Why is there a higher pressure in the afferent arteriole than the glomerulus in a healthy individual?
Answer:
The myogenic response is the reflex response of the afferent arterioles to changes in blood pressure. Increased blood pressure increases the tension in the vascular wall, and the vascular smooth muscle contracts. Similarly, decreased blood pressure decreases the tension and the smooth muscle relaxes.

The microscope has an eyepiece lens with a x10 magnification and three objective
lenses: x4, x10 and x40.
Describe the best method of using the microscope to focus on the plant tissue and reach
a magnification of x400.
Answer:
1. Set up the microscope with the slide prepared.
2.Use 10x40=400
Explanation:
Prepare the slide and set up the microscope. Use 10x40=400
What is microscope?Microscope is defined as an optical device that magnifies an item using a lens or combination of lenses. They aid in viewing many organisms as well. A microscope's light also makes it easier to see bacteria. We use microscopes to examine items more closely and see details that aren't visible to the eye. We wouldn't know about the existence of cells, how plants breathe, or how rocks evolve over time without them.
You can see the slide more clearly than with a scanning objective lens without getting too close for general viewing thanks to the 100x total magnification that a low power objective lens and a 10x eyepiece lens provide. The sum of the magnifications from the two lens systems is the overall magnification. As a result, the 10X objective and 10X ocular lenses on the microscope would magnify the object by 10 x 10 or 100 times.
Thus, prepare the slide and set up the microscope. Use 10x40=400

Answer:

Explanation:
A species of moth has a 2 varieties of wing color: brown and white. As winter approaches, the trees where the moths live loose their leaves. The moth's predators are birds who hunt for the moths as they rest on the dark tree bark. Every moth lays 100 eggs, but only about 10 from each egg cluster live to adulthood
Assuming that this question makes reference to the survivability of the two moth variations, we can confirm that the brown-colored moth will be better adapted to survive in the winter months.
Why are the brown moths more likely to survive?This has to do with their ability to better hide from predators. As described in the question, their primary predator are birds that hunt them while resting on the tree bark. This means that the white-colored moths will stand out against the dark tree bark and be easier prey for the birds. This will eventually lead to all the moths in the area being brown-colored through the process of natural selection.
Therefore, we can confirm that the brown-colored moth will be better adapted to survive in the winter months due to their ability to hide from predators.

Lantern fish live in the middle ocean depths where there is no sunlight. which example is a response to this dark environment? question 10 options: camouflage that allows them to blend in to their surroundings a light producing organ to attract mates and prey mimicking other deep sea animals in order to catch prey hibernating when the water temperature becomes too cold
Answer:
A lighting producing organ to attract mates and prey.
Explanation:
Camouflage would do very little for a fish that spends most of it's day in the middle of a dark ocean. Mimicking other deep sea creatures would actually be more of a disadvantage than an advantage, as the sounds would be more likely to scare away potential prey, rather than attract them. A light however, would attract the prey's curiousity and urge them to check out the light.

Given that a virus divides every 3 hours, and that a cell lyses (explodes) after it reaches a viral load of 5,000,000 units, how long will it take a virus starting at 1500 units to lyse the cell
The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
How to calculate the Exponential growth/decay formula?x ( t ) = x 0 × (1 + r ) t
x(t) is the value at time t.x 0 is the initial value at time t = 0.r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.t is the time in discrete intervals and selected time units.Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
