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.
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
g The dominant food chain in a kelp forest ecosystem is made up of the three species below, listed with their trophic levels. If sharks enter a kelp forest ecosystem and begin feeding on sea otters, they would have a positive indirect effect on which species
Answer:
Crustaceans, sea urchins, mollusks and fish.
Explanation:
The positive effect occurs on crustaceans, sea urchins, mollusks and fish if the shark feeds on sea otter because sea otter feeds on crustaceans, sea urchins, mollusks and fish. Decrease occur in the population of sea otter due to introduction of shark in the ecosystem which indirectly increases the population of crustaceans, sea urchins, mollusks and fish. So we can say that a positive indirect effect occurs on crustaceans, sea urchins, mollusks and fish due to shark.
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.

Steps of Translation
Using the following word bank: anticodons, codons, mRNA, RNA; fill in the steps of translation.
The ribosome binds to a strand of _____
This nucleic acid has
three-nucleotide codes called ______
The three-letter codes are complementary
to ________
on ________
molecules. Each of these
molecules brings with it an amino acid, which will become part of the growing polypeptide.
Answer:
The correct answer is - mRNA, codons, anticodons, RNA.
Explanation:
During the translation process of protein synthesis, the mRNA strand is attached with the ribosome in order to translate the three-letter nucleotide sequence that is called codons or triplet code into specific amino acids.
These three-letter codes are complementary to the anticodons on the RNA (tRNA) molecules. These nucleic acid molecules with ribosomes bring with them an amino acid to make a polypeptide chain.

1. Place these events in the correct order to show
the cause-and-effect relationships that lead
to algae blooms.
a. decomposers that break down dead
algae take in oxygen for cellular
respiration
b. lack of oxygen causes fish and other
aquatic organisms to die
c. excess nutrients from fertilizer are
transported by rain to nearby bodies of
water
d. people overfertilize crops and lawns
e. algae overgrow, become overcrowded,
and die
f. excess nitrogen and phosphorus leads
to overgrowth of algae
The overgrowth of microscopic algae is an algal bloom. The correct order is people overfertilize, excess nutrients transported by rain to nearby water bodies, excess nitrogen and phosphorus leads to algal bloom, algae overgrow, become overcrowded, decomposers that break down dead algae take in oxygen for cellular respiration and finally lack of oxygen causes death of fish and other aquatic life.
What are algal bloom?The overgrowth of microscopic algae or algae-like bacteria in fresh or salt, waters is referred to as algal bloom.
Depending on the type that cause it, an algal bloom may produce bad-smelling, foam, or a paint-like slick.
According to the given scenario, the correct order will be:
People overfertilize crops and lawns.Excess nutrients from fertilizer are transported by rain to nearby water bodies.Excess nitrogen and phosphorus leads to overgrowth of algaeAlgae overgrow, become overcrowded, and die.Decomposers that break down dead algae take in oxygen for cellular respiration.Lack of oxygen causes fish and other aquatic organisms to die.Thus, this was the correct order of events to show the cause-and-effect relationships that leads to algal bloom.

a convergent boundary is a location where tectonic plates move toward each other. which feature of the ocean floor is caused by one tectonic plate moving under another at a convergent boundary
a. a flat plain
b. a trench
c. a mid-ocean ridge
d. a continental shelf
Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Explanation:
Answer: B. a trench

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.

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.

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.

A lipoprotein particle functions to ________. dissolve polar lipids for excretion transport nonpolar lipid to body cells metabolize lipids into new substances dissolve polar lipids in urine store lipids in the tissues
Answer:
The correct answer is ''transport nonpolar lipid to body cells''
Explanation:
Lipoproteins are macromolecules whose function is to package insoluble lipids in the aqueous medium of plasma and transport them from the intestine and liver to peripheral tissues. They transport all the lipids that circulate in the plasma: free and esterified cholesterol, triglycerides and phospholipids. Plasma lipoproteins constitute a polydisperse and heterogeneous system of particles of almost spherical morphology, which have a hydrophobic nucleus or core formed by nonpolar lipids, that is, esterified cholesterol and triglycerides, and by a hydrophilic surface layer containing unesterified cholesterol, phospholipids and specific proteins called apoproteins.
