Cell Cycle Mitosis Diagram 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. 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. 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. The food we eat supports a host of changes in the human body and brain after conception.
The human life cycle is organized around a series 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. This egg contains the nutrients the caterpillar needs to survive. Most butterflies lay their eggs on leaves. The eggs can be small, round, oval or cylindrical. Monarch butterflies lay eggs on the undersides of plant leaves. They can be either 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. 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 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 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. 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. Sharks have two claspers, which allow them to grab onto a female and insert sperm.
Female sharks incubate the eggs and sperm for a period of several months until they reach full term. The mother keeps the young sharks inside for about a year before they are born. 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 have excellent hearing and are able to detect incoming sound waves from their prey. 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. 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.
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. Within one to three weeks, the tadpoles are ready for hatching.
