The function of the female reproductive system is to promote fertilization and serve as a container for the new individual until the end of its gestation.
What is the female reproductive system?It is in charge of physically and biochemically promoting the encounter between the sperm and the ovules generated by a female.
This union occurs in the uterus and, once the cells have been fertilized, a zygote is generated which, after nine months of growth, will become a new human individual.
Therefore, we can conclude that the female reproductive system differs from other body systems since it allows the fertilization of the ovum, pregnancy and the birth of a new individual.

What is the slope of the line tangent to the polar curve r=3θ at the point where θ=π2 ?
The slope of the line tangent to the polar curve r = 3θ at the point where θ = π/2 is; Undefined
What is the slope of the line tangent?
By converting into parametric equations, we have;
x(θ) = r(θ) cos θ = cos 3θ cos θ
y(θ) = r(θ) sin θ = cos 3θ sin θ
By product rule;
x'(θ) = -sin 3θ cos θ - cos 3θ sin θ
x'(π/2) = -sin 3(π/2) cos (π/2) - cos 3(π/2) sin (π/2)
x'(π/2) = 0
y'(θ) = -sin 3θ sin θ + cos 3θ cos θ
y'(π/2) = -sin 3(π/2) sin (π/2) + cos 3(π/2) cos (π/2)
y'(π/2) = 1
The slope m of the curve is gotten from;
m = y'(π/2)/x'(π/2)
m = 1/0
Thus the slope is undefined

The number of molecules of NO₂ that can be obtained when 2 molecules of NO react is 2 molecules
Balanced equationWe'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.
Thus, we can conclude that 2 molecules of NO₂ will be obtained from the reaction.

Jacob would like to purchase a coat and a hat for a ski trip. the coat is $62. 75 and the hat is $14. 25. if the sales tax rate is 8%, then what will be the amount of tax on jacob’s purchase?
The amount of tax on jacob’s purchase is $6.16.
What is Tax rate?Tax rate is simply the ratio at which a business or person is taxed.
To determine the amount of tax on Jacob’s purchase, we simply multiply the total purchase made by the tax rate.
Total purchase by Jacob; [tex]P = 62.75 + 14.25 = 77[/tex]
Sales tax rate; [tex]r = 8/100[/tex]
Hence, the amount of tax on jacob’s purchase is;

The ratio of hybrid cars to gasoline-powered cars in the parking lot of a local office building is 3:11. if there are 280 cars in the lot and one is to be selected at random to get the reserved parking space nearest the building, find the probability the car selected is a hybrid. express your answer as a fraction.
Answer:
The probability that it will be a hybrid is 21.4%.
Probability is the ratio of number of occurrences to total number of possible occurrences.
Given a total number of 280 cars. The number of hybrid cars is gotten by using the ratio.
Number of hybrid cars = (3/14) * 280 = 60 cars
Probability of picking a hybrid car = Number of hybrid car/total number of cars = 60 cars / 280 cars = 21.4%
Therefore the probability that it will be a hybrid is 21.4%.

Two skydivers of different masses jump from a plane. in three to five sentences, explain how their falls compare, including the effects of gravity, mass, and air resistance.
When a skydiver jumps out of a plane, the skydiver is said to accelerates down as a result of the force of gravity. No air resistance do acts in the upwards direction, and thus, the resultant force is said to be acting downwards.
Due to the above, the skydiver is known to moves or accelerates towards the ground.
How gravity and air resistance affect the motion of the skydiver?Note that before the parachute of a skydiver is opened, the air resistance is known to be more than the downward force of gravity.
