what is one reason the membrane proteins could not go where the Davidson Danieli model thought they should go sandwiching the lipid membrane and either side 
One reason the membrane proteins may not go where the Davidson-Danielli model predicted is due to the fluidity and dynamic nature of the lipid membrane.
This model assumed that the lipid membrane was static and that proteins were fixed in their positions. However, it is now understood that the lipid membrane is constantly in motion, with lipids and proteins able to move laterally and even flip-flop between the two leaflets of the membrane.
As a result, membrane proteins may not be fixed in the locations predicted by the Davidson-Danielli model and may instead be more distributed or even inserted into the lipid bilayer.
Additionally, the Davidson-Danielli model did not account for the diversity of membrane proteins and their different structural and functional properties, which can also influence their localization within the membrane.

Describe a food chain in detail. Use the teacher notes to help you. Must be 2-4 sentences with a complete description of a food chain and the types of organisms in that food chain. Please check spelling and grammar before submission.
A food chain illustrates how nutrients and energy move through an ecosystem. Energy is first produced by plants at the most fundamental level, and then it is used by higher-level species like herbivores.
Energy is then transmitted from one carnivore to the next when they eat the herbivores. Every living species is a part of several different food chains. For instance, grass is a part of the chain that includes grass, grasshoppers, frogs, snakes, and eagles, as well as the chain that includes grass, deer, and tigers. A food web is made up of all the linked and overlapping food networks in an environment.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Each organism in a food chain is at a particular trophic level, which is determined by how many energy transfers distance it from the chain's initial energy source.
A food chain is a trophic level or linear succession of creatures that represents producers to top consumers along which the movement of nutrients and energy occurs when one organism consumes another.

The mutation is in the third position of the first codon, where "C" replaced "A", resulting in the codon "UAC" instead of "AUC".
What is a mutation?A mutation is a change that occurs in the DNA sequence of an organism. It can be caused by errors during DNA replication, exposure to mutagens such as radiation or chemicals, or spontaneous changes that occur over time.
Considering the given mutated DNA sequence:
mRNA sequence: AUG UGG ACC UGA CUA
Amino acid sequence: Met Trp Thr Stop Leu
The effect on the protein depends on the specific amino acid that is affected by the mutation. Referring to the chart, the codon "AUC" codes for the amino acid Isoleucine (Ile), and the mutated codon "UAC" codes for Tyrosine (Tyr). Therefore, the mutation results in a substitution of Isoleucine with Tyrosine at the first position of the polypeptide chain.

The nervous system and endocrine system play important roles in helping the body maintain homeostasis. The nervous system processes input when something is out of its optimal range. The nervous system can then determine the best course of action to correct the imbalance. Sometimes the nervous system stimulate the glands of the endocrine system to release hormones and other times, it can cause a response such as shivering or sweating to help return the body to its steady state. Calcium is a crucial nutrient used in many bodily processes from muscle contraction to blood clotting. The nervous and endocrine system work hand in hand to control calcium levels throughout the body.
Answer: The endocrine and nervous systems help detect changes in either the internal or the external environment and respond to those changes. Organ systems use feedback mechanisms to maintain homeostasis. Negative feedback is a control system that helps the body maintain homeostasis by sending a signal so stop a response.

When someone is admitted to the hospital, one of the first procedures health-care professionals perform is a blood draw. One lab value checked is a white blood cell (WBC) count. If the WBC count is elevated (normal range 4 4,000–11,000/mm3), this could indicate the presence of inflammation. Further analysis (called a differential) is performed to determine the relative prevalence of different types of white blood cells and the potential cause of the inflammation. What might be causing the inflammation if lymphocytes were elevated? Explain your reasoning.
If lymphocytes are elevated in the differential analysis of a blood sample, it could indicate the presence of a viral infection, such as mononucleosis or the flu.
What are lymphocytes and what are the causes of the elevation in their levels?Lymphocytes are a type of white blood cell that plays a critical role in the body's immune response to viral infections. When the body is infected with a virus, the lymphocytes become activated and increase in number to fight off the infection.
Other possible causes of elevated lymphocytes include bacterial infections, autoimmune diseases, and certain types of cancer, such as leukemia and lymphoma. However, in most cases, an elevated lymphocyte count is associated with viral infections.
