Worksheet 11 Calvin Cycle 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. Students can also learn more about the life cycle and habits of amphibians. This worksheet can help students learn how animals live. The worksheet can be completed by students individually or in a group.
The 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 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.
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. 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.
Life cycle of a butterfly
The Life cycle of a butterfly begins with the butterfly’s egg. The caterpillar’s needs are met by the egg. 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 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. 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 next stage is the adult 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. The eggs may be small. 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 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. Most sharks are born in coastal areas and remain close to the area where they were born until they are fully grown. Sharks mature, reproduce, and grow during this period. 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 young sharks remain inside the mother for a year and a half before they are born alive. Cannibalism is a behavior in which a shark’s first pup is alive and eats other pups or eggs. The gestation period of these ovoviviparous species varies, but it is often several months 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. 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
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. 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 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. 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.
