Answer:

Explanation:
These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the former relies on manually removing the woods, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the woods but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide
1. Which of the following is the likely reason the weed has remained?
a. The weed needed to be resistant in order to survive, so it became resistant
b. A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
2. Which of the following is likely to happen if that weed stays in place?
a. The trait will spread to nearby weeds
b. The weed will survive long enough to reproduce
c. In time, the herbicide will no longer be effective on that field.
Answer:
1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )
2) The weed will survive long enough to reproduce ( B )
Explanation:
1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now
2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce
The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation

Which of the following biotic factors is associated with increasing the capacity of the organisms to move across fragmented landscapes? Patch size, connectivity,Patch shape, Distance from other landscape patches
Answer:
connectivity
Explanation:
Natural and anthropogenic alterations affect the landscape. The unmeasurable use of the land for farming, cattle industry, buildings, among many other activities, has caused a severe fragmentation in the original landscape that has been seriously affecting biodiversity.
Fragmentation occurs when a big extension is transformed into many different and smaller patches, separated by another type of cover. You can imagine, for instance, an area used for mono-culturing, which you can see as a homogeneous space of the same texture and color, and small green islands of original vegetation dispersed in this cropped area. These small islands are separated from each other by the crop.
These alterations produce patches or tesserae in the landscape. Patches are relatively homogenous areas with well-defined borders and environmental characteristics very different from those of the surrounding areas. These are like islands. You can think about patches or tesserae as the remaining pieces or units of the original landscape dispersed inside an affected bigger-sized area.
Fragmentation generates a significant loss of physical continuity between the different areas of the original habitat. It might negatively affect biodiversity by decreasing patch sizes, completely isolating them from each other, and increasing the border effect.
Many species can not survive if they are not in the original habitat. Probably they do not find enough food or shelter, or they are very exposed to predation. So they need to stay in the patch. Most of these species are not even adapted to living on the border of the patches. Eventually, fragmented areas can not support some population species that end by dying because they can not survive for a long time in that reduced place. Patches are not suitable to support too many species.
For these reasons, the connection between islands becomes so important. To allow species to move from one place to the other, interact with other species, reproduce, find food, shelter, avoid predation. In other words, survive. Connectivity is how the territory makes possible individuals flow or genetic flow, between the different tesserae.

As a discussed in the lesson, eukaryotic cels are differ from prokaryotic cells based on what three things?
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions
The ability to taste PTC comes from the presence of a dominant allele (T). A population of 20 individuals was surveyed to determine whether or not they could taste PTC. Sixteen out of the twenty surveyed could taste PTC. Four could not taste PTC. Assume that Hardy-Weinberg Equilibrium conditions are met in the population. Round all answers properly to 2 decimal digits. Rounding rules: When rounding to 2 decimal digits, look at the third decimal digit. If the third digit is 5 or greater, round up. If the third digit is less than 5, round down.

What is a genotype?
A genotype is someone's collection of genes. The word also can guide the two alleles inherited for a respective gene.
The genotype is defined when the information encoded in the genes' DNA is used to make protein and RNA molecules.

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels. This is so organs like the brain that use primarily glucose as their carbon source to produce energy via ATP have a steady supply of glucose. It also ensures that the levels of glucose in the blood stream do not get too high. Using the plots from problem 6, discuss why it makes sense that glucokinase in liver would behave differently than the hexokinase in other cells.
Answer:
Due to difference in function.
Explanation:
Glucokinase in liver behave differently than the hexokinase in other cells because glucokinase performs different function in the body. Glucokinase is an enzyme that is responsible for sensing the glucose level in the blood and also plays a key role in the storing of glucose as glycogen while on the other hand, this storing ability is absent in hexokinase so that's why the glucokinase in liver behave differently than the hexokinase in other cells.

nocturnal mean awake during the day, and use the light to their advantage.
diurnal means active at night
Answer:
diurnal means awake during the day, and use the light to their advantage
nocturnal active at night.
Explanation: Diurnal means active during the day, such as a mosquito meanwhile, a nocturnal animal or being is only active during the night, and sleeps the day away, such as a bat
Hope this helps ^^
Diurnal means awake during the day time, and use the light to their advantage. Nocturnal means active at night time. Thus, the correct options will be A and B.
What is Diurnal and Nocturnal?Based on the activeness of an organism during a day or 24 hours time period, the animals or organisms can be classified into two different types which are nocturnal and diurnal organisms. Nocturnal animals are the animals which are most active during the night time, and diurnal animals are the animals which are active during the daytime.
Diurnal animals are those animals which are awake during the day time, and use the light energy to their advantage. Nocturnal animals are the animals which are active at the night time.
Therefore, the correct options will be A and B.

Neurons of the cerebral cortex never dip into the medulla.
O True
O False
Answer:
False
Explanation:
The cerebral cortex refers to the outer layer of the brain. This layer is formed by a thin film of nervous tissue that surrounds the surface of the cerebral hemispheres, with primates having a much more developed cerebral cortex than other animals.
the cerebral cortex is a thin layer of neurons and neuronal connections which is embedded in the neocortex(the neuronal cells of the cerebral cortex which form in the deep layer), it is not homogeneous, since it is made up of six layers of cells, each with specific and specific functions.
