b catalyze the assembly of amino acids into a protein
c carry genetic instructions for building a protein
Answers
Answer:
\(\boxed {\boxed {\sf A. \ Bring \ an \ amino \ acid \ to \ the \ ribosome}}\)
Explanation:
tRNA, or transfer RNA, plays an essential role in the process of protein synthesis (creation).
After DNA is transcripted and translated, the messenger RNA is created in the nucleus and sent to the ribosome. The mRNA has codons or sets of three nucleotides. Then, the tRNA enters. The tRNA has an amino acid (the monomer of proteins) and an anticodon (three nucleotides that are complementary to the mRNA).
The codon and anticodon create base pairs, and the amino acids attach to form a protein.
Based on this information, the best answer choice is A. bring an amino acid to the ribosome
In order to perform a soil microbial count on a sample of soil, you made an initial dilution by mixing 0.1g of soil in 10ml of sterile water then performed a serial dilution. You performed two additional 1:10 dilutions and plated 10 ul of the last two dilutions. By adding 0.1g of soil to 10ml of water, you generated a __initial dilution Which plate counts indicate improper technique took place during your dilution series? Choose a CORRECT answer for BOTH of the statements above
A. You generated a 10-2 initial dilution. Plate counts 171 and 25
B. You generated a 102 initial dilution. Plate counts 165 and 16
C.You generated a 10-initial dilution. Plate counts 252 and 25
D. You gerverated a 10-initial dilution Plate counts 312 and 29
E. You generated a 10-3 initial dilution Plate counts 111 and 11
Answers
The correct answer is B. The student generated a 102 initial dilution, and plate counts 165 and 16 indicate that improper technique took place during the dilution series.
To determine the initial dilution, we need to look at the dilution factor of the last two plates. The last two plates were both 1:10 dilutions, which means that they were both diluted by a factor of 10. Therefore, the initial dilution was 10 x 10 x 10 = 10^3 or 1000.
This means that the student added 0.1g of soil to 100ml of sterile water to make the initial dilution. Therefore, answer choices A, C, D, and E are all incorrect because they list incorrect initial dilutions. Only answer choice B lists the correct initial dilution of 10^2, but we also need to consider the plate counts.
Plate counts are the number of colonies that grow on the agar plates, and they can indicate whether there was too much or too little bacteria in the sample. Plate counts that are too high or too low can indicate that the student made a mistake during the dilution series.
In this case, the plate counts are 165 and 16, which is a difference of 10-fold. This means that there was a problem with the dilution series because there should not be such a large difference in the number of colonies between two consecutive dilutions. Therefore, we can conclude that improper technique took place during the dilution series.

what step can be skipped when preparing a specimen for light microscopy? question 8 options: the depth of a smear affects the results; if too thin you may find no organisms smears of culture media must be spread on the surface of a glass slide. wet mount preparations give good views of microbial mobility the specimen has to be heat fixed before being viewed in a hanging drop slide
Answers
When preparing a specimen for light microscopy, all steps are essential and skipping any one of them can result in suboptimal results.
For example, the depth of a smear affects the outcome of the microscopy, as a smear that is too thin may not contain enough organisms, while a smear that is too thick can cause overlapping of the organisms, making it difficult to distinguish individual cells.
Additionally, culture media must be evenly spread on a glass slide to ensure proper growth of the organisms and prevent clumping.
Wet mount preparations are essential for observing the movement of microorganisms, and heat fixing is necessary to preserve the morphology of the specimen and prevent it from washing away during the staining process.
Therefore, all steps in preparing a specimen for light microscopy are important and skipping any of them can compromise the quality and accuracy of the results. To obtain the most informative and accurate results, it is important to carefully follow all steps in the preparation of a specimen for light microscopy.

why are there different types of cells?(1 point) responses during mitosis, cells become specialized. during mitosis, cells become specialized. different types of cells have different chromosomes in them. different types of cells have different chromosomes in them. there are not different types of cells. there are not different types of cells. gene expression is different between different specialized cells
Answers
There are different kinds of cells because of differential expression of the genome. Meaning only the expression of some genes of the entire genome.
All the cells in an organism have the same genome. Cells of different stages and different lineages express different kinds of genes. This is due to factors like imprinting, effect of cellular signaling etc. A stem cell would not be expressing the entirety of the genome, it expresses genes that lead to synthesis of proteins like telomerase, as the cell differentiates, the telomerase synthesis is halted. If it were not so, the cell would be immortal. This is observed in some cancers.
Cells do not become specialized during mitosis. This process occurs during the G0 stage. Cells only divide then. And take up fates based on the environment and the cellular signals.
The cells having the same origin have chromosomes that are already present in the parent cell. In case of gametogenesis the cells may have different numbers of chromosomes and an anomaly, occurrence of mutations can change the number of chromosomes in a cell.
The cells of an organism share the same genetic content, which means they would have the same chromosomes, and do not undergo differentiation during mitosis. It is only after the division that the differentiation occurs. The cells of different specializations actually express different genes. This gives rise to different cell types in the body. An example is that secretion of insulin is only carried out in beta cells of pancreas.
Therefore, There are different cells due to different cells expressing different genes.

