Answer:
Constance's body is capable of producing insulin, but the insulin is misused. her condition is known as pre-diabetes.
Explanation:
Prediabetes is the preliminary stage of diabetes mellitus where all the symptoms necessary for the diagnosis of diabetes are absent, but the blood sugar is abnormally high.
Prediabetes is associated with obesity (especially abdominal or visceral obesity), high triglyceride and / or low HDL cholesterol dyslipidemia and hypertension. Therefore, it is a metabolic diathesis or syndrome, and it usually does not produce any symptoms, and the only symptom is high blood sugar.
Impaired fasting blood glucose and impaired glucose tolerance are two types of prediabetes that are similar in clinical description (high blood glucose levels in both cases) but are physiologically different. Insulin resistance, insulin resistance syndrome and prediabetes are closely related and have overlapping aspects.

Should commercial fruit farmers be allowed to use ethylene to accelerate the ripening of fruit for the market? Why or Why not?
The answer is: NO
Accelerated ripening of fruits lowers the quality of the fruits because it circumvents the natural process of ripening. In some cases of accelerated ripening, one finds a premature fruits looking ripe. In other cases, it causes ununiform ripening and also causes hastened senescence reducing shelf life.
The commercial fruit farmers should not be allowed to use ethylene.
Though ethylene is a natural growth regulator in the plant, if it is not applied in limited quantity it produces adverse effects such as overly ripened fruits, yellowing of green fruits and fruit becoming excessive soft and loose to pre maturity. It leads to chlorophyll destruction and also inhibits vegetative tissue. It also inhibits auxin transport, flower development, shoot and root growth.

Dna is wrapped around proteins called _____ to form a chromosome.
Final answer:
DNA in eukaryotic cells is wrapped around histone proteins to form nucleosomes, which create the 'beads on a string' structure. These are further compacted to form chromosomes, especially during cell division.
Explanation:
DNA is wrapped around proteins called histones to form a chromosome. Eukaryotic DNA, which is negatively charged due to phosphate groups, is tightly wound around these positively charged histone proteins. The formation begins with DNA winding around an octamer of histones to create a structure known as the nucleosome. This structure resembles "beads on a string", with each "bead" representing a nucleosome and the string being the linker DNA.
The arrangement is then coiled into a 30 nm fiber and, during cell division, becomes even more densely packed into chromosomes by additional scaffold proteins. This packaging method is central for fitting DNA into the nucleus of eukaryotic cells and for the regulation of gene expression.
What is the correct chromosomal condition at prometaphase of mitosis?
In prometaphase of mitosis, chromosomes compact and become visually distinguishable, the nuclear envelope breaks down, and the mitotic spindle's microtubules attach to the kinetochores on the chromosomes.
Explanation:During the prometaphase of mitosis, the chromosomal condition is that each chromosome compacts and becomes visually distinguishable under a light microscope. The nuclear envelope begins to break down, and the chromosomes, composed of two sister chromatids, free in the cytoplasm of the cell. Moreover, the microtubules from each centrosome, constituents of the mitotic spindle, attach to a specific protein structure on the centromere of each chromosome called a kinetochore. This ensures that each daughter cell receives an equal distribution of chromosomes during the ensuing mitotic phase, metaphase.

If aden- means gland, what word could mean a tumor of the sebaceous glands?
Final answer:
The term for a tumor of the sebaceous glands combining 'aden-' for gland and '-oma' for tumor is 'sebaceous adenoma', which is a benign growth originating from the oil-producing sebaceous glands.
Explanation:
If the term "aden-" refers to a gland and we are discussing a tumor of the sebaceous glands, the medical term for such a tumor would often include the suffix "-oma", which refers to a tumor. Thus, the word that could describe a tumor of the sebaceous glands is "sebaceous adenoma". A sebaceous adenoma is a benign tumor that arises from the sebaceous glands which are responsible for producing sebum.
Sebum is the oily substance that helps to lubricate and protect the skin and hair. While sebaceous adenomas are usually not serious and often do not require treatment, they could potentially indicate an underlying condition if they are multiple or irregular.

Habitat destruction is the leading cause for declining populations of species on our planet. Due to human development, industry, and forestry, humans are destroying the habitat of many species at an alarming rate. Consider the bald eagle. The bald eagle population was threatened in the late 60s and early 70s. Thanks to an aggressive bald eagle protection program, bald eagle numbers in the wild have soared as seen in the population graph above. The bald eagle's population very nearly reached extinction. Why did the bald eagle's declining population make it more vulnerable to extinction? A) As populations decline, reproduction stops B) As populations decline, less resources are available C) As populations decline, there is less genetic diversity D) As populations decline, birds migrate farther away from other populations
C) As populations decline, there is less genetic diversity
As populations decline, there is less genetic diversity The bald eagle's population reached alarmingly low numbers due to habitat loss and with low populations, there is not as much genetic variability. With fewer variations, a species survival is difficult to overcome without conservation efforts.

