which statement best explains the genetic variation that results from sexual reproduction
a. each chromosome contains many copies of the same gene
b. offspring receive genes that are exactly the same as one parent’s genes
c. each chromosome contains many different genes
s. offspring receive a mix of genes from two different parents
Answer:
S. offspring recieve a mix of genes from two different parents
Offspring acquire genes that are exactly the same as one parent’s genes. Option B is correct.
Given that,
To choose the statement best explains the genetic variation that results from sexual reproduction.
Sexual reproduction is the process of creating new organisms by combining the genetic details of two individuals of different genders. The genetic details in most animals is carried on chromosomes in the nucleus of reproductive cells called gametes, which unite to form a diploid zygote.
Here,
The solution is due to the fact that each parent has two distinct sets of genes. Furthermore, each parent only passes on half of their DNA to their offspring. And that the half that is passed on is arbitrary. All of this ensures that each child is born with a distinct set of genes.
Thus, Offspring acquire genes that are exactly the same as one parent’s genes. Option B is correct.

A pen cap floats in a plastic lemonade 3/4 full of water vif you squeeze the bottle the pen cap sinks to the bottom if you then let go of the bottle the pen cap floats to the surfce whe the bottle squeezed what ,if anything happens to the distance between the air molecules inside the bottle????????/
Answer:
The pressure of the air molecules inside the pen cap increases and the volume occupied by the air decreases such that the combined volume occupied by the pen cap and the air volume reduces while the combined mass of the pen cap and the air molecules remain the same
Given that density = The mass/Volume, we have that the density varies inversely as the volume, and as the volume reduces, the density increases
Upon squeezing, therefore, as the new combined density of the pen cap and the air molecules rises to more than the density of the water in the bottle, then, the pen cap air molecule is relatively more denser than the water, which will result in the pen cap sinking to the bottom of the bottle

Davien and Jackson are headed to a beach that is 50km from school. At noon, Davien leaves his house that is 10 km closer to the beach than the school is and moves at 40 km/h. Jackson starts from school at 12:30 P.M. and moves at 100 km/h. What time does Davien reach the beach? *
Answer:
They both arrive at 1:00 PM
Explanation:
Amount Davien has to drive : 40km
Amount Jackson has to drive = 50km
Davien moves at 40km/h,
Therefore, it only takes Davien 1 hour to get there.
12:00 PM + 1 hour = 1:00 PM
Jackson moves 100km/h
He needs to drive 50 min, so 50/100 = 1/2
It takes him half an hour, or 30minutes
If he leaves at 12:30, then he gets there at 1:00 PM

An Inuit pushes a loaded dogsled with a mass of 600.0 kg over the frictionless surface of hard-packed snow. He exerts a constant 150.0 N force as he does so.
What is the sled's acceleration?
Given parameters:
Mass of Dogsled = 600kg
Force = 150N
Unknown:
Acceleration of the sled = ?
Solution:
Force is a physical quantity and can be expressed as a product of mass and acceleration.
Force = mass x acceleration
Since acceleration is unknown, we input the parameters and solve for it;
150 = 600 x acceleration
Acceleration = [tex]\frac{150}{600}[/tex] = 0.25m/s²
The acceleration of the sled is 0.25m/s²

A raven flies south for 100 seconds of 10m/s, then flies 0.50km north in 50 seconds. What is the total distance? What is the total distance? What is the average speed? What is the average velocity
Explanation:
given that the raven flies south for
time= 10 sec
speed= 10km/s
we know that speed=distance/time
distance=speed*time
distance=10*100
distance=1000m
distance=1km
also flies
distance=0.5km = 500m
time= 50 sec
speed= distance/time
speed=500/50
speed= 10m/s
speed= 0.01km/s
The average speed of an object is defined as the distance traveled divided by the time elapsed.
average speed= (1000+500)/10+50
average speed= (1500)/60
average speed= 25m/s
average velocity= (10km/s+0.01km/s)/2= 10.01/2= 5.005km/s
A boy pulls a wovon with a force or 6 Neast as another boy pushes it
with a force of 4 N east. What is the net force?
Answer:
The net force is 10 N.
Explanation:
A "net force" occurs when a particular object accelerates. It refers to the total number of forces that act on an object.
The boy pulling the cart and the other pushing it do their actions in the same direction. The force of pulling is 6 N while the force of pushing is 4 N. This means that the total force will not be cancelled.
To get the net force, add both forces since they are in the same direction (east).
Net force = 6 N + 4 N
Net force = 10 N (Newtons)

