A gene is the basic unit of heredity, responsible for the transmission of traits from parents to offspring.

The cell is the basic unit of life as it is the smallest structural and functional unit of an organism.

Cortisol is a steroid hormone that helps reduce inflammation and is involved in the stress response.

Deforestation leads to habitat loss, which significantly decreases biodiversity as many species lose their homes.

Deforestation increases carbon dioxide levels in the atmosphere as trees that absorb CO2 are removed.

Gibberellins promote seed germination by breaking dormancy and stimulating the growth of the embryo.

Magnesium deficiency leads to chlorosis, particularly in older leaves, as it is a key component of chlorophyll.

Parathyroid hormone (PTH) increases calcium levels in the blood by stimulating the release of calcium from bones and increasing calcium absorption in the intestines.

Photoperiod is crucial in determining the timing of flowering in many plants, influencing their reproductive cycle.

Plastic pollution leads to habitat destruction and bioaccumulation of toxins in marine organisms, severely impacting marine ecosystems.

In a dihybrid cross, the expected genotypic ratio in the F2 generation is 9:3:3:1.

The pistil is the female reproductive part of the flower, consisting of the ovary, style, and stigma.

A promoter is a DNA sequence that initiates transcription of a gene by providing a binding site for RNA polymerase.

A promoter is a DNA sequence that initiates transcription of a particular gene, allowing for gene expression.

Selectable markers are genes that confer resistance to antibiotics or other substances, allowing for the identification of cells that have successfully taken up the vector.

Cartilage provides support and flexibility in the body.

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in plants.

DNA polymerase is an enzyme that synthesizes new strands of DNA during replication.

Glucagon is a hormone produced by the pancreas that raises blood sugar levels by promoting the conversion of glycogen to glucose in the liver.

Lysosomes contain digestive enzymes that break down macromolecules, old cell parts, and microorganisms.

NADP+ acts as an electron carrier, becoming NADPH during the light-dependent reactions.

The function of nervous tissue is the transmission of impulses.

Oxytocin is a hormone that stimulates uterine contractions during childbirth and is also involved in social bonding.

Parathyroid hormone increases calcium levels in the blood by promoting the release of calcium from bones and increasing absorption in the intestines.

Petals serve to attract pollinators with their color and scent.

Phosphorus is crucial for energy transfer in plants, particularly in the form of ATP (adenosine triphosphate).

Ribosomes are the cellular structures responsible for protein synthesis.

Ribosomes are the cellular structures responsible for protein synthesis.

Sclerenchyma tissue provides support and protection to the plant due to its thick, lignified cell walls.

Stomata are small openings on leaves that facilitate gas exchange, allowing CO2 in and O2 out.
