Answer:
The correct answer is - Because of hunting, organisms such as bears and wolves are fewer in number.
Explanation:
Evolution is the change in the characteristics or traits of the species that are developed over several generations by the process called natural selection. Natural selection is the process of transferring the genes or traits that help in the survival of organisms.
Among the given statements all the are the example of the evolution that is resulted from human activity except the extinction or fewer the bears and wolves due to hunting. Other examples are showing evolution as they developed characteristics over generations.

What conditions on the Moon's surface do
you think engineers had to consider when they
designed the lunar rover?
Help pls. Explain
Answer:
The differences in gravity, craters on the moon and unknown materials.
Explanation:
These would all be helpful to consider.
The rover would have to be light enough to launch with the Apollo payload as it was, but also be sturdy enough to traverse all types of terrains, conquer slopes up to 25 degrees, and function in temperatures ranging from -279 to 243 degrees Fahrenheit
Note that air suspension, which is in most cars, wont work, since theres no air. They need to automate a way to land the rover without breaking it to also. It also needs to survive long enough.

What could happen if the wrong organism is identified as the cause of disease?
If the wrong organism is identified, then people would probably be in danger. Because you wouldn't know if the actual species is deadly or not. Lets say that the wrongly identified organism isn't deadly, but the real one is. Everyone is just strolling along, and then you're dead because it bit you.
And of course, if you're coming up with a cure, (because both are toxic) you're making the wrong one. Which could harm people just based off their bodies and what you're putting into them. Everyone is different.

How does interphase prepare cells for mitosis?
Answer:
The largest part of the cell cycle is the interphase. Some 80-90% of the life of a cell is spent inter phasically. This is the time for a cell to grow and prepare for cell breakdown.
Explanation:
The cell prepares for cell division, also for interphase (which includes mitosis and cytokinesis). The cell grows larger until its starting point has doubled in size. The first stage, called the G1 phase, takes place.
The S phase is the next phase of the interface. The cell's DNA is copied this time. There are two DNA sets so that each daughter cell can receive one copy.
The final part of the intersection is the G2 phase. The cell is about to grow. All organelles like the endoplasmic reticulum and Golgi device will be doubled.
The interface is when the cell grows and produces sufficient matter to be divided into two cells. Before mitosis can start, the interphase must be completed.

What is the least diverse species in PA
Hi. Your question is incomplete and it would be necessary for a text, a table, a graph or any other element that demonstrates the diversity of species to be presented for this question to be answered. However, I will try to help you as best I can.
The word "diversity" refers to differences and varieties that the same element presents. In this case, a species with little diversity is a species that shows little or no difference between its members. So, to answer your question, you need to identify the species that has the least difference within the community it makes up. For this, you will need to analyze your question complete, with all the elements that make it up.
Which statement describes a difference between the nitrogen and carbon cycles?
The nitrogen cycle occurs entirely in the ocean.
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
The carbon cycle requires freezing temperatures.
The carbon cycle involves only plants.
Answer:
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria
The primary distinction between the carbon and nitrogen cycles is that the former involves recycling carbon, whilst the latter involves recycling nitrogen. There are numerous ways for both systems to recycle carbon and nitrogen. With gases, both cycles begin and end. Thus, option B is correct.
What between the nitrogen and carbon cycles?Both go through chemical changes that change the shape of the molecules they are contained in. All organisms that are living contain both nitrogen and carbon. Both entail releasing the element into the atmosphere in a molecular form. The cycles start and end as gases.
Therefore, The amount of nitrogen that can be absorbed into organic matter and then recycled rises as the flux of carbon does.Both involve releasing the element as a molecule form into the atmosphere. As gases, the cycles begin and finish.

If a virus can't attach to a cell it can't inject its genetic material.
A. True
B. False
Answer:
I beleive its true
Explanation:
Answer:
True...
Explanation:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host (and the cells within the host) that can be infected by a particular virus. This can be illustrated by thinking of several keys and several locks where each key will fit only one specific lock.
The nucleic acid of bacteriophages enters the host cell naked, leaving the capsid outside the cell. Plant and animal viruses can enter through endocytosis, in which the cell membrane surrounds and engulfs the entire virus. Some enveloped viruses enter the cell when the viral envelope fuses directly with the cell membrane. Once inside the cell, the viral capsid is degraded and the viral nucleic acid is released, which then becomes available for replication and transcription.
The replication mechanism depends on the viral genome. DNA viruses usually use host cell proteins and enzymes to make additional DNA that is transcribed to messenger RNA (mRNA), which is then used to direct protein synthesis. RNA viruses usually use the RNA core as a template for synthesis of viral genomic RNA and mRNA. The viral mRNA directs the host cell to synthesize viral enzymes and capsid proteins, and to assemble new virions. Of course, there are exceptions to this pattern. If a host cell does not provide the enzymes necessary for viral replication, viral genes supply the information to direct synthesis of the missing proteins. Retroviruses, such as HIV, have an RNA genome that must be reverse transcribed into DNA, which then is incorporated into the host cell genome.
To convert RNA into DNA, retroviruses must contain genes that encode the virus-specific enzyme reverse transcriptase, which transcribes an RNA template to DNA. Reverse transcription never occurs in uninfected host cells; the needed enzyme, reverse transcriptase, is only derived from the expression of viral genes within the infected host cells. The fact that HIV produces some of its own enzymes not found in the host has allowed researchers to develop drugs that inhibit these enzymes. These drugs, including the reverse transcriptase inhibitor AZT, inhibit HIV replication by reducing the activity of the enzyme without affecting the host’s metabolism. This approach has led to the development of a variety of drugs used to treat HIV and has been effective at reducing the number of infectious virions (copies of viral RNA) in the blood to non-detectable levels in many HIV-infected individuals.
The last stage of viral replication is the release of the new virions produced in the host organism. They are then able to infect adjacent cells and repeat the replication cycle. As you have learned, some viruses are released when the host cell dies, while other viruses can leave infected cells by budding through the membrane without directly killing the cell.

Ferns have vascular tissue, an adaptation to life on land, but they have an ancestral reproductive trait that tends to limit them to moist habitats. What is it?
Answer:
The correct answer is - flagellated sperm.
Explanation:
In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.
Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.
