Sea otters are found primarily off the coast of California. They are one of the main predators of sea
urchins, Sea urchins feed on the roots of kelp beds, effectively killing large areas of kelp. Kelp beds
are important because they provide a safe location for several species of fish to spawn and hatch
their offspring. Data suggests that sea otters are a keystone species in their ecosystem.
What will most likely happen to this ecosystem if sea otters are permanently removed?
ОА.
OB.
Other species will evolve the ability to eat sea urchins, keeping the urchin population
under control.
The sea urchin population will rapidly increase, resulting in less kelp and a decrease
in biodiversity.
Sea urchins will assume the role of keystone species, allowing the ecosystem to remain
balanced,
OC.
Fish that reproduce in kelp beds will adapt to living in open water, becoming the primary
producers in the area.
Answer:B The sea urchin population will rapidly increase, resulting in less kelp and a decrease

Answer:
almost all of our food contain them .so answer is option C
Explanation:
Almost all of our foods contain food spoilage microorganisms.
What are food spoilage microorganisms?When there is an unpleasant change in the meal's usual state, food spoiling develops. This could be a modification to the way the meal looks, feels, tastes, or smells. The usual culprits for spoilage are bacteria, molds, or yeasts. The appearance of green fuzzy spots on a piece of bread is a classic sign of rotting.The most common bacteria linked to spoiling include Lactobacillus spp., Carnobacterium spp., Lactobacillus spp., and Brochothrix thermophacta. The primary spoilage organisms in cultured foods like yogurt, sour cream, and buttermilk are yeasts and molds. Butter can become spoiled by yeasts, molds, and Pseudomonas bacteria. Butter is more prone to surface mold growth than bacterial deterioration because of its high fat content and low water activity.learn more about food spoilage microorganisms here: https://brainly.com/question/17966536

Explanation:
what is the difference between mitosis and cytokenisis
Answer:
Mitosis refers to the division of a cell's nucleus into two. Cytokinesis refers to the further division of the cytoplasm of the cell, forming two daughter cells.
Explanation: I hope this helps :)
Explanation:
The Mitosis Phases
Mitosis itself is the division of the nuclei into daughter nuclei. It includes five phases of its own.
Prophase: Here, chromosomes become more condensed in the nucleus, and the nuclear membrane dissolves. The mitotic spindle forms from the centrioles, which have split and moved to opposite poles (sides) of the cell. This spindle is made of proteins in the form of microtubules.
Prometaphase: In this step, the chromosomes migrate toward the center of the cell. They are propelled by the mitotic spindle apparatus attached at the centromeres that joins sister chromatids. They begin to approach a line perpendicular to the direction they are moving, through their centromeres, called the metaphase plate.
Metaphase: In this step, chromatids align precisely along the metaphase plate via their centromeres, with one sister chromatid on each side of the metaphase plate.
Anaphase: In this step, the sister chromatids are pulled to opposite poles of the cell, releasing from each other at the centromere. The spindle fibers, again, are responsible for this motion.
Telophase: In this step, daughter nuclear membranes form around the newly formed daughter nuclei. At this point, chromatids are unpaired, as this generation's chromosome replication has yet to start. This is because cell division is not quite complete.
Cytokinesis
To define cytokinesis as a stand-alone phase, the difference between telophase and cytokinesis is best imagined by thinking of telophase ending the instant both daughter nuclear membranes are completely formed. Cytokinesis starts with a "pinching inward" from the top and the bottom of the cell, with one daughter nucleus on each side.
This "pinching" results from the formation of a protein structure called the contractile ring, which runs around the widest part of the cell under the membrane. When this shrinks inward, it pulls the membrane tighter along with it until the cell halves are completely separated by the now-finished "pinch."

Evaluate which of these components would be appropriate to include in the explanation to the patient and select ALL that apply.
A)The bacterial resistance includes all antibiotics.
B)The bacterial resistance to the antibiotic is genetic in origin.
C)The bacterial resistance to the antibiotic can be passed on to offspring.

Forensic entomology identifies the fauna on a dead body to make predictions about the death. C) ants, mites, and beetles frequent the body 3-17 days after death.
What is forensic entomology?Forensic entomology is the forensic branch that studies the cadaveric fauna associated with a dead body to make scientific conjectures.
Cadaveric fauna usually includes different forms of invertebrate species and their stages of development. There is a predictable sequence in which different species arrive at the dead body and inhabits it, and this sequence depends on the time the individual has been dead and the decomposition state of the body.
The species inhabiting the body and their developmental stage can be used as significant data to estimate the time of death, the region, and the circumstances under which the individual died.
Stages of decomposition depend on the region, but we can make this generalization,
1-3 days ⇒ adult flies and eggs, and a few larvae
3-5 days ⇒ bacteria and other microorganisms act. The decomposing body produces gasses that inflate the carcass. Larvae penetrate the body, release the gasses, and the carcass collapses.
5-15 days ⇒ Maggots, flies, ants, and beetles have already reached the dead body.
15-25 days ⇒ Most flesh is already consumed, and the body is in the advanced stage of decay. Although the number of invertebrates is low, the diversity of species is great. There are carpet beetles, ants, skipper flies, and mites.
25-50 days ⇒ Almost dry body with no flesh. Some arthropods are still feeding on it.
>50 days ⇒ Bones
Note: Remember that these are approximations and might vary according to the region and environmental conditions, such as temperature, precipitation, humidity, etcetera.
According to this information, we can say that ants, mites, and beetles frequent the body in warmer climates between 3 and 17 days. Option C.

Taking antibiotics for viral infections has no positive impact on individual health because
viruses are not killed by antibiotics. What negative impact does the unnecessary use of
antibiotics have on public health?
Answer:
Antibiotic Resistance
Explanation:
Antibiotic Resistance is when bacteria mutates or adapts to become resistant to antibiotics, wether by protecting the bacteria itself or limiting how the antibiotics can effect the body. This antibiotic Resistance can happen from using too many antibiotics, or using antibiotics but not having a high enough dose (so all the bacteria isn't killed). This can cause much more serious infections, like pneumonia and meningitis, to happen, and they can last longer, as they may not immediately respond to treatment. These can also spread to people who don't have a problem with antibiotic Resistance, but will get the antibiotic resistance bacteria which can mess with the other bacteria in their body, making them antibiotic resistant, which turns into a cycle of spreading bacteria and becoming resistant.

Answer:
Alec Jeffreys and the Pitchfork murder case: the origins of DNA profiling
British geneticist Alec Jeffreys began working in 1977 on a technique that could identify individuals through samples of their DNA. In 1984, he and colleagues devised a way to use a newly discovered property of DNA, isolated areas of great variability between individuals called restriction fragment length polymorphisms (RFLP), for forensic identification—the original DNA fingerprint.
In 1986, police asked Jeffreys for help in finding a man who had raped and killed two girls. DNA tests exonerated the primary suspect. Through a genetic dragnet, police found the perpetrator, Colin Pitchfork, who gave himself away when he asked a friend for a substitute blood sample.
Within a year, genetic fingerprinting was making the unique molecular structures of victims and suspects visible in criminal investigations around the world. Today, RFLP-based DNA analysis is being supplanted by newer techniques of genetic identification.
