral is harder than 6.0. If it does not scratch the glass, keep going down the list of items on the Mohs Scale until you are able to scratch one of the items (or one of the items can scratch the mineral). Record your findings in Table 5 on the Data Sheet. Remember. If a mineral scratches an object, it is harder than the object. If the object scratches the mineral, it is harder than the mineral. 5. Determine the cleavage of your mineral. If the mineral has no planes of cleavage, then it fractures. You may need to use a hand lens to determine cleavageifracture. Refer back to Figure 7 in the lab section as a guide to help you identify cleavage planes. Record your observations in Table 5 on the Data Sheet. CeScience Labs, 2016 6. Record any other distinctive characteristics you encounter. For example: If you suspect a mineral is calcite, place a couple drops of acetic acid (with a pipette) onto the mineral surface and watch for effervescence. Evidence of effervescence would go in the column titled "Other Distinctive Properties" in Table 5. Note: If you choose to use the acetic acid, be sure to wear the gloves supplied in your safety kit. Acetic acid is not strong enough to cause damage to your home or the environment, but it can irritate skin. The acetic acid can be rinsed off the mineral in the sink. 7. Repeat Steps 1-6 for the rest of the mineral samples. 8. After you have tested all of the minerals and recorded your observations, compare your findings to the minerals and properties listed in Table 4 to identify the unknown minerals. List the names of each mineral in the last column of Table 5. 9. Use your findings to answer the Post-Lab questions. Table 5. Mineral Identification
Answers
The color, clarity, luster, streak color, hardness, cleavage, distinctive characteristics, and mineral identification should be recorded in Table 5 on the Data Sheet.
When conducting a mineral analysis, it is important to record various properties to accurately identify the minerals. In Step 1, we record the color and clarity of the mineral sample. It's worth noting that some minerals may exhibit more than one color. The color refers to the outward appearance of the mineral, while the clarity pertains to the presence or absence of impurities or inclusions within the mineral.
we determine the luster of the mineral. Luster refers to the way light reflects off the surface of the mineral. It helps categorize minerals as metallic or nonmetallic. If the mineral has a nonmetallic luster, we further specify whether it appears earthy, dull, pearly, silky, waxy, greasy, or vitreous.
involves determining the streak color of the mineral. This is done by scraping the mineral against a streak plate. The color of the streak left behind can be different from the mineral's outward color. However, it's important to note that this test is effective only for minerals softer than the streak plate, which has a hardness of approximately 6.5.
we test the hardness of the mineral using the Mohs Hardness Scale. We try to scratch the mineral against a glass plate. If the mineral scratches the glass, it indicates a hardness greater than 6.0. If it doesn't scratch the glass, we continue down the scale until we find an item that can scratch the mineral or vice versa. The hardness test helps determine the relative hardness of the mineral compared to known substances.
involves examining the cleavage of the mineral. Cleavage refers to the tendency of a mineral to break along flat, parallel planes. If the mineral lacks cleavage planes, it fractures instead. A hand lens may be required to identify cleavage or fracture characteristics accurately.
we record any other distinctive characteristics encountered during the analysis. This could include performing additional tests or observing specific properties unique to certain minerals.
Finally, in Step 8, we compare our findings from Steps 1-7 with the minerals and properties listed in Table 4 to identify the unknown minerals. The names of each identified mineral are then listed in the last column of Table 5.

________is the terms used for a bundle of axons in the central nervous system (CNS) and a ______ is the term used for axon bundles in the peripheral nervous system (PNS)Cerebral spinal fluid; plasmaGanglion; lobeTract; nerve
Answers
In the central nervous system (CNS), a bundle of axons is referred to as a "tract," while in the peripheral nervous system (PNS), axon bundles are called "nerves."
The central nervous system (CNS) and peripheral nervous system (PNS) are two major divisions of the nervous system. In the CNS, which includes the brain and spinal cord, a bundle of axons is called a "tract." Tracts are organized pathways that transmit information between different regions of the CNS.
These axon bundles are typically named based on their origin and destination, as well as their specific function.
In contrast, in the PNS, which consists of nerves outside the CNS, axon bundles are referred to as "nerves." Nerves are composed of bundles of axons along with their associated connective tissues, blood vessels, and supportive cells.
They serve as communication pathways between the CNS and various parts of the body, relaying sensory information from sensory receptors to the CNS and transmitting motor commands from the CNS to muscles and glands.
The distinction between tracts and nerves lies in their location within the nervous system. Tracts are found within the CNS, while nerves are present in the PNS, extending from the CNS to different body regions.

Control of respiration is based on input from mechanoreceptors that monitor ______ and chemoreceptors that monitor ______.
Answers
Control of respiration is based on input from mechanoreceptors that monitor lung inflation and chemoreceptors that monitor blood O2, CO2, and pH.
Chemoreceptor feedback is one method used to regulate breathing. The brain's central chemoreceptors, which react to changes in the partial pressure of carbon dioxide in their immediate environment, and arterial chemoreceptors, which monitor and react to changes in the partial pressure of oxygen and carbon dioxide in the arterial blood, are two different types of respiratory chemoreceptors. Ventilation levels act as though they were controlled to keep the arterial blood adequately oxygenated and to maintain a consistent level of carbon dioxide partial pressure. Both the rate and depth of breathing rise when chemoreceptor activity is increased due to hypoxia or an increase in carbon dioxide partial pressure, which returns oxygen and carbon dioxide partial pressures to their normal levels.On the other hand, excessive ventilation lowers the partial pressure of carbon dioxide, which reduces the activity of chemoreceptors and decreases ventilation.learn more about chemoreceptors here; https://brainly.com/question/12061102

describe the relationship between the total number of mutant alleles in an individual and the concentration of cysteine in the urine.
Answers
There is no clear relationship between the total number of mutant alleles in an individual and the concentration of cysteine in the urine. While mutations in certain genes can lead to disorders that affect cysteine metabolism and excretion, the number of mutant alleles alone does not necessarily indicate the severity of the condition or the resulting concentration of cysteine in the urine.
Other factors, such as dietary intake and overall health, can also influence cysteine levels in the urine. Therefore, it is important to consider multiple factors when evaluating cysteine levels in an individual.The total number of mutant alleles in an individual refers to the number of altered copies of a gene that an individual possesses. These mutant alleles can lead to abnormal production or function of the gene's product, which in this case is an enzyme responsible for the metabolism of the amino acid cysteine. When an individual has one or more mutant alleles that affect the metabolism of cysteine, it can result in a reducedability to break down cysteine properly. This, in turn, can lead to an increased concentration of cysteine in the urine.
In summary, the relationship between the total number of mutant alleles in an individual and the concentration of cysteine in the urine can be described as a direct relationship, where an increase in the number of mutant alleles may lead to an increase in cysteine concentration in the urine. This is because the presence of mutant alleles can affect the proper metabolism of cysteine, leading to its accumulation and excretion in the urine.
