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

Answer:

1. Carbohydrates - It serves several key functions in your body. They provide you with energy for daily tasks and are the primary fuel source for your brain's high energy demands. Fiber is a special type of carb that helps promote good digestive health and may lower your risk of heart disease and diabetes.

2. Protein- You use protein to make enzymes, hormones, and other body chemicals. Your body also uses protein to build and repair tissues. Protein is an important building block of bones, muscles, cartilage, skin, and blood.

3. Lipids - This is essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection

4. Nucleic acids are very important for cell functioning, and therefore for life. There are two types of nucleic acids, DNA and RNA. Together, they keep track of hereditary information in a cell so that the cell can maintain itself, grow, create offspring and perform any specialized functions it's meant to do.

Which of these is classified as an emerging virus that can have a direct impact on human health?
umka21 [38]

Answer:

The correct answer is: D. Ebola.

Explanation:

  • Ebola Virus is a single-stranded RNA (ribonucleic acid) virus.
  • The natural host of the virus is Fruit bat but it can also infect humans.
  • The transmission of the virus into humans is mediated from infected bats through body fluids.
  • The major disease caused by the virus is is Hemorrhagic fever. In this disease, the platelet (responsible for clotting of blood) count in the blood  drops far below normal. As a result, bleeding can get initiated both in the body interior or exterior. This disease can cause multiple organ failure and death.
  • Recently, in the year 2018, the Central African country, Democratic Republic of Congo experienced a severely fatal endemic due to the Ebola virus that killed many people within a short period of time.

1. Suppose that you take your boat offshore for a day of deep-sea fishing. You drop anchor at a supposed ‘hot spot’ and you noti
Mashcka [7]

The swim bladder is more or less an oval, soft-walled pouch located in the abdominal cavity, just below the spinal column. Its shape varies greatly, but the volume is constant between species, most often around 5% of body.

<h3>Day of deep-sea fishing</h3>

1. The volume of your swim bladder when you put it back in the water would be 7.5 liters.

2. The time the fish would float on the surface before the oval could restore neutral buoyancy would be a few seconds.

3. If I were a red blood cell that has just delivered its oxygen to the tail musculature of a mako shark, the route through the circulatory system to eventually reach the mako's swim bladder would be the venous route, like other fish, they have a heart with two chambers, an atrium and a ventricle, and closed circulation.

With this information, we can conclude that the volume of her swim bladder when she was put back in the water would be 7.5 liters.
