Number of chromosomes?
DerKrebs [107]
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>KAROTYPE:</h2>

This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.

<h2>_____________________________________</h2><h2>CHROMOSOMAL NUMBER 18:</h2>

Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.

<h2>_____________________________________</h2><h3>TRISOMY 18:</h3>

Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.

What is the boundary between the earths lower mantle and the upper mantle called ?
Alenkasestr [34]

Answer:

i have trusted my best to answer

Explanation:

Edit

The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A. What is the resi
blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω
