All of these are examples of evidence used to support the hypothesis of endosymbiosis, EXCEPT:a. Mitochondria and plastids contain circular DNA molecules similar to the circular chromosomes of bacteriab. Mitochondria and plastids, like prokaryotes, only contain genetic material in the form of RNAc. Mitochondria and plastids can replicate themselves in a process similar to prokaryotesd. Mitochondria and plastids have their own ribosomes and enzymes that can be used to transcribe and translate DNA into proteinse. Mitochondria and plastids have a double membrane (inner and outer) Solution Out of the above options , the correct will be B. Mitochondria and plastids a have their genetic material in the form of DNA not RNA. They donot have any such machinary for their expression , so this option is incorrect regarding endosymbiosis. Otherwise rest all the sentenses are true. They have circular genome like Prokaryotes, and can replicate and also have double membrane layer..

DNA replicates conservatively, Semiconservatively, liberally, by hybridization by congression. A bacterial artificial chromosome is a vector with centromeres, telameres, and an origin of replication. with centromeres and an origin of replication derived from a plasmid with an origin of replication. derived from a plasmid with a centromere, derived from a complete bacterial chromosome. The central dogma of molecular biology is____________ rightarrow ___________ rightarrow ___________ Which of the following correctly represents the distinction between the terms \"genotype\" and \"phenotype\"? Phenotype is the genetic composition of an organism, while genotype is the physical appearance. There is no difference between a genotype and a phenotype. A phenotype is dominant and a genotype is recessive. The genotype is the genetic composition of an organism, whereas the phenotype is its physical appearance. Solution 5. b) semiconservatively The DNA is doube stranded with two strans in antipolar nature. During replication the two strands sepearate. A new strand is added to each one of them and thus we get two new double stranded DNA strands with one old strand and one new strand. Hence it is called Semi- conservative. 6. c) Derived from plasmid with an origin of replication. The Bacterial artificial chromosome is derived from fully functional F plasmid. It is used to clone large DNA inserts and express inside E. coli. It has its own origin of replication and genes for homologous recombination. This Ori, helps it to replicate on its own inside the bacterial cell and maintain itself. However unlike actual chromosome it does not contain centromers or telomeres. Hence answer is option C. 7. DNA --> RNA --> Protein It is the central dogma of Biology, in which the DNA acts as genetic material passes on its information to RNA (mRNA-messenger RNA) by a process called as Transcription. The mRNA is later Translated with the help of ribosomes into proteins. Athough there is another transition exists in which RNA is converted back to DNA, which is called reverse transcription ( Not mentioned in the question ). 8. d) The genotype is the genetic compostion of an organism, whereas the phenotype is its physical appearance. The genotype is the genetic content, what genes the organism possesses. These genes gets transcribed and translated into proteins, which make up the appearance of the organism, in other words Phenotype. Phenotype depends largely on the genotype and genotype is hereditory..

I have to make a program for my C class and im stuck on the part where i have to calculate the variance with elements from my array. This is exactly what im suppose to do: Reset the sum variable to 0 Using another for loop (which needs its own loop variable), run through all valid elements of the array, starting from index 0. Inside the loop: Use the sum variable to accumulate the numerator of the variance formula shown on page 1. After the end of this loop, compute the variance by dividing the new sum by the dataElementsToProcess parameter. this is the entire function bool GenerateStatistics(FILE *fp2, double myArray[], int dataElementsToProcess) { if (fp2 == NULL && myArray == NULL && dataElementsToProcess < 1) { return false; } else { int i = 0,o = 0; int sum = 0, sum1 = 0; double maxValue = 0; double minValue = DBL_MAX; double mean, variance, stdDeviation; for (int i = 0; i < 600; i++) { sum += myArray[i]; if (myArray[i] > maxValue) { maxValue = myArray[i]; } if (myArray[i] < minValue) { minValue = myArray[i]; } } mean = sum / dataElementsToProcess; sum = 0; for (int o = 0; o < 600; o++) { sum += myArray[o]; } variance = sqrt(pow((sum - mean), 2) / (dataElementsToProcess)); stdDeviation = sqrt(variance); fprintf(fp2, \"Reaction Rate Statistics:\ \ \"); fprintf(fp2, \"Number of experiments = %d\ \", dataElementsToProcess); fprintf(fp2, \"Minimum rate\\t\\t= %f\ \", minValue); fprintf(fp2, \"Maximum rate\\t\\t= %f\ \", maxValue); fprintf(fp2, \"Arithmetic mean\\t\\t= %f\ \", mean); fprintf(fp2, \"Variance\\t\\t= %f\ \", variance); fprintf(fp2, \"Standard deviation\\t= %f\ \ \ \", stdDeviation); } return true; } Solution Here in the function you have average - mean Noofelements - dataElementsTo Process Variance formula is V = summation over i=1 to n ((xi - mean )*(xi - mean)) So perform like this using a for loop over my_array double V=0.0 for(int i=0;i<600;i++) { V=V+pow((my_Array[i]-mean),2) } Now calculate standard deviation using sqrt of variance sd=0.0 sd=sqrt(V).

