3. Seperation
4. Opposition
Explanation:
I had this question on my test last week
Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.
Study of fossils has led to important new understanding about how life evolved on earth and about diseases, both ancient and modern. Fossils also help us understand past climates, including ice ages and periods that were warmer than our present climate. Knowledge from the study of fossils is helping geoscientists understand global warming and its effects. By studying the catastrophic extinction of the dinosaurs and many other life forms at the end of the Cretaceous Period, geoscientists have gained insight into the evolutionary implications of impacts by extraterrestrial objects. Investigating the physical and chemical characteristics of fossil organisms that lived during times of drastic climatic change helps us understand the implications of the changes we are making in our own environment. <span>Information about Earth history, practical help in finding energy resources, and information that helps us anticipate the effects of possible environmental changes are not the only benefits derived from fossils. hope this helps :)</span>
The correct answer is ocean
The water that is naturally occurring in the nature expect the seawater, water in the ocean, backish water is freshwater.
The least likely fresh water reservoir is ocean water, which is salty in nature. This has high concentration of dissolved salts in it.
This water cannot be used as potable water employed for the commercial and drinking purposes.
The True statements are.
Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.
The best equipped organism survive which is known as the survival of the fittest.
Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.
The false statement is Organism of the same species are equipped with the same survival skills.
The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.
