Determine the value of x. A 9.75 B 11 C 22 D 19.5
A. The value of x in the given circular geometry is determined as 9.75.
Value of x in the geometry
The value of x can be calculated by applying the following rules of geometry as shown below.
angle AC = angle at the center
angle at center = twice angle at circumference
147 = 2(6x + 15)
147 = 12x + 30
147 - 30 = 12x

How is gamete division related to chromosomal abnormalities?
Extensive gamete division causes chromosomal abnormalities.
• Failed gamete division causes chromosomal abnormalities
• Uneven gamete division causes chromosomal abnormalities.
• Even gamete division causes chromosomal abnormalities.
The uneven gamete division causes chromosomal abnormalities.
What is a Gamete?A gamete is a fully developed reproductive or sex cell with haploid chromosomes that has the capacity to mate with another haploid gamete to create a diploid zygote. The fusion (or combining) of two gametes, namely a male and a female gamete, results in the zygote. Fertilization is the process through which two gametes combine to form a zygote.
One of the gametes is typically bigger and non-motile, which is characteristic. It is sometimes referred to as an ovum or an egg cell. The second gamete cell is smaller and motile. It is also known as a sperm cell or a male gamete. In humans, each gamete has 23 chromosomes, and when they fuse, a diploid zygote with 46 chromosomes is created. These reproductive cells are created in the gonads, or reproductive organs, of the male and female animals. The male gametes in seed-bearing plants are the pollen, whereas the female gametes are housed in the plant's ovules. The gamete in plants, however, is not invariably a haploid cell.
Hence, Uneven gamete division causes the chromosomal abnormalities.

Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. Energy is released in the sun’s core through Response area. It then is transferred by Response area through the sun’s radiative zone to the conductive zone, where it is transferred to the sun’s surface by Response area. From the surface, energy from the sun is transferred to Earth by Response area.
The correct answer is nuclear fusion, radiation, and conduction.
It is a nuclear process in which energy is produced by colliding light atoms. It is the opposite of fission, which results in the disintegration of heavy isotopes. The sun and other stars produce light and heat through fusion.
According to the energy of the emitted particles, radiation is frequently classified as either ionising or non-ionizing. More than 10 eV is often carried by ionising radiation, which is sufficient to ionise atoms and molecules and rupture chemical bonds.
Conduction is an observable occurrence in all states of matter and is the process of transmitting energy through the motion of particles in touch with one another (solids, liquids and gases). Conductors are substances that permit conduction. Conduction is divided into three categories: conduction of heat, conduction of electricity, and conduction of sound.

Two birds are flying south for the winter. Bird 1 reaches its destination in 6 hours, while bird 2 reaches its destination in 12 hours. If bird 2 covers twice as much distance as bird 1, what is the ratio of their average speeds (bird 1/bird 2)?
1.0
0.8
1.2
0.5
The correct answer is option ( A) the ratio of their average speeds (bird 1/bird 2) is 1.0
velocity = distance / Time
Let us assume distance covered by Bird 1 = d
case 1 (Bird 1) :-
time = 6 hours
velocity(Bird1) = d/6 = 0.167*d
case 2 (Bird 2) :-
time = 12 hours
distance is twice of Bird 1 = 2d
velocity(Bird2) = 2d/12 = 0.167*d
now, velocity of Bird1/Bird2 = (0.167*d)/(0.167*d) = 1.0
So,velocity of (Bird1/Bird2) is 1.0 .
Average velocity / Average speed = Total displacement / Total distance. Remember that the numerator is less than or equal to the denominator. As a result, the ratio is always equal to or less than one. Distance traveled divided by time taken is the most commonly used formula for calculating average speed. The other formula is to add the initial and final speeds together and divide by two.

Water at rest exerts a force known as hydrostatic pressure. It is caused by the water's continual pressure on the basement walls.
The force that blood applies to blood channel walls is a typical illustration of hydrostatic pressure.
Depending on the liquid's density ('ρ'), the height of the water column ('h'), and the acceleration caused by gravity ('g'), the hydrostatic pressure is indicated by the letter "P" of a liquid column.

Which graph best describes the cliff jumper’s vertical displacement over time?
THE ANSWER IS IN THE ATTACHMENT!
The graph C best describes the cliff jumper's vertical displacement as shown in the attachment.
The initial vertical velocity of the cliff jumper would be zero as the cliff jumper runs off the cliff horizontally. As he jumps off, he is subjected to gravitational pull. This increases his velocity with respect to time.
During some of the initial time, the displacement would be lesser as his velocity increases with increase in time. Also the graph is in the 4th quadrant because the vertical displacement is downwards ( Negative ) as the time increases ( Positive ).
