Answer:
light dependent reaction?
Explanation:
55. cytochemical stains were performed on bone marrow smears from an acute leukemia patient. the majority of the blasts showed varying amounts of myeloperoxidase positivity. some of the blasts stained positive for chloroacetate esterase, some were positive for alpha-naphthyl acetate esterase, and some blasts stained positive for both esterases. what type of leukemia is indicated? a. lymphocytic b. myelogenous c. myelomonocytic d. erythroleukemia
In the given question where cytochemical stains were performed on bone marrow smears from an acute leukemia patient, the type of leukemia indicated is Myelomonocytic leukemia.
Cytochemical diagnosis of acute myelomonocytic leukemia
In a third group, leukemic cells contain both esterase in the same cell, and this group is thought to represent "true" myelomonocytic leukemia.
Blood and bone marrow smears from adult patients with acute leukemia were stained for esterase reactions sequentially with naphthol AS D-chloroacetate (chloroacetate esterase) followed by alpha-naphthylbutyrate (non-specific esterase). Two substrates were specific for granulocytes and monocytes, respectively.
This method allows her to distinguish between three subgroups of acute nonlymphocytic leukemia. Leukemia cells can be positive for either chloroacetate esterase or non-specific esterase, and the authors suggest that these two subsets can be divided into 'true' granulocytic leukemia and 'pure' monocytic leukemia.
In the majority of patients in this group, leukemia developed from the preleukemia stage. Using Romanovsky-stained smears alone, the monocyte-like features and absolute increase in monocyte count in acute granulocytic leukemia may lead the leukemia to be misdiagnosed as acute myelomonocytic leukemia.
This occurred in 5 of the 13 cases in the study. The presence of granulocyte- and monocyte-specific esterase in single cells supports the notion of a common origin for granulocytes and monocytes.
The authors conclude that the combined esterase reaction can distinguish between acute granulocytic leukemia, acute monocytic leukemia, and acute myelomonocytic leukemia.

Show your work here using the data in Table 1 to calculate the energy consumed by this female sea otter:
Sea otters eat 25 percent of their body weight each day in the form of sea urchins, crabs, mussels, clams, snails and other invertebrates.
1 urchin that weighs around 15 grams provides 20 calories of energy.
So,
40 urchins = 800 calories of energy.
Similarly,
1 mussel = 146 calories of energy.
So,
12 mussels = 1752 calories of energy.
And,
1 crab = 381 calories of energy
So,
4 crabs = 1524 calories of energy
Hence, the total amount of calories consumed by the sea otter is equals,
= 4076 calories of energy per day approximately.
Female otter needs about 7,500 calories per day.
Therefore, the given diet does not satisfy this female otter's daily needs.

What is a chemical equation?
All plant and animal cells include the chemical compounds adenosine diphosphate and adenosine triphosphate, sometimes known as nucleotides.
A high-energy phosphate group is added to ADP to convert it to ATP for energy storage. The conversion occurs either in mitochondria, which are specialized energy-producing structures or in the cytoplasm, the fluid-filled space that lies between the cell membrane and the nucleus.
Adenosine diphosphate with inorganic phosphate plus energy results in adenosine triphosphate, which is the product of the conversion of ADP to ATP.

Every enzyme has a different specific heat.
The amount of heat needed to raise a substance's temperature by one degree Celsius in one gramme is also known as specific heat. Typically, calories or joules per gramme per degree Celsius are used as the units of specific heat. For instance, water has a specific heat of 1 calorie (or 4.186 joules) per gramme per degree Celsius.
The notion of specific heat was developed by the Scottish scientist Joseph Black in the 18th century as a result of his discovery that equal masses of different substances required varying quantities of heat to raise them through the same temperature range. The French scientists Pierre-Louis Dulong and Alexis-Thérèse Petit showed in the early 19th century that measurements of a substance's specific heat allow one to calculate its atomic weights.

A feedback mechanism is a physiological control system in a living organism that functions to bring the body back to its stable internal condition, also referred to as homeostasis.
When a change in the system results in an output, the feedback mechanism is activated. Chemicals, genes, and the regulatory relationships between them make form the biochemical control system in living things.
There are two types of feedback mechanisms; these are positive and negative feedback mechanisms.
When a change in one direction is followed by another change in the same direction, positive feedback loops develop.When a change in one direction results in a change in the other, negative feedback loops are created. For instance, feedback results from an increase in a substance's concentration, which lowers the substance's content. Mechanisms called negative feedback loops appear to be stable by nature.Feedback loop for dehydration.
A stimulus is reversed or turned off by negative feedback. Antidiuretic hormone, which acts to reduce urine production and enable the body to save fluids, is secreted when the body is dehydrated. Negative feedback stops the release of the antidiuretic hormone when the body's fluids are replenished.
