Why the body needs more water after exercising/performing rigorous activity

Answers

Answer 1

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.

Answer 2

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.

For some parents, their offspring have larger beak depths; for others it's smaller. How does the concept of variation of traits help to explain this?

Answers

Answer:

beak depth is a complex (quantitative) trait

Explanation:

Additive effects refer to the resulting effects of two or more genes acting together. Beak depth is a quantitative trait whose variation is determined by the additive effects of many genes acting together and the environment. In quantitative traits, variation is continuous and produces a range of phenotypes. In consequence, in this case, some offspring will have a larger average beak depth compared to their parents, whereas others will have a smaller average beak depth compared to their parents. It is due to the combination of alleles or 'additive effects' inherited from different parents, and the interaction between these genes and the environment. Heritability refers to the proportion of quantitative trait variation due to additive genetic factors: a higher heritability is due to the predominance of additive genetic effects and less influenced by environmental effects.

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of elephants. Take away the elephants and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grassland. Given this, elephants can be defined as what type of species in this community

Answers

Answer:

The elephants are the keystone species in this ecosystem.

Explanation:

The elephants' job is to knock down trees from time to time to get food from tall stock. This prevents the trees from overpopulating and allows shrub lands to stay in place. This is important as herbivores can continue to graze in large herds and carnivores can continue using the same hunting strategies with little to no push backs by trees.

This makes to elephants a keystone species as without them, the foundation species will decrease in population and create a whole different ecosystem with the trees as the new foundation species.

As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis

Answers

Answer: Is a result of genetics and environmental factors.

Explanation:

Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.

A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.

Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.

So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.
