Explanation:
Natural selection is not random because it is based on fitness in the context of environmental conditions. This, more often than not, implies logical choices based on given external parameters. For example, if the weather remained cold, selection would go to those who are fit in the cold not those who are fit in the hot weather.

The neuronal serotonin reuptake transporter 5HTT1 is of great interest to the pharmaceutical sector. Your lab has recently isolated two compounds that bind directly to and act as inhibitors of serotonin uptake; these inhibitors have been named L2001 and L2002. Both L2001 and L2002 seem to reduce serotonin uptake 10-fold when added to cells individually. To characterize how L2001 works, your friend has discovered that L2001 does not affect the ability of 5HTT1 to bind serotonin, but instead seems to decrease the rate at which 5HTT1 is able to change its conformation. Another graduate student in the lab has been working on how L2002 affects 5HTT1 and has determined that L2002 acts in a manner consistent with its being a competitive inhibitor of 5HTT1 (i.e. competes with serotonin for its binding site). Given this information, would you predict that adding L2001 and L2002 together to cells would have a greater effect, a smaller effect, or no effect on 5HTT1 transport compared with the addition of only one of these inhibitors onto cells? Explain

Answer: (C) trees that have deep roots
Answers
The characteristic feature of an upland hardwood forest is : ( C ) Trees that have deep roots
An characteristic that makes a forest an upland hardwood forest is the presence of a tree canopy which covers more than 50% of the entire forest area emanating from various tree species present in the forest.
Hardwoods have deep roots which help them to get the necessary nutrients from the soil and this type of root system generally supports the structure of the trees overtime.
Hence we can conclude that The characteristic feature of an upland hardwood forest is Trees that have deep roots

What is found inside of ice core samples that scientists use to determine the composition of the atmosphere at the time the ice was formed?
A. Dust particles
B. Ions
C. Gas bubbles
D. microbes
Answers
A. and C.
Explanation:
Ice cores contain evidence of trace elements, gas bubbles, dust, pollen, even viruses and bacteria that can be traced back in time to yield vivid images of Earth's history and prehistory for those who learn to read them.
Gas bubbles are typically found inside ice core samples that scientists use to determine the composition of the atmosphere at the time the ice was formed. Thus, the correct option is C.
What is Atmosphere?An Atmosphere may be defined as a type of layer that significantly consists of numerous gases. It surrounds any celestial body like earth. The atmosphere of the earth is generally composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
During the time, when scientists formed the ice, gas bubbles of carbon dioxide, methane, and other greenhouse gases are significantly present inside the cores of the ice sample.
Apart from this, some sorts of bacteria, viruses, and other microorganisms are also visualized inside ice core samples.
In ancient times, the level of pollution is significantly low, so dust particles are not much highlighted in this region.
Therefore, gas bubbles are typically found inside ice core samples that scientists use to determine the composition of the atmosphere at the time the ice was formed. Thus, the correct option is C.

choose a plant or animal that you think is interesting. describe some of the threats or challenges
Answers
Answer:
If I were to choose an interesting plant or animal, I'd choose a "sloth."
Explanation:
A sloth is a mammal that can be found in tropical forests, particularly in the area of Central America and South America. It is a slow-moving animal (4 m/min. to be exact) that makes it prone to several dangers.
Its slow movement may allow predators to take advantage of it because it can never run or save its own life. It is truly helpless in the face of predators.It spends most of its time hanging in trees; thus, it needs trees for survival. If a wildfire would burn the forest down, then the sloths will be homeless. Being on the ground makes them useless, since their body is made for climbing.It is also prone to being electrocuted, since it often mistook electrical lines as branches of trees.How could a blood test reveal what foods a person has eaten?.

1-When you get sick, should you take an antibiotic that a friend or family member offers you (this includes your mom!)? Why or why not?
2- Let's say you're sick and your doctor prescribes you an antibiotic that you have to take for 7 days. If you feel better after 4 days, should you continue taking the antibiotic for the full dose, or stop taking it? Why or why not?
3-If you have a virus, will taking antibiotics cure your infection? Why or why not?
Answers
Answer:
1. No! You should only take antibiotics that your doctor prescribes. If you take the wrong antibiotics, or the antibiotics are not necessary, they will not make you feel better and they could contribute to antibiotic resistance by exposing populations of bacteria to antibiotics. This can lead to bacteria evolving resistance genes because of natural selection.
2. No. You must finish the course of antibiotics. By completing the treatment, you increase the odds of killing all the bacteria causing your illness. This means that there are no bacteria left that might develop resistance to the antibiotics
3, No, antibiotics only work against bacteria, and will not work against viral infections. They usually attack the bacterial cell wall, interfere with bacteria reproduction, or interfere with protein synthesis
