Which does moss use to attach itself to places?
-
Tendons
-
Roots
-
Hairs
-
Rhizoids
Correct Answer
A. RhizoidsExplanation
Moss uses rhizoids to attach itself to places. Rhizoids are thread-like structures that grow from the base of the moss and anchor it to surfaces such as soil, rocks, or tree bark. These structures not only provide stability to the moss but also absorb water and nutrients from the environment. Unlike roots, which are found in higher plants, rhizoids do not have a vascular system and do not play a role in absorbing water and nutrients for the entire plant.Rate this question:

What vascular plants do not have seed-bearing flowers or fruits?
-
Angiosperms
-
Ending Sperms
-
Vascularsperms
-
Gymnosperms
Correct Answer
A. GymnospermsExplanation
Gymnosperms are vascular plants that do not have seed-bearing flowers or fruits. Instead, they produce naked seeds that are typically found in cones or on the surface of scales. Examples of gymnosperms include conifers, cycads, and ginkgoes. These plants have evolved a different reproductive strategy compared to angiosperms, which have flowers and fruits to protect and disperse their seeds. Gymnosperms rely on wind or other external factors for pollination and seed dispersal.Rate this question:

The first vaccine targeted which disease?
-
Diphtheria
-
Polio
-
Smallpox
-
Chicken Pox
Correct Answer
A. SmallpoxExplanation
Smallpox was the first disease to be targeted by a vaccine. The smallpox vaccine was developed by Edward Jenner in the late 18th century and was the first successful vaccine to be widely used. Jenner observed that milkmaids who had contracted cowpox, a less severe disease, seemed to be immune to smallpox. He then tested his theory by inoculating a boy with cowpox and later exposing him to smallpox, which resulted in the boy remaining unaffected. This breakthrough led to the development of the smallpox vaccine, which played a crucial role in eradicating the disease globally.Rate this question:

Which scientist disproved the Spontaneous Generation Theory?
-
Francisco Redi
-
Galileo
-
Louis Pasteur
-
Albert Einstein
Correct Answer
A. Francisco RediExplanation
Francisco Redi is the correct answer because he conducted experiments in the 17th century that disproved the Spontaneous Generation Theory. This theory proposed that living organisms could arise spontaneously from non-living matter. Redi's experiments involved placing meat in jars, some covered and some uncovered, to observe if maggots would spontaneously generate. He found that maggots only appeared in the uncovered jars, where flies could lay their eggs. This experiment provided evidence against the idea of spontaneous generation and supported the concept of biogenesis, which states that living organisms can only arise from other living organisms.Rate this question:
