Answer:
1. Please find the explanation to Part A below
2. Process 1 is meiosis while process 3 is cell division
3. Cells produced in process 1 are haploid while cells produced in process 3 are diploid
Explanation:
PART A:
The process 2 described in the attached image is called FERTILIZATION. It is the process whereby male gamete (sperm) unites with the female gamete (egg) to yield a ZYGOTE. This process of fertilization is important to sexual reproduction because it is the way the diploid state of an organism is restored after haploid gametes must have been formed via meiosis. In other words, haploid (n) sperm and egg unites during fertilization to yield a DIPLOID ZYGOTE (2n).
PART B:
- Process 1 in this attached image depicts MEIOSIS, which is the process whereby haploid daughter cells (gametes) are formed from the division of a diploid cell. Meiosis reduces the chromosome number of a cell by half.
- Process 3 is CELL DIVISION. The zygote formed from fertilization (process 2) undergoes series of cell division to produce the EMBRYO.
PART C:
The cells produced in process 1 (meiosis) are HAPLOID i.e. contains one set of chromosomes while the cells produced in process 3 (cell division) are DIPLOID i.e. contains two set of chromosomes
something like oil spills and volcanic eruptions are some disturbances that would create a primary succession situation in an ecosystem, because they essentially occur in lifeless areas
Answer:
B. a concept backed by many well-supported hypotheses
Answer:
D, All living things
Explanation:
Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
