Overview
If you have a dry, flaking scalp, you may suspect dandruff. But it could be a sign of dry scalp. Dandruff and dry scalp have the same main symptoms, which are falling flakes and an itchy scalp, but they are two different conditions.
In dry scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed. Knowing which of these conditions you have can help you get the right treatment and banish those flakes for good.
Answer:
stratum corneum
Explanation:
its the outermost layer which generates dandruff (which is dead skin) skin grows from the inside, so it would make sense that the outermost layer releases dandruff/dead skin flakes

BRAINLIEST FIRST TO ANSWER What is the role of compound C?
A. a reactant that provides the energy for assembling sugars
B. a reactant that provides the carbon and hydrogen for sugars
C. a reactant that provides the carbon and oxygen for sugars
D. a product that forms along with sugars
Answer:
D
Explanation:
It's d because it shows it in the middle of the circle arrow thing.
Compound C is providing carbon and oxygen for sugar to make metabolic energy in photosynthesis, hence option c is correct.
What are carbon and oxygen for sugars?Atmospheric carbon dioxide gas, often known as CO₂, is the reactant in photosynthesis that supplies the carbon atoms needed to create glucose.
Water is the other reactant in this chemical process and it supplies the hydrogen that glucose needs. Water and carbon dioxide both contribute to the synthesis of oxygen.
Through the method of cellular respiration, organisms combine oxygen with food molecules, driving the chemical-stored energy, compound C.
Therefore, these substances toward life-sustaining processes while excreting carbon dioxide and oxygen hence option c is correct.

Explain why you know that diuron caused the coral to bleach.
Diuron will cause the coral to bleach. when the coral expels the algae that are living in their tissues.
Diuron simply refers to the trade name for DCMU which is an herbicide and algaecide ingredient that's used in controlling grasses and weeds. It should be noted that diuron affects the salinity of ocean water and this is where coral reefs propagate. This can bring about a long-lasting impact on corals.The algae which the coral polyps feed on is affected by the diuron and this brings about the bleaching of the coral. In this case, the exposure to higher diuron concentrations will lead to the pale or bleaching of corals.In conclusion, when the corals' bleach, it'll expel the algae that are living in their tissues and then turn to white.

Which object will require the greatest amount of force to change its motion?
A. A 63 kg object moving 27 m/s
B. A 75 kg object moving 22 m/s
C. A 55 kg object moving 32 m/s
D. A 72 kg object moving 25 m/s
The object with 72kgs weight will require the greatest amount of force i.e., 1800 N to change its motion to 25m/s. Thus, the correct option is D.
What is Force?
A force is an influence which can change the motion of an object. It is defined in the first law of motion that a body at rest will remain at rest and a body in motion will remain in motion until and unless an external force is applied on them.
A force can cause an object with a particular mass to change its velocity which causes acceleration. Force can also be described as a push or a pull. It has both the magnitude and direction which makes is a vector quantity.
Magnitude of Force which is applied to the object to cause its acceleration can be calculated by the formula:
F = m.a
where, F = Force
m = mass of an object,
a = acceleration of the object
By applying the values in the formula, we can calculate the amount of force to be applied.
a. m = 63kg, a = 27m/s
f = (63 × 27)
f = 1701 N
b. m = 75kg, a = 22m/s
f = (75 × 22)
f = 1650 N
c. m = 55kg, a = 32m/s
f = (55 × 32)
f = 1760 N
d. m = 72kg, a = 25m/s
f = (72 × 25)
f = 1800 N
The greatest amount of force is applied on the object in D option to change its motion.
Therefore, the correct option is D.
