How do heredity and environment determine characteristics of an organism through controlled breeding?

By selectively breeding individuals with desired traits, heredity controls the passing down of specific genes from parent to offspring. Environment influences how these genes are expressed through factors like diet, exercise, and exposure to external stimuli, shaping the development and expression of an organism's characteristics. Controlled breeding can help to isolate and study the relative impact of heredity and environment on an organism's traits.


What dye is used in a vital stain?

A vital stain is a dye that is utilized to selectively stain living cells without affecting their viability or function. Common dyes used for vital staining include trypan blue, propidium iodide, and calcein-AM. These dyes can help distinguish between live and dead cells in various biological assays.


What allows potassium to diffuse in and out of cells?

Potassium diffuses in and out of cells through potassium channels, which are membrane proteins that selectively allow potassium ions to move down their concentration gradient. These channels help maintain the resting membrane potential and are crucial for many cellular processes, including nerve signaling and muscle contraction.


What stops cytoplasm from leaking out across the plasma membrane?

The plasma membrane is a selectively permeable barrier made of phospholipids that prevents cytoplasm from leaking out. Additionally, the presence of cellular junctions, such as tight junctions in animal cells, help to maintain the integrity of the plasma membrane and prevent leakage of cytoplasmic contents.


How do cell use both diffusion and osmosis to help maintain homeostasis?

Cells use diffusion to passively transport small molecules like gases and ions across their membrane based on the concentration gradient. Osmosis, a specific type of diffusion, involves the movement of water molecules across a selectively permeable membrane to balance water potential. Together, diffusion and osmosis help cells maintain internal balance by regulating the flow of substances in and out of the cell to ensure a stable internal environment.

How goes having cells with walls help a leaf to absorb as much energy as possible?

Cell walls, unlike cell membranes, are not selectively permeable. Less energy would be able to leave the cells.

What do DNA Profiling and Captive Breeding programs to help Tasmanian Devils?

DNA profiling can help determine the particular genes which are active in the deadly cancer cells. This inturn can help scientist find a cure for the disease. Captive breeding ensure that there are a population of healthy devils which can be sustainably released into the wild.

What is one medically relevant use of the deadly compound ricin?

Ricin has been used for medical research in cancer treatment due to its ability to inhibit protein synthesis, which can help target and destroy cancer cells selectively.


What time of year do chickens set on the eggs?

Chickens typically set on eggs in the springtime, as this is their natural breeding season. The longer days and warmer temperatures during the spring months help to create favorable conditions for incubating eggs.
