It's acellular. it's composed of all the proteins, electrolytes and micronutrients.
Weather – the condition of the outside air or atmosphere at a particular time and place.
Immunoassay is a process that can be used to detect a specific antigen or antibody present in a sample.
<h3>What are the various steps of immunoassay?</h3>
The various steps of immunoassay depends of the type of immunoassay used for diagnosis.
Using the direct Enzyme-Linked-Immunosorbent Assay (ELISA) the steps involved in antigen detection include:
- plate coating: the plate is coated with a known antibody
- plate blocking: Buffer is used to block free sites in the well.
- Antibody incubation is carried out at 37°C and
- Detection: Enzyme conjugated detection Antigen binds to the antigen.
Using the indirect Enzyme-Linked-Immunosorbent Assay (ELISA) the steps involved in antibody detection include:
- Micro-well plates are incubated with antigens, washed up and blocked with BSA.
- Samples with antibodies are added and washed.
- Enzyme linked secondary antibody are added and washed.
- A substrate is added, and enzymes on the antibody elicit a chromogenic or fluorescent signal.

Answer:
1. What is the relationship between body shape and the habitat where they are most commonly found?
2. What is the difference between toads having a thicker skin than frogs?
Explanation:
<u>Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics</u>. Among their main differences are:
- The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth.
- Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body.
- Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs.
- Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.
- Most toads are poisonous. In contrast in frogs, not all species are poisonous.
Given these observations, two questions that may arise could be:
1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.
2. What is the difference between toads having a thicker skin than frogs? Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.
Answer:
2) rough ER, transport vesicles, Golgi apparatus, transport vesicles, cell membrane
Explanation:
Insulin is a peptide hormone secreted by the pancreatic cells which are considered as the endocrine gland. Since the insulin is a peptide hormone, therefore, it follows the same path of secretion as other peptides follow.
The insulin peptide is produced by the ribosomes present on the endoplasmic reticulum. The insulin thus has to undergo certain modifications so the peptide is packaged in the transport vesicle and reaches the cis face of the Golgi apparatus.
There the peptide is modified and from there again packaged into the transport vesicles. The transport vesicles than reaches the cell membrane and fuse with the cell membrane and then released into the blood by exocytosis.
Thus, Option-2 is correct.
