Answer:
Decrease in competition from other plants.
Explanation:
Decrease in competition from other plants is the environmental factors likely leaf to the exponential growth seen in fireweed after the Yellowstone wildfires because decrease in population from other plants will lead to a particular species dorminating a particular geographical area and this dorminating species are Dorminant when competition has been reduced by wild fire and this will lead to exponential growth where the available resources will be abundance or unlimited or resources increases.
Carbohydrates are composed of carbon, hydrogen, and oxygen. What specific chemical difference distinguishes carbohydrates from other large organic molecules?
Carbohydrates contain a large number of oxygen atoms which makes them different from rest of the organic molecules.
What are carbohydrates?A carbohydrate is a biomolecule composed of carbon, hydrogen, and oxygen atoms in a 2:1 hydrogen-oxygen atom ratio.
Carbohydrates are the chief source of energy in the body, fueling the brain, kidneys, heart muscles, a s well as central nervous system.
Fiber, for instance, is a carbohydrate that aids digestion, makes person feel full, and helps keep blood cholesterol levels in check.
Carbohydrates differ from the rest of the organic molecules in that they contain a large number of oxygen atoms.
Thus, carbohydrates can serve the very different functions of energy storage and structural support and protection due to differences in molecular structure.

Use the diagram and scenario to answer the constructed response question. Marcus recently visited his doctor with complaints of nausea, stomach cramps, bloating, and gas that occur approximately 45 minutes after eating ice cream, cheese, or drinking milk. The doctor’s report indicated that Marcus has an increased production of acidic toxins causing him to have an imbalanced intestinal pH. The doctor concluded he is lactose intolerant. Using claim, evidence and reasoning (CER) format, determine the macromolecule represented by lactose and describe what happens in the body when a person drinks milk, which contains lactose. You must use the terms lactose, lactase, glucose and galactose in your response. (Hint: Use the picture to explain the process.)

In humans, red blood cells are the only cells that eject their nuclei as they develop. By emptying themselves of nuclei, these cells are able to do
which of the following?
replace themselves quickly when more cells are needed
transport greater amounts of oxygen and waste throughout the body
transmit electrical impulses quickly
attack bacterial pathogens more effectively
Answer:
Transport greater amounts of oxygen and waste products.
Explanation:
Not having nuclei allows the red blood cells (RBCs) to have more space for haemoglobin (Hb). Haemoglobin is the oxygen-carrying pigment in the RBCs. So more Hb means more oxygen transport.
Hb also carries carbon dioxide, a waste product.
In humans, red blood cells are the only cells that eject their nuclei as they develop, so by emptying themselves of nuclei, these cells are able to transport greater amounts of oxygen and waste throughout the body, which is the second option.
What is the function of red blood cells in humans?The human and other vertebrates have different types of blood cells, and in humans there are white blood cells and red blood cells. In red blood cells, there is no nucleus when the cell gets mature, so the red blood cells get hemoglobin at that place to carry most of the oxygen through the body and remove the carbon dioxide.
Hence, in humans, red blood cells are the only cells that eject their nuclei as they develop, so by emptying themselves of nuclei, these cells are able to transport greater amounts of oxygen and waste throughout the body, which is the second option.

Starting with a protein that has been inserted into the Endoplasmic reticulum (ER) membrane with the Amino (N) terminal in the ER lumen and the carboxy (C) terminal in the cytoplasm, describe the journey the protein will take until it is placed in the plasma membrane. Include any modifications that occur during the journey and where they occur. Also, always indicate where the N and C terminal are located.
Answer and Explanation:
Ribosomes are the primary structure for protein synthesis. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
Free ribosomes are not attached to any cytoplasmic structure or organelle. They synthesize proteins only for internal cell use. Other ribosomes are attached to the membrane of the endoplasmic reticulum and they are in charge of synthesizing membrane proteins or exportation proteins. Free and attached ribosomes are identical and they can alternate their location. This means that although free ribosomes are floating in the cytosol, eventually, they can get attached to the endoplasmic reticulum membrane.
Synthesis of proteins that are destined to membrane or exportation starts in the cytoplasm with the production of a molecule portion known as a signal aminoacidic sequence. This signal sequence varies between 13 and 36 amino acids, is located in the amino extreme of the synthesizing protein, and when it reaches a certain length, it meets the signal recognizing particle. This particle joins the signal sequence of the protein and leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building. When they reach the membrane of the endoplasmic reticulum, the signal recognizing particle links to a receptor associated with a pore. Meanwhile, the ribosome keeps synthesizing the protein, and the enlarged polypeptidic chain goes forward the reticulum lumen through the pore. While this is happening, another enzyme cuts the signal sequence, an action that requires energy from the ATP hydrolysis. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen. Here it also happens the protein folding (which is possible by the formation of disulfide bridges of proteins are formed) and the initial stages of glycosylation (the oligosaccharide addition).
Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are packaged into vesicles and sent to the Golgi complex, where it occurs the final association of carbohydrates with proteins. The Golgi complex sends proteins to their different destinies. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organelle. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
There are certain signal sequences in the carboxy-terminal extreme of the protein that plays an important role during the transport of membrane proteins. A signal as simple as one amino acid in the c-terminal extreme is responsible for the correct transport of the molecule through the whole traject until it reaches the membrane.

n the healthcare setting, “alcohol” refers to two water-soluble chemical compounds—ethyl alcohol and isopropyl alcohol—that have generally underrated germicidal characteristics 482. FDA has not cleared any liquid chemical sterilant or high-level disinfectant with alcohol as the main active ingredient. These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores. Their cidal activity drops sharply when diluted below 50% concentration, and the optimum bactericidal concentration is 60%–90% solutions in water (volume/volume) 483, 484.

Explanation:
We did not use a control group in this experiment. What is the purpose of the control group and how could we have set up with one for this experiment?
Answer:
The experiment will be faulty
Explanation:
To set up a control group, you pick individuals at random( so you don't just get a group to be of the same character, or opinion).
The control group is vital in every experiment because, sometimes our hypothesis could be mere coincidence or assumptions. So the control group will be compared to the test group to see if the results are correct. Plus look at it this way, without a control group, your hypothesis wouldn't be a theory.
