Ascientist makes a claim that two hominid species have a common evolutionary ancestor. what 3 processes must happen to ensure this claim can be considered valid?

The correct answer is option D, that is, scientific evidence must be found, verified, and accepted by the scientific community.

A scientific claim is one, which totally relies on systematic observation and proof. It is created to be far more reliable than any other kind of claim one could make. However, unfortunately, not every scientific claim is not true. Some of the findings are precise and reliable, while others exhibit flaws.

There is a difficulty in finding out the difference between them. Although to consider the claim put forward valid, there is a need to find out the scientific evidence, then verification has to be done, and then finally it has to get accepted by the scientific community.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
