Bumble Bee Life Cycle Worksheet – Students are taught about the life cycles of different 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.
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. The sixth day is when the single cell splits into several smaller cells that burrow into the mother’s womb. These cells begin to form three layers and then bend into an embryo. In this stage, they also begin to differentiate from one another and form the fetal nervous system and circulatory system.
During this period, the human brain and body undergo many changes. Although some differences exist between humans and apes, the basic life cycle of both is the same. For example, humans develop an erect body and show off their movable hands, whereas apes develop great cognitive talents. A human body and brain undergo a variety of changes after conception, which are supported by the food we eat.
A human life cycle is structured around a series of 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. This egg contains the nutrients the caterpillar needs to survive. Most butterflies lay eggs on leaves. The eggs are small and may be round, oval, or cylindrical in shape. Monarch butterflies lay eggs on the undersides of plant leaves. They may be smooth or wrinkled. The eggs hatch within a few weeks.
After the butterfly emerges from its pupa, it injects 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. Once it has found a mate, it will lay eggs on a leaf.
The next stage is the adult stage. The butterfly lays eggs 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). It eats continuously during this period and sheds its skin up to five times. It stores food for the adult butterflies.
Life cycle of a shark
Sharks live a very long life span. They can live for up to fifteen 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.
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. Some species of sharks exhibit cannibalism, where the first pup is born alive and eats other eggs or pups. These ovoviviparous species have a variable gestation period, which can vary from several months to up 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. 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
Most amphibians have a complex life cycle, starting as a larva and ending as an adult. Hormones and the environment control these life cycles. The primary morphogens of amphibians are thyroid hormones and corticosteroids, which are produced by interrenal cells. They are dependent on inputs from the hypothalamus as well as the pituitary and pituitary. 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 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.
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.
