Answer:
If the populationsl of producers in an ecosystem became unstable the energy flow into the food web would decrease or increase along with changing populations of producers.
Answer:
Answer: option D.
Explanation:
Hey, there!
Reason: The reason is, when the number of producers are unstable, the flow to enegry from abiotic components to biotic components will be destructed. There will not be proper flow of enegry in whole ecosystem, which usally changes the flow of enegry as per the number of producers.

Any liquid that destroys bacteria is in the most household cleaning solutions like Lysol
Answer:
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.

what is excretion,list the ecretory product for mammals and indicate where each product is formed,make labelled of the nephron of a mammal
Explanation:
The mammalian kidney is a compact organ with two distinct regions: cortex and medulla. The functional unit of the kidney is the nephron. Each nephron is a tubular structure consisting of four regions. It arises in the cortex as a small vesicle about one-fifth of a millimetre (0.008 inch) in diameter, known as Bowman’s capsule, into which projects a tuft of capillary blood vessels, the glomerulus. Bowman’s capsule is continuous with the proximal convoluted tubule, which also lies in the cortex. Following the proximal convoluted tubule is the loop of Henle, which descends into the medulla and then runs straight up again to the cortex where it continues as the distal convoluted tubule. A collecting tubule, into which several nephrons open, courses through the medulla to open a wide cavity, the pelvis of the kidney. From the pelvis the ureter leads to the bladder, and from the bladder the urethra leads out of the body.
Is the Earth an open, closed, or isolated system? Explain.
Answer:
Closed Systems. The earth system as a whole is a closed system. ... Virtually no mass is exchanged between the Earth system and the rest of the universe (except for an occasional meteorite). However, energy in the form of solar radiation passes from the Sun, through the atmosphere to the surface.
Explanation:
Answer:
The earth is a closed system because only energy is naturally transferred outside the atmosphere.
Explanation:
A closed system is a system in which only energy is transferred with its surroundings. An open system, however, is a system in which both energy and matter can transfer.

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.

In a honeybee colony the queen stores sperm from male bees, or drones. She then lays thousands of eggs and uses the stored sperm to fertilize them and create offspring. Even when the stored sperm runs out, offspring drones are born in the hive. How is this possible? A) The unfertilized eggs became drones through regeneration. B) The unfertilized eggs became drones through fragmentation. C) The unfertilized eggs became drones through binary fission. D) The unfertilized eggs became drones through parthenogenesis
Answer:
D
Explanation: Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization by sperm. In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. In plants parthenogenesis is a component process of apomixis.

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.
