Explanation:
1. AMINO ACIDS are the basic building block of proteins; they contain a carboxyl group (-COOH) and an amino group (-NH 2) in their structure. 2. A CATALYST is any substance that accelerates a chemical reaction without being used up in the reaction. They do this by lowering the activation energy of the reaction. 3. Deoxyribose nucleic acid (DNA) is a complex molecule containing the genetic code. It carries all the genetic information of living organisms. 4. AN ENZYME is a protein molecule that is specialized to speed up a specific chemical reaction in biological systems. It is referred to as a biological catalyst because it speeds up a chemical reaction in living systems. 5. NUCLEIC ACID is a sequence of sugars, phosphates, and nitrogenous organic bases. A nucleic acid (DNA and RNA) is a polymer of nucleotides, which are composed of the three molecules mentioned above. A sequence of nucleotides forms a NUCLEIC ACID. 6. PROTEIN is a large, complex organic molecule consisting of a large number of amino acids linked together by peptide bonds. The amino acid building blocks are linked together in a condensation reaction and catalyzed by Peptidyl transferase enzyme. 7. Ribonucleic acid (RNA) is a type of nucleic acid that participates in the synthesis of proteins. RNA is of three types viz: mRNA, rRNA and tRNA. They all play a role in the process of protein synthesis. 8. A SUBSTRATE is a compound that is involved in a chemical reaction and is chemically changed by the reaction.

help meee,A study was carried out on the emission of N2O in a sewage treatment plant (ETE) in the metropolitan region of Rio de Janeiro.
of January. During the study period, this ETE received sewage from 470,000 inhabitants. One particularity observed is that in addition to receiving domestic sewage, this station received, during a certain period of the day,the material leached from a sanitary landfill, responsible for causing an increase in the load of organic matter in the ETE in study. Continuous measurements of dissolved oxygen concentration and N2O emission were carried out at this station for 3
hours, in the period prior to the entry of the material leached from the landfill and in the period immediately after the entry of this material.
1-Why, soon after the material from the landfill, the concentration of dissolved oxygen decreased;
2-Why is there a significant increase in the emission of N2O soon after the entry of the leached material from the landfill? What bacterial processes can contribute to the increase in the emission of this observed gas
in this experiment?
The emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.
What is dissolved oxygen?The term dissolved oxygen refers to the amount of oxygen that is present in a water body. Now, we know that the addition of organic matter into water requires oxygen to break it own thus the dissolved oxygen content will go down in response to the added organic load.

which dental material would you say is the most versatile and widely used today and why?
One of the most adaptable restorative materials in dentistry is dental amalgam. It accounts for over 75% of all restorative materials used by dentists.
What is amalgam?Dental amalgam is a mixture of liquid mercury and metal alloys used to treat cavities caused by tooth decay in dentistry. [1] Mercury (50%) is typically found in low-copper amalgam, along with silver (22–32%), tin (14%), zinc (8%), and other trace metals.
Because of the constant expansion and contraction of amalgam fillings, they can sometimes shatter the tooth. Leakage is also less likely with composite fillings. A leaking filling indicates there is a small breach between the filling and your tooth, which allows dirt and saliva to enter and cause decay.

GENES are the fundamental unit of heredity that transmit albinism from one generation to the next. Thus, the correct option is A.
What is DNA?Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce.
Because they contain unique sets of instructions to encode certain proteins, which are passed down across generations, genes are regarded as the fundamental functional and structural components of heredity (i.e., they are inherited).

The basic unit of heredity that carries the trait of albinism from parent to offspring is GENES. Thus, option "B" is correct.
What are genes?Genes are considered the basic functional and structural units of heredity because they contain specific sets of instructions to encode specific proteins, which pass across generations (i.e., they are inherited).
During gene expression, specific fragments of DNA (i.e., genes) are used as templates to create specific complementary RNA sequences called messenger RNAs (mRNAs) by a process called transcription.
Subsequently, these mRNAs are used to synthesize proteins by a process called translation.
The proteins arrange in the cell to produce specific phenotypes, i.e., specific observable features or traits.

is water losing through transpiration harmful or benefical for plant
Answer:
Beneficial. Read below
Explanation:
Water naturally does evaporate from the leaves. When it does, it makes a sort of suction in the 'pipes' of the plant. Think of it like when you drink from a cup with a straw. You take juice out from the straw by sucking it but that makes the juice still in the cup go up to replace that lost juice. This is how plants absorb water from the roots. If transpiration didn't happen, plants wouldn't be able to absorb water apart from osmosis but that would be too slow.
Which of the following is most likely to happen if oxygen is not able to enter a cell?
The cell will not be able to produce energy
The cell will not be able to get rid of waste
The cell will not be replaced when damaged
The cell will not be able to split into daughter cells

Which forms as a result of compressional stress?
anticline and syncline
normal fault
strike-slip fault
fault-block mountain
Anticline and syncline forms as a result of compressional stress. Thus, the correct option is A.
What is anticline ?Folds known as anticlines occur when formerly horizontal strata have been folded upward and the two limbs deviate from the surface.
When rocks deform in a ductile way, they may bend or fold, and the resulting structures are known as folds, rather than shattering to produce faults or joints. Folds are caused by compressional or shear pressures operating over a long period of time. Such folds originate from rocks that we often consider brittle behaving ductilely when the strain rate is low and/or the temperature is high.
