answer
Height at which kiwi reach=1.2m
Solution
In this question we have given
mass of apple,
mass of kiwi,
height from which apple is dropped,
Let the height at which kiwi reached is
here,
We will apply law of conservation of energy
it means,
potential energy of kiwi= potential energy of apple
......(1)
here g is gravitational acceleration
put values of and in equation 1
therefore, Height at which kiwi reach=1.2m
Answer: The lac Y and lac Z genes are turned off when lactose is present. Is a false statement about E coli and the lac operon. Therefore the correct option is A.
Explanation:
Escherichia coli is an enteric bacteria that makes use of lactose operon (or lac operon) for its lactose metabolism. The lac operon is made up of three genes which includes lacZ, lacY and Lac A. These genes are expressed only when lactose is present and glucose is absent. Also the lac repressor acts as a lactose sensor while the catabolite activation protein (CAP) acts as a glucose sensor. They help in turning on and off the genes with respect to lactose and glucose levels.
The lac Y and lac Z genes are turned off (not expressed) when glucose is present and lactose absent, but are expressed when glucose is absent and lactose present. Therefore option A is a false statement.
Answer:
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
Explanation:
The new fuse will not blow up when a higher current is flowing and the circuit wont be broken and high current can heat up the object and cause a fire boom
Answer:
Here,
Initial velocity(u)=0 m/s
acceleration(a)=1.5m/s
time(t)=0.5s
Now,
distance covered(s)=ut+(1/2)at^2
=0*0.5+(1/2)*1.5*0.5*0.5
=0+(1/2)*0.375
=0+0.1875
=0.1875(nearly 0.19)
Hence,0.19 is correct answer.