describe a real-life example of selection against a homozygous recessive genotype Solution When both the alleles of a particular chromosome are recessive, it’s called homozygous recessive for that chromosome pair. There are few real life examples of homozygous recessive such as albinism, cystic fibrosis etc. Albinism is congenital disorder in humans that is a characterized by absence of pigment in skin, eyes, and hairs. Absence of pigment may be partial or complete. Lack of skin pigmentation in albinism makes individual more sensitive to sunlight and susceptible skin sunburn and skin cancers. Albinism is also associated with visions defects such as amblyopia, photophobia and nystagmus. This disorder is due to inheritance of recessive alleles which has defect/ absence of tyrosinase involved in the production of melanin..

Write a class named Deque20, placed in the file Deque20.java. It should behave exactly as described in the Java interface Deque (Google: \"Java 8 Deque\") except that it should only implement the following methods: a no-argument constructor, addFirst, addLast, removeFirst, removeLast, peekFirst, peekLast, and size. Your class should not extend or implement any class or interface. It must use an array as its storage, allow generic types (E), and be as efficient as possible. The Deque javadoc mentions several exceptions, but you should only return NullPointerException (if someone tries to add a null reference to the Deque) and NoSuchElementException (if someone tries to remove an item from an empty Deque). Your deque should store objects in a circular array. Probably the simplest implementation has objects with fields The meaning being that the elements currently in the deque are at positions list[first_index], list[(first_index+1)%list.length], list[(first_index+2)%list.length],..., list[(first_index+num_elems-1)%list.length]. The modulus is necessary because first_index might be near the end of the array and adding to it might result in an index that\'s out of bounds. When an add operation would cause the capacity of the array to be exceeded, you should double the size of the array by creating a new array of twice the size and copying the old array contents into the new. Do not worry about ever reducing the size of an array. Also, whenever a reference is removed from your deque, the old array location should be set to null so that the garbage collector knows that the old item is no longer referred to by the deque. Solution public class Deque20 { private int first_index; private int num_elems; private Object[] list; Deque20(){ first_index = 0; num_elems = 0; list = new Object[20]; } private void doubleSize(){ Object[] arr = new Object[2 * list.length]; for(int i = 0; i < list.length; ++i){ arr[i] = list[(i + first_index) % list.length]; } list = arr; } public void addFirst(E val){ if(list.length == num_elems){ doubleSize(); } int index = (first_index + list.length - 1) % list.length; list[index] = val; ++num_elems; } public void addLast(E val){ if(list.length == num_elems){ doubleSize(); } int index = (first_index + num_elems) % list.length; list[index] = val; ++num_elems; } public E removeFirst(){ int index = first_index; E ret = (E) list[index]; first_index = (first_index + 1) % list.length; return ret; } public E removeLast(){ int index = ((first_index + num_elems) % list.length) - 1; E ret = (E) list[index]; --num_elems; return ret; } public E peekFirst(){ return (E) list[first_index]; } public E peekLast(){ int index = ((first_index + num_elems) % list.length) - 1; return (E) list[index]; } public int size(){ return num_elems; } }.

What is Incorporation by Reference? and How is it used in a contract? Solution Incorporation by reference is an act of including second document within the first document by giving only reference in first document. Ie if in first document only a single line is kept giving reference of second document. than the secound document will be part of first document. Incorporation by reference is often done in creating law as well in contract law nad trust and estate law Incorporation by reference is used in contract by way of terms and condition. For example there are general set of terms and condition to contarct now instead of including all the tems and condtion to contract a company can just give reference to it, making it binding to the companies entering the contract. Thus it is very important to read document if it is included by reference.
