Answer:
The magnetic field due to a solenoid is given as : where, is the permeability of the medium. n is the number of turns or loops in the coil. I is the current flowing in the solenoid.
The magnetic field due to a solenoid can be increased by increasing the number of turns, current and placing an iron core inside the solenoid.
So, the correct option are:
(1) using more wire loops
(2) using a larger current
Hence, the correct options are (a) and (c).

Answer:
The advise I will offer the next scientist about how the laboratorycan beimproved include the following
Calibration of instruments: Instruments which are used in the laboratory should be calibrated so as to reduce errors and inaccuracy during experiments.
Proper labeling of Samples : This helps to give the scientists an idea of where to find samples and to prevent making mistakes in picking the wrong one. This helps to save time and resources in the lab.
Adequate cleaning and waste disposal: Cleaning of the lab and disposal of the wastes helps to eliminate contamination of samples.

Explanation:
The eggs of a frog hatch into tadpoles, which look like little fish. After a few days, tadpoles develop legs and arms and grow into young frogs with tails. In the next few days, they grow into an adult frog with no tail. The process of growing from a tadpole to an adult frog is called metamorphosis