How does the structure of a red blood cell relate to its function?
Due to its biconcave shape, red blood cells have the ability to deliver the amount of oxygen to various organs and tissues of the body of an individual.
What do you mean by Red blood cells?Red blood cells may be defined as a type of blood cell that is made in the bone marrow and found in the blood which contains hemoglobin.
Red blood cells do not have a nucleus in their structure and contain hemoglobin which increases the affinity of oxygen to bind with it and transport this bound oxygen to the whole body through the transport of bounded oxygen with hemoglobin particles.
Therefore, the function of RBCs with respect to their structure is described above.

The ends of DNA molecules form telomeres that help keep the ends of chromosomes from sticking to each other. Why might this be especially important in germ cells, which go through meiosis and make haploid gametes?
The telomeres which keep the ends of chromosomes from sticking to each
other is important because it helps to prevent mutation and death of
offspring.
Telomeres are referred to as the ends of the chromosome. They prevent
sticking together of the homologous chromosomes during the process of
separation in meiosis.
If the telomere is absent and sticking together happens then one of the
resulting gametes will have extra chromosome with a corresponding
deficiency in the chromosome of the other thereby resulting in lower
reproductive rate, mutation and death

If an experiment starts with 6 bacteria cells and ends with 96 bacteria cells, how many generations did the cells go through?
In order to calculate the number of bacteria generations, you use logarithms. Taking the log base 2 of the final number of bacteria divided by the initial number gives approximately 4 generations.
Explanation:The generational growth of bacteria cells is typically exponential, doubling with each generation. Since we're starting with 6 cells and ending up with 96, we need to figure out how many times 6 needs to be doubled to get 96. This can be calculated by using the formula of logarithm base 2. Firstly, divide 96 by 6 to get approximately 16 then, calculating the base 2 logarithm of 16, gives us about 4. So the cells went through about 4 generations.

Which plane shows brain structures as they would be seen from the front?
The plane that shows brain structures as seen from the front is the frontal or coronal plane. This vertical plane divides the brain into front and back regions. It runs parallel to the eyes or ears.
The vertical plane that shows brain structures as they would be seen from the front is called the frontal or coronal plane. This plane runs parallel to the eyes or ears and divides the brain into front (anterior) and back (posterior) regions. For example, a slice of the brain taken along the coronal plane would look similar to slicing a loaf of bread with the eyes at the front, allowing you to see both the left and right side structures positioned frontally.
Endotherms normally have larger brains than ectotherms. What connection do you see between the two characteristics?
Answer:
The energy required by brain cells are 10 times more than the normal body cells. Ectotherms are cold-blooded animals so they need heat energy from the sun to remain active but endotherms can regulate their body temperature due to large brain.
So the increase in temperature helps in increase in the size of the brain in endothermic animals. The basal metabolic rate in large endotherm is 10 times less than the basal metabolic rate of large ectotherms which supports the large brain in endothermic animals.
The endothermic brain contains more glial cells than the ectothermic brain this is also the reason that the brain of endotherms is larger than the brains of ectotherms.

Property Expected from Muscle Fibers..?
Muscle fibers are complex multicellular units equipped with several components that enable their functional properties, most importantly muscle contraction. These include the sarcolemma (plasma membrane), sarcoplasm (cytoplasm), sarcomeres (functional unit), and several other structures and proteins. There are also different types of muscle fibers that use different metabolic methods to generate ATP, the energy for muscle contraction.
Explanation:Skeletal muscle fibers are long, multinucleated cells contained within a plasma membrane, the sarcolemma. The cytoplasm of the cell is referred to as sarcoplasm, which along with the specialized smooth endoplasmic reticulum or sarcoplasmic reticulum plays an important role in the property of muscle contraction through the release and retrieval of calcium ions. The functional unit of a muscle fiber is the sarcomere, an organized arrangement of actin and myosin filaments that, through a series of steps, shorten to produce movement.
The number of sarcomeres and myofibrils within a muscle fiber, which can be influenced by factors such as hormones and stress, can result in hypertrophy, increasing the mass of a muscle, or, if muscle use is decreased, atrophy, wherein the muscle mass decreases. The three types of skeletal muscle fibers, slow oxidative, fast oxidative, and fast glycolytic, each use a different metabolic method to generate ATP, the energy for muscle contraction.
