Explanation

• Tertiary consumers are animals that eat primary and secondary consumers.
• They are typically apex predators that have no natural predators in the wild and are at the top of their food chain.
• Examples of tertiary consumers include lions, sharks, bears, and humans.

Explanation

Iodine is involved in the formation of thyroid hormones (triiodothyronine (T3) and thyroxine (T4)) produced by the thyroid gland.

Iodine is essential for the production of thyroid hormones, which are necessary for:

• Energy production
• Regulation of metabolic rate
• Growth and development
• Nervous system function

Explanation

• The air you breathe in enters the lungs through the windpipe (trachea).
• The trachea is a tube that connects the throat (pharynx) to the lungs, allowing air to pass through during breathing.

Explanation

• Humans have 20 primary teeth (also known as deciduous or baby teeth).
• 32 permanent teeth (also known as adult teeth).

Explanation

Hookworm infection is the most likely to lead to anemic heart disease

It is caused by blood loss at the site of the intestinal attachment of the adult worms.

Hookworms feed on blood in your intestines.

An untreated, severe infection results in blood loss.

Blood loss can lead to anemia and protein deficiency

Explanation

Facial nerve paralysis typically cannot be directly detected on a CT (computed tomography) scan.

A CT scan can help identify potential causes of facial nerve paralysis, such as tumors 

Explanation

The most common cause of neonatal deaths in developing countries is "birth asphyxia."

Hypoxia is a newborn condition caused by insufficient oxygen before, during, or after birth.

It can result from various factors such as:

• prolonged labor
• placental complications
• umbilical cord problems
• maternal health issues
  

Explanation

Calcium is considered a micronutrient because it is required in small quantities.

It plays a crucial role in various physiological functions, including:

• bone and teeth health
• muscle function
• nerve transmission
• blood clotting.

They support various metabolic functions.

It includes:

• vitamins (such as vitamin C, vitamin D, and vitamin B12) 
• minerals (such as iron, zinc, calcium, and magnesium).

Additional information:

Macronutrients needed in larger quantities, including:

• carbohydrates
• proteins
• fats

It provides energy and serves as a building block for bodily tissues.

Explanation

• A Barr body is a densely staining body found in the interphase nuclei of somatic cells of female mammals, including humans.
• It is a condensed, inactivated X chromosome, which is one of the two X chromosomes present in the nuclei of female cells.
• The Barr body is a result of X-chromosome inactivation, a process that occurs in female mammals to avoid a doubling of gene expression.

Explanation

• Prokaryotic cell membranes, such as those found in bacteria, are composed of a thin layer of phospholipids, primarily phosphatidylethanolamine and phosphatidylglycerol, and embedded proteins.
• The phospholipid bilayer forms a semi-permeable membrane that regulates the entry and exit of materials, while the proteins perform various functions such as transport, enzymatic activity, and cell signaling.
