Yes everyone deserves a second chance
Answer:
To absorb water to lowers the intensity of flood.
Explanation:
The main role of certain plant cells in flood control is to absorb water as well as the decrease the flow of water which slower down the intensity of flood. There are some plants in which their cells absorb huge amount of water which decreases the amount of water in the flood and as a result flood water decreases so that's why vegetation is very important in order to avoid flooded condition.
Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.
Answer:
16 possible combinations
Explanation:
Gamete formation involves the random and independent segregation of the alleles. During anaphase I (meiosis) occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.
The number of gametes with different combinations is 2ⁿ, where
n = number of homologous pairs.
In the exposed example there are 4 pairs of chromosomes, so
the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16
Answer: B) interference with new viral replication in preexisting cases
Explanation:
The herpes viruses are very important enveloped DNA viruses that cause disease in all vertebrate species and in some invertebrates such as oysters. Some of the human ones are herpes simplex (HSV) I and II, causing facial and genital lesions, and the varicella-zoster (VSV), causing chicken pox and shingles. Each of these three actively infect nervous tissue. Primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. The virus can then reactivate, replicate again, and be infectious to others.
If scientists are trying to use what they know about HSV to devise a means of protecting other people from being infected, which of the following would have the best chance of lowering the number of new cases of infection?
B) interference with new viral replication in preexisting cases.
