the process of mitosis makes body cells which are also called_______ cells.
NEED DONE ASAP!!!!!
Answer:
daughters cells
Explanation:
when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.
in each of the following divide the second number by the first number and find the quotient:3/4,-3/8
Answer:
[tex]\dfrac{-1}{2}[/tex]
Explanation:
We need to divide the second number by the first number and the numbers are 3/4,-3/8.
First number = 3/4
Second number = -3/8
Dividing the second number by the first number.
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]
So, the answer is (-1/2)
Suppose that the ultrasound source placed on the mother's abdomen produces sound at a frequency 2 MHz (a megahertz is 10^610 6 Hz). Sound travels through tissue at roughly the same speed as in water (v\approx 1500v≈1500m/s). Find the maximum change in frequency between the sound that is emitted by the device and the sound that is observed at the wall of the baby's heart. Treat the heart wall as a moving observer. Hint: you will need to use your answer from part (a). Give your answer as a positive number in Hz.
Answer:
the maximum frequency observed is 2.0044 10⁶ Hz
Explanation:
This is a Doppler effect exercise. Where the emitter is still and the receiver is mobile, therefore the expression that describes the process is
f ’= [tex]f_o \ ( \frac{v \pm v_o}{v} )[/tex]
the + sign is used when the observer approaches the source
typical speeds of a baby's heart stop are around 200 m / min
let's reduce to SI units
v₀ = 200 m / min (1 min / 60 s) = 3.33 m / s
let's calculate
f ’= 2 10⁶ ([tex]\frac{1500 \ \pm 3.33}{1500}[/tex])
f ’= 2.0044 10⁶ Hz
f ’= 1,9956 10⁶ Hz
therefore the maximum frequency observed is 2.0044 10⁶ Hz

What is velocity ratio? It is impossible to get a perfect machine in practical life, why?
Explanation:
VELOCITY RATIO :- The ratio of a distance through which any part of a machine moves to that which the driving part moves during the same time.When a charge moves between
two points that have a potential
difference of +12.0 V, its electric
potential energy increases by
0.418 J. What is the amount
of the charge?
Include the correct sign, + or -
(Unit = C)
Answer:
+ 0.07 C
Explanation:
From the question given above, the following data were obtained:
Potential difference (V) = 12 V
Energy (E) = 0.418 J
Charge (Q) =?
The energy (E) , potential difference (V) and charge (Q) are related by the following equation:
E = ½QV
With the above formula, we can obtain the charge as follow:
Potential difference (V) = 12 V
Energy (E) = 0.418 J
Charge (Q) =?
E = ½QV
0.418 = ½ × Q × 12
0.418 = Q × 6
Divide both side by 6
Q = 0.418 / 6
Q = + 0.07 C
Answer:
.0348

Why does our sun appear larger than any other star in our galaxy
PLS HELP & use your own words thanks
Answer:
The closer and bigger the star, the larger the star appears.
Explanation:
Since the sun is closer to us it shows up way larger than other stars in our galaxy.
Have a great day.
Answer:
It is the closest star to us. other bigger stars may seem small, but that is because they are far away. The more closer an object is, the smaller it seems to be.
