Select the correct answer. Which of the following is a correctly balanced equation? A. NaClO3 → NaCl + 3O2 B. 2HgO → 2Hg + O2 C. 2ZnS + O2 → 2ZnO + 2SO2 D. 4CO + Fe3O4 → 4CO2 + Fe E. 2Fe + 2Cl2 → 2FeCl3

Answers

Answer 1

The right answer is 2HgO → 2Hg + O2

Balancing a balance equation consists of finding the right stoichiometric coefficients. These coefficients (placed in front of each molecule) balance the number of each of the different atoms involved during a chemical reaction.

In this reaction, we find on both sides the same number of atoms: two oxygen atoms and two atoms of mercury.

Answer 2

Answer:

B. 2HgO → 2Hg + O2

Carbohydrates

Carbohydrates are polymers of carbon, hydrogen and oxygen. They can be classified as monosaccharides, disaccharides and polysaccharides. Carbohydrates are found in starch, fruits, vegetables, milk and sugars. They are an important source of a healthy diet.

Nucleic Acids

The nucleic acids include DNA and RNA that are the polymers of nucleotides. Nucleotides comprise a pentose group, a phosphate group, and a nitrogenous base group. All the hereditary information is stored in the DNA. The DNA synthesised into RNA and proteins.

Proteins

Proteins are the polymers of amino acids. These include the carboxylic and the amino group. There would be no lipids or carbohydrates without proteins because the enzymes used for their synthesis are proteins themselves.

Lipids

Lipids are a hydrophobic set of macromolecules, i.e., they do not dissolve in water. These involve triglycerides, carotenoids, phospholipids, and steroids. They help in the formation of the cell membrane, formation of hormones and in the and as stored fuel.

In a signal transduction pathway, fine tuning of the cellular response occurs in several steps. Which of the following best describes how the response would be affected if the molecular changes that occur during a signaling pathway lasted for a prolonged period?

Inactivation mechanisms would be triggered before the pathway could be completed.
Receptors would be unable to return to their inactive form and respond to new signals.
Scaffolding proteins would cause potentially harmful signal amplification in the cytosol.
Signaling proteins would be unable to take part in multiple pathways, as specificity is lost.

Answers

Answer: Receptors would be unable to return to their inactive form and respond to new signals.

Explanation:

Many signaling pathway involves the regulation of the protein synthesis. It involves the turning off or on of some of the specific genes present in the nucleus. If the receptors become unable to resume to the inactive form the may not be able to produce  new signals during protein synthesis. The final activated molecule in a signal pathway may not function as transcription factor.

Receptors would be unable to return to their inactive form and respond to new signals.

What are the four major categories of Marco molecules? Describe the basic structures and primary functions of each

Answers

Answer:

Explanation:

question 1:

Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules. these are carbohydrates, lipids, proteins, and nucleic acids. Each is an important cell component and performs a wide array of functions.

question 2:

Carbohydrates

Carbohydrates are, in fact, an essential part of our diet; grains, fruits, and vegetables are all natural sources of carbohydrates. Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants.

Lipids

Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon–carbon or carbon–hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals.

Proteins

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes. mail me via at 16jacktwinwritters for more explanation and further clarification. Each cell in a living system may contain thousands of proteins, each with a unique function. Their structures, like their functions, vary greatly.

Nucleic Acids

Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.

Provitamin A, also known as beta-carotene, is necessary for human health. People who do not make this substance suffer serious medical problems. Which application of genetic technology has been the MOST promising for treating people who suffer from a deficiency of provitamin A?

Answers

Answer:

The application of genetic engineering called golden rice

Explanation:

Golden Rice is a genetically engineered biofortified crop designed by biosynthesizing beta carotene in the edible part of rice. Golden rice was created by transforming rice with two beta-carotene biosynthesis genes: psy (phytoene synthase) from daffodil ('Narcissus pseudonarcissus') crtI (phytoene desaturase) from the soil bacterium Erwinia uredovora.

Golden rice was genetically modified to provide beta-carotene, which is converted into vitamin A in the body, which is an essential nutrient that white rice lacks.

Some entomologists believe that the evolutionary reason that plants expend energy to produce fall color is to warn pests. A plant that is healthy is able to produce lots of carbohydrates, and therefore more anthocyanins. Some insect pests will not lay eggs on bright colored leaves. Instead, they will find a “weaker” drab/dull colored tree on which to lay eggs. Some scientists believe that anthocyanins may act as a sunscreen to inhibit the destruction of the chlorophyll, help to prevent frost injury to leaf tissues, or limit water loss during dry spells in autumn. As far as the fall foliage watcher is concerned, their purpose is simple—they signal a last hurrah for the growing season and delight the optic nerve.

How do trees turn color?

In the fall, trees break down the green pigments and nutrients stored in their leaves. The nutrients are shuttled into the tree's roots for reuse in the spring. It's then that the trees take on their autumn hues. As leaves lose their chlorophyll, other pigments become visible to the human eye, according to Bryan A.
