Explanation

• A parasite is an organism that feeds and lives in or on part of another organism (host), often causing harm to the host.
• Examples of parasites include tapeworms, fleas, and lice.

Explanation

The diagnostic test typically used for rheumatic fever is ASO (Anti-streptolysin O) titer.

Rheumatic fever is an autoimmune inflammatory disease

That can develop after a group A streptococcal infection, such as strep throat. 

The ASO titer measures the antibodies produced in response to a recent streptococcal infection.

Elevated ASO titers indicate recent streptococcal infection and are a key diagnostic marker for rheumatic fever.

Explanation

 The term for similarity in characteristics resulting from common ancestry is Homology. 

Homology refers to the shared features between organisms that are derived from a common ancestor. 

Explanation

 If both parents have AB blood groups (genotype IAIB), their offspring can have blood types A, B, or AB, but not O.

This is because blood group O requires two recessive "i" alleles, which are not present in either parent's genotype. 

Explanation

The sun is the ultimate source of energy for our planet, providing energy through solar radiation.

This energy is then converted into various forms, such as:

• Thermal energy (heat)
• Kinetic energy (wind, water currents)
• Electrical energy (generated from solar panels)
• Chemical energy (fossil fuels, biomass)
• Biological energy (food chains, ecosystems)

Explanation

Fungi are achlorophyllous, meaning they lack chlorophyll and are unable to photosynthesize.

Instead, they are absorptive living organisms, obtaining their nutrients by breaking down and absorbing organic matter from their surroundings.

Explanation

Homologous chromosomes are pairs of chromosomes that are similar in shape, size, and genetic content, and have the same position of the centromere.

They contain the same genes in the same order, but may have different variations of those genes (alleles).

Explanation

The female gametes (eggs) are fertilized in the fallopian tube, which is also known as the oviduct.

The fallopian tube is the narrow tube that connects the ovary to the uterus, and it's where the sperm fertilizes the egg.

Explanation

Kwashiorkor is a condition caused by a deficiency of dietary protein, leading to an imbalance in the gastro-intestinal system. It is characterized by:

• Edema (swelling) in the legs, feet, and face
• Diarrhea
• Weight loss
• Hair loss
• Skin lesions
• Impaired immune function

Explanation

• The dark reaction, also known as the Calvin cycle.
• It is a light-independent reaction that occurs in the stroma of the chloroplast.
• This process uses the energy from ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
