3. A few years ago the population of male blue moon butterflies on the island of
Samoa declined. One hypothesis for the decline of the male butterflies is that a
parasite infected the cells of female butterflies. The parasite was passed to
offspring through the females' eggs and killed the male butterfly embryos. At
one point during the decline, nearly all the butterflies in the population were
females, but after five years the number of males in the population increased
significantly.

Succession is always caused by natural events.

Answers

False

An ecological succession is a gradual change in the biotic community of the ecosystem with respect to changes in the non living factors and time until the ecosystem attains stability. A succession can occur due to natural as well as non natural or man made events. In non natural or man made events includes forests fires, nuclear and bomb explosion. These events will result in destruction of the ecosystem and with time and availability of suitable environmental factors species will colonized in the destructed area. This will promote succession in the destructed area.

Answers

Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.

Explanation:

Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

What are unsaturated fatty acids?

Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.

 

Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

What will happen if the DNA is not replicated?

O Mitosis will likely not occur.

Cytokinesis will occur before
mitosis.

O Mitosis will decrease the size of the cell.

O The number of chromosomes will reduce by half during mitosis.

Answers

Answer:

The cells within living organisms have the ability to grow and reproduce through the production of new cells. In order to ensure that an exact copy of the DNA is assigned to the new cells, a process called mitosis takes place. When a new cell is needed, the DNA is copied and allocated equally to new cells; then the cell splits in half. While mitosis is a precise system for distributing DNA, it is very complex and includes many cell components that must work in concert. When any one of these intricate steps fails, the results can be adverse for the cell and the whole organism.

During mitosis, a cell divides into two identical cells referred to as daughter cells. In order for both cells to be fully functional and to be able to mature, they each need a complete set of DNA. To prevent the mutations and errors in the DNA, the process has to be extremely accurate. Usually the error rate for copying DNA is around 1-3 errors for every billion base pairs. To get this extremely exact method of copying, there are many checks that happen within the process. The DNA helix unwinds and the strands separate to allow the enzymes used in replication to do their work. If the DNA strand is found to be broken or damaged, the entire process stops until it is repaired.  

This process has to occur before mitosis because once mitosis starts, the cell is already preparing to divide. Soon after it begins, microtubules are forming in order to separate the newly replicated chromosomes. The DNA replication process not only has to be completed before this point, but the DNA has to be wound back up and the two copies of the same chromosome (now connected at a point in the chromosome) have to get in position so that they can be pulled apart, each destined for its new cell.

What process is being used by the cell to move the molecules

Answers

Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process.

The process that is being used by the cell to move the molecules is known as diffusion.

Diffusion is a method that has to do with the movement of substances within cells. It is also a method that's used for small molecules so that they'll be able to cross the cell membrane.

It should be noted that the exchange of gas in the lungs of human beings operates through diffusion. For diffusion to take place, gaseous substances will have to go through the cell membrane in order to be able to go into a cell or out of the cell.

Diffusion also takes place where there is a spread in particles. Diffusion is a movement from the region of a higher concentration to a low concentration.

In conclusion, the correct option is Diffusion.

Incomplete question. Attached is the image of the map below.

Explanation:

From the map, we could notice the contour lines around the Chimney Bluff areas are closely packed together. In other words, the spacing between the contour lines is narrower than those found in other locations.

This assertion is accurate because it is a standard practice in many maps to indicate the steepness of an area by having the contour lines in close proximity.
