Filetype Pdf Cycle Cell Pedigree WorksheetStudents learn about the different life cycles of various creatures. A butterfly’s lifecycle can be compared with that of a shark. They can also learn about the life cycle of an amphibian. This worksheet will help students understand how animals live. Students can complete the worksheet independently and as a class.

Life cycle of a human

The human life cycle begins at fertilization when the egg cell of a woman fuses with a sperm cell of a man. 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. In this stage, they also begin to differentiate from one another and form the fetal nervous system and circulatory system.

The human body and brain undergo a number of changes during this time. Although some differences exist between humans and apes, the basic life cycle of both is the same. 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. The average life span of a human is about seventy to eighty years, but this can vary widely depending on the health of the individual.

Life cycle of a butterfly

The egg is the first step in the life cycle of a butterfly. The caterpillar’s needs are met by the egg. Most butterflies lay eggs on leaves. The eggs can be small, round, oval or cylindrical. Monarch butterflies lay their eggs on the underside of plant leaves. They can be either smooth or wrinkled. Within a few weeks, the eggs will hatch.

After the butterfly emerges from its pupa, it injects its blood into its wings. After a few hours, the wings will fully develop and the butterfly will begin to fly. After the wings are fully developed, the butterfly will begin to search for food and a partner. Once it has found a mate, it will lay eggs on a leaf.

The adult stage is the next stage. The butterfly lays eggs every year in spring, summer and fall. A large number of eggs can be laid by a female butterfly at once. Although the eggs are small, they can be very large. The caterpillar, also known as the larva, develops from the egg. 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 have an extremely long life cycle. Sharks can live up to 15 years. Most sharks are born in coastal areas and remain close to the area where they were born until they are fully grown. Sharks mature, reproduce, and grow during this period. 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. These ovoviviparous species have a variable gestation period, which can vary from several months to up to two years. Some species are also known to reproduce through asexual reproduction.

Sharks are extremely sensitive to sound waves and have exceptional hearing. The dorsal fins on their heads are located on either side. 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

The life cycle of most amphibians is complex, with a larva becoming an adult and then a larva becoming a larva. Hormones and the environment control these life cycles. 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. A frog’s life cycle begins with sexual reproduction. This is when the male lures the egg-carrying women to mate. The females release their eggs into water, where the males fertilize with sperm. Most species of amphibians reproduce by external fertilization.

Many species of frogs lay eggs in calm water which protects them against predators. Some species, however, stay with the eggs to care. The eggs become tadpoles once they are fertilized. The tadpoles hatch within one to three weeks.
