Open Question: What is the point of a chicken laying an unfertilised egg?

Open Question: What is the point of a chicken laying an unfertilised egg?

None. But in the wild, almost all eggs are fertilized in birds... Chickens are jungle birds originally. Man domesticated them. Now they are warehoused in huge buildings, their reproductive system hijacked for your morning breakfast.

Many live their whole lives in cages, never touching the ground.

Human equivalent, yes probably menstruation. During most of human history, the average woman had 13 pregnancies, and 9 live births in her life time. She was lucky to raise two to teenagers. This is still the case in areas of no "imported" medicine, such as the bush of Africa, or the rain forests of the world.

Modern medicine in First world countries now saves most babies, and most mothers.

Open Question: Point of saturation of Sucrose solution?

Open Question: Point of saturation of Sucrose solution?

Home >All Categories > Science & Mathematics >Chemistry >Open QuestionLottie Lottie Member since:August 02, 2009Total points:642 (Level 2)I'm doing an investigation for school, and I need to find the point of saturation of sucrose in water at room temperature (roughly 25 degrees celsius). I've found the molar mass and all of this stuff to try and work it out but I keep getting ridiculous figures like 0.05m, which can't be right because we did an experiment with 1mole solution and that was not saturated. So i'm sort of confused.. if anyone could tell me what the point of saturation of sucrose in water is at 25 degrees celsius (in moles) is, that would be much appreciated. Thanks in advance.Answer Question

Open Question: Calculus: Find an equation of the tangent line to the curve at the given point?

Open Question: Calculus: Find an equation of the tangent line to the curve at the given point?

f(x) = (1 + 2x)¹° so f '(x) = 10(1 + 2x)? •2 = 20(1 + 2x)?

Since the point is (0,1) the slope at that point is f '(0) = 20(1)? = 20

So using the point-slope form of the line

y – 1 = 20(x – 0) or y = 20x + 1

Open Question: Is our body made up of the exact same atoms from birth or at one point completely different atoms?

Open Question: Is our body made up of the exact same atoms from birth or at one point completely different atoms?

I don't know how to phrase this proper but we're all made up of atoms right and we grow from the air we breath and food we eat right. But we also shed skin get cut, excrete & urinate etc. So is it possible that at one point in life are whole body is made up of competely different atoms to the ones we were born with or lets say most. Or is DNA always the exact same atoms from the start and only gaining new ones.

Bassically are we made up of the exact same material throughout life or what?

Open Question: A student determines the isoelectric point ...?

Open Question: A student determines the isoelectric point ...?

A student determines the isoelectric point (the pH corresponding to zero net
charge) of a protein in an aqueous solution by lowering the pH until
precipitation of the protein is observed. During this process, the student
records an initial pH of 6.25 (protein is in solution), then upon addition of
acid, the pH decreases to 5.75 and the protein is found to have precipitated
from solution. The student should record the isoelectric point of the protein
as:

a. 6.00 ± 0.50
b. 6.00 ± 0.25
c. 5.75 ± 0.50
d. 6.25 ± 0.25
e. 5.75 ± 0.25

Open Question: What is the y-intercept formula for the following graph point data?

Open Question: What is the y-intercept formula for the following graph point data?

You defined x= 0 at the year 1920.

Therefore, you have the equation:

y= -.02x + (y-intercept)

If you plug in the values for 1920, you get:
46.6= -.02(0) + (y intercept)

The y-intercept is 46.6.

This also works if you plug in x= 60 years and 45.4 seconds.

So no, your answer is not correct. Sorry :(
