Answer:
The correct answer is cell organelles.
Explanation:
A unique membrane-bound composition, which is found inside the eukaryotic cell's cytoplasm, that is, in plants and animal cells is termed as cell organelle. Some of the examples of cell organelles found within the cells of eukaryotes are endoplasmic reticulum, Golgi complex, mitochondria, chloroplast, etc.
All these organelles play an essential function for the proper functioning of the cell, like chloroplasts found in plants play an essential role in the process of photosynthesis, and mitochondria both in plants and animals are regarded as the powerhouse of the cell.
Answer:
Lamarck:
The inheritable traits of species may change over time.
Malthus:
In every species in nature, some individuals survive while may others die.
Hutton, Lyell:
The environment of organisms may change over time.
Explanation:
Darwin's revolutionary ideas were influenced by a number of scientists and thinkers of the time:
Jean Baptiste Lamarck:
A botanist and zoologist, Lamarck, for, the first time, proposed the idea of evolutionary changes or adaptations in organisms in response to changes in the environment. He introduced the concept of inheritance of acquired characters.
Thomas Malthus:
Thomas Malthus was not a biologist, but an economist who proposed the ideas that at the rate of the current population growth, human population would eventually suffer from famine and starvation.This would lead to the deaths of the weakest of the population. This idea inspired Darwin to formulate the idea of "the survival of the fittest".
Charles Lyell and James Hutton:
Charles Lyell and James Hutton were famous geologists who greatly influenced Darwin with their theories about the beginning and evolution of the Earth. Charles Lyell proposed that the present state of the Earth was a result of small, gradual changes. James Hutton theorized that the processes that too place at the beginning of the Earth were still in progress.
Lyell and Hutton's work paved the way for the formulation of the theory of natural selection.
What this student is doing is collecting data. So, he wants to check how many life forms there are in the waters nearby. In order to do so, he has to take a sample, and look at it through a microscope so as to determine the number. So, he collected a sample which is his data. He is not drawing conclusions yet, but rather counting these organisms. He is not making a peer review - his peers aren't even mentioned here. He is not forming a hypothesis because he is just counting at this point.
Answer:
The answer is 3. Double Helix.
