where do duplicated chromosomes line up during metaphase?

Answers

Answer 1
During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.

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

Answers

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.

The answer would be natural selection.

A mouse population that is originally white in color becoming darker in color after several generations is an example of natural selection.

What do you mean by natural selection?

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.

Answer:

D. Design a device that can throw an object at least 15 meters.

Explanation:

First of all, the object shown as you may be able to tell, look like a catapult. It also shows the top end of it holding a ball, getting ready to launch it. It then shows a line of the ball traveling after being launched. The balls land of the ground at 15 meters. From this iformation you look at the options:

A. Design an object that is 10 meters tall.

No, because 10 meter is just the highest point of the ball being launched.

B. Design a vehicle that can travel across a 10-meter feild.

No, because it is the ball that is traveling, not the catapult.

C is about a vehicle traveling again, so eliminate that too.

D. Design a device that can throw an object at least 15 meters.

This describes exactly what we soo in the picture. Meaning D is correct.

In humans, freckles are encoded by a dominant allele. A woman is heterozygous for freckles. According to the law of segregation, allele pairs separate during gamete formation and then randomly unite during fertilization. Which of the following would apply to this woman's child?

Answers

The child having an equal chance of inheriting the dominant allele or the

recessive allele for freckles from her mother is what applies.

The law of segregation by Mendel states that diploid organisms have a pair

of alleles and are passed to their offspring at random.

The woman being heterozygous means she has the dominant and recessive

allele present. Due to the law of segregation stating the alleles are passed

at random to the offspring, the child will have an equal chance of inheriting
