Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The chromosomes of the 23rd pair are called allosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males.

Ek = 12 x m X v2. Re-arrange to give an equation for:
a) The mass m.
b) Velocity squared v2.
c) Velocity.
Answer:
a) [tex]m = \frac{2\cdot E_{k}}{v^{2}}[/tex], b) [tex]v^{2} = \frac{2\cdot E_{k}}{m}[/tex], c) [tex]v = \sqrt{\frac{2\cdot E_{k}}{m } }[/tex]
Explanation:
a) Translational kinetic energy ([tex]E_{k}[/tex]), measured in joules, is represented by the following expression:
[tex]E_{k} = \frac{1}{2}\cdot m \cdot v^{2}[/tex] (1)
Where:
[tex]m[/tex] - Mass, measured in kilograms.
[tex]v[/tex] - Velocity, measured in meters per second.
Now we clear the mass within the formula:
[tex]E_{k} = \frac{1}{2}\cdot m\cdot v^{2}[/tex]
[tex]2\cdot E_{k} = m\cdot v^{2}[/tex]
[tex]m = \frac{2\cdot E_{k}}{v^{2}}[/tex]
b) Now we clear the velocity squared:
[tex]v^{2} = \frac{2\cdot E_{k}}{m}[/tex]
c) Now we clear the velocity:
[tex]v = \sqrt{\frac{2\cdot E_{k}}{m } }[/tex]

Cyclist 1 pedals 40 kilometers east in 2 hours. Cyclist 2 pedals 10 kilometers west in half an hour. Based on this information, which statement about cyclists is correct?
Answer:
See Explanation
Explanation:
Given
Cyclist 1:
[tex]Distance = 40km[/tex]
[tex]Time = 2hr[/tex]
[tex]Direction = East[/tex]
Cyclist 2:
[tex]Distance = 10km[/tex]
[tex]Time = 0.5hr[/tex]
[tex]Direction = West[/tex]
The question requires options. Since none is given, I'll answer on a general term.
First, calculate the speed of both cyclists
[tex]Speed = \frac{Distance}{Time}[/tex]
Cyclist 1:
[tex]Distance = 40km[/tex]
[tex]Time = 2hr[/tex]
[tex]Speed = \frac{40km}{2hr}[/tex]
[tex]Speed = 20km/hr[/tex]
Cyclist 2:
[tex]Distance = 10km[/tex]
[tex]Time = 0.5hr[/tex]
[tex]Speed = \frac{10km}{0.5hr}[/tex]
[tex]Speed = 20km/hr[/tex]
The following can be deduced from above:
Both cyclists travel at the same speed of 20km/hrBoth cyclists travel in opposite directions

Which situation represents the highest entropy of a deck of playing cards?
O A. In four piles, organized by suit
B. Stacked in a deck
C. In order of face value
D. Scattered over the ground
SUBMIT
Answer:
D.
Explanation:
Entropy is the measurement of disorder in a system. The greater the entropy the more disorder/mess there is. Options A B and C all have organized systems so D is the only one with the least orderly scenario
Scattered over the ground represents the highest entropy of a deck of playing cards.
What is entropy?Entropy is a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
Entropy is the measurement of disorder in a system. The greater the entropy the more disorder/mess there is. Options A,B and C all have organized systems so, D is the only one with the least orderly scenario

What is the mass, in grams, of 2.00 moles of H2O?
Answer:
36g
Explanation:
Given parameters:
Number of moles of H₂O = 2moles
Unknown:
Mass of H₂O = ?
Solution:
To solve this problem, use the expression below:
Mass of H₂O = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of H₂O = 2 x 18 = 36g

Ill mark the brainliest pls lmk what answer ty
2800 m
Further explanationGiven
time = 80 s
average velocity = 35 m/s
Required
total distance before it broke down
Solution
Average velocity : total displacement : total time
Can be formulated
avg velocity = Δx : Δt
Input the value :
Δx=avg velocity x Δt
Δx = 35 m/s x 80 s
Δx = 2800 m
In addition, if we are asking for velocity, we must know the starting and ending points (displacement)
But if we calculate the total distance, what is written is the average speed
avg speed = total distance : total time

Answer:
I found it would be quadrupled if it was doubled
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion. It is given by:
where
m is the mass of the object
v is its speed
From the equation, we notice that the kinetic energy is:
Directly proportional to the mass
Proportional to the square of the speed
In this problem, the initial kinetic energy of the object is
K = 100 J
Later, the speed of the object is doubled:
v' = 2v
Therefore, the new kinetic energy will be
So, we see that the kinetic energy will quadruple.
what is the acceleration of an object if the object has an initial speed of 230 m/s and speeds up to 650 m/s. The time it takes for this to happen is 30 seconds

The results suggested that the diameter of the nucleus of a gold
the diameter of the atom.
The diameter of a gold atom is 0.18 nm
Calculate the diameter of a gold nucleus in nm.
Answer:
The diameter of the gold nucleus is 3.0 × 10⁻⁵ nm
Explanation:
The given parameter of the gold atom are;
The diameter of the gold atom = 1/6,000 × The diameter of the atom
The diameter of a gold atom = 0.18 nm
The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 1/6,000 × 0.18 nm = 0.00003 nm
∴ The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 0.00003 nm = 3.0 × 10⁻⁵ nm.

The whale shark the largest of fish and can have the mass of three adult elephants. Suppose that a crane is whale shark into a tank for delivery to an aquariumThe crane must exert an unbalanced force of 2.5 * 10 ^ 4 to lift the shark from rest. If the shark's acceleration equals 1.25 m/s ^ 2 , what is the shark's mass?
Answer:
Mass, m = 20000 kg
Explanation:
The force acting on the shark, [tex]F=2.5\times 10^4\ N[/tex]
Acceleration of the shark, a = 1.25 m/s²
We need to find the mass of the Shark. The force acting on an object is given by :
F = ma
m is the shark's mass
So,
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg[/tex]
So, the mass of the Shark is 20000 kg.
