Explanation

• The correct sequence of biological method is: Hypothesis → Reasoning → Theory → Law

This sequence represents the scientific method in biology, which involves:

• Formulating a hypothesis (a educated guess) to explain a phenomenon
• Using reasoning and logic to develop predictions and test the hypothesis
• Developing a theory (a well-substantiated explanation) based on the results of experiments and observations
• Establishing a law (a universal principle) that describes the phenomenon

Explanation

• Fisheries refer to the industry or practice of catching, breeding, and managing fish and other aquatic organisms.
• Increased quantity and quality of fish production is a result of improvements in fisheries management, aquaculture (fish farming), and fishing technologies.

Explanation

Earth's magnetic field always has a horizontal component except at  At 60*latitude 

At magnetic poles, the angle of dip is  $90^o$ . Hence the horizontal  component 

 $B_H=Bcos\theta =0$ 

Explanation

• A substance is a piece of matter in pure form, with a specific composition and properties.
• It can be either an element or a compound.

Explanation

• Cat and Dog is a secondary consumer.
• Because it eats primary consumers (herbivores).
• Like mice, birds, and rabbits.

Explanation

Aluminum (Al) is a metal that can easily lose electrons to form ions, making it a reducing agent.

As a reducing agent, aluminum can donate electrons to other substances, causing them to be reduced.

Explanation

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

Explanation

• In a parallel circuit, if one bulb blows, the other bulb will remain the same.
• This is because each bulb in a parallel circuit has its own independent path to the power source.
• The failure of one bulb does not affect the current flowing through the other bulb's path.

Explanation

Lenses form images through Refraction.

It bends light to focus it on a point, creating an image.

Explanation

A solar eclipse occurs when the Moon passes between Earth and the Sun,

thereby obscuring the view of the Sun from a small part of the Earth, totally or partially.
