Cells comprise all living things. Multicellular mammals, plants, and fungi are examples of multicellular creatures. Unicellular microorganisms include bacteria and archaea.
All kinds of creatures can have the capacity for procreation, growth and development, maintenance, and to some extent, stimulus-response. Multicellular organisms such as beetles, tetrapods, mushrooms, and vascular plants grow a variety of tissues and organs.

Explanation:
a child riding a bicycle at 15 meters per second accelerates at -3,0 meters per second? for 4.0 seconds. What is the child's speed A at the end of this 4.0-second interval? (with work, all steps))
Answer:
27m/sExplanation:
Given data
initital velocity u=15m/s
deceleration a=3m/s^2
time t= 4 seconds
final velocity v= ?
Applying the expression
v=u+at------1
substituting our data into the expression we have
v=15+3*4
v=15+12
v=27m/s
The velocity after 4 seconds is 27m/s

what does 1N equal? It happens to be one of the questions on my "Newton's Laws of Motion Exercises" paper.
An object is dropped from 20. meters above the moon. The acceleration due to gravity on the moon is 1.62 m/s^2
a. How long does it take for the object to impact the moon?
b. At what speed does it impact the moon?
Answer:
a. Approximately 3.21 seconds
b. Approximately 5.196 m/s
Explanation:
a. The height from which the object is dropped = 20 meters
The location of the occurrence = The moon
The acceleration due to gravity on the moon = 1.62 m/s²
The time it took the object to to impact the moon is given by the equation of free fall as follows;
h = 1/2·a·t²
Where;
h =The height from which the object is allowed to freely fall = 20 meters
a = The acceleration due to gravity on the moon = 1.62 m/s²
t = The time of motion of the object
Substituting the values, gives;
20 = 1/2 × 1.62 × t²
t² = 20/(1.2 × 1.62) ≈ 10.23 s²
t = √ 10.23 ≈ 3.21 s
The time in motion of the object before impact, t = 3.21 seconds
b. The final speed, v is given from the equation for speed under free fall, which is presented as follows;
v = u + a·t
Where
u = The initial vertical velocity = 0
Substituting the values gives;
v = 0 + 1.62 × 3.21 ≈ 5.196 m/s
The final speed, v with which the object impacts the moon ≈ 5.196 m/s

Remi travels 160 meters in 4 seconds. What was Remi's initial speed if her final velocity was 6.9 m/s?
Answer:
73.1 m/s
Explanation:
Given:
Δx = 160 m
v = 6.9 m/s
t = 4 s
Find: v₀
Δx = ½ (v + v₀) t
160 m = ½ (6.9 m/s + v₀) (4 s)
v₀ = 73.1 m/s

Which two statements describe reasons a solar cell must contain semiconductors?
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.
B. Semiconductors reflect all forms of electromagnetic radiation.
C. Semiconductors serve as a source of electrons to form an electrical current.
D. Current flows from the positively charged semiconductor to the air above the glass covering
Two statements describe reasons a solar cell must contain semiconductors :
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.
C. Semiconductors serve as a source of electrons to form an electrical current.
What is Photoelectric effect?Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
When the semiconductor is exposed to light, it absorbs energy and transfers it to the material, due to which energy reaches to negatively charged particle (electron), which allows the electron to flow in the material as electric current .
hence , correct option will be :
A. Semiconductors form a path for the electrons that are released by the photoelectric effect.
C. Semiconductors serve as a source of electrons to form an electrical current.

Explanation:
What are the relationships between the different wave properties (frequency, wavelength, wave speed, period, amplitude)
Ex) As ___ increases, ___ increases/decreases/remains the same.
Answer:
As frequency (cycles per second) increases the wavelength decreases.
As frequency increases the period also decreases
If wave speed or velocity increases, so too does the frequency
Amplitude of a wave is totally independent of frequency, period etc. So it remains the same as frequency shifts. Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.
Explanation:
F= 1/t Frequency is inversely proportional to time (wavelength)
Period is the time it takes for one wave cycle to complete Period is 1/f
++++++++++++++++++++++++++++++++++++
vw=λT Speed of propagation vw= wavelength x T time
vw=fλ Knowing frequency multiply times wavelength to get wave speed.
++++++++++++++++++++++++++++++++
Amplitude varies only as the energy applied varies. Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared or .707 of the peak of the waveform).

Typically, people think of a lava flow when they think of volcanoes. However, some eruptions are mostly ash and steam released into the atmosphere. This type of volcanic eruption is blamed for causing what is referred to as a "Little Ice Age" starting in the 13th century. The ash and steam blocked the sun's rays causing extreme cold and agricultural difficulty which lead to massive decreases in populations.
