Answer:
First, it's important to get clear on the meaning of Homeostasis.
In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.
Explanation:
In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.
This does not mean that the plant or animal is completely immune to such external changes.
In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.
Cheers!
Macromolecules or large particles are carried across the cell membrane via vesicles or other intracellular structures. Pinocytosis and efflux are the two types of vesicle transport.
<h3>How does a vesicle leave the cell with its cargo?</h3>
Exocytosis is the process by which cells move components from within the cell to the extracellular fluid. Exocytosis occurs when a vesicle's plasma membrane fuses with it, expelling its contents outside the cell.
The Golgi, also known as the Golgi complex, is a flattening, layered organelle that looks like a stack of pancakes. The Golgi body modifies and packages proteins and carbohydrates into lattice vesicles for "exportation" from the cell.

Yes, but only if the chromosomes are paired in the right ways. tetrad development in late prophase.
<h3>How does DNA function? Why does it matter?</h3>
The biological instructions that give each species its distinctiveness are found in a substance known as deoxyribonucleic acid (DNA). Adult organisms reproduce by transmitting their DNA and the genetic information it carries to their progeny.
<h3>What is the purpose of a person's DNA?</h3>
Genes, which are a component of DNA, are the building blocks of all living organisms. DNA's capacity for recurrent self-replication is its most significant property. DNA must be replicated in order to create new cells, convey genetic information from one generation to the next, and act as a code for the RNA (ribonucleic acid) needed to make proteins.

Answer:
Occurrence. In primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to "normalize" the habitat. Primary succession begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil.
