Answer:
The life process may be defined as the different process that are important for the sustenance of life. The most important life process are nutrition, respiration, excretion and transportation.
If the mouse is placed in the closed sealed container then the weight will remain before and after the experiment of 1 or 2 week. This is because the life process metabolic reactions will use and conserve all the atoms involved in the life process. These atoms can exist in the liquid, solid and gas forms but present inside the container.
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. The gases are the fundamental cause of the greenhouse effect. Increase in the amount of greenhouse gases in the atmosphere enhances the greenhouse effect which is creating global warming and consequently the climate change. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries. .
Animals and plants get rid of carbon dioxide gas through respiration. Carbon may also move from fossil fuels to the atmosphere when fuels are burned. Burning of fuels to power factories, power plants, cars and trucks makes carbon to enter the atmosphere as carbon dioxide.
For spindle fibers to pull the chromatids towards opposite poles
Answer:
Neural crest cell movements are inhibited.
Explanation:
Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.
Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.
Thus, the answer is neural crest cell movements are inhibited.
There are numerous advantages and disadvantages that selective breeding has on food crops. A few of the advantages are; the creation of high quality products, provides a sustainable food chain, eliminates disease and creates new varieties of food crops. A few disadvantages of selective breeding on food crops are; no control over genetic mutations, brings discomfort to animals, creates offspring with different traits, and poses some environmental risks.
