When is cell-to-cell communication particularly important in regulating gene expression?

Cell-to-cell communication is particularly important in regulating gene expression during the embryonic development.

Cells in the developing embryo are constantly communicating with their neighbors. The molecules used by them in sending and receiving signals are crucial for normal embryogenesis. Various intracellular signaling pathways have been discovered, some of which are activated in response to secreted growth factors.

However, a few important signaling pathways are used often during embryonic development to regulate various cellular processes that shape the developing embryo.

Embryonic development is marked by the thorough regulation of cellular functioning so that the cells proliferate, migrate, differentiate, and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, as well as on the activities of signaling pathways, which coordinate the cell interactions leading to organogenesis.

The Punnett square shows a cross between two parents. The allele (H) represents the mutated gene that causes Huntington’s diseas
Lelu [443]

Answer:

The disease is autosomal dominant.

Explanation:

Huntigton's disease is an autosomal dominant disease because the allele for this disease is present on an autosomal chromosome and the person with even one mutated allele (H) can develop the disease even if he has one normal allele (h) too. If a person is affected with Huntigton's disease, there are 50 percent chances that the children will also suffer from the disease.


For example: A father is suffering from Huntigton's disease but mother is normal. Let us see how it will be passed to kids.


P1:                                   Hh :           hh

Gametes:                         H :         h:      h:       h

Offspring:                         Hh:       Hh:      hh:        hh

                                               50%        :       50%

Therefore, 50 percent chances are there that the kids will have disease even if only parent suffers from it.

Does sustainability cause environmental pollution in plants
gladu [14]

Answer:Environmental pollution is any discharge of material or energy into water, land, or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth's ecological balance or that lowers the quality of life. Pollutants may cause primary damage, with direct identifiable impact on the environment, or secondary damage in the form of minor perturbations in the delicate balance of the biological food web that are detectable only over long time periods.

Air pollution is the process which the substances and the energy forms are not present in normal atmospheric composition reach the atmosphere, or are present but in much lower concentrations.Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.

More than 3,000 substances that are not part of the atmospheric composition, falling in the atmosphere can be considered air pollutants.

Some substances that are normally present in the atmosphere in a certain concentration can be considerate pollutants because their concentration is much higher than usual concentration.

Also certain substances that are normally present in certain layers of the atmosphere (e.g. ozone in the stratosphere), once arrived in the troposphere is pollutant.

Some gases, such as oxides of nitrogen may have beneficial effect on vegetation, after hydration may affect the leaf fertilizer.

The air pollutants factors can be chemical (chemicals), mechanics (particles in suspension) physical (ionizing radiation) and acoustic (noise).
