Answer:

Sonic Hedgehog.

Explanation:

Sonic hedgehog is a secreted protein that in humans is encoded by the SHH gene. It is the best studied ligand of the hedgehog signaling pathway, others being desert hedgehog (DHH) and Indian hedgehog (IHH). It plays a key role in the development of animals, from insects to mammals. In vertebrates, it is involved in organogenesis, including the growth of digits on limbs and the organization of the brain.

Sonic hedgehog has also been shown to act as an axonal guidance cue. It has been demonstrated that SHH attracts commissural axons at the ventral midline of the developing spinal cord. Specifically, SHH attracts retinal ganglion cell (RGC) axons at low concentrations and repels them at higher concentrations

STALIN [3.7K]

Answer:

multicellular.

Explanation:

Organisms exhibit various levels of organization of the body. It includes cellular level, tissue level, organ level, organ system level of organization. The unicellular organisms have single cells as their bodies and therefore do not have the genes that regulate the various parts of the body rather than the individual cells. Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.

Classify each statement as an example of adhesion, cohesion, or surface tension. Drag each statement to the appropriate bin. A s
LekaFEV [45]

Answer:

A sewing needle floats when it is placed gently on top of water in a bucket - surface tension

Water molecules ding to plant cell walls - adhesion

A water strider runs across a pond without breaking the surface - surface tension

A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface - cohesion

Water molecules cling to the side of a beaker - adhesion

Water molecules are attracted to each other - cohesion

Explanation:

The surface tension refers to the tendency of the surface of a liquid to remain unbroken by an external force due to the cohesive property of the molecules of the liquid. Instead of being broken, the surface of the liquid stretches like an elastic membrane.

The adhesive property of a liquid, also known as the force of adhesion, refers to the property of the molecules of the liquid to stick to other molecules while cohesive property or cohesion refers to the property of molecules of liquids to stick to themselves.

Hence,

<u>Surface tension</u>

  • A sewing needle floats when it is placed gently on top of water in a bucket.
  • A water strider runs across a pond without breaking the surface.

<u>Cohesion</u>

  • A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface.
  • Water molecules are attracted to each other.

<u>Adhesion</u>

  • Water molecules ding to plant cell walls
  • Water molecules cling to the side of a beaker
