Explanation:
1. the similarity between biosphere and ecosystem is that they both have organisms that depend on each other and the difference is that biosphere uses every single organism while ecosystem only uses organisms that are inside of the ecosystem. 2. the similarity between theory and hypotheses is that they are both something that have to be scientifically proven and the difference is a theory relies on evidence and a hypothesis relies on a possibility. 3. a similarity between independent variable and constant is that they both change at the same time and the difference is that an independent variable is controlled or changed by the scientist while a controlled variable is one that they want to remain the same.
False ⇒ Our cells (human cells) contain DNA!
Answer:
<u>Option-(B):</u>The neutrophil forms lamellipodial extensions.
Explanation:
<u>Lamellipodial extensions:</u>
The lamellipodal extensions is a type of cytoskeletal protein actin projection. And is the effect of expressing a dominant active form of the small GTPase Rac1 in a human neutrophil.
Option c I hope it helps:) this came for me too
The correct answer is - predator species in a community.
In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.
The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.
If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.
