Answer: proteins
Explanation:
All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion
The structure is most likely found in both viruses and cells is protein. Thus, option B is correct.
What is virus?A virus is a microscopic organism that serves as infectious agent and divides only inside the living cells of an organism. Viruses infect all living organisms such as plants, animals, human beings including bacteria and other microscopic organism.
Virology is the branch of science which deals with the study of viruses.When virus infected a host cell it divides rapidly and production can be observed and by dividing rapidly lots of original version of viruses are produced.
When the virus enters into a infected cell or living cell, viruses exist in dead form particles known as virions. In open air viruses are non-living but when they entered into a living cell of an organism they become active as well as able to reproduce.
Therefore,The structure is most likely found in both viruses and cells is protein. Thus, option B is correct.

3. What can you say about the general relationship of the charge of the anion to the subscript of the cation?
Answer:
Cations are positively charged ion while anions are negatively charged ions formed by loosing and gaining of electrons respectively. Transition metals are metals in the middle of the periodic table with multiple oxidation states. The charge on the transition metal is equal to the oxidation state which varies from +1 to +7. The charge of transition metal can also be determined in neutral compound as long as one knows the charge or the oxidation state of the other atom in the compound. The charge of transition can also be determined in the case of neutral complexes where the transition element has combined with other atoms to form molecular complexes that are either positively or negatively charged, e.g. MnO4-. Lastly Neutral transition metal compounds which are soluble in water have a charge of +3 or less than+3.
Cations are positively charged particles and anions are negatively charged elements.
What are cations?Anions are negatively charged ions created by losing and receiving electrons, whereas cations are positively charged ions. Transition metals are middle-of-the-periodic-table metals with a variety of oxidation states.
The oxidation state, which ranges from +1 to +7, is equivalent to the charge on the transition metal. As long as one is aware of the charge or oxidation state of the other atom in the compound, one may also determine the charge of a transition metal in a neutral compound.
When the transition element has joined with other atoms to form neutral molecular complexes that are positively or negatively charged, such as MnO4-, it is also possible to detect the charge of the transition.
Therefore, Cations are positively charged particles and anions are negatively charged elements.

suggest why digestion (the breakdown of large macromolecules) is largely performed by extracellular enzymes
Answer:
Enzymes speed up the breakdown of macromolecules in food to small molecules
Explanation:
During digestion, the macromolecules that make up food are hydrolyzed by digestive juices to molecules of a size that allows their absorption through the lumen of the tract. In this way, proteins are divided into amino acids, carbohydrates into glucose and other monosaccharides, and fats into glycerol and fatty acids. Digestion and absorption take place mainly in the small intestine.The production of extracellular enzymes that, once released into the medium, degrade the substrate and then allow their diffusion / transport.

Which nucleotides can pair together? Select all that apply. adenine (A) & cytosine (C) cytosine (C) & guanine (G) cytosine (C) & thymine (T) adenine (A) & thymine (T) adenine (A) & guanine (G) thymine (T) & guanine (G)
The nucleotides which base pairs together in the DNA helix are adenine(A) to the thymine (T) and Cytosine(C) to the Guanine (G). A purine always base pairs against a pyrimidine.
What are nucleotides?Nucleotides are the monomeric units of the genetic material i.e., DNA present in the nucleus of cell. Nucleotides are made up of three components which include a nitrogenous base, a deoxyribose sugar in case of DNA or a ribose sugar in case of RNA, and a phosphate group moiety.
The nitrogenous bases are of two types on the basis of their structures: Purines and Pyrimidines. Purines are double-ring structures which contain an imidazole ring attached to a pyrimidine ring. This include Adenine and Guanine. Pyrimidines are single-membranous structures which are similar to pyridine. Pyrimidines include cytosine, thymine and uracil. In DNA, thymine is present whereas in RNA, uracil is present.
A purine always base pairs with a pyrimidine. In case of DNA, an adenine forms two hydrogen bonds to base pair with thymine and vice versa whereas guanine forms three hydrogen bonds while pairing with cytosine residues and vice versa.

Which of the following is true about RNA?
tRNA brings in an amino acid and bonds with mRNA
mRNA carries the code of rRNA to the nucleus.
mRNA is made from tRNA during transcription.
rRNA helps tRNA make a copy of the DNA gene.
Answer:
the right answer is
tRNA bonds with mRNA, bringing in amino acids.
Explanation:
Ribonucleic acid is a single-stranded structure. The true statement is tRNA brings in an amino acid and bonds with mRNA. Therefore, the correct answer is option 1.
The Transfer RNA, or tRNA, transports amino acids to the ribosomes, the cell's protein-making factories, during the synthesis of proteins. An anticodon, which is a particular set of nucleotides on each tRNA molecule, is complementary to the codon on the mRNA (messenger RNA) molecule. From the DNA in the nucleus to the ribosomes in the cytoplasm, the mRNA transports the genetic information.
The tRNA with the complementary anticodon brings in the exact amino acid that is coded by that codon when the ribosomes read the codon on the mRNA. In order for the ribosomes to assemble the amino acids into a protein chain in the proper sequence, the tRNA molecule then forms a connection with the mRNA.
Therefore, the correct answer is tRNA brings in an amino acid and bonds with mRNA, i.e. Option 1.

Which of the following is the mean number per cross of F2 generation offspring that are the result of crossing over
Answer:
2.2
Explanation:
Since all of the mice in the F1 generation are heterozygous for both traits, they contain a copy of each on separate chromosomes. (AB on one from parent 1 and ab on the other from the parent 2.) If these chromosomes split away from each other without crossing over, the F2 offspring can ONLY by AABB or aabb. This means that any heterozygous combinations are the result of crossing over and must be counted. When all are counted, we get a total of 11, or 2.2 per cross.
To calculate the mean number per cross of the offspring that result of crossing over, we need to make an addition of individuals that result from crossing-over, and divide the result by the number of crosses. The result is 2.2.
---------------------
According to the statement, crosses were as follow
Cross 1) Between two true-breeding
Parentals) LLBB x llbb
F1) 100% LlBb
Cross 2) Between two dihybrids
Parentals) LlBb x LlBb
The results of the F2 are
Phenotype Cross1 Cross2 Cross3 Cross4 Cross5
Long-Black 6 5 5 6 7
Long-White 1 1 0 2 2
Short-Black 0 2 1 1 1
Short-White 2 3 3 2 2
If there is no crossing-over, offspring will have the same chromosomes as parentals, which are Long-Black (LB) or Short-White (lb), because these chromosomes separate without interchanging segments.
However, if there is crossing over, these chromosomes interchange segments, and the result is Long-White (Lb) and short-black (lB).
So now, we need to count how many individuals from the F2 are a result of crossing-over.
Phenotype Cross1 Cross2 Cross3 Cross4 Cross5 Total
Long-White 1 1 0 2 2 6Short-Black 0 2 1 1 1 511
Eleven individuals result from crossing over. But we need to calculate the mean number per cross.
So, since there are 5 crosses, we need to divide the total number of individuals that are the result of crossing over by the total number of crosses.
total number of individuals = 11total number of crosses = 5Mean number per cross of F2 generation ⇒ 11/5 = 2.2
The mean number per cross of F2 generation offspring that are the result of crossing over is 2.2
