Answer:
D
Explanation:
A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.
Information coming from each eye goes to the opposite-side thalamus, where "inter neurons" receive and help process signals from sensory neurons and shuttle the data to the visual cortex.
Explanation:
Interneurons are the fundamental nodes of neural circuits, allowing message transfer among sensory or motor neurons and the central nervous system (CNS). They show dynamic characters in reflexes, neuronal oscillations, and neurogenesis in the grown-up mammalian brain. Interneurons (also recognized as association neurons) are neurons that are found exclusively in the central nervous system. That means that they are found in the brain and spinal cord and not in the peripheral segments of the nervous system.
<span>The answer is d. Meiosis produces haploid cells, while mitosis produces diploid cells.
Meiosis begins with diploid cells but further divides into four daughter cells. Mitosis produces 2 diploid cells</span>
Answer:
proteins called expansins
Explanation:
The complete question is :
<em>According to the acid-growth hypothesis, auxin causes increased acidity in cell walls, which then activates ____ that disrupt(s) bonds between cellulose microfibrils, allowing cell expansion.</em>
<em>a. a membrane potential </em>
<em>b. an mRNA </em>
<em>c. AUX1 transporters </em>
<em>d. K+ ions </em>
<em>e. proteins called expansins</em>
<em></em>
- The acid growth hypothesis explains the growth of cells and organs in the plants.
- According to this hypothesis, the plant hormone auxin causes induction of the H+ proton extrusion into the apoplast which leads to the activation of expansin which a pH-sensitive protein.
- Expansin is responsible for wall stretching and relaxation and causes hydrolysis of hydrogen bonds and thus helps in cell expansion.
