List three examples of daily activities that affect homeostasis.
Tcecarenko [31]
<span>The three daily activities that affect homeostasis include;
Temperature, glucose levels, ability lymphatic system.
 Homeostasis is the tendency of organisms to auto-regulate and also maintain an internal environment within a stable state. The stable condition is when the optimal functioning of organisms and dependant on many variables.
 For example, fluid balance and body temperature to be kept within certain preset limits. PH of extracellular fluid, potassium, calcium ions and concentration of sodium and blood sugar levels are also variables.
 It is needed to be regulated despite the diet, environment, level of activities. They are controlled by homeostatic mechanisms which when comes together maintains life.</span>

DaniilM [7]

It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over spher
dangina [55]

Answer:

Genotypic ratio = 16 WwDd: 0

Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit

Explanation:

This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).

According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:

WWDD - WD, WD, WD, WD

wwdd - wd, wd, wd, wd

Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.

The genotypic ratio is 4 WwDd: 0

The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.
