During interphase, how does a cell prepare for division? Describe cell division, including the processes of mitosis and cytokinesis. Be sure to describe the mitotic steps.
Answer:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.

Cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will be inhibited from doing all of the following EXCEPT:________.
a) extend pseudopodia
b) move vesicles within a cell
c) contract muscle fibers
d) divide in two
Cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will be inhibited from doing all of the following except move vesicles within a cell. Hence option b is correct.
What is actin polymerization?Actin polymerization is defined as a monomers associate with and disassociate from the ends of actin filaments in this reversible process. Actin filament polymerization typically takes place over three phases: a steady state phase, an elongation phase, and a nucleation phase. Actin filament assembly involves the phases of nucleation, elongation, and steady state.
A cell-permeable fungus toxin called cytochalasin D attaches to the barbed end of actin filaments and prevents both subunit interaction and separation. About 20 known mold-derived substances collectively known as cytochalasins impact actin stress fibers and cause fast actin depolymerization.
Thus, cytochalasin D is a drug that prevents actin polymerization. A cell treated with cytochalasin D will be inhibited from doing all of the following except move vesicles within a cell. Hence option b is correct.

Modern domesticated pigs are descendants of the wild boar(Susscrofa). Through the domestication process, human have artificially selected for certain traits. Identify two of these traits, and briefly explain how they benefit modern society. Be sure to identify the trait, explain why it was artificially selected and how it benefits modern society.
Answer:
Meat for food and small size for pets
Explanation:
Artificial selection is the process by which humans control desirable phenotypic characteristics in plants and animals by applying selective breeding techniques to perpetuate these traits in the population. A example of artificial selection includes the process of domestication of modern pigs (Sus domesticus). It has been shown that the modern pigs derived from the wild boar (Sus scrofa), which were domesticated separately 9,000 years ago in China and Western Asia. For example, by artificial selection, humans have domesticated moderns pigs to use them as livestock for direct consumption (i.e., for their meat). Moreover, there are pig populations that have been artificially selected as pets (e.g., miniature Vietnamese Pot-Bellied pigs).

The Hawaiian Islands are located in the middle of the Pacific plate, but they contain volcanoes. What
accounts for the volcanoes on these islands even though they aren't found along a plate boundary?
Explanation:
This hot spot partly melts the region just below the overriding Pacific Plate, producing small, isolated blobs of magma. Less dense than the surrounding solid rock, the magma rises buoyantly through structurally weak zones and ultimately erupts as lava onto the ocean floor to form volcanoes.

Which energy source uses heat from underground?
O A. Nuclear
O B. Geothermal
O C. Solar
O D. Hydroelectric
Answer:
The answer is geothermal (b)
The correct answer is B. Geothermal.
This is true because geo relates to the earth and thermal relates to heat.
When you put those two words together, it means heat from the earth.
A is incorrect since the energy sources comes from the fission or splitting of atoms.
C is incorrect since solar energy relates to heat or energy from the sun.
D is incorrect since hydro means water and therefore hydroelectricity is an energy source that is made from water.
If genes from an organism, such as a bacterium, are inserted into a cell of another organism, such as corn, why does the gene still function? (2 points) The organism receiving the gene will modify it so it can work. The gene carries the necessary enzymes to allow it to be read in corn. The genetic code is read in the same way by all organisms. The bacterium is similar enough to the corn that the gene is able to function.
Answer:
Because it other dominates the other genes. It mutates but still carries the Domininant Recesive gene is intact to the organism.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? A. In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant. B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells. D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answer:
Option C
Explanation:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Elysia chlorotica which is a form of sea slug feeds on a specie of the genus Vaucheria (an algae) and then retains only the chroloplasts of these algae which it uses for its own supply of energy.
The algal partner in lichens is the photosynthesizing partner. It produces food and this is its role in the relationship. The fungi are heterotrophs and cannot photosynthesize food. The fungi contribute to the relationship my absorbing mineral and water and presents it to the algae.
Answer:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

If DNA replicated conservatively instead of semi conservatively, what would the banding pattern look like in a tube containing heavy nitrogen DNA (15N) grown in regular, or light, nitrogen (14N) for 1 generation? A. There would be one band of heavy DNA and one band of light DNA. B. There would be one band of intermediate DNA, and one band of light DNA. C. There would be one band of heavy DNA and one band on intermediate DNA. D. There would be one band of intermediate weight DNA.
Answer:
A. There would be one band of heavy DNA and one band of light DNA.
Explanation:
First, we must exclude that a 15N DNA is related to a heavy nitrogen, while a 14N DNA is related to a light nitrogen.
After that, it is important to understand what conservative DNA replication would be. This type of replication implies that the strands of the parental DNA would not be separated to form the daughter strands. Thus, the replication occurs with the DNA strands together, the daughter strands of newly formed DNA are also formed together, in this case. Thus, the parental 15N DNA would form another 15N DNA molecule, the same goes for the 14N molecule. With that we can say that the answer to your question would be "there would be a heavy DNA band and a light DNA band."

A person cannot produce several types of proteases. Name the problem this specific person probably has and explain why.
Answer:
The person have excess amount of proteases and when this happen, the person will protein breakdown in the body or lack of protein in the body which can affect most of the organs in the body.
Explanation:
Under normal conditions in the body, blood and body tissues have a specific potent enzyme called proteases. Protease help in the breakdown of protein in the body and play important roles in defending or fight against incoming infections and inflammatory processes in the body .There is need for thslese proteases to be regulated or control because overactivity can lead to protein destruction which will lead damage of different body organs. In order to control this, blood and other tissues in the body posses enzymes with protease inhibitory activity, these enzymes help to prevent its from undergoing excessive action and potentially harmful effects.
