Darkling Beetle Life Cycle 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. Students can also learn more about the life cycle and habits of amphibians. This worksheet can help students learn how animals live. The worksheet can be completed by students individually or in a group.
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. The sixth day is when the single cell splits into several smaller cells 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.
During this period, the human brain and body undergo many changes. 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 egg is the first step in the life cycle of a butterfly. The caterpillar’s needs are met by the egg. Most butterflies lay their 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. After the wings are fully developed, the butterfly will begin to search for food and a partner. After finding a mate, the butterfly will lay eggs on a leaf.
The adult stage is the next stage. The butterfly lays eggs in spring, summer, and fall. A large number of eggs can be laid by a female butterfly at once. The eggs may be small. 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 also stores food, which will be used by the adult butterfly.
Life cycle of a shark
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. Two claspers allow sharks to grasp onto females and insert sperm.
Female sharks incubate the eggs and sperm for a period of several months until they reach full term. The young sharks remain inside the mother for a year and a half before they are born alive. Some species of sharks exhibit cannibalism, where the first pup is born alive and eats other eggs or pups. The gestation period of these ovoviviparous species varies, but it is often several months to two years. Some species are also known to reproduce through asexual reproduction.
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. Their lateral line system consists of thin canals filled with water and is attached to nerves that send 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. 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. Ultimately, the hypothalamus regulates the activity of both the thyroid gland and the pituitary gland.
Amphibians have unique life cycles and a unique ability to reproduce in two environments – on land and in water. 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. Most species of amphibians reproduce by external fertilization.
Most species of frogs lay their eggs in peaceful water, which protects them from predators. However, some species stay with the eggs to care for them. The eggs become tadpoles once they are fertilized. Within one to three weeks, the tadpoles are ready for hatching.
