Answer:
Generally, aquaporins are found in the membranes of plants and also in the membranes of animals. It is a transporter, which takes part in mediating or regulating the flux of water across the membranes. A cell expresses the aquaporin protein due to many factors:
1. They function as sensors of gradients in turgor pressure and osmotic potential.
2. Aquaporins can assist in regulating and maintaining water permeability in response to different stresses like salt, drought, chilling, and others as water can move at a much greater speed through aquaporins.
3. Aquaporins can help in the movements of carbon dioxide, H2O2, NH3 through the plasma membrane briskly. Thus, the expression of aquaporin is essential for various species.
Answer:
The best answer to the question: The Z disc forms the end____ of a sarcomere, would be: the end border, or the point where sarcomeres join, within a muscle fiber.
Explanation:
Concretely, a Z disc is the boundary line that divides sarcomeres within a muscle fiber. They are the bordes between sarcomeres and they contain the most important molecule, actin, which forms the thin filaments essential for muscle tissue movement. This actin molecule, present along the Z discs, under the correct stimulation and circumstances, will bind to myosin and thus movement will be possible.

Answer:
Tall offsprings: 13/25
Short offsprings: 12/25
Explanation:
According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:
13 tall pea offsprings
12 short pea offsprings
This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.
That is;
Tall offsprings: 13/25
Short offsprings: 12/25
In percentage, this can be represented as:
Tall offsprings: 13/25 × 100 = 52%
Short offsprings: 12/25 × 100 = 48%
