A dog was hit by his previous owner, and now the dog cowers each time his new owner reaches out to pet him.

Answers
The example of sensitization from the given alternatives is that 'A dog was hit by his previous owner, and now the dog cowers each time his new owner reaches out to pet him.'
Sensitization refers to the process in which an organism becomes more sensitive to stimuli, both good and bad. It happens when the body's nervous system becomes oversensitized to a particular stimulus that it begins to respond even to weaker or non-threatening stimuli.
The example given in the first option refers to a simple reflex action that occurs in response to the puff of air that is blown into the eyes during the eye examination. The third option is about sensory adaptation, which occurs when sensory receptors are exposed to stimuli for an extended period, resulting in a reduction in sensitivity. The fourth option refers to the fight or flight response that occurs as a result of a threatening stimulus, in which an individual's body prepares to confront or flee from danger.

Answers
Answer:
The geosphere is made up of all the rocks and minerals on or below Earth's surface.
The outer part of the geosphere is called the crust, which forms the land we live on as well as the ocean bottom.
The hot rock beneath this layer is known as the mantle and includes the uppermost lithosphere as well as the softer asthenosphere.
As this layer moves, it drags large sections of lithosphere, called tectonic plates and is made up of molten and solid metals.
Explanation:
The geosphere is the layer of the Earth that includes all the rocks and minerals found on or below its surface. It is one of the four major components of the Earth's system, along with the atmosphere (air), hydrosphere (water), and biosphere (living things). The geosphere is the solid, rocky part of the Earth, and it includes the Earth's core, mantle, and crust.
The outer part of the geosphere is called the crust. The Earth's crust is the thin, outermost layer of the geosphere, and it is what forms the land we live on, as well as the ocean floor. The crust is composed of several types of rocks, including igneous, sedimentary, and metamorphic rocks.
The hot rock beneath the crust is called the mantle. The mantle is the layer of the Earth that lies directly beneath the crust and is composed of hot, dense rock. The mantle is divided into two parts: the uppermost lithosphere, which is rigid and brittle, and the softer asthenosphere, which flows more easily.
As the mantle moves, it drags large sections of the lithosphere, which are called tectonic plates. These plates are made up of the Earth's crust and the uppermost part of the mantle, and they can move relative to one another. The movement of tectonic plates is responsible for many geological phenomena, such as earthquakes, volcanoes, and the formation of mountains.

What are the factors that may limit the distribution & abundance of a species? (Choose all that are correct.) a. Limitation by physical-chemical factors b. Biological interactions w/ other species c. Dispersal ability
Answers
Physical and chemical variables can restrict the spread and abundance of species. Here option A is the correct answer.
Limitation by physical-chemical factors: Physical and chemical factors such as temperature, rainfall, pH, soil composition, and nutrient availability can directly affect the survival, growth, and reproduction of a species. For example, certain plants may have specific soil pH requirements, and if those conditions are not met, their distribution may be limited.
Biological interactions with other species: Interactions with other species, including competition, predation, parasitism, and mutualism, can greatly impact a species distribution and abundance. Competition for resources like food, water, and territory can limit the range of a species, while predation and parasitism can reduce its population size.
Dispersal ability: The ability of a species to disperse and colonize new areas can significantly influence its distribution. Species with limited dispersal abilities, such as those restricted to a specific habitat or with limited mobility, may have restricted distributions. Dispersal can be influenced by factors like reproductive strategy, the presence of barriers (e.g., mountains, bodies of water), and the availability of suitable habitats.

Answer:
Co-Dominance
Explanation:
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.

A brown cow and a white cow have a baby. The baby cow is white with brown spots. The baby cow is a result of co-dominant offspring.
The universal loss of mass seen in the skeleton, which begins about the age of 40 ________.
A) is slower in females than in males
B) is absolutely uniform throughout the skeleton
C) reflects incomplete osteon formation and mineralization
D) is greater in African Americans than in Northern Europeans
Answers
The universal loss of mass seen in the skeleton, which begins about the age of 40 option C) reflects incomplete osteon formation and mineralization.
What is osteoporosis?
As we age, our bones undergo a natural process of losing mass and density, which is known as bone loss or osteoporosis. This process begins around the age of 40 and is characterized by incomplete osteon formation and mineralization, leading to a decrease in bone strength and an increased risk of fractures.
The rate of bone loss may vary between individuals, but it is generally slower in females than in males. It is also not absolutely uniform throughout the skeleton, as certain areas may experience more rapid bone loss than others. Ethnicity can also play a role in the rate of bone loss, with some studies suggesting that African Americans may have a higher risk of osteoporosis than Northern Europeans.

What is the hypothalamic-pituitary ovarian?
Answers
The hypothalamic-pituitary-ovarian (HPO) axis is a complex system that controls the release of reproductive hormones in females. It is made up of three main parts: the hypothalamus, the pituitary gland, and the ovaries.
The hypothalamus is a small region of the brain that is responsible for regulating many of the body's functions, including hormone release. It releases gonadotropin-releasing hormone (GnRH) which stimulates the pituitary gland to release two hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
The pituitary gland is located at the base of the brain and is responsible for producing and releasing a number of hormones that regulate various bodily functions. FSH and LH are two of these hormones that play a key role in regulating the menstrual cycle and ovulation in females.
The ovaries are a pair of reproductive organs located in the female pelvis. They produce estrogen and progesterone, which are responsible for the development of the female reproductive system and the regulation of the menstrual cycle. The ovaries also release eggs during ovulation.
The HPO axis is regulated by a feedback system, where the levels of estrogen and progesterone produced by the ovaries influence the release of FSH and LH by the pituitary gland. This, in turn, influences the release of GnRH by the hypothalamus. This complex system ensures that the ovaries release eggs at the appropriate time and that the menstrual cycle proceeds as it should.
Overall, the HPO axis is a crucial system that plays a vital role in the regulation of the menstrual cycle and ovulation in females. It coordinates the release of hormones from the hypothalamus, pituitary gland, and ovaries to ensure that the female reproductive system functions properly.

In this process, lactate produced by muscles during anaerobic respiration is transported to the , where it is converted to glucose via gluconeogenesis. The newly synthesizedliver glucose is then released into the bloodstream and transported to other tissues for energy production.
The liver also plays a significant role in the transport of nutrients, hormones, and drugs into the circulatory system. It metabolizes and detoxifies harmful substances and converts them into forms that can be excreted by the body. Additionally, the liver is responsible for synthesizing plasma proteins, including albumin and clotting factors, which are essential for maintaining homeostasis in the body. The liver also stores and releases glucose, vitamins, and minerals into the bloodstream, regulating the levels of these nutrients in the body. Overall, the liver plays a critical role in maintaining the proper functioning of the circulatory system.
