first and third one
Explanation:
animals need the oxygen they make. and animals eat the plants. if an animal doesnt eat plants it eats somthing that does. sorry for the typos.
<u>Answer:</u>
<em>Brain organoids </em>is the anatomical resemblance of the mammal brain. It is formed by culturing the stem cells in three dimensional rotational bioreactors. The main difference between the <em>organoids and real brain</em> is the real brain has the connection to outside world to mature in good manner.
The brain organoids are used to apply the <em>genuine experimentation</em> on the brain disorders. It helps in directly studying the tissues and neurons to study disease<em> present in any patients. </em>
Saliva contains the enzyme, salivary amylase. This enzyme breaks the <u>bonds between the monomeric sugar units of disaccharides, oligosaccharides, and starches</u>.
The salivary amylase breaks down amylose and amylopectin into smaller chains of glucose, called dextrins and maltose.
Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb.
For eg- Amylase is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates into easier to absorb simple sugars. Salivary amylase is the first step in the chemical digestion of food.

Explanation:
First of all, energy conservation plays an important role in saving non-renewable energy resources. Furthermore, non-renewable energy sources take many centuries to regenerate. Moreover, humans consume energy at a faster rate than it can be produced. Therefore, energy conservation would lead to the preservation of these precious non-renewable sources of energy.
Energy conservation will reduce the expenses related to fossil fuels. Fossil fuels are very expensive to mine. Therefore, consumers are required to pay higher prices for goods and services. Energy conservation would certainly reduce the amount of fossil fuel being mined. This, in turn, would reduce the costs of consumers.
Consequently, energy conservation would strengthen the economy as consumers will have more disposable income to spend on goods and services.
Energy conservation is good for scientific research. This is because; energy conservation gives researchers plenty of time to conduct researches.
Therefore, these researchers will have more time to come up with various energy solutions and alternatives. Humans must ensure to have fossil fuels as long as possible. This would give me enough time to finding practical solutions.
