which abiotic factor starts the phosphorus cycle?
Answer:
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water.
Which of these is FALSE?
a
Cells use ATP for cell work
b
Breaking down glucose gives off energy
c
Breaking down ATP gives off energy
d
1 ATP has more energy than 1 glucose
Answer:
D is false
Explanation:
D is false because after breaking down 1 glucose, around 36-38 ATP will be produced from ADP
A is true because cells use ATP for work
B is true, as breaking glucose makes ATP, which is just stored energy
C is true too, since ATP is an ADP connected to a phosphate. This bond contains energy and detaching the phosphate will power parts of the cell, for instance active transport systems.
heat moves through the atmosphere through the process of ?
Answer:
Heat moves through the atmosphere through the process of Conduction.
Explanation:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface.

What are some ways that the biosphere interacts with the other three systems?
Answer:
Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants.
Explanation:
Answer :Full Answer. A classic example of an interaction between spheres is when a plant (part of the biosphere), takes carbon dioxide from the atmosphere and water (the hydrosphere) through its roots from underground (geosphere) to perform photosynthesis, which provides the plant with food and releases oxygen into the atmosphere.

Why the body needs more water after exercising/performing rigorous activity
Answer:
Sweat and dehydration. When you exercise, your body sweats as it tries to return to its optimal temperature. As sweat evaporates from your skin, it removes heat from the body, but you also lose body fluid. So, you need to drink fluid during exercise to replace the fluids you lose when you sweat.
Fluids keep your body hydrated; without them your body won’t function at its best.
If you don’t drink enough fluid:
Your body temperature and heart rate may rise. That’s because when the total amount of water in your body is below normal level (hypohydration) your body can’t properly regulate heat. You may feel more fatigued than usual. You may not be able to think clearly – your motor control, decision-making abilities and concentration may be impaired. Your body’s functions may slow down – this includes gastric emptying, so you may feel uncomfortable in your stomach. Your performance in sport or exercise may not be as good as it could be. The impact is even worse when you’re active and dehydrated in hot conditions.What hydration means :The amount of water you need depends on a range of factors, such as climatic conditions, your health, your clothing, your exercise intensity and duration. So, being well hydrated will differ per person and situation.
As a guide, you probably need more fluid if:
you sweat heavily you have certain medical conditions, such as diabetes or heart disease you have cystic fibrosis, which means you have a high concentration of sodium in your sweat you are using a medication that can act as a diuretic, causing your body to lose more fluid you have a bigger body size you are fit (because fitter people tend to sweat more and earlier in their exercise) you are doing vigorous exercise you are active in hot or humid conditions.
Thirst isn’t the best indicator that you need to drink. In fact, if you feel thirsty, you are probably already dehydrated.
A good test of dehydration is the colour of your urine. If it’s pale and clear it means you’re well hydrated. The darker it is, the more fluid you need to drink.
Another sign of dehydration is a lack of sweat during vigorous activity, when you expect to sweat. No sweating is a sign that you’re both dehydrated and probably suffering heat exhaustion.
What dehydration means :
Dehydration occurs when your body’s water content is too low. Here are some body signals that indicate you haven’t had enough fluid:
headaches fatigue mood changes slow reaction times dry nasal passages dry or cracked lips dark coloured urine muscle cramps weakness confusion hallucinations.If you experience any of these symptoms, you may need to increase your fluid intake.
If you don’t rehydrate, your physical and mental performance is likely to be affected. A loss of fluid equal to two per cent of body mass (for example a 1.4 kg loss in a 70 kg person) is enough to cause a detectable decrease in performance. A loss of fluid equal to more than two per cent means you risk nausea, vomiting, diarrhoea and other gastro-intestinal problems.
It’s not possible to train your body to handle dehydration, so don’t delay fluid replacement to ‘get used to dehydration’. When you need water, you need it.
Sweat and dehydration
When you exercise, your body sweats as it tries to return to its optimal temperature. As sweat evaporates from your skin, it removes heat from the body, but you also lose body fluid.
So, you need to drink fluid during exercise to replace the fluids you lose when you sweat. That way, you’ll reduce the risk of heat stress, maintain normal body function, and maintain performance levels. The general rule is: if you’re sweating, you need to be drinking fluids.
Over-hydration, in rare but severe cases, can lead to death. To avoid this, it can be useful to know your sweat rate. That way, you can work out exactly how much you should be drinking. Or, talk to your GP or an accredited sports dietitian for a fluids plan.
To work out your sweat rate:
Empty your bladder. Weigh yourself in minimal clothing, as close to the start of exercise as possible (this is your initial weight). Record the ambient temperature. Do your exercise session. Record the volume of any fluid you consume during your exercise session (fluid). Estimate (or measure!) urine losses during your exercise session (urine). Weigh yourself again at the end of your session, in the same clothing as before - be sure to towel off any excess sweat from your body first (this is your final weight). Your weight change during exercise, plus any fluids consumed, minus any urine losses, reflects your total fluid loss for that session. To work this out: Subtract your final weight from your initial weight. Add the weight of fluid (in kg) that you consumed while exercising. Subtract the weight of fluid (in kg) you lost through urination. To make this into an hourly rate, divide it by the number of hours you spent exercising.
Sweat rate (L/hr) = [initial weight (kg) – final weight (kg) + fluid (kg*) – urine (kg)] / time (hrs)
(*One litre of water or urine is equivalent to one kilogram.)
Remember, this is your sweat rate when exercising at a particular ambient temperature. Your sweat rate will change with the temperature, so it can be useful to measure your sweat rate at different times of the year.

Answer: The NEGATIVE CONTROL is the
test tube that is filled with ONLY distilled
water.
Explanation:
A negative control of an experiment is
carried out alongside the main primary
experiment except that the treatment is
changed to something that is predicted
to have no result. In the negative
control, the student does not expect any
response. This would help the student
compare the result of a new experiment
against an already known existing results.
Analysing the experiment carried out
by the student, She filled two test tubes
with distilled water and placed a piece
of Elodea in one of the tubes, leaving
the other without a plant. The other test
tube that contains only distilled water is
the negative control because she wasn't
expecting any result from it. It's also
served as a control sample to the primary
experiment. This is observed as she
blew in each tube to add carbon dioxide,
which caused the distilled water to
become more acidic. This would help the
student know that the that experimental
results are valid and to ensure that time is
saved
When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.Explain with the help of genetics why all fish turn dark blue.
Answer:
The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;
This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)

Answer:
Hello that's the answer and thank you
Explanation:
make me brainliest pls
Xylem and phloem are the types of tissues found in the vascular bundle of plants.
What is the vascular bundle of plants?
In animals, the bloodstream is used to transport nutrients throughout the body. This function is carried delivered via the vascular system, a network of tissues and fibers in plants.
The xylem and the phloem are the two primary tissue types that make up the vascular system. Water and dissolved minerals are distributed upward through the plant through the xylem, first from roots to the leaves. Food is transported from the leaves to the roots through the phloem.
A mature woody stem or root's principal component is made up of xylem cells. They are arranged vertically in the heart of the plant, creating a column that transports water and minerals taken up by the roots up the stem and onto the leaves.
Transporting the food that the leaves have produced downward via the stem is a similar network of phloem cells that line the outside of the xylem.
Therefore, the xylem and phloem are present in the vascular system of plants.
