Answer: A niche is the role an organism plays in the ecosystem.
Explanation: A niche also determines how the organism interacts with other organisms in an ecosystem
The correct answer is - False.
To trace the correlation between the rock layers by using fossils can be a big mistake, though occasionally it may provide the proper information, still it will be relying on luck.
The case is actually the other way around, the fossils can be correlated by using the rock layers, because each layer of rocks represents some time in the geologic past.
The fossils, on the other hand, are much more easy to be moved through the layers over time, because there can be disturbances, adjustments in the crust, or the rocks can change their composition under the influence of multiple factors. All of that can contribute to the fossils ending up at places where they aren't expected to be, so using them to correlate the rock layers will not be a very useful method.
Lymphedema is the condition I believe.
Answer:
B. It will become larger by taking in nutrients.
Explanation:
Growth is a characteristics of every living thing and is portrayed by an increase in size (height and weight) of such organism. This question depicts an image of a unicellular organism called EUGLENA.
Like every other living organism, for Euglena to grow, it must take in nutrients necessary for its growth. Euglena does this by performing photosynthesis or by absorbing it from their immediate environment. As it grows, it takes in nutrients and uses it for growth, which is evident by its increase in size i.e. gets larger.
<span>The phrases Inherited genetic variations are caused by genetics only. They caused by crossing over and assortment in the development of sex cells in meiosis and Mutations are always harmful are false. There are several factors that influence genes, the way they're transmitted and expressed. This is known as epigenetics. The random joining of sex cells can also be a source of genetic variation. Mutations also cause variations in genetic sequences are true</span>
