The rigid layers of fungal cell walls contain polysaccharides called chitin and glucans. The wall protects the fungus from desiccation and predators. Most fungal hyphae are divided into separate cells by endwalls called septa(e). These tiny holes in the septa allow the rapid flow of nutrients and small molecules from cell to cell along the hypha.
Option A
Target organs regulate the pituitary through feedback loops. Most often, this takes the form of negative feedback inhibition.
<u>Explanation:</u>
Feedback inhibition is a cellular regulatory mechanism in which an enzyme’s action is frustrated by the enzyme’s terminal product. This method enables cells to control how much of an enzyme’s terminal product is created. An outstanding case of a negative feedback loop is detected in the regulator of thyroid hormone secretion.
To manage the discharge of chemical signals in the hypothalamus, pituitary glands Negative Feedback utilized widely. Negative feedback transpires when a product supplies back to reduce its creation. When the output of a way that constitutes restrains inputs to that way is recognized as Negative feedback
Answer:
2. Population is growing at its fastest rate
3. Population first reaches its carry capacity
4. Environment's carrying capacity declines
Explanation:
<h2>Gametophyte and Sporophyte Generations</h2>
Explanation:
- <em>The sexual stage, called the gametophyte generation,</em> produces gametes, or <em>sex cells, and the abiogenetic stage, or sporophyte age, </em>produces spores abiogenetically
- As far as chromosomes, the <em>gametophyte is haploid</em> (has a solitary arrangement of chromosomes), and the <em>sporophyte is diploid (has a double set)</em>
- All aquatic plants have alternation of generations. In mosses and their <em>family members (Bryophytes), the haploid gametophyte is the predominant age,</em> and the diploid sporophytes are sporangium-bearing stalks developing from the gametophytes
Answer:
Rattle snake, kit fox, coyote, raven
Explanation:
Secondary consumers form the third trophic level in a food chain or food web. They eat primary consumers which in turn eat the producers. An organism can have a different consumer level according to its position in the given good chain.
In the given food web; rattle snake, kit fox, coyote and raven eat many things simultaneously. However all of them also eat desert woodrat. Desert woodrat is a primary consumer since it consumes producer plants like creosote bush and beavertail cactus. Rattle snake, kit fox, coyote and raven are secondary consumers since they eat the primary consumer (desert woodrat). Desert iguana is not a secondary consumer. It directly feeds on creosote bush so it is a primary consumer.
