Epithelial cells are held together by tight junctions, adhering junction and desmosomes and attach to a specialized form of extracellular matrix called the basement membrane. Epithelial cells are polarized with an apical surface facing the lumen or external environment and a basal surface facing the basement membrane.
Answer:
Follicle stimulating hormone (FSH)
Explanation:
The correct answer for the given question that fills up the blank is " follicle stimulating hormone (FSH) ".
The follicle stimulating hormone (FSH) is responsible for the initiation of the follicle egg development.
The follicle stimulating hormone (FSH) also stimulates the secretion of the estrogen during the first half of the ovarian cycle.
Answer:
Hematuria is the presence of blood in he urine. Blood can get into the urine because an infection or as it is usual, kidney stones. It could be annormal but not necessary.
Answer:
The answer is: nasal conchae
Explanation:
The nasal conchae, also known as turbinates, are the elongated curled shelf of bone that protrudes into the nasal cavity. It is present on the lateral surface of the nasal cavity.
It is responsible for the directing the airflow direction, heating, filtering and humidification, of the air inhaled through the nose.
B-Ectoderm
C-Mesoderm
D-osteogenesis
Answer:
the answer is C
Explanation:
hope it helps
b. decrease
c. be unchanged
As volume increases, the pressure decreases since both are inversely proportional with respect to Boyle’s law.
Explanation:
An inverse proportionality exists between the volume and the pressure, this law will hold true if there are no changes in the molecules number and the temperature.
At an initial state of fixed quantity of gas, this law helps to determine changes in the pressure and volume. This law was introduced in the year 1662. According to this law, when the volume increases then the pressure in the contained gas would decrease. This is because of the reason that there exists an opposite relationship between the pressure and the volume.
b. anaerobic respiration in the cytosol
c. glycoludid in the cytosol
d. ATP that is stored while the heart is not contracting
e. creatinine phosphate
Answer:
The correct answer to the question: Energy for contraction of myocardial cells comes primarily from:___, would be, A: aerobic respiration in the mitochondria.
Explanation:
In order for the heart muscles (myocardium) to contract, there are a series of elements that need to be present. One of them, and most vital, is calcium, which will activate the connection of myosin and actin, the filaments in cardiomyocytes, the very units of muscular tissues in the heart. However, even if calcium were present, without ATP, the molecule of energy that will allow the process to happen, then contractions would not be possible. There simply would not be energy to allow the chemical reactions. The one organelle within the cell that is responsible to ensure there is ATP available, is the mitochondria. This production of ATP by mitochondria, happens through the process of aerobic respiration. This is why the answer is A.
