Weak push
The force used on your arm when you walk a dog on a leash and it tries to
chase something is known as Strong pull.
Strong pull is defined a physical force which is usually aggressive or
coercive and it involves the movement in a particular direction due to
different factors or reasons.

Option (a) 77
(b) 87
(c) 92
(d) 95
(e) 102
Plz answer
Answer:
its e (102)
Explanation:
so, 120*15/100
Cancelling the zeros!
so,
12*15/10
= 6*15/5
=6*3/1
First we have to find 15% of 120
=6*3
=18
So, 15% of 120 is 18
now decreasing it from 120
120-18
=102

Prokaryotic and eukaryotic cells have several differences. Which statement below is not one of those
differences?
Prokaryotic cells are found in the domains Eubacteria and Archaea.
Eukaryotic cells have organelles for processes like respiration or photosynthesis.
Prokaryotic cells cannot make their own proteins.
Eukaryotic cells are generally ten times larger than prokaryotic cells.
prokaryotic cells cannot make their own proteins, the statement is false. Thus the option C is correct.
What are the distinguishable features of prokaryotes and eukaryotes ?Prokaryotic cell are unicellular as it is made up of single cell and the size ranges from 0.2 μm – 2.0 μm while eukaryotic cell are multi-cellular, the size ranges from 10 μm – 100 μm in diameter.
cell wall is present in prokaryotes which involve in providing protection of the cell where as only in plant cell wall is present; True Nucleus is absent in prokaryotes instead of nucleus, nucleoid is present which carry genetic material while in eukaryotes true nucleus is present.
The Ribosomes are Smaller in size and 70s type in prokaryotic cell where as the ribosome is larger in size with 80s type in eukaryotic cell larger in size and linear shaped ribosomes are present.
All the metabolic and physiological activities occur in a single cell of prokaryotes where as the metabolic and physiological activities occur in different organelle.
Thus the option C is correct.

Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
v1 = 0.25 m / t1, and
v2 = 0.25 m / (t2 – t1)
where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E.
What is the first velocity of the car with two washers at the 0.25 meter mark?
m/s
What is the second velocity of the car with two washers at the 0.50 meter mark?
m/s
(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)

A) nucleus - provides carbohydrates for fermentation
B) Chloroplast - serves ae the site for photosynthesis
C) centriole - synthesizes digestive enzymes
D) lysosome - packages cellular products
Answer:
B) Chloroplast - serves ae the site for photosynthesis
The function of chloroplast is to synthesis food.
The organelle that is correctly paired with its function is the chloroplast, which serves as the site for photosynthesis and is present in Option B as the chloroplast is the site of food synthesis.
What is the significance of chloroplasts in plants?Chloroplasts are cell organelles that are found in the cells of green plants, algae, and some other photosynthetic organisms and are the site of photosynthesis, which is the process by which plants convert light energy into chemical energy in the form of glucose, and it absorbs light energy, which is then used to convert carbon dioxide and water into glucose through a light reaction and the Calvin cycle, and the animals and plants get their food from it.
Hence, the organelle that is correctly paired with its function is the chloroplast, which serves as the site for photosynthesis and is present in Option B as the chloroplast is the site of food synthesis.
