Chicken pox is a virus that causes an itchy rash but typically does not have any major or lasting effects on an infected person.

Before 1995, chicken pox parties were popular. In a chicken pox party, healthy children were brought around children who were sick with chicken pox so that they would be exposed to the virus and their immune system would learn to fight it. A vaccine for chicken pox was developed in 1995, and chicken pox parties are now rare. What best describes how vaccines have advanced science? Vaccines are more effective on ethnicities that are highly susceptible to a disease. Vaccines can determine which genes can cause disease. Vaccines can minimize lifestyle choices that allow for greater exposure to a disease. Vaccines allow for building immunity without harmful exposure because not all viruses are safe to be exposed to

An organism that reproduces sexually has a diploid number of 30. How many
Strike441 [17]

Answer:

Gamete of organism has a haploid number of chromosomes.

2n = 30

n = 15

A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.

After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Nocturnal animals are important pollinators. What niche do they
Shtirlitz [24]

Answer:

C. They pollinate the flowers that only open at night.

Explanation:

A niche is the functional role an organism performs in the ecosystem. Simply, the question is asking for the role of nocturnal animals as pollinators.

  • A pollinator is any organism the helps plants to transfer pollen grain from the anther of one flower to the stigma of another.
  • This way, fertilization and crossing of genetic materials is achieved.

Nocturnal animals are animals that are very active at night. This is an evolutionary advantage for them because there is less danger at this point of the day.

Therefore, some nocturnal animals can help to pollinate flowers that only open at night.

I temperature will continually rise until it melts assuming you do not stop applying heat to the ice. It doesn’t really matter at what temp below freezing you start as long as you go above freezing the ice will melt.
