The answer
is arthropods have had more time to co-evolve with land plants than have
vertebrates. Analysis of genes shows that their sequences are quite similar,
and these sequences differ from those of the lophotrochozoans and
deuterostomes. Between the annelids and
arthropods will probably be viewed, in retrospect, as an instance of an
evolutionary relationship that modern scientists had ʺset in stone, ʺ now
having crumbled.
Answer: B) Black bears, deer, and squirrels would undergo a mass extinction, so the forest’s biodiversity would decrease.
Limiting factor is a factor which limit the growth, distribution and abundance of population of one or more species in an ecosystem. A limiting factor can be natural or man-made. Natural limiting factor includes resources (food, shelter and water), abundance in predator population, natural disasters like landslide and earthquakes. Man-made limiting factors include deforestation, forest fires and nuclear explosions.
Here, oak trees can be considered as limiting factor. Oak trees are source of food resource in temperate deciduous forest. Cutting down of these trees will affect the populations of animals residing in the forest. As, populations of beer, black deer, and squirrels all rely on the acorns obtain from oak trees, cutting down of trees will result in mass extinction of black bears, deer, and squirrels. Hence, the diversity of animals in forest would decrease.
Your answer would be M. Deciduous forest. Hope this helped :]
Answer:
The correct answer is b) placing medication drops in nose, eyes, or ears.
Explanation:
Instill refers to the action of pouring or introducing a liquid drop by drop on a mucosal surface or inside a canal or organic cavity, for therapeutic purposes. The most used instillations are: conjunctival, nasal, paranasal, atrial, laryngeal, tracheal, bronchial, bladder and urethral. The instillation can be carried out with the help of a simple common dropper or with an instrument called an instillator, which consists of a probe with a widened end and a syringe with a screw plunger; by activating the screw, the medicine is introduced drop by drop.