Answers
The thick band of neurons that connects the right and left cerebral hemispheres is called the corpus callosum.
The corpus callosum is a vital structure in the brain, as it allows for communication and coordination between the two hemispheres. It consists of approximately 200 million axonal projections, which are responsible for transmitting information between the left and right sides of the brain.
The corpus callosum plays a crucial role in integrating sensory, motor, and cognitive functions between the two hemispheres. This integration allows for the seamless functioning of various mental processes, such as language, memory, and problem-solving.
In some cases, individuals may be born without a corpus callosum (a condition called agenesis of the corpus callosum) or may have it surgically severed to treat epilepsy. These individuals can still lead relatively normal lives, although they may experience difficulties in tasks that require the integration of information from both hemispheres.
In summary, the corpus callosum is a vital brain structure that connects the right and left cerebral hemispheres, enabling communication and coordination between them. This integration is essential for the proper functioning of various mental processes, including language, memory, and problem-solving.

how can cardiac muscle tissue get sufficient rest
Answers
The cardiac muscle tissue get sufficient rest through few mechanisms in place to help it recover between contractions and maintain a steady rhythm:
DiastoleAutoregulationCoronary circulationSympathetic and parasympathetic nervous systemCardiac muscle tissue, also known as the heart muscle, has a unique characteristic compared to other types of muscle tissue in the body. Unlike skeletal muscle, cardiac muscle is responsible for continuously pumping blood and doesn't have the ability to fully relax and rest.
Diastole: During diastole, the heart relaxes and fills with blood. This phase allows the heart to recover and receive an adequate amount of oxygen and nutrients before the next contraction.
Autoregulation: Cardiac muscle has the ability to regulate its own blood flow, ensuring that it receives sufficient oxygen and nutrients even during periods of increased demand.
Coronary circulation: The heart has its own blood supply, known as the coronary circulation, which helps to ensure that the heart muscle receives an adequate supply of oxygen and nutrients.
Sympathetic and parasympathetic nervous system: The sympathetic and parasympathetic nervous systems play a role in regulating the heart rate and ensuring that the heart receives sufficient rest between contractions.
It is important to maintain a healthy heart and lifestyle to ensure that the heart muscle receives the rest and nutrients it needs to function properly. This can include regular physical activity, a balanced diet, and avoiding habits that can increase the risk of heart disease, such as smoking and excessive alcohol consumption.

When a chromosome undergoes a deletion mutation, information is? a.repeated
blost
c.reversed
d.transferred
Answers
When a chromosome undergoes a deletion mutation, information is lost. Option B is correct.
A deletion mutation is a type of genetic mutation in which a section of DNA is lost or deleted from a chromosome. This can occur due to errors in DNA replication, environmental factors, or other genetic mechanisms.
Deletion mutations can have a range of effects on gene expression and protein function, depending on the size and location of the deleted region. In some cases, the deletion may result in the loss of a single gene or a portion of a gene, which can affect the function of the protein encoded by that gene. In other cases, larger deletions may affect multiple genes and have more widespread effects on the organism's phenotype.
However, regardless of the specific effects of a deletion mutation, the fundamental consequence of this type of mutation is the loss of genetic information from the affected chromosome.

D. hydrophilic.
E. used as transport channels.
Answers
Membrane proteins are not very soluble in water because they possess long stretches of non-polar amino acids that are hydrophobic.
Membrane proteins are proteins that are embedded within or associated with the lipid bilayer of a cell membrane. They play important roles in various cellular functions, including transport, signal transduction, and cell-cell interactions.
The lipid bilayer of cell membranes is composed of hydrophobic fatty acid tails that interact with each other and exclude water, and hydrophilic phosphate heads that interact with water. The hydrophobic regions of membrane proteins, which are often composed of non-polar amino acids like alanine, leucine, and phenylalanine, interact with the hydrophobic fatty acid tails of the membrane and are excluded from the aqueous environment.
In contrast, the hydrophilic regions of membrane proteins, which often contain polar or charged amino acids, interact with the hydrophilic environment of the cytosol or extracellular fluid. Therefore, the correct answer is B. hydrophobic.

biologists stocked a lake with 300 fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be 10000. the number of fish doubled in the first year.
Answers
In the first year, the number of fish doubled from 300 to 600. Since the carrying capacity of the lake is estimated to be 10,000, there is still room for more fish to reach the maximum population. To determine the number of fish in the second year, we need to calculate the rate at which the fish population is increasing.
The rate of increase is found by dividing the difference between the carrying capacity and the current population by the current population. In this case, it is
(10,000 - 600) / 600 = 16.67.
Now, to find the population in the second year, we multiply the current population by the rate of increase. So,
600 * 16.67 = 10,002 fish.
Since this is a continuous growth model, the population will continue to increase each year. However, it will eventually reach a point where the rate of increase will start to slow down as it approaches the carrying capacity.

Answers
Your blood's force against your artery walls is measured as blood pressure. Your heart pumps blood into the arteries with each heartbeat. If your heart is beating and pumping blood, your blood pressure will be at its highest.
How blood pressure increases or decreases?
The aorta has the highest blood pressure in the general circulation, while the vena cava has the lowest blood pressure. This implies that when blood travels from the aorta to the rest of the body, blood pressure decreases in the general circulation. The aorta releases pressure into the arteries, which release pressure into the arterioles, which release pressure into the capillaries. Before blood starts to collect in the venules, capillary flow rate hits a minimum. The venules, veins, and vena cavae all continue to lose pressure.Lowest mean pressure
