Which of the formed elements arise from myeloid stem cells?
a) B cells
b) natural killer cells
c) platelets
d) all of the above
Answer:
c
Explanation:
it creates platelets and a myeloblast, or monocytes
The formed elements that may arise from myeloid stem cells are platelets. Thus, the correct option is C.
How myeloid progenitor cells are formed?The myeloid progenitor cells are formed from the hematopoietic stem cells which are of multipotent nature. Such HSC cells induce the transcription factor GATA-2 and give rise to myeloid progenitor cells.
The process of hematopoiesis occurs in the bone marrow in which HSCs play a major role in synthesizing the blood cells.
The myeloid progenitor cell further produces dendritic cells through the transcription factor FLT3L, eosinophils through IL-5, mast cell, platelets through thrombopoietin, RBCs through erythropoietin, etc.
Therefore, among the given options, platelets are derived from myeloid stem cells. Thus, the correct option is C.

Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Remember hydrophilic will color those areas that "like water", think about water`s relationship with fats).
Answer:
The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.
Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.
What do producers dictate in
an ecosystem?
A. the size of the organisms
B. the age of the organisms
C. the amount of organisms
Answer:
C. The amount of organisms
Explanation:
Producers produce food from inorganic matter, this then makes food for other organisms in an ecosystem. The amount of producers dictates how much food is available, and by that how many organisms can be present.

Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydrates in living organisms. The most important carbohydrate is glucose that is metabolized by all living cells in the first energy-yielding pathway known as glycolysis.
Use your knowledge of glucose for carbohydrate metabolism to select the term that best completes each sentence.
The glucose conversion to_________ opens anaerobic and aerobic metabolic pathways. ________in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the The TCA cycle. converts lactate to glucose and returns the glucose molecule to the muscles through
In the Cori cycle, the release of energy from_________ the process of anaerobic glycolysis.
Answer:
The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.
Explanation:
In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).
In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.
The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.
VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.
In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.

Why does the body respond to stimuli
Answer:
That is because of Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Hope this helped
All the best !!
The body typically responds to stimuli because of the function of the receptors.
How does the body of an organism respond to stimuli?The organism significantly responds to the stimuli by means of a number of effectors, such as muscles and glands. Energy is generally used in the process in order to facilitate an ideal function of the entire body and maintain homeostasis.
Due to this, the organisms change their behavior in response to changes in the surrounding environment. For example, an organism may move in response to its environment.
The process of responding to stimuli is generally mediated by the receptors which are the groups of specialized cells within the body. These receptors alter their physiology and function with respect to the surrounding environment and detect a change. In the nervous system, this directs to an electrical impulse being made in response to the stimulus through a chemical process.
Therefore, the body typically responds to stimuli because of the function of the receptors.
