Answer:
Location of the Heart. The human heart is located within the thoracic cavity, medially between the lungs in the space known as the mediastinum.
Answer:
b. reducing molecules
Explanation:
Nicotinamide adenine dinucleotide (abbreviated NAD +, and also called diphosphopyridine nucleotide and Coenzyme I), is a coenzyme found in all living cells. The compound is a dinucleotide, as it consists of two nucleotides linked through their phosphate groups with a nucleotide that contains an adenosine ring and the other that contains nicotinamide.
In metabolism, NAD + participates in redox reactions (oxidoreduction), carrying electrons from one reaction to another.
Coenzyme, therefore, is found in two forms in cells: NAD + and NADH. NAD +, which is an oxidizing agent, accepts electrons from other molecules and becomes reduced, forming NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD +. However, it is also used in other cellular processes, especially as a substrate for enzymes that add or remove chemical groups of proteins, in post-translational modifications. Due to the importance of these functions, the enzymes involved in the metabolism of NAD + are targets for drug discovery.
Answer:
Since rain naturally has things dissolved in it, it will always be slightly acidic. However, when rain reacts with certain air pollutants, such as sulfur or nitrogen oxides, the water vapor converts into very diluted forms of sulfuric or nitric acids.

Answer:
The correct option no is 2. To determine if they are prokaryotic or Eukaryota she should look for the <u>nucleus.</u>
Explanation:
Prokaryotes can be described as organisms that are single-celled and lack membrane-bound organelles. Eukaryotes can be described as multicellular organisms and they possess membrane-bound organelles.
In Eukaryotes, the hereditary material is present inside a membrane-bound organelle termed as the nucleus. The prokaryotes do not have a nucleus and their hereditary material is present in the cytoplasm. Hence, option no 2 is correct.
Other structures like DNA and ribosomes are present both in the prokaryotic and eukaryotic cells.
Answer:
Microbes play an incredibly important role in research. Many of the breakthroughs in molecular biology, such as understanding how the genetic code works and how genes are used to make proteins, were made by scientists studying microbes in the laboratory
