Name That Cycle Worksheet Answers – Students are taught about the life cycles of different 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. The worksheet can be completed by students individually or in a group.
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 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. For example, humans develop an erect body and show off their movable hands, whereas apes develop great cognitive talents. The food we eat supports a host of changes in the human body and brain after conception.
A human life cycle is structured around a series of developmental stages and age groups. It also includes an infancy period. A human’s average life expectancy is approximately seventy-eighty years. However, this can vary depending on their health.
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 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. Within a few weeks, the eggs will hatch.
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 adult stage is the next 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 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 have an extremely long life cycle. 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 mother keeps the young sharks inside for about a year before they are born. 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. The dorsal fins on their heads are located on either side. 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. 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. 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. 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.
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. The tadpoles hatch within one to three weeks.
