Answer:
The sample size of the animal was too small , not large enough to conclude that the effects of the chemicals on Salamander was the actual cause of toxicity and weight loss.
It is possible that the drop in weight may be as a result of other environmental factors; agitation from background noise and sudden exposure to new environments,, fluctuation in temperature of the surrounding environments , lack of feed supply or others
However, if there was many salamanders available; and most reacted to the chemical exposure in the same way then it can be concluded that, toxicity of the chemical is the causative factor.
Explanation:
This is false
hope that helps!
C.)The waste of animals returns nitrogen to the nitrogen cycle.
<h2>Resilience </h2>
Explanation:
The emergence of a meadow in a recently burned forest represents a resilience mechanism
Resilience is defined as the capacity of a ecosystem to react to a disturbance by resisting and recovering quickly from it
In a burned forest where everything was destroyed the emergence of meadow is the capacity of the habitat to recover from the disturbance of burning and inhabiting the place, there is a quick arrival of habitat in the form of meadow
Answer:
The connection between cancer cells stimulates uncontrolled proliferation and tumor growth
Explanation:
In the tumor, cancer cells are interconnected by different types of proteins, which may act as receptors or amplify oncogenic signals. For example, in breast cancer, it has been shown that oncogenic cells are often connected through E-cadherin proteins that mediate their adhesion, thereby stimulating the cell movement and invasion (characteristic of tumor metastasis). In this case, E-cadherin membrane proteins function by enhancing effector response in cancer cells. The nucleus acts as the control center of the cell that modulates the expression of tumor suppressor genes in order to inhibit tumor metastasis.
