Explanation

• A hypothesis is a proposed explanation for a phenomenon or a problem that can be tested through scientific investigation.
• It is a educated guess that provides a possible answer to a question or problem.
• A hypothesis must be testable and falsifiable, meaning that it can be proven or disproven through experimentation or data collection.

Explanation

• Quantitative observation involves the use of instruments, tools, or equipment to measure and collect numerical data about the world.
• This approach focuses on quantifying properties, such as length, mass, temperature, or time, to describe phenomena accurately.

Examples of equipment used in quantitative observation include:

• Thermometers
• Spectrophotometers
• Microscopes
• Telescopes
• Stopwatches
• Balances

Explanation

The two unpaired facial bones are the mandible and the vomer.

Mandible:

The mandible, commonly known as the jawbone, is the largest and strongest bone of the face.

It forms the lower jaw and holds the lower teeth in place.

It is the only movable bone of the skull.

Vomer:

The vomer is a thin, flat bone that forms part of the nasal septum, which divides the nasal cavity into left and right sides.

It is located inferiorly within the nasal cavity.

Explanation

Beriberi is not a lipid storage disease.

This is a nutritional deficiency disease caused by a lack of vitamin B1 (thiamine).

It affects the cardiovascular and nervous systems

Explanation

In a renal transplant, regulating protein intake is crucial to minimize strain on the transplanted kidney.

Excessive protein consumption can lead to complications such as proteinuria and kidney damage.

Explanation

Fibrin is actively formed on the surface of activated platelets.

Explanation

One parent (at least) must be heterozygous.

Blood group genetics:

Blood type is determined by three genes, A, B, and O. A and B are dominant over O, meaning if someone inherits even one A or B gene, they will have blood type A or B, respectively.

If they inherit two O genes, they will have blood type O. 

Scenario:

If one brother has blood type A (could be AA or AO genotype) and the other has blood type O (OO genotype), they must have inherited an O gene from each parent.

This means that at least one parent must be heterozygous (AO) for the A gene to produce an A blood type child and an O blood type child.

Explanation

The telencephalon is the part of the developing brain that eventually forms the cerebral hemispheres.

The term "cerebral hemispheres" is synonymous with the telencephalon. 

Explanation

If a codon consisted of only two nucleotides, there would be 16 possible codons. 

Since there are four possible nucleotides (A, C, G, and T), each position in a two-nucleotide codon could be filled by any of these nucleotides.

Therefore, to calculate the total number of possible codons,

We multiply the number of possibilities for the first position by the number of possibilities for the second position:

4 nucleotides * 4 nucleotides = 16 possible codons.
