There are many routes of administration that can deliver drugs directly to the developing fetus. The direct fetal routes of drug

administration are invasive in nature and should only be used when absolutely necessary. These routes should be employed for which of the following scenarios?
1. If passage through the placenta is adversely affected by fetal disease.
2. If the drug is not associated with maternal side effects.
3. If the drug easily crosses the placenta.
4. If rapid drug effects are required.

Answer:

The correct answer is option - 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

Explanation:

Normally the drug that is provided and administrated to the fetal is through the placenta of the mother. The direct delivery of medicine can be dangerous. However, with the advancement of the medical technology direct fetal drug administration is possible and it assists in the rapid uptake of the drug by the fetus.

If the fetus requires a rapid drug effect it can be provided by direct drug delivery. Also when the placental is not working properly and affected by the disease it is recommended to provide the fetus with the drug with the help of direct delivery.

Thus, the correct answer is : 1. If passage through the placenta is adversely affected by fetal disease. and 4. If rapid drug effects are required.

mariarad [96]

Most of the oxygen exiting the blood and entering the tissues does so from the capillaries.

Answer: Option D

<u>Explanation:</u>

The circulatory system consists of the heart, arteries, veins and capillaries. An artery is the one which carry blood from the heart to the organs. A vein is the one which carry blood from the organ to the heart.

A capillary is the smallest blood vessel which helps connect the functions of arteries and veins in the body. The capillaries are the narrow tubes which allow diffusion of Oxygen into and from the tissues. It’s prior function is to drop Oxygen in a tissue and collect the Carbon dioxide from the tissue.

how do engineers use models and earthquakes simulations to test designs for earthquake resistant buildings and structure
Oksana_A [137]

In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.

<u>Explanation:</u>

They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.

Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.

What is the wavelength of a wave with a frequency of 0.4 kHz traveling at 16 m/s?
larisa86 [58]

Answer: 0.04metres

Explanation:

The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ

Recall that Velocity (V) = Frequency F x wavelength λ

V = F λ

Make λ the subject formula

λ = V / F

In this case Frequency = 0.4 kHz

Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz

Velocity of wave = 16 m/s

So, λ = V / F

λ = 16 m/s / 400Hz

λ = 0.04metres

Thus, the wavelength of a wave is 0.04metres

creativ13 [48]

Answer: Option C) Animal

The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal

Explanation:

One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.

However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.
