Answers

Answer 1

The thick layer of material that separates the oocyte from the inner layer of granular cells, contains glycoproteins, and plays a role in the binding of a sperm cell to the surface of an egg after ovulation is called the zona pellucida.

The zona pellucida is a glycoprotein layer that surrounds the oocyte and provides a barrier between the oocyte and surrounding cells. It helps to prevent polyspermy by allowing only one sperm to penetrate and fertilize the oocyte.

The binding of the sperm to the zona pellucida initiates a series of reactions that lead to the fusion of the sperm and egg membranes, resulting in fertilization.

glucose is stored in muscles and the liver in the form of group of answer choices glycogen. triglycerides. nitrogen. glucagon.

Answers

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.

which microorganisms would be expected to contribute co2 to the atmosphere? there is more than one correct choice, select all that apply to receive credit.

Answers

Microorganisms that contribute CO₂ to the atmosphere include bacteria, fungi, and algae. These organisms play a vital role in the carbon cycle, facilitating the release of carbon dioxide into the atmosphere through processes such as respiration, decomposition, and fermentation.

Bacteria, such as decomposers, break down organic matter and release carbon dioxide as a byproduct of their metabolic activities. This process is essential in recycling nutrients and maintaining a balanced ecosystem. Some bacteria, like methanotrophs, consume methane and produce carbon dioxide, thus regulating greenhouse gas levels in the environment.

Fungi also contribute to CO₂ production through decomposition. As saprophytic organisms, they break down dead plant material, releasing carbon dioxide and nutrients back into the atmosphere and soil. Moreover, fungi are involved in symbiotic relationships with plants, where they assist in nutrient absorption and produce carbon dioxide during respiration.

Algae, specifically phytoplankton, are essential contributors to CO₂ production in aquatic environments. They undergo photosynthesis, converting sunlight into energy and releasing oxygen. However, they also respire, consuming oxygen and producing carbon dioxide as a byproduct. Algal blooms, which result from an overgrowth of algae, can lead to significant CO₂ production and impact the surrounding environment.

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

Answers

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.

The presence of a third layer of smooth muscle assists the continued _______ and blending of the ______

Answers

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.

The process by which natural selection produces a divergence in traits and resource use among sympatric species is called __________________ displacement

Answers

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.

during which phase of karyokinesis (mitosis) do duplicated chromosomes separate? group of answer choices anaphase metaphase

Answers

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.
