Answer:
No the cell wall is only found in plants
Explanation:
Answer:
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host.

Explanation:
polymers
water and polymers
none of the above
Answer:
Water and polymers.
Explanation:
Dehydration reaction may be defined as the reaction in which a water molecule is released during the process of reaction. Large molecules are joined together by the process of dehydration.
Polymers are formed by reacting the monomers together with a release of small molecules like water. Hence, water and polymers are formed by dehydration reaction.
Thus, the correct answer is option (3).
Dehydration synthesis leads to the formation of water and polymers. Hence, the correct option is C.
Dehydration is the process of water loss. It involves the formation of two smaller molecules to form a larger molecule with a loss of water. The macromolecules like carbohydrates, proteins, and nucleic acids, are synthesized by a dehydration process which is essential for the survival of living organisms.
Thus, the dehydration synthesis leads to the formation of water and polymers. Hence, the ideal solution is option C.

Answer:
Patchy forest.
Explanation:
The patchy forest hypothesis is the second hypothesis that helps to explain the origin of the hominids. The hypothesis was developed by Peter Rodman and Henry McHenry.
This hypothesis suggest that the evolution of bipedalism is energy efficient in the environment that contain few tress. The patchy forest result in the dispersion of the forest and this might result in the energy efficiency of bipedalism by walking upright and collect their food with hands.
Thus, the correct answer is patchy forest.
Answer:
Option A, helps prevent rapid breakdown of the messenger RNA
Explanation:
The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.
Hence, option A is correct
The reaction of calciumsulfate is double displacement reaction, the reaction of copper and oxygen is synthesis reaction. The reaction of copper oxide and oxygen is single displacement reaction.
When atoms establish or break chemicalbonds, chemical processes take place. Reactants are the substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction.
Combination, decomposition, single-replacement, double-replacement, and combustion are the five fundamental types of chemicalreactions. You can classify a reaction into one of these groups by looking at the reactants and products.
Calcium sulphate undergoes a doubledisplacement reaction, whereas copper and oxygen undergo a synthesis reaction. Copper oxide and carbon is single displacement reaction.
Thus, first is double displacement reaction, second is synthesis reaction, as well as third reaction is single displacement reaction.
