Lytic Cycle Worksheet Answers – Students learn about the different life cycles of various 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 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. 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 infancy period. 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.
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 can be small, round, oval or cylindrical. Monarch butterflies lay eggs on the undersides of plant leaves. They may be 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. 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 next stage is the adult 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. 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.
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. Sharks mature, reproduce, and grow during this period. 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. The gestation period of these ovoviviparous species varies, but it is often several months to two years. Asexual reproduction is also possible in some species.
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
Most amphibians have a complex life cycle, starting as a larva and ending as an adult. 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 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. 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.
