The Investigation
It’s your first day shadowing a detective, and already it’s been interesting…if you can call the murder of a young woman interesting. You’ve been trying to detach yourself by reading the file, but you have interviews later this morning and you’re nervous. Going back to the file, you jot down some notes on what you know so far.
Melissa was a 35-year-old nurse-midwife with over ten years’ experience delivering babies both in hospitals, as well as in homes when risk for complications were low. She was healthy; her only medical condition was an allergy to bee stings. The body was discovered by her boyfriend when he came over for a planned dinner. The dinner – spaghetti – was laid out, but no cooking had begun. There was also a plate of cupcakes, with a bite out of only one of them. The boyfriend said Meleea had not mentioned feeling unwell when they spoke earlier in the day. She was, however, tired, and understandably upset about a long birth she had assisted with where a mother had died in childbirth.
The medical examiner did not have results yet, so you sketch out some questions you have for the interviewees.
1. Who would you interview, and what would you ask?
2. Do you have any hypotheses about what happened to Meleea? Write at least one or two possibilities.
1. I would interview the boyfriend and family members of the mother who died in childbirth. I would ask where they were at time time of death and if they have an alibi.
2. There could have been something put in the cupcakes, since only one bite was taken from a single one.
What do you think might happen to tissues such as the intestinal lining if a disorder blocked mitotic cell division in all cells of the body
Answer:
This is what actually happens with chemotherapy for cancer. Drugs are given which inhibit cell division. Cells such as tumour cells, which are rapidly dividing are affected most, then other dividing cells such as the epithelial lining of the gut, which nedds cell division to repair itself. The result is ulceration and bleeding.

Answer:
The correct answer is - 3 × 10⁻²
Explanation:
first find LKo = length of BDNA/ 10.5 bp/turn
= 4200/10.5
= 400
now calculate Δ LK= LK - LKo
ΔLK = 412-400
ΔLK = 12
now, superhelix density = ΔLK/LKo
⇒ 12/400 = 0.03
= 3×10⁻²
Thus, the correct answer is - 3 × 10⁻²

A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland?
Answer:
Explanation:
Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
Answer:
An increase in gene flow between the birds population.

. Some people have developed allergies to animal insulin. Explain why the immune system would be able to distinguish animal insulin from human insulin
Answer: Difference between animal and human insulin and/or not being properly purified.
Explanation:
Insulin is a hormone that regulates the metabolism of secreted by the β-islet of Langerhans cells of the pancreas. It that allows blood sugar, known as glucose, to pass into cells. Glucose comes from the food and drinks and it is the body's main source of energy. So, insulin plays a key role in maintaining proper blood glucose levels.
Animal insulin is produced by the pancreas of animals, usually cows and pigs. Then, the insulin is purified to reduce the chance of the insulin user developing a reaction to the insulin.
Each organism has its own genetical identity and any foreign particle is treated as an antigen. And, there is small chemical difference between insulin produced in animals and insulin produced in humans. That difference, caused by a different sequence of peptides, can be recognized by the immune system as something foreign and as such can be a threat to the body. And that would trigger an immune response. Also, the response can be because it hasn't been properly purified and contains other compounds or proteins that are also foreign.

what is a part of interphase A. cytokinesis B. telophase C. anaphase D. s phase
Answer:
D
Explanation:
I did it on my own soci know it's the answer
In the context of interphase, the S phase is the specific part where DNA replication occurs, contributing to the overall process of cell division and ensuring the transmission of genetic material to new cells and the correct option is option D.
Interphase is the longest phase of the cell cycle, and it is divided into three main stages: G1 phase, S phase, and G2 phase. Among these stages, the S phase is specifically responsible for DNA replication. It is during the S phase that the cell's DNA is duplicated in order to prepare for cell division.
During the S phase, the DNA helix unwinds, and the two strands separate. Enzymes and proteins then work together to synthesize new complementary strands for each of the separated DNA strands. As a result, two identical copies of the DNA molecule are produced.
The S phase plays a crucial role in maintaining the genetic integrity of the cell. By accurately duplicating the DNA, the cell ensures that each daughter cell formed during cell division receives an identical set of genetic information. This is vital for the proper functioning and development of organisms.
Thus, the ideal selection is option D.

Which of the following best describes how ACh changes the ion permeability of the sarcolemma?
A) ACh activates acetylcholinesterase.
B) ACh entry into the axon terminal causes neurotransmitter release.
C) ACh binds to receptors in the junctional folds.
D) ACh entry into the muscle fiber causes Ca2+ to be released by the sarcoplasmic reticulum.
Answer:
C) ACh binds to receptors in the junctional folds.
Explanation:
The statement 'ACh binds to receptors in the junctional folds' best describes how ACh changes the ion permeability of the sarcolemma (Option C).
The sarcolemma is the plasma membrane of the muscle cells.
Moreover, acetylcholine (ACh) is a neurotransmitter that is released by motor neurons during muscle contraction.
After release, ACh binds to specific (nicotinic) receptors in the sarcolemma at the neuromuscular junctions (i.e., junctional folds).
These receptors are also called chemical-gated and/or ligand-gated channels because they are known to modify the ion permeability of the sarcolemma.
In conclusion, the statement 'ACh binds to receptors in the junctional folds' best describes how ACh changes the ion permeability of the sarcolemma (Option C).
