Answer:
Most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone.
Answer:
According to toppr
Receptors are specific proteins located on target tissues to which specific hormones bind to produce their effect.
Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex. Formation of Hormone-Receptor complex leads to certain biochemical changes in the target tissue.
Hence Receptor site responds to a hormone.
So, the correct answer is 'Receptor'.

Explain the movement of ribs during inhalation and exhalation.
Answer:
Inspiration (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).
Explanation:
Explanation:
During normal breathing, contraction of the major inspiratory muscle, the diaphragm, produces both rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative relative to atmosphere.

Where do electrons go after they leave chlorophyll?
Answer:
They leave and find somewhere else to replace the previous electron that had left just like it did and repeats the same process over and over again.
Explanation:
This is what i found on the internet to further explain my response, "The electron lost from the chlorophyll a special pair is replenished by splitting water. The passing of the electron in the first part of the electron transport chain causes protons to be pumped from the stroma to the thylakoid lumen." "When light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule. ... The excited electrons leave chlorophyll to participate in further reactions, leaving the chlorophyll “at a loss”; eventually they must be replaced."

Which of the following explains how fault is formed?
a. Earthquakes shake the rocks to slide horizontally, vertically, or sideward.
b. Gravity pulls on the crust to slide up, down or past each other.
c. Different forces pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
d. Same force pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
Answer:
a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Explanation:
The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Reason -
A fault is a fracture or zone of fractures between two blocks of rock.
Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.
During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.
The fault surface can be horizontal or vertical or some arbitrary angle in between.
Low frequency waves:
A. have high amplitudes.
B. Have long wavelengths.
C. Travel at high speeds.
D. Have short wavelengths.
Answer:
Its A
Explanation:
Its A =Have high amplitudes
Low-frequency waves have long wavelengths. Therefore, option B is correct.
What are waves?
Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.
Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.
Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.

Why might it be hard to restore a wildlife population using custodial management?
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.
What is the process of evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations. According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.These characteristics are easily trasffered from one generation to other generation.

Which of the following is not a stage in hurricane formation?
A)
Thunderstorms in a low-pressure area combined with the Earth’s rotation cause the storm’s initial rotation.
B)
Pollution in the atmosphere raises the temperature of the air, creating a depression.
C)
Warm, moist air rises from the sea and increases the storm’s energy.
D)
As water from the sea turns into water vapor, latent heat enters the storm, causing the storm’s energy to increase.
E)
As condensation (rain) occurs, latent heat is released, which warms the air and makes it lighter, causing the hurricane to increase in strength and intensity.
Answer:
B
Explanation:
Because if that was the case we would have hurricanes everyday

why does the sodium potassium pump require ATP?
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

Read the paragraph from the section "Pea Plants And The Punnett Square."
A pea plant could have one copy of the height gene that coded for "tall" and one copy of the height gene that coded for
"short." The tall allele is "dominant," and this means that it can mask the other allele. The short allele is called
"recessive." The allele combination of tall-short would result in a tall plant since the tall allele is dominant.
Which option is the BEST definition of the word "mask" as used in the paragraph above?
