What is obesity? How is it different from being overweight?
Answer:
the term "obese" generally means a much higher amount of body fat than "overweight."
Explanation:
Answer: it is like being over weight
Explanation:
Being overweight or obese are both terms for having more body fat than what is considered healthy. Both are used to identify people who are at risk for health problems from having too much body fat. However, the term "obese" generally means a much higher amount of body fat than "overweight.
The absolute refractory period of an action potential:___________
a. prevents summation of action potentials
b. allows a neuron to ignore a second signal sent that closely follows the first
c. ensures one-way travel down an axon
d. A and B
e. A, B, C
Answer:
e. A, B, C
Explanation:
An action potential is a short event during which the membrane potential of an excitable cell increases and then falls rapidly. Membrane potentials correspond to potential differences across the membrane of excitable cells.
The absolute refractory period (P-RA) during which any stimulation is ignored, regardless of its intensity corresponds to the activation of fast sodium channels (quick response fibers) or calcium-sodium channels (slow response fibers). It begins in phase 0 of the action potential and ends in the repolarization phase (phase 3 for a fast fiber) when the membrane potential is sufficiently electronegative to restore the reactivation of these channels. It corresponds on the ECG to the interval between the onset of QRS and the top of the T wave.
The relative refractory period (P-RR) during which the cell is hypoexcitable. It corresponds to the start of the reactivation of the ion channels. Reactivation is incomplete and the action potential that results from stimulation during this period has unusual properties that expose conduction problems (block in phase 3) and may cause cells to desynchronize. Thus, an extra-stimulus which falls on the relative refractory period (R / T phenomenon) could cause ventricular tachycardia or ventricular fibrillation.
Thus; the absolute refractory period of an action potential prevents summation of action potentials, allows a neuron to ignore a second signal sent that closely follows the first and ensures one-way travel down an axon .
Which is a long-term effect of sun exposure?
a bright red rash after sitting in the sun
a stinging burn that is sensitive to touch
a change in skin complexion or sallowness
a cluster of freckles appearing on the skin
A change in skin complexion or sallowness is a long-term effect of sun exposure.

Hello. You forgot to enter the answer options. The options are:
A. Single-celled organisms can perform all of these functions, while multi-celled organisms can perform only some of these functions.
B. Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
C. Single-celled organisms can perform only some of these functions, while multi-celled organisms can perform all of these functions.
D. Neither single-celled organisms nor multi-celled organisms can perform all of these necessary functions.
Answer:
B. Single-celled organisms must perform all of these functions with one cell, while multi-celled organisms can have specialized cells for different functions.
Explanation:
As you already know, single-celled organisms have only one cell and must use it for all the metabolic processes you need to perform to survive. As this cell is not, often specialized in the process it needs to do, the process often takes a long time.
On the other hand, multicellular organisms have a variety of cells divided into several groups and with identical functions. In this case, the metabolic processes are done more quickly and often are done simultaneously.

Which of the following statements is true about photosynthesis and cellular respiration?
Photosynthesis takes place in the nucleus of the cell.
Cellular respiration takes place in the mitochondria of the cell.
Only photosynthesis occurs in all living things.
Both photosynthesis and cellular respiration occur in all living things
Answer:
b is correct
option 'a' is wrong photosynthesis take place in chloroplast
Cellular respiration takes place in the mitochondria of the cell, hence option B is correct.
The metabolic method through which cells liberate energy from the chemical interactions of food molecules and supply that energy for the vital functions of life is known as cellular respiration. Cellular respiration is a necessary function of all living cells.
Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. The plant consumes glucose and produces oxygen as a byproduct.
Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which is turned into energy.

A 50-year-old G3P3 comes to the office due to heavy periods, spotting between menses, fatigue and weakness. Over the past six to eight months, she has noticed a significant increase in the amount of her menstrual bleeding, currently requiring a box of 30 pads for each month. She has noticed an increase in the amount of blood clots and cramping pain during menses. Her previous history is significant for hypertension for 10 years, controlled with hydrochlorothiazide and a postpartum bilateral tubal ligation 20 years ago. She has no history of abnormal Pap smears and no sexually transmitted infections. Blood pressure is 138/84; pulse 82; respirations 20; weight 220 pounds; height 68 inches. On pelvic exam, uterus is approximately 10-week size. She is nontender on bimanual exam and no adnexal masses are appreciated.

When the ventricular myocardium receives an electrical impulse, it stimulates a
contraction that:
only pulls in deoxygenated blood from the body.
O pushes both types of blood to both the lungs and body.
only pushes deoxygenated blood to the lungs.
only pulls in oxygenated blood from the lungs.
Answer:
pushes both types of blood to both the lungs and body.
Explanation:
These fibers transmit the electrical impulse to the myocardium (cardiac muscle). The myofibers in the ventricular myocardium contract at the same time because the impulses are transmitted rapidly. When the ventricles contract, the blood from both ventricles is forced out through the pulmonic and aortic valves into the pulmonary and systemic circulation.
The electrical shock causes the heart's ventricles to contract and pump blood as it moves along the conduction channels, hence option B is correct.
What is ventricular myocardium?Before the two lower chambers of the heart may contract, the two upper chambers of the heart (atria) are activated first (ventricles).
Cardiomyocytes and fibroblasts make up the majority of the cells in the myocardium. Along with the extracellular matrix (ECM), blood arteries, lymphatic vessels, and nerve terminals, fibroblasts are dispersed throughout cardiomyocytes.
A thin layer of connective tissue connects the myocardium to the endocardium, the deepest layer of the heart wall.
Therefore, the heart valves are protected by the endocardium, which also borders the blood circulation chambers, hence option B is correct.
