Bacteria will multiply so fast between
41-135 degrees Fahrenheit. Bacteria
can grow rapidly in the TDZ, also known as the Temperature Danger Zone, which
is 41f - 140f. Generally 37 degrees - body temperature. However some,
such as fungi, prefer lower temperatures as they are found on the outside of
the body. Similar some bacteria.
<span>The ovaries produce estrogen and progesterone in women. Both play an important role in the menstrual cycle: estrogen stops FSH production and stimulates LH release by the pituitary gland. Progesterone maintains the uterus’ lining. Men also produce estrogen, though at lower levels, and this is done through changing testosterone into estrogen with an enzyme.</span>
Answer:
d. all endothelial cells would be venous
Explanation:
The Notch signaling pathway is a cell signaling system which consist basically of 4 NOTCH genes ( NOTCH1, NOTCH2, NOTCH3, and NOTCH4) each of them having the information to build a particular cell membrane receptor protein.
It has been demonstrated in zebrafish embryos that Notch signaling are highly determinant factors during vascular development, and a key function of these genes was specifically to regulate the differentiation of arterial fate in endothelial cells.
Notch signaling-deficient embryos showed a loss of expression of arterial markers such as ephrinB2 from arterial vessels with an accompanying expansion of venous markers into normally arterial domains. In contrast, embryos in which Notch signaling had been ectopically activated, meaning an activation out of "proper" place (where not expected, e.g. venous endothelial), exhibited the contrary phenotype, this is a suppression of vein-specific markers with ectopic expression of arterial markers in venous vessels.
To summarize, when Notch is supressed (in this case inhibited with a specific Notch inhibitor) arterial fate of endothelium is not followed, and venous fate is stablished. Thus, endothelial cells (those expected to form venous tissues but also arterial ones) would specified as venous.
Answer:
Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
Explanation:}
Answer:
This structure provides support and protection for plant cells = Cell Wall
This is a large, central fluid-filled structure that provides turgidity = Vacuole
A thin semipermeable barrier around the cell which regulates what enters and leaves the cell = Cell membrane
The control center of the cell = Nucleus
It is often described as the cells Power Plant = Mitochondria
This is used by plant cells for photosynthesis = Chloroplast
Hope this helps :)
Plz mark Brainliest :D
Explanation:
The giant blue thing is the vacuole
The thin yellow line is the cell membrane
The yellow and orange ball is the nucleus
The light green thing with zig zag lines is the mitochondria
The dark green thing inside the cell is the chloroplast
The thing outside the cell is the cell wall its green
