Answer:
Introduction
Cellular respiration is one of the most elegant, majestic, and fascinating metabolic pathways on earth. At the same time, it’s also one of the most complicated. When I learned about it for the first time, I felt like I had tripped and fallen into a can of organic-chemistry-flavored alphabet soup!
Luckily, cellular respiration is not so scary once you get to know it. Let's start by looking at cellular respiration at a high level, walking through the four major stages and tracing how they connect up to one another.
Steps of cellular respiration
Overview of the steps of cellular respiration.
1. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made. These reactions take place in the cytosol.
2. Pyruvate oxidation. Pyruvate travels into the mitochondrial matrix and is converted to a two-carbon molecule bound to coenzyme A, called acetyl CoA. Carbon dioxide is released and NADH is made.
3. Citric acid cycle. The acetyl CoA combines with a four-carbon molecule and goes through a cycle of reactions, ultimately regenerating the four-carbon starting molecule. ATP (or, in some cases, GTP), NADH, and FADH_2 are made, and carbon dioxide is released. These reactions take place in the mitochondrial matrix.
4. Oxidative phosphorylation. The NADH and FADH_2 produced in other steps deposit their electrons in the electron transport chain in the inner mitochondrial membrane. As electrons move down the chain, energy is released and used to pump protons out of the matrix and into the intermembrane space, forming a gradient. The protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain by electron carriers \text{NAD}^+NAD

John Terborgh, tropical ecologist at Duke University, asserts that in order to save tropical forests, citizens of industrial nations are going to have to pay developing countries. Do you agree
Answer:
I do agree
Explanation:
As a personal opinion, I do agree with this statement. Citizens of developing countries use these rain forests for many reasons. One of which is for survival they cut down and use what they need in order to gather the resources that they need and build their habitats. This goes slowly destroying the rainforests. The other reason is that these citizens many times sell the rights to the rainforest land to mining companies that ultimately destroy the rainforest for its resources. The only way to prevent both of these from happening is by paying these developing countries to protect the rainforest instead of profiting from it.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I
Answer:
This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.
Explanation:
During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

When increasing the size of muscles or building muscle mass ____________. Group of answer choices muscle soreness indicates the muscles are growing delayed onset muscle soreness indicates the muscles are growing lactic acid build up triggers muscles to grow micro tears signal the muscles to grow
Answer:
A. soreness indicates the muscles are growing
D. micro tears signal the muscles to grow
Explanation:
Muscle soreness is one of the indication of muscles are growing as while doing exercise, some inflammation takes place to get bigger and stronger muscles. Some pain signals are sent by the body to make it feel soreness after intense exercise.
Micro tears signal also indicates muscles growth as after intense workout, a certain amount of soreness is felt by our body and these micro tear signals to repair and replenish the muscle tissue that eventually accumulate to form muscle mass.
Hence, the correct answers are: "A. and D.".

The formation and action of angiotensin II can be summarized as follows: It is synthesized either when blood pressure is ____________ or the ____________ division is activated. It causes a(n) ____________ in resistance, ____________ in fluid output (which helps to maintain blood volume and blood pressure), and an increase in blood ____________ (if fluid intake occurs
Answer:
low, sympathetic, an increase, decrease, pressure
Explanation:
Angiotensin II is a peptide hormone whose primary function is to increase blood pressure by different mechanisms of action including vasoconstriction and sympathetic nervous stimulation. This hormone is produced by the action of the enzyme angiotensin-converting enzyme (ACE). Angiotensin II may act on the central nervous system (CNS) to increase antidiuretic hormone (ADH) levels, and on the arterial smooth muscle cells to trigger vasoconstriction. Angiotensin II induces the release of ADH and aldosterone hormones in order to increase blood pressure. When blood pressure returns to normal values, circulating Angiotensin II levels are decreased by negative feedback.

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Answer:
I so I am also a bit confused, but I hope this could answer your question!
Explanation:
The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine. The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.
The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.
This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.
