Answer:
9.47 x 10^17 meters
Explanation:
To find the distance from Earth to Pluto in meters in scientific notation, we first need to convert 300 light years into meters.
A light year is the distance light travels in one year, and light travels at a speed of approximately 299,792,458 meters per second.
To convert light years to meters, we can use the following steps:
1. Multiply the speed of light by the number of seconds in a year (365 days x 24 hours x 60 minutes x 60 seconds) to find the distance light travels in one year.
299,792,458 meters/second x (365 days x 24 hours x 60 minutes x 60 seconds)
2. Multiply the distance light travels in one year by 300 (the number of light years between Earth and Pluto) to find the distance in meters.
(299,792,458 meters/second x (365 days x 24 hours x 60 minutes x 60 seconds)) x 300
The final answer in scientific notation will be a number between 1 and 10 multiplied by a power of 10.
Therefore, the distance from Earth to Pluto in meters in scientific notation is approximately 9.47 x 10^17 meters.
Answer;
Carbohydrates;starches and sugars
Lipids; fats, steroids
Proteins; phospholipids
Nucleic Acids; DNA and RNA
Explanation;
-All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.
The nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively. They make the proteins that are present in almost every structure and perform almost every function in your body.
-Proteins are the most versatile of all the organic molecules, making up many structures and executing various functions within organisms. Building blocks called amino acids make up proteins. About 20 different amino acids combine to form all of the various types of proteins on Earth.
-Carbohydrates comprise the largest number of organic molecules in organisms. Basically, carbohydrates are sugars; their origin can be traced to photosynthesis, the process by which organisms such as plants use sunlight to transform carbon dioxide and water into food.
-Lipids, perhaps better known as fats, come in different forms in your body and contain the most energy of all the organic compounds.
The equation for the thermal efficiency of a system is given by n = Tc/Thx100 where n is the thermal efficiency, Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir. Dividing 190 by 515 gives us an efficiency of 36.9%.
Answer: A.
63.1%
Explanation: edmentum
3. Denature and decrease its activity
Changes in pH can affect the activity of enzymes. Enzymes have an optimal pH which they function most efficiently, and changes from this pH can cause denaturation of the enzyme. An important aspect of molecular biology is that structure means function. Denaturation affects structure of the enzyme and therefore, function. A pH that is too acidic or basic can disrupt the ionic and hydrogen bonds that maintain the 3D structure. This denaturation results in a loss of enzyme activity rather than increase.

What is the domain?
Archaea
Bacteria
Eukaryota
Explanation:
Both Bacteria and Archaea are prokaryotes, single-celled microorganisms with no nuclei, and Eukarya includes us and all other animals, plants, fungi, and single-celled protists – all organisms whose cells have nuclei to enclose their DNA apart from the rest of the cell.
Answer:
1) organic compounds always contain carbon
Explanation:
organic compounds are molecules that contain carbon atoms bonded to other elements
The correct statement is 'Organic compounds always contain carbon'. Not all carbon-containing compounds are organic, and organic compounds are not exclusive to animal cells nor do they necessarily contain oxygen. Organic compounds can be formed by living organisms, through geological processes, and in the lab.
The true statement about organic compounds is 'Organic compounds always contain carbon'. This is because organic compounds, both natural and synthetic, are characterized primarily by the presence of carbon as the principal element, which is bonded to hydrogen and other carbon atoms. Carbon possesses the unique ability to form up to four covalent bonds with other atoms, resulting in an enormous variety of possible compounds.
It's important to note that not all carbon-containing compounds are considered organic. For instance, carbonates, cyanides, and simple oxides like CO and CO₂ are not classified as organic. Also, contrary to 'Organic compounds can be synthesized only in a laboratory', organic compounds are not only synthesized anthropogenically but are also formed by living organisms and through geological processes. 'Organic compounds are synthesized only by animal cells' and 'Organic compounds always contain oxygen' are, likewise, incorrect, as organic compounds are not exclusive to animal cells and don't necessarily have to contain oxygen.
