Answer:
15 hours and 40 minutes
Explanation:
The stages of mitosis are prophase, metaphase, anaphase and telophase. Anaphase is the stage of mitosis after metaphase where replicated chromosomes are segregated to opposite poles of the cell. Anaphase is the third stage after prophase and metaphase, which in this case have the same duration (20 minutes each one). In consequence, a cell that is just starting anaphase is 15 hours and 40 minutes old.
Interphase: 15 hours
Prophase: 20 minutes
Metaphase: 20 minutes
Knowing that interphase lasts 15 hours and each stage of mitosis lasts 20 minutes, we could say that a cell that is starting anaphase is 15 hours and 40 minutes old.
-------------------------------------
Available data:
The interphase lasts 15 hoursMitosis lasts 80 hours in totalEach stage of mitosis takes the same amount of timeNow, from the theoretical framework, we know that the interphase precedes the mitosis event.
We also know that mitosis is complete after four stages:
ProphaseMetaphaseAnaphaseTelophaseSo if the cell of interest is just starting anaphase, it means that it has already gone through the interphase. Then the cell has gone through the 15 hours that the interphase takes.
If mitosis is complete in 80 minutes, and each of the four stages lasts the same, we just need to divide 80 on 4 to get the amount of time each stage takes.
80 minutes / 4stages = 20 minutes/stage ⇒ Each stage takes 20 minutes
to complete.
This cell is just beginning the anaphase, which means it has already gone through prophase and metaphase. Each of them lasted 20 minutes.
So this cell has gone through 15 hours of interphase + 20 minutes of prophase + 20 minutes of metaphase = 15 hours and 40 minutes.
We can say that this cell is 15 hours and 40 minutes old.

Which of the following is not an example of sn adaptation
A. arctic rabbit's white fur
B.Person's Blue eyes
C.giraffe's long neck
D.Bears hibernating
Answer:
B. Person's blue eyes
Explanation:
In order for organisms to thrive in the environment, they have to undergo some changes. This process is called "adaptation."
A. The arctic rabbit's white fur is its adaptation to the cold environment in the Arctic area. Thus, this is adaptation.
B. A person's blue eyes doesn't have to do with adaptation; rather, it is connected to "genetics." Such genetic information is being carried by an individual from his/her parents. This makes it the only choice that is not an example of an adaptation.
C. The giraffe's long neck is its adaptation to eating from the treetops since it is a herbivore. This also prevents it from competing with other animals for food.
D. Bears hibernating is a proof of their adaptation to the winter season. Since food is scarce on these months, the bears try to sleep in order to stay alive. This also allows them to stay warm as well.
is this correct?????/????///??
Answer:
No.
Explanation:
You have mistaken C6H12O6 as Carbon Dioxide. However, this is glucose, so this is sugar. We do not inhale sugar, we obtain it from the food we eat or in the case of autotrophs, from producing it. Thus, the correct answer is C. from the food we eat.

A scientist places four identical cells into four different liquids, each with different concentrations of magnesium. Cell Description of Liquid Result W Slightly more magnesium than the cell Took in magnesium X The least amount of magnesium Took in magnesium Y Slightly less magnesium than the cell Took in magnesium Z The most amount of magnesium Took in magnesium Which shows evidence of active transport?
Answer:
The correct option is Z
Explanation:
Active transport can be described as the movement of molecules against a cell's concentration gradient; meaning the movement of molecules across the cell's membrane from a region of lower concentration to a region of higher concentration. From this, it can be deduced that to have active transport in the description in the question, the "body" (the cell or the liquid) with the most amount of magnesium took in more magnesium (showing movement against concentration gradient as the magnesium moved from the least side to the most side). Thus, the correct option is Z

Which correctly lists three places that fresh water is found?
Answer:
Ice caps and glaciers - 69%
Groundwater - 30%
Surface water - less than 1 %
Explanation:
Fresh water is a type of water, found in nature, in which there is no salt. It is water suitable for consumption (provided it is treated) for humans and animals. Fresh water is also used in agriculture. Only about 2.5% of the water found on our planet is sweet. It is mainly found in polar caps and glaciers, groundwater, surface water.
With the growth of the world population, fresh water has become increasingly scarce. Overuse, waste and water pollution are the main problems related to fresh water today.
As it is a precious and scarce mineral resource, society must be aware that, in order not to run out of water in the near future, it is necessary to avoid waste, use it rationally and do not pollute rivers, lakes and water sources.

Which statement about the waves shown is true?
The statement about the wave that is true is wave 3 has lowest frequency. The correct option is C.
What is frequency?The frequency of a repeating event is the number of occurrences per unit of time. It is distinct from angular frequency and is sometimes referred to as temporal frequency. The unit of frequency is hertz, which equals one event per second.
In science and engineering, frequency is an important parameter used to specify the rate of oscillatory and vibration phenomena such as mechanical vibrations, audio signals (sound), radio waves, and light.
The relationship between frequency and wavelength is inverse. The wavelength of the wave with the greatest frequency is the shortest.
One-half the wavelength equals twice the frequency. As a result, the wavelength ratio is inverse to the frequency ratio.
Thus, the correct option is C.

4. What is the mass of N2H4 gas in a 350.0 mL container at 50.0 °C, if the pressure of the gas is
885.0 torr?
Answer:
0.36g
Explanation:
Given parameters:
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = [tex]\frac{760}{885}[/tex] = 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = [tex]\frac{PV}{RT}[/tex]
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = [tex]\frac{0.86 x 0.35}{0.082 x 323}[/tex] = 0.01mole
So,
Mass = 0.01 x 32 = 0.36g

1. what is the difference between P waves and S waves?
2. How do you determine the difference between when a P wave and an S wave arrives at a seismogram location?
Answer:
P waves travels faster than S waves.
Explanation:
P waves travels faster than S waves. It can travel through any kind of material but s waves only travel through solid medium. P waves are smaller in size than s waves. P waves are the first waves to hit seismographs while the s waves are the second wave arrive at a seismogram location, so we can say that the wave which reach first at a seismogram location is the P waves. The speed of the wave shows which wave arrive first at a seismogram location.

2 ways us humans can relate to the digestive system. 5-6 sentences plzz and thank u
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.
Bacteria in your GI tract, also called gut flora or microbiome, help with digestion. Parts of your nervous and circulatory systems also help. Working together, nerves, hormones, bacteria, blood, and the organs of your digestive system digest the foods and liquids you eat or drink each day.
Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins, minerals, and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
Proteins break into amino acids
Fats break into fatty acids and glycerol
Carbohydrates break into simple sugars
