Answer: Option B.

One cell thick layer of flattened cells.

Explanation:

The circulatory system is a system or network in the body that consist of blood, blood vessels i.e arteries and veins , microvessels, lymph vessels and the heart. They are lined by simple squamous epithelium tissue, these tissue is one cell thick layer of flattened cells. These type of cells are flat with flattened nuclei and are permeable, that is they allow the passage of small molecules through filtration and diffusion. The circulatory system help to circulate blood through out the body from the heart.

Answer:

ONE-CELL-THICK LAYER OF FLATTENED CELLS

Explanation:

The circulatory system is lined by a simple squamous epithelium which is a one cell thick layer of flattened cells. It allows for passage of small molecules through the process of filtration and diffusion, The kind of epithelium is found in areas that require rapid diffusion of substances such as capillaries, alveoli, glomeruli of nephron. This epithelium is one celled to the basal lamina and contains flat cells.

Explain Charles Darwin evolution theory.
MA_775_DIABLO [31]

Answer:

Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.

What mammalian cells would not be a good source to observe dividing cells in an adult?.
denis23 [38]

Everlasting cells are cells that are incapable of regeneration. these cells are taken into consideration to be terminally differentiated and non-proliferative in postnatal lifestyles. This includes neurons, heart cells, skeletal muscle cells, and pink blood cells.

Pink blood cells (RBCs) fall right into a truly less complicated category. Mature RBCs do not divide. In truth, because mature RBCs do not even have a nucleus, those cells in reality can not do an awful lot of anything other than act as vessels for the hemoglobin with which they are jam-packed. New RBCs are made in the marrow within the mature human.

Because the mitochondria are the mobile website for oxidative metabolism, where glucose is damaged all the way down to carbon dioxide and water to release energy, and because purple blood cells lack these organelles they cannot break down glucose absolutely aerobically.

The volume of blood remaining in the ventricle as ventricular diastole begins is called the __________.
Vinvika [58]

Answer:End - diastolic volume

Explanation:

End-diastolic volume is the amount of blood that is in the ventricles before the heart contracts. Doctors use end-diastolic volume to estimate the heart’s preload volume and to calculate stroke volume and ejection fraction. These different measurements indicate the health of a person’s heart.

You incubate isolated intact mitochondria in a buffered solution containing succinate (an oxidizable substrate) and ADP plus Pi.
telo118 [61]

Answer:

No Oxygen will be consumed, and there will also be no ATP production.

Explanation:

No Oxygen will be consumed, and there will also be no ATP production.

The blockage of  the binding of Oxygen with cytochrome C enzyme occurs, and this greatly decreases the cellular uptake of oxygen.

Therefore, in the presence of cyanide, ATP production is inhibited due to blocked oxygen utilization.

Stella [2.4K]

Answer:

  0.859 minutes of arc

Explanation:

The arc length for a given radius and angle in radians is ...

  s = rθ

So, the angle is ...

  θ = s/r

For the given geometry, the angle in radians is ...

  θ = (0.75 mm)/(3000 mm) = 0.00025 radians

In minutes of arc, this is ...

  (0.00025 radians)(60 minutes/degree)(180 degree/(π radians)

  = (0.0025)(60)(180)/π minutes

  ≈ 0.859 minutes

The angle subtended is about 0.859 minutes of arc.
