If 1/32 of a parent material is left, compared to 31/32 of daughter, and the half-life is 50,000 years, then how
old is the sample?
--
Answers
Answer:
251449 years
Explanation:
We can obtain the age of the sample by using the formula;
t1/2 = t ln2/ln(No/Nt)
Where;
t1/2 = half life = 50,000 years
t= elapsed time = the unknown
No = amount of radioactive material originally present
Nt= amount of radioactive material after time (t)
Note;
Since Nt/ No = 1/32
Then No/Nt= 32/1
Substituting values
t= t1/2 ln(No/Nt)/ln 2
t= 50000 × ln(32/1)/ln 2
t= 50000 × 3.47/0.69
t= 251449 years

The phospholipid bilayer is made of two parts, the head and tail. The head is hydrophilic whereas the tail is hydrophobic.
What is Phospholipid bilayer?Phospholipids, which are made up mostly of fatty acids and alcohol, make up the majority of the cell membrane. A phospholipid bilayer is the name given to the two layers of phospholipids that make up the cell membrane.
A phospholipid molecule has two tails and a head. The tails "detest" water, while the head "loves" it (hydrophilic) (hydrophobic). The water-loving heads point either toward the cytoplasm or the fluid surrounding the cell, while the water-hating tails are on the exterior of the membrane.
If the hydrophobic molecules are small enough, they can readily flow through the cell membrane as the inside of the membrane also despises water. Steroids and small lipids are hydrophobic and easily pass through the membrane.
Therefore, The phospholipid bilayer is made of two parts, the head and tail. The head is hydrophilic whereas the tail is hydrophobic.

Once M’Kenna’s small intestine healed, she started eating foods with dairy again and these foods no longer made her sick. Lactase is an enzyme that helps break down foods with dairy. In a healthy system, lactase is released from the tips of the villi in the small intestine. Using this information, make a prediction for why the damage caused by celiac disease causes problems when a person eats dairy.
Answers
Answer:
Damage to the villi means less lactase released, so the body can't break down dairy.
Explanation:
If the small intestine is damaged, then that can mean that the villi are damaged. The villi usually release lactase, so this process will be compromised.
Less lactase released means that the body will have less of the enzyme required to break down lactose, the sugar present in dairy. Thus, individuals with celiac disease will struggle to digest dairy products
Why is the structure of the neuron up to 1 meter long?
Answers
Answer:
The cell body of a motor neuron is approximately 100 microns in diameter and as you now know. the axon is about 1 meter (1,000) millimeter in length.
Explanation:
So the axon of a motor neuron is 10,000 times as long as the cell body is wide.

What would happen if a macromolecule was missing?
Answers
Answer:
If you were to not have any proteins in your being, you would eventually die. This is because all your cells need proteins to function. Without proteins, they cannot function.
Explanation:
If a macromolecule is missing, it will eventually affect your cell's functions and leads to the death of an individual.
What is a Macromolecule?A macromolecule may be defined as a type of very large molecule that is extremely important for the accomplishment of biophysical processes like metabolic functions, cellular needs, etc. Some examples of macromolecules are carbohydrates, proteins, nucleic acids, fats (lipids), etc.
According to the question, if macromolecules like carbohydrates are missing, the cells of an organism do not need energy for metabolic and cellular functions, and due to lack of energy, it will eventually die after some time. The same principle is followed by the other macromolecules as well.
Therefore, if a macromolecule is missing, it will eventually affect your cell's functions and leads to the death of an individual.

Half way down slide:
When reaching the bottom of slide:

At highest point in swing:
Part way down arc:
At bottom of arc:
Answers
Answer:
I choose the slide so here is the answer
Explanation:
At the highest point: 10E = 0KE + 10PE
Part way down: 10E = 5KE + 5PE
At bottom: 10E = 10KE + 0PE
In both the scenario, the object will experience different P.E. and K.E. at different situations.
At the highest point: 10E = 0KE + 10PE
Half-way down: 10E = 5KE + 5PE
At bottom: 10E = 10KE + 0PE
What is Total Energy?The total energy of a body is the sum of its potential energy and kinetic energy. Potential energy is the stored energy in any object or system. This energy is not affected by the external environment including air and height.
On the other hand, Kinetic energy is the energy present in a system or object which is in motion. The formula for the determination of potential energy and kinetic energy are as follows:
E = K.E. + P.E.
where, E = Total energy of an object
K.E. = Kinetic energy of an object
P.E. = Potential energy of an object
K.E. = 1/2m.v²
where, m = mass of an object
v = velocity of an object
P.E. = m.g.h
where, m = mass of an object
g = acceleration due to gravity
h = height
In the given scenario, while sitting at the highest point: 10E = 0KE + 10PE (K.E. is zero as the body will come at rest v = 0)
Half- way down: 10E = 5KE + 5PE (body will experience both P.E. and K.E.)
At bottom: 10E = 10KE + 0PE (Here, the height is zero hence P.E. is zero)
Same goes with the child swinging.

Explanation:
(a)
Null Hypothesis: The distance including its pelvic area between women and men does not vary.(b)
The X-ray as well as CT-scan of 20 stable people from various age categories will be obtained from the pelvic area. We're going to get statistics on the same combination of women and men. Way of measuring and cross-reference the pelvic area however according to gender. To assess the degree of importance, submit statistical measures (T-test).(c)
The width including its pelvic region must've been identified and therefore should not vary substantially throughout males and females to validate the data.(d)
Although we consider that the disparity in men's and women's pelvic regions is substantially different, the theory will be dismissed. Let's say the theory has been dismissed. But now the latest theory would be that "Women throughout the pelvic region are larger versus men."Which two phrases describe the nature of an electromagnetic force?

how can temperature and precipitation affect tree growth
Answers
Answer:
When there is present low precipitation or low moisture supply, together with high temperature, the limited growth is due to the close relationship which exists between turgidity and growth.
Explanation:
It is known, of course, that precipitation and temperature are not the only factors that have an effect on the growth of trees.
Answer:
Temperature can affect how heat and other gases correspond with the tree and can change the flow inside the tree. Precipitation can tell us how much water the tree is getting to absorb and grow with.
