A common example of active transport, or moving a substance against its gradient, is the maintaining of a balance of sodium and potassium inside and outside a cell. Obviously too much sodium inside the cell would cause cell death. So, the cell must actively regulate how much sodium is allowed in through the membrane.

The trabeculae of spongy bone are oriented somewhat randomly but towards lines of stress, making them useful in preventing stres

ElenaW [278]

It, is True, the assertion is accurate as Trabeculae bone in spongy bone serves the following purposes:

The main functional role of trabecular bone is to transfer external stresses from joints into the cortical bone while also providing strength.

Trabecular bone, also known as cancellous bone or spongy bone, is a very porous kind of bone seen in animals. Blood veins abound, and the bone marrow is red. The flexible bone is frequently located at the extremities of the longer bones (the epiphyses), which are surrounded by the thicker, more compact bone. Additionally, it is found inside the vertebrae, ribs, skull, and bones in the joints. Compared to flexible bone, which is softer and more pliable, compact bone is stronger and more stiff.

Answer:

Tolerance.

Explanation:

Ecological succession may be defined as the change of an species, its structure and change in the ecological community with time. Two main types of succession are primary succession and secondary succession.

The earlier plant stage does not affect the late successional plant stages. These two plant stages does not have direct competition, they are showing the tolerance model. The different species tolerate the different successional stages of each other.

9. Based on your findings in Steps 5-7, what is the relationship between

Soloha48 [4]

Hello. You forgot to add the diagram required to answer that question.

The diagram can be seen in the figure attached below.

Answer:

According to the diagram, James Carnegie and Czar Nicholas II are third cousins. On the other hand, Tsar Nicholas II was the great-uncle of Countess Xenia.

Explanation:

The figure below shows the genealogical diagram that allows us to see the degrees of relationship between the generations of a family.

At the beginning of the tree we can see at the beginning of the diagram that the marriage between Louise of Hess Castell and King Christian IX of Denmark generated daughters Alexandra and Maria.

Alexandra had a daughter named Louise and Maria had two children, Nicholas II and Princess Xenia.

With that, we can say that Louise was a first cousin of Nicholas II and Princess Xenia.

Louise had a daughter named Maud (who is a second cousin of Nicholas II and Princess Xenia) and later had a son named James Carnegie, who was a third cousin of Nicholas II and Princess Xenia.

Pricess Xenia, Nicholas II's sister, had a daughter named Irina (who was Nicholas II's niece). Irina had another daughter, named Irina (who was the granddaughter of Princess Xenia, making Nicholas II her grandfather) who later had a daughter named Countess Xenia (who was the great-granddaughter of Princess Xenia, and therefore Nicholas II was her great-uncle) .
