The correct answer is 2, 1, 4 because in meiosis II, the stages are similar to mitosis. In prophase II, the nuclear envelope breaks down, the chromosomes condense, and the spindle fibers form. In metaphase II, the chromosomes line up at the equator of the cell. In anaphase II, the sister chromatids separate and move towards opposite poles of the cell. Therefore, the correct order of these stages is 2 (prophase II), 1 (metaphase II), and 4 (anaphase II).

The correct answer is "pembuatan DNA rekombinan" because it refers to the process of creating a new DNA molecule by combining genetic material from different sources.

Based on the given information that the patient's urine reacted positively to the biuret and benedict reagents, the most likely disorder that occurred is damage to the glomerulus. The biuret reagent is used to test for the presence of proteins, and a positive reaction suggests that there is an abnormal amount of protein in the urine, which can be a sign of glomerular damage. The benedict reagent is used to test for the presence of reducing sugars, and a positive reaction suggests that there is an abnormal amount of sugar in the urine, which can also be a sign of glomerular damage. Therefore, the correct answer is kerusakan pada glomerulus.

The correct answer sequence for the osmosis experiment on plant cells is hipotonis – isotonis – hipertonis. In this experiment, the cells are placed in different solutions with varying concentrations. Hipotonis solution has a lower solute concentration than the cells, causing water to enter the cells and making them swell. Isotonis solution has the same solute concentration as the cells, resulting in no net movement of water. Hipertonis solution has a higher solute concentration than the cells, causing water to leave the cells and making them shrink.

To maintain the productivity of the forest, it is necessary to balance the logging activities with reforestation efforts. By cutting down trees in a sustainable manner and replanting new trees, the forest can continue to thrive and provide various benefits such as timber, oxygen production, and habitat for wildlife. This approach ensures that the forest remains productive while also minimizing the negative impacts of deforestation.

The given question describes a cross between two mango plants with different characteristics. The first plant has small sweet fruits (MMkk) while the second plant has large sour fruits (mmKK). When the F1 generation undergoes self-pollination (autogamy), the resulting offspring will have a combination of the traits from the parent plants. Since the trait for sweet taste (M) is dominant over the trait for sour taste (m), all the offspring will have sweet fruits. The question asks for the number of mango fruits with sweet taste, regardless of their size. Since the total number of offspring is 320, and all of them have sweet taste, the answer is 240.

Apabila bunga dengan genotip AaBB disilangkan dengan bunga bergenotip aaBb, maka tidak akan ada anakan dengan bunga warna merah yang muncul. Hal ini disebabkan oleh fakta bahwa gen AaBB menghasilkan antosianin yang menghasilkan warna merah, sedangkan gen aaBb tidak menghasilkan antosianin. Oleh karena itu, semua anak bunga yang dihasilkan dari persilangan ini akan memiliki genotip AaBb, yang tidak menghasilkan antosianin dan akibatnya tidak akan memiliki warna merah.

The correct answer is nonkompetitif, where the inhibitor molecule binds to a site other than the active site of the enzyme. In noncompetitive inhibition, the inhibitor molecule binds to a different site on the enzyme, known as the allosteric site, causing a change in the enzyme's shape and preventing it from functioning properly. This type of inhibition is not reversible and cannot be overcome by increasing the concentration of the substrate.

The correct answer is 5 - 3 - 4. This is because the process of translation involves the translation of the genetic code from RNA to protein. In this process, the RNA molecule (specifically mRNA) is read by the ribosome, and the sequence of nucleotides is translated into a sequence of amino acids. This is represented by the steps 5 (process of translating the genetic code), 3 (formation of a polypeptide chain), and 4 (formation of a polypeptide). Therefore, the correct order is 5 - 3 - 4.

The correct answer is "restriksi, memisahkan basa Nitrogen dengan basa Nitrogen lainnya." Restriksi adalah enzim yang digunakan dalam rekayasa genetika untuk memotong atau memisahkan DNA pada tempat-tempat tertentu. Enzim ini bekerja dengan mengenali urutan-urutan tertentu dalam DNA dan memotongnya. Dalam konteks pembuatan hormon insulin, enzim restriksi digunakan untuk memotong DNA pada tempat-tempat tertentu sehingga fragmen-fragmen DNA yang mengkode polipeptida utama insulin dapat diisolasi dan digunakan untuk menghasilkan insulin.

When a plant with genotype KkLl undergoes autogamy (self-fertilization), there are four possible genotypes that can be obtained in its offspring. This is because each parent plant can contribute one of two alleles (K or k) for the first gene and one of two alleles (L or l) for the second gene. Therefore, the possible combinations are: KKLL, KkLL, KKll, and Kkll. Hence, there are four different genotypes that can be obtained.

Since the woman is normal and her father is albino, it means that she carries the albino gene but does not express it. The man she is marrying is normal and does not have a history of albino in his family. Therefore, none of their children will inherit the albino gene from both parents, resulting in 100% normal children.

The correct answer is vi, elang. The highest trophic level in the given energy flow diagram is occupied by the eagle (elang). This means that the eagle is at the top of the food chain and consumes organisms from lower trophic levels.

Sebelum menentukan hipotesis, langkah yang sebaiknya dilakukan adalah membuat rumusan masalah tentang konsentrasi pupuk urea yang paling tepat untuk pertumbuhan jagung. Hal ini penting karena rumusan masalah akan membantu dalam menetapkan tujuan penelitian dan mengarahkan penelitian agar lebih fokus dan terarah. Dengan membuat rumusan masalah, peneliti dapat memperoleh pemahaman yang lebih baik tentang apa yang ingin diteliti dan mengapa hal tersebut penting untuk diteliti.

When the egg is placed in a 25% sugar solution, it will shrink because the water inside the egg will move out through osmosis. Osmosis is the movement of water molecules from an area of lower solute concentration (inside the egg) to an area of higher solute concentration (the sugar solution). This causes the egg to lose water and shrink in size.

The answer states that if a leaf covered with carbon paper reacts positively to iodine (lugol), it means that there is starch (amilum) present. This explanation suggests that the carbon paper acts as a barrier that prevents the leaf from undergoing photosynthesis and producing starch. Therefore, if the leaf still shows a positive reaction to iodine, it indicates that starch was already present in the leaf before the experiment.

The correct answer includes options 1, 2, 6, and 7. These options mention events that are considered as genetic mutations. These events include an increase in the number of nitrogen bases, an increase in loci/segments, the insertion of nitrogen bases, and the occurrence of crossing over. These events can lead to changes in the genetic material and can result in genetic variations within a population.

Not using the land for a certain period after harvest can help improve soil fertility in the area. This is because giving the land a rest allows it to naturally replenish its nutrients and regain its fertility. By not using the land immediately after harvest, the soil has time to recover and restore its nutrient levels, which can ultimately improve the fertility of the soil in the area.
