what developmental characteristics distinguishes a fetus from an embryo? at what gestinal age is this attained
The answer is that the developmental characteristic that distinguishes a fetus from an embryo is the formation of distinct organ systems.
At this stage, the developing organism is able to carry out vital functions such as breathing, digestion, and excretion. This stage is usually attained around the end of the eighth week of gestation.
During the embryonic stage, the developing organism undergoes rapid cell division and differentiation, giving rise to the basic structures and tissues of the body. At this stage, the organism is called an embryo and is characterized by its primitive streak, which eventually becomes the neural tube, and its three germ layers: ectoderm, mesoderm, and endoderm.
As development progresses, the embryo undergoes a series of complex changes, including the formation of major organ systems such as the heart, lungs, liver, and kidneys. This stage of development is referred to as the fetal period, and the developing organism is called a fetus.
By the end of the eighth week of gestation, the fetus has formed all major organ systems and is able to carry out basic functions such as breathing, digestion, and excretion. It is at this stage that the organism is considered to be a fetus rather than an embryo.

an individual hormone affects only certain tissue cells called its __________ cells.
An individual hormone affects only certain tissue cells called its target cells.
Target cells have specific receptors that recognize and bind to the hormone, triggering a response within the cell. This selective response allows for precise communication between hormones and their target tissues, ensuring that only the necessary physiological processes are stimulated.
Red blood cells with the look of a shooting target with a bullseye are known as codocytes or target cells. These cells appear to have a white outside ring (an area of relative pallor) surrounding a dark inner (central) hemoglobinized area, followed by a dark outer (peripheral) second ring. On the other hand, they appear incredibly thin and bell-shaped under an electron microscope, therefore their name. They are known as leptocytes because of how thin they are. Some people like to differentiate between leptocytes and codocytes based on the morphology of routine smears, arguing that in leptocytes the central spot is not entirely isolated from the peripheral ring and that the pallor is in the shape of a C rather than a whole ring.

List three types of bone cells and it’s function during ossification
The three types of bone cells are osteoblasts, osteocytes, and osteoclasts.
1) Osteoblasts are responsible for bone formation during the initial stages of ossification. These cells synthesize and secrete the organic matrix of bone tissue, which includes collagen fibers and other proteins. Osteoblasts also mineralize the organic matrix by depositing calcium and other minerals, leading to the formation of new bone tissue.
2) Osteocytes are mature osteoblasts that have become trapped within the mineralized bone matrix. They play a crucial role in maintaining bone tissue by regulating the deposition and resorption of minerals. Osteocytes communicate with other bone cells and respond to mechanical stress by signaling the formation of new bone tissue.
3) Osteoclasts are large, multinucleated cells that are responsible for bone resorption. They break down old or damaged bone tissue by secreting enzymes that dissolve the mineralized matrix. Osteoclasts are necessary for bone remodeling, as they create space for new bone tissue to form and help maintain bone density.

glucose is stored in muscles and the liver in the form of group of answer choices glycogen. triglycerides. nitrogen. glucagon.
Glycogen, a form of glucose storage, is found in the muscles and liver.
In animals, glucose is stored as a complex carbohydrate called glycogen. It is created and kept in the muscles and liver, where it may be quickly changed back into glucose as needed.
Glycogen is the appropriate response to the question of how glucose is stored in the liver and muscles.
The body needs glucose as a source of energy. To keep blood sugar levels steady, the body must control glucose levels. In the liver and muscles, extra glucose is stored as glycogen. Glycogen is converted into glucose and delivered into the bloodstream when energy is required.
Each branch of the highly branching polymer of glucose molecules that makes up glycogen contains several glucose subunits. About 100 grams of glycogen are stored in the liver; this glycogen can be converted to glucose and released into the bloodstream to regulate blood sugar levels. On the other hand, during activity, muscle glycogen is predominantly used to produce energy. Glycogen is not released into the bloodstream even though muscle tissue stores significantly more of it than the liver does.
In conclusion, glycogen, a type of glucose, is stored in the liver and muscles. When required, this complex carbohydrate can be swiftly broken down into glucose to act as a reserve energy source.

