Some amphibians and crayfish can withstand periods of dryness by burying themselves in mud in pond that has muddy or silty areas

Amphibians and crayfish that can survive periods of dryness by burying themselves in mud would likely survive best in a pond that has muddy or silty areas, where they can burrow into the sediment to escape from drying conditions.

In order for these animals to survive, the pond should have sufficient mud or silt deposits that are moist and provide protection from desiccation. Additionally, the pond should not be too deep, as amphibians and crayfish need to be able to reach the surface to breathe air. The water level in the pond should also be stable, so that the animals do not become exposed during periods of low water.

It's important to note that while these animals can withstand periods of dryness, they still require a source of water to survive and breed, so a pond with consistent water supply would be ideal for their survival.

The correct sequence of applying immersion oil is as follows:

b. Focus on the specimen using the 40x objective lens.

c. Tum the objectives to halfway between the 40x lens and the 100x lens.

a. Apply a drop of immersion oil directly onto the area Of the slide you were viewing.

d. Rotate the 100x lens over the microscope slide, and use the fine focus adjustment knob to sharpen the image

The 100x objective lens with oil immersion is the most powerful light microscope lens. Immersion oil is used because it has been formulated in such a way the same refractive index as glass. Thus light refraction does not occur when moving from glass to oil and vice versa.

Here is the rule of conduct on immersion oil:

1. Focus on the colored sample at low power.

2. Alternate the turret 40x, centering the desired section of the sample. Refocus very carefully to get the sample in focus as sharply as possible. Keep using this focus for the next steps.

3. IMPORTANT STEP

Alternate the turret partly, so that 40x and 100x objectives stand on both sides of the sample.

Carefully, put a small drop of oil on the slide in the center of the bright area.

Be sure to set a drop of oil straight over the area of the sample to be tested.

4. Spin the turret and let the 100x oil immersion objective touches the oil and clicks into place.

Find the right focus by moving the slide slightly left and right. Always work with fine focus. Observe the motion in the visual field, and aim attention at the object which moved.

5. Place a drop of oil on the second sample, and smooth along the slide laterally until it is in place if you work with more than one sample on a slide.

6. After you have applied oil to the specimen, don't turn to the 10x or 40x objectives again, or else oil can ruin the lower power objectives.

7. After finishing with your observation, clean everything up by wiping the 100x oil immersion objective carefully. Use lens paper to remove all oil. For the slide, clean the oil thoroughly with lens tissue. Cleanse stage also in case oil has spilled on it. Close the immersion oil container tightly again, and put it back in the drawer.

Answer:

it’s S

Explanation:

The correct option is C) Exons are cut out before mRNA leaves the nucleus . Gene expression involves two major stages: transcription and translation.

Transcription involves the production of an mRNA molecule which is called a transcript. However, when this RNA transcript is newly made, it is regarded as pre-mRNA. It needs to undergo certain procedures collectively called RNA processing in order to be considered a mature RNA.

In an eukaryotic cell, pre-mRNA undergoes three major steps to become matured mRNA. These steps are:

1. Capping at the 5' end, which involves the addition of a nucleoside to the 5' end of the mRNA molecule.

2. Polyadenylation, which involves adding Adenine nucleotides to the 3' end of the mRNA molecule.

3. Splicing, which involves removal of the non-coding regions of the gene called EXONs from the coding region called INTRON. This process is carried out by an enzyme called SPLICEOSOMES.

RNA processing in eukaryotes occurs before the mRNA molecule leaves the nucleus for the cytoplasm in order to be translated. At the end of the RNA processing, the mature RNA molecule that leaves the nucleus is shorter than the pre-mRNA molecule due to the removal of exons during splicing.
