سب سے بڑی اکائی جس کے اندر جین کا بہاؤ آسانی سے ہو سکتا ہے ______ ہے؟
A. Population
B. Species
C. Genus
D. None of these
Check answer and explanation
Answer: Population
Explanation Gene flow readily occurs within a population , as individuals within the same population can interbreed freely. Populations are smaller units within species where genetic exchange is most active.
Explanation Hot spots are regions with exceptionally high levels of species richness and endemism. They are crucial for conservation as they host unique species found nowhere else.
Explanation Francis Balfour is considered the Father of Modern Embryology. Due to his contributions to the study of vertebrate development. He significantly advanced knowledge of embryonic development and comparative embryology.
Explanation The evidence for chordate ancestry in echinoderms mainly relies on Deuterostome embryonic development Both echinoderms and chordat es are deuterostomes . In deuterostomes, the blastopore forms the anus first . They show similar patterns of early embryonic development . This developmental similarity indicates a common evolutionary ancestry .
نمکیات کی وسیع رواداری کے ساتھ ایک پرجاتی کو کیا کہا جاتا ہے؟
A. Stenothermal
B. Stenohaline
C. None of these
D. Euryhaline
Check answer and explanation
Answer: Euryhaline
Explanation Euryhaline species can tolerate a wide range of salinities. It enabling them to survive in varying aquatic environments. Examples include certain fish like salmon that migrate between freshwater and seawater.
فوسل شواہد سے پتہ چلتا ہے کہ جغرافیائی وقت کے ساتھ گھوڑوں کے سائز میں بتدریج اضافہ ہوا ہے۔ مندرجہ ذیل میں سے کون سی اصطلاح اس کی بہترین وضاحت کرتی ہے؟
A. Artificial selection
B. Directional selection
C. None of these
D. Stabilizing selection
Check answer and explanation
Answer: Directional selection
Explanation Directional selection occurs when one extreme phenotype is favored. It leading to a shift in the population's traits over time. The increase in horse size over geologic time is an example of this type of selection.
Explanation Apiculture is the practice of rearing honeybees for honey and wax production . Helps in pollination and increasing crop yields . Honey, beeswax, and propolis are valuable products from apiculture . Additional information : Sericulture → Rearing of silk worms. Silviculture → Cultivation of trees and forests.

Explanation The destruction of wildlife is a multifaceted problem, and the answer is All of these, as deforestation, overfishing, and climate change are all significant drivers of wildlife decline.
Explanation The moisture content of 16% is allowed in prepared pellets for optimal storage and quality. This moisture level helps prevent spoilage while maintaining pellet integrity.
Explanation Lamarck proposed that organisms develop traits during their lifetime in response to their environment and pass them on to offspring. This theory, called Lamarckism , was later disproven by modern genetics .
