Explanation

Iron is an essential mineral found in various foods, including:

• Liver
• Dark green vegetables (spinach, kale, broccoli)
• Red meat
• Flour (enriched)
• Egg yolk
• Dried fruit ( apricots, prunes, raisins)
• Nuts (pistachios, almonds)
• Dried beans (lentils, chickpeas)
• Peas
• Poultry (chicken, turkey)
• Fish (tuna, salmon)

Iron is crucial for:

• Oxygen transport in the blood
• Healthy red blood cells
• Immune function
• Brain function
• Physical performance

Explanation

Heredity is the property that passes similar characteristics from parents to their offspring, making a human baby similar to human beings.

Explanation

• Canines, also known as cuspids, are pointed teeth used for ripping and tearing food.
• They are located on either side of the incisors.
• It are designed for piercing and tearing flesh, making them ideal for eating meat and other tough foods.

Explanation

To improve the health of nations through initiatives like "The Sustainable Development Goals" (SDGs) is HIMIS

HIMIS stands for Health Information Management Information System.

HIMIS contributes to the achievement of various health-related SDGs, such as:

• reducing maternal and child mortality,
• combating infectious diseases,
• promoting universal health coverage.

Additional information:

While

women's education, involvement of men in reproductive health (RH), and health system research are also important factors in improving health outcomes,

They are not as directly tied to the implementation and monitoring of health initiatives like HIMIS.

However, they may indirectly contribute to the achievement of health-related SDGs 

Explanation

• When cells become specialized, they undergo a process called differentiation, where they develop specific structures and functions to perform specific roles in the body.
• During differentiation, cells transcribe different genes, meaning they express different sets of genes that are specific to their specialized function.
• This leads to the production of different proteins and molecules that enable the cell to perform its unique function.

Explanation

• "In plants, the cell signaling occurs through phytohormones": True. Phytohormones, such as auxins, gibberellins, cytokinins, ethylene, and abscisic acid, play a crucial role in plant cell signaling, regulating various physiological processes like growth, development, and responses to environmental stimuli.
• "Cell signaling is used to study the context of human diseases": True. Cell signaling is indeed used to understand the underlying mechanisms of various human diseases, including cancer, diabetes, neurological disorders, and many others.
• "Cell signaling is used to study the signaling between cells of an organism": True. Cell signaling is essential for understanding how cells communicate with each other to coordinate various physiological processes within an organism, including development, homeostasis, and responses to stimuli.

So, all three statements are true, making "All of the above" the correct answer!

Explanation

In tracheophytes (vascular plants), the male gametophyte develops from a microspore, forming a microgametophyte (pollen grain).

The microgametophyte produces male gametes (sperm cells) for fertilization.

Explanation

A holoenzyme is the complete, active enzyme, formed when an apoenzyme (protein part) binds with its cofactor or coenzyme.

It consists of a polypeptide chain plus non-protein component, making it catalytically active.

Explanation

The margin of the prothallus (the gametophyte stage of Adiantum) is typically one cell thick.

This thin edge helps in gas exchange and absorption, important for the fern’s reproduction and development.
