Answer:
Innate immunity is a nonspecific defense mechanisms that play its role as soon as an antigen appear in the body (it is relatively rapid but nonspecific and because of that it is not always effective)
Explanation:
The barries of innate immunity are:
Skin: At Epidermal surface, its protective aspect are keratinized cells that lives on the surface, known as Langerhans cells.
Skin sweat or secretions: Their specific defense is sweat glands and sebaceous glands, and their protective aspect is low ph and washing action.
Mucosal surfaces: they are at the mucosal epithelium, and their protect aspects are nonkeratinized epithelial cells.
Oral cavity: They defend salivary glands through Lysozyme
The term microclimate best describes the area around the pond.
<h3>What is Pond?</h3>
A pond may be defined as an aquatic habitat which is a tiny body of still water originated naturally or by artificial norms. It is usually smaller than a lake.
A microclimate may be defined as a climate of a small area or a distinct place within a location as distinguished from the surroundings of the complete area.
A microclimate usually involves a very smaller area in contrast to determining the climate of a particular location.
The complete question is as follows:
The area around the pond is cooler than the rest of the forest. Which term describes the area around the pond?
- Biome
- Microclimate
- Macroclimate
Therefore, the correct option for this question is B, i.e. microclimate.

The correct answer is (c) metastasis.Metastasis is the spreading of tumor cells to distant parts of the body (from one organ to another, that is not even directly connected with it) via blood and lymph. When the doctor says that the cancer is metastatic, it means the cancer cells are spreading and can be dangerous.
Answer:
sieve-tube elements, companion cells
Explanation:
Sieve-tube elements and companion cells are responsible for the movement of photosynthes through a plant.
The sieve tube elements are shorter (almost organelle-free) living cells, placed end to end, forming the sieve tubes. Their transverse cell walls are called sieve plaques that make connections between cells and through openings called sieves establish the connection between the cytoplasm of adjacent cells. Each sieve is coated with calose (glucose polymer), which in winter can completely clog the vessel and then dissolve in spring. When infections occur or the vessel is parasitized, it can also be clogged with callose.
Companion cells are specialized parenchymal cells, which contain all the components that exist in living cells, including the nucleus, are the cells most closely linked to the sieved tube element. The Screened Tube Element and its companion cells are related in development, are derived from the same mother cell, and have several cytoplasmic connections to each other. Due to the many connections, the potential function of the companion cells is to release substances into the sieved tube element and, when the nucleus is absent, to include information molecules, proteins and ATP. When a screened element dies, its companion cells also die, which is a demonstration of this interdependence.
Answer:
Transition
Explanation:
Secondary succession occurs when the existing vegetation is removed by some disturbances and soil is already present in the region to support the growth of new species. During succession, the early species are being replaced by later successional species.
In the given example, the forest has patches of early species and later species. This means that the forest is in the transition period of succession where early species were not completely replaced by the new species. Once the early species will be removed and the climax community develops, the forest has reached the final stage of succession.
