A dispersion pattern that indicates that resources are abundant, evenly distributed with little interaction within individuals is:_______.
Answer:
Uniform dispersion pattern.
Explanation:
Uniform dispersion pattern is a type of dispersion pattern in which resources are present in abundant quantity as well as evenly distributed with little interaction within individuals. Due to abundant quantity of resources , the population of organisms increases that leads to more population of individuals in the ecosystem. Due to abundant amount of resources, there is less competition as well as interaction between individuals that are present at that time.

g Name and describe two possible pathogens that could be responsible. The spinal tap reveals the presence of Gram-negative cocci in the CSF. What would be the likely diagnosis
Answer:
Explanation:
The missing information describing the status of the sick sophomore student is attached in the image below.
The first question says we should name and describe the two possible pathogens responsible for such.
The two possible pathogens are:
Virus and Bacteria.
Recall that, the College student experienced a severe headache, nausea, vomiting, neck stiffness, and fever.
These highlighted symptoms are commonly caused by meningitis which is a bacterial infection.
Surgeons, surgical tools, and scrub nurses must all be sterile when doing surgery; If any infection arises provided all crucial measures were not taking into consideration, it would harm the patient and there will be a risk of meningitis as a result of this.
SImilarly, given that In the CSF, the presence of Gram-negative cocci is shown via a spinal tap; then the likely diagnosis would be that:
The patient has suffered from Neisseria meningitis.
This is because Gram-negative cocci are the most prevalent cause of infection in persons of this age group and In the Gram stain test, it has a dark red color.

g Cells called ________ influence development by controlling the fate of other cells in their local environment
Answer:
Neighboring Cells
Explanation:
Neighboring Cells are known to be the type of cells that influence development by controlling the fate of other cells in their local environment.
Typically Neighboring cells through the process often referred to as Induction simply influence the development of other cells nearby or in their local environment. This process of cell influence is either by direct cell-cell contact or through the release of practice chemical signals.
Hence, in this case, the correct answer is "Neighboring Cells."

Burrowing owls sometimes build their nests in holes that were dug by prairie dogs, coyotes, or badgers and have been since abandoned. They sometimes line the nests with cattle or horse dung. Why
Answer:
To avoid extreme temperature and keep away predators.
Explanation:
Burrowing owls sometimes line the nests with cattle or horse dung in order to avoid extreme temperature. The cattle dung protect the Burrowing owls from extreme temperature of the surrounding so they make nests close to these cattle dung. These dung has many insects which is a food of Burrowing owls and this cattle dung also keep predators away from Burrowing owls.
A biologist grows bacterial cultures to see if there is a relationship between time and growth rate. Here are the data. Which hypothesis test would you use to see if there a relationship between growth rates and time
Answer:
Direct relationship.
Explanation:
There is direct relationship between growth rates and time which means growth rate of organism increases with the passage of time. Direct relationship means if one increases the other automatically increases and if one decreases, the other also decreases. The growth of bacteria becomes double when more time passes and vice versa. After every 20 minutes, the population of bacteria becomes double.

A group of researchers wants to determine the most effective antibiotic for killing the disease causing bacteria E. coli. They select 5 different antibiotics and determine how many cells were killed at the end of the experiment. The dependent variable in this experiment would be
Answer:
Number of cells killed at the end of the experiment
Explanation:
In research, the dependent variable is one whose value is dependent on another variable - a variable that is supplied by the researcher during the course of the experiment which is also known as the independent variable.
In this case, since the main objective of the research was to determine the most effective antibiotic against the E. coli, the variable that is supplied by the researcher (the independent variable) is, therefore, the different antibiotics while the variable whose value varies based on which of the antibiotics is introduced is the number of dead bacterial cells.
Therefore, the dependent variable is the number of cells killed by each antibiotic.

What do you predict would happen if hydrogen bonds formed between any two nitrogenous bases in DNA ?
Answer:
I believe replication would not be possible, therefore the DNA would cease to help recreate cells which are essential to the human body.
Explanation:
This question by far is highly interesting, in fact it is very controversial too. However, with the sudden beginning of an actual hydrogen bond forming within nitrogenous bases, then replication would not be possible. This is so because replication relies only on nitrogenous bases rather than hydrogenous bonds. Therefore, resulting in a possible defect in the process of replicating to occur. However, if possible, I believe there might be even a chance of a mutation to occur, yet that is highly rare given the stance that the DNA molecule would not be able to pretty much do anything if that were to occur.
Which of the following species would have the greatest chance of going extinct?(1 point)
a species with a fast reproduction rate and lots of genetic variation living in a changing environment
a species with a fast reproduction rate and lots of genetic variation living in a stable environment
a species with a slow reproduction rate and very little genetic variation living in a changing environment
a species with a slow reproduction rate and very little genetic variation living in a stable environment
Extinction of the species refers to the death of the total species from the planet. The species with a slow reproduction rate and little hereditable variability habiting changing conditions will extinct first.
What factors influences the extinction rate?Many biological factors affect the survival of the organism as they play the most crucial role in the life and death of the species. The organism's reproduction rate, genetic modification and variability affect the survival of the organism.
The species that have a high rate of reproduction and high genetic variation can survive and continue their lineage when the surrounding habitat or the environment is altered or modified as they have better traits and characters.
The species in a changing environment with slow reproducing capability and very less genetic modification and variation will reduce the survival and adaptation chances of the organism and are more likely to go extinct first compared to the other organisms.
Therefore, option c, slow reproduction and less genetic variation in the species will go extinct first.

Evolution is an adjustment of the heritable attributes of natural populaces over progressive ages. These attributes are the outflows of qualities that are given from parent to posterity during generation. There are also three main types of evolution: divergent, convergent, and parallel evolution.
Explanation:
Are there telomeres on both the leading and lagging strand of DNA?
Answer:
To prevent the loss of genes as chromosome ends wear down, the tips of eukaryotic chromosomes have specialized DNA “caps” called telomeres. The overhang at the leading strand end of the chromosome is actually generated by enzymes that cut away part of the DNA 1start superscript, 1, end superscript
Maintaining high global biodiversity is important to provide ecosystem services to humans. Describe one cultural ecosystem service provided by diverse ecosystems.
Answer:
Ecosystem services of provision or supply
Explanation:
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials (such as salt), raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others. Provisioning service has an impact on the economy, as many of these products are used to commercialize.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provide a spiritual/religious space, are a source of inspiration. Ecosystems are considered to be cultural patrimony. Ecosystems are the source of scientific knowledge.
Support:Involves ecological processes needed for the production of the other three previously mentioned services. There are five different support services:
→ Soil formation
→ Photosynthesis
→ Primary production
→ Nutrients cycles
→ Water cycle
Under certain circumstances, regulation services can also be considered support services.
Support service affects human beings indirectly, or direct but causing an effect in a long-term period.