ppm as used in this laboratory exercise, is not normally used in plant tissue culture research. why might this not be generally for plant tissue culture research? g
In a laboratory exercise involving plant tissue culture research, the term "ppm" (parts per million) is used to indicate the concentration of a substance in a solution. However, ppm may not be commonly used in plant tissue culture research for several reasons.
First, plant tissue culture research often involves working with cells, tissues, or organs in vitro, and requires precise control of the chemical and physical environment. The concentrations of nutrients, growth regulators, and other substances are typically expressed in molar units, such as millimolar (mM) or micromolar (µM), as these units facilitate easier calculation and understanding of chemical reactions and interactions.
Second, the sensitivity of plant tissues to various substances can vary significantly depending on the species, tissue type, and growth conditions. Expressing concentrations in ppm might not provide the desired level of accuracy or precision required for some experiments. Molar units allow for a more precise representation of concentration, ensuring that the conditions can be accurately replicated and controlled throughout the research process.
Finally, using molar units instead of ppm also aids in the standardization of methodologies and results across different research studies. This standardization facilitates more effective communication among researchers and enables easier comparison of results obtained from various experiments.
In conclusion, while ppm is a unit of concentration, it might not be commonly used in plant tissue culture research due to the need for precision, sensitivity, and standardization in experimental conditions. Instead, molar units such as mM or µM are often preferred for these studies.

during which phase of karyokinesis (mitosis) do duplicated chromosomes separate? group of answer choices anaphase metaphase
During phase of karyokinesis (mitosis) do duplicated chromosomes separate anaphase, option A.
The term "anaphase" refers to the stage of mitosis that follows the process of metaphase, when replicated chromosomes are divided and the newly-copied chromosomes (daughter chromatids) are transferred to opposing poles of the cell. The word anaphase comes from the Greek roots "ana-" for "backward" and "phásis" for "appearance." In late anaphase, chromosomes also reach their overall maximum condensation, which helps with chromosomal segregation and the re-formation of the nucleus.
Anaphase is considered to have started when the inhibitory chaperone securin is ubiquitylated by the anaphase-promoting complex. The protein securin inhibits a protease known as separase. Securin's degradation releases separase, which subsequently degrades cohesin, the protein that holds sister chromatids together.
Sister chromatids are drawn towards the poles by kinetochore microtubules as the centromeres divide. As they are drawn to either pole, they assume a V-shape or Y-shape. Interpolar microtubules and astral microtubules provide forces that stretch the cell into an oval shape as the chromosomes are dragged to each side of the cell.

The process by which natural selection produces a divergence in traits and resource use among sympatric species is called __________________ displacement
The process by which natural selection produces a divergence in traits and resource use among sympatric species is called character displacement.
When two species occupy the same geographic location, they often compete for the same resources. Over time, natural selection favors individuals that are better adapted to utilize a particular resource, and this selection pressure can lead to a divergence in traits and resource use among the two species.
Character displacement is an important mechanism of evolutionary change, as it can promote the coexistence of different species in the same habitat by reducing competition. For example, in the Galapagos finches, two species of finches with similar beak sizes coexist on the same island, but they have different diets. When they are on different islands, the species have different beak sizes, but when they share the same island, their beak sizes converge. This is an example of character displacement, as natural selection has favored different beak sizes to reduce competition for resources.
Overall, character displacement is a fascinating process that plays a critical role in shaping the diversity of life on Earth. It highlights the power of natural selection to produce and maintain differences among species and provides important insights into the mechanisms that underlie the coexistence of multiple species in the same ecosystem.

The presence of a third layer of smooth muscle assists the continued _______ and blending of the ______
The presence of a third layer of smooth muscle assists the continued propulsion and blending of the food bolus.
Smooth muscle is found in the walls of many internal organs, including the digestive tract. In the digestive system, it is primarily responsible for the involuntary contractions that move food through the tract, a process known as peristalsis. The third layer of smooth muscle is especially important in the stomach, where it aids in the mechanical digestion of food.
The third layer of smooth muscle is arranged obliquely, in addition to the other two layers which are oriented longitudinally and circularly. This unique arrangement allows the stomach to efficiently churn and mix the food bolus with gastric secretions, ultimately forming a partially digested substance called chyme. The churning and blending action ensures that the food is broken down into smaller particles, increasing the surface area for further enzymatic digestion.
As the chyme is mixed and propelled through the stomach, the coordinated contractions of the smooth muscle layers help to regulate the rate at which it enters the small intestine. This controlled movement ensures that the chyme is adequately processed and broken down, optimizing the absorption of nutrients in the small intestine.
In summary, the third layer of smooth muscle in the stomach plays a crucial role in promoting the continued propulsion and blending of the food bolus, ultimately contributing to effective digestion and nutrient absorption.
