Answer:
Cerebral cortex of the Cerebrum
Explanation:
The body directs our body's internal functions. These functions are made possible by four major regions of the brain viz: The Cerebrum, Diencephalon, Cerebellum and Brain stem.
The Cerebrum is the largest brain structure, making up most of the total brain, and a part of the forebrain. The cerebrum's prominent outer portion, the cerebral cortex, not only processes sensory and motor information but also enables CONSCIOUSNESS (our ability to consider ourselves and the outside world), thoughts, emotion, reasoning and memory.
The cerebral cortex is composed of the right and left hemispheres joined by the corpus callosum. Each cerebral hemisphere can be subdivided into four lobes (Frontal, Parietal, Temporal, and Occipital) associated with different functions.
Genetic drift happens by chance and can make an allele disappear completely from a gene pool, even if it was a desirable trait that should have been passed down to offspring. The random sampling style of genetic drift shrinks the gene pool and therefore alters the frequency the alleles are found in the population.
The source of bacteria in the
culture tube in model 1 is from a swab of a desktop. Moreover, there are four variants
in the E. coli culture from the initial swab and the variants of E.coli found
on the dish grown with triclosan are evolution and selection.
Answer:
The correct answer is option 3. a nucleus.
Explanation:
The first genetic material present in the early organisms were RNA which was present in the microscopic organisms back then 3.5 billion years ago which means it is normal to have RNA in such microfossils chemical analysis.
Since, the nucleus was not present in early life forms of prokaryotes like bacteria. so, it is unusual to find nucleus in the fossils of stromatolite rocks.
Thus, option III is the correct answer.
The answer is centrioles.
Hope this helps!!
