what is one of the largest crops grown in the united states today, and a staple or core food in many first people/native american dishes?
Maize (Corn) is one of the largest crops grown in the united states, and a staple food in many first people/Native American dishes.
In the United States, a third of corn production is utilized to feed livestock like cattle, hogs, and chickens. Corn supplies the "carbs" and soybeans the protein in animal feed. According to some estimates, a beef cow grown on a feedlot can consume a ton of corn; two bushels of American maize are required to produce one serving of corn-fed steak. Cows that produce milk and beef both eat silage, which is made of fermented corn stalks and other green plants. A little over a third of corn production is utilized to produce ethanol, which is added to gasoline as a sustainable fuel. The Renewable Fuel Standard calls for 10% of gasoline to be renewable fuel, however, in some places, notably in the Midwest, you can get E15 (15 percent ethanol) or E85 (85 percent ethanol). The remaining corn harvest is either exported to other nations for use as food or feed, or it is used in the United States for industrial purposes, drinks, and human nourishment. There are many uses for corn. It is employed in the production of biodegradable packaging materials, tortilla chips, grits, canned beer, soda, and cooking oil. It is a crucial component of the growing medium used to produce life-saving medications like penicillin. To keep weeds from growing in flower beds, use corn gluten meal.

The trait is controlled by a recessive gene. It refers to a characteristic that only be seen in homozygous individuals, hidden by other inherited qualities but survives in populations of heterozygous individuals.
When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest. This is in contrast to a dominant characteristic, which can only be expressed when one of the two alleles is present.

Answer:
After the drought, there was very little water and many plants died, so the remaining environment was mostly brown. Because of this, having brown coloration was a favorable adaptation for frogs. The brown frogs are the ones that survived and reproduced, causing the number of brown frogs to increase. Having green coloration, on the other hand, was an unfavorable adaptation because they were unable to blend in with the surrounding environment. They became less likely to survive and reproduce, causing the number of green frogs to decrease.

The response options in this group are typically noncovalently linked to the membrane lipids that compose peripheral membrane proteins.
What is Peripheral membrane proteins ?Extrinsic membrane proteins, also known as peripheral membrane proteins, are membrane proteins that are connected with biological membranes but only briefly bind to those membranes. These proteins either bind to integral membrane proteins or pierce the lipid bilayer in the periphery.
Directing and maintaining the internal cytoskeleton and elements of the extracellular matrix are two of the primary functions of peripheral proteins. Organelles, filaments, and tubules work together to create both of these structures.
Proteins that only associate with the membrane through electrostatic or hydrophobic interactions (Caldalkalibacillus thermarum type-II NADH dehydrogenase as an example) and proteins that anchor themselves in the lipid bilayer using a hydrophobic segment are two subtypes of peripheral membrane proteins.
What is lipid bilayer ? A thin polar membrane comprised of two layers of lipid molecules is known as a lipid bilayer. These membranes are flat sheets that surround every cell in a continuous barrier.The lipid bilayer serves as a barrier, retaining ions, proteins, and other molecules where they are required while preventing their diffusion into unintended locations.The creation of membrane microdomains that are helpful for biological processes depends on how a lipid bilayer moves between its two primary phases, the liquid crystalline phase (L) and the gel phase (L), during a transition.To know more about Peripheral membrane proteins please click here ;

Photosynthesis is a process during which plants synthesise sugar using chlorophyll molecule and further this chlorophyll molecule along with mitochondria uses the sugar and convert it to energy molecule ATP.
1. The Calvin cycle receives ATP and NADPH from the light reactions and gives back ADP, Pi, and NADP+ to the light processes.
2. A magnesium ion stabilises the chlorophyll molecule at the core of the porphyrin ring and sends electrons down an electron transport chain to power the photosynthetic reaction.
3. water
4. Light hits PS2 and pigment molecule absorbs energy and gets excited to release electron. The electron is taken by the primary electron acceptor. Enzyme separates water into H+ (the two electrons) and O-, and supplies p680 with the electrons (strong oxidising agent). H+ is discharged into the thylakoid space, and oxygen from a split water molecule joins with another oxygen to produce O2.Photoexcited electrons travel from PS2 to PS1 through ETC. In PS1, electrons move to a lower energy level, supplying ATP with energy. As they descend, their energy pumps H+ into the chemiosis-related thylakoid luman. The electron in PS1 reaction complex P700 is excited by light energy that has been transferred there. After the electron passes through a second ETC, NADP+ reductase adds an electron, converting NADP+ into NADPH.
