1) Sheldon concluded that because youths came from parents who were delinquent in very much the same way that the boys were delinquent, the factors that produce delinquency were inherited.
Sheldon and Eleanor Glueck, two pioneers in the field of criminology, followed the beginning and end of the criminal lives of individuals. The initiation of delinquency, the progression of offences, the continuation of delinquency, and the transition away from delinquency are some of the topics that are discussed in life course theories.
Sheldon came to the conclusion that the elements that promote delinquency are hereditary since the boys who committed crimes had parents who had committed crimes in a manner that was extremely comparable to the boys' own criminal behaviour.

A.The microbe is isolated from the diseased host and grown in pure culture.
B.The same strain of microbe is obtained from a newly diseased host.
C.The microbe is found in all cases of the disease but is absent from healthy individuals.
D.When the microbe is introduced into a healthy, susceptible host, the same disease occurs.
When linking a bacterium to a latent infection like Lyme disease or tuberculosis, then the microbe will be found in all the cases of the disease but they are absent from healthy individuals and when the microbe is introduced in the body of a healthy and a susceptible host, the same disease will occur.
The correct options are C and D.
Koch's postulates were formed basically as guidelines in order to establish that microbes cause certain specific diseases. Since these rules were developed for the living agents, especially bacteria, and therefore they are not applicable to the inanimate pathogens such as viruses as well as infectious proteins.
Latent infections, like tuberculosis, only happen to cause symptoms in a fraction of the infected individuals. Also, the period of time before these infected individuals show symptoms also variable. So, it is very unlikely that a scientist will only find the microbe in the diseased individuals and also it is unlikely that symptoms would occur in all hosts.

Which of the following is true about genes that are located on different chromosomes? These genes are inherited independently of each other. Only the dominant alleles of these genes tend to be inherited together These genes are always inherited together These genes are more likely to undergo mutation.
Genes that are located on different chromosomes are inherited independently of each other. The correct answer is A.
Genes that are located on different chromosomes are inherited independently of each other, which means that the inheritance of one gene does not influence the inheritance of another gene located on a different chromosome. The correct answer is A.
This occurs because during meiosis, the chromosomes that carry the genes are separated randomly into different gametes, so the combination of chromosomes and the genes they carry in each offspring is unique.
The independence of gene inheritance means that different combinations of alleles for different genes can be passed on from generation to generation, which contributes to the genetic diversity within populations.

TRUE/FALSE. elongation of the polypeptide chain is terminated when a stop codon is incorporated into the newly synthesized protein.
The given statement is True.
Translation is the process by which ribosomes read the information encoded in messenger RNA (mRNA) and synthesize a corresponding protein. The ribosome reads the mRNA codons three nucleotides at a time and matches each codon to a specific amino acid. When the ribosome reaches a stop codon, which does not code for an amino acid, it signals the termination of protein synthesis. This stop codon acts as a signal for the release of the newly synthesized protein from the ribosome. In conclusion, elongation of the polypeptide chain is terminated when a stop codon is incorporated into the newly synthesized protein. The stop codon acts as a signal for the release of the newly synthesized protein from the ribosome, and is a critical step in ensuring the accuracy and efficiency of protein synthesis.To know more about RNA visit:

Which of the following might result from a parathyroid tumor which causes oversecretion of parathyroid hormone?
A) Joint inflammation leading to osteoarthritis
B) Bone loss due to stimulation of osteoclasts
C) Bone growth due to stimulation of osteoblasts
D) Conversion of cartilage to bone
Bone loss due to stimulation of osteoclasts might result from a parathyroid tumor which causes over secretion of parathyroid hormone. The correct answer is B.
A parathyroid tumor that results in over secretion of parathyroid hormone can lead to a condition known as hyperparathyroidism.
In hyperparathyroidism, the elevated levels of parathyroid hormone cause an increase in the activity of osteoclasts, which are cells that break down bone tissue. This increased activity leads to a net loss of bone mass and can result in bone fractures, joint pain, and other skeletal abnormalities.
On the other hand, parathyroid hormone has a regulatory role in bone metabolism and can also stimulate the activity of osteoblasts, which are cells that build bone tissue.
However, in the context of a parathyroid tumor and hyperparathyroidism, the net effect is bone loss due to the increased activity of osteoclasts. Joint inflammation leading to osteoarthritis (Option A) and conversion of cartilage to bone (Option D) are not direct effects of hyperparathyroidism.

how alleles gets distributed to offspring form parents
how many markers are necessary to map new genes to an exact location on the chromosomes described below using linkage
The number of markers necessary to map new genes to an exact location on a chromosome using linkage depends on the size of the chromosome.
Linkage mapping is based on the principle that genes that are close together on a chromosome are more likely to be inherited together than genes that are far apart. By tracking the inheritance patterns of multiple markers, it is possible to determine the relative positions of genes on a chromosome. The more markers that are used, the more precise the mapping will be. In general, two markers are sufficient to determine the relative positions of genes, but more markers are needed to define their exact location. The number of markers required can be estimated based on the size of the chromosome, the frequency of recombination between the markers and the gene of interest, and the desired level of resolution. A rough estimate is that at least 5-10 markers are needed to map a gene to an exact location on a chromosome. However, the actual number may be higher or lower, depending on the specific circumstances.To know more about chromosomes visit:
