Frogs are amphibians that are known for their jumping abilities, croaking sounds, bulging eyes and slimy skin. They live all over the world and are among the most diverse animals in the world, with more than 6,000 species.
Frogs substantially outnumber the two other groups of amphibians — salamanders and caecilians. According to the American Museum of Natural History (AMNH) online reference site, Amphibian Species of the World, which is updated in real time, as of late April 2015, there are 6,482 species in the Anura order (frogs and toads), 691 species in the Caudata order (salamanders and newts) and 204 species in the Gymnophiona order (caecilians). Caecilians look like large worms or slick snakes, according to the San Diego Zoo. They have no arms or legs, and live underground in a network of tunnels.

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
A Trombe wall (Trombe rhymes with prom, by the way) is a wall that warms trapped air, and then circulates it to help heat a house. Trombe walls are ideally made out of a material with a fairly high thermal mass materials (like bricks or concrete), and are often painted black to improve heat conduction
The answer is homozygous dominant
Answer:
$ {[Co{(en)_2}C{l_2}]^ + } $ Has largest number of isomers which include both geometrical as well as optical (cis and Trans). It includes stereoisomers which have d isomers, I isomers, and optically inactive form of isomers. So D is the correct option
