Answer:
The correct answer is option a. "Plasmodial slime mold".
Explanation:
Plasmodial slime molds, are comprised of a single "supercell" with thousands or millions of nuclei within it. These organisms are formed by the fusion of multiple flagellated cells. The formation of these single celled organisms depend on the presence of enough food source. Typically, plasmodial slime molds have a diameter of 3 to 4 centimeters, but they can growth up to 30 centimeters.
Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
Answer: I think it is probably c
Explanation:
Answer: lower atmospheric pressure
Explanation:
During the inspiration process the diaphragm, and external intercostal muscles. The contraction of the diaphragm causes the increase in the size of the thoracic cavity this causes the contraction of the external intercostal muscles. As a result of this the ribs and the sternum get elevated.
This causes the lungs to expand, and increasing the volume of the air passage. In this response the air pressure inside the lungs reduces below the air outside the body. Thus this facilitates the movement of the gases from a region of high pressure to low pressure, this way the air rushes into the lungs.
If there were no patterns in nature everything would be complicated. Atoms and all the little things would be different meaning our body structures would be different and the plants would be different too.
