The answer is true. Addiction is a chronic, often relapsing brain disease that causes over time challenge an addicted person's self-control and hampers his or her personality. Drugs are chemicals that tap into the brain’s communication system and disrupt the way nerve.
sulfites
propionic acid
benzoic acid
Answer:
Sulfites are thechemical food preservatives which used in the wine industry but may cause asthmatic reactions in some individuals .
Explanation:
A chemical food preservative is a chemical species which are added to a product such as the beverages , food , drugs , paints , wood etc , to prevent the process of degradation by microbes .
Sulfite is also an example of chemical food preservatives , sulfites helps the food from turning brown , in the presence of air .
Apart from helping the food from degrading , it too have same life - threatening symptoms for some people suffering from asthma .
Symptoms are - breathing difficulty , stomach cramps , tightness in the chest area , diarrhea .
Sulfites are used as a food preservatives in , wine , dried fruits , frozen potato , certain jams .
Answer:
0.01%
Explanation:
According to the ten percent rule of energy transfer, whenever energy is transferred from one trophic level to a higher trophic level only 10% of total energy available at the lower level gets transferred to a higher one.
Therefore, when the energy is transferred along with the food chain:
grass → grasshopper → mouse → snake → hawk, from grass to hawk there is a loss of 10% of energy at each level.
Therefore, the hawk only gets 0.01% of the energy from the grass.
Answer:
The best answer is Grass. The grass is photosynthetic, which means grasses make their energy from the sun. About 10% of this total energy is available to other organisms in the food chain.
Explanation:
B. oil in water
C. sand in water
D. all of these
Answer:
Nuclear Reaction
Explanation:
When two nuclei or particles move towards each other and, despite the Coulomb repulsion, they get close enough that there is interaction between the particles of one with the particles of the other by the nuclear force, and the formation of different particles and a redistribution of nucleons and a nuclear reaction is said to have occurred.
Nuclear reactions are usually produced by bombarding a target nucleus with a projectile that may be some type of particle or small nucleus, so that Coulomb's repulsion does not become a major obstacle. Reactions involving not very large energies occur in two phases. In the first phase, the target nucleus and the projectile group together, forming what is called a compound nucleus in a highly excited state. In the second phase, the composite core decays by any process that does not violate the conservation principles
-1 time
-2 times
- multiple times
Answer:
- multiple times
Explanation:
Blastopore is a term used in embryology to refer to an extremity that acts as a means of communication in the embryonic phase, bringing the digestive cavity into contact with the external one. The blastopore forms in the embryonic gastrula period, at which stage cell differentiation begins. Later, another extremity may arise, also during embryonic formation.
Depending on the group to which the animal belongs, this orifice may primarily perform the mouth function - as is the case with protostomies - or initially act as anus of the organism - in the case of deuterostomies.
In either case, we can say that throughout evolution the final detecting of blastoporos has changed several times.
How many times has blastopore fate changed over the course of evolution1 time
