Which of the following correctly describes the arrangement of the phospholipids in the lipid bilayer of the cell membrane? *
Phospholipids line up head to head, so the phosphate heads are separated from water.
Phospholipids line up head to tail, because opposites attract.
Phospholipids line up tail to tail, so the fatty acid tails are separated from water.
Phospholipids line up with no pattern, because they're molecules which move randomly.
Answer:
Two layers of phospholipids where the outer layer has the hydrophilic heads facing toward the outside of the cell and the inner layer have the hydrophobic tails facing toward the inside of the cell.

The chromosomes are located at the equator of the cell
Answer:
called the equatorial plane
Explanation:
During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane. There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.

1. Describe the course of the water cycle which formed in Biosphere 2
2. Deduce what would happen if you were to store your “Biosphere X” in the dark for a few weeks.
1) Solution
The sun warms the ocean surface and other surface water, causing liquid water to evaporate and ice to sublime. It turn directly from a solid to a gas. These sun driven processes move water into the atmosphere in the form of water vapor.
2) Solution
If we store the “Biosphere 2” in the dark for a few weeks, the water vapour will condense to form water.
About 3 million years ago, the Isthmus of Panama (a narrow strip of land connecting North and South America) formed, dividing marine organisms into Pacific and Caribbean populations. Researchers have examined species of snapping shrimp on both sides of the isthmus. Based on the morphological species concept, there appeared to be seven pairs of species, with one species of each pair in the Pacific and the other in the Caribbean. The different species pairs live at somewhat different depths in the ocean. Using mitochondrial DNA sequences, the researchers estimated phylogenies and found that each of these species pairs, separated by the isthmus were indeed each other's closest relatives. The researchers investigated mating in the lab and found that many species pairs were not very interested in courting with each other, and any that did mate almost never produced fertile offspring. Which process led to the formation of the species pairs of Pacific and Caribbean snapping shrimp
Answer:
Allopatric speciation
Explanation:
Allopatric speciation refers to the geographic separation of a continuous genetic background, originating two or more new geographically isolated groups. These divergences of the original population might be related to migration in different directions, extinction of geographically intermediate populations, or geological events. During these events of speciation, emerging new barriers impede genetic flow between groups, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
Different stages are involved in the allopatric speciation process:
• The emergence of the barrier.
• Interruption in the genetic flow
• Slow and gradual differentiation due to the occurrence of mutations in each population and their accumulation in time.
• Genetic divergence by natural selection and reproductive isolation, impeding the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection a secondary contact between the new species occurs.
The Panama isthmus is an example of allopatric speciation caused by an extrinsic geological barrier that interrupted the genetic flow between species driving to genetic changes and reproductive isolation.
Two different groups that evolved in allopatry might meet again in secondary contact if the barrier that separated them, disappears. In the Panama isthmus example, the groups that did mate, could not produce any fertile progeny because of postzygotic reproductive isolation. And the groups that did not mate, were not attracted to each other because of prezygotic reproductive isolation.
If you have a stressful job or an unhealthy diet, what impact might that have on your cells? Only 1 correct answer.
A. the DNA will all mutate and die
B. different genes may be expressed
C. no changes would occur to your DNA over your lifetime
Answer:
B. different genes may be expressed
Explanation:
If you're chronically stressed and your body is constantly flooded with cortisol, you will get sick easier because your white blood cell count will drop, your likelihood of developing tumors will increase and you'll also become more vulnerable to infection and tissue damage.
Answer:
B. different genes may be expressed
Explanation:
If we have a stressful job or an unhealthy diet, different genes may be expressed on our cells.
Malaria is a disease that kills over 800 000 people each year. What causes malaria and how is it spread? What drugs are used to treat this disease and why should Canadians be concerned about the spread of malaria worldwide?
Answer: Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person.

What is it called when genetic information is exchanged between homologous chromosomes during prophase 1?
A. Meiosis
B. DNA Replication
C. Crossing Over
Answer:
C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.
Answer:
C. Crossing Over
Explanation:
The crossing over is called when genetic information is exchanged between homologous chromosomes during prophase 1.
A scientist studied a population of birds for 10 years. During that time, the population was never fewer than 30 birds and never more than 50. Her data showed that over half of the birds born did not survive to reproduce, because of competition for food and predation. She noticed that In a single generation, about 90% of the birds that were born lived to reproduce, and the population increased to 90. Which inference(s) about this population might be true
Answer:
A particular population limiting factor or factors must have been removed
Explanation:
The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.
For the population to shoot up to 90 all of a sudden, it may be that one or more of the population limiting factors has been removed from the population. It could be that a major predator has been removed from the community or the competition for food/space is now significantly reduced due to more food/space in the community.
What are genes?
A. A whole DNA molecule that codes for many proteins
B. Section of DNA that code for a DNA molecule
C. Sections of DNA that code for a protein
Answer:
A. A whole DNA molecule that codes for many proteins
Explanation:
To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene.
Why do negative essay results not always mean the molecule is absent
Answer:
The concentration of the molecule may be too low to be detected
Explanation:
Negative essay results do not always mean the molecule is absent because the amount or percentage of the molecule to be detected could be too less to detect.
What are the negative assay results?
False-negative blocks haven't received as much attention as false positives, but they can lead to misdiagnosis and improper treatment candidate selection. Based on the failure of local anesthetic infiltration to relieve the pain from facet joint capsular distention, research on 15 volunteers who had MBBs with local anesthetic or saline and capsular distention estimated the rate of false-negative blocks to be 11%.
It was determined that "aberrant innervation" was a likely explanation for some instances of unsuccessful RF denervation in IA block responders. Vascular uptake is regarded to be one of the main sources of false-negative blocks. According to reports, this can vary from 6% to 30% per level. rates of 3.9% at cervical levels, 3.5% at lumbar levels, and 0.7% at thoracic levels, according to one research.
According to one study, even if the needle is relocated when vascular uptake happens, analgesia will only be experienced 50% of the time. Digital subtraction angiography has been demonstrated to increase the detection rate and is the most reliable method of identifying vascular uptake. Failure to distinguish between procedure-related discomfort and baseline pain, as well as missing a target nerve or nerves, are other potential reasons for false-negative blocks.
Therefore, a false negative result could be the result of low concentration.

what happens directly after metaphase
Answer:The third phase of mitosis, following metaphase and preceding telophase, is anaphase. Since the sister chromatids began attaching to centrosomes on opposite ends of the cell in metaphase, they're prepped and ready to start separating and forming genetically-identical daughter chromosomes during anaphase.
Explanation:
Answer:
The next phase is anaphase. The chromatids separate at the centromere. The spindle fibers begin to pull them to opposite sides of the cell.
