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.
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.
Explain to me what a animal classification is
Classification is a method of grouping things together based on common qualities. Animal classification is critical since it aids in the identification and naming of all species on the planet. Animalia, Chordata, Mammalia, Primata, Hominidae sapiens are the classifications for humans.
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.
You are trying to program E. coli bacteria to generate N-acylethanolamide, lipids that have been found to help suppress appetite. In order to do this, you need to transfer the gene for the enzyme N-acyltransferase from the plant Arabidopsis Thaliana into the E.coli bacteria.
The transgene, which codes for ***********, will also need to have a**********
for RNA polymerase and a ********** that would fluoresce to let you know the insertion was successful. You would also need a********** , a small circular piece of bacterial DNA.
Then you would hunt for a *********** that would cut the plasmid once and also cut the transgene out from its host.
FILL IN THE **********
Answer:
The transgene, which codes for N-acylethanolamide, will also need to have a transcription initiation site for RNA polymerase and a selectable marker (reporter gene) that would fluoresce to let you know the insertion was successful. You would also need a plasmid, a small circular piece of bacterial DNA. Then you would hunt for restriction enzymes that would cut the plasmid once and also cut the transgene out from its host.
Explanation:
A transgene can be defiend as a gene (in this case, the N-acylethanolamide gene) which has been transferred by using genetic engineering techniques from one organism to another. The RNA polymerase is an enzyme required to copy a DNA sequence (e.g., a gene) into an RNA sequence, during transcription. RNA polymerases bind to specific DNA sequences called transcription initiation sites on the DNA template, and this binding triggers the initiation of the transcription. A plasmid is a small circular DNA molecule separated from chromosomal DNA which is capable of replicating independently of the chromosomal DNA. Plasmids are widely used in genetic engineering to clone/transfer/manipulate transgenes. During transgenesis, the plasmid is cut with a specific restriction enzyme in order to ligate the transgene of interest into the plasmid. Finally, the green fluorescent protein (GFP) gene is a selectable marker (i.e., a reporter gene) that indicates which cells were successfully modified because its expression can be detected without any substrates.
Many fruits can be preserved by candying. The fruit is immersed in a highly concentrated sugar solution, and then the sugar is allowed to crystallize. How does the sugar preserve the fruit
Answer:
By removal of water.
Explanation:
Sugar preserve the fruit by replacing some of the water in the fruit. This natural process preserves the fruit's original color, texture and shape by preventing remaining water of the fruit from leaving its cellular structures. Due to removal of water with the help of sugar from the fruit helps in preserving the fruits for long time period. The sugar helps in drying of the fruits so that's why we can say that sugar preserve the fruits.

What is a Menstrual Cycle??
Answer:
The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that make pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the uterus to receive a fertilized egg. These cycles are concurrent and coordinated, normally last between 21 and 35 days in adult women, with a median length of 28 days, and continue for about 30–45 years.

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.

Which of the following criteria have to be met for a species to qualify as invasive? Endemic to the area, spreads rapidly, and displaces foreign species Introduced to a new area, spreads rapidly, and displaces other invasive species Introduced to a new area, spreads rapidly, and displaces native species Endemic to the area, spreads slowly, and displaces native species
Answer:
Introduced to a new area, spreads rapidly, and displaces native species.
Explanation:
A species is invasive when they were not present in the area before, and once that they are there, they reproduce at a high peace. The fast reproduction rate, which leads to the spread of the species in the area, causes a disbalance in the ecosystem since it eats other species, which are native because they are from that area or other species' food. As a consequence, native species die or are reduced in number because the new species invaded their habitat.
An invasive species is not endemic because they are not native to that particular area. They are always external to this one.

Usually scientists looking for life on other planets try to determine first if the planet had or has evidence of water. Develop a rationale for this
based on cellular chemistry
Answer:
water is essential for life as we know
Explanation:
Water (H2O) is essential for life (i.e. carbon-based life) because this molecule has unique chemical properties. First, water is a universal solvent that helps cells to transport and use essential molecules (e.g., oxygen and nutrients). Second, water molecules help cells to maintain their shape/structure by generating pressure within the cells. Third, the polarity of water helps the formation of phospholipidic membranes because phospholipids have polar heads that interact with water and nonpolar tails that interact with each other. Fourth, water has a high heat capacity, thereby helping to regulate the temperature in the (intracellular) environment. Finally, water molecules also have unique adhesion and cohesion properties that enable the movement of substances against gravity (adhesion) and create a surface tension (cohesion) that helps to the formation of bubbles with water.

How are seamounts able to support diversity?
Answer:
A seamount is a large geologic landform that rises from the ocean floor but that does not reach to the water's surface
Explanation:
It is able to support diversity because many deep-sea animals, such as corals and sponges spend most of their lives permanently attached to rocks. As opposed to a flat seafloor, seamounts rise off the ocean bottom and interact with water flowing around them. These water currents can wash off sediment on a seamount, exposing rocks that are ideal habitat for animals that require hard substrate to grow and attach.
Also, because these animals cannot move around to find food, they are dependent on ocean currents to bring their food to them. The strong currents running over a seamount can deliver animals living along its flanks with a constant supply of planktonic food. Nutrients like nitrates and phosphates, which are critical to the growth of phytoplankton, are lifted from the deep to the sunlit surface waters. These nutrients fuel an explosion of planktonic plant and animal growth and attract larger animals such as whales, sharks, tunas, and seabirds to a veritable feast.
