The uterus gets ready to nurture a fertilized egg by

1 answer:

3 0

By flooding the uterus with a rich supply of blood for the tissue that lines the inner side of the uterus and it is called the endometrium. This happens each month during the menstrual cycle, when the body with the help of hormones which have different levels in the different times of the cycle. When it is time to prepare the uterus for a fertilized egg, the blood vessels of the endometrium swell and supply more blood to the tissue.

In the case that a fertilized egg cell reaches the uterus, it will attach itself to the endometrium and this is the place where the fetus, and then the baby will start growing. The endometrium is the base for the growth of the placenta which is the main and most important factor for protection and nutrition of the baby.

48 You are given two amplifiers, A and B, to connect in cascade between a 10-mV, 100-k source and a 100- load. The amplifiers ha

Sedbober [7]

Answer:

SABL

Explanation:

The best amplifier will be the one that gives us a bigger gain. In each stage will be a load factor that will reduce the gain, that is defined as:

$Fp=\frac{R_{in}}{R_{in}+R_{out}}\\$

where Rin is the input resistance of the next stage and Rout the output resistance of the previous stage.

Analyzing SABL:

$Fp_1=\frac{100K}{100K+100K}=0.5\\\\Fp_2=\frac{10K}{10K+10K}=0.5\\\\Fp_3=\frac{100}{100+1K}=0.0909$

the total gain will be the total gain of each stage multiplied by the load factor.

$SABL_{gain}=0.5*100*0.5*10*0.0909\\SABL_{gain}=22.73\\SABL_{gain_{db}}=20*\log{22.73}=27.13db$

Analyzing SBAL:

$Fp_1=\frac{10K}{10K+100K}=0.0909\\\\Fp_2=\frac{100K}{100K+10K}=0.909\\\\Fp_3=\frac{100}{100+10K}=0.0099$

the total gain will be the total gain of each stage multiplied by the load factor.

$SABL_{gain}=0.0909*10*0.99*100*0.0099\\SABL_{gain}=0.89\\SABL_{gain_{db}}=20*\log{0.89}=-1.01db$

So the best amplifier arrangement is SABL.

alexdok [17]

Answer:

D. wood, hydrogen gas, milk, and water

Explanation:

Waves will transmit through wood, hydrogen gas, milk and water.

Waves are disturbances that propagates energy usually through a material medium.

Most mechanical waves pass through the given medium. Only electromagnetic waves do not really require a material medium for their propagation. They can be propagated through a vacuum.
