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

Gekata [30.6K]

Answer: See explanation below

Explanation:

Tributyrin agar Is the inability of this medium to distinguish between these different enzymes a weakness in its specificity or its sensitivity.

Lipases break down lipids (fats).

Tributyrin oil is a type of lipid called a triglyceride. Other lipase tests use different fat sources such as corn oil, olive oil, peanut oil, egg yolk, and soybean oil.

Lipase allows the organisms that produce it to break down lipids into smaller fragments. Triglycerides are composed of glycerol and three fatty acids. These get broken apart and may be converted into a variety of end-products that could be used by the cell in energy production or other process.

Tributyrin oil forms an opaque suspension in the agar. When an organism produces lipase and breaks down the tributyrin, a clear halo surrounds the areas where the lipase-producing organism has grown.

What happens to glucose produced by plants?
densk [106]

Answer:

Plants use cellular respiration to harvest the energy stored in the molecules

Explanation:

Plants, just like any other living organisms, need energy to power their cellular processes. Therefore plants also perform cellular respiration by burning energy molecules like glucose. The difference with plants, unlike animals, is that they make their own glucose from abiotic factors like sunlight and carbon dioxide.  They do this through the process of photosynthesis. Animals have to consume ready-made glucose that emanated (directly or indirectly)from plants.
