Answer:
C, recycle, but if I could choose two it would be reuse.
Reasoning:
Reusing things and recycling things are both useful for the community.
1. a quantity of water: Liter
2. the length of a leaf: Meter
3. the mass of a small stone: Gram
Having the occasional alcoholic drink is unlikely to affect your fertility. But heavy drinking and smoking can reduce sperm quality, lower testosterone production, and make it harder to achieve an erection. It can also lead to liver damage, which affects both your general and reproductive health
<h2>Autocrine signaling </h2>
Explanation:
In autocrine signaling,signal acts on same cells which produce them
- Sonic Hedgehog helps in cell growth and development
- Hedgehog signaling pathway plays an essential role during vertebrate embryonic development
- Sonic hedgehog has particularly marked roles in nervous system cell type specification and limbs patterning
- Activation of sonic hedgehog pathway can happen in two major ways:
- Canonical signaling: by ligand-dependent interaction or through receptor-induced signaling
- Non-canonical signaling:when there’s a mechanism of activation downstream of smoothened
- The sonic hedgehog canonical signaling occurs when the glycoprotein sonic hedgehog binds and inactivates the 12-transmembrane protein Patched
- In the lack of the ligand sonic hedgehog, the activity of the 7-transmembrane protein smoothened is inhibited by patched so sonic hedgehog protein binding patched regulates smoothened activity
- The non–canonical activation occurs through Gli-independent mechanisms and it can be of two types
- Type I which modulates Ca2+ and actin cytoskeleton
- When sonic hedgehog binds the receptor patched, smoothened is no longer inhibited and couple Gi proteins (G) and small GTPases RhoA and Rac1 activated
- Type II is the one which is independent on smoothened
- When smoothened binds patched, the interaction of patched with cyclin B1 is disrupted, leading to an increase in cell proliferation and survival
