First image is Correct. DNA probes are single-stranded DNA lengths that can be used to detect the presence of target sequences through hybridization.

In order to be detected, DNA probes are typically labeled, for instance with radioisotopes, epitopes, biotin, or fluorophores. A single-stranded DNA or RNA sequence used as a probe is one that is used to look for its corresponding sequence in a sample genome. In order for the probe sequence to hybridize with its complementary sequence, the sample and probe must be in touch.

A single-stranded DNA or RNA sequence known as a probe is used to identify particular DNA or RNA sequences. They are made to be complementary to the relevant region of the genome so that when the probe and the genome are combined, this will happen.

The limitations of the body mass index as a measure of body size is it cannot measure lean body mass.

BMI or body mass index is a calculation obtained by dividing body weight by height. This measurement serves to determine a person's ideal body weight and nutritional status. After doing BMI, we can find out whether we are overweight, normal, or underweight.

To calculate body mass index, you can use the formula: Body mass index (BMI) = body weight (kg) : height (m). Everyone's BMI results can be different depending on age, gender, ethnicity and others. Although it can determine a person's weight and nutritional status, BMI has limitations, namely it cannot measure lean body mass or how much fat is in the body.

Answer:

Weather

Explanation:

The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.

When we talk about climate change, we talk about changes in long-term averages of daily weather. Today, children always hear stories from their parents and grandparents about how snow was always piled up to their waists as they trudged off to school. Children today in most areas of the country haven't experienced those kinds of dreadful snow-packed winters, except for the Northeastern U.S. in January 2005. The change in recent winter snows indicate that the climate has changed since their parents were young.

If summers seem hotter lately, then the recent climate may have changed. In various parts of the world, some people have even noticed that springtime comes earlier now than it did 30 years ago. An earlier springtime is indicative of a possible change in the climate.

In addition to long-term climate change, there are shorter term climate variations. This so-called climate variability can be represented by periodic or intermittent changes related to El Niño, La Niña, volcanic eruptions, or other changes in the Earth system

The rates of protein production, the folding speeds of its slowest proteins, and—for big cells—the rates of protein diffusion all serve as growth constraints on cells.

The surface-area-to-volume ratio of cells prevents cells from growing to an extent that their surface area is insufficient to absorb nutrients and expel waste.

Prokaryotic cells do not fit the criteria for the cell hypothesis since they lack a distinct nucleus. Every known living thing is made up of one or more cells. All living cells grow from pre-existing cells through division. The cell is the fundamental structural and functional unit in all living things.

The loss of the cystic fibrosis (CF) gene in a population is most likely to be caused by natural selection against the CF allele.

Cystic fibrosis is a genetic disease caused by a mutation in the CFTR gene. People with cystic fibrosis experience a range of symptoms, including respiratory problems and digestive issues, which can reduce their life expectancy.

The severity of the symptoms can vary, but on average, individuals with cystic fibrosis have reduced reproductive fitness compared to individuals without the disease.

In this scenario, natural selection against the CF allele is likely to occur because individuals with the CF allele are at a disadvantage in terms of reproductive fitness. Over time, the frequency of the CF allele in the population is likely to decrease as individuals with the CF allele are less likely to survive and reproduce compared to individuals without the disease.

Proteins are polymers formed of structural units called c)amino acids.So,correct option is c.

Proteins are polymers, meaning they are enormous particles comprised of numerous more modest atoms. The little particles that make up proteins are called amino acids.Every amino corrosive contains a carbon particle, an amino gathering, a carboxyl gathering, and a side chain (otherwise called a R bunch).

The side chain is the main variable part of the amino corrosive. The kind of side chain distinguishes the sort of amino corrosive and furthermore decides its qualities (for example its size, pH, and extremity). There are around 20 distinct kinds of amino corrosive in the human body, however these can join to make roughly 20,000 extraordinary proteins.

Amino acids are consolidated by peptide bonds, which structure between the amino gathering of one particle and the carboxyl gathering of another. Two amino acids combined is known as a dipeptide; a chain made of different amino acids is known as a polypeptide.

After translation, proteins are not immediately functional upon creation. They are not completely finished and usable by the cell, and must go through further modifications such as folding and processing before they can function properly. Therefore, the description "They are not completely finished and usable by the cell" is true.

The correct description of proteins after translation is that they are not completely finished and usable by the cell, which is the third option, as during the process of translation, they often require additional modifications.

During transcription, the DNA sequence of a gene is copied into an RNA molecule, which is then used as a template for translation, in the process of translation, the ribosome reads the RNA sequence and uses it to assemble a specific sequence of amino acids into a polypeptide chain, and the most important modification that proteins undergo after translation is folding, proteins must fold into specific three-dimensional shapes in order to function properly.

The most likely explanation for a lack of change in a species over a 5,000-year time period is that the species is well-adapted to its environment and experiences little pressure to evolve.

Evolution by natural selection occurs when certain traits that are advantageous in a particular environment become more common in a population over time. If a species is well-adapted to its environment, it may not experience much pressure to evolve, as the traits that are advantageous in its environment are already common in the population.

In this case, the species in question has likely been able to survive and reproduce effectively for thousands of years without undergoing significant changes, as it is well-adapted to its environment.

If a species experiences no significant environmental changes over a long period of time, it may not experience pressure to evolve and may remain relatively unchanged.

The de novo synthesis of nucleotides is a complex process that involves the synthesis of purine and pyrimidine nucleotides separately and their subsequent combination with ribose or deoxyribose to form the final nucleotides. Therefore, option C is the correct statement about de novo synthesis of nucleotides.

Nucleotides are the building blocks of DNA and RNA, which are essential for genetic information storage and transmission. De novo synthesis of nucleotides refers to the process of synthesizing nucleotides from simple precursor molecules rather than using pre-existing nucleotides. In this process, purine and pyrimidine nucleotides are synthesized separately and then joined together to form nucleotides.

The correct statement about de novo synthesis of nucleotides is option C - purines are synthesized and then attached to ribose or deoxyribose. Purines are synthesized from small molecules like amino acids, carbon dioxide, and formate, in a complex process involving multiple enzymatic steps. The final product, inosine monophosphate (IMP), is then converted to AMP and GMP, the two purine nucleotides. These nucleotides are then combined with ribose or deoxyribose to form the final purine nucleotides, adenosine and guanosine.

On the other hand, pyrimidines are synthesized from smaller molecules like aspartate, carbamoyl phosphate, and bicarbonate. The end product of pyrimidine synthesis is uridine monophosphate (UMP), which is then converted to the other pyrimidine nucleotides, cytidine and thymidine.
