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.
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.

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.
Which pie graph is shaded to best represent the approximate percentage of time that humans have existed during Earth’s entire history?

Explanation:
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.
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.

what is definition of biome
Answer:
a large naturally occurring community of flora and fauna occupying a major habitat, e.g. forest or tundra.
can someone help me with the ones that are blank i will give brainliest.
Answer:
Heritable - transmittable from parents of an organism to their offspring
Protein - genes provide the instructions to make these
Mutation - a slight change in an organism or population that is not normal
Gene - carried in the nucleus of a cell to determine what a cell makes
Resistance - the genetic ability of an organism to repel an attack to their survival
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.
The relationships among different orders of millipedes are shown in the cladogram. Based on this cladogram, which statement best describes relationships among millipede orders? Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta. Spirostreptida is more closely related to Glomerida than Sphaerotheriida is to Glomerida. Polyzoniida is more closely related to Glomeridesmida than Sphaerotheriida is to Glomeridesmida. Merocheta is more closely related to Glomeridesmida than Glomerida is to Glomeridesmida.
Answer: Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta
Explanation:
Your question isn't complete as you didn't attach the picture needed to solve the question but I searched online and got the picture which is attached below.
Therefore, based on this cladogram, the statement best describes relationships among millipede orders is that Stemmiulida is more closely related to Merocheta than Penicillata is to Merocheta.
Therefore, the correct option is A

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.

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.
A state of economic scarcity exists when consumers:
Answer:
Scarcity exists when there is not enough resources to satisfy human wants. One of the most widely known examples of resource scarcity impacting the United States is that of oil. As global oil prices increase, local gas prices inevitably rise.