a pulley of radius 0.9m is used to lift a bucket from the well. if it took 3.6 rotations for the pulley to take water out of the well,how deep is water in the well?
Answer:
h = 20.36[m]
Explanation:
To solve this problem we must calculate the perimeter (length of a circumference) of the circumference, which is denoted by the following equation:
L = 2*π*r
where:
r = radius = 0.9[m]
π = 3.1416
L = 2*(3.1416)*(0.9)
L = 5.654[m]
Now we know that the pulley or circumference had to rotate 3.6 times to get the water out of the well. In this way the depth of the well can be calculated by means of the following equation:
h = 3.6*L
h = 3.6*5.654
h = 20.36[m]

Paco was driving his scooter west with an initial velocity of 4 m/s. He accelerates at 0.5 m/s for 30 seconds.
What is his final velocity?
O 2 m/s
O 8 m/s
O 19 m/s
O 60 m/s
Answer:
the answer is 19 ,30 (second) times 0.5= 15
15+4= 19
After Paco drives his scoter west with an initial velocity of 4 m/s and then accelerates at 0.5 m/s² for 30 s, his final velocity is 19 m/s, so the correct option is the fourth.
The final velocity of Paco can be calculated with the following equation:
[tex] v_{f} = v_{i} + at [/tex]
Where:
[tex] v_{f}[/tex]: is the final velocity =?
[tex]v_{i}[/tex]: is the initial velocity = 4 m/s
a: is the acceleration = 0.5 m/s²
t: is the time 30 s
Hence, the final velocity is:
[tex] v_{f} = 4 m/s + 0.5 m/s^{2}*30 s = 19 m/s [/tex]
Therefore, the correct option is 19 m/s.

Rita has two small containers, one holding a liquid and one holding a gas. Rita transfers the substances to two larger containers. Compare the behavior of the atoms in the liquid and in the gas once they are moved to the larger containers
Answer: liquids take the shape of the container they are in, but have definite volume. like liquids the shape of a gas changes with the container. unlike liquids the volume of a gas changes depending on the container it is in
Explanation:
Answer:
liquids flow freely, they take the shape of the container they are in, but have a definite volume. Like liquids, the shape of a gas changes with the container. This is because the atoms in a gas move rapidly and freely to fill any available space. Unlike liquids, the volume of a gas changes depending on the container it

What is a circuit ?Electronic components like resistors, circuitry, capacitors, inductors, and diodes are connected by conductive cables or traces that allow electric current to flow between them.
It is a specific kind of electrical circuit, and it is called as electronic rather than electrical, there usually needs to be at least each active component present.
In this circuit Signals can be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of factors and wires.
Electric current is generated by a power source like battery, and can travel through conductors such as wires, before returning to the power source. Electric circuits can be divided into two types: series and parallel circuits.

A plane lands and comes to a complete stop through 180 m of runway with a deceleration of 6.25 m/s2 [N]. Determine the plane’s velocity when it first touched the landing strip.
Answer:
47.43 m/s
Explanation:
Given that,
Final speed of a plane, v = 0
Distance, d = 180 m
Acceleration of the plane, a = -6.25 m/s² (deceleration )
We need to find the plane's velocity. Let it was u. So, using the third equation of kinematics as :
[tex]v^2-u^2=2ad\\\\u^2=0^2-2\times (-6.25)\times 180\\\\u=\sqrt{2250} \\\\u=15\sqrt{10}\ m/s\\ \\\text{or}\\\\u=47.43\ m/s[/tex]
So, the plane's velocity when it first touched the landing strip is 47.43 m/s.
