a volcano explodes and kills all but ten members of a population of primates. these ten continue to reproduce, but the allele frequency is now different from that of the original population. this is an example of , which is due to sampling error.
Some volcanic eruptions are explosive and others are not. The explosivity of an eruption depends at the composition of the magma.
If magma is thin and runny, gases can break out easily from it. whilst this type of magma erupts, it flows out of the volcano.
A very good example is the eruptions at Hawaii’s volcanoes. Lava flows hardly ever kill people because they pass slowly enough for people to get out of their way.
If magma is thick and sticky, gases can't escape easily. pressure builds up till the gases get away volcanoes and eruptions. an excellent instance is the eruption of Washington’s Mount St. Helens. on this form of eruption, the magma blasts into the air and breaks apart into portions referred to as eruptions
Tephra can range in length from tiny debris of ash to residence-length boulders.

In which two ways do plant cells use the sugar made in photosynthesis ?
• to produce phosphate groups
• to store inorganic matter
• to supply the plant with energy for life
• to make other types of organic molecules
The two ways in which plant cells use the sugar made in photosynthesis are to supply the plant with energy for life and to make other types of organic molecules. The correct options are c and d.
What is photosynthesis?Photosynthesis is a method that plants and other lifeforms use to transform light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Plants use their leaves to trap light energy during photosynthesis. Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar.
Plants use glucose for energy and to make other substances such as cellulose and starch. Cellulose is used to construct cell walls.
Thus, c and d are the correct options.

vernalization you are studying a winter-annual arabidopsis plants. you identify a strain with a mutation in the flc gene that renders it inactive. when do you expect this plant to flower?
The plant will never be able to flower.
What are annual Arabidopsis plants?
A plant is said to be annual if it completes all stages of its life cycle, from germination to the production of seeds, during a single growing season and then perishes when that season is over.
During the process of flower growth, from the vegetative to the reproductive phase, a number of genes, including SOC1, LFY, FLC, and others, play highly important roles. Which FLC gene is the repressor gene of SOC1 that result in the flowering of the plant, but after the cold treatment an additional gene called COLDAIR RNA in the process of vernalization represses FLC and causes flowering to occur. However, if COLDAIR RNA is unstable, it would be nonfunctional and the plant would never be able to flower because of this.
Hence, the plant will never be able to flower.

2. Which describes the alveoli?
O They have very thick walls to contain the air that enters the lungs.
They work with the villi to exchange oxygen and carbon dioxide.
They provide a large amount of surface area for gas exchange.
They are structures responsible for the production of our voice.
Alveoli work with the villi to exchange oxygen and carbon dioxide .
Alveoli are the smallest structure in the respiratory system. They are organized in bunches all through the lungs at the finishes of the parts of your respiratory tree, which is the tree-like design of paths that carries air into the lungs.
The walls of the alveoli are extremely slender. This lets oxygen and CO2 pass effectively between the alveoli and vessels, which are tiny veins.
Oxygen can pass from the alveoli to the vessels on the grounds that the centralization of oxygen is lower in the vessels than in alveoli. Essentially, CO2 moves the alternate way in light of the fact that the centralization of carbon dioxide is lower in the alveoli than in the vessels.

The chemical equation for the reaction when a water molecule is added to an atp molecule to break down atp into adp and a phosphate group is H2O + ATP -> ADP + Pi
Adenosine triphosphate (ATP) is a molecule that can store chemical energy in high-energy phosphoanhydride bonds. These bonds can be split to release chemical energy, for example in muscles. This process is known as ATP hydrolysis. The end result is an inorganic phosphate and adenosine diphosphate (ADP) (Pi). Another inorganic phosphate, energy, and adenosine monophosphate (AMP) can all be produced from ADP by additional hydrolysis (Pi).

Taxol is an anticancer drug extracted from the pacific yew tree that binds to microtubules and prevents their depolymerization. Which phase of mitosis or cell division would be inhibited by treatment with taxol?.
The phase of mitosis that would be inhibited by treatment with Taxol is: metaphase.
Mitosis is the process of cell division that divides the cell into two daughter cells without affecting the genetic composition of the cells. Hence it is an equational division where the ploidy of the cells is not affected. Mitosis is accomplished in following four phases: prophase, metaphase, anaphase and telophase.
Metaphase is the second phase of mitosis where the chromosomes align at the center or the equator of the cell. This is also called the metaphasic plate. The chromosomes are also attached to the spindle fibers, which then pull them apart in the next phase which is anaphase.

Embryos show a reduction and loss of body axis structures when Xenopus laevis eggs are exposed to 1.0 degrees C for 4 minutes or 8000 psi for 5 minutes during a crucial phase before initial cleavage. The deficits develop in a dose-dependent craniocaudal progression.
In the extreme, radial symmetric, completely axis-deficient embryos are produced. The time between pronuclear contact and mitosis, which is roughly when the gray crescent forms, is when the maximum sensitivity to cold and pressure occurs. This time spans from around 0.4 to 0.8. These findings are interpreted as follows: The Xenopus laevis egg contents are reorganized during the 0.4–0.8 phase in a way that is crucial for the development of the embryonic body axis later on.
Cytoskeletal components are involved in the reorganization process; some of these components are D2O-protected and susceptible to UV, pressure, and cold. It is possible to understand rescue by oblique orientation as the outcome of a gravity-driven rearrangement of the egg's contents, replacing the impaired normal mechanochemical reaction in treated Xenopus laevis eggs.

Which term describes the rearranging of genetic material between nonhomologous chromosomes without a net loss or gain of genetic material?.
Translocation is the term that describes the rearrangement of genetic material between non-homologous chromosomes without a net loss or gain of genetic material.
Chromosome translocation is an abnormality of the chromosome that results from the rearranging of pieces on non-homologous chromosomes. When chromosomes break during meiosis and the resultant fragment is linked to another chromosome, translocations take place. It does not undergo any net loss or gain of genetic material during the process.
The exchanged sections are referred to as "translocated segments," and the reorganized chromosome is referred to as a "derivative." The translocation is balanced (i.e., neither gains nor losses of genetic material occur) and typically leads to normal development as long as there is no genetic material loss. Rarely, the breaks disconnect a gene from its regulatory element or occur within a gene, which may subsequently result in a phenotype.

When cells are not given glucose and oxygen, necrosis, or cell death, takes place. The fact that cells can endure hypoxia is noteworthy. The intrinsic apoptotic pathway is activated by acute oxygen deprivation, and this results in a lowering of the mitochondrial membrane's potential, according to early study.
How is cellular respiration impacted by a lack of oxygen?When oxygenated blood is not given to cells, cellular membranes break down, causing anaerobic metabolism and a loss of adenosine triphosphate (ATP).
Since oxygen is needed for algae to break down, fish and other aquatic species have much less DO available to them, which has an adverse effect on their health and frequently results in fish death. Low DO in water is also brought on by the decomposition of aquatic plants and phytoplankton that are submerged.
