The unusual strength of a glue makes it able to hold a heavy object, or load, as shown in the diagram below.
If the load exerts a strong downward force, the glue
A. destroys the force
B. exerts a stronger downward force
C. causes the load to accelerate upward
D. exerts an upward force that is equal to the downward force
Answers
Answer:
D
Explanation:
for every action, there is an equal and opposite reaction
If the load applies a significant downward force, the adhesive will apply an equivalent upward force. Thus, option D is correct.
What is role of upward and downward force?All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.
The acceleration that gravity gives to objects falling freely serves as a gauge of its strength.
All objects with mass, including our Earth, really bend and curve spacetime, which is what causes gravity to pull you toward the ground. What you experience as gravity is that curvature.
If the load exerts a strong downward force, the glue exerts an upward force that is equal to the downward force.
Therefore, exerts an upward force that is equal to the downward force.

Which statement is FALSE? A. Phototropism and geotropism are adaptations of plants that allow for survival. B. Tropism is the growth response of plants to their environment due to external stimuli. C. A plant's response to moonlight is phototropism while it's response to gravity is geotropism. D. A tropism that causes a plant to grow towards the stimulus is positive.
Answers
Answer:
A. Phototropism and geotropism are adaptations of plants that allow for survival.
Explanation:
Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus.
Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism.
Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"

Which structure pumps out excess water and wastes?
Answers
Answer:
The contractile vacuole pumps out excess water and wastes.
Cells have a particular organelle that pumps out excess water and other wastes from the cell. Contractile vacuole serves this purpose.
The protozoan cell contains an organelle or subcellular structure called the Contractile Vacuole. It is a spherical, transparent, translucent, pulsating single-cell organelle. Previously, it was referred to as a pulsatile or pulsating vacuole. It is encased in a unit membrane, floats in the cytoplasm, and is filled with watery fluid. It is a vacuole that constricts and expels water from the cell, as its name suggests. It frequently stretches and shrinks. While water is expelled from the contractile vacuole as it expands, the contractile vacuole contracts, causing water to collect inside the organelle. The contractile vacuole is the protozoan unicellular organism's kidney. It shows the rhythmic systolic and diastolic movements.
Therefore, Contractile vacuole pumps out excess water & wastes.

1. A worker uses a board that is 4 m long to pry up a boulder. A small rock is used for a
fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the
I
board.
Answers
Answer:
7
Explanation:
Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.
Here the boulder is [tex]0.5\ \text{m}[/tex] from the fulcrum and the mass at the other end of the lever is [tex]4-0.5=3.5\ \text{m}[/tex] from the fulcrum.
So, mechanical advantage is given by
[tex]MA=\dfrac{3.5}{0.5}\\\Rightarrow MA=7[/tex]
So, mechanical advantage of the board is 7.

The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.

What is Evolution?According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognizable differences are the result of changes made by subsequent generations.
More than 2 million species of organisms already in existence have been recognized and documented; many more are still undiscovered, with estimates ranging from 10 million to 30 million.
The amazing variability in size, form, and mode of existence, from tiny bacteria with a diameter of less than a millionth of a millimeter to majestic sequoias with a height of 100 meters, is as astonishing as the figures.
Therefore, negative adaptations will become more common in a population.
