Chelsea is a chemist working with a research company trying to create a treatment for Alzheimer’s. Chelsea knows that this is a

neurodegenerative disorder, in which the brain starts breaking connections between neurons over the course of a long period of time. Chelsea focuses her research on making precise measurements of the length of time a patient generally will undergo before the symptoms become severe. Her idea is to create a drug that can be administered just before the onset of severe symptoms, halting the effects altogether. This is very different from most researchers in her field, who are trying to prevent the disease, which is proving to be more impossible than not.
Is it a Empirical, Tentative, Observation vs Inference, Creative or a Subjective article

5 0

Answer:

I'm thinking observation vs inference

Explanation:

she does her research about the situation and then comes up with an idea. the idea can be seen as an inference since at the end of the article it says "proving to be more impossible than not", which leads me to believe it's more of an observation vs inference situation.

The sole of a gecko's foot is covered with millions and millions of small, dry "hairs" that make direct contact with surfaces, a
tamaranim1 [39]

Answer: Van der Waals forces

Explanation:

Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.

The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.

Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.

Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.

Suppose that the resistance between the walls of a biological cell is 7.0 × 109 Ω. (a) What is the current when the potential di
DIA [1.3K]

Answer:

Explanation:

Using Ohm's law

V ( voltage) = I (current A) × Resistance R in ohms

R = 7.0 × 10⁹Ω

V = 80 mV = 80 / 1000 = 0.08 V

0.08 V = I × 7.0 × 10⁹Ω

a) I = 0.08 V / 7.0 × 10⁹Ω = 1.142857 × 10 ⁻¹¹ A

b) quantity of charge = I × t = 1.142857 × 10 ⁻¹¹ A × 0.85 s = 9.7142857 × 10⁻¹² C

number of Na⁺ ions ( q = +e) = 9.7142857 × 10⁻¹² C / 1.6 × 10⁻¹⁹ C = 60714285.714 Na⁺ ions
