Answer:
Macula densa cells, lower and renin.
Explanation:
Macula densa cells in the kidney detect lowers blood pressure which causes renin to be released from the juxtaglomerular cells which is an enzyme. The arterial cells observe the drop in blood pressure, and the decrease in Na concentration is transfer to them by the macula densa cells. The juxtaglomerular cells then release an enzyme called renin. Renin converts angiotensinogen which is a peptide, or amino acid derivative into angiotensin-1.

Postpartum urinary retention can be caused by: a. Stretching of the ureters during delivery b. Decreased sensitivity to bladder fullness c. Contraction of bladder muscles caused by oxytocin d. The effects of proteinuria and lactosuria on the bladder
Answer:
a. Stretching of the ureters during delivery
Explanation:
Postpartum urinary retention is defined as the stretching if the uterus or the genitourinary tissue which occurs in most of the women during vaginal deliveries. The postpartum bladder is vulnerable to the urinary retention. This occurs due to the physiological changes in the pregnancy period. During delivery through vagina, the genitourinary tissues becomes edematous and also gets traumatized form the labor process and thus stretches the ureters during the delivery time. But it returns to normal after 4 to 6 days of diagnosis.
Hence the correct option is (a).
species separated by inability of hybrid offspring to produce offspring of their own

The thin outer layer of the skin is called the _____.
endodermis
dermis
fatty layer
epidermis
The thin outer layer of the skin is known as the Epidermis. So, the correct option is D.
What is Epidermis?The epidermis, which is referred to as the skin's outermost layer, shields the body from the elements. Depending on the kind of skin, the epidermis can be as thin as.05 mm on the eyelids or as thick as 1.5 mm on the palms and soles of the feet.
The body is shielded by the epidermis from harmful substances like chemicals, pathogens (bacteria, viruses, fungus, and parasites), and ultraviolet (UV) radiation. The epidermis, which is the skin's outermost layer and gives skin its tone, serves as a waterproof barrier. The dermis, which lies underneath the epidermis, is made up of hard connective tissue, hair follicles, and sweat glands.
Thus, the correct option is D.

Mode of action of aldehydes and Quaternary ammonium compounds is
Answer:
Aldehydes have antibacterial, antifungal, antiviral and sporicidal activity. These are helpful to destroy the spores of Bacillus subtilis and Clostridium sporogenes. Glutaraldehyde and formaldehyde are commonly used aldehydes in disinfectants.
Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.
Describe the relationship between the surface area and the volume of a cell. Analyze the data and explain why cells are often flattened instead of cube-shaped.
Answer:
Inverse relation.
Explanation:
There is an inverse relationship between the surface area and the volume of a cell because one increases the other decreases. When a cell grows bigger in size, its internal volume enlarges and the cell membrane start expanding. Unfortunately, the volume increases more rapidly than the surface area of the cell. So the surface area available to pass materials to a unit volume of the cell steadily decreases. Cells are often flattened instead of cube-shaped because the surface area increases. Due to surface area increases, more materials to be absorbed through the cell membrane at a greater rate than that of a cell with smaller surface area.
Three color receptors that responded in an opponent-process fashion had been proposed by ______; this arrangement was later verified by ______ in monkeys.
This question seems to be incomplete. However, there is enough information to find the right answer.
Answer:
Three color receptors that responded in an opponent-process fashion had been proposed by Hurvich and Jameson; this arrangement was later verified by DeValois in monkeys.
Explanation:
In "An opponent-process theory of color vision" (1957), Hurvich and Jameson developed the opponent-color system. In "Color Vision Mechanisms in the Monkey" (1960), De Valois confirmed the existence in monkeys of color-opponent ganglion cells in the retina and color-opponent cells in the lateral geniculate nucleus of the thalamus. De Valois himself states in his research that there´s a clear close parallel between the behavior of what he calls "on-or-off cells" and the findings o Hurvich and Jameson.
Which of the following statements correctly identifies and describes the type of covalent bond found between
oxygen and hydrogen in water molecules?
hydrogen bonds because hydrogen is more electronegative than oxygen
O polar covalent bonds because oxygen is more electronegative than hydrogen
O polar covalent bonds because hydrogen is more electronegative than oxygen
Answer: O polar covalent bonds because oxygen is more electronegative than hydrogen
Explanation:
In the water molecule the two hydrogen atoms and one oxygen atoms forms the chemical structure in this the covalent bond is formed between hydrogen and oxygen and this is formed due to sharing of electrons between hydrogen and oxygen and oxygen being electronegative requires two electrons to complete its valency which are provided by two electrons each from one hydrogen and the O polar covalent bond is formed by this way.

Answer:
C. Point B
Explanation:
The exposed curve represents a logistic growth model. Population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.
Referring to population size as N, when
N<K, the population can still grow. N approximates to K, the population´s growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
Point A: During this period, the population size is relatively stable. Little growth is expressed. Point B: At the beginning of this period, population growth increases softly. The more individuals are in the population, the more that reaches sexual maturity and get to reproduce, leaving fertile offspring. This fertile offspring also get to reproduce and leave more fertile individuals. At the end of the period, the curve shows a sharp slope, reflecting the significant increase in the population reproductive rate. Point C: At the beginning of this period, the population keeps on growing exponentially. But at the end of the period, the curve tends to stabilize, meaning that the population stops growing in size so fast. The population slow and gradually reaches the equilibrium point, K.Point D: The population got to stabilize.Answer:

Explain the role of cellular respiration in a cell.
Answer:
Every cell performs a type of cellular respiration as it is required to produce energy. The point of cellular respiration is to turn high-energy molecules, know as glucose, into ATP, a form of usable energy. There are two types of respiration, aerobic and anaerobic. Aerobic goes through 3 stages and produces the most ATP by using oxygen and releasing carbon dioxide. Anaerobic does the same job but only uses one stage and produces much less ATP. This process gives the cell energy and continues the carbon cycle.

If the stomata remain closed due to water loss, what happens to the concentration of CO2 and O2 in the leaf
Answer:
Fixation of oxygen occur instead of carbondioxide.
Explanation:
If the stomata remain closed due to water loss, the concentration of carbondioxide decreases and oxygen increases in the leaf because of the fixation of oxygen instead of carbondioxide by rubisco. The plant takes carbondioxide from the atmosphere when the stomata is open so when the stomata is closed there is no other way for getting carbondioxide into the leave so the oxygen is now being fixed by our rubisco enzyme to that five-carbon compound instead of carbon dioxide.
