Water Cycle Cloze Worksheet Answers – 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. 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
Fertilization is the moment when an egg cell from a woman merges with a male sperm cell. This begins the human life cycle. On the sixth day, the single cell divides into a series of smaller ones that burrow into the mother’s womb. These cells begin to form three layers and then bend into an embryo. They also start to differentiate and create the fetal nervous and circulatory systems.
The human body and brain undergo a number of changes during this time. 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. 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.
The life cycle of a butterfly
The Life cycle of a butterfly begins with the butterfly’s egg. 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 their eggs on the underside of plant leaves. They can be either smooth or wrinkled. Within a few weeks, the eggs will hatch.
Once the butterfly has emerged from the pupa, it pumps 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. It eats continuously during this period and sheds its skin up to 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. 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. 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.
Life cycle of an amphibian
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 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. 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. Once fertilized, the eggs begin to split into more cells, taking on the form of a tadpole. Within one to three weeks, the tadpoles are ready for hatching.
