Ribosomes get their recipe for making proteins from the
A. Trna
B. Nucleus
C. Mitochondria
D. rer
Answer:
nucleus
Explanation:
The main job of the ribosome is to make proteins for the cell. There can be hundreds of proteins that need to be made for the cell, so the ribosome needs specific instructions on how to make each protein. These instructions come from the nucleus in the form of messenger RNA. Messenger RNA contain specific codes that act like a recipe to tell the ribosome how to make the protein.
imagine you have discovered a new species of bacteria. to begin your investigation of this organism, you run an assay (test) on the total nucleotide content of the bacterial dna. if the cytosine content of dna from the bacterial cells is 40%, what is the adenine content? group of answer choices 40% 60% 20% 10% it is not possible to calculate this number for prokaryotes.
To begin the investigation of a new species of bacteria, an assay is run on the total nucleotide content of the bacterial DNA. If the cytosine content of DNA from the bacterial cells is 40%, the adenine content would be 10%.It is possible to calculate the adenine content from the given information because of the complementary base pairing rules of DNA.
Adenine pairs with thymine (A-T), and cytosine pairs with guanine (C-G). The sum of the percentage of adenine and thymine in DNA is equal to the sum of the percentage of cytosine and guanine.
Therefore, if the cytosine content of DNA is 40%, then the guanine content is also 40%. The sum of the percentage of adenine and thymine would then be 60%, which means that the adenine content is 30%.
However, adenine pairs with thymine, and not with cytosine.
Therefore, the adenine content is half of the total of adenine and thymine in DNA, which is 30%.
Therefore, the adenine content of the DNA from the bacterial cells is 10%.

what would be the expected ratio of genotypes in a cross between two parents who were both heterozygous?a. 50% homozygous dominant, 50% homozygous recessiveb. 25% homozygous dominant, 50% heterozygous, 25% homozygous recessivec. 100% homozygous recessived. 100% heterozygouse. 100% homozygous dominant
The expected ratio of genotypes in a cross between two parents who were both heterozygous is: 25% homozygous dominant, 50% heterozygous, 25% homozygous recessive. When two parents who are heterozygous are crossed, it results in a monohybrid cross. For a monohybrid cross, the ratio of the genotypes of the offspring is 1:2:1.
It means that out of four offspring, one will be homozygous dominant, two will be heterozygous, and one will be homozygous recessive. In a monohybrid cross, the genotype of one parent is represented along with the genotype of another parent. In the case of a heterozygous cross, each parent has one dominant allele and one recessive allele.
When the two parents are crossed, the possible combinations of their gametes can be written in the Punnett square. The Punnett square below shows the possible genotypes of the offspring from the heterozygous cross: The offspring's genotypic ratio will be 1:2:1, which means that 25% of the offspring will be homozygous dominant (AA), 50% of the offspring will be heterozygous (Aa), and 25% of the offspring will be homozygous recessive (aa). Hence, option B is correct.

suppose that after an environmental change, foxes with shorter and longer legs are more abundant in the population that the average, medium length legs. the two extreme phenotypes are also more likely to survive and reproduce. this is and example of selection.
The given statement is a clear depiction of directional selection. It is a natural mechanism of evolution that causes a shift in a particular direction by selecting individuals with an extreme variation in a characteristic. It occurs when a certain phenotype is favored over another, causing the frequency of the favored phenotype to increase over time.
In directional selection, the shift in frequency occurs because individuals with certain traits are more successful in surviving and reproducing in a given environment, leading to the increase in their frequency within the population. In the given scenario, the environmental change caused a change in the selective pressure on foxes with respect to their leg length.
As a result, foxes with shorter and longer legs were more likely to survive and reproduce, leading to an increase in their abundance within the population. This is a clear example of directional selection as the shift in frequency of the extreme phenotypes (shorter and longer legs) is in one direction (i.e., towards higher frequency), leading to a change in the population over time. Therefore, this scenario exemplifies directional selection in the population.

which process is endergonic? which process is endergonic? cellular respiration the synthesis of glucose from carbon dioxide and water the burning of wood the breakdown of glucose
Endergonic processes are processes that require energy to proceed. Cellular respiration, which is the breakdown of glucose, is endergonic in nature. In this process, energy is consumed to release energy from glucose in order to be used by the cell.
What is Cellular Respiration Cellular respiration is the process in which cells obtain energy from food. The breakdown of glucose and other molecules from food into carbon dioxide and water is a part of this process. This reaction releases energy in the form of ATP (adenosine triphosphate), which can be used by the cell to perform various functions.
There are three stages of cellular respiration: glycolysis, the citric acid cycle, and the electron transport chain. The first stage, glycolysis, occurs in the cytoplasm of the cell and does not require oxygen.
The second stage, the citric acid cycle, occurs in the mitochondria and is oxygen-dependent. The third stage, the electron transport chain, also occurs in the mitochondria and is also oxygen-dependent.The breakdown of glucose is endergonic because it requires energy to occur.

What are the advantages and disadvantages of generic and condition specific preference- based measures of health and quality of life?"
Generic preference-based measures offer standardized comparability and broad applicability, and condition-specific measures provide enhanced sensitivity and relevance for specific populations, addressing their unique characteristics and domains of importance.
Generic preference-based measures of health and quality of life, such as the EQ-5D and SF-6D, offer several advantages. Firstly, they provide a standardized framework for comparing health outcomes across different conditions, populations, and interventions. This allows for broader comparisons and economic evaluations.
Generic measures also facilitate the calculation of quality-adjusted life years (QALYs), which are widely used in cost-effectiveness analyses. Furthermore, generic measures allow for comparisons between health and non-health sectors, aiding decision-making in resource allocation.
However, generic measures also have limitations. They may lack sensitivity to specific aspects of certain conditions that are not adequately captured by the generic dimensions.
This can result in reduced discriminatory power and responsiveness, particularly in conditions with unique characteristics or domains of importance.
Additionally, generic measures may not fully capture the preferences and values of specific patient groups, leading to potential bias and reduced relevance for certain populations.
Finally, generic measures may not capture important health-related outcomes or specific treatment effects, limiting their ability to assess interventions accurately in some contexts.

the pedigree above shows a disease with a recessive pattern of inheritance. what is the probability individual ii-4 is heterozygous for the disease allele?
To determine the probability of individual ii-4 being heterozygous for the disease allele in a pedigree with a recessive pattern of inheritance, we need additional information about the genotypes of other family members or the prevalence of the disease in the population.
In a recessive pattern of inheritance, individuals with the disease allele must inherit two copies (one from each parent) in order to express the disease phenotype. If individual ii-4 does not show any symptoms of the disease, it suggests that they either have two normal alleles (homozygous normal) or one normal allele and one disease allele (heterozygous).
Without knowing the genotypes of other family members or the prevalence of the disease in the population, it is not possible to determine the probability of individuals ii-4 being heterozygous for the disease allele. A genetic test or further analysis of the family pedigree would be needed to obtain more information and make a more accurate determination of the probability.
