Answer:
C) Platelets
Explanation:
Hemophilia is caused by a lack of clotting factors. Because platelets (or lack thereof) are what is responsible for how the blood clots, it can be reasonably inferred that the answer is C.
(Platelets secrete procoagualants, which are clotting factors. If there is a genetic issue with how these clotting factors work, then the platelets will not be useful.)
Answer:
Yes
Explanation:
Indeed, <u>the best solution for maintaining biodiversity is to conserve the biodiversity of every ecosystem, since all ecosystems have benefits to humans and the earth</u>.
Ecosystems might vary in the kind of services they render to the planet or humans in general. For example, the forest ecosystems supply humans with the necessary timber and wood for construction purposes and sequestrate carbon/produce oxygen from and to the environment respectively. Thus, the forest ecosystem plays a huge role in maintaining the air quality of the planet in addition to several other services.
The variation in the services the different ecosystems render to the human population and the planet necessitates that the biodiversity of every one of them be conserved. Prioritizing the conservation of one over the other will result in losing some of the services provided as a result of loss of biodiversity.
