Explanation

nsulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

Its deficiency leads to prolonged bleeding or poor blood clotting.

Explanation

Microscopes are instruments designed to produce magnified visual images of small objects or samples.

It allowing us to see details that are not visible to the naked eye.

Explanation

Homologous structures are those that have different functions (physiology) but share similar internal architecture or morphology, indicating a common evolutionary origin.

Examples include:

• Forelimbs of vertebrates (e.g., human arms, bird wings, whale flippers)
• Pelvic bones of different mammals

Explanation

Biotechnology in industry refers to the use of biological systems, living organisms, or derivatives thereof, to develop new products and processes on a large scale.

Explanation

Air pollution refers to the presence of harmful substances in the air, including solid waste and excess gases, which can harm human health and the environment.

Examples include particulate matter, carbon monoxide, and volatile organic compounds, which can lead to respiratory problems and other health issues.

Explanation

The female gametophyte of angiospermic plants is the embryo sac.

It ilso known as the megagametophyte.

It is the haploid (containing one set of chromosomes) structure within the ovule that contains the egg cell and is responsible for fertilization.

Explanation

Homeostasis is the set of metabolic reactions that maintain the internal environment of an organism, regulating factors.

Such as temperature, pH, blood sugar levels, and blood pressure.

Explanation

• The light-dependent reactions (also known as the Hill reaction) occur in the thylakoid membranes of the chloroplast.
• Thylakoids are specialized membranous structures found in chloroplasts, where light energy is absorbed and converted into ATP and NADPH.
