The alternation of generations inthe life cycle of a plant includes the diploid and haploid multicellularstages. diploid and haploid are copies of the chromosomes. The spores in theplant is unicellular and when they start dividing through mitosis, it producesidentical cells. These identical cells are all haploid. Haploid stages containone set of chromosome from either of the parent. These identical cells create amulticellular system called the gametophytes. A gametophyte is the haploid multicellularstage in the life cycle of a plant. The gametophyte makes the gametes. These gametesare responsible for sexual fertilization. It takes place when a sperm (malegametes) from the male fuses into the egg cell (female gametes) of the female. The formation of both male and female gametes creates a diploidzygote. Diploid stages contain one set of chromosome from eachparent. This is where the sporophyte comes in. A sporophyte is the diploidmulticellular stage in the life cycle of the plant. It now contains the twosets of chromosomes from each parent.

Answer:

Photosynthesis does not occur in animal cells

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

• Lytic cycle

• Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.

Answer:

Species with a higher biodiversity (number of differences) will be more likely to survive environmental changes and pass those adaptations onto their offspring.

Explanation:

Natural selection is essentially the "survival of the fittest", so having a variety of organisms with their own adaptations may decrease the chances of them going extinct. If all organisms were the same, there would be very little biodiversity and (almost no) ability to fight change.
