Answer:
B. a fox
Explanation:
A secondary consumer is those that, to produce energy, consume primary consumers. Those are always herbivores or organisms that only eat autotrophic plants.
In this case, a rabbit and a cow are primary consumers.
The mouse is herbivores too.
The only option left is Fox.
Foxes eat other animals, they are carnivorous. This made the fox a secondary consumer.
b. a sepal.
c. a pistil.
d. a carpel.
B. negative feedback loop
C. constant feedback loop
b.Na+ and K+ leaks
c.Na+ cotransporter
d.Na+-K+ ATPase
The Na+-K+ ATPase, a membrane protein pump, prevents the sodium (Na+) and potassium (K+) gradients from dissipating by actively transporting these ions against their concentration gradients.
The mechanism that prevents the Na+ and K+ gradients from dissipating is the Na+-K+ ATPase. This is an integral membrane protein pump found in almost all animal cell membranes. This pump carries out the function of moving 3 sodium ions out of the cell and 2 potassium ions into the cell during each cycle of pumping. This is done at the expense of one ATP (adenosine triphosphate) molecule, hence the name ATPase. This active transport work against the concentration gradients of these ions, hence maintaining their respective gradients across the cell membrane.

True
Answer:
true
Explanation:
The answer is true.
b. division.
c. differentiation.
d. specialization.
The correct answer is c.
Differentiation in prenatal development is the process of growthand development in which embryonic cells become specialized and differenttissue structures rise. Differentiation of the cells during this stage is crucialto the cell, tissue, organ, identity of the organism.
