When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using
Answer:
Answer: process and facts, because they are using a systematic method to measure and then record data
Explanation:
During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.
When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using?
Answer: process and facts, because they are using a systematic method to measure and then record data
The parts of the scientific cycle are the scientists using process and facts, because they are using a systematic method to measure and then record data. The correct option is A.
What is scientific cycle?Simply put, when scientists discuss periods, they are referring to sequences of events that recur themselves. Some cycles are extremely simple.
Scientific theories are generally born and die as a result of what is known as the scientific process.
This is a general cycle in which a pattern in some phenomena is identified, a general hypothesis is formed, new phenomena are predicted based on this supposition, and the predictions are tested by experiment.
The research and development cycle is made up of five iterative activities: problem analysis, underpinning, design, integration, and evaluation.
Scientists use procedure and facts as part of the scientific cycle even though they use a systematic method to gather and then record data.
Thus, the correct option is A.

d. reproduction
Answer:
Explanation:
homeostasis
For a plant sunlight is an example of ; ( C ) homeostasis
Plants require the light to carryout photosynthesis for proper growth and production of its food therefore insufficient sunlight will affect the growth and development of a plant. also some plants grow towards a light source ( phototropism ). to maintain its internal system.
Since the sunlight is not found within the plant but it has a direct effect on the growth and development of the plant, it is an example of a homeostasis while reproduction takes place within the plants
Hence we can conclude that for a plant sunlight is an example of ; ( C ) homeostasis

i need to know which is the independent and dependent variable please help!!
Answer:
Calculator is independent, student is dependent, math problem is constant
Explanation:
The atmosphere is made up from 77 percent nitrogen (N2), 22 percent oxygen (02) and all other gases are less than one percent of the atmosphere. The crust, part of the Geosphere is made up for almost 47 percent of Oxygen. Why can’t we breathe the crust?
Answer:
Well, we can not breathe in solids. But I'm guessing that this question is more based on the type of oxygen that's in the crust.
There are oxygen ions in m=almost everything in the earths crust, yes, but we do not breathe in the same type of oxygen that is bound to their crystal structures.
There are plenty of oxygen atoms in the earth's crust, but there are very few oxygen molecules. The crust is primarily made up of silicate minerals…feldspars, pyroxenes, amphiboles, quartz, etc. There are also lots of oxide, carbonate, phosphate, and sulfate minerals. These all have large amounts of oxygen atoms tightly bound in their crystal structures. But this is not the free molecular oxygen that we breathe.
Because free oxygen molecules (O2) are very reactive, vanishingly little of it is found in the crust below the depths of shallow cool groundwater. Air, including its 20% oxygen, dissolves in rain as it falls from the sky. Some of this air-saturated water soaks into the earth and recharges the groundwater system, carrying the air with it. Nitrogen, argon, and other unreactive trace gases can be circulated quite deeply with this downflowing water…to 10km or more. However oxygen is very reactive, and so it reacts with the minerals in the rocks (or forms new minerals) before it gets transported very deep. You have probably seen evidence of this reaction in red or brown stained rocks exposed at the earth's surface that have been oxidized by downflowing surface waters.
In the geothermal industry, where wells produce deep, magmatically heated waters for power generation, we routinely see atmospheric nitrogen and argon in the produced fluids. This, along with the isotopic composition of the water, gives a clear indicator atmospheric origin of the water (most of it, at least). However there is absolutely no dissolved oxygen in those waters. It all reacted with the rock long ago.
I NEED THE ANSWER ASAP!!!!!!!! Wastewater is treated with chlorine to kill bacteria. However, chlorine can be toxic to certain fish that live in the ocean. Why does this most likely add to the cost of cleaning water?
Answer:
if they are dumping wastewater into the ocean your place isnt that smart now are they
the best thing to do is clean the water and use it for drinking water etc
cuz the fact that there is not alot of drinking water but we have to be carefull of how much water we turn into drinking water cuz if it all tuned into fress drinkable water the world would be so much lighter and the atmosphere would most likly not be able to support us or other lifeforms and if we did manage to live then we would need to become so much heaver so a normal person would go from 200 pounds to 500 or more easily so there are ristriction on how much we can turn into dinkable water but we have such less rn but it would be easy to calculate with the help of some math people

At the coordinates 45 degrees W & 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W & 45 degrees S? 8:32 AM, 10:32 AM, 11:32 AM, 7:32 AM
Answer:
The correct option is;
7:32 AM
Explanation:
The information given are;
The time at 45 degrees W and 72 degrees N = 9:32 AM
The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location
Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted
The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM
The latitude of a place left out in the calculation of the relative time of a place.

How can a female inherit red-green color blindness?(1 point) Her mother is a carrier, and her father has the condition. Her mother is not a carrier, and her father has the condition. Females cannot inherit red-green color blindness. Her mother is a carrier, and her father does not have the condition.
Answer:
The correct answer is - Her mother is a carrier, and her father has the condition.
Explanation:
Colorblindness is a sex linked recessive disease that is passed from the parent to the offspring through X chromosome that have recessive gene of the disease. It is rare in the females as the very low chances of the females to inherit two copies of disease gene allele. But as only one allele is present in males of X chromosome and if there is disease copy he will be color blind.
To get a colorblind female the girl child must get two copies of these allele that has recessive X chromosome one from her carrier mother and other from her conditioned father. Check image for punnet.
Thus, the correct answer is - Her mother is a carrier, and her father has the condition.
Why do astronomers depend on technology?
Answer:
The definition including its given subject is provided in the subsection below on clarification.
Explanation:
Slightly earlier astronomers didn't rely on technology-they only stayed up throughout the night in something like a profession and glanced up to take a track of what they would have seen. They require innovation if they wish to do it more than anything. Today scientists really would like to grasp extraordinarily distant or very small objects so they need many more technologies, such as analyzing frequencies that only the human eye couldn’t detect.Nuclei within the gray matter of the spinal cord that receive information from sensory receptors such as pain or pressure receptors in the skin are _____ nuclei.
