The description is provided in the explanation section below
Explanation:
ALTERNATION OF GENERATIONS is a unique phenomenon whereby certain organisms switch between a diploid state and a haploid state in their reproductive life cycle. It is a feature of plants (higher and lower).
A plant is a diploid organism (2n) i.e. contains two set of chromosomes. This diploid state of the plant is called the SPOROPHYTE. The diploid sporophyte (2n) of a plant undergoes meiotic division (reduction division) to produce haploid spores. These haploid spores germinates and grows via mitosis (duplication division) to form the haploid GAMETOPHYTE.
The haploid gametophyte (n), via structures called GAMENTAGIA, produces haploid gametes. The male gametophyte produces male gametes (sperm) while the female gametophyte produces female gamete (egg). These haploid gametes eventually fuse in a process called FERTILIZATION to produce a diploid ZYGOTE (2n) i.e. sperm (n) + egg (n) = zygote (2n). The ZYGOTE undergoes series of mitotic divisions (growth) to form the diploid SPOROPHYTE (2n) of the plant. The cycle restarts again in that order, hence it is called ALTERNATION OF GENERATIONS.
N.B: Mitosis maintains the number of chromosomes of the parent cell while meiosis reduces the chromosomal number of the parent cell by half.
The owl would have the least amount of energy from the producer. The higher the organism is on the food pyramid, the less energy it will receive from the producer. For example, if grass is a producer, it has the most energy. Then, if a bunny eats the grass, it takes a part of the grass’s energy but does not take all of the energy. Then, a wolf eats the bunny. The wolf gets a part of the bunny’s energy but not all. The wolf has received the least amount of energy from the grass.
The answer is: d. comparable in size to the heterosexual females
Simon LeVay is a neuroscientist that studies the relation of brain structure and sexual orientation. He examines the interstitial nucleus of anterior hypothalamic cells. The size of the nucleus in homosexual is found to be similar to women while the heterosexual male is much larger. The result doesn't enough to say that sexual orientation is genetic. This proves that there is the dimorphic nucleus in different sexual orientation.
Answer:
The main difference between diesel and petrol engines is that petrol engines use spark plugs to ignite the air-fuel mixture, while diesel engines rely solely on heavily compressed air.
