what the number and variety of different species in a given area?

some caddisfly larvae make cases to live in and some make nets to catch prey in the water is true.

Trichoptera, an order of aquatic insects, includes caddisfly larvae. To shield themselves from predators and create a stable environment for their growth, certain species of caddisfly larvae build cases around their bodies. Sand, gravel, twigs, leaves, silk, and other materials can all be used to create these cases.

Other caddisfly larvae species make nets out of silk that they use to catch small aquatic critters for sustenance. The caddisfly larva waits inside these nets, which are often fastened to a solid substrate like rocks or plants, waiting for food to become trapped.

Answer:

it’s S

Explanation:

Organisms are able to interact with each other in a way that keeps the ecosystem going.

Ecological interactions among organisms refer to the ways in which different species in an ecosystem interact with each other and with their physical environment. These interactions can be grouped into several categories, including:

Predation: One organism (the predator) kills and eats another organism (the prey).

Herbivory: An organism (the herbivore) feeds on plants.

Competition: Two or more organisms compete for the same limited resources such as food, water, or mates.

Mutualism: A relationship in which both species benefit from their interaction with each other.

When exposed with the protein blot stain, the cortex, a form of ground tissue, transmits proteins to the nitrocellulose membrane without the action of peroxidase (Ponceaus S).

The main role of peroxidases in plants is to cross-link the phenolic residues of cell wall glycoproteins and polysaccharides to impart stiffness and strength to the cell wall. Furthermore, plant peroxidase was found to be involved in lignification. A technique used to detect peroxidase activity in various regions of plant tissue is known as tissue printing. Most of the peroxidase activity in plant tissues studied by this technique is restricted to regions such as the epidermis, hypodermis, metaxillum, phloem, and mature outer cortical cells. For roots, peroxidase activity was found to be absent in cortical tissue or cortex and meristem regions.

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.

Steroids, also known as corticosteroids, have a complex effect on the healing process. While they can have some benefits, they can also have some negative effects. Here option C is the correct answer.

Speeds up the primary union are partially true. Steroids have been shown to have a positive effect on the formation of a primary union, or the initial stage of healing, by reducing inflammation and swelling. This can help to reduce pain and increase mobility in the affected area.

Speeds-up healing is also partially true. Steroids can help to reduce inflammation and swelling, which can in turn speed up the overall healing process.

Inhibits healing is also partially true. While steroids can have some positive effects on the healing process in the short term, long-term use of steroids can have a negative effect on the healing process. Steroids can interfere with the production of new cells and tissues, which is necessary for the body to repair and heal itself.

Overall, the effect of steroids on the healing process is complex and depends on the duration and dose of the steroid treatment, as well as the underlying health of the individual.

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.

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.
