Question

Write any two differences between the life cycles of humans and hens?

Answer 1

Answer:

,

Although both hatch from eggs, chickens and frogs experience different life cycles. Chicken eggs are fertilised internally and laid individually, while frog eggs are laid by the thousands and fertilised externally. Also, frogs endure stages of metamorphosis between hatching and maturity, while chickens do not.

Answer 2

Answer:

Concept :

In biology, a life cycle is the sequence of changes that individuals in a species go through as they transition from the start of one developmental stage to the start of that same developmental stage in an additional generation. In many basic organisms, such as bacteria and other protists, the life cycle is finished in a single generation: an organism starts by splitting into two new individuals, which completes the cycle. The life cycle starts with the fission of an existing individual.

Explanation:

• In backyard flocks, hens may live for 6–8 years, and the majority of flocks will lay eggs for 3–4 years. Each year, there is a decline in egg output, egg size, and shell quality.
• Most commercial layers are kept for two to three years because beyond that, their egg production starts to decline. Fertilization of the egg is stage 1. Egg Embryo, stage 2. 3rd stage: chick. Fourth stage: Pullet
• Higher animals also have a single generation in their life cycle, which includes the fusing of male and female sex cells (gametes), maturation into sexual maturity, and production of gametes, which kickstarts the cycle once more (assuming that fertilisation takes place).
• In conclusion, there are six primary phases in the human life cycle: foetus, infant, child, teenager, adult, and old. Although the stages of the human life cycle are described, humans constantly and progressively change throughout each stage.
