an island has a population of 100,000 moths that has 98% gray individuals and 2% black individuals. generation after generation, this ratio and population size remains basically the same. after a hurricane, 15,000 black moths are blown onto the island. after 2 years, a. the percentage of gray moths will increase. b. all of the black moths will be killed off. c. the black moths will emigrate back to their original habitat. d. the percentage of black moths will increase. e. all the white moths will be killed off.

Answers

Answer 1

When 15,000 black moths are blown onto the island the percentage of black moths will increase because high gene flow increases the size of the population and of the geographical area in which genetic material occurs.

What is gene flow?

It is also called gene migration. It is the transfer of genetic material from one population to another and takes place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring. It is important to counteract the evolutionary forces.

Factors affecting gene flow:

Natural selectionMutationGenetic driftmigration

Allele frequency or gene frequency is the relative frequency of an allele at a particular locus in a population.

After a hurricane, the addition of 15000 moths onto the island is an example of gene flow.

Here, after the hurricane, 15000 black moths are blown onto the island so the percentage of black moths increased from 2% to a higher rate. in this way gene flow occurs and the population of black moths increases.

Hence, Gene flow is the reason for the increase in the population of black moths.

A city is a good analogy for a cell because it includes all components to function in a system. Organelles may be analogous to people since they play specific roles.

Why a city is a good analogy for a cell?

A city is a good analogy for a cell because both systems need to maintain homeostasis. This state of internal equilibrium is achieved by the normal function of all components. In a cell, the component includes organelles, while a city is composed of people.

The cell is an open system in the same way that a city. All the cities are interconnected through globalization in a similar manner to the cell in a body to form tissues and organs.

which is not a correct association? group of answer choices s stage-dna synthesis m stage-mitosis and cytokinesis interphase-shortest stage of the cell cycle g2 stage-metabolic preparation for mitosis

Answers

Anaphase is the stage where DNA is synthesized, m is the stage during which mitosis and cytokinesis occur, and g2 is the stage during which the metabolism is set up for mitosis.

Which mitotic phase lasts the shortest?

The sister chromatids separate and the chromosomes start to move to the opposing ends of the cell during anaphase, the shortest stage of mitosis. By the end of anaphase, the cell's two halves have an equal number of chromosomes. Daughter nuclei arise in two during telophase.

What sequence are the four interphase stages in?

G1 phase (cell growth) is followed by S phase (DNA synthesis), which is then followed by G2 phase during interphase (cell growth). Interphase is followed by the mitotic phase, which entails mitosis and cytokinesis and results in the formation of two daughter cells.

In the phenomenon of wilted lettuce leaves became fresh after soaking in cold water is also known as osmosis.

How is osmosis process?Re-freshing lettuce through cold water, called by osmosis process. this phenomenon happen because lettuce has a more concentrated medium and has a higher hypoosmotic pressure, so that water is absorbed into the lettuce.In a more general explanation, lettuce itself consist of >80% water content, besides that lettuce is a leaf-shaped plant and has high evaporation of water through natural openings, the width of the leaves owned by this lettuce affects the rapid rate of evaporation of water and the wilting process. The natural opening mechanism that occurs is also influenced by temperature, air, and humidity. At increased temperatures, the openings that occur will be larger so that the decay process takes place more quickly and vice versa. Therefore lettuce becomes fresh when soaked in cold water.However, this method cannot be implemented on all vegetables, especially on vegetables that do not go through the wilting process before rotting.

Since nutrients are absorbed through the surface of the cell membrane, and nutrients are needed by the entire volume of the cell, a smaller Surface Area / Volume ratio would mean the cell has a better ability to "feed" itself.

The cell needs to take in nutrients like carbohydrates and amino acids, and it also needs to release certain metabolic waste products. Such molecules are either pushed throughout the membranes by membrane transporters as well as diffuse passively along protein channels in assisted diffusion.

What is called a virus in a computer is an annoying file, so every file that can interfere with the performance of the OS is a virus, this annoying file can be in the form of ordinary files that we intentionally store but are damaged, Worms, Trojan Horses, Spyware, and malicious malware that is installed either intentionally  or not.  Actually we don't need to be afraid of being too much with what is called a virus in a PC / laptop, as long as we want to take the anticipatory steps correctly, then the possibility of a virus can interfere with our laptop is very small.

Here's how to prevent and avoid viruses from entering your computer or laptop:

1.Use a compatible and bona fide antivirus, always update the antivirus;

2. If your computer or laptop is often used to browse the internet, then use an antivirus that has Internet Security features;

3.Activate Firewall on Windows that you are using;

4.Always update Security Update on Windows Security;

5. Do not get into the habit of storing data on drive C for too long;

6. Identify all the data that you store on the laptop, and immediately discard/delete if there is data that you do not recognize;

7. Delete registry files that are not needed regularly;

8. If you are going to transfer data from another device/device, try not to open it when it is still connected, so send/copy it directly and then disconnect the device/device;

notice that there are differing numbers of lobes on the right and left lungs. why would this be the case?

Answers

There are differing numbers of lobes on the right and left lungs because the left and right lungs are different in size and shape to make room for other organs that intrude on the thoracic region.

What do you mean by lobes in lungs?

Each lung has lobes that are partitioned off from one another by tissue fissures. The left lung, which is slightly smaller due to the heart's asymmetrical position, has two major lobes compared to the right lung's three. Each lobe is further divided internally into hundreds of lobules.

What is the function of lobes in lungs?

The left lung has two lobes while the right lung has three, each of which resembles a balloon packed with sponge-like tissue. Although each lobe of the bronchial tree receives air from a different branch, they all perform the same task: supplying the bloodstream with oxygen and expelling carbon dioxide.

Directing and maintaining the internal cytoskeleton and elements of the extracellular matrix are two of the primary functions of peripheral proteins. Organelles, filaments, and tubules work together to create both of these structures.
