The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop

Answers

Answer 1

Answer:

Negative feedback.

Explanation:

The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

Answers

Answer:

Astrocytes are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.

Cell bodies of unipolar neurons are insulated from adjacent cell bodies by satellite cells.

The ventricles of the brain are lined with ependymal cells, which form an epithelial layer that is permeable to cerebrospinal fluid.

The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called microglia.

The myelin sheath of the Central Nervous System is formed by oligodendrocytes.

Axons of unipolar neurons are insulated by Schwann cells, which increase the speed of the electrical impulse.  

Explanation:

The neuroglia cells are a group of specialized cells that are in the Central and Peripheral Nervous System.

Astrocytes are star-shaped cells that maintain homeostasis in the nervous tissue. They also are part of the blood-brain barrier controlling what can enter the brain and whatnot.

Satellite cells are in the Peripheric Nervous System. They are around neurons and provide nutrients and insulation to neurons.

Ependymal cells are in the Central Nervous System. They line the ventricles and spinal cord's central canal. They are the ones that help in the production and circulation of the cerebrospinal fluid (CSF). They are part of the blood-cerebrospinal fluid barrier, keeping the cerebrospinal fluid clean, and they also absorb the CSF.

The microglia are the macrophages of the Central Nervous System. They phagocytize any pathogen that they detect in the CNS, protecting the neurons.

The myelin sheath is formed by the oligodendrocytes in the CNS and by the Schwann cells in the PNS. Their function is to insulate the axons so that the electrical impulse can travel through them.

All organisms must regulate by turning genes on and off in different cells at different times.

a. True
b. False

Answers

Answer:

a. True

Explanation:

The genome can be defined as the complete set of genetic information of an organism which is responsible to produce all the biological components required to carry out its metabolic functions (i.e., development, growth, reproduction, etc). These genes are transcriptionally expressed to produce mRNAs which are subsequently used to synthesize specific proteins (i.e., enzymes and structural proteins) by the process of translation. All organisms (i.e., either unicellular or multicellular organisms) exhibit specific gene expression programs by which such genes are regulated over time. Within the cell, gene regulation is essential to carry out biological processes ranging from development and differentiation to cell cycle arrest. These gene expression programs are acutely regulated via genetic (e.g., transcription factor binding) and epigenetic (e.g., DNA methylation) mechanisms, which work together in order to turn on/off genes during development.

chestnuts grow in regions prone to fires.
most forestry professionals no longer want to grow chestnuts.
new growth is stricken with the blight before it has the chance to mature.

Answers

Answer: New growth is stricken with the blight before it has the chance to mature.

Explanation:

American Chestnut trees can indeed regrow from their roots but due to the devastating effect of the chestnut blight, they have been unable to do this since the blight spread across the country.

The blight was introduced when Chinese chestnut trees were imported into the U.S. in the 20th century. It killed off most of the chestnut trees in the U.S. and attacks the tree again when it grows to around 6 meters bringing it down to its roots. This is why the American Chestnut is considered endangered.

A 66-year-old man has difficulty controlling voluntary movements. He can clearly state what he intends to do, describe how he would do it, and initiate or stop the movement. However, he has poor coordination and often misses his target. If his difficulty arises from a defect in one particular area of the central nervous system, which area is most likely to be involved

Answers

Answer:

Cerebrum

Explanation:

Cerebrum is the part of central nervous system that is responsible for the voluntary movement. If there is poor coordination between cerebrum and the muscles so the person has difficulty in controlling his voluntary actions or movement. Somatic nervous system is a part of the peripheral nervous system responsible for the voluntary movements of body parts through the use of skeletal muscles so we can say that both cerebrum and somatic nervous system is responsible for voluntary actions.

Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure.
An advantage of using synthetic fertilizer instead of organic fertilizer is that
A synthetic fertilizer can provide more targeted macronutrients to the crops
B) synthetic fertilizer remains in the soil longer than organic fertilizer does, reducing the volume needed and, therefore, the cost to the farmer
c) synthetic fertilizer adds to soil texture and increases the soil's water-holding capacity
organic fertilizer runs off more readily into waterways, leading to nutrient overload

A random mutation occurs and the GGA codon is changed to CGA, what effect does the substation have on amino acid

Answers

Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into mRNA,called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon--resulting in a CGA codon--generates a change in the coding amino acid resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.

Answer:

A. Glycolysis

Explanation:

Glycolysis is the first stage of cellular respiration, which occurs in the cytoplasm of the cell. Glycolysis does not require oxygen to occur, hence, it is carried out by both prokaryotic and eukaryotic organism.
