Rock Cycle Comic Strip Worksheet – Students learn about the different life cycles of various creatures. For example, a butterfly’s life cycle can be compared to the life cycle of a shark. They can also learn about the life cycle of an amphibian. This worksheet can help students learn how animals live. Students can complete the worksheet independently and as a class.
The life cycle of a human
Fertilization is the moment when an egg cell from a woman merges with a male sperm cell. This begins the human life cycle. On the sixth day, the single cell divides into a series of smaller ones that burrow into the mother’s womb. These cells form three layers and begin to bend into a complex shape called an embryo. They also start to differentiate and create the fetal nervous and circulatory systems.
The human body and brain undergo a number of changes during this time. While there are some differences between humans and apes in their lives, they all follow the same basic cycle. Apes, on the other hand, have a more erect body that allows them to show off their mobile hands. A human body and brain undergo a variety of changes after conception, which are supported by the food we eat.
The human life cycle is organized around a series developmental stages and age groups. It also includes an infant phase. A human’s average life expectancy is approximately seventy-eighty years. However, this can vary depending on their health.
The life cycle of a butterfly
The Life cycle of a butterfly begins with the butterfly’s egg. The caterpillar’s needs are met by the egg. Most butterflies lay eggs on leaves. The eggs are small and may be round, oval, or cylindrical in shape. Monarch butterflies lay their eggs on the underside of plant leaves. They can be either smooth or wrinkled. The eggs hatch within a few weeks.
Once the butterfly has emerged from the pupa, it pumps its blood into its wings. Within a few hours the wings will be fully developed and the butterfly can fly. Once the wings have grown, the butterfly will search for food and a mate. Once it has found a mate, it will lay eggs on a leaf.
The next stage is the adult stage. The butterfly lays eggs every year in spring, summer and fall. The female butterfly lays a large number of eggs at one time. Although the eggs are small, they can be very large. The egg is the basis for the development of the caterpillar (also known as the larva). During this time, it eats continuously and sheds its skin four or five times. It stores food for the adult butterflies.
Sharks live a long life
Sharks live a very long life span. Sharks can live up to 15 years. Sharks are most commonly born near the coast and stay close to their birthplace until they reach adulthood. During this time, sharks grow, mature, and reproduce. Sharks have two claspers, which allow them to grab onto a female and insert sperm.
The eggs and sperm are incubated by female sharks for several months before they reach full term. The young sharks remain inside the mother for a year and a half before they are born alive. Cannibalism is a behavior in which a shark’s first pup is alive and eats other pups or eggs. The gestation period of these ovoviviparous species varies, but it is often several months to two years. Asexual reproduction is also possible in some species.
Sharks are extremely sensitive to sound waves and have exceptional hearing. Their two sets of dorsal fins are located on either side of their heads. The lateral line system is made up of narrow canals filled with water that are attached to nerves that transmit signals to the brain.
Amphibian life cycle
Most amphibians have a complex life cycle, starting as a larva and ending as an adult. These life cycles are governed by hormones and the environment. Thyroid hormones and corticosteroids produced by interrenal glands are the primary morphogens in amphibians and are dependent on input from the hypothalamus and pituitary glands. The hypothalamus controls the activity of the thyroid and pituitary glands.
Amphibians are unique in their life cycles. They can reproduce in both water and on land. The life cycle of a frog begins with sexual reproduction, in which the male entices the egg-carrying females to mate. The females then release their eggs into the water where the males fertilize them with sperm. External fertilization is the most common method of reproduction for amphibians.
Many species of frogs lay eggs in calm water which protects them against predators. However, some species stay with the eggs to care for them. Once fertilized, the eggs begin to split into more cells, taking on the form of a tadpole. Within one to three weeks, the tadpoles are ready for hatching.
