Fossils show that a group of organisms, such as marine mammals, have changed over time to adapt to different environments. 5. The environment will not select for or against organisms that have a particular structure unless that structure affects the organisms’ fitness. STRUCTURES AND FUNCTIONS a, youngest fossil; b, mammal fossils; c, first dinosaurs; d, first land plants; e, trilobites; f, oldest fossil Section 15-3 VOCABULARY REVIEW 1. the evolution of Caribbean anole lizards 2. Examples may include different breeds of dogs, cats, cattle, or food
d. Zach’s G.I. tract needs the substance to assist in the breakdown of food and for absorption. Epithelial cells extend into the lamina where they form secretory folds called gastric glands. Several of these glands open into the gastric pits and secretions from these glands flow into the pits. E. If Zach’s only normal digestive enzymes from his mouth, what
The kidney is surrounded by a capsule membrane, each of these membranes are topped by the conical adrenal gland. Both the kidneys and adrenal glands are coated in adipose tissue. Gross anatomy When the kidney is presented in a longitudinal section it displays an outer darker cortex and an inner paler medulla. The composition of the medulla is made up of cone shaped pyramids known as medullay pyramids, the tip of these cones are pointed into the area where the ureter connects the kidney. “The medulla is further divided into numerous sections called the medullary pyramids.”This region is known as the pelvis of the kidney.
Summary of “Why Evolution is true” By: Jerry A. Coyne What is evolution; chapter I explains Darwin’s theory of evolution, which applies to all species, new species are descended from earlier forms. This means that organisms with similar characteristics are likely to have shared a common ancestor sometime in the past. The more traits shared by organisms, the closer their evolutionary relationship. This principle of “common descent” explains why anthropologists are interested in studying nonhuman animals, particularly primates (the mammalian order that includes monkeys, apes, and humans), with whom humans share the closest common ancestor. Some of our important human characteristics, such as a spinal cord encased in a bony vertebral column, and the concentration of nerve cells in a brain, are part of our vertebrate heritage, established in a common ancestor over 600 million years ago.
According to the life history approach our entire lifecycle represents a series of trade-offs between allocating energy towards different life history traits using this idea of limited energy and trade-offs. Life history theory tries to answer the questions about the unique aspects of human development and lifecycle compared to other primates. Their life stages and their durations are compared to other species to identify where we are different and tries to explain why. Life history theory explains how natural selection and evolution work together for organisms to survive and reproduce in our ever changing environment. Life history theory looks at human lifespan stages through birth, infancy, childhood, reaching puberty, through reproduction stage, menopause, grandma stage and death.
The bulk of the pancreas is a ___________ gland. 217. What type of specialized cells are present in the pancreas to secrete pancreatic juice? 218. Where does the pancreatic duct lead to?
But a great deal of the experimental text in behavioral neuroscience originates from the study of animals not humans. Because of this a vital assumption in behavioral neuroscience came about. That assumption is that organisms share biological and behavioral similarities.. This associates behavioral neuroscience with comparative psychology, evolutionary psychology, evolutionary biology, and
This flattened part of the skull and the depressed region above the zygomatic arch constitute the temporal fossa which in life is occupied by the temporalis muscle. 1 6. ANS -B: The middle meningeal artery and accessory meningeal artery are branches of the max illary artery that enter the cranial cavity through foramen spinosum and foramen ovale. 1 7. ANS -B: The buccal branch of the facial nerve is the motor fo r the buccinator muscle.
The female reproductive system contains two main parts: the uterus, which hosts the developing foetus. The human female reproductive system is a series of organs primarily located inside of the body and around the waist. Fallopian tubes, uterus, cervix and vagina, as well as where they are located in the female body near the vagina. The male’s reproductive system is the penis and its male reproductive system is located outside of the man's body. The Fallopian tubes are a pair of long narrow tubes connecting the ovaries to the uterus.
