Biology
1 answer:
pochemuha2 years ago
4 0

Answer:

Explanation: Although cellular respiration has multiple parts, the basic chemical equation is:

Answer: Oxygen

Explanation: Oxygen + Glucose (sugar) = Carbon Dioxide + Water + Energy (ATP)

This equation is often broken into two parts, the reactants and the products. Reactants are the molecules that begin cellular respiration, in this case that would be oxygen and glucose. Products are what forms during cellular respiration. Here, the products are carbon dioxide, water, and energy. As the focus of this lesson is on the reactants of cellular respiration, oxygen and glucose, let's take a look at those.

Reactants--

The first reactant in the equation for cellular respiration is oxygen. Most people are familiar with oxygen since it's the primary gas needed for sustaining our lives. We obtain oxygen by simply breathing. Oxygen is highly reactive and therefore perfectly suited for driving chemical reactions such as cellular respiration. However, people may be less familiar with the second reactant in our respiration equation: glucose.

An example of an epigenetic change is
Oksana_A [137]

Answer:

The correct answer is option d.

Explanation:

An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.  

One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.  

In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.

Put the fats in order from the one that contains the greatest percentage of saturated fatty acids (1) to the one that contains t
olganol [36]

Answer:coconut oil, butter, palm oil, olive oil, canola oil.

Explanation: .

A saturated fat one whose fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules which are glycerol and fatty acids. Fats are made of long chains of carbon (C) atoms while some carbon atoms are linked by single bonds (-C-C-) bonds others are linked by double bonds (-C=C-). These Double bonds will react with hydrogen to form single bonds causing them to be SATURATED, because when the second bond is broken, each half of the bond is then saturated with a hydrogen atom.

In terms of saturated fats acids composition by percentage according to ChartsBin statistics collector team 2011, Fat Composition in different Cooking Oils, ChartsBin.com, palm oil is 14.192, coconut oil is 91.92 canola is 7.46,palm oil 51.57, butter 65%-68%.Here you can see that the order of saturated fats from the highest gives- Coconut,butter, palm oil,olive oil and Canola as the last
