Africa, Australia, etc because they are the oldest ones.
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
Answer:
<em>The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.</em>
Answer:yo B I think
Explanation:
Cuz evolution is a slow process and it takes time and A dont make any since
Answer:
1) Stem cells can renew themselves by dividing into more stem cells more than once.
2) There are two types of stem cells: adult and embryonic stem cells.
3) Stem cells are not specific to one area in the body and can turn into skin, bone, blood or brain cells.
