Explanation:
Maria wondered if different colors of plastic wrap affected the time for bread to mold. She wrapped a
slice of bread in clear plastic wrap. Before wrapping the bread she placed 5ml of water in the center of
the bread. She repeated the process with a slice of bread using red plastic wrap & a slice of bread using
blue plastic wrap. The bread came from the center of the same loaf. In each case she used the same
amount of water and the same brand of plastic wrap. She wrapped the different slices of bread in the
same way.

Previous research shows that, in humans, the pelvic opening tends to be wider in females than it is in males. Required:a. Generate a hypothesis about what causes this pattern.b. Describe the type or types of data you would ideally collect to test this hypothesisc. Describe what hypothesis data might support the hypothesis (For example, the hypothesis would be supported if we found data that indicated....)d. Describe what hypothetical data might regret the hypothesis and how would you rewrite your hypothesis to account for your findings and begin again.
Answer:
Throughout the clarification portion elsewhere here, the context of the query is explained.
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."This trophic level is the base for the
entire food web.

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?
--
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
Hydrogen bonds form between which types of elements?
Answer:
Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen. These three elements are so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient
Explanation:
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.
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

parts of the lipid bilayer?
A and D
A and E
B and C
C and D
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.

( 15 points! ASAP PLEASE ) Choose one of these two scenarios, and use the scenario to demonstrate the meaning of E = KE + PE. Assuming the total energy is 10 (10E), write the equation for each step outlined in the scenario you choose.
A child ready to slide down a slide
While sitting at top:
Half way down slide:
When reaching the bottom of slide:
A child on a swing
At highest point in swing:
Part way down arc:
At bottom of arc:
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.
