Answer:
Explanation:
The layer most likely to have organisms which lived at the same time as the bird species is Layer 2. Layer 2 is closer to layer 3 than any of the other layers listed. Assuming that layers were laid down sequentially as time passed, it is reasonable to assume that layer 2 was laid down most closely in time to layer 3.
That is known as a tumor. Or cancer
Answer:
The yellow form can exist in both the "live yellow" and "heat-killed purple" forms.
Explanation:
To carry out these transformation tests; for example change of purple structure form into the yellow structure; DNA, RNA, and proteins will be confined from the yellow structure and infused to heat-killed purple structure each in turn in singular examinations. At the point when DNA will be changed into heat-killed purple structure form, it is changed over and converted to the yellow structure form. In this way, the yellow structure form can be acquired from live yellow just as heat-killed purple structure (changed with DNA or changing guideline from the yellow structure).
A constant factor could be the dose of the drugs and the species of the rats used.
<h3>What is a constant factor?</h3>
In an experiment, a constant factor is one that is not allowed to change al through the experiment. This one must be held as the same and not allowed to vary. A constant factor could be the dose of the drugs and the species of the rats used.
The factor that would be different for the experimental group and the control group the administration of the new drug.

Answer:
is a process in which deep, cold water rises toward the surface. ... Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity
