Substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.
<h3>In which two ways do substances cross the membrane?</h3>
The selective passage of substances across the membrane occurs in two different ways:
- active transport, when it involves the use of energy.
- passive transport, when it does not involve the use of ATP.
With this information, we can conclude that substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

<span>The crossed flies are heterozygous so they have one allele of each for the characteristics. So the genotype is Bb for body color and Rr for eye color.
To set up the punnett square, you would determine all possible combinations for the alleles that each parent could provide: BR, Br, bR, and br. Then make the table, and combining the rows and columns:
BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
There are sixteen combinations of the genotypes and they need to be classified: BB or Bb- Brown body; bb- black body; RR or Rr- red eyes; rr- brown eyes
Brown body and red eyes- 9
Brown body and brown eyes- 3
Black body and red eyes- 3
Black body and brown eyes 1</span>
Answer:
Diseases that result from a homeostatic imbalance include heart failure and diabetes, but many more examples exist. Diabetes occurs when the control mechanism for insulin becomes imbalanced, either because there is a deficiency of insulin or because cells have become resistant to insulin.
- diabetes
- Blood oxygen content homeostasis.
- Homeostatic Imbalances of the Blood
- Plasma ionized calcium homeostasis.
- Arterial blood pressure homeostasis.
- Core body temperature homeostasis.
- The volume of body water homeostasis.
- Extracellular sodium concentration homeostasis.
