Answer:
A possible factor for the above is best described by the inhibition model. This is a model of succession that allows for early colonizers to modify their environment making it only conducive for them hence ensuring their survival. If this is done successfully, by the second season, of the the 3 species of wild grass, only one will thrive in the field as a result of the phasing out of the other 2.
Explanation:
The inhibition model occurs as a result of the environment being modified by of the 3 species of wild grass by the 2nd season. This may have been as a result of it secreting biotoxins into the environment that destroys the other 2 wild grass, thus inhibiting their growth. This helps the organism thrive well during the 2nd season

Why does natural selection occur more when there is competition for resources?
Answers
Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.
In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.
Competition leads to differential survival and reproductive success among individuals.
Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.
These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.
Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.
Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.
Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

The high concentrations of persistent organic pollutants (POPs) in wildlife and humans living in the Arctic are not associated with which one of the following? Select one a. POPs are not easily broken down into harmless compounds b. POPs tend to bioaccumulate c. POPs have a high potential for long-range transport d. POPs are very soluble in water
Answers
The high concentrations of persistent organic pollutants (POPs) in wildlife and humans living in the Arctic are not associated with d. POPs are very soluble in water.
According to UNEP/GPA 2006a, a group of toxic chemicals known as POPs can persist in the environment for several years before breaking down. POPs are found all over the world, and the repeated evaporation and deposition of chemicals released in one region can deposit them far away from where they came from.
Mines, military installations, smelters, power plants, and a variety of other sources can produce and release POPs. However, the Arctic is only the source of a small number of pollutants. They are transported from farther south over long distances by air, water, and, to a lesser extent, migratory species. In contrast to warmer environments, the unique environmental conditions of the Arctic tend to "trap" pollutants because the cold encourages their persistence. Bioaccumulation is a method by which POPs are also stored and concentrated in the fatty tissues of animals. POPs are by and large profoundly lipophilic in this way not soluble in water. As a result, it is thought that POPs transfer to water at a relatively slow rate.

A spectrophotometer measures turbidity, but this measurement can be used to estimate cell number if you first generate a standard curve that relates CFU per ml culture (on the y-axis) to optical density (on the x-axis) across a range of cell concentrations for your culture. This method generally works well, but there can be some problems. If you were using this standard curve approach, which of the following would cause you to mis-estimate the number of CFU per ml in a culture from a measurement of optical density. a. the culture increases in density from one measurement to the next b. the culture produces a dark brown pigment under certain conditions c. the cells in the culture start clumping together d. the culture decreases in density from one measurement to the next e. the culture stops growing
Answers
In spectrophotometer measures ,the cells in the culture start clumping together and the culture produces a dark brown pigment under certain conditions.
The scientific assessment of a material's transmission or reflection characteristics as a function of wavelength is the focus of the discipline of electromagnetic spectroscopy known as spectroscopic analysis. Spectrophotometry makes use of spectrophotometers, photometers that can gauge the strength of a light beam at various wavelengths.
The spectrophotometer offers a "quick and dirty" technique to calculate the density of cells in a culture. Spectrophotometer measurements can be instantaneously translated into cell densities, unlike spot plates, which must be incubated for a number of days before colonies emerge. Nevertheless, the approach does not distinguish between living and dead cells. The spectrophotometric approach is based on the scattering of light by cultured cells. Light rays from a spectrophotometer may not reach the detector when they are deflected by a big particle, such a cell. Light scattering increases with sample cell density.

Which of the following areas would be the best location to store chemicals? • In a locked closet with ventilation • In the pool closet O Under the sink in the kitchen • On the ground in the garage
Answers
Answer:
A
Explanation:
I'm assuming you're talking about dry chemicals. An example of where dry chemicals should be stored is yeast, which should be treated in a similar method. In a locked closet, there wouldn't be a lot of external effects and with ventilation, the chemicals would maintain their structure. In a pool closet, obviously, there would be a lot of moisture, so this could cause some explosive reactions to some of the chemicals. The sink in the kitchen has the same properties as in a pool closet. Finally on the ground in the garage wouldn't be a good place to store chemicals as it is cold and has little to no ventilation.
Explain how diffusion restored homeostasis during the dialysis treatment.
Answers
During dialysis, diffusion facilitates the movement of waste products and excess fluids out of the blood, restoring homeostasis.
During dialysis treatment, diffusion plays a crucial role in restoring homeostasis. Homeostasis refers to the body's balanced state, where the levels of various substances are maintained within a narrow range. In the context of dialysis, diffusion refers to the movement of solutes across a semipermeable membrane.In hemodialysis, the patient's blood is circulated through a dialyzer, which contains a semipermeable membrane. On one side of the membrane, the patient's blood flows, while on the other side, a dialysate fluid flows. Due to a concentration gradient, solutes like urea, creatinine, and excess electrolytes in the blood diffuse across the membrane into the dialysate fluid.This diffusion process helps remove waste products and excess fluids from the blood, bringing it closer to the normal physiological range. By restoring the balance of solutes and maintaining proper fluid levels, diffusion in dialysis aids in restoring homeostasis and promoting the overall well-being of the patient.For more such questions on Dialysis:

Answers
This information, along with the discovery that rocks along the mid-Atlantic ridge were younger, was evidence for Seafloor spreading.
What is seafloor spreading?
Seafloor spreading is the hypothesis that the ocean's crust develops along the mid-ocean ridge system's undersea mountain zones and spreads out laterally away from them. The theory of plate tectonics, which revolutionised geologic thought throughout the final quarter of the 20th century, was developed in large part as a result of this concept.
When the seafloor spreads, tectonic plates, which are huge portions of the Earth's lithosphere, split apart from one another. Seafloor spreading and other tectonic activity processes are caused by mantle convection. Mantle convection is the term for the mantle's slow, turbulent circulation.
Hence the correct option is B; seafloor spreading.

Describe how the components of a meal containing fried fish and toast bread will be processed as they move through the digestive system of man
Answers
Answer:
Explanation:
When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:
1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.
2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.
3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.
4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.
5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.
6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.
Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

what is a coelom ? and why are some invertebrates described as acoelomates or pseudocoelomates
Answers
Answer:
The main difference between acoelomate and coelomate is that acoelomate is an invertebrate that doesn't have a coelom whereas coelomate is an invertebrate that has a true coelom.
A coelom is a fluid-filled body cavity, which is completely lined by the tissues derived from the mesoderm.
The coelom (or celom) is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs.
Unlike coelomates (eucoelomates), animals with a true body cavity, acoelomates lack a fluid-filled cavity between the body wall and digestive tract. Acoelomates have a triploblastic body plan, meaning that their tissues and organs develop from three primary embryonic cell (germ cell) layers.
Pseudocoelomate animals have a pseudocoelom (literally "false cavity"), which is a fluid filled body cavity. Tissue derived from mesoderm partly lines the fluid filled body cavity of these animals. Thus, although organs are held in place loosely, they are not as well organized as in a coelomate.

This means it can flow faster, which is necessary for supporting the metabolic rate of more complex animals such as vertebrates. Open circulatory systems are low-pressure systems that cannot meet the needs of a fast metabolism.
