Asthma is due to spasms in the bronchi of the lungs making the task of breathing require more effort.
D. Lysogenic cycle. In this cycle, viral DNA is inserted into the host cell's DNA. It divides with mitosis, soon creating many infected host cells. Once the lytic cycle is triggered (usually from external factors), the viral DNA is transcribed/translated into viruses.
For the generalized scheme of Alternation of generations (see p. 120), plants have two forms based on a genetic complement that are the Sporophytes (2N diploid) and Gametophyte (N haploid). The processes connecting the two stages are gametangia producing haploid spores and zygote cell growth producing haploid gametophyte. Group of answer choices
Answer:
B
Explanation:
A zygote is the resulting cell from fertilization.
Fertilization occurs when the sperm (the male gamete/sex cell) fuses with the egg (the female gamete/sex cell). After they fuse, or fertilize, a cell forms that contains half of the DNA from the father (sperm) and the other half from the mother (egg). It has a complete set of DNA, and is considered a haploid cell.
It is not the structure that nourishes the fetus, an un-fertilized egg, or a ball of about 100 cells. Therefore, the correct answer is <u>B: a sperm fused with an egg.</u>
